Shen Tingmian, a modern university student, unexpectedly travels through time. When she opens her eyes, she finds herself on the battlefield at the border of the Great Cang Kingdom. With her identity unknown and unable to communicate, she is mistaken for a spy and brought before Lou Zhaohe, the Prince of Zhenbei. After confirming her innocence, this stern and imposing prince of a different surname allows her to stay in the military camp. In these chaotic times, life is difficult for a vulnerable young woman, but Shen Tingmian remains clear-headed. She has no desire for wealth or glory and refuses to depend on anyone. All she wants is to survive through her own abilities and find a way home. Faced with Lou Zhaohe's forceful probing, she neither lowers herself nor backs down, standing her ground with reason. Instead, she manages to impress a prince who has grown accustomed to flattery.
