The whole team was out of food, and bandits were blocking the road. How could she, a homeless widow who died of starvation, lead others to survive? Shen Qinghe, a modern agricultural scientist, traveled to the last years of the Yan Dynasty and became the most inconspicuous widow among the people fleeing famine. Natural disasters continue year after year, warlords separatist regimes, and people everywhere starve and die. Fortunately, she has the space she carries with her - a spiritual spring of running water, three acres of spiritual land, and a collection of agricultural and industrial books, which are the only trump cards in a desperate situation. From finding food, building canals, and clearing wasteland, to building villages, garrisoning fields, training troops, and setting up mansions, she gathered refugees into common people and planted barren grains into cities. Warlords were snatching food, aristocratic families were blocking roads, and cavalry from the north were pressing down from the south. Everyone thought she wouldn't be able to survive the winter. But later, the remnants of the Manchu Dynasty knelt down and begged for help, and millions of refugees only recognized her. Who should be named in this world?
