In 1962, during a devastating famine, Xu An transmigrates into the body of a frail villager in Kaoshantun and activates a "Pinduoduo Meal" system that provides food. When his exploitative parents-in-law try to seize his grain and sell his wife, Su Wan, and his younger sister-in-law, Su Xiaoyue, to the Zhao family in exchange for food, Xu An steps forward to protect them, fearlessly taking up his hunting rifle. Through his hunting skills, contributions of game, and discovery of clues to a water source, he earns the production team's support. When the Su and Zhao families collude to break into his home and abduct the women, Xu An fires a warning shot to intimidate the bully Zhao Lao'er, cleverly turns the collective's rules against the villains, and uncovers the mystery surrounding Su Wan's origins. Armed with his system and his wits, Xu An turns his fortunes around and builds a prosperous life.
