PLOT
Yun Lei's grandfather Yun Jing was detained by Zhang Zongzhou for many years during his mission to the Wa State on behalf of the Ming Dynasty, and later died as a result of being punished by Emperor Yingzong of Ming. Yun Lei swears to avenge him. Disguised as a man, Yun Lei goes to Beijing to find her long-lost brother Yun Zhong, and meets Zhang Danfeng and Shi Cuifeng, which leads to a series of complications. Eventually, Zhang Danfeng decides to abandon his personal grudges and prioritizes sending a map of military affairs to the official Yu Qian, while resolving to resolve the feud between the Zhang and Yun families in his own way.
