The last Floor (a)
Vincent entered the second floor of the monster tower. It was dark the moment he entered it. However, an instant later, it began to brighten up in dim fiery lights. He was finally able to take in his surroundings more clearly. He was in a corridor of some sort, and above him, bulbs were hanging from the ceilings, attached to thin wires.
Some of them weren't working; Some of them were blinking every one or two seconds, something he found disturbing; Some of them were releasing intense rays of light, and they were the main source of light, acting as the brightest source of illumination.
Thick metallic plating coated the walls, floor, and ceiling, making them appear sturdy and unbreakable.
Just as he finished determining where he had appeared in the monster tower, he heard something that sounded like a whistle.
