Li Yanjun saw that Lin Yin was still lying on the bed, and hurriedly said, "Lin Yin, get up quickly, we are going to the playground to gather and run, don't be late." ”

Lin Yin slept too late last night, she was too sleepy, but she couldn't help it, she still got up hard, folded the quilt, and after getting out of bed, she quickly washed her face, brushed her teeth, and followed the students in the dormitory to the playground.

There are already a lot of students gathered on the playground, each class has its own fixed position, Lin Yin followed the students in the dormitory to the location where their class gathered, many students have already arrived, Lin Yin is the shortest, naturally he has to stand in the first row, and then Lin Yin saw that their homeroom teacher, Teacher Zhou, also came.

Teacher Zhou began to check the number of people with a serious face, and after making sure that all the students in the class had arrived, Teacher Zhou smiled and nodded.

After a while, the students started running, and the footsteps of "popping" did not stop.

It is said that it is a playground, but in fact, it is far from the playground of later generations, there is neither a rubber track, nor a grass, only a bare land, and when students run, they raise smoke and dust in the sky.

Lin Yin felt a little loveless, too choking, but the other students were used to it, after running five laps, Lin Yin was already tired and sweating, panting, and then everyone stopped, left the playground together, returned to their respective classrooms, and began to study in the morning.

Lin Yin returned to the classroom, picked up the paper, and blew her nose, which was full of black dust, and Lin Yin almost vomited from nausea.

Mourning for his future fate, Lin Yin threw away the paper, took out the textbook, read it again, he knew these things, and fell asleep after looking at Lin Yin.

I slept too late last night, and she was young, I don't know how long she slept, Lin Yin only felt that someone was pushing her, and when she opened her eyes, she saw Teacher Zhou with a serious face, Lin Yin was frightened, and suddenly became energetic.

Teacher Zhou leaned close to Lin Yin's ear and said, "Lin Yin, it's morning self-study time, and I can't sleep." ”

Lin Yin nodded in understanding.

Teacher Zhou asked again, "Didn't you sleep well last night?" Or is it too early to wake up today? ”

Lin Yin is too young, younger than Teacher Zhou's children, and Teacher Zhou will unconsciously care more about Lin Yin.

Lin Yin sighed and said to Teacher Zhou, "Teacher, there are too many mosquitoes in the dormitory, and I can't sleep at night." ”

Teacher Zhou nodded suddenly, and then asked Lin Yin to start reciting the book, and Lin Yin barely attended the class for a morning.

After school at noon, Lin Yin went to the restaurant to buy two steamed buns, and hurried back to the dormitory after a dish, after eating, she went to bed and began to sleep, she was so sleepy, and the noise of the students coming back in the dormitory did not wake her up.

At the end of the evening, Mr. Zhou came to the classroom with a cardboard box, Mr. Zhou stood on the podium, looked at the curious eyes of many students in the audience, and said with a smile, "I listened to the reaction of the students, there are more mosquitoes in the dormitory, so I went to buy some mosquito coils, which will be distributed to everyone, and when everyone goes back at night, they will light it and smoke the mosquitoes to death, so that everyone can sleep well." ”

The students in this class were very moved, these mosquito coils were bought by Mr. Zhou himself, although they were not valuable, but it was enough to show that Mr. Zhou was a responsible and good teacher.

Teacher Zhou asked the class cadres to take the dormitory as a unit, and each dormitory was divided into 20 mosquito coils, and Lin Yin was also very grateful to Teacher Zhou in her heart, and felt that she would definitely be able to sleep well tonight.

After returning to the dormitory, Li Yanjun lit the mosquito coil, and then the fragrance of wormwood wafted out, but what Lin Yin didn't expect was that the wormwood smell of this mosquito coil was so strong that it could smoke mosquitoes to death, but this smoke was too strong, not only could smoke mosquitoes, but also smoked Lin Yin enough, but Lin Yin felt that something was better than nothing.

She still remembers waking up this morning with red bumps on her arms, feet, and legs, all bitten by mosquitoes, and mosquitoes can also spread germs, which is terrifying.

Lin Yin took the washbasin, went down to wash clothes, washed his face and feet.

After coming back, the dormitory was almost out of the lights, and the whole dormitory was filled with the smell of wormwood, and the smoke was so thick that Lin Yin's tears were smoked.

