Pei Ce, the commander of a modern retired special operations battalion, unexpectedly traveled to a war-torn fictional world and became a down-and-out military commander in a small border town. He awakened to the territory management system and did not need extra companions. He relied on his own battlefield experience to complete the tasks of expanding land, training troops, and reassuring the people issued by the system. He gradually gathered the refugees, repelled surrounding bandits and enemies, and turned the dilapidated border stronghold into a unique and stable territory in the troubled times.
