Reborn in the 1980s as a top student

Chapter 128

Lin Yin just mentioned several raw materials, and the three brothers helped Lin Yin find them. It is not difficult to make chalk, but the difficulty is to keep it dust-free.

After Lin Yin made it, because there was no blackboard at home, he had to go to school to experiment.

Teacher Sun was very curious when she learned that Lin Yin was going to make dust-free chalk. She felt that Lin Yin was not only smart, but also smart and practical, so she joined the team.

Lin Yin and everyone worked together to make three types of chalk overnight, which were rough in appearance but snow white in color.

Lin Yin took the first piece of chalk and wrote two words on the blackboard. The handwriting was clear, but it was too soft to do.

Lin Yin picked up the second type of chalk and wrote two words on the blackboard, but before the word was finished, it broke with a click. This powder is very similar to the chalk used by the teachers in the school. It has a lot of dust and is easy to write. It's not smooth, or it doesn't pass.

Lin Yin picked up the third type of chalk. The writing was smooth and clear, and the powder was not too much. Lin Yin's eyes lit up and he felt that it was okay.

However, it is still not as good as the feather brand chalk she used in her previous life, but this powder is much better than the chalk used by the school teacher.

Teacher Sun stood aside, also excited, and said in surprise, "Lin Yin, this piece of chalk is really good, even better than the ones distributed in school."

Lin Yin nodded, anyway, there are still some materials, I have to try again.

Teacher Sun patted Lin Yin's small shoulder and said comfortingly, "It's already very good. You are only 9 years old this year. Many children like you are still playing in the mud. Don't put too much pressure on yourself."

Lin Yin smiled and nodded, "Thank you, Teacher Sun, I understand."

At noon the next day, Lin Yin was about to go to school, and it was Lin Aimin who went to see Lin Yin off.

Walking on the road in the village, the villagers saw their father and daughter greeting each other with smiles. When they learned that Lin Yin was already in the third grade of junior high school, many villagers were surprised and looked at Lin Aimin with envy. The four children of Aimin's family are really sensible, especially the youngest one, who is only nine years old this year and is in the third grade of junior high school. This is too smart.

Lin Aimin enjoyed everyone's envious eyes all the way, not to mention how happy he was.

When the father and daughter were about to leave the village, they unexpectedly ran into Yang Liu who was returning to the village.

Lin Yin hadn't seen Yang Liu for a long time. At this time, Yang Liu was wearing a red floral gown, a pair of black trousers, and two braids, looking at Wen Wen quietly.

Yang Liu also saw Lin Yin's father and daughter, his complexion changed immediately, he quickly lowered his head, and hurried back to the village from the father and daughter.

When they arrived at the school, Lin Aimin told Lin Yin to enter the school quickly, and he turned to leave.

It's not too early now, and I have to rush home, otherwise it will be dark when I get home.

Lin Yin looked at Lin Aimin with some distress. When he came, Lin Aimin carried her on his back for a while. He had just sent her to school and had to go back quickly. Lin Yin made up his mind to find a way , Earn a bicycle for the family.

With the mosquito coils made by Lin Yin, the people in Lin Yin's dormitory have never been bothered by annoying mosquitoes when they sleep at night. People in other dormitories are envious and want to snatch Lin Yin to their dormitory.

Lin Yin still tells stories every night, but the time is greatly shortened.

Zhao Yanan originally said to visit Lin Yin every other week, but Lin Yin was reluctant to let Zhao Yanan go back and forth to see her at school. After all, their home was too far away from the school. The road is not good, it takes too much time.

Lin Yin is continuing her own research while studying.

Another two weeks passed in the blink of an eye. On the second Thursday and Friday, the school held monthly exams, and Lin Yin answered very easily.

It was a holiday on Saturday morning, and Lin Aimin came to pick up Lin Yin.

Lin Yin has been conducting her own research for the past two weeks, looking for ways to improve chalk.

This time when she got home, she immediately took her three older brothers to make chalk. Lin Yin is undoubtedly very smart. After her unremitting efforts, she finally made a chalk that is easy to use and has less chalk dust.

Lin Yin and her three elder brothers made a lot of chalk. Lin Yin asked the three elder brothers to send some to the elementary school, and she took the rest to the school.

During class on Monday, Mr. Zhou found that on the podium, there was a kind of chalk that was slightly longer and less round than the usual chalk. Mr. Zhou picked it up and looked at it curiously.

Lin Yin hurriedly said: "Teacher, this is the chalk I made. It is very easy to use and has less powder. You can try it."

Teacher Zhou looked at Lin Yin in surprise, "You made it yourself?"

Lin Yin smiled, "No, my three brothers also helped me a lot."

Teacher Zhou took a deep breath, looked at the smiling little girl in front of him, curiously picked up a pen, and wrote a few words on the podium.

The writing is smooth, the handwriting is clear, very good.

