The new emperor Yu Wenshang ascended the throne. In order to cover up the fact that she had tampered with the imperial edict - the fact that Prince Yu Wenyang of Jin was crowned emperor, the Ouyang Mansion, which knew the inside story, was exterminated. The entire Ouyang Mansion was raided. Only Ouyang Xueer, the young lady of Ouyang Mansion, survived. During the escape, Ouyang Xueer mistakenly believed that the person who caused the destruction of Ouyang Mansion was Murong Hengshen, an important minister of the court, so she decided to take revenge on the Murong family. At the same time, in order to stabilize the government, the Queen Mother named Murong Hengshen's daughter Murong Yu as queen at the state banquet. However, Murong Yu unexpectedly met her favorite Prince Jin Yu Wenyang at the state banquet. After entering the palace, Murong Yu gradually understood the palace's scheming and forced Ning Jin and the imperial concubine to death. Later, Ouyang Xueer's adoptive mother passed away. With the help of Shangguan Qi, Ouyang Xueer tried every means to enter the palace, and she was at odds with Murong Yu. In the harem battle, Ouyang Xueer gradually found out the truth about the destruction of the Ouyang Mansion. But at this time, the Queen Mother Qi Meng Minjia has arranged for her niece Qi Meng Jinnan to enter the palace, and the next killing in the palace begins again.
