Lin Mohun, a modern investment bank analyst, traveled back in time to the first year of Jingkang (1126) and became the lowest slave in the stable of Wanyan Zonghan, the marshal of Zhongdu of the Jin Army. He originally thought he was a dead end, but found that the Kingdom of Jin was facing a serious economic crisis - the army was in arrears, the nobles were corrupt, and internal strife was fierce. Lin Mo used modern financial means to help Jin Jun "realize logistics" and climbed all the way up to Wanyan Zonghan's closest aide. He had only one real goal: to hollow out the Jin Kingdom's war capabilities and build an armed force beyond the times for the Song Dynasty to move south before the city of Bianliang was destroyed.
