Escape From the LibraryCh38 - Prime Numbers Maze 01

After the Convention was released on Monday night, Yue Xingwen and Jiang Pingce received many private messages from students, especially Yue Xingwen who posted it. His unread private messages broke through thousands. Most of the comments were supportive and thankful, such as “Thank you for your willingness to come forward,”

“It’s great to have this Convention,” CJN i7

“I hope the library in the future can have more kindness like the school,” and so on.

Yue Xingwen did not have time to reply one by one.

Story translated by Chrysanthemum Garden.

He scanned through the messages at a glance and found several private messages reporting malicious assault, all of which happened in the week’s Public Elective course, targeting the same two students who had thrown acid and injured people with a ball of light.

Jiang Pingce also received a lot of private messages, questioning some of the terms of the Convention. Some students worried that once the students who were blacklisted and kicked out of the Research Group, would they re-group to form an ‘evil force’? uAFDzo

Yue Xingwen thought about it and said, “This possibility does exist. However, senior brother Zhuo Feng said before that the later courses are getting harder and harder, and it needs to be paired with various majors to pass. The failure rate of the Faculty of Architecture on the 3rd floor alone is incredibly high. It’s also quite difficult to put together a professional evil force team that includes various majors right?”

Jiang Pingce agreed with him, “En, so they won’t get far.”

Assuming that the chemistry student who poured acid and the physics student who used the ball of light to blind others were grouped together, but there were no teammates in the Chinese, History and other liberal arts majors, they still could not get through the later courses. It was also hard to assemble a team of evil forces that encompassed all majors.

Under the restrictions of the Convention, 99% of the students would be afraid of the blacklist and abide by the rules. The remaining one would become the street rats that everyone shouted and beat. Over time, there would be fewer and fewer students who dared to break the rules and be ‘isolated’ by the whole school. As for individual psychopaths, as long as they did not go far, they would not have an effect on most students.

At this moment, Qin Lang suddenly sent him a message: “Xingwen, the student from the Physics Department who blinded the students with his ball of light sent me a private message to admit his mistake, and also gave up the teammate from the Chemistry Department who splashed the students with acid. He voluntarily withdrew from the Research Group, hoping that we would not publish his name and give him a chance to reform, and he’s willing to apologize to those few injured students and compensate for all the points.”

Injuries suffered during the exam would not be brought back to the library. The library was like a resurrection point in the game, the eliminated students were resurrected here in their original state, including the four disfigured girls who had now recovered their appearance.

If this classmate’s use of the ball of light was only a momentary impulse, a mistake, willing to apologize and compensate, and if the injured student was willing to forgive, Yue Xingwen did not want this classmate to completely die in the library—— the people who could get back on the right path, could still be saved.

Yue Xingwen replied, “Ask the injured students for their opinions. After all, they are the victims.” 2KvDMS

Qin Lang said, “I’m contacting them, and I’ll let them meet privately later to apologize and admit their mistakes in person and write a letter of guarantee.”

Yue Xingwen asked: “What about the one from the Chemistry Department?”

Qin Lang said helplessly: “Nanyang Jiaotong University, his name is Qu Yong, and he has no intention to apologize.”

That night, the Physics Department student who injured the other students with the ball of light and several students affected by the blindness met privately in the Research Group’s meeting room on the -2nd floor in the presence of the Supervision Team. They apologized and reconciled, and wrote a letter of guarantee that they would not do it again. 2N84sz

The four disfigured girls found the psychology major senior, sister Xiao, who gave them counseling, and the four finally regrouped and decided to team up to continue their later courses.

Yue Xingwen and several people found Qu Yong’s dormitory, the chemistry student who threw acid, but his roommate said that he had changed the dormitory.

—— Changing dormitories at this time was obviously escaping and refusing to communicate.

Qin Lang spent the points to send him a long private message, hoping that he would talk to the students in the Supervision Team, admitting his mistake and making some compensation to the four girls. As a result, the private message was ignored. Qin Lang calmly said, “It seems that he is trying to escape to the end. This library has more than 9,000 dormitories, so it’s hard for us to check one by one.” frCpY

Jiang Pingce coldly said, “Then, let’s take him as an example, and publish his information.”

