Third person pov
North Blue year 1516 (6 years before the start of canon)
A young man dressed in rags, is unconscious in the middle of a deserted island, surrounded by the remains from a ship where he was having a great evening, but now only the wreckage remains, as he slowly wakes up, confused and lost, he looks around and he slowly recalls what happened.
Ars Pov
Looking around at the remains of the broken ship, Ars remembered his previous night, he was originally enjoying a trip on his small boat until he spotted a cruise ship, the sailors on the ship also saw him and when he approached they happily invited him on, later on he met an interesting old man which had bought a island, and intended to govern a small village there, as they were talking and drinking, they heard canon fire, the trip on cruise ship was going well until today.
Now they were getting attacked by pirates, the pirates attacked with their cannons from range, and while the cruise ship wasn't that well equipped for combat it still had cannons, which the sailors used to fire back. As he was going to hide the ship got hit and he got caught in the explosion and lost consciousness.
When he woke up, he was surrounded by sand, rocks and wreckage, he thanked his luck for still being alive, as he looked around, and by what was in the surroundings he could pretty much confirm that the cruise ship ended up sinking.
He closed his eyes, and cursed his luck in his previous life, he was just going for a short walk, in a well know trail, as he was walking, he looked up and saw a plane crashing down, he started running and managed to dodge the plane, but just as he was feeling lucky, he looks up again, just to see a meteorite falling right on top of him… Just as everything went black, he woke up in a different world, at the very best he was in a world he knew. At first he didn't know it, but then he saw a wanted poster from whitebeard and with the information he got he realized he was in the one piece world.
After he managed to locate himself and after investigating he discovered, when he arrived according to the timeline of the canon.
After a while of messing around to see if he had any special golden finger, he realized that he had 2 abilities.
The first of them was a pocket dimension that contained a laboratory, it had different utensils, the ones Ars managed to understand their main function were, a gigantic tube where you easily could put a giant, and in it DNA of the individual could be modified, the DNA could be evolved in any direction Ars decided, other utensil, was a computer permanently researching various possibles ways to try to enhance DNA sometimes it worked sometimes it didn't, besides the computer you could see a big group of containers, that you could use to collect samples to accelerate the research or add new possible ways to evolve any individual, for example the blood sample from someone who has a akuma no mi or different races, then those samples would be analysed on the computer and once done he could further optimize them, to better fit the new abilities on himself.
The second was a compass to project GAIA. This project was created in the past as a contingency plan in case the ancient weapons ended up destroying the world, this ancient machine worked by collecting and teleporting materials across the universe, and then creating a new planet in a nearby star system, in this case would be same same system they currently resided, but it would be located in the opposite side of the sun, the machine could control the planet size, the shape and environment, and the machine would control the planet distance from the sun, in a way that the planet was a perfect distance from the sun, so the planet could have life.
He tried to search for project GAIA in the surroundings of the place where he woke up but failed to find anything on the island, but he did find a small community with around 50 members, since the compass pointed away from the island, he decided to try and leave the island.
He went around and tried to find someone with boats to try to find the price for one, but after searching for a while, he discovered that there was no one like that on the island. After asking around he got information about an old small ship that could be easily used by just one person, but the problem was it was damaged and it could not sail and there wasn't anyone who could fix it.
Without a choice he reluctantly stayed on the island while learning how to fix a ship, from books about shipwright. While he stayed he worked as an assistant at a clinic, where he managed to get himself a few blood samples from the island inhabitants that came there with injuries.
While introducing the blood samples he discovered he could give the research a direction to go for, instead of going random. It could research a huge range of topics, from basic body enhancements like more strength or endurance to super powers, but the harder the research direction, the more time it would take to get results, the only exception would be if samples with rare characteristics that corresponded with the desired direction would be inserted by Ars, for example if he was researching super strength and managed to get a sample from someone with super strength in their DNA, the research time would be lowered, but at the same time, another thing he noticed was that if he introduced the blood of a normal person, the effect on a research about most specific topics would be minimal.
