After being reborn, I gained a childhood sweetheart who appeared out of nowhere.

Monday, in the classroom.

The math teacher walked in with the test papers. The old man put the test papers on the table and called out, "Class representative, come up and distribute the test papers."

"Holy crap, Old Man Wang has already finished grading and handed out the test papers?" Wang Xu said. Their math teacher was named Wang Hong, but because he was very old-fashioned, he was nicknamed Old Man Wang.

"That's normal. Math tests aren't hard to grade," Lin Chuan said.

Over the weekend, grading exams is relatively easy for teachers, except for history and politics exams, which take longer to grade. The Chinese exams, on the other hand, take the longest, since each Chinese exam includes an 800-word essay.

Wang Xu rubbed his hands together. "I'm wondering if I can pass this time!"

"Have some ambition, will you? Let's round it up to a hundred points?" Lin Chuan asked.

"I feel like the questions were a bit difficult this time. The last two big questions were probably beyond the syllabus, right? I asked Zhao Jiajia, and she said she couldn't even solve the last question." Wang Xu sighed. Although Zhao Jiajia was always laughing and joking, her grades were surprisingly good in their class.

"How about we take a gamble? I'll bet you can get a perfect score?" Lin Chuan asked.

Wang Xu hesitated, clearly lacking confidence in himself, or rather, he was inherently a person with little confidence. Even if there was a high probability that he could pass the exam, he would still be extremely worried.

"What score do you think you can get?" he asked in return.

"It should be between 120 and 125," Lin Chuan stated a precise range. "What? You want to bet on my score again?"

Wang Xu seemed somewhat tempted.

"How about this, since I won last time, you only need to treat me to lunch if you lose this time, and I'll treat you to two meals if I lose. How about that? Don't you want to get revenge?" Lin Chuan coaxed patiently.

Wang Xu was still hesitant, but he had a humiliating experience with the last diagnostic test.

"Hurry up, the test papers will be handed out soon," Lin Chuan reminded him.

At this moment, Zhou Yun was handing out thick stacks of test papers one by one. She didn't know when it was their turn, but as soon as Lin Chuan finished speaking, Zhou Yun walked directly towards them.

"The class representative is here," Lin Chuan said.

"I'll bet, but not 100 points, it's 120 points, just like you said." Wang Xu raised the bar.

"No problem," Lin Chuan readily agreed.

Seeing how quickly they agreed, I feel like I've fallen for their trick? But this test was really difficult, wasn't it? How could I possibly get 120?

"You've seen the results, haven't you?" Wang Xu suddenly realized something.

"I swear on my integrity, absolutely not." Lin Chuan shrugged.

At this moment, Zhou Yun walked up to the two of them and handed them the test paper. It was Lin Chuan's test paper. "Class monitor, your test paper."

"Thank you," Lin Chuan said, but before he could even reach out to take it, Wang Xu was even more eager than him. He snatched the test paper, took a deep breath, and looked even more excited than when he saw his own.

He slowly unfolded the test paper in front of him, glanced at the score: 125 points.

His vision went black instantly, and he felt as if the sky had fallen.

"When did you become so good at math?!" Wang Xu said with a bitter face. More than Lin Chuan's score, he was surprised that the other could calculate his score so accurately after the exam.

"The answers on the math test are all standard. Don't you know whether you got them right or wrong?" Lin Chuan said. "I certainly do."

"what?"

"The hair test is finished, and you've all seen your scores. Now I'll talk about your math scores," Wang Hong began, and the classroom fell silent.

"Your average math score was relatively low this midterm, only 85 points, but this result was expected, since some of the questions on this test were a bit beyond the syllabus," Wang Hong paused for a moment, "but there were still some students who got full marks this time."

Everyone looked at each other, and finally their eyes unconsciously fell on Chen Xiyu. If anyone could get a perfect score on this kind of difficult test, it would be her.

"Chen Xiyu got a perfect score in math," Wang Hong said, eliciting a gasp of amazement from the classroom.

