Su Che is exiled to Qinghe Town in the northern lands. Right from the start, the town chief steals his cotton-padded coat and throws him into a desperate snowstorm where temperatures plunge to minus twenty degrees. Facing an impossible situation in which 300 displaced people are about to freeze or starve to death while being exploited by corrupt officials, Su Che uses his modern knowledge of chemical engineering, agriculture, and industry to gradually transform Qinghe Town into an early industrial city built around coal, farming techniques, greenhouses, and steel. As his work, The Su Family's Agricultural and Industrial Handbook, spreads throughout the land, even the imperial court can no longer sit still.
