Duran started to approach the area where he saw the movement happen on the ground while Rean stayed as still as a rock. With his Light bending skill, it really looked like the place was completely empty. However, Duran was sure he had seen something moving there a while ago.
Because of Kila, a Stage Nine Demon Beast, all the other demon beasts in the vicinity had fled. Other than the damaged area, there shouldn't be any movement, especially in the place Rean moved in. Rean was also cursing at himself, thinking that he should have waited for Duran to leave before he tried to do so as well.
Duran then landed right in front of Rean and looked around as he narrowed his eyes, muttering to himself with a tone of suspicion, "Weird...was it just my imagination?"
Rean was happy to hear that, inwardly shouting, 'Yes, it was just your imagination! Now, go away!'
