A daughter of an imperial physician who was sent to the palace as a political outcast used her medical and poison skills to carve out a way out for herself in the cannibal harem. She does not want to become a queen, but to become the most irreplaceable "healer" in the entire dynasty - when everyone thinks she is weak, she is already diagnosing the weakness of people's hearts with her pulse, and rewriting the direction of the chess game with her decoction. This is a history written with silver needles, and the selection of every acupuncture point is a precise power blow.
