Roy was on top of a big and thick tree, hidden behind its leaves and branches, as his sense area was spread downward at the most of his capabilities.
From the moment he had developed his sense area, he didn't need to approach his target to spy on it, even if there was a 1-meter-thick wall in front of him, he didn't need to care about it.
Certainly, the thickness and the material of the wall interrupted his ability to spy across the wall, but that didn't matter now, as there was no wall in front of him, just leaves and branches.
But the moment that he heard the rumors amidst the soldiers he couldn't help but have an extremely weird and complicated expression on his face.
He probably would have never thought that this was possible, these guys were walking towards the cave in order to act as bait for the two Rank 5 beasts, and they understood that perfectly.
