During the Jingyuan Dynasty, the imperial power declined, and various forces within the court were undercurrent. The prince Xiao Chengyu was at every step in the harem, and had to participate in the fight for the throne in order to protect himself. He met Jiang Wanyi, a daughter of an aristocratic family. The two supported each other in the power struggle and gradually developed feelings. However, the road to power was full of betrayal and sacrifice. Xiao Chengyu finally ascended the throne as emperor, but also lost many precious things. Jiang Wanyi gradually lost herself in the harem, and finally chose to protect the beliefs in her heart. The story shows the cruelty of the struggle for imperial power and the complexity of human nature, as well as the insignificance and powerlessness of personal destiny in the face of power.
