At the end of the Xia Dynasty, the people of the world were in dire straits under the rule of the tyrant Jie. Yue Li, the daughter of a witch with a special bloodline and a hidden secret, was forcibly recruited into the palace because of her extraordinary beauty.

At the same time, a demon power originating from ancient times is awakening, and it is closely connected with Yue Li's destiny - she is the key container of the reincarnation power of the ancient demon king, and the seemingly loyal but unfathomable national master Xuan Ming beside Jie is the reincarnation of the little demon who defected from the demon king's throne. Xuan Ming planned for thousands of years, intending to use Jie's violence and Yue Li's specialness to awaken and seize the power of the Demon King, subvert the world, and rebuild the Demon Realm.
