Time is like water, counting from the moment the elevator fails, and 90 minutes have passed quickly.

During this period, because Pang Xiaobai, Jin Ruoyu and Tang Haixing were all partying frantically below, no one went up to take a look, and naturally no one found that the elevator was out of order, and there were four people trapped in the elevator and couldn't get out.

Even the security guards on duty hid in the rest room of the duty room and brushed small videos, knitting sweaters, none of them went out to patrol, and none of them went to the monitoring room to watch the surveillance screens.

As a result, Hu Qiang and Ouyang Mofei, as well as Su Kejie and Sha Lele, were still trapped in the elevator and could not be saved.

"Ajay-sensei!" Sha Lele, who had looked at the time on his mobile phone again, raised his head and looked at Su Kejie, who was constantly painting stars on the wall, "It's been an hour and a half, why hasn't Teacher Xiaobai come yet?" Why hasn't anyone come to our rescue yet? ”

Su Kejie stopped his hand and said expressionlessly: "What else can it be, it must be these grandsons eating and drinking spicy food below, maybe they even sing and dance, and they are so excited that they forget about us." ”

"Huh?" Sha Lele frowned, "What should I do then?" You won't keep coming to us, will you? ”

"Don't worry." Su Kejie continued to draw stars on the inner wall of the elevator.

"When they are tired and have had enough, and find that I haven't been there, they will naturally think of me, they will naturally call me, and if they can't get through, they will naturally go to me. When the time comes, nature will find that we are trapped, and nature will be able to rescue us. ”

Hearing this, Sha Lele nodded: "Makes sense." ”

After putting down the snacks, Sha Lele turned his head to look at the stars painted on the wall and said, "Teacher Ajie, you are drawing so many stars, are you simulating the starry sky, so as to help you sleep at night?" ”

Su Kejie glanced at Sha Lele slowly and steadily, and then suddenly burst out: "I'm drawing a meteor, and then making a wish, cursing Xiaobai for their documents, every time they are halfway through writing, they crash, and they haven't been saved!" ”

Seeing Su Kejie's appearance, Sha Lele blinked, and then realized that Su Kejie's calm was all pretended, in fact, he was also very angry, very frightened, and worried in his heart, but he kept a paralyzed expression and seemed to be calm.

It turns out that Mr. Applejack is also an ordinary person, Sha Lele thought.

After understanding this, in order to avoid continuing to stimulate Su Kejie, Sha Lele hurriedly wanted to find another topic to divert his attention.

Suddenly, she saw the half can, so her eyes lit up, and she picked it up: "Teacher Ajie, there is still half a can left here, otherwise, let's tear this up, add my hairpin, and make a simple antenna, right?" ”

With that, Sha Lele stood up with half a can and took another hairpin out of his hair.

Su Kejie turned his head to look at Sha Lele, and then at the half of the cans and hairpins in her hand.

Taking the half of the can with one hand and looking at it, Su Kejie shook his head: "The area of this half of the can is too small, even if it is torn to make an antenna, it may not have an effect, and it is likely to be useless." ”

"Then it's good to give it a try." "What if it succeeds?" ”

Su Kejie looked at the half of the can in his hand again, looked around again, shook his head at Sha Lele with an expressionless face and said, "No, we can't take risks, because this half of the can has a more important role." ”

"More important?" Sha Lele wondered, "What is more important?" ”

"Survive!" Su Kejie said with a serious face.

"Survival?" Sha Lele replied with a confused face.

Su Kejie nodded calmly.

Immediately afterwards, Su Kejie looked down at the half of the can, and said indifferently:

"At the moment, it seems that we may be preparing for the worst.

That is, we will most likely spend forty-eight hours, if not more, in this elevator without water, and without food.

For such a long time, you can boil without food, but you can't do without water.

So, we're going to use this half of the can to store water! ”

"I know!" Sha Lele said suddenly, "It's using the temperature difference between day and night to create condensate, right?" ”

Su Kejie shook his head and said: "No, the method of condensate will not work, because to make condensate, you must first have enough water vapor and enough condensation equipment."

But there's nothing here, and you can't make enough condensate at all.

Even if you can barely make a little condensate, it is a drop in the bucket, and it is not enough for survival. ”

"Can't make condensate?" Sha Lele frowned and asked, "What should I do then?" Or rather, what's the use of this half can? ”

Su Kejie looked at the can in his hand again and said, "I mean, we can use this half of the can to fill urine, and then drink urine to replenish water." ”

"Huh? Drinking urine? Sha Lele's mouth opened wide, his face full of shock.

"That's right." Su Kejie said steadily, "Drink urine!" ”

After speaking, Su Kejie explained in a calm tone: "I said, for forty-eight hours, people can't drink water, but there is no water here at all.

So, in extreme cases, we can drink urine to replenish water.

Because 95 percent of the urine is water, and the rest is urea and inorganic salts and things like that.

Although the taste of urine is not good, drinking urine can indeed temporarily replenish water, maintain blood volume in the body, delay the onset of dehydration symptoms, and maintain the relative balance of electrolytes in the body.

In this way, it naturally prolongs our survival time and maximizes the chance of being rescued.

Of course, if you feel psychologically overwhelmed and can't drink your own urine, we can interchange, you drink mine, I drink yours. ”

"No, no, absolutely not!" Sha Lele hurriedly frowned and waved his hand, "I don't drink urine, and I don't drink it even if I die!" ”

Su Kejie saw Sha Lele's resolute refusal to drink urine, and no longer continued the topic, but looked around:

"Speaking of which, it's more inhospitable than a desert, and the only advantage is that it's boxy.

However, I'm not sure if this elevator will continue to behave like a demon, such as suddenly falling down or something.

So, it's okay if we don't drink urine, maybe we would have fallen down the elevator and died before we died of thirst. ”

As soon as he heard this, Sha Lele hurriedly said with a frightened face: "Teacher Ajie, don't say it, I'm even more scared when I hear it!" ”

Speaking of this, Sha Lele suddenly saw that Su Kejie was still calm, so he immediately asked, "So, you pretended to be so calm to comfort me, right?" ”

"No!" Su Kejie said calmly, "I was born with this expression, but in fact, I was panicked. ”

"Huh?" Sha Lele opened his mouth wide.

Su Kejie suddenly turned around and sat down against the wall, and said calmly: "Sit down and rest for a while, this can save some physical strength and increase survival time." ”

As soon as Su Kejie said this, Sha Lele also sat down against the wall, folded his hands, and whispered in his mouth:

"God Buddha, Fusheng Tianzun, no matter what god in the south, east and west, I beg you, let Teacher Xiaobai find us as soon as possible, so that you can come and rescue us as soon as possible!"

I don't want to drink pee, and I don't want to be thrown to death!

I'm still young, I want to live, please! ”
