Chen Yun went straight to the farm area.
The farm area is very large, occupying almost half of the second underground floor.
The space of more than a thousand square meters is empty.
Chen Yun walked to the center of the farm area chamber and waved his hand gently. The empty ground in front of him was instantly filled with a large number of alloy brackets, shelves, clips, LED plant growth lights, PVC pipes and other miscellaneous materials.
Chen Yun took a deep breath, and a blueprint for the assembly of a three-dimensional cultivation rack appeared in his hand.
Following the assembly steps in the instruction manual, Chen Yun pulled over the alloy components and began to assemble them.
The system's strengthening function cannot directly strengthen materials into finished products, nor can it turn cement, sand and gravel into houses out of thin air.
There needs to be a basic thing, and then the enhancement can be carried out on this basic object.
Therefore, Chen Yun needed to build the framework of the three-dimensional cultivation rack by himself, and then use other materials to strengthen the framework.
Fortunately, the assembly of the cultivation rack is very simple. You just need to find the corresponding components and then plug them together.
It didn't take long before the two growing racks were assembled.
The shelf on the left has four layers, with one meter between them.
The shelf on the right has ten layers, with half a meter between them.
The four-layer racks are used to grow food crops such as rice and wheat, while the ten-layer racks are used to grow vegetable crops.
Chen Yun planned to divide the farm area of more than 1,000 square meters into two parts of 700 square meters and 300 square meters.
The 300 square meters will be left empty for now, and if there is enough energy in the future, you can try some farming.
The remaining 700 square meters of space are divided into a 300 square meter grain planting area and a 400 square meter vegetable planting area.
"Based on the actual planting area, there are now nearly 4,000 square meters of vegetable area and more than 1,200 square meters of grain area." Chen Yun calculated in his mind.
"With this cultivated area, just looking at the grain, if we harvest twice a year, the annual output would be enough to feed one person for ten years!"
"But this kind of farming consumes a terrifying amount of energy. If we can solve the energy consumption problem, then we won't have to worry about food at all..."
After pondering for a long time, Chen Yun raised his head, stretched out his hands, and pressed them on the three-dimensional cultivation racks on both sides.
Use your mind to call out the light curtain and click [Strengthen].
[Three-dimensional cultivation frame components and other materials have been detected. Do you want to consume these materials to specifically strengthen the current three-dimensional cultivation frame? ]
[Strengthening direction: expansion.]
[Required survival points: 200 points.]
"Yes." Chen Yun muttered to himself.
[Confirmed to strengthen. Survival points consumed: 200 points.]
[Strengthening…]
A progress bar appeared on the screen.
As the progress bar filled up, the two shelves and miscellaneous materials in front of him disappeared.
[Strengthening Successfully! ]
The farm area chamber is no longer empty.
In the left area, several rows of silver-white alloy skeletons nearly six meters high stand tall, as if growing out of the walls and the ground, and are deeply embedded in the dark gray walls.
Each layer is paved with a smooth silver-white cultivation platform, which glows dimly under the illumination of the LED light panels on the top of each layer, and the grooves and drainage holes on the platform are clearly visible.
Most of them are four stories high, and a small part are ten stories high.
On the right, a network of crisscrossing white pipes of varying thicknesses formed the landscape. These pipes were perforated with evenly spaced holes and studded with neatly arranged planting cup connections. The main circulation pipe connected to the central area of the farm.
The LED light array on the top of the chamber emits uniform and bright light, making the entire farm area as bright as day.
In the center of the 700-square-meter space in the planting area of the farm, the dark gray ground is slightly raised to form a half-foot-high base.
The massive liquid storage tank, monitoring and control cabinet, and circulating water pump were securely fixed to the base. The complex pipe connections automatically extended, seamlessly connecting to the newly formed pipe network and the reserved water supply interface.
Chen Yun stepped forward, his fingers brushing against the cool alloy frame, then touching the smooth surface of the pipe. He couldn't help but sigh, "These devices should be no worse than those on professional farms."
Looking at the fully equipped farm area, Chen Yun nodded with satisfaction.
Now the equipment is complete, all that's left is sowing. Once I learn the soilless cultivation and hydroponic techniques, I can start planting.
After stretching, Chen Yun turned off the lights in the farm area and came to the last room on the second underground floor - the garbage area.
As the name suggests, the garbage area is where domestic garbage and wastewater are processed.
As long as we live, as long as we are alive, we will inevitably produce garbage and wastewater.
But if you discard it anywhere or discharge it at will, you will inevitably expose yourself and bring risks.
Therefore, the treatment of garbage and wastewater is of vital importance.
Chen Yun waved his hand and took out three small garbage incinerators and two small sewage treatment plants from the space.
Place both hands on the incinerator and sewage treatment plant and select [Enhance].
Will other incinerators and sewage treatment plants be used, and will the current incinerators and sewage treatment plants be comprehensively strengthened?
[Required points: 400.]
[Insufficient points balance.]
Chen Yun was slightly stunned, "I didn't even notice the points consumption, now there are only 162 points left.
"It seems I can only wait until the points are settled tonight before continuing to strengthen."
I took out my phone and checked the time. It was already past three o'clock.
Chen Yun shook his head. "That's all that's happened. Let's go to sleep first."
Turning back to the old house on the ground floor, Chen Yun simply washed up, lay down on the bed and fell into a deep sleep.
The next morning, Chen Yun woke up early.
After eating something casually, Chen Yun came to the yard.
Taking out a water pipe from the space, Chen Yun connected one end of the interface to the faucet in the yard, pulled the other end down to the water source area in the basement, and connected it to the water inlet interface of the water purification equipment.
Go back to the yard and turn on the faucet.
June is the busy farming season, and crops in the fields need to be weeded and watered. Almost every household uses a lot of water, so there is a shortage of tap water, and there are often problems with low water flow from the taps or even water outages.
The water tank has a capacity of one hundred tons, so it will take a long time to fill it up.
