The daughter of an imperial physician avenges her father and marries into a general's palace. However, she discovers that her husband is pretending to be ill and has a secret treasure from the previous dynasty hidden in the palace. The two go from suspicion to joining forces to break the situation.
In one sentence: an avenger and a pretender test each other in a general's palace with secrets, and eventually become each other's only knife.
Causal relationship: Starting setting - the heroine's father was executed for being involved in an old case in the General's Mansion, and she forged her identity to become the wedding bride. Foreshadowing - after the heroine enters the house, she discovers that her husband is pretending to be ill, and the prescription left by his father before his death is hidden in the map of the general's palace; the husband who pretends to be ill holds the last secret letter from the heroine's father in his hand. These two clues point to the same case of a treasure left by the previous dynasty, which was also the source of the unjust case that year.
Protagonist's Goal-Obstacle-Solution Path: Goal: Clear his father's grievances and find the real culprit. Obstacles: Everyone in the general's mansion has their own secrets, it is difficult to tell the authenticity of the husband, and clues to the treasure involve the influence of the court. Solution: Use medical skills to obtain intelligence about the mansion, pretend to cooperate with your husband but actually use each other, and finally reveal the truth when the treasure is opened.
