Records of the Ming Dynasty's Entry into the Tang Dynasty

The soul travels through the late Sui Dynasty, and the beginning is a dead end. One moment ago, he was Li Cheng, the Minister of Industry of the Ming Dynasty. He had just finalized the layout of the firearms in Stagong, and then passed away in a sleepy state; The next moment, he became Acheng, an orphan boy in Luzhou, lying in a drafty adobe house, hungry and cold, and might starve to death at any time. Fortunately, he brought with him a wealth of military expertise. Improved agricultural tools, trebuchets, repeating crossbows, sky-shaking thunders, waterwheels and iron furnaces... These were not top-notch skills in the Ming Dynasty, but in the late Sui Dynasty, they were all magical weapons. Meeting Li Shimin by chance is both an opportunity and a crisis; Assisting Li Tang in raising troops was both a matter of trend and a game. He does not seek power to dominate the government, but only seeks to protect his knowledge and survive in troubled times. But the traces of the ivory waistband are exposed, the inertia of history is pressing harder, Pei Ji's olive branch hides murderous intent, and Li Shimin's eyes gradually become more inquisitive. When the military wisdom of the Ming Dynasty collided with the iron horse of the late Sui Dynasty, Let's see how an orphan boy, as a craftsman, became the driving force behind a prosperous generation!
