But this time, we were not as embarrassed as the previous two times, on the contrary, we all had a sense of sympathy for each other and ourselves in our eyes.

Neither of us spoke, just looked into each other's eyes and smiled in unison. I didn't know what the two of us meant by that smile, and I didn't think to figure out what it meant.

I just wanted to laugh, and the timing was right, so I laughed.

I used my eyes to signal Xue Kongqin to turn around, because she was facing my direction, it was very difficult to go out, she should have made a mistake, otherwise why did she squat down and face me in this direction?

Xue Kongqin immediately understood, and slowly straightened up, turned his body, and urged down again, while reaching behind his right hand to cover the large patch of skin exposed in the middle of his skirt and shirt.

But even so, I could still see a lot of the white skin on her back, and not only that, but what was more exaggerated, I saw another thing that showed a little bit, and although it only showed the top edge, I could guess its full appearance.

This is definitely a pink lace-up panties!

Because I really saw the head of the rope peeking out beside it.

Idols are really different!

No wonder it can attract so many otaku uncles, they are so bold and bold, how can it be impossible to attract those dead houses and uncles who are single to the point of disgusting?

I followed Xue Kongqin and slowly moved towards the back door, I didn't pay attention before, I thought I would go out directly, but I didn't expect that I encountered the same obstacle as last time.

I don't know that bastard took another notebook and blocked the crack in the back door.

Xue Kongqin tried to pull it with his hand, of course, it was the book that he pulled, and now he pulled the door, which is tantamount to asking for his own death. The book was clamped tightly, and Xue Kongqin couldn't pull it out at all with some strength.

There was really no way, Xue Kongqin was a little anxious, turned his head and looked at me pitifully, hoping that I could find a way to solve this problem, otherwise, the two of us could only obediently return to our seats, and then wait for the end of class to be overwhelmed by the crowd.

If I hadn't encountered this situation before, I would have been at a loss if I was suddenly asked at this time.

But,I've encountered this kind of situation where the door is caught by the notebook before.,How embarrassing it is to be made.,If I hadn't been witty and hid at that time.,No matter how thick-skinned you are,,It will also be pierced by the teacher's angry gaze.。

Now the murderer who killed me last time was in front of me, and she was now bothered by this kind of blocking the back door. This is really the reincarnation of the way of heaven, which harms others and ultimately harms oneself.

But for the sake of Xue Kongqin being so beautiful and lovely today, I still decided to go up and help, of course, this is not for Xue Kongqin, because I also have to go out, and helping this murderer is really just a matter of incident!

Because I have encountered this situation before, I have thought deeply about this problem since then, and how to solve it if I encounter it again. I used my ingenuity and Baidu to find two small methods.

The main embarrassing situation we are experiencing now is that the gap in the door is blocked by the notebook, and we have to go out and open the door, and the door will make a noise because it is squeezed too tightly and rubbed.

According to this principle,There are two ways,If the door is not too tight,The exposed part of the book can be pinched by hand,Then grab this exposed place,Slowly shake it up and down,Slowly shake the book out of the crack in the door。 As long as the notebook is taken out of the crack in the door, then the problem will be solved.

However, the scope of adaptation of this situation is not wide, because in most cases, everyone folds the book into a very small ball, and then clamps it tightly close to the crack of the door, and there is no part exposed outside for you to scratch.

If this happens, it's crazy, what should I do?

Of course, there is a workaround. Think about the reason why the sound is made, and it is because the connecting part of the door is too tight. If it is too tight, it will lead to an increase in the coefficient of friction, because the coefficient of friction is large, so the friction will have a sound.

Then we just need to reduce the coefficient of friction.

It's very simple, as long as the paper ball inside the door is wet with water, the wetter the better, and of course, the connecting part of the door shaft is also mixed with water, so that their friction coefficient is reduced. When the paper ball gets wet, it will become loose, the coefficient of friction will drop significantly, and there will be no sound when the door is sliding, of course, if there is a problem with the door itself, then this method will not solve it.

Of course, if conditions allow, the two methods are better when used together.

Our current situation is only suitable for the second one, and the paper ball inside barely showed anything, so it came out a little, and it was just pulled off by Xue Kongqin.

I immediately turned around and sneaked back to my table, just as I had bought a bottle of Coke on the way here and didn't finish it, and I had exactly a third of the amount left. I didn't think this was the time when it would come in handy.

I got the Coke and went back to the door, secretly poured the Coke into the crack of the door, and then sprinkled some more on the shaft under the door, and the top one was too high, so I didn't want to.

After waiting for two minutes, I think the paper ball should have absorbed enough water.

It's time to get moving.

Without hesitation, I grabbed the switch inside the door, and pulled it with all my might.

"Shhh Hiss! Hiss ......"

The door turned out to be different from what I expected, and there was a loud, screeching sound.

Why? When I looked at the paper ball on the ground, it turned out to be the kind of book that was a little oily and didn't absorb water!

No, such a luxury! Who is it? Sick?

In an instant, half of the eyes of half of the class were attracted again.

But I couldn't care about it so much, so I immediately turned around and motioned for Xue Kongqin to escape with me.

As soon as I lowered my head, I immediately squeezed out through the crack in the door that happened to be close to my body, and then I turned around and waited for Xue Kongqin.

But when I looked back, I was dumbfounded.

Originally, I was able to cling to the crack in the door that came out, but it was not enough to get to Xue Kongqin, and the other parts were fine, the key was that some extra place protruded and was squeezed flat, but it was still stuck there.

Forehead......

Speechless......

Absolutely......

It's infuriating......

Is there any mistake......

Sure enough, it's redundant......

That's not right.

I reacted instantly, I'm a man now, why do I envy being boobsed by people? Am I a pervert?

I immediately reached out and pushed the door open a little more, pulling Xue Kongqin out.

As soon as I came out, I took Xue Kongqin's hand and ran towards the nearest staircase. I vaguely heard the angry voice of the teacher in the classroom behind me.

There was also an uproar from the students.
