Shen Zhiwei, the daughter of an imperial physician, disguised herself as a man to escape due to a family injustice, and practiced medicine with her senior brother Lin Jingyun to help the world.
Xiao Heng, the general's son, was seriously injured and rescued, and a secret love arose. After his identity was revealed, Xiao Heng proposed marriage but triggered the truth of the blood feud. Shen Zhiwei hated to escape and left with Lin Jingyun in a foreign country. Xiao Heng traveled all over the mountains and rivers to find her to reverse the case. When they met again, the plague was raging, Lin Jingyun turned black, and love and hate burned in the near-death decision.
The demise of the Shen family turned out to have another reason. Lin Jingyun deceived Shen Zhiwei, took her to a village in southern Xinjiang, and used love Gu to obtain Shen Zhiwei's body and mind.
Xiao Heng used his power to take back Shen Zhiwei, and the two fell in love and killed each other. In the end, the misunderstanding was resolved and they stayed together for a lifetime.
