Traveling back to a year of severe drought, Lin Zhixia started off in hellish mode: the whole family only had half a bag of moldy brown rice, and there were a group of homeless people outside the door who were eager to steal the food. There is no system, no space, not even a golden finger. Lin Zhixia looked at the hoe in her hand and sighed: These days, I can only dig food by myself. The good news is that in her previous life, she was a hard-core Ph. D. From an agricultural university, and farming was her professional counterpart; the bad news is that in this troubled world, growing food is only the first step, and preserving food is the real life and death situation. In order to protect the newly cultivated fertile land, Lin Zhixia started a dual career of "farming + fortification". During the day, she led the villagers to cultivate long acres, improve irrigation, and vowed to turn barren hills into fertile fields; at night, she transformed into a "defense master", digging traps and setting up secret posts around the granary, and even trained the old, weak, sick and disabled in the village into a militia squad. When the bandits sneaked into the village in the dark again, what greeted them were not weak villagers, but overwhelming lime powder, dense animal traps, and Lin Zhixia's smiling face: "Everyone, how is the 'security experience' in our village? If you are satisfied, can you leave the toll before leaving?" From then on, this barren wasteland became the most "safe" place in the ten miles and eight villages. The rogue bandits were frightened when they heard the news, and the government looked at him with admiration. Lin Zhixia looked at the mountains of grain piled up in the granary and wiped the sweat from her forehead: "Farming requires not only a good harvest, but also learning how to turn these grains into capital that others will not dare to do."
