Spelunking

Three newly minted miners and one aspiring supervisor slash ore detector discovered how to get rich overnight.

None of them knew what to expect, especially Ollie, who couldn't detect ores and had no idea that an entire mine could exist in a spatial dimension.

Technically, it couldn't, but since when was this Dungeon a normal space?

Luca knew about the resources found in each dungeon, and the higher the level of the dungeon, the better the resources. He just didn't expect this one to keep everything intact after being cleared.

In fact, it was so intact that even life forms could be preserved, but that was for a different time.

More pressing was Ollie's project submission, which dictated his right to stay in the academy.

Luca knew better than to expect to find anything by the mouth of the cave and decided to go spelunking based on D-29's directions.
