Yuan Jin: Imperial Master of Science and Engineering

In the eleventh year of Zhengzheng, he was born in Xin Mao. In the Central Plains, locusts are suffering from drought year after year, and people die of hunger everywhere. The iron hoofs of the Yuan Dynasty crushed the fabric of farming civilization, and the yoke of the four-class system made the Han people all over the world breathless. The wine ponds and meat forests of the Mongolian nobles were piled on the bones of tens of millions of refugees; the tyrannical expropriations of the lustful officials drained the last inch of the land of its vitality. Outside the city of Haozhou, famine followed like a shadow; beside the Yingzhou road, an undercurrent of resentment and resentment surged. This is the last year of the Yuan Dynasty. The Huanghuang territory has long been riddled with holes, and the illustrious imperial power is only brutal and lingering. Troubled times are coming, and human lives are like straw, but this is also the prelude to the emergence of heroes in large numbers and the reversal of the world.
