Chen Yan, a graduate student in the Department of Modern History, accidentally traveled to the seventh year of Xuanhe in the Northern Song Dynasty with a Ru kiln azure-glazed string-pattern vase in the Forbidden City collection - a turbulent era that was only one year away from the "Shame of Jingkang". Possessed by the Huzhou scholar "Chen Mo", he was involved in the escort robbery incident when he first woke up at the Suzhou dock. He was rescued by Shen Mo, the accountant of the Weiyuan Escort Bureau who had hidden martial arts. From then on, he stepped into the intertwined whirlpool of rivers, lakes and courts in the Song Dynasty.
