Lin Chaoxi didn't know where Lao Lin's determination came from, but it was probably just to make her feel at ease.

Vice President Zhang gave them the power of independent learning, and they no longer had to go to the reading room to read.

“Even the simplest questions can be analyzed clearly. What is the unknown quantity? What is the known data? How is the unknown quantity related to the known data?”

Different from the way they were used to doing exercises, Lao Lin had different requirements for their exercise training. He did not ask for accuracy or speed, but for ideas.

Write down your solution before solving a problem. This is a process of slowing down when pursuing speed training.

Many of the questions were too basic for Lin Chaoxi, but since Mr. Lin required everyone to do them, she did not exclude herself.

From number theory to geometry, from solutions to proofs...

After writing the last answer, she looked up and saw the street lights outside the window were already on.

It's already night, isn't it? As she thought this, the sounds around her surged in like a flood.

A bowl of mung bean porridge was put down, just right on top of the target score.

Lao Lin brought them dinner. He said nothing but quietly scooped out the porridge and put it into small bowls.

The other children were immersed in their own world, still concentrating on doing their homework, only Pei Zhi put down his pen.

Lin Chaoxi went over to look at his exercise book and found that the book had been turned to almost the end. She signaled to Pei Zhi that she wanted to look at his exercise book, and Pei Zhi nodded in agreement and sat back.

She leaned over and flipped through the book from beginning to end, and found that Pei Zhi was not doing the exercises selectively according to what Lao Lin had chosen. He did all the exercises from beginning to end.

Although the handwriting is still childish, the problem-solving process is meticulous.

Even if he knew the answer to a question at a glance, he would still follow Lao Lin's instructions and write out the entire process in detail.

The little boy's breath fell on the top of her head as Lin Chaoxi turned the last page.

"All done?" she asked quietly.

"Yeah, there's nothing to do anyway."

Anyway, nothing to do...

Lao Lin put down the last bowl of porridge and looked at them with narrowed eyes.

Lin Chaoxi quickly stood up and wanted to help Lao Lin distribute the porridge to the other children.

"I'm going to get some steamed buns." Lao Lin said specifically.

Lin Chaoxi wanted to keep up.

"You sit down." Lao Lin said to her, then he nodded at Pei Zhi and said, "You follow."

The two walked around and came back.

Lao Lin had an extra bowl of steamed buns in his hands, and Pei Zhi began to put away the books on the table.

Lin Zhaoxi: "What's wrong?"

"Master asked me to switch positions with Yao Xiaotian."

"Why?"

"He's so free, he can teach others." Lao Lin said so. Yao Xiaotian's seat was just at the other end of the long table, a thousand miles away from her.

Lao Lin took a steamed bun and stuffed it into Pei Zhi's hand, telling him to sit there and eat it.

Lin Chaoxi looked at Old Lin and found it unbelievable.

"What are you looking at? Primary school students shouldn't fall in love too early," said Lao Lin.

——

Changing seats is just a small episode in the stressful study life.

Most of the time they were doing exercises. Lao Lin was very determined to assign a large number of questions, and everyone had to devote their whole heart to them.

"Teacher Lin, in this permutation and combination problem, they all look the same!" An Beibei shouted.

"What's the difference?"

"They all look like noodles to me, in bunches."

"I see..." Lao Lin snapped his fingers, put the permutation and combination exercises together, and asked, "What do you think it looks like now?"

"What?"

"Of course it's a bowl of noodles." Lao Lin smiled.

"Teacher, you were not like this before. You have changed!"

Stimulated by Lao Lin's sneer, the children burst into wailing, but after they finished shouting, they buried their heads in calculations again, as if they were not the ones who had just complained about too many questions.

In fact, even elementary school students know that there is no shortcut to improving grades in a short period of time except doing a lot of practice questions.

As for mathematics, a lot of practice and repeated consolidation are the best ways to become proficient in using the tools.

