Modern young man Jiang Chen unexpectedly travels through time to an era of famine. His original counterpart was a wastrel who squandered the family's possessions to please his fiancée. He carries a mobile phone that can predict resources in the mountains and forests, as well as in towns. Using his foreknowledge, he hunts, gathers medicinal herbs, searches for treasures, and accumulates money and food before decisively breaking away from his greedy fiancée and her family. Along the way, he counters the village headman and schemers secretly plotting against his family, fortuitously learns Thunderclap Fist, and meets the down-and-out talented woman Shen Yanqiu, with whom he gradually falls in love. Jiang treats his family well and brings home meat every day, ensuring that his impoverished household stays well-fed and comfortable even during the famine. Meanwhile, he steadily grows stronger to face the many dangers lurking in the mountains, including the wolf king.
