Leng Yan is an otaku. He originally thought he would stay at home for the rest of his life. Unexpectedly, he actually traveled through time and became a slave in One Piece. At least he has the fate of the protagonist. He ate the special natural Mumu fruit and overthrew the Shichibukai and became the new Shichibukai. Kaido was dishonest and overthrew Kaido and became the new Yonko. Jean Luo performed a special surgery on him, got a second heart, ate the Transfer Fruit, and became a person with dual abilities. He converted himself and the Devil Fruit's original tree, and Leng Yan became the Devil Fruit Tree. When he ruled 99 One Piece worlds, he thought he was going to live an invincible life, but he was pulled into the Marvel world by Marvel's God of Death, and people from other worlds were also pulled in. And so began another journey to become the Demon King of Marvel. Swordsmen, magicians, and warriors all became his demon apostles. Peter Parker ate the phantom beast species the Man-Faced Demon Spider and became the devil's apostle. Kingpin ate the ancient species Titan Fruit and became Leng Yan's thug...
