Escape the Library

【Lucid waters and lush mountains-04】

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

Although it was dark, time was still passing. If they all fell asleep, it would be 8 hours, which is equivalent to 8 days, and no one could tell what would happen outside. Therefore, Yue Xingwen decided to keep vigils in groups.

He glanced at his teammates and quickly arranged: "Me, Pingce, Ke Shaobin, Xin Yan, Qin Lu, Qin Miao, start to sleep at 10 pm, sleep for 5 hours, and get up at 3 am to take over. The remaining 6 people , vigil in the first half of the night, sleep from 3 am to 8 am the next day. Those 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, the second group will work hard, 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 up.

The 6 people in the second group are nominally "night vigils", but there is no need for everyone to blow the cold wind outside. Every once in a while, send two people 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 first group of students had fallen asleep. Lin Manluo, Zhuo Feng, Liu Zhaoqing, Xu Yishen, Lan Yarong, and Zhang Xiaonian sat by the fire to bake, worried about waking up the other students, so they simply used the research group channel to type while chatting.

Zhuo Feng asked, "Manluo, is your third-phase project reliable? Think about it carefully, are there any omissions?"

Lin Manluo typed: "I don't have any actual combat experience. I designed it based on theoretical knowledge. I can only take a step by step. Fortunately, we still have time. Even if the first experiment fails, there is still a chance to save it."

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

Xu Yishen put one hand on the fire to bake, and the other hand typed quickly and said, "A 3-credit course is not difficult in theory. The embryonic development and baby course of the School of Biological Sciences requires 4 credits. I think 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 so-called fooling 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, "No problem was found. The wind was a bit strong outside, the asphalt had solidified, the quicksand was fixed, and the dust was much smaller than during the day."

Lin Manluo was relieved and asked, "Where is the trench dug by Xiao Nian?"

Zhang Xiaonian said: "No problem, we can make a windbreak wall after dawn tomorrow."

The crowd patrolled in small teams and lasted until three in the morning. Xiaotu's loud alarm clock sounded at the base: "It's 3:00 in the morning, the master is about to get up!" Wake up and come 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 sunny, and the asphalt on the ground had completely solidified, forming a protective shell. Everyone hurry up to build the fence and start the construction of the second defense project.

The one-kilometer-long fence needs to be spliced ​​together, with barbed wire and fixed wooden stakes in the middle. The pit dug by Zhang Xiaonian was too large, and everyone planted the prepared fence wall into the pit, and transported some soil from a distance to bury it.

After working all day, the fence is finally finished.

The fence and barbed wire were woven by the students themselves. Everyone was unprofessional, and the twists and turns that were woven were not very good-looking, but overall, the one-kilometer-long protective wall was quite impressive.

Looking at the second phase of the project, Lin Manluo smiled with satisfaction and said, "Sand fixing and sand blocking have been completed. 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 make up for sleep and rest.

That night, the 12 people were divided into two groups to keep vigil again. Since the weather was calm last night, everyone felt more relaxed tonight. After all, it was a 3-credit course, and the library would not deliberately make any moths to embarrass them.

At 2 in the morning, Yue Xingwen's upper and lower eyelids were fighting. The muscles all over the body are sore, and I feel like I can fall asleep just 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 resisted the sleepiness and shook his head: "It's okay, just hold on for another hour."

He took a deep breath and said, "It's too boring to stay in the basement, why don't you go out and have a look."

Jiang Pingce got up and followed him.

The two came out of the house, and when the night wind blew, Yue Xingwen sneezed reflexively. 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 up to the sky and said, "It's really rare to see the moon. The sky in class is always 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 in the moonlight. At this time, the black shadow was shaking with claws on the ground.

Jiang Pingce watched for a moment, then suddenly said, "Is the wind too strong? The fence has been shaking."

Yue Xingwen also found the problem: "We used very thick wooden stakes to reinforce it today, and it is reasonable to say that it will not shake so much." He looked up at the sky, and 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 the face like a knife, the smell of dust in the air, and the feeling of being rubbed by the gravel on the face, all clearly reminded them that the sudden sandstorm at night, their project is likely to be destroyed!

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

Ke Shaobin asked Xiaotu to call someone, and the 6 people who were in charge of the vigil 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 in like a flood, and piled up nearly a meter high on the other side of the fence. The fence was crumbling. It was almost the moment when the six of Lin Manluo were woken up and ran up quickly, "Boom" With a loud noise, the fence wall snapped, and a large amount of sand and dust rushed towards them like beasts out of their cages!

