Reborn as Jin Yuyan, the daughter of Li Chaoyong, she entered the palace with the memories of her previous life. Seeing through the harem Liangbo and Li Chao's scheme, she worked step by step, taking advantage of palace battles to clear obstacles, and used her resourcefulness to pave the way for her son Yongxun to become king. From a humble princess to a powerful imperial concubine, she won the throne, but spent her whole life in love, hatred and calculations, leaving only a legacy of "never forget the emperor's duty".
