Economics Ph.D. Shen Mo fell asleep while working overtime, accidentally crossing over to the Daliang Dynasty to become the magistrate demoted to a barren county. In a disaster year with severed food supplies, commoners gnawed on tree bark, granaries were empty, and disaster relief grain was embezzled by powerful ministers. The former magistrate fled for his life, but he insisted on staying! Planting potatoes, breeding sweet potatoes, making soap, repairing grand avenues, opening iron mines, leading commoners to survive desperate straits with modern knowledge, and turning a poor county around in half a year. The emperor made an unannounced visit and saw granaries piled high, iron furnaces blazing, and roads accessible, while his counterattack had only just begun.
