Main plot: Su Qingtang was originally the most inconspicuous embroiderer in the embroidery workshop. She accidentally awakened the "Medical God System" because she performed acupuncture to save a dying old woman. The system used embroidery as a guide to activate her hidden medical talent. Relying on the ancient prescriptions and acupoint maps prompted by the system, she gradually displayed amazing medical skills, from treating homeless people on the streets to solving hidden diseases in the palace. Her rise angered Lin Ruoxue (a jealous villain), the daughter of the head of the embroidery shop who had bullied her, and the other party teamed up with noble ladies from the aristocratic family to set up a trap. At the same time, Gu Mingyuan (the sunshine hero), the son of the richest man in the capital, was attracted by her coldness and kindness as a doctor. He supported her along the way, but misunderstandings often occurred due to family marriage contracts. The two redeemed each other through medical competitions, palace epidemics, and poisoning plots. In the end, Su Qingtang proved his medical skills and revealed his life experience as the first orphan in the Tai Hospital. He joined hands with Gu Mingyuan to break the situation, and achieved a happy story of a sadomasochistic relationship.
