Rein and Sophia started investigating this region very carefully. As Rein did not have any abilities which he could use for scouting or hiding, he allowed Sophia, an expert in this field to lead the way. He was there to mainly check the strength and fighting ability of the monsters here and Sophia was checking how strong the sense of these monsters were.
The very first thing that they noticed only after a few minutes since they started the investigation was the fact that, most of the monsters living in the Ashen Barrens were actually adept at hiding and ambushing. Very few monsters were directly outside in the plain view.
That made a lot of sense though as this place was completely open so it was possible for someone to see very far here. So if any monsters were outside in plain view, then that monster would just be an easy prey for others to feast on. So to survive here, most of the monsters were experts in the art hiding themselves and ambushing their prey.
