I Build ANYTHING—Dragon Nests, Demon Gates, Hero Altars—So When Demons Invaded, My Army Was Ready!

What the story is about

Lin Yu awakens as a seemingly useless God-grade Builder, a profession that lets him construct buildings in a private territory, recruit monster units, and gain a share of their combat power. Mocked and underestimated, he secretly builds an army and scavenges dungeon resources while navigating academy rivalries, dangerous portals, and a growing feud with powerful families.
