We tend to think that crying is a sign of sadness, but in fact crying is a very complex human reaction... 。 Lee Duffne, a dental professor at the University of Miami's Bascompalmer School of Eye Medicine, said: "Crying can be triggered by a variety of emotions such as pain, sadness and, in some cases, extreme joy. It's just a way for us to evolve. ”

It's a good thing that emotions can burst out, because whether it's laughter or crying, it counteracts the effects of cortisol and adrenaline and relieves stress. So if you find yourself crying with joy, there's no need to make a fuss.

And our group of six is now crying with joy. According to Yiyi's route, it is inevitable that you must cross the wall that is more than three meters high.

That's why Yiyi needs six people. Because she needs enough people to build a human ladder. Assuming that the average height of each person is 1.7 meters, and the 'legs' are about 1 meter long, if you want to build a height of 3 meters, you need a total of 3 people. After all, only the height of the first person is complete, and the rest can only sit on the shoulders of the person below, and the usable height is only 70 centimeters. Except for the three people who built the human ladder, the remaining three people can pull the human ladder up after climbing the wall.

The degree of this person's ladder has been carefully considered and calculated, and even I have to admit that she is smart.

Some people may wonder that if it is only a three-meter wall, maybe not six people, but four people are enough. There are three ladders, and the remaining one can pull people up the wall. But this is far from the case. The most important thing is to be dependent. After all, she is a 'girl' child, and she doesn't have the strength to be a human ladder, let alone pull the rest up. If it is only four or five, the one who has built the ladder at the bottom must be discarded under the wall.

Realization, those who participate in this action are desperate to live, who would want to be abandoned? This is not a simple matter of permutations. In fact, if you have a rope, everything is easy to solve. Ke Yiyi and others 'wandered' in the school for half a year, but they couldn't find a strong enough rope.

The mass grave is more than 500 meters away from the wall, and there are many school rules along the way, Yiyi and others are very well prepared, and all of them have been successfully cracked.

When we came to the towering wall, it was exactly twelve o'clock.

"Quick, act as planned." As instructed. After experiencing the mass grave incident, she softened my attitude towards me a lot, and she also told her plan openly and honestly on the way. Free txt eBook In her action, crossing the fence is the final and most critical step of the plan. After listening to it, I put forward some of my own opinions appropriately, and she listened humbly, and thought it seemed to be better, so she adopted it.

The height of the fence and the surroundings were entirely based on the visual measurements of her free time for half a year, and God knows how many variables. The reason why I chose this one is also out of the consideration of being far away from the school 'gate'. There are people on duty 24 hours a day at the school 'gate', and the school police take turns walking around the fence every once in a while.

And half past twelve, it happens to be the shift change, the previous half an hour is the most careless time period for the school police, twelve o'clock school police A will come out of the office, began to walk around the wall, because of the 'handover'***, he will walk very fast. After more than ten minutes, we passed the section of fence that we had to climb over, and returned to the office in more than ten minutes to 'hand' over. Then don't go around in circles alone.

So for us, this place has the most time to escape, and we have half an hour to escape.

After coming to the bottom of the wall, soon everyone was in place and began to build a human ladder as fast as possible. Xu Lu is the strongest, and his height is also the highest, so he is naturally at the bottom of the human ladder. followed by Zhang Guofeng and Li Kang.

Song Mao, who loves to be crooked, was the first to climb up, and I dragged Yiyi's slender waist with my hand and sent her hard, and firmly supported her on Xu Lu's shoulder. The body of a 'girl' child is really not suitable for physical exercise, especially if she can only read and does not like sports. Yiyi struggled to climb up more than a meter with his own strength, and then pulled Song Mao's hand. The guy pulled her against the wall with a single force.

After that, I climbed up smoothly.

And then it's time to pull people.

The three of us pulled Li Kang up first, and Xu Lu, who was used as a human ladder, played a big role at this time, and he lifted Zhang Guofeng in the middle and sent him upward, so that we could hold his hand tightly.

Finally to the most critical place. Zhang Guofeng's whole person was used as an extended rope, and the four people standing at the head of the wall grabbed his hands and pulled them hard. And Xu Lu jumped up slightly, grabbed his 'legs', and climbed up along his body with difficulty.

I don't know how long it took, but when all of us felt our hands become numb, Xu Lu finally climbed up.

'Huh' breathed a sigh of relief, and only Zhang Guofeng was left.

Suddenly, at this moment, a mutation suddenly occurred. The arms that had been carrying a person, which seemed relatively light, suddenly became heavy again, and the sudden weight almost pulled us all down.

"What's going on?" I called down softly, only to hear the sound of Zhang Guofeng kicking his legs hard and scolding in a low voice.

After a few seconds, a message came from below: "'Milk' 'Milk', which 'bastard' grabbed my 'leg'?" ”

"It's me!" A deep male voice rang out: "If you don't want me to fall with him, pull me up." ”

Yiyi, who was standing next to me, trembled and said in surprise: "It's Yuan Liu!" ”

I glanced at her with a smile: "You childhood sweetheart is really like a random sticker, sticking around you wherever you go." ”

Yiyi gritted her teeth angrily: "I guess I saw us sneaking behind after getting up 'bed', this guy, I really couldn't see that he still has such deep endurance and scheming before." ”

"It is said that childhood sweethearts are the pair who know each other the best, but I don't think so, just because they are too familiar, but they are unfamiliar." I shrugged my shoulders: "What do you think about this matter?" ”

Without waiting for an answer, Zhang Guofeng had already scolded angrily: "Boss, let go." Put me down, Lao Tzu wants to fight him alone. ”

Yuan Liu snorted coldly: "Even if you are willing, I'm afraid some people are not willing." ”

I glanced at Yiyi again: "I took back the last sentence, it seems that some childhood sweethearts still understand each other unilaterally." "You've only known me for a day, so you can really understand me?" Yiyi glared at me and instructed the surroundings: "Pull them up, if you don't patrol quickly, you'll find out here!" "The weight of two people is as heavy as lead, and although there is no comparable 'sex' between the two, the fatigue of the hands is very unpleasant.