So start storing slowly from today.
Apart from starting to fill the water tank, there is nothing else to do today.
Chen Yun stayed in the house all day, reading and studying relevant information about greenhouse cultivation and soilless cultivation.
It was soon night, and Chen Yun sat on the sofa, watching the clock hanging on the wall slowly approach twelve o'clock.
[bite--!]
Electronic synthesizer sounded.
[Daily points settlement starts.]
[Settlement in progress…]
[Today's basic points: 24 points.]
[Today's Survival Assessment: Initial Base Construction: 500 points.]
[Settlement completed, current survival points balance: 684 points.]
"500 points." Chen Yun muttered to himself, "Today's settlement is even higher."
Without thinking any further, Chen Yun stood up and once again came to the garbage area on the second underground floor.
"With 684 points, we can complete the initial construction of the base facilities today."
Without hesitation, Chen Yun placed his hands on the garbage incinerator and sewage treatment plant in front of him.
Chapter 20 The base is initially formed
Will other incinerators and sewage treatment plants be used, and will the current incinerators and sewage treatment plants be comprehensively strengthened?
[Required points: 400.]
"yes."
As the progress bar on the light screen filled up, the three incinerators and two sewage treatment plants in front of us disappeared in an instant.
A silver-gray metal rectangle two meters wide, two meters high, and four meters long appeared in place.
On the front side of the cuboid, there is an independent one-meter square funnel-shaped feeding port, and inside the funnel are tightly interlocking heavy shredder blades.
The discharge port below the funnel feeding port is connected to the incinerator furnace entrance opened at the front end of the rectangular parallelepiped through a track nearly one meter wide.
After the garbage is put into the funnel-shaped feeding port, it is broken into small pieces by the shredder blades inside, and then sent into the rectangular incinerator furnace through the crawler belt.
Two thick exhaust pipes extend from the upper rear side of the machine, pointing directly to the top of the chamber in the garbage area.
There's a handle on the left side of the cuboid, which reveals a small chamber half a meter deep and high. A line of small characters is written on one side: "Ashes Collection Chamber." This is where the incinerated ashes are collected.
There is also a small handle on the right side, marked with the fuel tank.
Several wires and pipes extend from the back side, connecting to some cables and water pipe joints on the wall.
A little further away from the incinerator stands a huge silver-white metal cylinder, which is even larger than the water purification equipment in the water source area.
It is about three meters high and five meters in diameter.
The main water inlet on the left is connected to the seven pipes on the wall, and the water outlet on the right is connected to the remaining three pipes on the wall.
Domestic wastewater and sewage enter the sewage treatment plant through the water inlet, and after purification, flow into the farm area and other areas from the outlet for non-drinking purposes such as irrigation and flushing toilets.
The system light screen popped up in front of my eyes.
[Garbage Incinerator (Advanced): Maximum furnace temperature 3000 degrees Celsius, processing capacity 2 tons per hour, combustion efficiency 95%, exhaust gas purification rate 99%.]
[Sewage Treatment Tank (Advanced): Can withstand pH fluctuations ranging from 3-12...]
"It looks very powerful." Chen Yun looked at the equipment manual on the system panel. Every indicator was as good as that of professional equipment in professional places.
"Although some of the parameters are difficult to understand, the system's products are definitely top-notch."
Chen Yun turned around and walked to the door of the garbage area chamber. On the wall of the door was an LCD screen that was one meter long and about seventy to eighty centimeters wide. This was the operating panel of the incinerator and sewage treatment plant.
After studying it for a while and figuring out how to use it, Chen Yun left the garbage area and came to the open area in front of the stairs on the first floor.
Chen Yun used this place as his basement living room.
Standing in the center of the underground living room, Chen Yun looked around and prepared to start strengthening the last module of the construction base.
Air circulation system!
"I hope the points are enough." Chen Yun whispered to himself.
With a wave of his hand, two wall-mounted air conditioners and a floor-standing air conditioner appeared in the open space in front of him, as well as two steel ingots and some miscellaneous materials including activated carbon molecular sieve filter blocks and gas detection sensors.
Use your mind to summon the light curtain and click [Strengthen]
Silently recite in the mind: Special reinforcement, air circulation in the base.
[Should we consume the current air conditioner and other related materials to carry out special reinforcement of the base?]
[Strengthening direction: air circulation system. ]
[Required points: 250.]
"Just right..." Chen Yun murmured softly, and then said:
"yes."
The familiar progress bar, familiar blurry yet clear.
All the materials in front of him disappeared, and several thick, intersecting red light paths appeared on the dark gray walls, floor, and ceiling.
Chen Yun walked around the basement, carefully examining the red light path.
A control panel more than a foot long appeared on the wall at the entrance of each area.
On the other side of the distribution box at the entrance to the underground living room, there appeared a small gray-white metal door more than one meter high.
The thickest red light extends from here, then branches out, splitting into smaller red lights and continuing to extend, and then branches out again, connecting together red light spots that represent air outlets or exhaust vents.
The tiny red lights extended, then gathered in turn, and finally converged into a red light as thick as the initial thick red light. The gathered thick red light extended to the gray-white metal door.
The red light dimmed slightly, and yellow rays of light that gathered into a network lit up.
The yellow light is much smaller than the red light, but it also extends, splits, converges and returns from the gray-white door.
After Chen Yun roughly noted down these light lines, the red and yellow lights went out, the lines disappeared, and the veins of the entire air circulation system were deeply hidden in the dark gray walls, leaving only the delicate and concealed grille vents and control panels.
The system light screen popped up an explanation, and Chen Yun roughly understood this air circulation system.
The red light is the main ventilation duct, directly connected to the outside world.
The yellow light is an internal circulation pipeline network that is not connected to the outside world and only circulates within the base.
In extreme environments where the outside air is unsafe or the base needs to be completely closed, the system can switch to internal circulation mode.
