Age of Discovery: The Peerless Sword Immortal from the East Blue

After transmigrating to the world of One Piece, Su Mubai binds himself to the strongest lie-flat System and gets the Flying Sword Style and the famous sword Kikuchi Norimune from the start.

As long as he lies flat, he gets stronger. How could this get any better?

And so, as Su Mubai lazed around day after day, he discovered that he had no opponents left.

Sengoku: "If Su Mubai isn't eliminated, the World Government will be overthrown sooner or later."

Kizaru: "Have you ever been kicked at the speed of light? Wait, what do you mean you're faster than light?"

Whitebeard: "Looks like, with Su Mubai around, we really have become the remnants of the old era."

Akainu: "Su Mubai is the culprit threatening world security. He must be eliminated. Wait, big bro, can't you stop hitting my face?"

Zoro: "Damn it! Su Mubai sleeps on the ship all day, so why do I work so hard at training and still can't beat him? Is becoming the world's second-greatest swordsman really the peak of my career?"

Nami: "Actually, Mubai's greatest skill isn't swordsmanship. It's marksmanship."

Hancock, Robin, Vivi, Shirahoshi, and Momousagi: "Right, Nami's right."
