Escape From the Library

【Green Water and Green Mountains-04】

At night, the basement was still very cold. Liu Zhaoqing skillfully took out the chainsaw and chopped down half of Lin Manluo's tree to use as wood. Xin Yan lit the wood with an alcohol lamp for everyone to keep warm.

Although it was dark, time was still passing.If they all fall asleep, 8 hours is equivalent to 8 days, and no one can tell what will happen outside, so Yue Xingwen decided to keep vigil in groups.

He glanced at his teammates, and quickly arranged: "Me, Ping Ce, Ke Shaobin, Xin Yan, Qin Lu, Qin Miao, go to bed at 10 o'clock in the evening, sleep for 5 hours, and get up at 3 o'clock in the morning to take over. The remaining 6 people , Watch the night in the first half of the night, and sleep from 3 am to 8 am the next morning. People who don’t get enough sleep can take a nap at noon, what do you think?”

Everyone has no opinion.

Jiang Pingce said: "The first group of people should go to bed first, and the second group will work harder. We will change shifts at 3 o'clock."

It was already 9 o'clock in the evening, and everyone went back to their rooms to sleep after washing.

The 6 people in the second group are nominally "night watch", but it is not necessary for all of them to blow the cold wind outside. Every once in a while, send two people up to take a look to ensure that their first phase of the project is not damaged.

Time passed slowly.

In the dead of night, the students in the first group had already fallen asleep.Lin Manluo, Zhuo Feng, Liu Zhaoqing, Xu Yishen, Lan Yarong, and Zhang Xiaonian sat by the fire to enjoy the fire. Worried about waking up other students, the six of them simply used the research group channel to type while chatting.

Zhuo Feng asked: "Man Luo, are your three phases of the project reliable? Think about it carefully, are there any omissions?"

Lin Manluo typed: "I have no actual combat experience, and I designed them based on theoretical knowledge. I can only take one step at a time. Fortunately, we still have time. Even if the first experiment fails, there is still a chance to save it."

Liu Zhaoqing said: "Zhuo Feng, what's the matter with you? Don't be crowed, I think Manluo's plan is very reliable."

Xu Yishen put one hand on the fire and quickly typed with the other hand: "A 3-credit course should not be difficult in theory, and the course of embryonic development and birth of a baby in the School of Biological Sciences requires 4 credits. I feel that this class is also an experience class. As long as we don’t mess around, passing the test will not be a problem.”

Liu Zhaoqing looked back at him: "What do you mean by messing around?"

Xu Yishen said with a smile: "For example, plant a peach blossom forest in the desert."

Everyone: "..."

At this moment, Zhang Xiaonian and Lan Yarong, who were in charge of the inspection, came back.Lan Yarong said: "I didn't find any problems. The wind outside is a bit strong, the asphalt has solidified, the quicksand has been fixed, and the sand and dust are much smaller than during the day."

Lin Manluo felt relieved and asked, "Where is the ditch that Xiaonian dug?"

Zhang Xiaonian said: "It's okay, we can build the windbreak after dawn tomorrow."

They patrolled in small teams until three o'clock in the morning. Xiaotu's loud alarm clock rang at the base: "It's three o'clock in the morning, the master is about to wake up!" Woke up, came to the living room to take over.

The night passed peacefully and nothing major happened.

When we got up in the morning, the weather was rare and clear, and the asphalt on the ground had completely solidified, forming a protective shell. Everyone took the time to complete the fence and start building the second defense project.

The one-kilometer-long fence needs to be spliced ​​up piece by piece, with barbed wire and fixed wooden stakes in the middle.The hole that Zhang Xiaonian dug was too big, so they planted the prepared fence into the hole, and then transported some soil from a distance to bury it.

After working all day, the fence was finally finished.

The fence and barbed wire were woven by the students themselves. None of them were professional, and the crooked weaving was not very attractive, but overall, the one-kilometer-long protective wall was quite decent.

Lin Manluo looked at the second phase of the project and said with a satisfied smile: "Sand fixing and sand blocking have been completed, and the next step is to level the sand dunes and prepare for the third phase of afforestation!"

Everyone was tired all day and took turns to catch up on sleep and rest.

That night, the 12 people were divided into two groups to watch the night again. Because the weather was calm last night, everyone felt more relaxed tonight. After all, it is a 3-credit course, and the library will not intentionally create any moths to embarrass them.

