While the Ember Crows were leisurely wasting their time, out of nowhere, a human shaped rock flew toward their lines and then it crushed one of them to death. The crows suddenly began to make noises while looking around and searching for the enemies, but they found nothing. Despite that, a good number of them left their line of defense to look for the one who attacked their ally. Because of the numerous rocks around, they had to fly in circles in many spots, but they found nothing. They got confused since that was something that they had experienced before... not like they had many chances of learn and experience many things.
