Nine-year-old Ye Fushuang personally experienced the Qingshangu massacre and miraculously survived. Fifteen years later, she has become a highly skilled doctor, refusing to treat the poisoned crown prince, thereby uncovering a long-dusty old case from many years ago. She brings her clan's remains to the capital, publicly exposing the truth that her biological mother Jiang Mingyuan bloodbathed Qingshangu and usurped someone else's identity to enter the palace. The wrongful case is vindicated, and Ye Fushuang returns to Qingshangu to set up a stele to state her ambition, saving the emergency and the poor, but not saving those who commit evil.
