I don't know when I was born, and I don't know who my father is. I am reincarnated every 100 years, but Po Meng has never given me any decoction, and I can't remember where my abilities come from. Oh, by the way, my name is Xiyu, what is the purpose of my existence? I don't know, so what's the use of all my skills? I only know that it is my responsibility to eliminate evil spirits. Also, there is a person who has always been with me. I can't say he is a human being, and I don't know what he is? Immortal? It seems not, demon? That's not right either; demon? Not really; forget it, don't worry about it. Why don't I tell you about the fun and exciting things I have encountered over the past thousands of years?
