Hisshou Dungeon Unei Houhou

One sunny leisurely day, a woman visited my house and asked me if I were interested in managing a dungeon along with support from goddess.

But of course, I refused. Eh? Shouldn't I 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 go to another world, become a dungeon master, manage a dungeon and deal with the Mana circulation problem? Understood, but how to do it?
