Xie Qingyi, a graduate student in the Department of History, accidentally traveled to the second year of Tianfu (902) in the late Tang Dynasty when he was studying "New Book of Tang" and possessed a Yangzhou scholar whose family was ruined. At that time, Zhu Wen took the emperor to order the princes, and the world was in chaos, with warlords fighting. Xie Qingyi disguised herself as a man and struggled to survive in troubled times. She traveled west from Yangzhou to Chang'an, where she met the wandering warrior Murong Chu and Li Waner, the daughter of the Fengxiang Jiedushi family, and became involved in the power struggle between Zhu Wen and Fengxiang Li Maozhen. Relying on modern historical knowledge and a deep understanding of the situation in the late Tang Dynasty, she grew from a powerless scholar to the chief intelligence officer of Fengxiang Jiedushi Mansion. She worked step by step in the chess game of power, and finally found her own place and destination in the troubled times.
