Introduction: One day in a sunny leisure day, a woman visited my house and asked me if I’m interested in managing a dungeon along with support offer from goddess. But of course, I refused.Eh? I shouldn’t ignore person in trouble, moreover if it’s 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?...
