[Hardcore tech + infrastructure mania + no conquest of the realm + lighthearted power fantasy] A jaw-dropping start! Jiang Haotian, an agronomy master’s graduate from a top university, was struck by lightning and had his soul transmigrate into a Qin Dynasty prison at the end of the Qin era! From the start, he was sentenced to hard labor building the Great Wall. The land was full of starving corpses, and human lives were worth less than grass. Luckily, Heaven hadn’t taken away his **“ultimate golden finger”**: a mind packed with modern scientific knowledge!
While everyone else still relied on the weather, he improved the soil and increased yields from a hundred jin per mu to a thousand!
While everyone else still farmed with fire and stone tools, he built waterwheels, ensuring bumper harvests in both drought and flood!
While everyone else fought bloody battles, he used “food diplomacy,” making warlords from every faction come to him for grain and bow in submission!
From a refugee barely clinging to life, to a guest of honor courted by every power, and finally to the point where even Liu Bang had to bow his head and trade a whole state for an independent marquis who would neither take orders nor attend court!
Ask who he is, and the answer is simple: the ultimate “farmer king,” carried along by the tide of the times!
The angle is okay, there are no system cheats, it's close to reality, I added a bookshelf, I hope it won't break down after writing about it, come on⛽
