Great Voyage: the Invincible Swordsman of the Garp Family!

After traveling through the pirate world, he became Garp's nephew and Luffy's uncle. He thought that his position as a general was stable, but he discovered that God seemed to have made a joke. His physique is not even as good as that of a new recruit battalion. Fortunately, he has awakened the strongest Zanpakutō system and can give his sword the ability of any Zanpakutō. Akainu: "Roger's blade was like fire and almost burned me to death!" Hawkeye: "Roger's Lightning Pill Slash can catch my slash with his eyes closed. I am ashamed to be named the world's greatest swordsman!" Kaido: "Rogg is so scary. He kills me with his sword, and all my men come to kill me!" The introduction is weak, please read the text ...
