Travel Through Ancient Times and Become Number One in the Country by Relying on Mathematics, Physics and Chemistry

After sleeping like an ancient county magistrate, I looked at the impoverished county thousands of miles away and smiled. Drill ditches, build water trucks, and use advanced mathematics to calculate optimal irrigation models. Build blast furnaces and refine steel, both physical and chemical. While the people in the county had enough to eat and clothing to wear, the surrounding counties and cities boycotted our dumping of goods. I calmly took out the last textbook: "Grassroots Social Organizations and Militia Training Manual." "Since the market economy doesn't make sense, let's compete on another track."
