All Geniuses

Grey looked at those in front of him with a gloomy expression. 

They were currently in a forest, and although they weren't really going all out, he was currently in a sorry state. 

Klaus had an evil grin on his face as he saw Grey's condition, he laughed, "Weren't you smug earlier?" 

"Why don't you take me one on one since you're so powerful?" Grey mocked. 

Klaus didn't seem fazed by his words and said shamelessly, "I also want the others to enjoy beating you up as well. If not, I'd have beaten you up alone. Don't worry, after today, I won't beat you up again." 

Grey wanted to convince the others but Klaus didn't give him the opportunity to say anything, "Why are you guys staring, do you want him to complete his array?" 

"F*ck! Bastard!" Grey cursed. 

When talking to them, he was secretly preparing an array, he never thought that Klaus would be the one to sense it.
