The late emperor passed away suddenly, and his posthumous edict ordered Shen Zhaoning to take over as regent! The government and the public are in an uproar, the clan wants to kill her, the powerful officials are setting up a trap, and even the people she trusts the most have hidden murderous intentions. King Su Pei Yuanhui held a military talisman in his hand and watched with cold eyes; the imperial physician Su Yunsi used medicine as a blade and worked step by step; the mysterious woman Jiang Yuheng sneaked into the palace, and her life experience became a mystery. She is not a queen, not a queen mother, but a candidate for the empress despised by the world. In this Forbidden City, where every step of the way is murderous, she will use a posthumous edict as a shield and the human heart as a sword to tear open the thousand-year-old web of patriarchy.