"You're amazing! You even managed to solve the last question." Zhou Yun looked at her deskmate's test paper and couldn't help but say. As the class representative, she only scored 128 points, mainly because she lost points on the last question.

"I happened to have done a similar problem before," Chen Xiyu explained.

"Which question do you think is the most difficult?" Wang Hong asked.

"The last big question, teacher," the students said in unison.

"The last big question was a bit complicated, and some of the content was things you hadn't learned before, so it's normal that you couldn't solve it. In our class, only Chen Xiyu and..." Wang Hong paused, "and the class monitor solved it."

Everyone couldn't help but applaud.

"Quiet down," Wang Hong waved his hand, his gaze falling on Lin Chuan with a hint of scrutiny. "Class monitor, I want to ask you, why did you only write a few answers for the last question? Why didn't you show the solution process?"

The others were taken aback, because the statement sounded a bit strange. Writing only the answer without showing the process is rare in math exams, as the process also accounts for a significant portion of the score.

No one would answer the question like that unless you cheated. When Wang Hong saw this answer, he had the same thought in his mind, but he didn't say it directly. At the No. 1 High School in the city, cheating is a very serious matter.

After all, even among the top students, not many could solve this problem completely.

"The process was calculated on scratch paper, but there wasn't enough time, so I didn't write it down," Lin Chuan explained.

"Then could you come up on stage and write down your solution process?" Wang Hong asked, adjusting his old-framed glasses.

Lin Chuan hesitated for a moment.

Wang Hong frowned slightly when he saw Lin Chuan hesitate for a moment. If the other party could really solve the problem again, he could let it go. But if he couldn't even solve the problems he had done before.

"Never mind, you probably just forgot because it's been so long," Wang Hong said.

He didn't delve into it in public. Some things could be verified after class. Besides, the homeroom teacher had a very high opinion of this class monitor. He planned to call him to his office after class and give him another "chance".

The students in the class looked at each other in bewilderment. Some of the quick-thinking students seemed to understand the math teacher, while many others looked at Lin Chuan with surprise and doubt.

People were whispering.

"Does Lao Wang mean the class monitor cheated?"

"Really? The class monitor doesn't seem like that kind of person."

"Hey, people can fake it..."

"Alright, quiet down, let's start going over the test paper." Wang Hong patted the podium and picked up his lesson plan.

"Teacher, I can write out the solution process," Lin Chuan said, raising his hand.

Wang Hong was taken aback. "Then come up here."

Lin Chuan stood up, walked directly to the podium, picked up the test paper and chalk, and began answering the questions on the blackboard without any hesitation.

However, when he wrote out the solution, the students below the stage all looked puzzled because they couldn't understand the solution process or the strange formulas at all.

Less than a minute later, Lin Chuan put down the chalk, turned to Wang Hong and said, "Teacher, I've finished answering the questions."

"How do you know this? This is advanced mathematics, right?" Wang Hong glanced at the solution process and found that it was all university-level advanced mathematics content, including Taylor series expansion and L'Hôpital's rule.

"I have a cousin who is currently in college. He gave me a lecture a while ago and mentioned a similar problem to me inadvertently," Lin Chuan said. "Since it wasn't a standard solution process, I didn't write it out."

Wang Hong nodded, then turned to look at the other students. "Classmates, the class monitor's method of solving the problem is correct, but he used university-level mathematics knowledge, that is, advanced mathematics."

The students in the class looked at Lin Chuan with some surprise. Everyone else was learning derivatives in the inter-degree interval, so how come the class monitor had already started to get into university mathematics?

"This problem-solving process is faster, but it's best not to use it in the college entrance examination. High-altitude exercises require the use of high school knowledge points, and using this method is likely to result in point deductions," Wang Hong said. "So you must not follow the class monitor's example."

"Teacher, we want to learn, but we need to know college-level math. I didn't even understand high school math," Zhao Jiajia said.

Everyone laughed when they heard it.

Wang Hong looked at Lin Chuan and said, "Squad leader, you can go now."

Lin Chuan stepped down from the podium, under the watchful eyes of everyone.

