Hisshou Dungeon Un'ei Houhou

One day, on a sunny leisure day, a woman visited my house and asked me if was interested in managing a dungeon along with support offered from a goddess. But of course, I refused. Eh? I shouldn\'t ignore a person in trouble, moreover if it\'s beautiful woman? No way, that\'s too bothersome, why do I have to do that? I\'m perfectly satisfied with my comfortable life now, throwing it away is just overly s*upid… …sigh, fine, so it\'s go to another world, become a dungeon master, manage a dungeon and deal with the Mana circulation problem? Understood, but how to do it?
