Ibro started to attack them with his sword. He didn't use any skill at all as his simple attack could take nearly one-eighth of their HP.
He wasn't suppressing his powers anymore, so his sword was moving so rapidly that it created shadows from its extreme speed. Although these monsters kept falling one after another that horn never stopped sounding even for a second.
At the same time, these monsters never tried to defend themselves even for a second. They didn't even try to dodge his attacks. Although he was attacking very seriously, that situation seemed weird.
After he killed the last monster, he stood in his place and looked around in surprise. All the area around him which was empty a minute ago was now filled by many monsters teams.
Ibro wasn't really surprised by their appearance, as he was informed by Dronil about their approach. What caused his surprise was what these monsters did.
