The Splendid Medical Concubine: the Prince Regent's Favorite

A down-and-out noblewoman with peerless medical skills × a cold-faced regent who holds power in both the government and the public but is poisoned by a strange poison. It started with the transaction of "testing medicine" and "detoxification", and got caught up in the turbulence of the court and the rivers and lakes. In the end, they joined hands to clear up the government and the public, and established a prosperous medical relationship.
