At noon, when Lin Yin came back from eating in the restaurant, she saw that several girls had already slept in bed, and two others had gone to other dormitories, so Lin Yin felt that it was better to say hello at night. When he returned to the dormitory after school in the evening, Lin Yin lay on the bed after washing.

When everyone returned to the dormitory together, everyone sat there and waited for Lin Yin to start telling the story.

Lin Yin sat on the bed, it was very dark in the dormitory, and she could hardly see her expression, but she could still hear a little joy from her brisk tone, and only heard Lin Yin speak, "You must have not forgotten yesterday's bet, right?"

Everyone didn't speak, and Lin Yin continued, "Did everyone sleep well last night?" Do you hear the buzzing of mosquitoes? ”

After all, these little girls are still young, most of them are pure-hearted, and if they lose the bet, they are just washing Lin Yin's clothes for a month, these little girls work at home all the year round, which is not difficult for them at all, everyone said, "Lin Yin, the mosquito coil you made is really easy to use, I slept well last night." ”

"Lin Yin, I really didn't hear the mosquito cry when I went to bed last night, the mosquito coil you made is really good, I admit defeat."

"I throw in the towel."

………

In the bedroom, except for Zhu Ningning, they all felt that the mosquito coils made by Lin Yin were better than the native mosquito coils, although Zhu Ningning was holding her breath in her heart, she still nodded and said, "I lost, I will wash your clothes for a month." ”

Lin Yin said with satisfaction, "Then thank you very much." ”

Then Lin Yin began to continue to tell them stories, but tonight Lin Yin's storytelling time was shortened by half, and Lin Yin began to yawn, "That's all for today, I'm a little sleepy, let's go back to sleep." ”

Now that there are no mosquitoes, Lin Yin plans to go to bed early, and everyone doesn't want to go back.

"Lin Yin, I've only been talking about it for a while today, can you talk a little more?"

"yes, Lin Yin, we haven't heard enough yet."

Lin Yin was not used to them, and said directly, "But I'm sleepy." ”

Seeing that Lin Yin couldn't be persuaded by everyone, they had to reluctantly leave Lin Yin's dormitory and go back to their dormitory to sleep.

Lin Yin lay on the bed, smelling the smell of mosquitoes in the bedroom, and slowly fell asleep.

Teacher Zhou is still very concerned about this matter, the first class yesterday morning was Teacher Zhou's class, and Teacher Zhou came to the classroom in advance.

On the way back from the cafeteria, Lin Yin saw Teacher Zhou standing at the door of the classroom, and Lin Yin immediately greeted Teacher Zhou politely, "Hello teacher!" ”

Teacher Zhou was also very happy to see Lin Yin, and then asked Lin Yin with a smile, "Classmate Lin, how is the effect of mosquito coils?" Did you try it? ”

Lin Yin smiled and nodded, "Thank you for your concern, I've tried it, and the effect is very good, it's better than the mosquito coil, and the taste is very light." ”

Teacher Zhou was very happy, "That's great, so that you can get a good night's sleep." ”

Lin Yin originally wanted to find a way to do business for his family, making mosquito coils is actually quite good, especially in summer, the demand is still quite large, but to make this kind of mosquito coil with good taste but good effect, you need some chemical raw materials, in this world, it is not a simple thing to want a large number of chemical raw materials.

It's September now, and Lin Yin made a lot of mosquito coils last time, which was enough to last until October, and by October, the mosquitoes were slowly decreasing.

Teacher Zhou held the chalk head in class, kept writing on the blackboard, and from time to time he would hear a cracking sound, the chalk used in the school, the chalk foam is particularly much, not to mention, and the chalk is also easy to break.

Especially when the teacher erased the blackboard with the blackboard and continued to write, it was the most painful time for Lin Yin.

Lin Yin is not good at covering her mouth and nose in front of the teacher, after all, she is the first row, no matter what the action is, the teacher can see it clearly, but the chalk end in the sky is coming, which makes Lin Yin really uncomfortable.

After the first class, the blackboard was full of words written by Mr. Zhou, and the next class was not a math class.

Lin Yin couldn't wait to run back, and saw the student on duty holding the blackboard eraser, wiping the blackboard hard, and when she came back again, a layer of chalk had fallen on her desk.

