"If I'm not wrong, you have some artifact that lets you see how strong someone is, right?" Nix asked, his expression turning calm, as though his strongest underling hadn't just been killed.

"Oh? Why do you think so?" Max asked, again surprised.

"It's not too hard to guess seeing how you went after the second strongest in my group. If I'm not wrong, two of your companions should be early-stage four-star mages who you intend to take care of my two early-stage four-star demons, right?" 

Nix said, his darting over to Emily and the elves.

Emily looked at Max's back in surprise and thought, 'No wonder he directly went in for the kill.' 

The elves were also surprised upon hearing that Max could see how strong someone was, because such an artifact that let you do it, were not common. They also felt relieved because Max didn't look worried right now, meaning he believed they could handle the demons.

However, Nix's next sentence made them freeze.
