Lin Yue, a graduate student in the Department of History, accidentally traveled to the northern border of the fictional Dayong Dynasty and became the young village head of the barren Shiwa Village. At that time, the village was trapped in a blizzard and famine. There was danger of barbarian plundering outside, and the suffering of exploitation by grain merchants inside. In addition, the court was corrupt and taxes were heavy. The desperate situation of survival was close at hand.
Relying on modern knowledge and historical wisdom, Lin Yue first stabilized the internal affairs—distributing grain, repairing houses, forming a village protection team, and gathering the strength of the villagers; then he defeated foreign aggression—deterring the grain merchants with his resourcefulness, resisting the barbarians with his courage, and giving Shiwa Village a breathing space. From then on, he worked step by step, prospering villages through trade, strengthening his foundation with institutions, gradually annexing surrounding forces, and carving out a world in the northern border.
