Zhao Changming, a top student in the Department of History, fell down the steps while rushing to write his thesis. When he opened his eyes, he turned into a poor Jurchen peasant in the Taihe period of Jin Zhangzong. The family is impoverished, the father is ill, the brother is thin, and there are nobles eager to seize the land - the beginning is hell difficulty.
He used modern agricultural technology to grow life-saving food and used historical knowledge to see through the trap of "enclosing fields". However, he witnessed Jurchen soldiers oppressing Han people in a market town, and only then did he understand the blood and tears of the "prosperity" of the Jin Dynasty. The war between the Song and Jin Dynasties, the rise of Mongolia, the depreciation of the currency, and the countdown to the collapse of the dynasty have begun. He no longer only seeks a way out: he improves infantry tactics to resist the Mongolian cavalry, proposes a "new policy of equalizing land" that touches the interests of the nobility, unites with monk Wan Yan and Chen, rescues exiled Confucian scholars, and steps from rural farmers to the central government.
But the inertia of history is like Mount Tai. Can he single-handedly hold back the Jin Dynasty heading towards the abyss?
