When I woke up in the morning, I was startled to realize that I had gained insights from a hundred years later. I saw that floods in the south of the Yangtze River were still intercepted by ancient methods. I immediately issued an order: Set up a water level station according to the "hydrological monitoring" method, use "concrete" to solidify the embankment, and then send people to build a water pump based on the "water wheel principle".
Although the ministers were suspicious, they did not dare to disobey. After more than a month, the embankments were stabilized and the flooding gradually subsided. I caress the case and chuckles - the long-standing shortcomings of the Qing Dynasty will be slowly rewritten starting from these modern laws.
Very good book
