Reborn as the Strongest Swordsman of the Great Age of Sail

After transmigrating into the world of One Piece as Zoro, he joins the Marines and activates the Strongest Swordsman System: every swing of his blade adds 1 to its force.

And so Zoro rises to prominence on the seas, utterly unrivaled.

Sengoku: “Hey, hey, Vice Admiral Zoro, stop beating up Akainu! He's already unconscious!”

Garp: “Zoro! Why did you betray the Marines and join my grandson's pirate crew? What do you get out of it?”

Crocodile: “Somebody help me! How can a Marine vice admiral join the pirates? Who can handle this?!”

Mihawk: “Are you the invincible swordsman of the Marines? But why did you join this tiny Straw Hat Pirates crew?”

Luffy: “Hey, Zoro! Kaido's really strong. Come deal with him!”

The invincible Zoro declares that he can let Luffy become the Pirate King, but Nami, Robin, and the Pirate Empress are all his.
