Conquering Otherworlds: Wherever My War Banner Flies Becomes Holy Land

After transmigrating to another world, Kuwen becomes the lord of Frostburn, the poorest territory in the Northern Lands. He awakens a War System: every battle he wins earns him experience, troops, resources, and technological rewards. From fifty guards to an army of a million, from a border town to an empire of steel. As the beastfolk march south, the undead rise again, the empire rots, and the church is shaken... Kuwen raises his battle standard. Wherever it flies becomes holy ground!