——

4th day to last.

"An Beibei, 78."

"Chen Chengcheng, 83."

"Yao Xiaotian, 75"

"Lu Zhihao, 82"

…

In class, every time Xie Ran announced a grade, there would be exclamations from the class.

Except for the person involved, other students were very surprised at their rapid improvement in performance, especially Chen Chengcheng who had always been bullied by Zhang Liang and his friends.

In the two tests on the 5th and 6th, Chen Chengcheng's scores exceeded the average scores of the first group and were higher than the scores of the students Zhang Liang found to fill his position. This means that Zhang Liang kicked out the member with good grades and replaced him with one with poor grades.

"Don't you know how to do this problem? Why did you get it wrong? Do you know how much our average score has been dragged down?"

When the class was over, Zhang Liang's voice of criticism was particularly loud.

"Chen Chengcheng, you are amazing! How did you learn this?"

At the same time, there was also the sincere praise from little Lu Zhihao.

Zhang Liang glared at Lu Zhihao with his eyes wide open, while his gang of followers were also pressed on the table, as if they were ready to quarrel at any time.

Lin Chaoxi tapped the table with his five fingers, glanced at teacher Jie Ran outside the window, and smiled at them.

Jie Ran turned around to look at them. Zhang Liang felt so uncomfortable that he could only sit back in his seat and slammed the desk hard.

From beginning to end, Chen Chengcheng didn't say a word, just looking at the wrong questions on his test paper.

After he said he wanted to get 85 points that day, he became very quiet and worked silently towards his goal. Naturally, this silence also infected others.

——

In a corner of the cafeteria, sunlight shines through the glass window, the ceiling fan is spinning rapidly, and the rustling sound of pens fills the entire corner.

Except for going to the reading room for an exam at 5:30, they stayed here all the time. The cafeteria is not a very good environment for studying, so there are always parents with children staying around them.

“Can you read in here?” parents always ask this question.

Lin Chaoxi had already found the best solution, so he was sent by his friends to the outside to deal with various people.

Without looking up, she handed over a note.

The parent who asked the question took it and saw that there were several lines of large characters on it, answering all the questions she wanted to ask and would ask next.

——【You have to read it even if you can’t understand it】

——【If you are not good at studying, you can only study in the cafeteria】

——【Why should we study mathematics? 】

——【Because math is fucking interesting】

When parents see these answers, they sometimes just walk away with the notes in a daze.

"Auntie, give it back to me, give it back to me, I just wrote this, it's still new!" Lin Chaoxi would always chase after her and shout.

In fact, after staying there for a long time, you will find that it doesn’t matter where you study. As long as you immerse yourself in it, the environment will not affect you at all.

——

3rd day to last.

The closer it got to the midterm exams, the more nervous the kids became every day when the scores were announced.

The average score will be included in the total average score. Even a difference of 0.5 points may determine whether you stay or leave, so everyone cares about this very much.

"Pei Zhi, 99."

"Lin Zhaoxi, 97."

"Lu Zhihao, 80."

"Hanamaki 75.5."

…

After a round of results were reported, Lin Chaoxi went up to take back the 12 test papers and distributed them.

Of course, the classroom was also filled with the exclamations of other students and the praise of the teacher, and the lake breeze was refreshing.

But the moment they received the test papers, they became quiet and looked at their own answers. Other voices could no longer be heard.

Because their grades improved dramatically, many people came to ask them about their study methods.

——Actually there is no real way, we just study more seriously.

When asked, Lin Chaoxi answered sincerely, and then was treated as a show-off and beaten up.

Of course there were other students who wanted to join them, but Jie Ran said that they were forced to form a temporary group because they violated the rules. It was totally fine if you wanted to join, but you had to be averaged with them.

"...You have to get the highest average score in the class to stay. Otherwise, you will be eliminated."