The core of the two air circulation systems is the system-enhanced fresh air ventilation unit and air purification unit located inside the gray-white metal door.
You can use points to replace the filter element.
Chen Yun dispersed the system light screen with his mind, and looked up at the grille vents on the ceiling.
A very slight draft seemed to be circulating in the basement.
After a long sigh, Chen Yun returned to the old house on the ground.
The above-ground part of the house also changed. Grille vents appeared on the ceiling of each room, and smaller control panels also appeared at the door of the room.
Chen Yun Ge You lay on the sofa, looking at the dark gray wall in front of him, and said softly:
"Shelter, food, water, energy…"
"I have everything I need now…"
[bite--!]
A cold, mechanical synthesized sound rang in Chen Yun's mind.
[It has been detected that the survival base selected by the host has been preliminarily built.]
[The first stage of the mission "The Cornerstone of Survival" has been triggered.]
[Evaluating the host's current living base...]
[Evaluation in progress...]
Evaluation completed.
Mission 'Cornerstone of Survival' Phase 1 Assessment Level: B (Solid and secure, with generally complete equipment and no obvious vulnerabilities).
[Task reward: 3000 points.]
"My assessment level is only B. My rating for the previous mission of stockpiling supplies was A." After a brief moment of daze, Chen Yun fell into deep thought.
"It seems that there are still many flaws in the construction of my base. I can only wait and improve it slowly later.
"The points awarded for a B-rated mission are actually 3,000, which is more than even an A-rated mission for stockpiling supplies.
"Then how many A-levels are required for this mission? I wonder if the highest level is A or S or higher, and what the rewards are at that level.
"I need to build up my base well and strive to get an S rating in the next phase..."
After a long time, Chen Yun came back to his senses.
Attention turned to another task reward issued by the system.
[Survival Item Reward: Primary Drone (Basic Model) x 2.]
Two identical silver-gray drones hovered quietly in the system space.
In the system space, two identical drones were quietly hovering.
Around it are matching operating handles and VR glasses.
"It actually comes with VR glasses." Chen Yun waved his hand, and a silver-gray drone appeared on the coffee table in front of him, along with a handle and VR glasses of the same color.
The drone has a streamlined silver-gray matte paint scheme and is slightly larger than common light drones, measuring approximately 60 centimeters.
The structure is compact and precise, and the blades of the quadcopter are wide and thick with fine serrations.
There is a precision camera with a diameter of about one centimeter on the nose and tail, and two small mounting points on the belly.
The operating handle also has a silver-gray matte shell and looks similar to a game controller, but it is thicker than a game controller and feels smooth and silky to hold.
The controller is equipped with numerous buttons, multiple dials, and joysticks. In the center is a small, bright LED touch screen that displays flight parameters, thumbnails of the image transmission screen, and the status of the drone.
VR glasses are an integrated design that covers both eyes and is comfortable to wear.
"What a good stuff..." Chen Yun suppressed his inner excitement and picked up the handle. The handle felt heavy and full of texture.
After carefully studying the operating instructions on the system light screen and roughly memorizing the basic operating buttons on the drone handle, Chen Yun pressed the power button on the handle.
Buzz——
The small LED screen in the center of the handle lights up, and after the simple startup interface, it displays "Searching for devices... Connected: Drone-001".
Almost at the same time, the silver-gray drone in front of him made a slight buzzing sound, and several indicator lights on the fuselage lit up with a faint blue light, and the four-axis rotor slowly turned with almost no noise.
Chen Yun picked up the VR glasses on the coffee table and put them on his head. His eyes were covered by a deep darkness, and then a clear picture appeared in front of him.
Chen Yun saw himself sitting on the sofa, holding a silver-gray operating handle in his hand and wearing a slightly thick silver-gray VR glasses on his head.
In the upper left corner of the screen, the drone's flight parameters are displayed in real time: altitude, speed, battery level, coordinates, and distance.
"This is the real-time image and parameters captured by the camera in front of the drone."
Chen Yun tried to make a few movements, and the picture in his field of vision changed in real time, and there was no noticeable delay!
"No lag at all," Chen Yun exclaimed. He then gently flicked the left joystick. His image quickly panned to the left, the view smooth as a thread.
Stop the joystick and the details of the picture in front of you will be clear. Even in low light conditions, the picture is still bright and clear.
Chen Yun tried to switch the camera mode.
Press the switch button, and the world in front of you instantly turns into a clear green monochrome world. The shadows in the corners of the room and the texture on the wooden table are all visible clearly, just like daylight.
Press the switch button again, and the screen changes to color blocks representing different temperatures. Chen Yun himself appears as a bright orange-red human outline, and the surrounding walls are dark blue. The temperature difference is extremely clear.
"This is a reconnaissance artifact!" Chen Yun was a little excited. This drone can be used to scout the environment, monitor enemy movements, search for supplies, and provide nighttime warnings...
"I don't know if it can withstand the cold, the blizzards and extreme cold in the apocalypse."
Chen Yun piloted the drone towards the door. The door was open, and the drone flew out silently.
It was late at night, but the view was still clear.
Under Chen Yun's control, the drone climbed upwards and passed over the roof of his house. The view suddenly became wider and the entire Pingle Village was in sight.
Chen Yun hovered the drone dozens of meters above the yard, overlooking the entire village, and a sense of security arose spontaneously.
"With it, the area within a radius of dozens of kilometers is under my control." The frustration of being ambushed at night in the previous life was mostly dispelled at this moment.
Chen Yun began to test the performance of the drone. According to the data given in the system manual, the drone has a flight altitude of 4,000 meters, a range of 80 kilometers, and a maximum speed of 120 kilometers per hour. It can be charged normally or charged by consuming points.
The test flight lasted about half an hour. After Chen Yun became familiar with the various operating modes and functions, he reluctantly controlled the drone to return home.
The matte silver-gray drone flew through the entrance door and hovered steadily on the coffee table in front of Chen Yun. The rotors stopped rotating and the dim blue indicator light went out.
