Pirate: Carry a Ten Thousand Souls Banner with You

Bei Gongwang, a modern man, accidentally traveled to the world of cultivation and chose to become an evil cultivator because of his qualifications. He never thought that after living for three hundred years and finally entering the Nascent Soul stage, he would be beaten to death by the righteous because of the growth of inner demons. When he was about to die, he once again traveled to the world of One Piece. As soon as he arrived, he found himself stranded on a deserted island. Fortunately, the natal magic weapon, the Human Emperor's Banner of Ten Thousand Souls, also came with him. By killing people, soul-binding training, and refining corpse puppets at the same time, an undead army with all Devil Fruit users was born without even realizing it!
