Exploring A Dangerous Dungeon

-----

In front of us, the entrance to the E+ Rank Dungeon "Ogre's Den" was open. Dungeons in the Stronghold City are maintained by the Academy itself and are used by their students and professors for both growing stronger and farming materials and even equipment that sometimes drops from the dungeon's monsters or bosses. The low rank dungeons are simple in structure, usually being in either the shape of a large cave or a labyrinth ruin.
