The concubine Shen Ciyou was forced by her biological father to replace her eldest sister and enter the seventh prince's mansion at the center of the whirlpool to become her "aunt". In the palace with strict hierarchy and intrigues, she worked step by step, taking advantage of the weaknesses of people's hearts to eradicate the vicious concubine and resolve the frame-up by her eldest sister. After discovering that the seventh prince Xiao Jingheng was in deep crisis, she was not willing to just be a vine dependent on the man. Instead, she turned into a counselor to contact the powerful officials and balance the forces. The two went from being suspicious of each other to fighting side by side. With the change of imperial power, Shen Ciyou followed Xiao Jingheng into the palace. In the bloody palace struggle, she defeated the authoritarian queen mother, purged her relatives, and finally ascended to the throne of the queen from the lowest level step by step, and took control of the country.
