"D-Don't you know it's a capital offense for killing an imperial guard," Konner stuttered as sweat continued trickling down his forehead.
Konner was frightened by Zen's ruthless and decisive action as he hoped to stall for a bit more time.
Even if he knows the word he just utter has no effect on Zen, any little bit of time he stalled, is a time he saved enough to save his pathetic life.
Thus, he decided to risk it all and explain something for Zen to stall longer.
"Hmph, just wait till the other imperial guard sees this barrier you cast. You're an ignorant and impulsive young man. By casting that barrier, you have already alerted everyone about your entry," Konner sneered loudly, hoping to make Zen rethink his decision on attacking any further.
Meanwhile, Zen was slightly surprised by the information and decided to ask Cecilia if his words were true.
