Farming in the Southern Wilderness

In the third year of Liang Ping's reign, there was a severe drought. When Lin Yuanzhou woke up, his mouth was full of earthy smell. He remembered that he fell into a mudslide on the poverty alleviation road, and when he opened his eyes again, he saw cracked earth and dead trees with their bark gnawed away. Next to him lay an emaciated corpse, with a yellowed exile document in his arms - it read, "Lin Yuanzhou, a sinner, will never be employed." A mechanical voice suddenly sounded in his mind: "The Shennong system is activated. It is detected that the host is in a state of hunger. Edible plants within five kilometers around it: thatch roots, fern roots, purslane... Quantity: insufficient to support three days." Lin Yuanzhou was stunned for three seconds, and then smiled bitterly. In my previous life, I taught farmers how to plant scientifically, but in this life, I have to learn how to dig food from the soil first. What he didn't know was that this desolate land in the south would be completely changed because of him. And those high-ranking nobles will also be pulled down from the altar by a group of mud-legged men holding hoes in the near future.
