One Piece: Invincible World System

Luo Feng traveled to the world of One Piece with the Under One Person System. The former captain of CP0 recognized him as his younger brother. Zefa lived next door to him and was his instructor. Together with Garp Kizaru, he was also known as the three treasures of the navy. Is this the end? No, this is just the beginning. He tortured Doflamingo, chopped off Blackbeard, scared off Whitebeard with the sound of Uncle Ape, fed Charlotte Lingling, and beat the Five Emperors of the New World. There are still a lot of things I haven't finished yet. I'm trying my best to write them and you can read them slowly... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
