The Demon King's Palm Moon Pet

She was dressed as the most miserable sacrifice in the world of immortality. She thought she was going to be eaten by the Demon Emperor, but instead she became his exclusive moon pet in the palm of his hand. The crystal of demon power was used as snacks, and the demon power of his life was used as a spa. Zhengdao came to save him? Sorry, I have a better time in the demon world than the gods!