"You don't need to learn the class monitor's solution process. I'll explain the common problem-solving process and thinking methods used in high school..." Wang Hong picked up the chalk and began writing next to Lin Chuan's answer.

"You actually know college-level math?" Wang Xu looked bewildered. "You've been hiding your true abilities."

"I didn't hide it either," Lin Chuan said.

"But I still refuse to accept this!" Wang Xu shouted. "In PE class, I challenge for a one-on-one one-on-one basketball game. I'm going to win back everything I've lost!"

Lin Chuan chuckled, "Be careful you don't lose even more."

After Old Wang finished explaining the test paper, it was lunchtime and school was over. He added one last thing: "If you still don't understand something, ask the classmate who got it right, or ask me during evening study."

Lin Chuan and Wang Xu walked outside together, preparing to find something to eat.

"Class monitor, how come you know college-level math?" someone said sinisterly behind him.

Lin Chuan turned around and saw Zhao Jiajia and Cheng Xue, with Chen Xiyu beside them. It seemed like a group of people were going out to eat together.

"I had a cousin who taught me a little bit," Lin Chuan said without changing his expression.

"You have a cousin? How come I didn't know?" Chen Xiyu tilted her head and looked at him, asking a question that seemed to have a profound meaning.

Lin Chuan almost forgot that he still had a childhood sweetheart.

"There really is one," Lin Chuan could only continue, "but you haven't met him because we're not familiar with him. He doesn't come to our house often, we only see him a few times during the Chinese New Year."

"Really?" Chen Xiyu's face was full of doubt.

"Really, really," Lin Chuan didn't want to continue the topic, as it would give him away. "Let's go eat, or we'll have to wait in line again."

"Let's go, I'm starving," Wang Xu said.

A large group of students arrived at the cafeteria. After getting their food, they sat down at a long table and ate. Wang Xu looked left and right, feeling that every student who walked by would glance at them.

But that's normal, after all, this table is filled with Chen Xiyu, Cheng Xue, Zhao Jiajia and Zhou Yun... This is the strongest lineup in their class, and boys from other classes are drooling when they see it.

Everyone ate and chatted, but not many people talked about studying. Instead, they talked about gossip about their teachers, anime, and novels.

Wang Xu suddenly turned to Lin Chuan, as if remembering something. "Old Lin, speaking of novels, I read one recently, and it was pretty good."

"I probably don't have time to read novels right now," Lin Chuan said.

"Hey, you should really go check it out if you have time," Wang Xu said.

"Is it very good?"

"It's good-looking, but mainly I feel that the male protagonist in the novel looks a bit like you," Wang Xu said.

"Like me?" Lin Chuan asked.

"At times, the male lead makes me feel like it's you speaking, just from the tone of your voice," Wang Xu said.

"What novel?"

"It's a serialized online novel called 'My Girlfriend is a Cat'."

Lin Chuan's eyes twitched slightly, but his expression remained calm.

"Hey, I've read this novel too," Zhao Jiajia said. "Now that you mention it, I also think the main character is a bit like the class monitor."

"What book?" Chen Xiyu, who hadn't said much until now, seemed to have become interested.

Zhao Jiajia took out her phone, opened her reading history, and then passed it around to everyone. A group of people gathered around the phone and started discussing it.

"To be honest, this story is really good, and the author's writing is excellent," Wang Xu said.

"Yes, yes," Zhao Jiajia said, "Xiaoyu, you can take a look when you get back. It's about a male protagonist who meets a cat that can understand human speech."

"Okay." Chen Xiyu nodded.

Even Chen Xiyu, who doesn't read online novels, came over to watch the fun. The topic changed from complaining about the teacher to a novel discussion, and it happened right in front of the author. Lin Chuan could only concentrate on eating, completely acting as if it was none of his business.

"Old Lin, do you still read novels?" Wang Xu asked.

"I'm basically not going to look at it anymore, I need to study." Lin Chuan said seriously.

"Oh, you can take a look at this book when you get back," Wang Xu said.

Lin Chuan nodded, "I'll take a look when I have time."

