Su Qin was abandoned in the wilderness due to family strife when she was young. She was rescued by a medicine farmer and his wife. After ten years of hard study, he finally became an expert pharmacist. When she was seventeen years old, news came back that her biological mother's old illness had recurred, and she returned to the Su Mansion with a medicine bag. Faced with mistreatment by her mistress, betrayal by her sisters, and contempt from her tribe, she used her resurrected medical skills to overcome the situation - curing her eldest sister's strange disease to establish her authority, relieving the old lady's illness and taking power, and poisoning her food to protect herself. In the process, she gradually uncovered the truth behind her mother's expulsion: it was actually a scheme devised by her grandfather in conjunction with an outside party to protect family secrets. When the Su family was involved in the court turmoil, she used her medical skills as an edge and took advantage of the house fights to protect her clan members and rectify her mother's name. She eventually became the real head of the Su family and found a new direction in life in medical classics.
