The story of a young man who traveled back in time to the Song Huizong era and helped the emperor unify China. The dusk in Bianjing City is like blood, and there are a few unextinguished river lanterns floating on the moat. Cheng Mo suddenly woke up in the biting river water, choked and coughed, and grabbed the weeping willow on the bank. His last memory still remains in the Songcheng Scenic Area in Hangzhou in 2023 - as a graduate student in the history department, he was photographing materials for his graduation thesis "Examination of the Military System of the Northern Song Dynasty", but was engulfed by a golden light while touching the imitation Xuanhe Tongbao bronze mirror.
