A young man transmigrates to the Song Dynasty during the reign of Emperor Huizong and helps the emperor unite Huaxia.

Cheng Mo suddenly wakes in the biting river water, coughing as he grabs hold of a willow branch hanging from the bank. His last memory is of the Songcheng scenic area in Hangzhou in 2023. A history graduate student, he was collecting material for his thesis, “A Study of the Northern Song Military System,” when a flash of golden light swallowed him as he touched a replica Xuanhe Tongbao bronze mirror.
