Xu Changlin unexpectedly reincarnates in 1980. His originally intended fiancée, Su Bailu, runs away with the betrothal money, so he marries Su Banxia, the kindhearted but frail younger daughter of the Su family. Xu Changlin awakens a system and tames Boss Bai, a snow wolf king with humanlike intelligence. He ventures into the mountains to hunt and gather medicinal herbs while carefully caring for his wife, who suffers from a cough and asthma, and seeks precious medicinal ingredients to restore her health. With her family by her side, Su Banxia gradually recovers. Xu Changlin seizes an opportunity to lease the mountain forests and develops under-forest cultivation and livestock and poultry farming, leading his family to work hard and build a better life. Eventually, the family builds a brand-new brick-and-tile house, and Su Banxia becomes pregnant. Together, they live a stable, prosperous, and happy life among the mountains and forests.
