Youyou, a college student majoring in veterinary medicine, broke up with her boyfriend because she was disgraced by her profession. Out of grief and anger, she stumbled and fell into the Tiger Park. She was transformed into Liu Jieyou, a criminal slave in the Western Han Dynasty. Her father died, her mother died, and her younger brother An An was also kidnapped for purification. In a desperate situation, in order to save An'an, her cousin Xijun, who was also a sin slave, took the initiative to marry Wusun on behalf of the princess, and begged the princess Hao Fu to relieve your worries and An'an to leave the palace. Xijun deceived Jieyou into agreeing to get married just to pursue freedom, but he died of an illness three years later due to acclimatization. In order to protect his younger brother, Jieyou accepted the marriage decree, said goodbye to his first love in Chang'an, and embarked on the yellow sand road to Wusun. On the way, she used her modern knowledge of animal husbandry to treat sick horses and find hope in sandstorms, which impressed the indifferent Prince Wu Sun, Weng Gui Mi. Arriving at the royal court, she became a political pawn, marrying Xumi, a Kunmi army who was swinging between Han and Huns, and had to deal with the beautiful Zuo Madam sent by the Huns. The pro-Hungarian ministers regarded her as a thorn in their side and made things difficult for her at every turn. Attila, the left wife, died in childbirth, and the military officer Mi was heartbroken and seriously ill. The Huns took the opportunity to attack the city, and rumors pushed Jieyou and Weng Guimi to a desperate situation. Before his death, Mi Tuogu, the military commander, ordered Weng Guimi to marry her according to Wusun customs... When the spring breeze blows across the grasslands of the Western Regions, can she become a legend that illuminates the peace between Han and Wu?
