[No cheats+time travel+mortal protagonist+historical facts+difficulty+mechanical+chemistry+business+...] Traveling through Chongzhen, you start with a broken inn. Engineer Hu Zheng lived naked in the late Ming Dynasty. He had no system and no plug-ins. He only had a head full of physical, chemical and mechanical knowledge and a set of portable measuring tools. As soon as he took office, he was scolded by evil officials and made things difficult for him. He was deprived of money and food, and hungry people everywhere. He was even tricked by his master into emptying out the inn. Relying on the pharaoh's snake to establish prestige, making soap and refining glycerin to earn a pot of gold, and making compost to increase food production to attract refugees. Recruiting qualified workers, building blast furnaces, mass-producing glass and cement, self-developed rifle guns, hydraulic forging hammers, and a complete set of coal chemicals. The Fan family of Shanxi merchants was jealous of the recipe and frantically counterfeited it to block the trade routes. Corrupt officials came one after another to demand bribes and raids. Kong Youde rebelled and massacred the countryside, and the Qing army entered the customs and plundered every year. Qin Hao built the fortified city of Dinghai, built an entire industrial chain to monopolize northern trade, and made friends with Sun Chengzong, Lu Xiangsheng, and Tang Ruowang to break the situation. The Ming Dynasty was on the verge of destruction, and they immigrated overseas in batches to protect the people's livelihood. He was stationed in an isolated city, with all the guns and chemical industry, and he was surrounded by the Eight Banners' cavalry!
