A down-on-his-luck nobody from the twenty-first century suddenly transmigrates to an unfamiliar continent and begins a new life. Yang Xiaodong transmigrates to a remote border town in the Great Xi Empire, a place much like Gansu in China. Its only purpose is to guard the frontier, and guard the frontier. The Great Xi is comparable to the Northern Song era: the Central Plains are prosperous, but enemies surround them. The Jurchen are in the northeast, the Mongols in the north, and the Uyghurs in the northwest. Yang Xiaodong is stationed in Fenglin Town, a small outpost in the northwest. Faced with such a harsh environment, all he can do is laugh it off.
