Modern supermarket employee Liu Dazhuang accidentally time-travels to the material-scarce 1960s, awakening a spatial supermarket with automatic restocking. Using the space, he takes out fish, meat, and food to improve his family's life, seizes the opportunity to become a textile mill procurement officer, and purchases a courtyard house in the city. The family moves to the city, resolves difficulties regarding jobs and children's schooling, gets along well with neighbors, holds massive supplies in their hands, guards his family in the hard times, and opens a new life of abundance and stability.
