Lin Sui, a well-known essayist at the Agricultural University, opened his eyes and became a poor peasant who was about to starve to death on his way to escape famine in ancient times. It starts with a bowl of porridge that is clearly visible, two younger siblings who are so hungry that they are chewing tree bark, and a pair of gloomy parents. Desperate? No, the farming soul engraved in the DNA is burning! There is no space, no system, no spiritual spring, only a brain with advanced agricultural technology and a heart to maximize the yield. Others are still praying to gods for rain, but Lin Sui has already started building karez and water conservancy channels; others are still planting extensively and harvesting little, but Lin Sui has already engaged in breeding, grafting, and intercropping; while grass grows in other people's fields, hers grows legumes that can fix nitrogen and milkvetch that can be used as feed. Villager A: That girl from the Lin family is crazy. If she grows grass in the ground, can she still grow crops? Villager B: Her melons are bigger than the other and so sweet! I heard that it was sold in the county for a huge price! The young master from the landlord's family in the next village, a sick man who could not lift the rice with his hands or shoulders, would hang out by her field every day, waving his fan and saying, "Little girl, can the yield per mu really be doubled? If you do, I will give you a year's rent free!" Later, looking at the mountains of grain, the young master stopped shaking his fan and went out to help count the money in person. He smiled happier than anyone else. Later, Lin Sui's high-quality and high-yield grain seeds were "rolled" all the way from remote small counties into the capital. The emperor, who was distressed by the disaster: Hurry up for eight hundred miles! Please quickly invite the agricultural wizard Lin Aiqing to Beijing! My country... No, my granary depends on you! Lin Sui carried the hoe and looked at the people behind him who were waiting for food and the eager court officials.
