No, it's a dungeon. ... A young man from earth has found himself reincarnated as a dungeon. In this new world, he is now but a child. Armed with nothing else but his genius creation capability, come watch him as he struggles to survive this world where his kind are treated as nothing but tools. "Hmm? Another group of adventurers is sent to close me down?" He laughed. "Clearly, they didn't understand when i killed all of their armies... wait, that boy has a good looking soul. Why don't I turn him into a slime?" From the deepest pits of the dungeons, terrifying creatures awoke as they had been ordered by the creature they live in. Be the strongest dragons living in the deepest levels of the dungeon, to the weakest goblins only known for being cannon fodder.
