As Noel said, they began marching forward, killing all the demons they could find. There was a reason why they spared no one. Noel deemed it would be troublesome if there was a demon sneaking up on them whether it happened in this valley or when they encountered the hermit. Hence, it was decided to kill all demons even if they looked weak and unable to fight back.
They met the other two Superior Demons. But due to their coordination, they managed to kill them one by one, allowing them to emerge unscathed.
Though, killing all these demons took more than a day because they had to repeatedly recover their Spiritual Energy.
Before going inside the cave, they decided to make a camp where they conditioned themselves to their peak so that they could fight the hermit if it was necessary.
"Are you ready for tomorrow, Noel?" Anna asked while sitting next to him.
"Yeah." Noel nodded.
"How confident are you that the hermit won't attack us?"
