Chapter 656: Elemental Rune!

In fending off the Demons' attack, Rocky had slain two high-level Demons, and of course, he paid a hefty price for it. The White Demon Armor was once again scrapped, and he had suffered serious injuries that kept him in bed for half a month. However, the spoils from this battle were enormous – he acquired the materials of two high-level Demons!

Among these two high-level Demons, one was a Steel Fury Demon, similar to the first Grayrock Demon slain by Rocky but made, not of stone, but of real metal. This metal is unique in the world, found only in Steel Fury Demons, and is one of the top materials.
