Bai Nan traveled to the forbidden world of demons and obtained the strongest demon system.

After countless years of practice, he gradually surpassed other demon gods and became the strongest demon god. He has the power to control all laws at will, and can destroy the world at will and start from scratch. He has become the existence after all the magicians' wishes come true. Having become the ultimate being, he has no interest in conquering the world or anything like that. Wandering between worlds and other worlds in boredom. Until one day, the system suddenly issued a task, asking him to become a science teacher in Tokiwadai. And gave him a mission reward that he couldn't refuse. He laughed. It's really interesting that a demon at the pinnacle of magic actually teaches others superpowers. In his eyes, superpowers are just low-level magic...
