Levelling Up In An Exclusive Dungeon

There’s not a lot of hunting grounds, but there are too many hunters!
It’s a difficult world to catch monsters if you don’t have money or connections.
As I was washing my hands one day, a dungeon suddenly appeared in front of me.
The dungeon was right in my loft!
I’ll become stronger by monopolizing EXP and rewards in my dungeon that only I know of!
