Forty Years of the Tang Dynasty

A bizarre laboratory accident threw Li Yunmi, a modern science and engineering man, into the suburbs of Chang'an in the early years of Zhenguan. Penniless, without any relatives, only a head full of modern knowledge and an empty backpack. At the beginning, he almost froze to death in the snow, but luckily he was taken in by a kind-hearted farmer. In order to survive and find a foothold in this glorious and prosperous age, he had to carefully use some "little tricks": a bowl of fresh chicken essence, a pot of hot pot to warm up, a simple epidemic prevention manual... But he was accidentally involved in the undercurrent of Chang'an City. I wanted to keep a low profile and farm, become a rich man, and live a stable life. However, the "wonderful skills" he brought were too dazzling: the "immortal prescription" (alcohol disinfection) that can make wounds less likely to fester, the curved shaft plow drawings that can greatly improve the efficiency of farming, the saltpeter method that can relieve the heat and make ice... These things are like pebbles thrown into the lake, and the ripples continue to expand.