"If I had known there was such a reward, I wouldn't have bothered to personally explore the environment a few days ago." Chen Yun shook his head. "But I was given 50 points for exploring the environment that day, so it's not a loss."
Chen Yun waved his hand and took out another drone from the space. Two identical drones were displayed on the coffee table.
Looking at the two drones in front of him, Chen Yun fell into deep thought.
"Both drones have all the same functionality, which is a bit of an overflow.
"Why not have two planes each responsible for one part, 001 for reconnaissance and detection, and 002 for armed strikes.
"Strengthen 001 towards reconnaissance, and make 002 carry weapons like guns and bombs, strengthening it towards armed forces."
"We will start making the weapons and supplies needed for the enhancement tomorrow." Chen Yun made a plan, stood up, and looked at the time. It was already half past three.
"Let's rest first." Chen Yun turned and walked towards the bedroom.
…
The next morning, Chen Yun woke up early and went to the yard. He picked out a thick, long wooden stake that had not been split from the firewood piled in the corner.
Taking out tools such as knives, axes, saws, and planes, Chen Yun began to trim and chop the wooden stakes in front of him.
Soon, a crooked gunstock-shaped wooden stick appeared in Chen Yun's hand.
Chen Yun waved his hand and took out a high-pound compound bow that he had bought from a sporting goods store.
Putting the two together, Chen Yun called out the panel and silently said in his heart: Special strengthening and fusion!
[Do you want to strengthen the current item - compound bow, low-quality wooden stock model? ]
[Strengthening direction: integration and upgrading.]
[30 points are required for strengthening.]
"It's really good, yes." Chen Yun nodded vigorously, with anticipation in his eyes.
[Confirmed to enhance. Consumes 30 survival points.]
Under Chen Yun's gaze, the wooden stick and compound bow in front of him suddenly became blurred and changed shape in an instant.
A matte black compound crossbow appeared before my eyes. It was heavy, precise, and full of mechanical beauty!
The crossbow has tough lines, a compact structure, and is full of violent beauty. The taut black crossbow string and the gleaming arrow path demonstrate the deadly power of this weapon.
Chen Yun reached out and held the cold crossbow stock. It felt heavy, a bit heavier than his previous compound bow, but the center of gravity was well distributed, and the grip was very stable and comfortable.
Pull the power-loading lever, and with a crisp "click", the crossbow string is firmly hooked on the trigger hook.
Chen Yun waved his hand and took out a carbon fiber arrow, put it into the arrow path, and the arrow was firmly stuck on the quiver.
"Try the power!"
Chen Yun's heart was burning with anxiety. He returned to the basement living room, waved his hand and took out a half-inch thick steel plate, placed it against the wall, stood 20 meters away from the steel plate, raised his crossbow, and took aim.
Hold your breath and pull the trigger!
嘣――!
clang!!
First there was a low sound of the string, and Chen Yun only felt a slight recoil from the crossbow body, followed by a metal sound coming from the steel plate, accompanied by sparks flying!
Chen Yun's heart skipped a beat and he quickly ran over to check.
I saw that the arrow head penetrated the steel plate, and the arrow body was firmly embedded in the center of the steel plate!
Chen Yun gripped the arrow tail tightly and shook it left and right to pull the arrow out.
There were holes as thick as arrows on the steel plate. The arrow's tip was almost worn flat and the shaft was covered with cracks. A faint, inconspicuous white dot appeared on the wall that the steel plate was leaning against.
"Hiss..." Chen Yun looked at the scrapped arrow in his hand, then at the hole in the steel plate, and couldn't help but take a breath. "This power is really terrifying..."
This enhanced compound crossbow is probably just as powerful as a military-grade one. Combined with its near-silence, it's a must-have for home, travel, and even murder and arson!
"For now, I'll call you 'Compound Crossbow-001'."
Chen Yun gently stroked the cold crossbow shaft, his eyes gleaming with excitement. He seemed to have already seen the arrow piercing his enemy's chest.
"call--"
Taking a long breath and suppressing the excitement in his heart, Chen Yun put the compound crossbow in his hand back into the space and returned to the yard.
Looking at the knives, axes, saws, and planes in front of him, an idea popped up, "Can I make some other mechanical weapons that can store kinetic energy?"
At this moment, the phone in my pocket suddenly vibrated.
Chen Yun took out his cell phone and took a look.
It was Lin Wanwan's WeChat call request.
After hesitating for a moment, Chen Yun chose to answer the call.
"Brother Xiaoyun, are you home?" Lin Wanwan's lively voice came, "Come to my house for lunch today!"
Just as Chen Yun was about to refuse, Lin Wanwan's voice rang out again.
"I made dumplings today, stuffed with green onions and meat. I also made some mung bean soup and kept it in the refrigerator. Also, yesterday, Aunt Zhao from the village and I went to the mountains to pick a lot of mushrooms. Today, I'm going to make some chicken stew..."
Listening to Lin Wanwan's chattering, Chen Yun was lost in thought.
"Brother Xiaoyun, you must come!"
"Okay, thank you. I'll be there at noon." Chen Yun paused. "I just happen to have something I'd like to ask you, a top student majoring in agronomy, for advice."
"Okay! What's the matter?" Lin Wanwan asked with curiosity in her tone.
Chen Yun's lips curled up slightly, "I'll tell you at noon."
After hanging up the phone, Chen Yun called up the system screen. There were only a few days left in the countdown to doomsday, and it was time to start agricultural planting at the base.
Putting the phone back in his pocket, Chen Yun turned his attention back to the tools in front of him.
"Making a gun by hand is still very difficult." Chen Yun rubbed his chin, "and bullets are also difficult to make."
"How about trying to build a trebuchet first? See if you can upgrade it into a mortar or something."
Chen Yun started his manual work again.
Near noon, Chen Yun received another WeChat message from Lin Wanwan on his mobile phone, "Brother Xiaoyun, dinner is almost ready, come over quickly [smirk/]".
