Noah dug a hole in the rocky corridor.
He made it two cubic meters large to be comfortable, he didn't plan on to leave it any time soon.
He resumed his usual training schedule, waiting in the darkness of the hole for a bat to pass by.
When the night arrived and the leader sent the order, the hundreds of rank 1 and rank 2 beasts of its pack left the central area and moved to the surface.
One of the rank 2 specimens felt its body being squeezed and was dragged into one of the cavities of the corridor.
Noah directly stabbed the beast on its chest, killing it on the spot, no one of its pack noticed its disappearance.
Noah carefully looked at the bat, giving importance to the details of its body.
He took out Uriah's diary and opened it where the sketches were.
After evaluating a bit in his mind, he began to draw on the ground the image of the dead bat in front of him.
