Xu Zhixia, a master's student at the Agricultural University, stepped into the air and transformed into an ancient refugee fleeing famine. It started with a bowl of clear soup, three hungry siblings, and a mother who was so sick that she was about to meet the King of Hell. Xu Zhixia: "..." Thank you for the invitation. You will be considered a success if you are alive. In order to survive, she decided to pick up her old profession - farming. When others were clearing land, she first tested the pH of the soil; when others were sowing seeds, she studied breeding and spacing; when others were watering, she designed a simple drip irrigation system; when others prayed to gods and Buddhas for a good harvest, she led the whole village to fertilize, eliminate insects, and engage in crop rotation. Villager A: "Zhixia, if you plant beans and corn together, God will be unhappy!" Later, looking at the beans crawling on the corn stalks, Villager A silently planted the same on his own land. Villager B: "Girls play with mud all day long, what does it look like!" Later, looking at the Xu family's newly built large brick house with tiles, Villager B knocked on the door with a hoe, "Well, Zhixia, do you think my land can be saved?" Xu Zhixia originally wanted to be a wealthy local man and live a leisurely life of "a peasant woman, a mountain spring, and some farmland." But the high-yield grain she grew met the military needs; the cold-resistant cotton she cultivated warmed the borders; the greenhouse vegetables she produced allowed the emperor to eat fresh cucumbers in winter... By accident, she was transformed from a refugee fleeing famine to the general agricultural director of the Dajing Dynasty. Faced with the emperor's question of "a title or a bounty," Xu Zhixia wiped his face and just wanted to say: "Your Majesty, can we start with the water conservancy projects across the country? The irrigation efficiency is too low!
