Hisshou Dungeon Unei Houhou

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