Lin Yin frowned, picked up a rag, and wiped his desk clean, but he was thinking in his heart about how to reduce the chalk dust.

Immediately after Lin Yin's eyes lit up, he still remembered that in his last life, a certain island country had a particularly popular chalk, called Feather Brand Powder, the price was much more expensive than ordinary chalk, especially popular with some international mathematics professors, when he heard that this powder was going to be discontinued, many old professors immediately spent a lot of money to stock up on this powder, Lin Yin heard about it in his last life, bought a few boxes, played with it, and found that it was indeed much better than ordinary chalk, writing smoothly, handwriting is clear, and there is not much chalk foam.

Lin Yin wanted to make chalk, but he didn't know the recipe for making this chalk, which could stand out from the crowd and must have its own uniqueness.

She wanted to make this chalk aimlessly, I am afraid it is not easy, at this moment, the voice of the system sounded in her head at the right time.

"Host 3838438, it is the responsibility of the system to remind you that as long as you spend the appropriate number of points, you can redeem all the recipes you want from the system."

Lin Yin's expression was indescribable, this system should have mind reading skills, but this system was in her mind, what was she thinking about in her mind, the system was afraid that she would know, Lin Yin was a little unhappy, but this system was mysterious, she really had no choice but to hold the system for the time being, so she had to ask, "Is there a feather brand chalk formula?" ”

The system said in a sly tone, "Yes, and it only takes 5 points." ”

Lin Yin grinded his teeth, thinking that the sound of this system was so bad, thinking that the system said that the formula of this powder cake needed 5 points, Lin Yin had a toothache, "5 points, this is too much." ”

She worked hard to increase her beauty value to 42 points, and officially stepped into the ranks of ordinary people, her current face, although it can't be said to be beautiful, but it is definitely not ugly, but if it is minus 5 points?

Lin Yin was a little distressed and reluctant.

So Lin Yin asked, "If I make this chalk, how many points can I get?" ”

The system quickly replied, "Because the formula of this foundation is provided by the system, if the host can make it, the system will reward the host with one point, and if the host can rely on their own ability to make chalk, the system will reward the host with five points." ”

Lin Yin asked again, "Is there a book system for making chalk?" If I want to see it, how many points do I need to spend? ”

The system replied, "No points are required." ”

Lin Yin breathed a sigh of relief and said happily, "I want to make chalk materials." ”

The system said yes.

Lin Yin's consciousness entered the system space, and then he saw all kinds of materials for making chalk in the system.

Lin Yin basically knew what the teacher taught, and it didn't sound interesting, so Lin Yin began to look through all kinds of materials for making chalk, thinking if he could make that kind of feather brand foundation.

In fact, making chalk is very simple, and the raw materials are not difficult to find, just tomorrow is Saturday, they can go home for a day off and rest for a day, Lin Yin plans to use this day to make dust-free chalk.

As long as she thought that if she could make dust-free chalk, then she would get 5 points, and she drank and was excited.

After Lin Yin finished reading the information about chalk making, she took out a pen and paper and began to write various chemical formulas in the notebook, and even when she told the story at night, Lin Yin only talked for a while, and then let everyone disperse, and she devoted herself to how to make dust-free chalk.

As soon as class ended at noon the next day, the teacher announced that he would have a day off, and he would report to the school tomorrow afternoon, and the day after tomorrow he would officially start classes.

Lin Yin, who had been holding back in school for two weeks, was already a little impatient, and so were the other students.

As soon as the school announced the end of school, Lin Yin left the classroom with other students, and some students went back to the dormitory first, carrying a big package in their hands, which contained a pile of dirty clothes, which was more favored at home, and wanted to take it home for their parents to wash, but most of the students went home with their schoolbags.

Lin Yin's clothes and socks were washed with help, so Lin Yin went out of the school with a small schoolbag and saw Lin Aimin outside the gate.

Lin Aimin was looking around anxiously, and suddenly saw the girl at the school gate, excited, striding towards Lin Yin, smiling innocently, "Nan, you can figure it out, let's go home quickly, your mother made you delicious food, and your three brothers miss you too." ”

Lin Aimin took his daughter's hand and walked out.

