"What was that noise?" Asked Nova as she walked a few places ahead and turned the lane along with Cheron to see no one and nothing that could have causes that loud bang.
"I don't know. It was so loud but nothing was visible. It was as if everything was normal." Said Cygnus.
"It can't be normal. It's cant be some small mice roaming around the caves. It was way too loud for that. We must run away, not towards it." Said Leonard as he jumped from one feet to another.
"Let's run then what are we all waiting for?" Said Tris and behind him ran everyone else. They aimlessly ran away from the spot and kept up the pace until each one of them was panting heavily.
"Why are we running? What if it was nothing, just done rock fell or something." Said Paula and everyone stopped to consider it for a second when they heard again, the same sound, but this time more long tone and with that it sounded much closer.
