Amazing slave seal

"So, you really took him as your slave." He said,

Quinn shuddered at his gaze and instinctively moved behind Max for protection, even though he doubted that if this elf wanted to kill him, even he wouldn't be able to save him. The elf was almost as strong as his team leader, after all.

Max ignored his killing intent and calmly nodded. "Yeah. He will be more useful to us than dead."

The elf leader shifted his gaze from Quinn to Max and frowned. "Are you thinking of him using as a spy? If yes, then you should forget about it."

"Why is that?" Max asked, curious.

"Because the demons could easily check if someone is branded with a slave seal or not, and if I'm not wrong, each time they return to their camp, they should be checked." Saying this, he glared at Quinn. "Isn't it right?"

"Y-Yes. That's right." Quinn nodded.

"Is that the only reason?" Max asked. He didn't look even a bit bothered by this revelation.