Chen Yun put down the messy pieces of wood in his hand and stood up.
After changing into a set of cleaner clothes, Chen Yun went outside the yard, locked the gate, and walked straight to the yard of Lin Wanwan's house not far away.
The aroma of food wafted from the yard, and the sound of spatulas colliding.
Bang bang.
Chen Yun raised his hand and knocked on the old iron gate in front of him.
"I'm coming!" Lin Wanwan's crisp voice rang out, and the courtyard door opened.
The girl was wearing a small floral apron, her long hair casually tied up, with beads of sweat on her forehead. She smiled at Chen Yun who was standing outside the door and said, "Brother Xiaoyun, come in quickly, the meal will be ready soon!"
Chen Yun walked into the courtyard, and the familiar smell of life hit him. The door to the main room was open, and several small dishes were already placed on the small square table.
"Brother Xiaoyun, please sit down first. It will be ready soon." Lin Wanwan walked quickly into the kitchen.
Chen Yun sat down at the square table. The dishes on the table looked delicious.
Smashed cucumber, scrambled eggs with tomatoes, stir-fried beans, sweet and sour pork, and a bowl of white and plump buns.
"Come here, come here!" Lin Wanwan walked out of the kitchen holding a pot of chicken stewed with mushrooms in a thick and oily sauce. She placed the pot in the middle of the square table and ran back to the kitchen.
Soon she came out with two bowls of still-cold mung bean soup, one placed in front of Chen Yun and the other placed opposite Chen Yun.
"Just took it out of the refrigerator." Lin Wanwan sat down opposite Chen Yun, "Let's eat."
Chen Yun thanked him and picked up his chopsticks.
The food tastes great. The sweet and sour pork is crispy on the outside and tender on the inside, the buns have thin skin and large fillings, the chicken stewed with mushrooms is salty and delicious, and the mung bean soup is cool and thirst-quenching.
Lin Wanwan's cooking skills are impeccable, which greatly comforted Chen Yun's stomach, which had been treated carelessly by him in the past few days.
The girl chattered about the village gossip of the past few days: whose dogs had a fight, whose cat had given birth, whose couple was arguing and threatening to divorce...
Chen Yun ate quietly, occasionally responding.
"Oh, right." Lin Wanwan seemed to suddenly remember something, "Brother Xiaoyun, what did you want to ask me on the phone?"
Chen Yun put down his chopsticks and spoke casually:
"Xiao Wan, you said before that you were majoring in agronomy?"
"Yes! I studied facility agriculture!" Lin Wanwan's eyes lit up and she became more energetic.
"From the Provincial Agricultural University! Even though I haven't graduated yet, I'm the top student in my major every semester! What's up? Brother Xiaoyun, are you planning on planting some vegetables? I'll help you!"
"It's not about starting a vegetable garden." Chen Yun shook his head. "Do you... know much about soilless cultivation?"
"Soilless cultivation?" Lin Wanwan's eyes lit up again. "That's very informative! This is the focus of our major! Brother Xiaoyun, why are you suddenly interested in this?"
Lin Wanwan looked at Chen Yun curiously, her face full of inquiry.
"Well... I resigned, so I have to find a way to make a living when I return to my hometown." Chen Yun made up a story.
"I see that our city now has special support policies in this area, so I want to learn more about soilless cultivation and greenhouse cultivation to see if there is any prospect for starting a business in this area."
"Starting a business? Soilless cultivation and greenhouses?" Lin Wanwan was even more surprised, and then became excited, "I think the prospects are pretty good!
"City dwellers are increasingly fond of green organic vegetables, and the prices are high. Although the cost isn't low, Brother Xiaoyun mentioned that with policy support, it's a good deal..."
Lin Wanwan instantly entered professional mode and didn't even bother to eat.
"I just have this idea, I don't understand the technology at all." Chen Yun showed a look of seeking advice.
"Xiao Wan, you're a professional in this field. Can you tell me more about it? For example, the specific operations of soilless cultivation..."
Lin Wanwan put down her chopsticks and sat up straight, a smile on her face, "No problem, Xiao Chen, please sit down, Teacher Lin's class is about to start!
"Let's first talk about the definition of soilless cultivation…
"Let's talk about the research background of soilless cultivation...
"Soilless culture substrate cultivation can be... Hydroponics technical points... Nutrient solution ratio... Lighting must be controlled...
"Humidity and temperature...pests and diseases..."
Lin Wanwan spoke with great enthusiasm and at a rapid pace. Chen Yun took notes seriously and combined it with the theoretical materials he had previously studied, and he managed to understand most of it.
"But Brother Xiaoyun." Lin Wanwan said with a dry mouth, drank a mouthful of soup, and calmed down a little.
"The initial investment costs are indeed quite high, such as the greenhouse, equipment, nutrient solution, electricity... all of which are considerable expenses. You also need to hire professional technicians, or learn a lot yourself, otherwise you can easily lose money!
Lin Wanwan asked seriously, "Brother Xiaoyun, have you really thought it through?"
"I'm considering it. I want to try it on a small scale in the early stages." Chen Yun responded vaguely.
"Brother Xiaoyun, if you really want to do it, feel free to contact me if you encounter any problems. I will be your technical consultant for free!" Lin Wanwan patted his chest and then lowered his voice with a hint of anticipation.
"Actually, I've wanted to build a small greenhouse for fun for a long time, but unfortunately I don't have the conditions."
Chen Yun looked at the girl in front of him and was silent for a moment. "Thank you, Xiaowan. I will definitely come to you if I need help."
After dinner, Chen Yun took the initiative to help clean up the dishes. This time, Lin Wanwan did not refuse. While washing the dishes, she occasionally added a few notes.
Before leaving, Lin Wanwan ran into the house, took out two thick books and stuffed them into Chen Yun's pockets.
"Brother Xiaoyun gives you this." Lin Wanwan said in a clear voice.
