Even with his skill activated throughout the entire night, Dustin could sense a single thing. All the monsters really did leave for some clan meeting or something, it was just too weird.
The following day when everyone was up, Dustin led the whole team out of the volcanic region. Throughout the small journey, nothing very eventful happened. There was an attack from a monster, but it was just a D rank monster, and Dustin made quick work of it. After that, two more D rank monsters of the same kind attacked, and the same, Dustin took care of it easily.
After a day of travelling or close to it, Dustin brought the entire team out of the volcanic region safely without any extra casualties. From there they part ways, and Dustin returned back into the volcanic region. He could have used the wyvern, but for whatever reason, and with a little hope that maybe their large numbers would attract a monster or beast, he didn't. In the end nothing happened.
