That Time I Reincarnated as a Dungeon Master. (dead on webnovel)

“Randomly being pulled into a meeting of goddess was the last thing I expected. I don’t remember much from my previous life, I just remember endless darkness. So of course I asked for information on what ever World I was going to. And then I let the Goddess decide. I have no clue how it happened, but I ended up as a dungeon master in the world of ‘that time I reincarnated as a slime.’”
