Escape From the Library

After the announcement of the convention on Monday night, Yue Xingwen and Jiang Pingce received many private messages from their classmates, especially Yue Xingwen who posted, and the number of unread private messages exceeded a thousand in an instant.Most of them are words of support and thanks, such as "Thank you for your willingness to come forward", "It's really great to have this convention", "I hope that the future library will be as kind as the school" and so on.

Yue Xingwen didn't have time to reply one by one.

He scanned the information at a glance, and found that there were several private messages reporting malicious injuries, all of which happened in the public elective class this week, and were aimed at the two students who threw acid and hurt people with light balls.

Jiang Pingce has also received a lot of private letters, questioning some of the terms of the agreement. Some students are worried that once these students who maliciously hurt people are on the blacklist of the whole school and kicked out of the research group, will they form a "bad group" under extreme circumstances? power"?

Yue Xingwen thought for a while, and said: "This possibility is indeed possible. But senior Zhuo Feng said before that the later courses will become more and more difficult, and you need to be matched with students from various majors to pass the level. Only the building on the third floor The failure rate of the college is astonishingly high. It is quite difficult to gather a multi-disciplinary professional evil force team including language, mathematics, physics, chemistry, politics, history and geography, right?"

Jiang Pingce agreed: "Well, so they can't make a fortune."

Assuming that the chemistry students who poured sulfuric acid and the physics students who blinded others with light balls formed a team, but without Chinese and history liberal arts majors, they would still be unable to pass the next class.It is too difficult to form a gangster team that includes all majors.

Under the restrictions of the convention, 99% of the students will be afraid of the blacklist and abide by the rules, and the rest will become street rats that everyone shouts and beat. Over time, the students who dare to break the rules and be "isolated" by the whole school will become more and more. less.As for individual psychopaths, as long as they don't make a difference, they won't affect most of the students.

At this moment, Qin Lang suddenly sent him a message: "Xingwen, the student from the Department of Physics who flashed people with a light ball sent me a private letter to admit my mistake, and even confessed to the teammate who threw sulfuric acid from the Department of Chemistry. He voluntarily quit the research group and hoped that we Don't publish his name, give him a chance to reform himself, he is willing to apologize to those injured classmates and compensate all the points."

The injuries suffered during the exam will not be brought back to the library. The library is like the resurrection point in the game. The eliminated students are resurrected here in their original state, including the four disfigured girls. Their appearance has also been restored.

If this student used the light ball just on impulse, made a mistake, and is willing to apologize and compensate, and if the injured student is willing to forgive, Yue Xingwen does not want this student to die in the library club completely—the person who lost his way and found his way back, there is still salvation .

Yue Xingwen replied: "Ask the injured classmates for their opinions, after all, they are the victims."

Qin Lang said: "I'm in contact, let them meet in private later, apologize and admit their mistakes in person, and write a guarantee letter."

Yue Xingwen asked, "Where's the guy from the Chemistry Department?"

Qin Lang said helplessly: "Nanyang Jiaotong University's name is Qu Yong, and he doesn't mean to apologize."

That night, under the witness of the supervisory team, the student who hurt someone with the light ball in the Department of Physics and several students who were affected by blindness met privately in the meeting room of the research team on the second floor, apologized and reconciled, and wrote a guarantee that they would not do it again.

The disfigured four girls found Senior Sister Xiao, who majored in psychology, and the senior sister gave them psychological counseling. The four finally cheered up and decided to form a team to continue the following courses.

A few people from Yue Xingwen found the dormitory of Qu Yong, who poured sulfuric acid from the Department of Chemistry, but his roommate said that he had changed dormitories.

——Changing the dormitory at this time is obviously avoiding and refusing to communicate.

Qin Lang sent him a long private message with points, hoping that he could chat with the students in the supervision team, admit his mistake, and make some compensation to the four girls.As a result, he ignored the private messages he received.Qin Lang said with a sullen face: "It seems that he wants to escape to the end. There are more than 9000 dormitories in this library, and it is difficult for us to find one by one."

Jiang Pingce said in a cold voice, "Then let's make an example and publish his information."

Yue Xingwen agrees: "Normal students can't do things like throwing acid at people. What's more, after the release of the convention, we have clearly explained the punishment measures. If he hasn't come forward to apologize or repent, this person obviously has psychological problems, and even Do you think you are right? There is no need to save him."

Everyone discussed for a while, and finally made Qu Yong the first person to be blacklisted in the library.

The turmoil came to an end for the time being. When Yue Xingwen and Jiang Pingce returned to the dormitory after dealing with these matters, they stepped on the 11:[-] p.m. access control time. The entire dormitory building was turned off and the power was cut off. Both of them fell asleep in a hurry before they had time to take a shower.

According to Senior Sister Xiao, the four girls have now adjusted their mentality, and the stone in Yue Xingwen's heart finally fell to the ground. This time, he slept very peacefully and didn't have any nightmares.