"Before the holiday, I thought I would study hard when I got home, so I brought a lot of books with me, but I ended up not having the heart to study at all.
"So, Brother Xiaoyun, you take a look at these two professional books first. I won't be using them for now. If you have any questions, feel free to ask me!"
Chen Yun took the heavy books, feeling a little complicated.
"Thanks."
After returning to his old house, Chen Yun went straight to the basement farm area, stood in front of a row of metal three-dimensional culture racks, waved his hand and took out several bags of cultivation medium, several bags of cabbage seeds and nutrient solution.
According to the method and process in the book and what Lin Wanwan just told him, spread the cultivation medium on the cultivation platform of the cultivation rack, carefully plant the cabbage seeds one by one into the cultivation medium, and then pour in nutrient solution and water.
Chen Yun only conducted experimental cultivation attempts on the second layer of the first row of shelves in the farm area. He planned to master the soilless cultivation technology before conducting large-scale planting.
After turning on the LED lights on the seeded layer of the three-dimensional culture rack and setting the lighting intensity and lighting time, Chen Yun breathed a sigh of relief, turned around and left the farm area and returned to the yard.
Next, just wait.
Back in the yard, Chen Yun came to the pile of knives, axes, saws and planes and continued his work on making a catapult by hand.
Time passed, the sun set, and the sky quickly darkened.
"It's already evening." Chen Yun looked at the broken pieces of wood in front of him and sighed.
"After an entire afternoon, I haven't even finished half of the base. Sigh..."
"Let's try something else..."
Without professional knowledge and experience, it is impossible to build complex machinery from scratch.
"Let's build it tomorrow." It was already completely dark at this time. Chen Yun put the rags in front of him back into the space, returned to the room, took out the two books that Lin Wanwan lent him, and began to read them carefully.
[bite--!]
A mechanical sound rang in my mind.
[Daily points settlement starts.]
[Settlement in progress…]
[Today's basic points: 24 points.]
[Today's Survival Assessment: Initial Base Construction: 300 points.]
[Initial Armament: 30 points.]
[Settlement completed, current survival points balance: 3358 points.]
"300 points. It seems that the points are not calculated based on the construction progress of the base, but based on the construction volume of the day." Chen Yun fell into thought.
"But more than 3,000 points are enough for a while..."
Without thinking any more, Chen Yun turned and went into the bedroom.
The next day, Chen Yun came to the open space in the center of the courtyard early, took out two empty wine bottles and a barrel of gasoline, and began to manufacture his new weapons.
Chen Yun gave up the route of hand-rubbing complex machinery and turned to more direct and crude consumables: Molotov cocktails and black powder.
Mix gasoline, engine oil and melted grease, pour it into a clean empty wine bottle, then add white sugar and potassium permanganate, and plug the bottle mouth with a cloth soaked in grease. A simple Molotov cocktail is ready.
Engine oil can slow down the combustion process and make it last longer, while grease can increase the adhesion of the fuel, making the flames after the explosion more intense. Sugar and potassium permanganate can increase the intensity of the explosion.
Call up the system panel. Spend 10 points and select [Enhance].
The simple Molotov cocktail in front of him was replaced by a ten-centimeter-diameter, orange-red ceramic sphere.
The system panel gives an introduction: a violent impact will cause explosion, the flame will stick and burn, the combustion temperature is above 1200 degrees Celsius, and the continuous burning time can reach more than 20 minutes.
Looking at the orange-red sphere in front of him, Chen Yun felt a little excited.
"If you mount this incendiary bomb on a drone, you can accurately strike the enemy from thirty kilometers away."
"Try making black powder..."
...
In the next few days, Chen Yun kept making weapons.
He drove a small truck and traveled back and forth to the county town twice, purchasing a large number of discarded empty beer bottles and canned glass bottles. He also bought several large bags of nitrogen-potassium compound fertilizer and sulfur tablets on the pretext of stocking up the farm.
The management in small towns is not as strict as that in big cities. There is no need for registration or reporting. The boss only collects money and does not care whether you use the fertilizers for fertilization or other purposes.
Gas stations still limit fuel purchases to 300 yuan, and passersby say electricity prices have also increased. Chen Yun is now certain that the authorities do have some information about the apocalypse and are gradually tightening resource control.
Back in the yard of the old house, Chen Yun continued to concentrate on making weapons.
The nitrogen and potassium fertilizers on the market have all been passivated. Chen Yun purified the crystals by dissolving them in water and then recrystallizing them, then crushed the crystals. He then ground the sulfur flakes into powder with the charcoal he had purchased during previous stockpiling, and mixed them according to proportion.
Finally, add sugar and potassium permanganate powder to make a coarse black powder.
Take out some black powder, compact it and put it into a glass canning jar, then fill it with small iron nails, broken glass shards and iron sand, tighten the lid and seal it with wax, and a simple fragmentation bomb is ready.
After the system's [enhancement] function, the homemade fragmentation bombs turned into dark green spherical fragmentation grenades with safety pins.
According to the instructions provided by the system, the killing radius of this fragmentation grenade is 20 meters and the lethal radius is 10 meters, which is quite powerful!
Chen Yun didn't test the two enhanced weapons. Firstly, they would be too noisy and dangerous, easily exposing him. Secondly, he was very confident in the system's output.
In a few days, Chen Yun produced a considerable number of incendiary bombs and fragmentation bombs, and stored them all in the space.
During this period, Chen Yun also bought a simulated toy gun, wanting to try whether it could be strengthened into a real thing. After all, in Chen Yun's view, as long as it has a mechanism, a spring, and a firing device, how can it not be considered a gun?
But Chen Yun failed, wasting 5 points, and the ordinary toy gun was enhanced into an exquisite and beautiful toy gun...
As for the inside of the base, the 100-ton water storage tank in the water source area is full of water, and the battery pack in the energy area is also fully charged.
