The deposed queen Shen Zhaoning woke up in the cold palace with nothing but three uncorroded corpses in her hands. She neither cried nor made trouble, and only used acupuncture and anatomy to uncover a series of palace poison cases, dragging the powerful officials into death one by one. Xie Huaizhang, the prince of the prison country, watched with cold eyes, but he didn't know that she had already written his secret into the prescription. Cui Lingyi, the daughter of the Ministry of Etiquette, handed over the poison, the imperial doctor Zhou Yanqiu offered the antidote, the border general Pei Yan kept vigil silently, and the crazy former princess Su Yuyao carved words day and night - she was not seeking revenge, she was rewriting the rules of the entire dynasty.
