People in the Magical World, Playing with the Industrial Revolution

Lan Fei, who was reincarnated into a different world of swords and magic, discovered that his cheap dad turned out to be a noble little lord! It's a pity that the territory that was sealed was a desolate and barren land. It was difficult for the people to feed themselves, let alone pay taxes to their father. How does this work? If your father lives a good life, then you can live a good life with him! Lan Fei directly demonstrated the knowledge of his previous life and built a curved shaft plow in public. With the basic income from Quyuanli, Lan Fei continued to purchase materials. Crazy infrastructure such as excavators and road rollers; combine harvesters and tractors liberated the labor force; various large-scale factories were built, and my father's fiefdom became an industrial city. When other lords had evil intentions towards this fiefdom, the dark muzzles of rows of Tiger tanks were aimed at his castle... Cheap Dad: King, let me sit in this position, right?
