100+ chapters of water and no proper story building. I think author only want to fill chapter content and there is something wrong with either the novel title or system, in normal double crossing novels MC goes to different worlds personally here seperate identity is created and MC even became double jinchuriki only to go to One Piece world to get second devil fruit i.e Goro Goro no mi. If he wants to be jinchuriki so badly he could have directly become 10 tailed one.
