Su Li, the legitimate daughter of the duke's palace, was reborn. She saw through Emperor Kuang Xuanjin's plot to destroy the family at the provincial court, and angrily killed the emperor. During the crisis, she encountered Kuang Yinzhou, who had the same appearance as the emperor, and used poison to coerce him into pretending to be the emperor to stabilize the situation. Su Li, who is burdened with a blood feud, and Kuang Yinzhou, who hides the mystery of his life experience, grew up as false emperors and empresses who plotted against each other, working side by side in the intrigues of the palace, and gradually fell in love. The two team up to fight against the Queen Mother, solve the crisis in the palace and the court, and uncover the truth about the twins' life experience and the death of the late emperor. In the end, the barriers were broken, from a false alliance to a beloved comrade-in-arms, sharing the power of the country and the rule of the world.
