Seeing the two people casually walking toward them, after instant-killing an early-stage Arch rank magic beast, the guard who was holding up the banner, tensed up, earlier he watched Daimon overpowering the other six experts, but that was because of a difference in speed.
Assassin type mages were quite strong against other humans, but against magic beasts they were at disadvantage, but then the masked solver haired man just killed that sandworm in a mere couple of seconds.
And the previous scene of the same silver haired masked man, killing someone over a small dispute was still fresh, so who knows what could happen now.
Also, it's worth mentioning that the other guards who were all early-stage Lord ranks, were in shock, not only at Daimon's performance, but at the banner with the yellow sword and blue shield that their boss was holding in his hands right now.
