Lin Yan, a doctor of science and engineering, was transformed into the sick son-in-law of an ancient peasant family. He started with thirty taels of debt, his father-in-law looked coldly on him, and the original owner coughed up blood and waited to die. In order to survive and pay off his debts, he took out the manual of "Homemade Steelmaking + Irrigation + Simple Chemical Engineering" and turned the deserted village into a granary in three years. He originally wanted to make money by farming, but he was admitted to the official school because of his merits in flood control. While others memorized the Four Books and Five Classics, he memorized "Tiangong Kaiwu" and "Elements of Geometry", used mathematical modeling to solve arithmetic, and answered questions on water conservancy projects, surprising the marking officials all the way. Originally he just wanted to become a scholar and continue to work on infrastructure, but because of his outstanding political achievements, he was targeted by the emperor and was forced to get involved in the court. Since you can't escape, then use infrastructure thinking to govern the country! Building post roads, opening sea trade, establishing schools... From being a farmer's son-in-law to becoming the most powerful person in the government, Lin Yan just wanted to say: I really didn't want to be the chief minister, it was this prosperous dynasty that forced me to get involved!