Yue Xingwen agreed, “Normal students can’t do things like throwing acid at people, not to mention, after the Convention was issued. We have clearly explained the punishment measures, but he has not yet come forward to apologize and repent. This person is obviously psychologically ill, and even thinks he’s right? There is no longer any need to save him.”

Chrysanthemum Garden.

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

The matter had come to an end for the time being. Yue Xingwen and Jiang Pingce returned to the dormitory after dealing with these matters when they stepped on 11:00pm access control time at night. The lights in the entire dormitory building went out and the power also went out. Both of them did not have time to shower before they hurried to sleep. XNi25R

Listening to senior sister Xiao say that the four female students had finally adjusted their mindset, the stone in Yue Xingwen’s heart had finally fallen to the ground. He had a peaceful sleep, and none of them had nightmares.

Suddenly, a familiar low voice was heard in his ears, “Xingwen, it’s time to get up.”

We’re sorry for MTLers or people who like using reading mode, but our translations keep getting stolen by aggregators so we’re going to bring back the copy protection. If you need to MTL please retype the gibberish parts.

A slender hand seemed to help him tidy up his hair, gently. Yue Xingwen struggled to open his eyes. Having just woken up, his eyes were out of focus for a moment, and his voice was a little confused, “What time is it ah?”

They came back late last night, and the lights went out as they just entered the dorm door. The power went out in the entire dormitory area, so they did not have time to shower. Yue Xingwen had a layer of sweat on his body, and it was really uncomfortable. He went to the bathroom and took a shower, and then he walked out refreshed, dried his hair, and changed into clean clothes, “Going to the Faculty of Mathematics’ course today?”

Jiang Pingce nodded, “En. Yesterday, we were busy all day because of the <Student Convention>, and everyone suspended their courses. We can’t skip class again today, so get ready to go to the Faculty of Mathematics.”

The University Alliance was progressing smoothly. Yesterday, the representatives of the 30 University Alliances tacitly suspended classes and helped Yue Xingwen to collect opinions from the forum. Now that the matter had finally settled, they had to move on to pass their courses. After all, their most important goal was to graduate from the library as soon as possible, and for every day they delayed here, there was no telling what would happen in reality. tJQAbC

Yue Xingwen sent a message on the Research Group’s chat channel: “See you all at the entrance of the canteen no.1. Let’s go to class after eating!”

The four people in Ke Shaobin’s dormitory also got up together. After washing up, they went to the entrance of canteen no. 1.

Yue Xingwen handed off the 420 points he got from the Public Elective course of <Cross-Country Orienteering> to Jiang Pingce, and said, “This is the shared points of the Research Group that we got from the Public Elective course. You can manage it. Future team expenses will be deducted from this.”

Yue Xingwen was a big spender, and he always liked to buy snacks. Jiang Pingce’s lifestyle was more rigorous, so he was assured if Jiang Pingce managed the funds. Jiang Pingce also did not refuse, taking the points and saying, “I’ll unify the points for future meals, so you don’t have to pay individually. When this point is spent, we’ll find you guys to collect the group fee.” l4vT2r

Liu Zhaoqing smiled, “This will be the best, otherwise it’s quite troublesome for so many of us to line up to swipe points.”

Zhuo Feng coughed lightly, “We earn less points for our Public Elective course, only 120. Do we need to give it to Pingce too?”

Yue Xingwen said, “En, it adds up to 540 points, enough to cover our living expenses for three days. Let’s hurry up to pass the exams, get some more points, and we don’t have to worry about eating.”

At this moment, a cold and indifferent voice suddenly sounded behind them, “Ke Shaobin?” oSziOW

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

Xin Yan wore a blue shirt today, with black slim trousers. He was tall and slender, and his face looked paler. After seeing him, Ke Shaobin walked over with a smile, with an apologetic face, “I’m sorry ah, I’ve been so busy these past two days that I almost forgot to ask you to meet with everyone, but this time it’s a coincidence that senior brother Zhuo Feng and the others are all at…”

Xin Yan said, “It doesn’t matter.” He raised his head, and glanced at Zhuo Feng and his teammates, “This is the team you said, the one that failed on the 3rd floor and went back to retake the course?”

Zhuo Feng held his forehead helplessly, “This student is really straightforward ah.” u9EPf8

Lin Manluo laughed lightly and said, “What he said is also the truth, we did fail a subject on the 3rd floor and had to go back to retake it.”

