In the winter of 1983, Chen Chuan, who had once destroyed his family through alcoholism and gambling and caused his childhood friend's tragic death, is reborn on the day he returns to the Su family to settle a debt. Leaving his troubled past behind, he promises to repay the debt within seven days. Drawing on thirty years of hunting experience from his previous life, he takes his childhood friend into the snowy mountains, where hunting creatures grants him their innate abilities. Using traditional hunting techniques, he hunts beasts to earn money, repay the debt, and support his family. He also leads the entire village in establishing a mountain-hunting mutual aid group, battling unscrupulous merchants while gradually making amends for the family bonds he once betrayed by keeping his promises time and again.
