I'm Going to Help Luffy in the War

Fourteen-year-old Deng Xu traveled to the world of pirates and had a gentle personality. The bottom line was that he would never harm Luffy and his friends. He possesses resilience several times that of ordinary people, as well as a terrifying learning ability that can be learned at a glance. The bandit's fist can be mastered after one hit, the navy's six moves can be mastered after one look, and the swordsman's slash can be mastered by dodging it once. But he never actively hurts anyone, he just stands behind Luffy gently and beats down everyone who wants to harm the Straw Hats. My name is Deng Xu, and I am a gentle man. After saying that, he smashed the wall of the Navy headquarters with one punch. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
