Lin Mo, a modern investment banking analyst, transmigrates into the first year of the Jingkang era (1126) and becomes the lowest-ranking slave in the stables of Wanyan Zonghan, commander-in-chief of the Jin army stationed in Zhongdu. He expects certain death, but discovers that the Jin dynasty is facing a severe financial crisis: the army is owed back pay, the nobles are corrupt, and infighting is rampant. Using modern financial methods to “turn military logistics into cash,” Lin Mo rises through the ranks to become Wanyan Zonghan's trusted adviser. He has just one real goal: to drain the Jin dynasty of its ability to wage war and build an army ahead of its time for the Song court's southward retreat, before Bianliang falls.
