When he heard the question, Benjamin began to panic.
Damn!
Before he could hesitate, he started an incantation so he could be ready to subdue the knife-scarred man with magic in the shortest time.
What the man said was enough to ruin the whole plan.
Actually, regardless of what the knife-scarred man found out, Benjamin should be able to deal with it. For him to discover the gun was part of Benjamin’s plan, since it will lower the man’s suspicion.
But the knife-scarred man somehow found out that he was a mage.
Magic was Benjamin’s trump card, if it was revealed, Benjamin’s situation would be reduced from infinite possibilities to him just hanging onto a single thread of luck. At this moment he could only start an incantation and pray in his heart that the knife-scarred man would not have time to react just after discovering his identity. Otherwise, he might have fallen directly for that man’s trap.
Luckily, it looks like the knife-scarred man had only just found out the truth.
