Modern young man Lu Fengnian transmigrates to Qingshigou in the 1960s. He decisively breaks off his engagement and relies on his intelligence and survival system to find food in the wilderness before discovering a new, compliant way to supply goods. He honors his mother, helps his older sister start a new life, and grows through his experiences at a state-run restaurant and a machinery repair factory, eventually becoming a procurement officer. Seeing that the villagers are still struggling to get enough to eat, he joins forces with village officials to explore emergency grain sources and collective farming. Leading everyone to support one another and work hard, he breathes new life into the small mountain village and finds sincere love along the way.
