Arriving 5 kilometers away from their targets, Lothur's group slowed down, first noticing the positions of the 3 demons they were about to attack.
The only ones in the area that weren't completely hidden were the demons. They even camouflaged their auras, but that wasn't enough to hide them from Lothur.
He could easily detect their demonic aura!
Sensing those level 22 individuals from a distance, the group was already observing them.
However, level 22 and 23 observers were in the area, all of whom hid their positions and auras. Lothur's group couldn't easily sense these stronger ones because the way they hid their auras was very effective against cultivators like those in his group.
