In the last years of Dajing, war smoke spread across the north and south. Beishuo's cavalry broke through the southern border of Yunzhou. Shen Yi, the commander-in-chief of Zhennan Army, died in battle. The Shen family was framed by treacherous ministers and was accused of "collaboration with the enemy and treason." His daughter Shen Qingci went from being a royal noblewoman to a wanted criminal overnight. In order to avenge her grievances, she concealed her name and sneaked into the Beishuo military camp under the pseudonym "Aci". However, she accidentally ran into Xiao Che, the "Snow Wind Yama" who was feared in the southern border.
