Rong Qingyue, the daughter of an imperial physician, swore not to marry due to her mother's hemorrhage due to dystocia, and lived in seclusion in Yao Valley. She rescued the Northern Territory Protector who was assassinated, but found that the medical document on his body was written in the same handwriting as the medical record of her mother's death. In order to find out the truth, she disguised herself as a man and followed him back to Beijing, uncovering the scandal that her biological father had killed his wife with fake medicine. It was revealed to the court that he was about to die after being beaten with a rod, and he handed over a blood-stained marriage certificate: "If you think it's unlucky, I will burn it for you to be buried with me." She burned Shili Hongzhuang in public, but kept the blood book: "This agreement is only to cultivate the medical code together." On the day she was awarded the "Medical Couple" gold plaque, she was bandaging his new wounds after returning from guarding the border.
