Crawl down the vent

You shuffle your way through the vent. The vent is made out of cold steel plating, is only about 2 feet high, and 3 feet wide at some parts. You're **** to wriggle your way through, the cold steel pressing up against your naked body. Carrying the knife only makes the process slower, as you need to take care to not cut yourself.

After a long, miserable 45 minutes of crawling, you see a dim light at the end. You pop out into a small room, connected to all kinds of doors and hallways. You appear to be in one of the outer labs. You need to make your way to room #24, and find the vent leading down to the next floor.

The room is dimly lit, as are the hallways. You clutch your knife in your hand, and swallow. This was it. If you were to save everyone from a horrible fate as slaves, you would have to succeed where so many others failed. The only problem was, you didn't know WHY they failed. You needed to overcome that obstacle. Ryuko had sacrificed herself for you. If you fell here, she'd be transformed into one of Alex's experiments for sure. She might have been purchased, but there was no way Alex would let her off so easily. Failure, was not an option for you.

You look down at the ground. There were a few sets of clothing scattered about. You assumed that Alex's experiments sometimes sat in wait here for maiden's to come down the shaft. You thanked the stars you were not one of these maidens.

You walked over to a set of clothing you recognized. A white vest-like shirt with a blue cross, along with a blue skirt and brown belt. There was no sign of panties or bra anywhere, however. The monster must have removed it later. You recognized these clothes as Lucy's. She was a rather normal girl, always friendly, and always embarrassed about her large cup size. You knew she had already fallen victim to the dungeon two weeks ago, but still you felt a twinge of deep sadness. [Lucy Heartfilia, Fairy Tail]

You picked up a different bra, and a different pair of panties and put them on. They were light blue. You picked up Lucy's clothing, and put it on. It was a slim chance, but you felt that maybe wearing clothes might make the experiments want you as badly. At the very least, you felt a little less embarrassed, even if no one else was around.

You looked around the room. There were two ways to go. Left, and right.

To your left, there was a fairly empty hallway. The lights were flickering, and you spotted an overturned plant pot. The floor appeared to be well-worn, suggesting that many things had come and gone this way.

To your right, there was another lit hallway. It was well lit and completely empty, aside from a few strange articles of clothing. The floor appeared to be only slightly worn out.
