I'm a County Magistrate in Ancient Times, and I Transform a Poor County from the Start

Sure enough, he is a man from science and engineering. He buys lard, plant ash, firewood, and hires women. Calculated, a bar of soap costs more than 5 cents. He sells it for 5 cents a piece and gives away the most profitable glycerin for free. He just wants to help people get rid of poverty. The county has only 3,000 households. How many pigs can be killed in a day? Is there so much lard for you? Even if each of the 3,000,000 households buys soap, it will only cost 15,000 yuan, right? I calculate that one piece of soap lasts ten days per household, which is only 3 pieces of soap and 15 cents per month. Not every household can buy soap. Where do you get the money to support people's livelihood? Why not make glycerin into perfumes and skin care products and sell them to wealthy people to make money for infrastructure construction?

The ending is too bad. Such an ending is so heartbreaking.