When Lin Yin heard Lin Aimin's words, she also smiled and responded, "I miss my brother too." ”

Halfway through, Lin Aimin leaned down and said to Lin Yin, "Girl, come, Dad carries you, so you can walk faster." ”

Lin Yin took a step back and said with some distress, "Dad doesn't need it, I can go by myself." ”

Their home is too far away from the county seat, if Lin Aimin is allowed to carry her back, Lin Aimin will definitely be tired, she is 9 years old this year, she has eaten well and dressed well this year, and Lin Yin has grown a lot taller.

Lin Aimin knew that his daughter felt sorry for him, and he was even more moved in his heart, and said with a smile, "It's okay, I have a lot of strength." As he spoke, he picked up Lin Yin and strode home.

More than two hours later, Lin Aimin and Lin Yin went home, no one at home, Lin Aimin said, "Your mother is working in the field, your three brothers haven't finished school yet, you can play at home for a while." ”

Lin Aimin and Lin Yin didn't eat at noon, Zhao Yanan had already left them food in the kitchen, and fried two dishes, one was scrambled eggs with tomatoes, and the other was fried bacon with garlic sprouts.

Lin Yin was surprised, "Dad, why do we still have bacon in our house?" ”

Lin Aimin smiled and said, "You gave it to your grandmother when she came a few days ago." ”

Lin Yin nodded, indicating that he understood.

After eating, Lin Aimin was about to work in the field, Lin Yin nodded with a smile, and watched Lin Aimin go out.

In the afternoon, Zhao Yanan came back early, after seeing Lin Yin, Zhao Yanan was very happy, but he complained in his mouth, "Your father is also careless, I told him, when you come back, let him take out the chicken cake at home for you to eat, but he didn't take it out." ”

As he spoke, Zhao Yanan stepped forward and took out a few pieces of chicken cake from the cabinet and handed them to Lin Yin, and said with concern, "Are you hungry?" Eat quickly. ”

Although the chicken cake is not as delicious as the desserts of later generations, in this era, smelling the sweet smell of the chicken cake, Lin Yin has unconsciously secreted saliva in his mouth, but Lin Yin only took one bite and did not move the rest.

Zhao Yanan said, "These pieces are all reserved for you, eat them all." ”

Lin Yin said, "Keep these pieces for my brother." ”

Then he took out another piece, handed it to Zhao Yanan's mouth and said, "Mom, you eat it too." ”

Zhao Yanan was immediately moved, "My family is really sensible, my mother doesn't like to eat this, you can eat it yourself." ”

There are not many chicken cakes, and Zhao Yanan is reluctant to eat them at all.

Immediately after that, the three brothers Lin Changping came back, and the three brothers jumped another level this year, after all, with Lin Yin giving them make-up lessons, the three brothers made progress quite quickly.

In this era, there is no TV and mobile phone, and the three brothers also know how to study, they catch up with each other on weekdays, supervise each other, and make rapid progress in learning, especially with a genius sister pressing on it, and the three brothers don't want to be too far behind Lin Yin. Seeing that Lin Yin was back, the three brothers were very happy, and Lin Changping talked a little more, "Wuya, how are you at school?" Has anyone bullied you? ”

After Lin Changping said this, Lin Changan and Lin Changqing both looked at Lin Yin.

Lin Yin hurriedly shook his head and said with a smile, "Don't worry, no one bullied me, I'm doing well in school." ”

Lin Changping nodded, but Lin Changan stared at Lin Yin and said, "Wuya, I look at you as if you have lost some weight, isn't the food in the school delicious?" ”

Lin Yin told the three brothers about the previous incident.

Lin Changqing's eyes lit up and said, "Wuya, you are so powerful, you can even make mosquito coils?" ”

Lin Yin couldn't help but grin herself, and then said, "I still want to make powder." ”

Lin Yin said to her three elder brothers, "I sit in the first row, the teacher has to write a lot of words in every class, and every time I wipe the blackboard, I feel very uncomfortable, and I want to make a dust-free chalk." ”

Lin Changping was surprised, "Is there still dust-free chalk?" ”

Lin Yin nodded, "I can't say it's completely dust-free, but it's much better than the current chalk, and I need you to help me." ”

The three elder brothers immediately patted their chests and promised that they would do their best to help Lin Yin.
