Xiaoyu-senpai wants to try anaerobic exercise because she’s into fitness. After wearing a breathplay hood with no breathing hole, she did a plank plus rest without taking off the hood, and repeated this for two more times. The set time for each group increased gradually. In the last round, the timer for rest was wrongly set as counting up instead of counting down. Poor Xiaoyu was waiting for the alarm beep when the countdown ends, which will never happen. When I discovered that error, Xiaoyu had already collapsed on the ground, her lips turned purple, and she was twitching slightly... Next was a set of squats for more than two minutes. Although panting heavily, Xiaoyu still finished it successfully. Before the next exercise, she needed a good rest, so I cuffed her hands to her same-side ankles, and tied a collar around her neck over the hood, so that she can’t take the hood off by herself. There were three rounds of rest, and the set time increased from 2 minutes to 3.5 minutes. However, Xiaoyu obviously wanted to take a longer rest, and she persisted for 4 minutes and 15 seconds in the last round and made quite some noise at the end. Then there are two sets of sit-ups, each to complete 20 sit-ups and a rest of more than 1.5 minutes without removing the hood. Finally came the most exciting escape challenge of this video. Xiaoyu was box-tied with her hands behind her back and wearing the breathplay hood with no hole. A collar was put around her neck and locked. The key was thrown to a corner of the room. Xiaoyu must first sit in a chair for one minute, then break her hands free, find the key on the floor, unlock the collar, remove the collar, and finally take off the hood. Let’s review the challenge process through the following post-event interview. ―I: You were calm in the first minute. ―Xiaoyu: I had to save the air. It was not difficult to break my hands free. You didn’t make it too tight. ―I: Right, because the game can’t continue if I made it too tight... Then you found the key easily after crawling half of the room. ―Xiaoyu: But it took me a lot of energy to crawl and search for the key. I felt a shortness of breath already. ―I: Then you tried to unlock the lock on the collar, but you found that because your upper arms were tied, you can’t reach the lock by hands, and started panicking and screaming aloud! ―Xiaoyu: There was not much air left, and I had to loosen the rope on my upper arms. I went mad. You see, I still have bruises on my arms from the struggling. ―I: When I heard your scream I thought I had to help, but found that even I couldn’t take the hood off before removing the collar. Luckily, at the same time you calmed down quickly, restored your breathing rhythm and started to work on the lock. ―Xiaoyu: It seems so... ―I: But you couldn’t put the key into the keyhole after trying for a long time, so I decided to help you to unlock. ―Xiaoyu: Huh? Did you? Did you open the lock? ―I: Well, when the lock was removed, you started to lift the edge of the hood, but since the collar was still on your neck, you failed. ―Xiaoyu: Huh? I don’t remember that... ―I: So I had to help you again by taking off the collar. ―Xiaoyu: Did you?... I still don’t remember... Then did I remove the hood and finish the challenge? ―I: No... You just put your hands on the ground and continued to pant for breath with the hood still on, and your body started to shake. ―Xiaoyu: Huh? That sounds so stupid… ―I: So I had no choice but to save you. I took off the hood and watched you panting and shaking on the ground... ―Xiaoyu: So I actually failed the challenge, right? ―I: Don’t you think that you succeeded by yourself? ―Xiaoyu: ... That... I don't know... ―I: So from the time you worked on the lock, what do you remember? ―Xiaoyu: Let me see... I felt like my lifeblood pressure rose and it rushed to my brain. I had a dark red vision. It was so hot and stuffy. I don’t remember more. ―I: ... Alright. Then let me announce officially that you failed and will be severely punished in the next time! Xiaoyu-senpai is really strong and cute, isn’t she?
