In her predecessor, she was Su Wan, the legitimate daughter of the Prime Minister's Palace. She was tortured to death by her stepmother Liu with the rotten heart poison. Her dowry was swallowed up and her reputation was ruined. Even her mother Wang's grievances could not be vindicated. When the modern Su Wan returned in spirit, she clutched the herbal atlas and half a jade pendant with a phoenix pattern left by her mother, and there was no trace of cowardice in her eyes. This is a legend of a legitimate daughter's counterattack, and it is also a love song between the god of war and the medical girl - overcoming the situation with wisdom, guarding each other with love, and protecting the world with benevolence. It has finally become a good story that will last for a hundred years during the Dajing period.
