Going in
As they entered the tunnel, they had their flashlights on but they couldn’t see any end in sight. They were just going down some stairs that seemed to be leading them to nowhere. But that didn’t make any sense. Why would someone build any of this in the first place in the woods?
The tunnel kept going deeper underground and the three men were cautiously moving forward. They had no idea what to expect and were slightly scared to see what was going to be at the end. Maybe, it would just be a secret entrance to the house from a different location on the mountain?
