Modern young man Wei Dashan travels through time to the Northern Frontier in 1981, where he saves Li Qing, a young educated woman who has been reborn. The two develop feelings for each other and decide to marry. Wei gains a lucky-husband ability, while Li possesses a treasure-hunting power. United in purpose, the couple venture into the mountains to catch fish, gather medicinal herbs, and hunt wild game, earning money through honest work and diligence. They treat others generously, care for relatives, friends, and neighbors, and leave behind their former acquaintance Liu Fang and her family, who judge people by wealth and status. Through their own hard work, they improve their living conditions and even help herders and factories solve their food supply problems. Together, they look forward to a stable and prosperous newlywed life, showing the beauty of striving and standing by each other.
