Zhenguan Technology Empire

When Li Ming, a doctor of mechanical engineering, opened his eyes, he was transported to the first year of Zhenguan after the Weishui Alliance - plague was raging in the border town, aristocratic families monopolized resources, and Li Shimin was still relying on "Government of Virtue" to support the Tang Dynasty. With a knowledge base of modern technology, he started with a distiller to dispel the rumors of "outraging the gods": the improved Quyuan plow doubled the yield per mu in Guanzhong, built a modular crossbow machine to help Li Jing eliminate the Turks in advance, and set up a field hospital to halve the losses in the battle of Goguryeo... However, unexpectedly, Li's technology in Longxi failed, Zheng's leak in Xingyang was framed, and Confucian scholars expressed concern about "cesarean section" The ethical siege put him in desperate situations several times. Fortunately, Su Ning, the daughter of the Pei family in Hedong, who was both skilled in medicine and arithmetic, accompanied him in life and death: she used data to debunk counterfeit technology, used medical books to prove the legality of surgery, and accompanied him from the ruined temple to the Polytechnic College; his adopted son Li Ji and his grandson Li Ge took over the technological torch and guarded the bronze plate of the "Zhenguan Technical Code" in the undercurrent of changing dynasties. When Li Shimin shifted from "moral governance first" to "technical universal benefit", when the prototype of the steam engine was running in the mines of Datang, three generations of men worked for 23 years, rewriting not only the history of Zhenguan, but also the trajectory of China's technological civilization - but how many unfinished missions are hidden in the ultimate counterattack of the aristocratic family and the thousand-year protection of the underground palace?
