With how big this forest was along with the huge black trees that reached over 100 meters(330ft) in height and completely blocked everyone's vision, it was only natural that most outer disciples would struggle to locate specific magic beasts in this place.
This was even more so for those disciples that had no idea about the environment that each magic beast chose to live in or the habits that those beasts naturally had.
They would most likely end up looking for days, or perhaps even weeks without finding the magic beast that they were looking for.
After all, hunting specific middle rank 5 magic beasts was completely different from hunting any random middle rank 5 beast.
The first required knowledge of that certain magic beast, that was on par with that of most beast tamers', and wasn't something that any random disciple could do at a whim.
