I'm Doing Dimensionality Reduction in Ming Dynasty

Li Mubai, who has a Ph. D. In mechanical engineering from Huaqing University, died suddenly after staying up late and traveled to Songjiang Mansion in the 28th year of Wanli. He became a young carpenter who was in debt and was about to starve to death. You start with a rusty chisel, a leaky shabby house, and a little sister waiting for food. Just when he was about to return to his old business, he found that the time he traveled through was not very good - the three great conquests of Wanli had just been completed, and the treasury was empty; the Jurchens in Liaodong were quietly growing; and in three days, the bullies were coming to collect debts. Li Mubai looked at the rusty chisel in his hand and made a decision that went against his ancestors - to build a hydraulic spinning machine and pay off the debt first. From then on, the painting style of the Ming Dynasty began to gradually deviate: The refugees who were supposed to starve to death entered his factory and became the first batch of paid industrial workers; the victims who were supposed to rebel received rations and went to night school to learn literacy; the Eight Banners cavalry that was supposed to sweep through the Central Plains encountered an armored chariot with a red cannon outside the customs. In the court, the Donglin Party called him a "monster who deceives the saints." The Eunuch Party wanted to recruit him into their gang. Even Emperor Wanli hid in the palace and secretly asked him: "Li Aiqing, that thing called a 'steam engine' can really make my dragon chair run on its own?" Li Mubai looked at this increasingly unfamiliar world and smiled slightly: "Your Majesty, where are you?"
