Apollyon.

God created the universe and, after sleeping for 1,000,000 years, decides to reincarnate in a random plane of his universe to experience what life would be like for a normal person. He created a compassionate world, but when he was reborn, he realized that the world had become ruthless and unforgiving. Even though he has lost his cultivation, he will return to the top with his mortal body and restore order to his universe.
