Navigation: Incredible Understanding, the World's Greatest Swordsman

Traveling through the world of One Piece, Ron becomes a student of the Frost Moon Sword Hall! Poor qualifications and poor foundation? With the deduction space in mind, the direct understanding goes against the will of heaven. Who is the vanguard at the end of the sword's path? When it meets Ron, the path becomes empty. A famous sword of this era! Whitebeard: "You are the strongest man in the world!" Hawkeye: "The greatest swordsman in the world? I have already been surpassed by that man!" Auntie: "Well, Ron's swordsmanship suppresses the world!" Kaido: "Impossible, my immortal body has no effect under Ron's sword technique?" This novel and its characters are purely fictitious.
