Lin Xuan, a PhD in agricultural science, unexpectedly finds himself reincarnated as a nobleman sentenced to exile in the far north. Faced with blizzards and famine, he refuses to give in. Using his modern scientific knowledge, he leads the villagers of Desolate Land Village in building heated brick beds, constructing greenhouses, and growing cassava, fighting to survive amid the ice and snow. After overcoming the crisis, he uses his wisdom to restore order and builds earthen fortifications to defend their home. When the injustice against his family is finally overturned, Lin Xuan turns down the wealth and glory of returning to the capital and chooses to remain on the frontier to cultivate the land. Taking root in the wilderness, he teaches the people how to farm and gradually transforms this once-frozen wasteland into a prosperous paradise beyond the frontier, where everyone has enough food and clothing. With everything he has learned, he quietly safeguards the peace and well-being of the people.
