Spikes pierce through some people, and the man who created them walks calmly. He looks around and notices that only three people remain. He says he will let one of them run for a few seconds, but the others will stay.
"Only one of you will live; the others will die like vermin. Choose who," he said seriously.
Before the others can choose one of them, the other one has already run away. The two turn around and realize what has happened, and with tears in their eyes, they wonder why. Spikes form behind them, piercing them.
"Well, it looks like you've chosen one. Well, it's time to hunt," he says, starting to chase after the one who ran away.
The man is running down a hallway, fearing for his life, not wanting to die, just fleeing from his destiny.
"No, I don't want to die yet, I still have so much I want to try, I don't like the idea of leaving," said the man, running even faster.
A door is in front of him and he thinks he's saved. He stops, turns the handle, and opens it, but behind the door there is spilled blood, and before he realizes it, that blood takes the form of a spike and pierces him, killing him instantly.
"Did you really think it would be that easy to escape me? I use my blood fusion ability, using my blood as a flow to turn it into spikes that kill my targets," he said, relaxed and sighing.
Suddenly, he feels his body start to feel strange, and he feels his blood wanting to burst, so he looks back and sees the figure of a girl, she is just standing there watching.
The man quickly moved away, walking far enough to calm down, then asked her name.
"Who the hell are you? What's your name?" he said tensely. "Well, I can't tell you my name, but they know me as Eight."
"I see, you're the eighth mercenary. Now this is interesting. What's your name, now that I've told you mine?" said Eight, smiling.
"My name is Kain Trox, but it doesn't matter, you won't remember it for long," he said, attacking. "I see, you're the guy with the spike ability. This will be easy."
Kain scratches his hand with his nails, drawing blood, and throws drops of blood at Ocho, who dodges them but doesn't understand why. The drops fall and turn into jets of blood, which take the shape of beaks. Ocho dodges them.
"I see your ability is based on using specific points to form them," said Ocho, intrigued. "Damn, I dodged it, but I don't know why. When I was there, I felt sick. Oh, I get it, it must be one of those techniques based on manipulating someone else's blood," said Kain.
Eight approaches, attacking, but Kain moves away, putting distance between them. "If not, people like that are limited to a range of meters, since if the technique is strong, there must be an adequate price to pay or a disadvantage. There is no strong skill unless there is something that makes it so. I imagine it only works within a certain range from here, but I don't know how many meters its power reaches," said Kain, agitated.
Suddenly, footsteps are heard. Eight is confused because she thought she killed everyone in the building, but Kain reveals that in reality, there are only a few upstairs, while down here there are many. Many people come out and surround Eight, but she uses her ability and kills several of those surrounding her.
Kain says that he only killed half of them within a few meters, surrounding the corpses and seeing that the others behind them were still alive, but being careful.
"So, calculating the area and the dead bodies nearby, that means his ability works in an area of 40 meters, so I just have to keep my distance and when there's an opening, I'll take advantage of it to get closer," said Kain, analyzing the situation.
But out of nowhere, some men appear walking and 10 of them fall lifeless, their skin gray, as if their hearts had stopped pumping, and someone appears.
"Wow, I thought they sent me alone. I didn't expect to see you here, Nine," said Eight, impressed to see him here.
"They sent me because they knew you would trust your opponent, because you can never be serious once in your life," said Nine with a sigh.
Kain realizes that he is now in serious trouble with another top mercenary, but unlike the rest, Nine is better known for his blood fusion ability, which allows his blood to boil, and he can also boil the hearts of people with other people's blood.
"Damn, that's why blood fusion guys are hard to understand because of the abilities they develop," Kain said angrily.
Narrator: To better understand this concept of blood fusion, we must go back a few moments. As you know, during the war, the weapons and bombs used caused an outbreak of a virus that was named VentX. There were cures, but they only delayed the effect. However, a new cure was found that delayed the effects even further, but it caused the bloodstream, the cure, and the virus to fuse together in the bloodstream, said the narrator.
The narrator continues, "All of this led to it being called blood fusion, but the abilities it granted were linked to the blood, and the abilities varied depending on many factors. For example, there are people whose abilities could be developed through trauma, convenience, depression, facilitation, support, hatred, courage, experiences, and finally, tastes. all of them linked to human feelings. Only one of them can be the result. The abilities depend greatly on which emotion is strongest in that person, ultimately manifesting their blood ability, said the narrator.
The narrator continues with the explanation: "For example, there are some people in many of these cases. For example: Kain's ability is called 'peaks of sin.' He uses his own blood for the peaks, generating them in specific places where his blood is, and the drops that come together create a peak to kill his victim. This depends on where the blood is, if it is within his range to control it. The reason for his ability comes from the fact that he always found hidden traps useful, and the ones he used most were spikes, and with that he developed his ability based on his ease.
