The Science and Engineering Man's Guide to the Tang Dynasty

In the great Chinese year, the afterglow of the prosperous age has faded. The vassal town separated the mountains and rivers, and the eunuchs took charge of the palace, and there were many dangers. A splendid civilization is irreversibly sliding into the abyss. Li Yan, a distant branch of the royal family who was exiled to Penglai, and the county magistrate Zhimaguan. No one knew that in the mind of this frustrated magistrate, there was a fire of civilization from the future burning. While others were still struggling with their work, he had improved farm tools and made rice surge in barren land; When the court was still divided by party disputes, he built a blast furnace and let the torrent of steel replace cold-forged weapons; When the Forbidden Army was still indulging in pleasure, he developed the "Fire Dragon Arrow" and the "National Cannon" to form a silent and deadly new army. From salting and coking to shuttles and steamships; From Penglai County, to the land of Qilu, and then to Chang'an. The nobles said that he was a "female chicken Si Chen, with extraordinary skills and cunning skills". The eunuch scolded him for "supporting his troops with self-respect and plotting evil intentions". The feudal lord was afraid of him because he had "sharp weapons, like a demon and a god." What he wants to do is far more than just changing dynasties. He wanted to give this sluggish empire a backbone of steel, ignite the industrial fire, and let the light of reason dispel ignorance. Replace the lament of camel bells with the roar of steam engines; Use the new knowledge of geophysics to reshape the order of the world. This is a road no one has ever traveled before. The giants of the old era joined forces to strangle, and they were enemies on all sides. But Li Yan held the civilization map in his hand tightly and looked firmly: "Since the old body of the prosperous Tang Dynasty has decayed, then I will forge a new, immortal steel soul for it."
