During the reign of Emperor Wu of the Han Dynasty, Liu Xijun and Liu Jieyou, the royal family members of the Han Dynasty, fell in love with each other like sisters in the palace, and accidentally met Huo Shen, the son of Huo Qubing. The Wusun envoy from the Western Regions went to Chang'an to seek marriage and alliance. Liu Xijun was canonized as a princess and went to Wusun to make a marriage alliance.
In order to imitate her father's meritorious service, Huo Shen was appointed by Emperor Wu of the Han Dynasty as a Han military captain and escorted Xijun to the Western Regions. Before leaving, Huo Shan asked her uncle Huo Guang to take care of her and relieve her worries. Huo Guang and Hejian King Liu Shou arranged for the maid Feng Liao to enter the palace and became friends with Jieyou.
Xijun married Wusun Wang Junxu for three years. After giving birth to his daughter, he fell ill and died of illness due to longing for his hometown. Jun Xumi felt that the Han army had a good relationship with Wusun and intended to continue to propose marriage to the Han Dynasty. In order to ensure the consolidation of the alliance between Wusun and the Han Dynasty, Huo Shen escorted the envoy Wu Zhini to Chang'an. On the way, he fought with the Huns army and was injured and separated.
Jieyou experienced the death of Xijun, and gained a new understanding of marrying Wusun and settling outside the Great Wall while in the palace. Jieyou performed a dance at the occasion when Emperor Wu of the Han Dynasty celebrated the birthday of the prince Liu Kun, and offered to replace Princess Xijun and go to Wusun to get married. Feng Liao was worried that she was acting impulsively. Jieyou did not notice Huo Shen's return in the ranks of General Li Guangli of the Second Division, so he made up his mind to leave Chang'an.
Huo Shen recovered from her injuries in the Cheshi tribe. At the border, she saw the marriage edict between Princess Jieyou and Wusun. Together with the Cheshi people, she drove away the Huns' nuisance and protected Jieyou to reach Wusun safely. Jieyou tried his best to help the people of Wusun live and work in peace and contentment, and even helped Jun Xumi open the passage, allowing Wusun and Yuezhi to go to the Han Dynasty as envoys to promote exchanges between the Han Dynasty and various ministries in the Western Regions...
