When special forces soldier Li Mu unexpectedly dies while carrying out a mission, he is reborn in 1959 as a poor young man with the same name. His parents passed away when he was very young, leaving him and his little sister to depend on each other. Food is scarce in the village, and every meal consists of barely anything. His little sister often cries from hunger, while Li Mu himself suffers from edema due to malnutrition. At this desperate moment, the portable spiritual spring space he brought with him quietly awakens. From then on, the siblings rely on this miraculous space to live securely, working hard step by step to improve their lives.
