Shen Shuying lives a humble life in a border town, trying her best to hide her specialness. An incident involving the treatment of Beilin's wounded soldiers (possibly Xiao Che's subordinates) involved her in a border conflict, attracting the attention of Xiao Che and Xie Lin'an. Xiao Che approached her for investigating changes in the border (possibly related to Xuanming Pavilion) and the "medicine man" clues; Xie Linan came for protection. During the contact, Xiao Che was attracted by Shu Ying's tenacity and medical skills, and a secret love arose; Xie Lin'an's gentle protection also made her feel at ease. However, with the increasing pressure of Xuanming Pavilion, the emergence of clues about the treasures left by the previous dynasty, and a chance, Shen Shuying discovered that Xiao Che was the culprit of the Yaowang Valley massacre. Love turns to hate in an instant, and the flames of revenge are ignited. She used the power of Xie Lin'an and Nan Jing to deal with the two countries, struggling painfully between restoring the country (or seeking justice) and personal emotions. In the end, Xuanming Pavilion's world-destroying conspiracy forced everyone to put aside their personal grudges. In the process of jointly fighting against the ultimate threat, the truth was revealed layer by layer (including the complete truth of the Yao Ren experiment, Xiao Che's helplessness at that time, and the underlying reasons for the demise of the previous dynasty). Shen Shuying faced the most difficult choice: should she cling to the hatred of the past, or let go for the future of the people? In the blood and fire, can she and Xiao Che find the possibility of redeeming each other?