Zhuo Feng shouted: "Fuck, run!"

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

Zhang Xiaonian hurriedly covered the entrance of the underground base with wooden boards, Qin Lu directly moved the plate, and teleported to the distance with his teammates. Everyone looked back and saw that the billowing sand had completely buried their protection projects. For the first two days, they were working in vain!

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 been about martial arts, we have been busy with the project for two days, and it only takes 2 minutes to destroy it! Damn it."

Ke Shaobin said frustratedly, "What should I do now? Are these quicksands going to be cleaned again?" That day, he accompanied Zhang Xiaonian to clean up the quicksand, and his body was covered in ashes. Now that he does it again, Ke Shaobin wants to vomit blood.

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

Jiang Pingce said calmly: "This plan is not right."

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: "Pingce is right, the protection project was destroyed so quickly because our project had loopholes and was not perfect. It's not that the library deliberately destroyed it to make things difficult for us."

Everyone thought about it carefully, and suddenly felt that what Pingce and Xingwen said made sense.

If their engineering is very perfect, it is equivalent to the successful implementation of the windbreak and sand fixation project, and no matter how large a sandstorm is, it will not be easily destroyed. Since it is so easy to be destroyed, we should find problems from ourselves.

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

Zhuo Feng nodded: "Yes, early detection and early resolution. It's better than the end of the exam. It's better that our project has been destroyed. It's only 48 hours later, and we still have more than 300 hours to start over. pass."

Lin Manluo gritted her teeth and said, "It's my fault, I think things are too simple."

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 remember, when I was in law school, I was also under a lot of pressure. Big? This is my first official defense as a lawyer. If I make a mistake, our client will be sentenced to death. But in the end, didn't everyone come over with their teeth?"

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

Yue Xingwen frowned and looked at the dust in the distance, and said, "It seems that this dust storm will last all night tonight, and we won't be able to work. Why don't you all go back to the base to get a good night's sleep and keep your spirits up. Start all over again tomorrow. The first two days, everyone has worked hard, so let’s take it as tuition for this course.”

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

Yue Xingwen looked at Lin Manluo and said warmly, "Senior sister, there are still more than 300 hours. As long as the plan is correct, the time will definitely be enough. Don't think too much, it's not a big deal to fail once or twice."

Lin Manluo nodded: "Well, I have some ideas. Go back and sort it out. Let's talk about it tomorrow."

Qin Lu asked, "Our base was buried by a sandstorm. Can we live tonight?"

Zhang Xiaonian immediately raised his hand: "Before I escaped, I covered the entrance of the base with wooden boards. There shouldn't be a lot of sand in the base. If the plates move down, can you still live?"

Lin Manluo said, "If I turn on the air purifier, it shouldn't be a problem to sleep at the base."

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

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

Except for some sand seeping into the stairs covered by wooden boards, the interior of the base is really clean. Zhang Xiaonian's operation to cover the entrance when he escaped was too timely. Obviously, the younger brother did not 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 has regained her confidence, and she said simply: "I have an idea. Before the official construction, we should do a small sand table project and conduct a rehearsal first."

Ke Shaobin's eyes lit up: "It makes sense! Before large-scale construction, make a small sand table engineering model, artificially create a sandstorm, and see if it can be prevented! Only if the model is prevented and applied 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 in a step-by-step, multi-layered protection, leaving 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 a model and explained to everyone: "If there are gaps like feathers on the wall blocking the quicksand, some of the sand will flow out of the gap and change the direction of flow." She grabbed some The sand removed from the base said: "Assuming that the total amount of quicksand is so much, I only use one row of walls to block it. If the quicksand accumulates heavily, the wall may be crushed. After the wall has a gap, the quicksand will not be in the first row. A wall accumulates, and the sand coming out of the gap will encounter the second wall, and continue to move forward to meet the third layer of interception, until finally, all the quicksand are intercepted by layers."

Zhuo Feng immediately understood: "It's equivalent to breaking the whole into pieces, creating gaps in the walls, reducing pressure, and dispersing and dredging?"

Ke Shaobin said excitedly: "It's like there are many waiting halls in a train station? If you spread out the passengers, you won't overcrowd the station because it's too crowded! This is a good way, and I think it's reliable."

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

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

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

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

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