The Top Demon King Actually Came to Learn Exorcism

My name is Xu Ye. When I was supposed to be studying at Jianhu Middle School, I was accidentally involved in an exorcism operation. When the old forensic doctor finally sent me an invitation to transfer to the Exorcism School, he was joking and hesitating for a second was all disrespect for the Jianhu school uniform I was wearing. That, of course, is to become a majestic exorcist. Who would have thought that the top exorcist who finally dominated the exorcism world would be a feared demon king.
