Wearing the Mirror Style, I Become the Best Swordsman in the Pirate World

[One Piece + Mirror Style + Transformation + Time Travel + Honken Iron + Honkai Star Dome Railway + Invincible Style + Relaxed and Funny + Straw Hats + Daily Complaints] Traveling through the world of One Piece in one sleep, and accurately smashing into the Merry ship from an altitude of several thousand meters. I thought this was outrageous enough. Until he looked down - White hair, red eyes, long legs, and two huge obstacles that never existed before. Bad news: Niuniu is gone. Good news: It has become a mirror flow. Better news: Kagami's strength, swordsmanship, and fighting instincts all seemed to be inherited together. Therefore, the Straw Hat Pirates, who had just set sail not long ago, welcomed a new member with a seriously over-the-top painting style. Zoro: "Are you also a swordsman? Come to a duel!" Jingliu: "Okay." After a sword. Zoro: "... Why is the gap so big?" Jingliu: "You just need to practice more." Luffy: "Kageryu! Can your ice freeze meat?" Nami: "Can you stop asking her for everything?" Usopp: "Wait, she's not afraid of sea water?!" From the East China Sea to the Grand Line, from the Shichibukai to the Four Emperors, from the Admiral to the World Government. When the whole world is still arguing about the so-called "monsters" and "strong men"—— Sister Jingliu picked up Luffy and went up to chop him.
