The Whitebeard Pirates' Cultivator: Slashing Marineford With One Sword

Ku Lun transmigrates to the world of One Piece and obtains the Cultivator System.

After giving the Tremor-Tremor Fruit to his sworn brother Whitebeard, he chooses to go into seclusion and cultivate.

Sixty years later, the Summit War is imminent.

With his pirate crew facing death, Whitebeard grits his teeth and travels to the Sea of Death to seek help from his sworn big brother, Ku Lun.

One pill makes Whitebeard young again?

One sword manual turns Vista into the world's greatest swordsman?

At the Summit War, a flying sword appears out of nowhere, rending the heavens and splitting Marineford apart.

Fire Fist Ace is rescued, and Akainu dies on the spot.

Whitebeard: "If anyone who's still breathing dares to defy me, let them take it up with my big brother!"

"Defy me? Before a cultivator like me, even the strongest are nothing but ants!" Ku Lun declares proudly.
