Transmigrate into the Blackbeard Conflict: The Race for the Great Treasure

Any Good One Piece Fanfiction? Lately, I’ve Only Found Two Worth Reading

Looking for books similar to "One Piece: The World's Most Evil Criminal, Slaughtering the Celestial Dragons". There's also one about Experimental Subject 88, and another with a title starting with Tom... something. Those two were decent. In the others, either the protagonist is written as an idiot or the story deliberately smears Nami and Robin just to add them to the harem.

Navy, No Goody-Two-Shoes, Decisive and Ruthless, Admiral, Doesn't Fawn Over the D Clan, Got It?

Looking for books like "The Navy Takes Down Monsters".

One Piece + System, with a Protagonist from the Previous Era
