At the end of ancient times, the Cang Emperor divided into three realms, the fairy world, the demon world, and the human world. Since the human world was very weak, most people went to the fairy world and the demon world to study. The immortal and demon worlds were the two most powerful realms in the world. The Cang Emperor held a war every five years. The story begins when Tao Ningning, the third wife of the Tao family, goes to the Immortal School to study and meets the demon king Tailing.
Intention: Meeting and parting are just an unsolvable gift to each other's destiny.
