Arvin's heart was beating faster and faster. He knew that his cover would be blown as soon the people behind him would see the area where he was lying. After all only an idiot would not be able to recognize a sand color blanket lying on the ground. Arvin didn't know whether these people would be hostile or not. But he didn't want to take any chances. He took his kunai knives. He thought when these guys would come closer he would come out and pounce at everyone.
Arvin was waiting for the right moment, but that moment never came. As Arvin was lying he heard an explosion. He then sensed the people that were coming towards him started running towards the explosion.