In a trance, a familiar deep voice rang in his ears: "Xing Wen, it's time to get up."

A slender hand seems to gently help him straighten his hair, very gentle.Yue Xingwen struggled to open his eyes. Because he just woke up, his eyes couldn't focus for a while, and his voice was a little confused: "What time is it?"

Jiang Pingce curled his lips, withdrew his hand and said, "Before seven o'clock, get up and take a shower, or you won't be able to catch up with today's class."

Yue Xingwen got up yawning and found that Jiang Pingce had just taken a shower and his hair was still wet.

The two of them came back too late last night. As soon as they entered the dormitory, the lights and power were turned off in the whole dormitory area, and they didn't have time to take a shower.Yue Xingwen's body was covered with a layer of sweat, and he was really uncomfortable.He went to the bathroom to take a shower, and then came out refreshed, dried his hair, and put on clean clothes: "Going to the math school today?"

Jiang Pingce nodded: "Well, because of the "Student Convention", I was busy all day yesterday, and everyone suspended classes. I can't skip classes anymore, and I'm going to the mathematics school."

The university alliance is progressing smoothly. The representatives of the 30 school alliances tacitly suspended classes all day yesterday to help Yue Xingwen and the others collect opinions on the forum.Now, the matter has finally settled, and they have to continue to brush their lessons.After all, their most important goal is to graduate from the library as soon as possible. Every time they spend a day here, they don't know what will happen in reality.

Yue Xingwen sent a message on the research group channel: "Everyone, I will meet you at the entrance of the cafeteria. After eating, go to class!"

The four people in Ke Shaobin's dormitory also got up together, and went to the entrance of Xueyi after washing.

Yue Xingwen handed over the 420 points obtained from the public elective course "Orienteering" to Jiang Pingce, and said: "This is the shared points of the research group obtained from the public elective course. You can take care of it. The future team expenses will come from this fund." deduction."

Yue Xingwen spends a lot of money and always likes to buy snacks. Jiang Pingce's life style is more rigorous, which makes Jiang Pingce feel more at ease in managing funds.Jiang Pingce didn't refuse. He took the points and said, "I'll collect the points for meals in the future. You don't have to go alone. After the points are used up, I will ask you to collect the group fee."

Liu Zhaoqing smiled and said, "This is the best, otherwise it would be very troublesome for so many of us to line up to earn points."

Zhuo Feng coughed lightly: "Our public elective courses earn relatively few points, only 120, should we also give it to Ping Ce?"

Yue Xingwen said: "Well, adding up to 540 points is enough for our living expenses for three days. Everyone hurry up to take the exam and get some more points. Don't worry about eating."

At this moment, a cold voice suddenly sounded from behind: "Ke Shaobin?"

Ke Shaobin turned his head in doubt, and met Xin Yan's dark eyes.

Xin Yan wore a blue shirt and black slim-fit trousers today. He was tall and thin, with a paler face.When Ke Shaobin saw him, he immediately walked over with a smile, with an apologetic expression on his face: "I'm sorry, I've been too busy these two days, and I almost forgot to ask you to meet everyone. It's a coincidence this time, senior brother Zhuo Feng and the others are here... "

Xin Yan said: "It doesn't matter." He raised his head, his eyes swept over the three of Zhuo Feng, and said, "This is the team you said, failed the course on the third floor, and went back to rebuild?"

Zhuo Feng helped his forehead helplessly: "This classmate is really straightforward."

Lin Manluo smiled lightly and said, "What he said is also true. We did fail the course on the third floor, and we need to go back and repair it."

Ke Shaobin's face was a little embarrassed: "Xin Yan speaks like this, heck, brothers, don't mind..."

Yue Xingwen stepped forward and asked, "How is your research team?"

Xin Yan said: "It takes 1000 points to set up a research group, and we only get 200 points for public elective courses. It's not worthwhile to disband directly. There are girls in the team who are anesthesiologists and prophylaxis. I decided to take them to take two elective courses in medical school and then take them." Disband."

Yue Xingwen leaned into Zhuo Feng's ear and asked, "Brother, would you mind adding a teammate from the chemistry department? It can cooperate with my heavy rain and pour out highly corrosive acid rain."

Zhuo Feng asked: "Is this Xin Yan?"

"Well, he is Ke Shao's high school classmate, and he has learned the two skills of corrosive aqua regia and infinite alcohol lamp."

"Since you think you can add him, I have no objection."

Yue Xingwen nodded, looked at Xin Yan and said, "Xin Yan, you are not on the same level as our courses, so you can't form a team directly. Otherwise, after you finish the elective courses of the medical school, Zhuo Feng The senior and we should have reached the third floor, and the research group will be expanded by then. We are just short of people, if you don't have a fixed research group, can you consider joining us?"

I thought Xin Yan would say "let's talk", but he actually agreed: "Okay, see you on the third floor."