At 2 o'clock in the morning, Yue Xingwen's upper and lower eyelids were fighting.Muscles all over my body are sore, and I feel like I can fall asleep just by lying on the ground.Jiang Pingce glanced at him, and said in a low voice, "Why don't you go to sleep, I'll be watching."

Yue Xingwen shook his head while suppressing his drowsiness: "It's okay, let's hold on for another hour."

He took a deep breath and said, "Staying in the basement is too stuffy, why don't you go out and have a look."

Jiang Pingce got up and followed him.

When the two came outside, Yue Xingwen sneezed reflexively when blown by the night wind.Jiang Pingce turned to look at him, stretched out his slender fingers, and gently helped him zip up his coat: "It's windy at night, don't catch a cold."

Yue Xingwen smiled, wrapped his coat, looked at the sky and said, "It's really rare to be able to see the moon. The sky in class will always be yellow sand, just like the end of the world."

The moon in the desert was big and round, and the cold moonlight sprinkled on the sand. The fence they built cast a large mottled black shadow under the moonlight. At this time, the black shadow was shaking its teeth and claws on the ground.

Jiang Pingce looked at it for a while, then suddenly said, "Is the wind too strong? The fence has been shaking."

Yue Xingwen also discovered the problem: "We reinforced it with very thick wooden piles today, so it should not shake so much." He looked at the sky, his face changed slightly: "The moon is also covered, isn't it dark clouds? "

Jiang Pingce said, "It's a sandstorm!"

The night wind blew on their faces like a knife cut, the smell of dust in the air, and the feeling of grit rubbing on their faces clearly reminded them that if a sandstorm broke out at night, their project might be destroyed!

Yue Xingwen quickly ran back to the base: "Wake up everyone and prepare for protection!"

Ke Shaobin asked Xiaotu to call for someone, and the six people who were in charge of the night watch immediately came to the ground. In just a few minutes, the ground they had previously paved with asphalt was completely buried by a layer of sand!

The sand rushed over fiercely like a flood, and piled up nearly one meter high on the other side of the fence. The fence was crumbling, almost at the moment when Lin Manluo and the others were woken up and ran up quickly, "Boom!" With a loud bang, the fence wall broke, and a large amount of sand and dust rushed towards them like a beast out of a cage!

Zhuo Feng yelled: "Fuck, run!"

If they don't run, they will be buried in the sand.

Zhang Xiaonian hastily covered the entrance of the underground base with wooden boards, Qin Lu moved the board directly, and teleported to the distance with his teammates.Everyone looked back and saw that the billowing dust had completely buried their protective works. In the first two days, they were working for nothing!

Lin Manluo's face was pale and she didn't know what to say.

The others were also very angry, Liu Zhaoqing complained in a low voice: "The library has never talked about martial arts, we have been busy with the project for two days, and it only takes 2 minutes to destroy it! Shit."

Ke Shaobin said dejectedly: "What should we do now? Do we need to clean up the quicksand again?" He accompanied Zhang Xiaonian to clean up the quicksand that day, and his body was covered in ashes. Now that he did it again, Ke Shaobin wanted to vomit blood.

Xu Yi rubbed his temples deeply: "Not only does the quicksand have to be cleaned up, but the asphalt we laid also needs to be cleaned up again?"

Jiang Pingce said calmly: "This plan is wrong."

Everyone turned their heads to look at him. Jiang Pingce said: "Our project was destroyed in an instant, which means that if we continue to follow the original method and have another sandstorm in a few days, the result will still be the same."

Yue Xingwen agreed: "Ping Ce is right. The protection project was destroyed so quickly because our project has loopholes and is not perfect. It is not that the library deliberately destroyed it to embarrass us."

Everyone thought about it carefully, and immediately felt that what Ping Ce and Xing Wen said made sense.

If their engineering is very perfect, it means that the windbreak and sand fixation project has been successfully implemented, and no matter how big the sandstorm is, it will not be easily destroyed.Since it is so easy to be destroyed, you should find the problem from yourself.

Yue Xingwen looked at Lin Manluo and said seriously: "Sister, we don't mean to blame you. No one has experience in this field. You have done a good job. It is normal for the first experiment to fail. Fortunately, this sandstorm It came in time, allowing us to discover the problem in advance, and if it happened later, there would be no time to remedy it.”

Zhuo Feng nodded: "That's right, early detection and early solution. It's better than the end of the exam and our project being destroyed. Only 48 hours have passed, and we still have more than 300 hours to start from scratch." Pass."

Lin Manluo gritted her teeth and said, "It's my fault, I thought things too simply."

