Escape the Library

After the release of the convention on Monday night, Yue Xingwen and Jiang Pingce received many private messages from their classmates, especially the one posted by Yue Xingwen. Most of them are expressions of support and gratitude, such as "Thank you for your willingness to come forward", "It's really nice to have this convention", "I hope the library in the future will have more goodwill like the school" and so on.

Yue Xingwen didn't have time to reply in turn.

He scanned the information at a glance, and found that there were several private messages reporting malicious and hurtful people, all of which happened in this week's public elective course, and they were aimed at two classmates who splashed sulfuric acid and hurt people with light balls.

Jiang Pingce also received a lot of private messages, questioning some of the terms of the convention. Some students worry that once these malicious and hurtful students are blacklisted by the whole school and kicked out of the research group, will they form a group of "evil" under extreme extremes. power"?

Yue Xingwen thought for a while and said, "This possibility does exist. But senior Zhuo Feng said before that the following courses are getting more and more difficult, and you need to match students from various majors to pass the level, only the building on the 3rd floor. The failure rate of the college is astonishingly high. It is difficult to gather a multi-disciplinary professional evil force team including foreign languages, mathematics, physics, chemistry, politics, history and geography, right?"

Jiang Pingce agreed: "Well, so they can't become a climate."

Suppose the students from the Chemistry Department who splashed sulfuric acid and the students from the Department of Physics who blinded others with a ball of light formed a team, but without their teammates majoring in Chinese and history, they would still not be able to make it through the following classes. It is also too difficult to form a team of evil and evil that covers all majors.

Under the restrictions of the convention, 99% of the classmates 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 number of 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 become a climate, they won't affect most of the classmates.

At this moment, Qin Lang suddenly sent him a message: "Xingwen, a classmate from the Department of Physics who used light **** to flash people sent me a private message to admit that he was wrong, and also confessed to his teammates from the Department of Chemistry who threw people with sulfuric acid. He voluntarily quit the research group and hoped that we Don't publish his name, give him a chance to reform, he is willing to apologize to the 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 a resurrection point in the game. The eliminated students are in their original state after being resurrected here, including the four disfigured girls who have now recovered their appearances.

If this classmate used the ball of light on impulse and made a mistake, he is willing to apologize and compensate, and if the injured classmate is willing to forgive, Yue Xingwen also does not want this classmate to die completely in the library club.

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

Qin Lang said, "I'm in the process of contacting, and I'll ask them to meet in private, apologize in person, and write a letter of guarantee."

Yue Xingwen asked, "Where's the one 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 supervision team, the students who were injured by the light ball and several students who were affected by the blindness met privately in the conference room of the research group on the negative second floor, apologized and reconciled, and wrote a letter of guarantee that they would not do it again.

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

Several people from Yue Xingwen found the dormitory of Qu Yong, who was throwing sulfuric acid in the Department of Chemistry, but the roommate said that he had changed the dormitory.

- At this time, changing dormitories is obviously escaping and refusing to communicate.

Qin Lang spent his points and sent him a long private message, hoping that he could chat with the classmates in the supervision group, admit his mistake, and make some compensation for the four girls. As a result, he ignored the private messages he received. Qin Lang said with a sullen face: "It seems that he is trying to escape to the end. There are more than 9,000 dormitories in this library, and we can't find them one by one."

Jiang Pingce said coldly: "Then let's show an example and publish his information."

Yue Xingwen agreed: "Normal classmates can't do things like throwing acid at people, not to mention that after the release of the convention, we have clearly explained the punishment measures, and he has not come forward to apologize or repent, this person is obviously mentally ill, and even Think you're right? There's no need to save him anymore."

After deliberation for a while, Qu Yong finally became the first person to be blacklisted in the library.

The turmoil came to an end temporarily. When Yue Xingwen and Jiang Pingce returned to the dormitory after dealing with these matters, they stepped on the door at 11:00 pm. The lights in the entire dormitory were turned off and the power went out. The two hurriedly fell asleep before taking a shower.

Listening to Senior Sister Xiao, the four girls' mentality has now been adjusted, and the stone in Yue Xingwen's heart finally fell to the ground. This night, he slept very peacefully and did not have nightmares.

In a trance, a familiar low voice sounded in my ear: "Xingwen, it's time to get up."

A slender hand seemed to gently help him arrange his hair, very gentle. Yue Xingwen struggled to open his eyes, but 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 the corners of his lips and retracted his hand: "Before seven o'clock, get up and take a shower, otherwise 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 door, the entire dormitory area turned off the lights and the power went out, and they didn't have time to take a shower. Yue Xingwen had a layer of sweat sticking to her body, which was really uncomfortable. He went to the bathroom to take a shower, then came out refreshed, dried his hair, and put on clean clothes: "Going to the math school today?"

Jiang Pingce nodded: "Well, I was busy all day yesterday because of the "Student Convention", and everyone suspended classes. I can't skip classes today, and prepare to go to the Mathematics School."

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

Yue Xingwen sent a message on the research group channel: "See you at the entrance of the cafeteria, everyone, go to class after dinner!"

The 4 people in Ke Shaobin's dormitory also got up together and went to the door of the school after washing up.

Yue Xingwen gave Jiang Pingce the 420 points obtained from the public elective course of "Orienteering" and said, "This is the point shared by the research group obtained by the public elective course, you can take care of it. In the future, the team expenditure will be used from this fund. deducted."

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 more at ease in managing funds. Jiang Pingce didn't refuse. He took the points and said, "I'll collect points for meals in the future. You don't need to brush them individually. When the points are spent, I'll ask you to collect the group fee."

