For a while, Quinn inspected the shell, and he could see it was in perfect condition.
He walked back to the others after punching the black turtle shell and could see Sunny giving him a wink. It was obvious to her what Quinn had done, and she thought it was the right decision.
It was best for the Turtle not to know of Quinn's strength. Otherwise, perhaps the Turtle would try to find someone with similar strength as Quinn, complaining about how the undead king had managed to find someone so powerful.
Then they really would have been at a loss. She was just thankful that Quinn hadn't attempted to show off in that situation. Still, those who needed to take part in the test now were a little nervous.
"I would suggest that each of you hit that shell as hard as you can; otherwise, you will have a hard time breaking it," Quinn commented. He had felt it with his own hands, and the truth was, he would have liked to test if he could actually break it or not.