Jie Ran did not mention Zhang Liang, he just changed the wording, but everyone knew that to get the highest average score in the class, the group had to surpass Zhang Liang's group.

Considering that this group is actually a real alliance of poor students, although they have made great progress, their scores are still far behind those of the top students. After hearing this, many students stopped asking questions.

——

Although Lao Lin set goals for them, he did not actually ask them to reflect on how far they still had to go.

But each of them still had a lot of ambition in their hearts, always calculating the gap between their current performance and that of Zhang Liang and the others.

"I'm the one holding everyone back. If I could get 85 on the test..."

2nd to last day.

Lu Zhihao calculated the average score, pursed his lips, and spoke seriously.

In the noisy classroom, Zhang Liang and his friends laughed at them. After learning that they had to get first place in the exam to avoid being eliminated, Zhang Liang's attitude changed 180 degrees.

“You guys want to surpass us too,” his face was full of these words.

There are still two days before the midterm exam. The average score of the 12 groups is 80.5. For the Poor Students Alliance, there has been a full ten points of improvement from an average score of over 70 to the current level.

Unfortunately, the average score of the first group was 85, which was much higher than theirs. The 5-point improvement from 80 to 85 is much more difficult than the improvement from 70 to 80.

At lunch time, they summarized their exam thoughts in the cafeteria as usual.

"My thinking was right for this question, but I forgot to add this point when I was doing it at the end." An Beibei was very upset. She scooped a large spoonful of celery and chewed it without even looking at it. "Otherwise, I would have scored 90 points."

"It's all because of my carelessness." Huajuan held his head, holding the test paper in one hand and a spoon in the other, "I can even make a mistake with this carry!"

"I don't know how to do this question." Yao Xiaotian looked at Lao Lin who was sitting next to her and said, "Teacher, should I do more questions of the same type?"

The children reflected on themselves one by one, as seriously as a salesperson whose performance did not meet the target would do to his boss.

Lao Lin glanced at them, drank a sip of soup, and said, "No, it's mainly because she didn't get a perfect score."

Lin Chaoxi was hit on the back of the head by Lao Lin. He covered his head and admitted his mistake: "I was careless. I only got 92."

After she finished speaking, the other eleven people at the long table put down their cutlery and glared at her, including Pei Zhi.

"You deserve a beating, right?" Lao Lin laughed.

Comrade Xiao Lu nodded vigorously, which was a rare move.

"You guys are just as self-reflective, but you deserve a beating too," said Lao Lin. "Why don't you see the progress you've made, but instead you're obsessed with your mistakes? Not only are you unhappy, but you're also causing a lot of psychological pressure on others."

"Because... because..."

"Because we have been taught since childhood that wrong answers are wrong and we should reflect on them seriously," Pei Zhi said.

"Don't we need to reflect on the right questions?" Lao Lin asked, "Why did we succeed? Which idea was the most ingenious? The experience of success is also very important."

Pei Zhi nodded: "You are right."

Old Lin turned the spoon and pointed at Yao Xiaotian and said, "I want to praise Yao Xiaotian for taking the initiative to ask to do more exercises. Then, should everyone do more exercises this afternoon?"

When they heard that there was another question to do, the children cheered loudly and no one was unhappy.

Extremely perverted.

Lin Chaoxi smiled and stuffed a big mouthful of carrot into his mouth, and started chewing it with a crunching sound.

It is hard to say what ability Mr. Lin has that can help children make great progress in a short period of time.

In fact, the first is mentality, the second is attitude, and the third is ability.

——

The day before the exam.

The gap between them and the first group has narrowed by two points. Even so, it still seems unrealistic for the Poor Students Alliance to overtake the first place.

But no one was beating their chest or feeling sad about getting the questions wrong anymore; even the annoying Zhang Liang team disappeared.

Everyone was busy with their own work. Those with a weak foundation did basic questions, while those who wanted to get high scores did difficult questions. Even Pei Zhi followed Lao Lin's request and tried to prove all the formulas and theorems in various ways.