Ke Shaobin was a little bit embarrassed, “Xin Yan is like this when he speaks. *Cough*, senior brother, if you don’t mind…”

Yue Xingwen stepped forward and asked, “What happened to your Research Group?”

Xin Yan said, “It takes 1,000 points to set up a Research Group, and we only got 200 points for our Public Elective course, so it’s not cost-effective to just disband. There happen to be female students from anesthesia and prevention medicine on the team, so I decided to brush up on two Faculty of Medicine’s electives before disbanding.” UKZq1t

Yue Xingwen leaned over to Zhuo Feng’s ear and asked, “Senior brother, do you mind adding a teammate from the Chemistry Department? He can cooperate with my torrential rain and produce a very corrosive acid rain.”

Zhuo Feng asked, “Is this Xin Yan?”

“En, he is Ke Shaobin’s high school classmate. He’s currently learning the skills of Corrosive Aqua Regia and Infinite Spirit Lamp.”

“Since you think you can add him, I have no problem with it.” 9da3YW

Yue Xingwen nodded and looked at Xin Yan, “Xin Yan, you’re not on the same floor as our course progress and we can’t team up directly. How about this, when you finish brushing up on the Faculty of Medicine’s elective courses, senior brother Zhuo Feng and us should be on the 3rd floor as well, and the Research Group will be expanded by then. We happen to be short of people, if you don’t have a fixed Research Group, can you consider joining us?”

He thought that Xin Yan would refuse and said ‘let’s talk about it later’, but he actually agreed, “Okay, I’ll see you on the 3rd floor.”

Ke Shaobin was a little bit happy, adjusted his glasses and said with a smile, “That’s great! We have another teammate in the Chemistry Department, and I think Xin Yan’s Infinite Spirit Lamp is particularly cool!”

Xin Yan nodded at Yue Xingwen and turned to go to the canteen to eat. As he passed Yue Xingwen, he suddenly said lightly, “You handled this matter of the Convention well.” tmQW8U

Perhaps that was why he had agreed to join the team. Yue Xingwen smiled and said to his back, “I wish you a smooth pass, see you on the 3rd floor.”

Zhuo Feng looked at the boy’s lean back, and always felt that Xin Yan’s temperament was a little gloomy. His cold white complexion looked like a vampire who had not been in the sun for a long time. He also spoke in a cold and indifferent way, and it seemed that he was not easy to get along with. However, as a ‘long-range magic output’ from the Chemistry Department, their team should have one, and in the later stage, when they arrived at the Faculty of Chemistry, he could also help, so Zhuo Feng did not oppose adding him.

Lin Manluo was a little bit worried, “I’m the only girl ah, and there are still very few liberal arts majors.”

Yue Xingwen smiled and reassured her, “Senior sister, don’t worry. The Faculty of Liberal Arts should be on the later floor. After the 3rd floor, we’ll mainly look for our liberal arts teammates and find a few more girls to accompany you.” EAZOB3

Lin Manluo laughed, “Alright! Let’s finish brushing up on the previous courses first.”

After a brief breakfast, seven people split up at the elevator door.

Chrysanthemum Garden.

Zhuo Feng and his two teammates went to the Faculty of Medicine on the 1st floor to retake the courses, and four of them went to the 2nd floor to the Faculty of Mathematics.

The moment the elevator stopped on the 2nd floor, an icy mechanical voice rang in their ears, “Welcome to the Faculty of Mathematics.” dd2 YU

As the elevator doors opened, Yue Xingwen was speechless and shocked by the scene in front of him——

On both sides of the wide corridor were high-tech LCD screens that covered the entire wall. At this moment, there were constantly jumping lines of formulas, dense and messy mathematical formulas that made the liberal arts students feel in awe on the screens.

In addition to the formulas written all over the wall screens, there was also a regular pattern of primary numbers of 0-9 arranged on the marble floor under their feet.

It was like a world made entirely of numbers. B3xXVd

In the center of the hall was a screen with the words <Faculty of Mathematics Class Schedule for the Week>. The four of them came to the front of the screen and looked up at the class schedule——

Liu Zhaoqing could not help but complain, “People who aren’t good at math have to kneel down when they see the class schedule!”

