One day, Chinese medicine doctoral student Shen Qingheng transmigrates into the body of Shen Qingheng, a daughter of a convicted official, branded a slave and awaiting transport in a prison cart, with only half a volume of the Shen Family's Essential Guide to Women's Medicine in her arms. With three fingers on the pulse, she detects the cold poison in Prince Jing Xiao Yan's blood. With a single dose of Spleen-Tonifying Decoction, she wins the respect of the noblewomen in the palace. From the Imperial Medical Bureau's dispensary to the Jikun Hall Women's Clinic, from slave status to an imperial appointment as Chief Female Physician, she wields silver needles like a sword and the scent of medicine as armor, carving out a way to survive in a world ruled by men and rigid social ranks. Xiao Yan asks her, "When you woke up in that well, did you ever imagine this day would come?" She smiles. "All I thought about was staying alive. But staying alive taught me there's something more important than survival."
She heals the world with her medicine, and he protects her for the rest of his life.
