Lin Wanqiu, a modern medical student, transmigrates to the Tang Dynasty after a car accident and awakens to memories of two lives as a concubine-born daughter. She is trapped by the constraints of her status in a feudal household, yet holds the means to break through them in the form of modern medical knowledge. Armed with techniques such as sterilization and managing difficult childbirths, she practices medicine under the guise of "family secret remedies" during the prosperous Kaiyuan era, when medicinal processing is primitive and women are restricted from practicing medicine. Along the way, she confronts the influence of shamanistic treatments and traditional beliefs about "the body, hair, and skin bestowed by one's parents."

It conveys the values of scientific reason and a healer's benevolence, while using the upheavals of the years before the An Lushan Rebellion to suggest how individuals can use knowledge and innovation to advance society amid the tides of history.
