On the Eve of the War, Join the Navy as an Undercover Agent!

Zuowu traveled to the world of One Piece and became the captain of the 17th division of the Whitebeard Pirates, awakening the Fairy Tail magic system. If you shake hands with someone for more than a minute, magic that is ten times more powerful than the other person will be drawn from the system! On the eve of the war, Ace disappeared. Zuowu shook hands with everyone in the Whitebeard Pirates one by one and said goodbye. He went to the Navy Headquarters to work as an undercover agent and became a Navy Admiral! Marco: "Dad, something is wrong. Zuowu has become an admiral of the navy. He doesn't really want to side with the navy." Akainu: "With the fourth general of the Navy, Zuo Wu, no one in the Whitebeard Pirates can leave Marineford alive!" Garp: "Be careful, Luffy, this new admiral is not our actor." Zuowu: "Fairy Law!" Kizaru: "What's going on! Zuowu is also one of ours?" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
