“Two devices are placed side-by-side in the room. One is a restraint cage, the other a vacuum chamber. These two devices hint at two main characters today. Xiao Meng makes a stunning entrance wearing a full-body, zipperless latex suit. She’s incredibly cute, so much so that Xiao Yu, wearing a dark diving suit, couldn’t resist touching and admiring her body through the rubber suit. With Xiao Meng’s help, Xiao Yu enters the vacuum chamber, and then I personally lock Xiao Meng into the cage. One is restrained by the negative pressure of the vacuum, the other by a wooden collar and handcuffs; the two girls are unable to move. I first tickle them as a greeting, then cover their mouths on their rubber masks with my palm, performing a simple suffocation exercise. This is just a “warm-up” before the official start. After the preparations are complete, the two put on full-head gas masks. Xiao Meng’s mask has a mouth and nose shield; through the lenses, you can see her anxious, darting eyes. Komi’s mask had its inner layer removed, revealing her entire face clearly through the observation window. Next, a T-connector was connected to Komoe’s air intake, one end connected to Komi’s mask via a breathing tube, while the other end remained temporarily open. This made Komi’s “dead space” much larger than Komoe’s. Regardless of what restrictive device was connected to the open end, Komi was unable to breathe fresh air, and her breathing difficulties worsened. When the open end was completely sealed, the two entered an “air-sharing” state. Would their breathing rhythms synchronize? Or would they turn against each other to compete for the remaining oxygen? Changing the equipment brought another kind of fun. I first introduced an electric breathing valve. It would randomly open and close every 1 to 20 seconds. Although it was just a simple on/off mechanism, the carbon dioxide concentration on Komi’s side increased rapidly, and her breathing became noticeably heavier. Their breathing rhythms were completely out of sync; even with the valve open, they would still inhale each other’s exhaled air. After a while, I switched to a bubble bottle. From here on, the difficulty increased dramatically. If their breathing rhythms are completely opposite, they can’t generate enough negative pressure to draw fresh air into the hose, leading to a vicious cycle of constantly inhaling each other’s exhaust. Unsurprisingly, the bubbles in the bottle were chaotic and violently fluctuating, proving they weren’t a good match. Finally, it was time to switch to a 3-liter breathing bag. Even for one person, such a large dead space volume is nearing its limit. If they could breathe perfectly in sync, perhaps they could overcome this volume limitation, but that wasn’t the case. One person’s lungs became the other’s dead space, making their situation even more difficult than when they were alone. I didn’t wait long before completely shutting off the breathing bag valve. Now, in their world, only the breathing bag and the last bit of air in the hose remained. The breathing bag began to inflate and deflate erratically. Their gasps changed from suppressed groans to desperate screams and pleas. The game reached its climax and ended. Personally, I think the biggest highlight of this movie is seeing two girls, in the same life-or-death moment, go from increasingly violent gasps to final screams, and finally collapse. What do you think?’
