The Flat-Headed Demon Emperor of the Prehistoric Times

Above the nine heavens, a majestic figure sat in the temple. He held the Book of Ten Thousand Demons and declared majestically to the world. "Between all living beings in the heavens and in all realms, they do not belong to gods, immortals, demons, witches, ghosts, or humans. All those with spirits are demons. Those who are demons enter my demon status, accept my inheritance, enjoy my glory, and learn from the way of heaven."