Ke Shaobin was a little happy, holding his glasses, and said with a smile on his face: "Great! We have another chemistry teammate. I think Xin Yan's infinite alcohol lamp is very cool!"

Xin Yan nodded to Yue Xingwen and the others, then turned to go to the cafeteria for dinner.When passing by Yue Xingwen, he suddenly said lightly: "You have handled the matter of the convention well."

Perhaps this is also the reason why he agreed to join this team. Yue Xingwen smiled and said to his back: "I wish you a smooth pass. See you on the third floor."

Looking at the boy's thin back, Zhuo Feng always felt that Xin Yan had a gloomy temperament. With his cold white complexion, he looked like a vampire who hadn't been exposed to the sun for a long time. He also spoke coldly, which seemed difficult to get along with.However, as a "long-distance magic output", the Department of Chemistry still needs to have one in the team. It can also help in the School of Chemistry later on. Zhuo Feng has no objection to adding him.

Lin Manluo was a little worried: "I'm the only girl, and there are still very few liberal arts majors."

Yue Xingwen comforted her with a smile: "Sister, don't worry, the College of Liberal Arts should be on the back floor. After passing the third floor, we will mainly look for teammates of Liberal Arts, and find a few more girls to accompany you."

Lin Manluo smiled and said, "Okay! Let's finish the previous lessons first."

After a simple breakfast, the seven formed teams at the elevator entrance.

The three of Zhuo Feng went to the medical school on the first floor to re-study, and the four of Yue Xingwen went to the math school on the second floor.

The moment the elevator stopped on the second floor, a cold mechanical voice sounded in my ears: "Welcome to the School of Mathematical Sciences."

As the elevator door opened, Yue Xingwen was so shocked by the scene in front of him that he couldn't speak——

On both sides of the wide corridor are high-tech LCD screens that cover the entire wall. On the screen, lines of formulas are constantly beating. The dense and messy mathematical formulas make liberal arts students feel awe.

In addition to the formulas written on the wall screen, the marble floor under the feet is also regularly arranged with natural numbers from 0 to 9.

It's like a world made entirely of numbers.

In the center of the hall is a screen with [Course Schedule of the School of Mathematics] written on it. The four of them came to the front of the screen and looked up at the schedule——

Liu Zhaoqing couldn't help complaining: "People who are not good at math will kneel when they see the schedule!"

Yue Xingwen gently rubbed his temples: "I was good at mathematics in high school, but I enrolled in liberal arts in college, and I haven't touched mathematics for two years. I almost returned all the knowledge I learned before to the teacher."

Under the big screen in front, some girls were crying softly: "I can't even read the class schedule!"

Another human said: "Is there anyone who is good at mathematics to guide me? As long as you can pass the test, I will give you all the points!"

There was a mess at the bottom of the class schedule screen.

Ke Shaobin whispered: "We can ignore the elective courses for the time being, and only look at the compulsory courses. We missed the class on Monday yesterday, and today on Tuesday, there is only one compulsory course, "Prime Number Labyrinth."

Prime number maze?The three of them looked back at Jiang Pingce at the same time.

Jiang Pingce looked calm: "It should be a large three-dimensional maze related to prime numbers. It needs to use prime number reasoning and some knowledge of three-dimensional geometry. It will not be too difficult."

Three people: "..."

You said it wouldn't be too difficult, it would be a nightmare for others, right?

Yue Xingwen patted the other party's shoulder lightly: "It's up to you."

The four of them walked to the tablet computers placed side by side, and pressed the button of "select courses".

A prompt pops up on the screen——

[Compulsory course for School of Mathematics: Prime Number Maze]

【Credits: 3】

[Examination room rules: subject group limited courses, must register in the form of subject group]

[Course description: This is a three-dimensional maze composed of prime numbers.A prime number, also known as a prime number, refers to a natural number greater than 1 that has no other factors except 1 and itself, and can only be divisible by 1 and itself.

The twin prime number conjecture was proposed by Hilbert in the report of the International Congress of Mathematicians in 1900-there are infinitely many prime numbers p such that p+2 is also a prime number.

Twin prime numbers are pairs of prime numbers with a difference of 2, such as 3 and 5, 17 and 19, all are twin prime numbers]

[Exam requirements: get out of the maze within 4 hours]

[Additional question: Find all twin prime numbers, score +20]

[Remarks: At least one science major with strong computational ability is recommended in the research group]

[Confirm Course Selection: Yes/No]

Yue Xingwen looked at Jiang Pingce: "I confirmed it?"

Jiang Pingce nodded: "Yes."

Yue Xingwen put his hand on Jiang Pingce's shoulder, and joked: "I have to follow you closely, you take me away later, if I get lost in the math maze, I can't get out."

The corners of Jiang Pingce's lips raised slightly: "Don't worry, I won't lose you."

A mechanical voice sounded in the ears of the four——

[C-183 subject group has successfully selected courses, and the exam will start on time at 8:[-], please be prepared. 】
