Ivan lifted his hands with excitement on his face, showing off his blackish-gray stone shell with hints of red on it, and asked Gemina, "Dear, do you think that my new shell is pretty?"
After eating two crayfish in that afternoon, his shell—which had been dormant for the past five, six years—finally broke away and changed into this new one.
This also meant that he had broken through successfully, and became a 4th-tier rock troll.
Although there was only a difference of one tier between the 3rd-tier and 4th-tier, it was the natural barrier in between a low-tier and a mid-tier demon.
Low-tier demons were looked down upon no matter where they went, but mid-tier demons would be recruited by some demon islands, and received a recognized identity.
