Miao Yuan, the Holy Maiden of Miaojiang, seeks to break her curse of short life. She accidentally meets Emperor Zhou Jingheng, who has left the palace to seek treatment for a leg injury sustained in battle. She offers him a deal: "Bear my child, and your leg will be healed." They share a one-night stand, and she later gives birth to their son. In the chaos that follows, Miao Yuan administers the wrong medicine, leaving Zhou Jingheng infertile and unable to touch any other woman. Furious, Zhou Jingheng breaks off all ties with her. Six years later, Zhou Jingheng has sought countless doctors to no avail. Miao Yuan, as the Holy Maiden, enters the palace to treat him. As they spend time together, Zhou Jingheng gradually learns the truth of the misunderstanding from years ago. Meanwhile, Miao Yuan is moved by his patience and sense of responsibility. The two go from being wary of each other to falling in love. Miao Yuan uses her sacred secret arts to cure Zhou Jingheng's leg. In return, Zhou Jingheng proposes with his empire as betrothal gift and the mountains and rivers as oath, offering her the position of Empress. Together, they resolve court crises and finally become devoted spouses.