In the end, everyone just discussed it, and since no one except Chen Xiyu knew that he was writing a novel, no one would think about it in that direction.

In the afternoon, they handed out the physics and politics test papers. Lin Chuan glanced at his scores and found that he scored in the 70s and 80s in both subjects, which was expected, since he had listened attentively in class.

But he spent all his time writing novels after class, so he didn't have time to read books at all, and he didn't have any strange ability to remember everything he read, so this grade is quite normal.

After evening study, Lin Chuan and Chen Xiyu walked home together as usual, without exchanging a word.

"Did you write that book?" Chen Xiyu's voice suddenly came from behind.

Lin Chuan paused, turned around, and of course knew what book she was referring to. "Why do you ask?"

Chen Xiyu said with a smile, "It's a girl's intuition."

"The girl's intuition is really scary," Lin Chuan thought to himself.

"Of course, I watched it this afternoon and I also think the main character looks a bit like you," Chen Xiyu said.

"No, how could I write this kind of romance novel? I write fantasy novels," Lin Chuan said.

"Really? But I checked, and the author updates every time after our evening study session." Chen Xiyu leaned closer, looking directly into his eyes, as if trying to find a trace of panic in them.

"Maybe it's because the other person is also a student?" Lin Chuan said. "There are so many novelists, coincidences are still possible."

The two stared at each other for a while, but Chen Xiyu couldn't see any panic on Lin Chuan's face, so she could only give up helplessly in the end, "Okay."

Lin Chuan also breathed a sigh of relief. Today was a bit awkward; he almost got exposed. He had seen all sorts of situations over the years, but he really didn't want to be exposed no matter what.

Besides, he wasn't a great writer; he just wanted to write novels to earn some "small money."

Back home, Lin Chuan sat at his desk, turned on his computer, and prepared to publish a new chapter. But remembering Chen Xiyu's words, he deliberately waited until the last two minutes before publishing it.

When I opened the book club group, I found that there were quite a few more readers applying to join the group today. Just as I was about to accept their applications, I saw a few familiar avatars and IDs.

Lin Chuan pulled out his phone and checked. Good heavens, Wang Xu, Zhao Jiajia, and Zhou Yun had all requested to join the group. He even saw Liu Hao, who hadn't spoken in a long time, was there. It seemed someone was promoting the novel in the group.

This isn't a reader group, it's a class group!

Scrolling to the bottom of the application list, Lin Chuan suddenly saw an extremely familiar profile picture—it was Chen Xiyu.

Lin Chuan sighed, hesitated for a moment, and then "let" all these people in. After all, not accepting them would be like burying his head in the sand, and suddenly many people would join the reader group.

It started to get lively again, with old group members saying "Welcome, welcome," and new group members starting to chat and joke around.

"Author, are you a student?" Zhao Jiajia asked as soon as she came up.

"Um."

"High school student?"

"College student."

"Really?" Wang Xu asked again.

Lin Chuan thought for a moment, "Of course it's true. By the way, the extra chapters I promised you might have to be postponed. I'm preparing for the CET-4 and CET-6 exams soon." He calculated that he should be taking the CET-4 and CET-6 exams soon.

"What are CET-4 and CET-6?" Wang Xu asked.

"It's a university English exam," Lin Chuan explained.

Later, he talked about his college life and daily routine. After all, he had actually been to college, and he spoke eloquently and logically, which quickly convinced everyone. Some readers reminisced about their own college life, while others looked forward to it.

Chen Xiyu joined the group but didn't say much, only sending a smiley face emoji.

Then I noticed a private message, and when I opened it, it was from Liu Hao?

"Author, you write really well! Keep up the good work!" Liu Hao said.

"Thanks."

"I really like your book, you must finish it! Don't abandon it!" Liu Hao said. "I'm short of money right now, but I'll have some to tip you at the end of the month."

Lin Chuan looked at the other person's enthusiastic manner and didn't know how to respond for a moment.

Especially imagining Liu Hao's face sitting on the other side of the screen, it felt a bit strange, but all I could do was reply with a smiley face.
