It tells the story of Feng Qingyin, a modern female doctor who accidentally awakens the power of the Phoenix and travels to the Longyuan Dynasty to get married. She was forced to get involved in the robbery of the regent Long Ming - he, with the blood of the evil dragon, regarded her as a secret medicine to suppress the loss of control. Feng Qingyin camped step by step in the deep palace, waiting for an opportunity to escape, but she didn't know that the two were actually the dragon god and the phoenix goddess who were forced to separate in ancient times.
Misunderstandings and conspiracies finally led her to escape from nirvana, and her past life memories awakened when she was about to die. Long Ming lost his beloved, and changes occurred frequently in the world. A year later, in order to heal the disaster and unresolved love, Feng Qingyin returned as a goddess and fought against the ancient beasts side by side with Long Ming, who was on the verge of collapse.
After experiencing the disaster, Long Ming put aside his paranoia, and Feng Qingyin also understood his affection. After thousands of years of knotting, the dragon and phoenix work together to determine the world. They agree to join hands in the ruins and the mirror circle is reborn.
