In the second year of Yong'an, the imperial censor Zhongcheng Shen Jing was framed and executed for impeaching Taiwei Xie Lin for collaborating with the enemy and treason. Only the young daughter Shen Zhewei was secretly preserved by the puppet new emperor Xiao Chiqian and was sent to Yeting incognito. After seven years of forbearance, Shen Zhewei broke the boat at the Queen's Qianqiu Banquet and reached a deal with the emperor with evidence of guilt. She rose from a lowly palace maid to a talented person in the imperial court, and stirred up the palace and the harem step by step. She and Xiao Chiqian, who seemed docile but had been dormant for many years, went from testing each other to becoming dependent on each other for life and death. They joined forces to eradicate the influence of the Xie family's relatives and avenge the 373 souls of the Shen family. In the end, Shen Zhewei ascended to the throne, Xiao Chiqian held on to the imperial power, and the two created a prosperous age of Yong'an, composing a sadomasochistic, affectionate and Machiavellian legend in which the emperor and the empress ran in both directions to protect the country together.