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

Zhuo Feng coughed lightly: "We earn relatively few points for public elective courses, only 120, should we also give it to Pingce?"

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

At this moment, a cold and indifferent voice suddenly sounded behind him: "Ke Shaobin?"

Ke Shaobin turned back suspiciously and met Xin Yan's dark eyes.

Xin Yan was wearing a blue shirt and black slim trousers today. He was tall and thin, and his face became paler. When Ke Shaobin saw him, he immediately walked over with a smile, and said apologetically, "I'm sorry, I've been so busy these past two days that I almost forgot to ask you to meet with everyone. It's a coincidence this time, Senior Brother Zhuo Feng and the others are..."

Xin Yan said: "It doesn't matter." He raised his head, his eyes swept over the three of Zhuo Feng lightly, and said, "That's what you said, the team that passed the exam on the third floor and went back to rebuild?"

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

Lin Manluo chuckled and said, "What he said is also true. We did fail on the third floor and we have to go back and rebuild."

Ke Shaobin's face was a little embarrassed: "Xin Yan is like this when he talks, ahem, senior brothers, don't mind..."

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

Xin Yandao: "It takes 1,000 points to set up a research group, and we only get 200 points for our public elective courses. It is not cost-effective to directly disband. There happened to be girls in anesthesia and prevention in the team, so I decided to take them to two elective courses in medical schools. Disband."

Yue Xingwen leaned into Zhuo Feng's ear and asked, "Senior brother, would you mind adding a teammate from the chemistry department? You can cooperate with my torrential rain to produce extremely corrosive acid rain."

Zhuo Feng asked, "Is this Xin Yan?"

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

"Since you think you can add him, I have no problem with it."

Yue Xingwen nodded, looked at Xin Yan and said, "Xin Yan, your course progress with us is not on the same level, so you can't directly form a team. Otherwise, wait until you finish the elective courses of the medical school, Zhuo Feng. The senior and us should be on the 3rd floor, and the research group will be expanded. We are just short of people. If you don't have a fixed research group, can you consider joining us?"

He thought Xin Yan would say "Let's talk about it", but he actually agreed: "Okay, see you on the third floor."

Ke Shaobin was a little happy. He held his glasses and said with a big smile, "Great! We have another teammate from the Department of Chemistry. I think Xin Yan's unlimited alcohol lamp is very cool!"

Xin Yan nodded at Yue Xingwen and the others, then turned to eat in the cafeteria. When passing by Yue Xingwen, he suddenly said lightly, "You handled the contract well."

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

Zhuo Feng looked at the thin back of the boy, and always felt that Xin Yan had a gloomy temperament. His cold white complexion looked like a vampire who hadn't basked in the sun for a long time. However, as a "remote magic output", the Department of Chemistry still had to have one in the team. In the later stage, he could also help in the School of Chemistry, but Zhuo Feng did not object to adding him.

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

Yue Xingwen smiled and comforted her: "Senior sister, don't worry, the Faculty of Arts should be on the back floor. After the third floor, we will mainly find teammates of the Faculty of Arts and 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 people formed a team at the elevator entrance.

The three of Zhuo Feng went to the medical school on the first floor for reconstruction, and the four of Yue Xingwen went to the mathematics college 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 her that she was speechless—

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

In addition to the formulas written on the wall screen, the marble floor at the foot is also arranged in the natural number law of 0~9.

It's like a world made entirely of numbers.

In the center of the hall is a screen that reads [School of Mathematics for this week]. The four of them came to the front of the screen and looked up at the course schedule—

Monday/Wednesday

8:00-10:00, Death Code (required, credit 6)

10:00-12:00, Sequence (Elective, credit 2)

14:30-16:30, Calculus (Elective, credit 3)

14:30-16:30, death code (compulsory, credit 6)

16:30-18:30, Fourier Series (Elective, credit 6)

Liu Zhaoqing couldn't help but complain: "Those who are not good at math will kneel when they see the timetable!"

Yue Xingwen gently rubbed his temples: "I was good at math when I was in high school, but I applied for liberal arts in college. I haven't touched math for two years, and I have given back almost 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!"

There is also a humane: "Are there any mathematicians who can lead me? As long as you can pass the test, all the points will be given to you!"

The bottom of the timetable screen is a mess.

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

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

Jiang Pingce looked calm: "It should be a large-scale three-dimensional maze related to prime numbers. It requires the use of prime number reasoning and some knowledge of three-dimensional geometry, so it won't be too difficult."

Three people: "…"

You can't say it's too difficult, it's a nightmare level for others, right?

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

The four of them walked to the tablet computers placed side by side and pressed the "Course Select" button.

A prompt pops up on the screen—

[Compulsory course in the School of Mathematics: Prime Number Maze]

【Credits: 3】

[Exam room rules: Courses are limited to the subject group and must be registered in the form of a subject group]

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

The twin prime conjecture, proposed by Hilbert at the International Congress of Mathematicians in 1900—there are infinitely many prime numbers p, so that p+2 is also a prime number.

Twin primes are pairs of prime numbers that differ by 2, such as 3 and 5, 17 and 19, which are all twin primes]

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

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

[Note: It is recommended that there be at least one science student with strong computing ability 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 with you later. If I get lost in the math maze, I won't be able to get out."

Jiang Pingce raised his lips slightly: "Don't worry, I won't lose you."

There was a mechanical sound in the ears of the four of them—

[C-183 subject group has successfully selected courses, and the exam will start on time at 8:00, please be prepared. 】