The experimental planting area on the farm gave Chen Yun a headache. Even though he sowed and cared for the cabbage seeds strictly according to the steps in the book, the germination rate was only a little more than half.
The tender green buds that should have been densely packed are now sparsely distributed on the cultivation medium, looking very desolate.
The sprouted buds did not grow well under the LED lights. The leaves turned yellow, wilted and looked sickly. The seeds that did not germinate were like a stone sinking into the sea with no movement at all.
Chen Yun bravely asked Lin Wanwan indirectly on WeChat,
"Xiao Wan, what if... I mean, what if, we strictly control the environment according to the instructions in the book, but the germination rate of the seeds is not high and the growth is not good, what could be the reason?"
Lin Wanwan's call invitation popped up immediately, and the girl's voice was filled with surprise and excitement: "Brother Xiaoyun, have you started planting?"
Chen Yun was vague: "Well... I made a small rack, adjusted the parameters according to the book, and the seeds are new, but it doesn't grow very well."
Lin Wanwan pondered for a moment on the other end of the line. "Maybe the substrate isn't good? Or maybe the seeds are infected, or maybe there's an imbalance of trace elements... Brother Xiaoyun, try disinfecting the seeds..."
Lin Wanwan gave a series of reasons and suggestions, and Chen Yun replanted according to her instructions, but the results did not improve much. The germination rate was still only more than half, and the seedlings that grew were still not very good.
Chen Yun checked the environmental parameters countless times, and the temperature, humidity, light, and nutrient solution were all normal. He had no choice but to blame it on the quality of the seeds themselves.
So Chen Yun went to another seed wholesale store in the county again and bought a large number of new seeds, but the germination rate of the new seeds was still not high.
Chen Yun was really at his wit's end and could only put the matter aside for the time being, thinking of trying again after he had completely learned it.
During this period, Lin Wanwan came twice. Once she brought some fresh vegetables, and another time she wanted to see Chen Yun's experimental soilless cultivation, but was rejected by Chen Yun on the grounds that the place was too small and too messy and the equipment was still being debugged.
Although Lin Wanwan was a little disappointed, she soon smiled again.
"Okay, okay, I won't look at Boss Chen's confidential project for now, but if you have any questions, you can always call your teacher Wanwan!"
After seeing Lin Wanwan off, Chen Yun returned to the underground farm area and looked at the half-dead seedlings, and sighed deeply.
As time goes by, a few days pass by quickly.
...
July 15th, 7:32 am.
[Countdown to the extreme cold apocalypse: 0 days, 16 hours, 27 minutes, and 19 seconds.]
"There's only one day left until the end of the world."
Chen Yun looked at the countdown that kept jumping on the system screen and breathed a sigh of relief.
The daily points calculation these days is roughly between 150 and 200. Excluding the points consumed in weapons manufacturing during this period, Chen Yun now has 3,800 points in his hand, which is quite abundant.
After turning off the light curtain, Chen Yun stood up and walked out of the yard. He was ready to go to the county town one last time.
After walking out of the yard and locking the gate, Chen Yun walked towards the small truck parked in the corner.
There was still some money left in the card, and it would be a waste to keep it, so Chen Yun planned to spend it all in the county town on the last day before the end of the world.
Just as I opened the car door, the old door of Lin Wanwan's house not far away creaked open.
Lin Wanwan came out carrying a canvas bag. When she saw Chen Yun opening the car door and preparing to get in, her eyes lit up and she trotted over.
"Good morning, Brother Xiaoyun! Are you getting ready to go out?" Lin Wanwan, wearing a white shirt and a long black skirt, asked, "Are you going to the county?"
"Yeah." Chen Yun nodded.
"Great!" Lin Wanwan smiled. "Can you give me a ride? I also want to go to the county to buy some things and daily necessities."
"Okay, let's go." Chen Yun did not refuse. After all, he was not going to do anything shameful in the county this time.
"Thank you, Brother Xiaoyun!"
The car drove out of Pingle Village and merged into the road leading to the county town.
The car window was open and a breeze blew in, bringing a slight coolness.
"Oh, right, Brother Xiaoyun." Lin Wanwan, sitting in the passenger seat, turned to look at Chen Yun. "Have you checked the weather forecast? The temperature might drop in the next few days. They say a cold front from the north is moving south, and there's going to be a cold wave."
"Well, I didn't see it." Chen Yun shook his head, but his hands tightened around the steering wheel, thinking in his heart:
Cold wave… Have the authorities already used this relatively mild term to foreshadow the end of the world? But isn't it a little too late to start now? Or perhaps the authorities don't have a firm grasp on the exact date of the doomsday, and even the approximate time is subject to significant error…
"I don't know if it's true or not. It's really strange that there is a cold wave in the dog days of summer." Lin Wanwan said with a bit of confusion.
"But it would be nice if the temperature could drop. It's been scorching hot these past few days. Brother Xiaoyun, how much do you think the temperature will drop this time?"
Chen Yun withdrew his thoughts and turned to glance at Lin Wanwan. "It should drop a lot. Maybe it will turn into winter."
"That's not that exaggerated." Lin Wanwan responded with a smile, "But I hope it's not too cold, just a little bit of heat would be nice.
"I only brought a few summer clothes with me this time. My thicker clothes are all at school. If winter really turns into winter suddenly, I'm probably going to freeze to death."
Chen Yun was silent for a moment. "This time when we go to the county town, we can buy two more thick clothes, just in case."
"Well, my parents called me this morning and said they heard the temperature would drop in the next few days, and they kept nagging me to prepare two thick layers of clothing." Lin Wanwan said with a smile.
"I'm going to the county today to buy one, just as a way to buy new clothes for winter. I don't know if clothing stores still sell winter clothes at this time of year."
"It's been so long, uncle and auntie haven't come back yet?" Chen Yun asked casually, "They are so relieved to let you stay home alone."
Hearing this, Lin Wanwan showed a helpless expression on her face.
