The Sound Of An Echo
Christopher took out his flashlight and pointed it directly and straightly outward, but he could not see anything nor the end of the tunnel. He was thinking that someone is in there or something else. Just right after he did that, he then heard echoing sounds from the father part of the tunnel. He, obviously, continued to walk to confirm what was the source of the noise he just heard.
The Sound Of An Echo
No Light, No Warmth
Christopher decided to go further down the tunnel to confirm what is the source of the noise. While doing so, he realized that there was no air movement inside, no warmth, and no light. He was holding his flashlight like he was about to go on a battlefield and he was holding a weapon. As he came closer to the end, the noise grew louder. He could hear the sound of metal and machinery.
No Light, No Warmth
