It was a mountain.
Well, it wasn't exactly a mountain, but it was a large pile of rocks that was in the center of this room.
This monster was completely covered in rocks and looked more like it was just a pile of inanimate rocks than anything, but if one looked closely, they would be able to see the hide that was underneath.
It seemed that there was a layer of rocks that formed a shell on this thing's back while the underside wasn't covered by anything.
As soon as I saw this, I could guess what kind of animal it was.
It was some kind of armadillo.
Though I didn't really know what the name of this monster was, I just temporarily named it rock armadillo in my mind.
But judging by the aura that was coming from it, it was clear that this thing wasn't weak.
With my experience, I could guess that this thing should be around C Rank.
First a bunch of E Ranked Monsters, then a bunch of D Ranked Monsters, and now a C Rank Monster…
