A modern youth accidentally time-travels to become a ten-year-old orphan Zhou Ningye, and at the very beginning is beaten to within an inch of his life by his vicious aunt-in-law. Having finally waited for an immortal cultivation system, the system discovers it bound the wrong world, hastily unbinds, and leaves him with only a mysterious space and two bottles of pills. Facing his seven-year-old younger brother, young younger sister, and infant youngest sister, Zhou Ningye can only shoulder the responsibility of an eldest brother, starting from digging wild vegetables, picking mushrooms, and selling mountain goods, earning grain to support the family bit by bit. Yet the toxic relatives are still coveting the real estate left behind by his parents, and even want to sell his younger sister.
