The scene was still clear in his mind, where five of them had attacked Elias together. Thirty seconds... That's all it took for the boy to take them down, and that's when he didn't even move from his place or use any abilities.
From the start to the end, they didn't even know how they were beaten. All they remembered was the pain, and the coldness on his face when their Summoned Beasts were dying.
"You killed my Summoned Beast! Did you really think these shabby shackles could restrict me? I might not be as strong as you, but if I want to leave, you won't be able to stop me in this closed space!"
The boy pulled his hands to break the shackles that had tied his hands. The shackles looked ordinary, made from cheap iron. Even if he had lost his summoned beast, he was still strong enough to break it.