Teacher Zhou thought of Lin Yin and said: This kind of chalk powder is relatively small, and then I wrote some more words. I picked up the blackboard eraser on the table and erased the words on the blackboard. , but it is almost imperceptible.

Teacher Zhou looked at the chalk in his hand in surprise, then turned to look at Lin Yin, "Very good."

After being praised by Teacher Zhou, Lin Yin's face blossomed into another smile.

In the first class, when Mr. Zhou was in class, he used the chalk made by Lin Yin to write the formulas that filled the blackboard. After writing, he picked up the blackboard eraser and wiped it. When working on the blackboard, there is very little chalk powder, which hardly affects people.

After the first class, Mr. Zhou was going to teach the second class of students in the second class. Before leaving, Mr. Zhou couldn't help but took a few more pieces of chalk made by Lin Yin.

When they arrived in class two, the students in class two saw Teacher Zhou coming, and they didn't pay attention at first, but when they saw that Teacher Zhou was holding a few pieces of white chalk in his hand, they couldn't help but feel a little bit of doubt in their hearts. Was there chalk on the desk? ?Why did Mr. Zhou come to class with chalk?

The students in the audience didn't know, but Mr. Zhou could more and more feel the huge difference between the chalk made by Lin Yin and the chalk provided by the school.

The Chinese teacher in Lin Yin's class didn't pay attention at first when he was in class, but when he picked up the chalk on the desk and wrote on the blackboard, he couldn't help but let out a little gasp. The chalk writes too smoothly. , and the writing is clear.

The Chinese teacher didn't think much about it. After he finished the lesson, he had already written all over the blackboard. Then, when he was wiping the blackboard, the Chinese teacher realized that he didn't feel much chalk foam. Nose, wiping the blackboard with one hand, completely different.

The Chinese teacher looked at the chalk in his hand and couldn't help chuckling, "This chalk is really good!"

The Chinese teacher didn't know that the chalk was made by Lin Yin, but when he went to the second class in the next class, he felt that the chalk didn't feel right. When he wrote on the blackboard with a little force, the chalk would break, and Sometimes the handwriting is not very clear, and there is a lot of chalk foam.

The Chinese teacher couldn't help but said to the monitor of the second class, "there is a new batch of chalk in the school, which is very good. You should go to get some new chalk from the school next class. This kind of chalk is too difficult to use. Then This kind of chalk has less chalk foam."

The monitor of the second class didn't understand this either, so he nodded in agreement after listening to it. After the Chinese teacher finished class, the monitor went to get the chalk, but learned that the school had always used the original chalk, which had not been changed.

The class monitor was rather puzzled, but he didn't take it seriously, thinking that the Chinese teacher made a mistake.

Afterwards, every teacher who came to the first class was amazed at the ease of use of chalk. After all, teachers are the ones who deal with chalk every day, and they can easily perceive the difference between chalk and chalk.

A box of chalk made by Lin Yin was quickly used up. These teachers went to the school to inquire, but they learned that the chalk in the school was the same as before, without any difference.

Where did the chalk used in Class of the third grade come from?
These teachers approached Teacher Zhou, who smiled and said, "The school didn't buy those chalks, they were made by Lin Yin."

Because Lin Yin is good at studying and she is only 9 years old, she is considered a little celebrity in school, and all the teachers in the school know her.

The teachers of all subjects were surprised when they learned that the chalk was made by Lin Yin, especially the chemistry teacher couldn't help laughing, "This student Lin Yin is really amazing, few people can combine what they have learned with reality, she He is simply the little inventor of our school."

A school teacher asked Mr. Zhou, "Mr. Zhou, the chalk made by Lin Yin is so easy to use, can you tell that little guy about it? Ask her to make another batch."

Teacher Zhou pondered for a moment and said, "The chalk made by Lin Yin is very useful, but she is now a third-year junior high school student. I think her most important task at present is to study. Besides, although the raw materials for making chalk are cheap, they are not easy to use. We can't let other people's children do it for us for free."

Although the teachers wanted to use the chalk made by Lin Yin, they were not shameless enough to ask Lin Yin to make it for them for free.

Mr. Zhou himself also wanted to use the chalk made by Lin Yin, so he took the initiative to find Lin Yin and told Lin Yin about the matter.

Lin Yin was happy, thought for a while and said, "Teacher, I actually want to set up a chalk factory in the name of the village to manufacture chalk. In this way, it will not only solve the employment problem, but also improve the living standards of the people."

Teacher Zhou was taken aback when he heard it, and hurriedly said, "Can this work?"

After all, doing business is still not allowed in this day and age, Lin Yin said, "The establishment of a chalk factory in the name of the village is a collective interest, and I think it will be agreed."

Teacher Zhou thought for a while and said, "Well, I will also respond to the principal of our school and ask him to ask for you. If it works, that would be great!"

Lin Yin nodded with a smile, "Okay, please trouble Teacher Zhou."

Teacher Zhou said with a smile: "I also have selfish intentions. It would be great if teachers could use such chalk."
