Synopsis

The protagonist spends a considerable amount of money, earned from selling a down gem, on upgrading his labyrinth. This upgrade unlocks new facilities, including a Naga worker nest, and gives him six Naga workers to command. He sends them to explore and map the surrounding area, which they do surprisingly effectively, discovering old artifacts. Despite worrying about potential dangers and cost, the protagonist finds himself increasingly drawn to the labyrinth, understanding why people become obsessed with dungeon exploration.
