"Who are you…?"
The forest green humanoid demon was adamant in asking that question because of the things that he had seen with his own eyes a few moments ago before the dark earth dome erected and closed him off with the jet-black humanoid demon inside it.
It was because of the rune formations that he saw the jet-black humanoid demon grab from his pouch before throwing them to the ground to erect the huge dome in a matter of seconds.
The only ways the jet-black humanoid demon was able to use those rune formations were either he was a runemaster himself which was unlikely or he was given those rune formations from a runemaster which was more likely considering the fact that they were currently in the first demon realm.
