Seafaring: My Haki Levels Up Without Limit, Leaving the Four Emperors Stunned

Luo Xiu transmigrates to the world of One Piece and activates a System. Any technique he sees just once, he can learn on the spot!

On top of that, his skills can be upgraded without limit, and the experience required never changes.

Iron Body makes you either dead or injured if you hit it?

Upgrade it to Lv. 100. I’ll stand here and let you hack away. Think you can hurt me?

Observation Haki lets you foresee the future?

Upgrade it to Lv. 200. My foresight is better than yours!

The Red-Haired Emperor has the strongest Conqueror’s Haki?

Upgrade it to Lv. 500. Red-Hair, don’t talk to me on your knees. Look me in the eye, you bastard!

Mihawk: “I can’t cut him! I even chipped Yoru, and I really can’t cut him!”

Kaido: “One slash! That guy needed only one slash! I was almost cut in half!”

Red-Hair: “He only glared at me, and I fell to my knees. I really couldn’t get back up!”

At the Summit War, Luo Xiu single-handedly beat the Four Emperors to a pulp, trampled the Five Elders, and dragged Imu down from the Empty Throne.

With the whole world watching, he declared:

“Starting today, I shall stand above the heavens!”
