I Became a Dungeon

A shut-in gaming addict stayed up all night playing games and died suddenly. His soul became attached to the core of a dungeon in a game.

He had to worry about getting mercilessly farmed for loot by players, while also fearing that the Abyss or the devils might discover him and destroy him.

Truly caught between a rock and a hard place!

But after managing to lie low for a long time, he discovers that this game world is not so simple!

P.S. This only has dungeon elements and has little to do with any known games.
