AD 1120, the second year of Xuanhe in the Northern Song Dynasty. Su Muye, an instructor at the Modern Military Academy, fell into a coma during a drill accident. When he opened his eyes again, he found that he had become a 25-year-old down-and-out scholar in Bianliang City, Tokyo. He failed three attempts, was in debt, and was extremely poor. On the first day of time travel, two debt collectors blocked the door. But these are not the most terrible things - the most terrible thing is that he clearly knows that six years later, the Jin soldiers went south, Bianjing fell, the two emperors of Huiqin were captured and went north, and the harem clan became slaves, which is known in history as the "Shame of Jingkang". The civil and military officials of the Manchu Dynasty were still celebrating the "Sea Alliance" that united the Jin Dynasty to destroy the Liao Dynasty. No one realized that it was a dead move. Su Muye knew all this, but he was just a poor scholar with no money, no power, and no connections. He must start from scratch, in this dynasty that values culture over military force, using modern people's brains and ancient people's rules, step by step rewrite the history that has shamed the entire nation for thousands of years.
