Northern Song Dynasty: from Cottage Farming to Changing Times

Biologist Li Yiheng fell off a cliff and traveled deep into the Wumeng Mountains in the early Northern Song Dynasty. There is no golden finger, no system, only modern knowledge. When he opened his eyes, what he faced was: a leaky hut, a group of hungry mountain people, and the death line of being unable to pay the rent in a month and a half and turning the whole family into slaves. He built a rice grinding machine and harvested half a month's worth of rice in three days; he made steel using local methods and cut off the chieftain's servant's knife; he brought back salt and iron from the Forbidden Mountain, allowing the entire village to eat for the first time. In three months, he led a group of mountain people who had been oppressed for half their lives and overthrew the brutal chieftain. The eighteen villages bowed their heads and respected him as the "Messenger of the God of Plato". But on the night of the celebration, he found a notebook in a stone house that had been locked for a hundred years—— A hundred years ago, another time traveler came. The last page of the note reads: China's difficulty lies not in technology, but in system. If you want to break the situation, you must enter Bianjing. Li Yiheng closed his notes, changed his name to Li Zhiheng, and walked out of Wumeng Mountain. Next stop: Bianjing.
