I plan to do something like this some power are permanent but need to be trained (like chakra from Naruto univers, haki from one piece, and Ki from DB/DBZ) because they are from the body of the user,


    but everything that comes from an universe like energy in the air (wuxia, xanxia, or mana, etc...) will be stocked and usable but limited impossible to regenerate except if in the world from where the energy originate or a similar energy is in the current world... If you spot this story on Amazon, know that it has been stolen. Report the violation.


    As for the appearance of the MC x Weapon i will see the result of the poll
