The following are a few recommendations for One Piece novels about becoming stronger together with Luffy: - One Piece: Tricking Luffy into joining the army, changing the plot to become stronger: The protagonist transmigrated to the world of One Piece, changed Luffy's ambition, and worked hard to become a navy general. Changing the plot would make him stronger. - [One Piece: All Members System]: The protagonist awakened the system and captured the wild Rolonuo. Sauron, become a member of the Grass Hat Pirates and let the world feel fear! - " One Piece Begins with Kokyu-ho ": The main character receives a witness system in One Piece's world, draws the strongest Kokyu-ho, becomes a dancer in the Grass Hat Pirates, and carries out the world's greatest adventure.
