Five Dynasties: Map of Mountains and Rivers

Also known as "Fifth Generation: My GIS System Can Change the Country" Chen Yan was at the Santiao field site in Cangzhou, Hebei, when the blown-up server was blasted into the mass grave of the Fifth Generation. A Khitan soldier stabbed him in the back of his head. In his arms there was only a red cloth shoe that the child bride had embroidered for his daughter. His stomach was so empty that it could hold a stone. Next to him was a broken coffin that was frozen solid. Others rely on knives to survive in troubled times, but Chen Yan relies on GIS to survive - a layer of light blue grid floats in his field of vision, which is the embodiment of the professional memory accumulated during the land survey in the first half of his life: Looking at the saline-alkali land, he can mark the salt content and pH. He can grow winter wheat with a yield of nine bushels per acre on waste land that others despise; Looking at the terrain, he can calculate the slope and the amount of earthwork. Others would have to die for three thousand people to build the city wall, but he could draw a line and save half the work; Based on the enemy's situation, he could mark the heat source and movement trajectory. When dozens of broken soldiers approached, he dug the trap half an hour in advance. At the beginning, he hid from defeated soldiers in the mass graves, relied on the grid to find gray vegetables in the shade and unfrozen springs, and made a deal with Shatuo veteran Jiao Laoqi to form a "yizhuang team" of four old, weak, sick and disabled people. Starting from the saline-alkali land in Weibo, we improved the soil, cleared the land, built a security guard, and implemented work points, turning the refugee den into an iron barrel granary in troubled times. Others say that troubled times are the stage for heroes. Chen Yan squatted on the ridge of the field and gnawed steamed buns: "What is not heroic is to measure the land first and let the people have food in their bowls. That is better than anything else."
