Gu Yan, a graduate student in modern history, specializing in Song history, was a madman studying Li Qingzhao. He stayed up late to revise his thesis and died suddenly. His soul fell into the body of a poor scholar "Gu Yan" in Bianjing in the third year of Yuanfu in the Northern Song Dynasty (1100). He foresaw the disaster of Jingkang, protected Li Qingzhao, and rewrote the national destiny of the Song Dynasty.