Making good use of time doesn't mean they are nervous.

During lunch, Lao Lin brought out a very interesting question for everyone to play with.

The question basically said -

A bear starts from point P, walks one mile due south, then changes direction and walks one mile towards the whole building. Finally, it turns left and walks one mile towards maintenance. At this point, it arrives at the starting point P. What is the color of the bear?

"What color? How many colors can bears have?"

"Black, white, or brown?"

"Don't forget the giant panda?"

"But it seems that only the Arctic is special because polar bears are white?"

"And how can you get back to the original place by walking this way? So this sinister question must be asking whether point P is at the North Pole?"

"Still want to calculate?"

"Let's do the math, let's do the math."

The children were discussing one after another, and soon they took out their pens and started drawing.

Finally, everyone worked together and found that Lao Lin was just fooling them.

There are two cases for p. It may be at the North Pole or it may be a point near the South Pole.

"Are there bears in Antarctica? Teacher Lin, you lied to us!"

"It's to let you know how evil people are." Old Lin laughed.

Just like that, the leisurely lunch time passed, and in the afternoon the children went over the knowledge points again.

The last day of study ended in such a dull manner.

At ten o'clock in the evening, Lao Lin urged them to go back to bed on time.

"Master Lin, can I interview you?"

Lin Chaoxi stayed and had something to discuss with Lao Lin. She pretended to raise the microphone and asked Lao Lin.

At that time, Lao Lin had just thrown all his clothes into the laundry sink outside the house to wash them, and the stars were shining brightly in the suburbs.

"Why are you interviewing me? Why are you so patient? I wonder how you knew you were my daughter?"

The faucet hit the pool with a splash. Lin Chaoxi opened his mouth, and his mood was the same as the water in the pool.

After returning from the appraisal institute that day, Lao Lin never asked her about her father-daughter relationship once. She thought Lao Lin had forgotten about it long ago or was just keeping it to himself. But she never expected that Lao Lin would bring up all sorts of issues without her being prepared at all.

Clearing his throat, Lin Chaoxi said, "Do you want to know? If you want to know, I can tell you."

Lao Lin: "You had a dream in which you knew you had a father. Your birthday and the affinities of numbers appeared in the dream, so you went to No. 284 Zhuanzhu Lane to confirm the facts. You found that the person who walked out was exactly like the one in your dream, which made you more certain of the reality of the dream..."

There were slight insect sounds in the yard, and a mosquito was sucking blood on her arm, but Lin Chaoxi could only stare blankly at Lao Lin, unable to do anything.

For a moment, she suspected that Lao Lin had misunderstood her like Professor X, otherwise why would he repeat her story exactly as it was.

Old Lin smiled meaningfully, and Lin Chaoxi recovered a little.

She covered her chest and said, "Dad, if you say this, I will not do well in the exam tomorrow."

"Have you ever thought about this?" Lao Lin turned off the faucet and spoke calmly.

"What did you think?"

"No matter what the appraisal result is tomorrow, as long as tomorrow comes, I will never hear the real story."

The real story, of course, is how she knew they were related.

So should we choose this time?

In the night, Lao Lin's face was filled with indescribable meaning.

At that moment, Lin Chaoxi really wanted to tell Lao Lin everything, but the more rational part of her body held her back.

She will eventually leave here and return Lao Lin to Xiao Lin Chaoxi.

She couldn't cause any further trouble to the world, and she knew it very well.

The starry sky was shining overhead, and my father's eyes were filled with love and calmness.

Lin Zhaoxi shook his head and said, "I really just had a dream. I dreamed that I fell into a rabbit hole. There was a deck of playing cards in the rabbit hole. The Queen of Hearts told me that I had a father..."

"Is that so? Why does it sound familiar?" Lao Lin tapped her forehead with his wet hand and said, "Go back and have a rest early."

Lao Lin said this.
