Re-Employment of Poor Agricultural Students in the Shennong System [Eastern Han Dynasty]

[Agricultural students who traveled through time were physically assaulted by a sycophant at a young age and farming infrastructure was relaxed and funny] Xia Chengchuan was about to graduate from his third year of graduate school in agriculture. He stayed up all night and failed many experiments, and finally passed out. When he opened his eyes again, an unexpected line of system prompt text appeared in front of him. [Hello host, welcome to Shennong System~] [The host is currently located in a village during the Eastern Han Dynasty. As long as you complete the tasks specified by the system and increase the average grain surplus of local farmers to ten stones within ten years, you can unlock the "Returning to Farming Dream" achievement! "What's the use of that?" [After achieving the achievement, the host can return to the original world~] - Since you want to plant the land and have a good harvest, you must start with tools. Now is the Eastern Han Dynasty, there are no barrel carts yet, and the curved shaft plow has not been invented yet, so there is really plenty of space left for him. Xia Chengchuan moved quickly and immediately began to observe the surrounding environment. Rice is grown all around, that is in the south. The water system seems to be quite developed. There is a river within a few steps. The fish in the river... No, that seems to be a person! - Xia Chengchuan picked up Bai He in this unclear way. Bai He claimed to be the owner of a herbal medicine shop. He had a good-looking face and a tall and powerful figure, but his eyes revealed a clear sense of stupidity. "Thank you for saving me. Can I... Can I live with you?" Xia Chengchuan, who was homeless and without a house or land, couldn't ask for anything more. - There are rumors in the village that the fool who runs the drug store has found a madman, and the two men are living together. What does it look like? Bai He actually just looks stupid, but he is quite strong and very obedient to orders. He can chop wood, forge iron, and saw wood. [Hello host, your current task progress is 40%, keep working hard! The next step is to improve the soil, raise seedlings, pesticides, fertilizers... Some things that I have memorized in my previous life. He was not stingy about teaching these things to others. After all, his mission was to increase the food production here, so even those who had laughed at him and Bai He before, Xia Chengchuan followed his instructions. [Hello host, your task progress is currently 30%, keep working hard! "What??? Why are you still going backwards?" [Hello host, the system requires farmers' surplus grain! - Bai He, who was returning with food, bumped into Xia Chengchuan, who was looking sad. "Achuan, I can help you." "What can you help me with? Don't you only know how to collect herbs?" "Actually, Ah Chuan, my biological parents don't live here. I was born outside the customs." Born outside the customs, his mother died early and his father's whereabouts are unknown. He lived in seclusion in the countryside in his youth, and was later recommended as an official by Uburg... When I go, he actually meets the famous Bai Qihua!
