During the Yongping period of the Zhou Dynasty, Shen was convicted by Taiyuan Hospital for being involved in the palace secret medicine case. The men of the family were exiled to northern Xinjiang, and the women were made into slaves in the palace. In order to find out the truth, Shen Qinghuan, the daughter of the Shen family, pretended to be a maid in the palace. Relying on the medical skills inherited from her family, she managed step by step in the turbulent harem and resolved crisis after crisis.
When Qing Huan was serving in front of the emperor, he accidentally discovered that the prescription his father had proposed was actually related to military rations in Northern Xinjiang. As the investigation deepened, she revealed a shocking secret: she was actually the orphan of King Zhenbei, and Concubine Xian was her biological mother. In order to cover up the truth twenty years ago, the Queen Mother did not hesitate to collude with Nanzhao to create a plague in an attempt to subvert the great Zhou Dynasty.
With the help of Emperor Yu Wenzhao, Qing Huan gradually awakened the blood of the Medicine King and obtained the inheritance of the Medicine King Valley. She resolved the plague with her medical skills, quelled the rebellion with her wisdom, and finally uncovered the Queen Mother's conspiracy and restored peace to the world. However, behind the truth are deeper palace secrets and bloodline entanglements. Qing Huan had to make a choice between love and responsibility, revenge and forgiveness.
