In 1983, heavy snow blankets the Greater Khingan Mountains, sealing off the mountain trails. Lin Yi, a retired soldier and former king of the battlefield, is reborn. After his three-and-a-half-year-old little sister steals some sacrificial meat, his stepmother incites his biological father to kick them out of the family. At the end of his rope, Lin Yi unexpectedly awakens a portable freshness-preserving space and takes his little sister into the mountains to make a living. With his formidable skills from his previous life and his little sister's incredible luck, Lin Yi hunts game, gathers wild ginseng, stockpiles mountain produce, and ventures into the marketplace, gradually improving their lives. Starting with nothing, he eventually builds a new house and becomes a prosperous man. Not only does he spoil his little sister rotten, but he also makes the relatives who once bullied them regret their actions. When his biological father and stepmother come crawling back, hoping to reconcile, Lin Yi firmly refuses. Now that their family ties have been severed, they will each go their own way for the rest of their lives!