Yue Xingwen rubbed his temple gently, “I was okay at math in high school, but I enrolled in liberal arts in university and haven’t touched math in two years. Almost all the knowledge I learned before has been returned to the teacher.” 3x0JIV

Under the large screen in front of them some female students lamented in a low voice, “I don’t even understand the class schedule!”

Someone else said, “Is there anyone who is good at mathematics who can take me on? If I can pass, you can have all the points!”

There was an uproar underneath the class schedule’s screen.

Ke Shaobin whispered, “We can ignore the elective courses for the time being, and just look at the compulsory courses. We missed yesterday’s class on Monday. Today is Tuesday, there is only one compulsory course, <Prime Numbers Maze>.” lNfDFy

Prime Numbers Maze? The three of them looked back at Jiang Pingce at the same time.

Jiang Pingce’s expression was calm and he said, “It should be a large three-dimensional maze related to prime numbers, which requires the use of prime number reasoning and some knowledge of three-dimensional geometry, it won’t be too difficult.”

Three people: “……”

You said it wouldn’t be too difficult, but it would be a nightmare level for others, right? F87swM

Yue Xingwen patted the other party’s shoulder lightly, “I’m counting on you.”

The four of them walked to the tablets placed side by side and pressed the <Select Course> button.

A prompt popped up on the screen——

[Faculty of Mathematics Compulsory Course: Prime Numbers Maze] WmyJk7

[Examination Room Rules: Limited course for the Research Group, must register as a Research Group]

[Course Description: This is a three-dimensional maze composed of prime numbers. Prime numbers, also known as a prime, is one of the natural numbers greater than 1 that has no more factors other than 1 and itself, can only be divided exactly by 1 and itself.

The twin prime numbers’ conjecture, proposed by Hilbert in 1900 at the report of the International Congress of Mathematicians—— There are infinite multiple prime numbers P, so that P+2 is also a prime number. wHrtcG

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

[Examination Requirements: Get out of the maze in 4 hours]

[Additional Question: Collect all Twin Prime Numbers, score +20]

[Note: At least one science major with strong computing ability is recommended in the Research Group] YOH5Mg

[Confirm Course Selection: Yes/No]

Yue Xingwen looked at Jiang Pingce, “Confirmed?”

Jiang Pingce nodded, “En.”

Yue Xingwen put his hand on Jiang Pingce’s shoulder and joked, “I have to follow you closely, you can lead me later. If I get lost in the Math maze, I can’t get out.” PbK7IY

Jiang Pingce’s lips were raised slightly, “Rest assured, I won’t lose you.”

The mechanical voice rang in their ears——

[C-183 Research Groups has successfully selected a course. The exam will start at 8 o’clock on time, please be prepared.]

Translator's Note

A Fourier series is a sum that represents a periodic function as a sum of sine and cosine waves. The frequency of each wave in the sum, or harmonic, is an integer multiple of the periodic function’s fundamental frequency. Each harmonic’s phase and amplitude can be determined using harmonic analysis.

  1. …maybe I don’t feel as stressed here because I myself did engineering maths in uni lol. Its pretty basic stuff.

    I guess I’ll start panicking when they reach the faculty of liberal arts.

    Thanks for the chapter!

  2. When the mc proves your point about using math 🤣 my mom (Asian ofc) said, “Math is very, very important, you use it a lot as an adult, and everything you learn in math will be needed in some way ”

    Thank you for the chapter ❤️

  3. I was in 10th grade when I last looked at a maths textbook! Now I only know the basics like addition, multiplication, etc. and how to calculate percentage… ꒰⁎×﹏×⁎꒱՞-

  4. It seems they were lucky to miss the Monday class. Already at 5 credits! Would that be a 75% fail rate?

  5. QAQ that math is so painful to look at, I think I went into a daze reading it fognskkd

    What a fun story this is! I love how the students work together and are so relatable ahahaha!

    Thank you for these wonderful chapters! ☺️☺️☺️☺️☺️☺️☺️

  6. I can relate to YX – I had a Physics minor in Uni but that was centuries ago. I don’t think I could differentiate an equation anymore.

  7. I think I get it? I know this much lol but I feel like I’m definitely gonna lose my braincells if they added more of maths other than prime numbers and a few other easy topics. I haven’t done maths in 4 years 💀💀 I’ve also returned what I learnt to my teacher 😔
