The demon-catching warlock Zhao Yujing was ordered by his master to travel down the mountain and came to Chang'an City. He found that the Emperor's Star was getting dark and there were many demons in Chang'an City. In the process of catching monsters, Zhao Yujing met Li Ju, the Eighth Prince who had been demoted to a commoner, and the two fell in love with each other as they got along. However, Concubine Wu Hui, who regarded Li Ju as an obstacle to her son's succession, could not keep him alive for a long time, so she designed a relationship between Li Ju and the emperor's favorite Princess Shou in order to completely eradicate Li Ju. On the other hand, in the process of hunting down the nine-tailed fox demon, Zhao Yujing discovered that the demon was very special and had an inseparable relationship with the palace struggle... In this fantasy love-hate entanglement, there was a battle of power and skills, a battle between men and monsters, and a simple but luxurious white-headed agreement.
