So the lead only had one arm and I think he learned to fight with sword. But everyone only liked the other cousin in the main family or something and they bullied them very hard idk if he had to do something with his missing arm anymore. And before his reincarnation he had like a fight with the cousin and idk if he won or lost but later on the cousin did capture him and killed him.
THEN he kinda reincarnated in a boys body (dont know the timeline tho) who was very weak and couldnt use magic or something. But the body had chi or something and no one knew?? Maybe mixing up 2 isekais at this point. But yeah the boy he went into was like a ghost then and they made a deal.
OMG if someone finds it that would be a miracle with this description
https://www.mangago.zone/read-manga/standard_of_reincarnation/ found it nevermind. ... whoever wrote all my shit sorry XD And damn it was a webtoon.
The whole plot is that he can cheat and the admins say "freedom" and just accept everything. And in the beginning it says he is the top Player in various games but still only cheats without using any skill. Its a trashy Story with trashy Elements. Gonna drop this (my opinion)
