NEVER.] This time, I let Xiaoyu-senpai describe the challenge herself, and it resulted in the following description: Today I was told that I would be undertaking a handcuff escape challenge—I would be blindfolded, have a plastic bag sealed over my head, and my hands would be cuffed behind my back. Only by obtaining the key to the handcuffs and fumbling to unlock them could I tear open the plastic bag. But how long could the air inside the bag sustain me? This challenge sounded both terrifying and exhilarating; I felt a mix of excitement and fear! Before the challenge, I went through three rounds of static warm-ups. This was to familiarize myself with the feeling of wearing handcuffs and locate the keyhole, and was also to gauge how long the air inside the bag could be breathed. The results were promising: I lasted about three minutes in the first two attempts, and in the third time, with a little push, I approached nearly four minutes. Should be enough time for me to unlock the handcuffs, right? The challenge began! In the first round, the key to the handcuffs was placed on the corner of a table. Wasn’t this a bit too easy? Carefully stepping ahead, turning, half crouching, I touched the corner of the table with my hands behind my back, and then I found the key. Unlocking was not a difficult task as I was already familiar with the keyhole position. So, after being sealed in the bag for two minutes, I freed myself. In the second round, the key was thrown on the ground, and I was directed to come over, sit down and search it. Darn, where’s the key? I seemed to have walked too far, and when I sat down, I inadvertently sat over the key. No wonder I couldn’t find it by searching the floor next to me. This consumed quite a bit of time, and it took me two minutes to get the key. My hands were already shaking, but luckily, I managed to complete the challenge with a bit of excitement but no danger. Apparently, oxygen is consumed more quickly when I was moving, and I shouldn’t expect that I could endure nearly four minutes like during the warm-up. Next came the most challenging final round. At this moment, my emotions were incredibly intense, a mix of anticipation and nervousness. I anticipated where the key would be placed by the master, but I was nervous about whether I may completely fail to find the key and rescue myself from this dire situation. Just as I was lost in thought, the final round began. The master quickly gave me instructions: the key is on the handrail of the stairs. What? How can a key be placed on this type of handrail? Before the game, I happened to observe this handrail, smooth and steep, with no designated position for placement. Shocked as I was, I immediately snapped out of it and walked towards the stairs. Time passed second by second, and the oxygen inside the bag diminished along with it. The difficulty of breathing increased gradually! In order to get the key on the handrail, I could only bend down, raise my hands cuffed behind me, and try to explore the location of the key bit by bit along the direction of the handrail. I tiptoed, twisted my hands into a position convenient for searching on the handrail, searching up and down several times. Fortunately, I finally found the key, but it seemed to be stuck. I didn’t have time to think too much and desperately pulled the key down. After this moment, my stamina was almost exhausted, the oxygen was almost depleted, and the carbon dioxide made me suffer. My body couldn’t hold on anymore. I slowly slid down and sit on the ground. Now that I had the key, if I persisted a little longer, I could open the handcuffs and be saved. But… where is the keyhole this time? Ah, the orientation of the handcuffs had changed this time, and the keyhole was not in its original position! I was very panicked, desperately trying to match the key with the keyhole but couldn’t get it right; I couldn’t unlock it! What should I do? At this point, I was already exhausted, and there was not enough oxygen. Chest tightness, dizziness, weakness in limbs, and… desperately wanting to breathe oxygen but there was none to inhale! I couldn’t stand it, started shouting and struggling desperately, shouting for help again and again, but no one came to rescue me! I felt endless pain and despair, screaming loudly, holding on to the last glimmer of hope until darkness occupied my vision… the next moment, I found myself lying on the ground, the bag had been opened, and my mind couldn’t calm down for a long time.