"In recent days, several flights from Heilongjiang to our province have been suspended, and several high-speed train services have also been cancelled. The few remaining services are either sold out or have extremely high ticket prices.
"They can't come back even if they want to, so they can only wait for a while before coming back.
"Besides, there's nothing to worry about. I'm already such a grown-up."
Chen Yun nodded. "I heard you say that your uncle and aunt are living with your relatives?"
"Yes, my cousin's house." Lin Wanwan opened the car window a little lower, "When I called my parents this morning, my cousin urged me to go over to his place, saying it was so much fun.
"But there are no flights or high-speed trains, so I can't go there even if I want to." Lin Wanwan spread her hands.
"But it's also nice to be at home. Every day I plant vegetables, water flowers, play with my phone, and go for a walk in the village after dinner, petting cats and dogs. It's so fun."
Chen Yun glanced at the girl's carefree profile in the rearview mirror and said softly:
"Buy more daily necessities, including food and drinks. My car can hold a lot anyway. If a cold wave really hits in a couple of days, it might be inconvenient to come to the county. I'd like to stock up now."
"Yeah, I came to the county town this time just to buy daily necessities." Lin Wanwan was stunned, then laughed.
"We are running out of salt and snacks at home, so I plan to buy some snacks, cut some fresh meat, and buy some chicken, fish, and other things.
"But Brother Xiaoyun, you're right. It's time to stock up. I'll buy a little more today, and I'll trouble you when the time comes."
Chen Yun nodded and said nothing more.
The car stopped at the entrance of the county town's commercial street. Lin Wanwan jumped out of the car and waved to Chen Yun.
"Thanks, Brother Xiaoyun. I'm going to go shopping. Just call me when you're done."
"Yeah." Chen Yun nodded.
Watching Lin Wanwan's figure disappear into the crowd, Chen Yun turned the car around and drove towards the electronics city at the other end of the county.
In the electronics city and the flea market, Chen Yun collected several radios of different models, several walkie-talkies and several sets of cameras.
He found several boxes of miscellaneous electronic products such as circuit boards, chips, sensors, and even a small radio.
There are also several boxes of old hard drives, graphics cards, CPUs and other computer accessories.
When I stockpiled goods before, I focused on necessary items such as food, medicine, and energy, and bought very few electronic devices.
Now while there is still money in the card, buy these electronic devices, they may be useful in the future.
The purchase is complete, it's still early.
Chen Yun drove the car slowly through the main road of the county town.
The sun was blazing, traffic was surging, and pedestrians were hurrying by. Loud music played from shops along the street, lines formed in front of the milk tea shop, and smoke rose from the snack stalls.
Everything was the same as usual, with no sign of the end of the world.
"The final peace..." Chen Yun was silent in his heart.
The ordinary street scene before my eyes may never appear again after tonight.
With a sigh, Chen Yun looked away. He took out his cell phone and called Lin Wanwan.
"Hello, Brother Xiaoyun, are you done?" A crisp voice came from the other end of the phone, "I'm at the entrance of the department store, I have a lot of things..."
Chen Yun drove over and saw several bulging bags piled at Lin Wanwan's feet.
Chen Yun stopped the car and helped her move the bags into the truck. Each bag was very heavy and filled with snacks, biscuits, chocolate... as well as salt, sugar, fresh pork, frozen chicken and several processed fish.
After closing the carriage, Chen Yun and Lin Wanwan got on the train.
"Hehe~ I did a big shopping today." Lin Wanwan's face was filled with smiles. "I bought a lot of food, drinks, and other daily necessities. I also bought two thick down jackets..."
The car started and drove away from the bustling county town.
"Brother Xiaoyun, how is your soilless cultivation experiment going now?" Lin Wanwan looked at Chen Yun and asked curiously, "Have they sprouted? How are they growing?"
Chen Yun looked ahead, the sparse seedlings on the farm flashing through his mind. "Well, they're growing well."
"Really?" Lin Wanwan was delighted. "It seems like you're doing pretty well. When your confidential project is released, let me have a look!"
"Let's talk about it later." Chen Yun responded vaguely.
The car quickly returned to Pingle Village and stopped at the gate of Lin Wanwan's house.
Chen Yun got out of the car, opened the cargo compartment, and helped Lin Wanwan carry all the things back into the house.
"Brother Xiaoyun, thank you so much today!" Lin Wanwan smiled brightly.
"Come to my house for lunch tomorrow! I bought so much food today, let's have a good meal tomorrow! I'll make you braised pork, steamed fish, and shredded chicken..."
"Tomorrow..." Chen Yun paused, "Let's talk about it tomorrow. I'm going back first."
"Okay then! I'll call you tomorrow morning." The girl still smiled.
Chen Yun turned and left, walking towards his own yard.
After returning to the house, Chen Yun did not rest but went straight to the basement.
He inspected the underground floor, the water source area, the energy area, the farm area, and the garbage area in turn. He then immersed himself in the system space, carefully counting every item of supplies: fuel, food, medicine, weapons...
After confirming that there were no omissions, Chen Yun returned to the old house on the ground floor and sat down on the sofa.
The system light curtain was summoned, and a line of small words kept jumping above the light curtain:
[Countdown to the extreme cold apocalypse: 0 days, 12 hours, 11 minutes, and 10 seconds.]
[Countdown to the extreme cold apocalypse: 0 days, 12 hours, 11 minutes, and 9 seconds.]
…
The wall clock ticked away, and the seconds passed. Chen Yun sat quietly on the sofa, watching the countdown on the screen flicker and jump.
Outside the window, the sun is shining brightly.
Outside the window, the setting sun is slanting.
Outside the window, dusk is falling.
Outside the window, the bright moon hangs high in the sky.
…
[Countdown to the extreme cold apocalypse: 0 days, 0 hours, 1 minute, and 19 seconds.]
[Countdown to the extreme cold apocalypse: 0 days, 0 hours, 0 minutes, and 10 seconds.]
9…8…7...3…2…1…
