I Became Luffy's Navy Brother

The master of holding pills in his previous life died due to a mission, and was reborn as the Pirate King, becoming Garp's eldest grandson and Luffy's brother. As Louis, who grew up in China, for Garp's wish, he became a navy man and became the navy's troublemaker, disrupting the plot and disrupting everything. In this life, he will protect Luffy and Ace and will not let history repeat itself. Garp: "Louis, he deserves to be the grandson of the old man, and he will give him a good face." Warring States: "Louis, your family is nothing but troublemakers. You are involved in everything. Do you want to piss me off to death?" He has no interest in ending the pirate era started by Roger, but he can disrupt it all. This novel and its characters are purely fictitious.
