Arc in half hour have reached the place of that Ape destroying the walls to the outside.
He was keeping his distance from that monster as to not get its attention or die under the walls that were being destroyed.
When Arc was hiding behind a wall and peeking at the monster, he was caught off as wall he was hiding behind started to fall on Arc.
But, Arc quickly recovered from his carelessness and dodged the part of wall falling by moving to the side.
This was rock quite impact the bones of his shoulder, making few cracks on it. It was good that Arc don't have pain nerves or vocal cords, if he had them he would have been screaming his lungs out now.
Just then, this noise gained the attention of Ape monster as it started to move toward Arc's place with maddened red eyes.
