Inner Demon

Li Yunxin is a human being, but he behaves like a demon. He was a psychologist in his previous life. Now, he has been reincarnated as a painter who knows how to cast spells, but he knows best how to manipulate the humans' minds. He's chased by Taoists, so he teams up with demons. Whether they are humans or demons, they will eventually become pawns of Li Yunxin. Even the two soul collectors would ask him, "Where are you from, cannibal demon?" Li Yunxin eats humans, as well as their hearts.
Brief introduction: Li Yunxin is both a human and a demon.