—Other abilities are eight and nine. First, eight, his ability is called foreign blood manipulation, which allows him to interact with the blood of others, causing it to accumulate and explode inside them or end up affecting their organs. Second, nine, his ability is called cauldron of life, his blood boils, causing damage to those who interact with it or have his blood on them.
—But also, even if it's not said, there are also blood contracts. These are necessary because the human body only has between 4 and 6 liters of blood. Using too much blood in your abilities causes extreme fatigue, acute anemia, fainting, and internal bleeding. That is why advanced users develop techniques such as recirculation, microextraction, or regenerative serum. The techniques and abilities that can be created with blood are very limited.
That is why there are blood contracts. If you have a powerful skill, it can have a disadvantage in terms of consumption, but blood contracts are different. In these, you can place a condition on your body, but that condition must also have a disadvantage, because everything has to be kept in balance. Otherwise, you will die immediately if you overlook the conditions of your human body.
—In fact, don't tell anyone, but the reason Nine can also boil the hearts of others is because of his blood contract, and the condition he set is that he can only use that technique, his ability, if he is at the same rhythm as the heartbeat to achieve it. Therefore, he has to hear the heartbeat to know, but it is also difficult if there are several people, he can concentrate on only a few, But if he has to eliminate several, he has to concentrate hard to use his technique on all of them at once. To activate it, he just has to touch them and that's it.
"And that's the end of the details. It's not known for sure how Eight and Nine got those abilities. Not much is known about their past, but maybe it will be discovered soon," said the narrator, ending his explanation.
Returning to Kain, he decides to attack, piercing his arms with his thumbs and then stretching the wound, causing blood to spurt out and spread throughout the room. The blood then takes the form of spikes and attacks, but Eight and Nine dodge them.
Then more people arrive to attack. "Hey, you can't kill the others," said Eight to Nine. "We're not counting heartbeats at once. I'll need time, so just fight normally," said Nine, taking some knives out of his pocket.
With this, Nine cuts the vital points of the other people, killing several, and Eight gets rid of the rest. With this, only Kain remains, and he faces them.
The fight is long and complicated due to Kain's skill, and he uses more blood, but at one point in the battle, Eight gets very close and is within range, and we see how Kain's arm begins to deform to explode and will reach his body.
But he cuts off his own arm, doing so because he discovered that the ability activates in a specific place of her choosing, and then moves to another part of the body, taking advantage of the blood spurting from his severed arm to create a little something that will kill her.
We see that Eight blocks it, but it pierces the palm of his left hand. Kain smiles, believing he has won, but it was all a trick. Taking advantage of this, Eight moves closer, jumping over his hand, but he gets closer and manages to use his ability, and half of Kain's face and other parts explode.
"Well, that was enough, I won," said Eight.
But Kain was still alive and refusing to be killed, he uses his ability inside himself, pulling out several spikes and attacking. Eight and Nine manage to dodge him in time, but when they recover, they realize that Kain killed himself just by using his ability inside himself instead of using it outside with his blood.
In the end, they just open the vault and take out the object, which is a mini statue of Anubis from centuries ago.
"It could be worth a lot at auction. Now I understand why they hired a top agent," said Eight, looking at the object. "That's why they don't trust each other much if the object is important," said Nine.
And with that, they return to base, deliver the object, the buyer transfers the 30 million and Sev to them, then Eight wonders where the others are.
He asks the receptionist, "Hey, where are Five and Ten?" said Eight. "Well, Five is on a mission to gather information, and you know how he is, he'll torture anyone until they give it to him. Ten is on a mission to infiltrate a party with Six. They have to kill a biology professor who has a drug to increase blood efficiency, but it also has its consequences and problems. Since no one else wanted to do it, they were hired for that mission," she replied.
"Well, what can you do? I just hope they didn't put Five on the mission, knowing his abilities. He could kill several recruits if he uses them," said Eight, thinking. "Well, all we can do is wait or hope that someone else hires us," said Nine, going to sit on a sofa.
Elsewhere, a man tied up and suspended from above by a rope begs for his life, and we see a young man in a hood covering his mouth and showing half of his face, with a skull on his mask. He is holding the rope, and below we see a pool filled with acid.
"Please spare my life," said the man. "Then tell me the information about a certain Vionerx project," said the boy.
"No, I can't. It's impossible to tell you. I'll never do it, even if you threaten me," said the man. "Well, okay, find someone else," said the boy, letting go of the rope.
The man falls into the acid and suffers until he dies, then the boy leaves and someone calls him.
Being a recruit of the organization, "Sir, Five has finished extracting the information," said the recruit. "No, in the end he didn't tell me anything. Find others and capture them and bring them here," said Nine.
Everyone goes to search. Five thinks this will take a long time.
Elsewhere, at a party, a man and a woman are there as infiltrators.
"Well, Six, we have to start searching," said the man. "I know how. Mission Ten," said the woman.
And they scatter to search for the man.
