Shen Qingci, a college student majoring in modern Chinese medicine, woke up dressed as a concubine of the Minister of Rites of the Yong Dynasty. She was originally weak and her biological mother was bullied, so she had to put away her edge and pretend to be "at her mercy". She secretly used her knowledge of traditional Chinese medicine to protect her biological mother and planned a way out of the Hou Mansion.
In an accident, she used medicinal food to relieve the old wounds of Lu Zhaoyan, the Marquis of Jingan. The cold and taciturn Marquis of Jingan, who held military power, started to explore her more. At the Queen Mother's birthday banquet, she attracted the favor of the fifth prince Xiao Jingyuan with a ballad, and her gentle pursuit made her heart beat. However, as the struggle for imperial power intensified, Xiao Jinyuan's "ambition" and "compromise" were gradually exposed, but Lu Zhaoyan always used actions to silently protect her. Even if she chose to escape from marriage, she persisted in pursuing it.
Beidi invaded and displaced people everywhere. Shen Qingci put aside his personal grudges and used medical skills to save lives and heal the wounded; Lu Zhaoyan led the army and fought bloody battles for the peace of his family and country. The two relied on each other in troubled times, and broke through in the intrigues, from the initial "suspicious trial" to the later "life and death together." In the end, the dust settled, Lu Zhaoyan gave up his power, and Shen Qingci let go of the past. The two took their biological mother away from the turmoil of the capital and found the happiness of "spring leisure in a brocade tent, staying together for a lifetime" in a small town in the south of the Yangtze River.