Lan Yarong patted her shoulder lightly, and said with a smile: "No one blames you, you have been under a lot of pressure these two days, we all know that. Do you still remember, when I was in law school, I was also under a lot of pressure. Big? It’s the first time I have formally defended in court as a lawyer. If I make a mistake, our client will be sentenced to death. But in the end, didn’t everyone grit their teeth and come over?”

Liu Zhaoqing said: "Yes, you still have so many helpers from us. Don't worry, think carefully about any omissions."

Yue Xingwen frowned and looked at the dust in the sky in the distance, and said: "It seems that the sandstorm will last all night tonight, and we won't be able to work, so why don't you all go back to the base and have a good sleep to recharge your spirits. Start from scratch tomorrow. In the first two days, everyone worked very hard, so let's take it as the tuition fee for this course."

Jiang Pingce said: "Don't think too much, go back and rest."

Yue Xingwen looked at Lin Manluo, and said gently: "Senior sister, there are still more than 300 hours. As long as the plan is right, the time will definitely be enough. Don't think too much, it's no big deal to fail once or twice."

Lin Manluo nodded: "Well, I have a little idea, go back and sort it out. Let's talk about it tomorrow."

Qin Lu asked: "Our base was buried by a sandstorm, can we stay here tonight?"

Zhang Xiaonian immediately raised his hand: "Before I escaped, I covered the entrance of the base with wooden boards. There shouldn't be much sand in the base. If everyone moves down the board, can we still live?"

Lin Manluo said: "I turn on the air purification, sleeping in the base should not be a big problem."

Jiang Pingce said: "Qin Lu, the front is tilted down 45 degrees, 533 meters."

Qin Lu switched positions according to Jiang Pingce's data, and everyone really appeared in the underground base.

Except for some sand seeping in from the stairs covered by wooden planks, the inside of the base is really clean. Zhang Xiaonian covered the entrance when he escaped too timely. Obviously, the younger brother didn’t want to dig the base again, so he subconsciously protected it. of his architectural achievements.

Everyone went back to their rooms to sleep.

The next morning, everyone woke up refreshed and gathered in the living room for a meeting.

Lin Manluo had regained her confidence. She said bluntly, "I have an idea. Before the official construction, we should do a small sand table project and conduct a preview."

Ke Shaobin's eyes lit up: "It makes sense! Before large-scale construction, first make a small sand table engineering model, artificially create sandstorms, and see if it can be prevented! Only when the model is prevented, and it is used in practice, the success rate will be higher. high."

Yue Xingwen asked: "What is the new idea of ​​senior sister?"

Lin Manluo said: "One protective wall is obviously not enough. I want to build several sand barriers step by step, with multiple layers of protection, and leave gaps between the sand barriers to divert the accumulated quicksand. Have you heard of the feather row project?"

Everyone shook their heads.

Lin Manluo took a few leaves as models, and explained to everyone: "There are feather-like gaps left on the walls that block the quicksand, and some sand will flow away from the gaps and change the direction of flow." She grabbed some The sand cleaned up from the base said: "Assuming that the total amount of quicksand is so much, I only need to use a row of walls to block it. If the quicksand accumulates seriously, the wall may be crushed. And after there are gaps in the wall, the quicksand will not The sand that accumulates at one wall and comes out through the gap will meet the second wall, continue to meet the third layer of interception, until finally, all the quicksand is layered and intercepted."

Zhuo Feng immediately understood: "It's equivalent to breaking the whole into parts, creating gaps in the wall, reducing pressure, and spreading out?"

Ke Shaobin said excitedly: "Just like the train station has many waiting halls? If the passengers are spread out, the station will not be overcrowded and the station will not be overcrowded! This method is good, I think it is reliable."

Lin Manluo looked at Xingwen and Heping Ce: "What do you think?"

Jiang Pingce said: "I think it's reasonable. Let's do a model deduction and use Ke Shaobin's laptop. Let's calculate the total amount of quicksand and the load-bearing capacity of the wall to see how many layers of walls are more appropriate."

Yue Xingwen looked at the seriousness of a group of people, and couldn't help feeling: "Our 183 research group is serious, and it looks like a professional scientific research team!"

Although everyone's painting style is usually a bit devilish, once they encounter professional problems, everyone can immediately use the knowledge they have learned to discuss seriously and brainstorm.Lin Manluo's design this time combined knowledge of environmental engineering, mathematical modeling, physical pressure calculation, computer model deduction and so on.

Yue Xingwen believes that there are so many masters in the team, nothing can stop them.
