Comments of chapter undefined of One piece: The Fist of Justice

Reading - Maybe because he is just a kid now he is so chaotic.

Will he meet luffy?

Why do the authors who make One Piece Fan-Fic always want to use the meaning of the real world in the world of One Piece, that is something completely meaningless...I mean, the body physique of the people in One Piece is completely superior to the condition of the people in the real world, why do they do that outside? I don't understand

Crazy

Great chapter

is the mc a native or a reincarnation, is he an au?

Harém?
