Special forces member Li Mu died unexpectedly while performing a mission and was reborn in 1959 as a poor boy with the same name. The original parents passed away early, leaving only the young sister to depend on each other. Food rations are in short supply in the village, and there is very little food for each meal. His sister often cries from hunger, and Li Mu himself is also swollen due to lack of food. In times of crisis, the portable spiritual space that they brought with them quietly awakened. From then on, the brother and sister relied on the space to live a stable life, working hard to improve their lives step by step.
