Sheng Minglan died in Guhou Mansion, but when she opened her eyes, she became An Yao, who had just been selected during the Yongzheng period. Faced with looks of disdain or pity from around her, she quickly calmed down from the shock. In her previous life, her transformation from a concubine to the mistress of the Hou Mansion had never depended on luck, but on the wisdom of perceiving people's hearts, the calmness to assess the situation, and the determination to never be merciful. In this life, living in a turbulent harem, she will use this "Sheng's philosophy of survival" to reverse the original owner's miserable ending of committing suicide as a slave in her previous life.
