Lin Jianjun, a modern ordinary social worker, accidentally traveled to a village in the north where there was a serious famine in 1960, and became a boy with the same name and the same surname, who was about to starve to death. It is bound to the "Survival Mutual Aid System" - a portable space that can store items, has its own small black soil (which can accelerate planting) and micro-circulating water sources (can raise fish/shrimp). The system tasks revolve around "keeping the family alive and eating well", and the rewards are linked to food/survival materials.