On the island, outside work hours he rarely interacted with other people, and after a few months he finally finished repairing the ship enough, and the ship was finally usable. On the same day he bought some provisions, said goodbye to the doctor and embarked on his journey.
After navigating for close to a year, it takes him back to the present on the deserted island. Having survived with a few wounds, his body wasn't anything special yet but it was just slightly above average in most aspects with the exception of stamina, because he didn't have many opportunities to train it on the ship.
According to the information he got from his file on the computer, he learned that he was just above average, reading the information, it showed:
Name: Ars nautical
Age: 16
Body: 1.2 ( i'm gonna assume the normal human in one piece is capable of lifting 100 kg, due to having mixed opinions and not being sure what is the real average in one piece, and that corresponds to a value of 1)
Mind: 1.1 (average would be 70 Iq, which would be a value of one)
Willpower:1
Super Powers: N/a
It was a simple set of information, but it helped. with it he could realize he had a better body by 20% compared to your average person, and he was happy about it.
He assumed there would be other people alive but separated throughout the island, so he went to search.
After searching the coast he managed to find 11 others that were still alive, he helped them with gathering materials. While he was searching for those, he managed to find a medical crate that was in good condition with the materials inside mainly intact, it wasn't too far from the camp, and he took it back to the makeshift camp.
Ars pov end…
Ars, using the medical supplies and his experience in the clinic, helped with the wounds of others and managed to get some blood samples while he was at it.
Two surviving sailors went to hunt, and managed to come back with some meat, when everyone was eating, everyone was also talking with each other, trying to come up with ways to leave the island and go back to their lives, at least those who could.
One older female that was silent until now, clapped her hands to call attention to her, everyone froze confused and were now looking at her, and she shared some information with them.
"You don't need to worry about getting out of the island, some of the passengers had powerful backgrounds, and there will be marines coming to try to find them soon enough. "
She seemed a little down but everyone here with the exception of Ars had lost someone so it wasnt that surprising. But at the same time that information brought some relief to everyone.
With that relief everybody started to make plans for the next few days on the island. Ars was planning to gather some wood to make a makeshift shelter, and after that he would try to get some items from the wreckage that looked like they would be easily sold, so later he went around the island searching for items to sell later.
The next few days passed quickly and when the marines appeared on the island Ars had managed to get 14 swords and some jewelry.
The marines that just arrived started checking the people who were still alive, and when they reached Ars, realising he wasn't on the list the marine in charge suspiciously asked " Who are you? And how did you get here?".
The marines were obviously thinking that he was a pirate, and to quickly clear the confusion, Ars calmly answered "I was traveling between islands with a small ship, when the sailors of the cruise spotted me and invited me to board until the next island. If you don't believe me you can ask the two surviving sailors. "
The marine that was in charge called over another marine and whispered something, that marine left for a few minutes and then returned and whispered back. "You can go, your story was verified." After that the marines left him alone. After everything was done, the marine vessel sailed in the direction of the closest big city, which was a half day in favorable weather conditions.
On the way there, Ars just stayed in his designated room and thought about the best place to get the most money out of his items. Once they were on the island, he quickly went to a weapon store. "Hi! I would like to sell these swords."
" Hello! You can put them on the counter so i can examine them " the shopkeeper said, and after Ars finished putting them in place, the shopkeeper started working,and after a few, minutes he answered " Well i can offer you 30.000 Berries for each, for a total of 420.000, would that be okay with you?"Ars accepted with a nod and then left for the jewelry shop, there he repeated the process, but managed to get more money, around 600.000 berries.
After he left the store, he noticed he was being followed by some thugs and started running, it looked like they thought Ars was easy prey, after a few turns through the different streets they ended near the beach. Ars picked up some sand from the ground and started planning his next actions.
