Dungeon from Scratch

When I woke up, I became the new lord of a ruined dungeon in a different world. There are no plug-ins, no demon army, only a few starving goblins under his command, and half of the dungeon has collapsed. In order to survive, I can only start by repairing traps, finding food, clearing the ruins, rebuilding the dungeon bit by bit, and picking up those guys who have nowhere to go one by one. But when the dungeon finally began to "come alive", I discovered that the real trouble was never just hunger and ruins. This is a story about running a dungeon from scratch, recruiting companions, and gradually growing into a lord.