Lin Yin didn't know where Mr. Zhou bought the mosquito coils, the smell was too much, Lin Yin was the kind of person who had a little smell, she couldn't sleep, lying on the bed, although she felt that there were no mosquitoes, but she still couldn't sleep.

It just so happened that the story of the Legend of the Condor Heroes told by Lin Yin yesterday was too attractive, and the girls in the dormitory had been waiting for a long time today, seeing that Lin Yin had gone to bed, Zhu Ningning took the lead and couldn't help but say, "Lin Yin, don't sleep, tell the story quickly." ”

"That's right, Lin Yin, the story you told is so good, I've been thinking about it for a day today."

Lin Yin couldn't sleep anyway, so he continued to tell them the story of the Legend of the Condor Heroes, and when they got to the house, there was no smell, and it was not early, Lin Yin said to everyone, "Okay, it's late, it's time to sleep, and continue tomorrow." ”

After a day's class today, several girls were also tired, and they didn't refute it.

There were no mosquitoes in the house, and everyone slept soundly tonight, but after Lin Yin fell asleep, he always felt a smoky smell of wormwood around his nose, and he still didn't sleep very well.

After two days like this, before going to bed that night, everyone was just about to ask Lin Yin to tell them a story, but they didn't expect the door of their dormitory to be pushed open, and it was a classmate who came, Zhu Ningning saw it, and said to everyone, "They are also here to listen to the story, today I told them the story that Lin Yin told me, and they all liked it very much." ”

The corners of Lin Yin's mouth twitched, yes, she has become a storyteller, but since people are here, she can't blow people away, as long as these people don't make noise, Lin Yin will continue to tell them, it's almost done, and everyone starts to sleep at midnight.

After the other dormitory people left, Lin Yin lay on the bed, smelling the wormwood smoke in the dormitory, and felt that he had to do something, this day was too difficult.

Although when she was in the countryside, every day before going to bed, Zhao Yanan would smoke the house with wormwood to avoid mosquitoes, but when she slept, the smell of wormwood had already been deleted, and the mosquito coil that Mr. Zhou bought was too full of wormwood, and I don't know what was added to it, the mosquitoes were indeed smoked to death, but Lin Yin couldn't sleep.

Lin Yin couldn't help but think of a video of making mosquito coils uploaded on the Internet occasionally in her previous life.

The mosquito coils made by Lin Yin are not native mosquito coils, but are close to the tasteless mosquito coils sold in later generations.

It's not difficult to make this mosquito coil, as long as the things are complete, Lin Yin feels that he should be able to make it.

To make mosquito coils, you need a little chemical raw material: phenylethanol, and I don't know if there is a chemistry lab in this school? Even Lin Yin didn't know if there was a chemistry lab in this school?

On this day, after Teacher Zhou finished class, he was about to leave, when Lin Yin suddenly ran to Teacher Zhou, "Hello teacher! ”

When Teacher Zhou saw Lin Yin, the serious expression on his face softened, and asked, "Is there something wrong with Lin?" ”

Lin Yin looked at Teacher Zhou and asked, "Teacher Zhou, do we have a chemistry laboratory in our school?" ”

Teacher Zhou looked at Lin Yin in surprise, and then said, "Yes, there is, but there is actually nothing in it, although we have a chemistry course, we have never done experiments." ”

Lin Yin said a little embarrassed: "Teacher, I want to try to make mosquito coils by myself." ”

"What?" Teacher Zhou's face was solemn: "Student Lin, your most important task now is to study, what mosquito coils to do?" ”

Seeing that Teacher Zhou was a little unhappy, Lin Yin was not afraid, but argued with reason: "Now I have learned all the knowledge taught by the teacher in class, and I make mosquito coils, which is also a combination of reality and knowledge, which can stimulate my desire and interest in knowledge to a greater extent..."

Teacher Zhou looked at the girl standing in front of him in surprise, and said after a while: "You said: You know what the teacher is talking about now?" ”

Faced with Teacher Zhou's questioning, Lin Yin solemnly nodded, "Yes." ”

"You come with me!"

Lin Yin followed Teacher Zhou and came to Teacher Zhou's office, Teacher Zhou opened the drawer, took out a roll directly from it, put it on the table, and said to Lin Yin: "If you can get a full score in this paper, I will help you!" ”

Exam, Lin Yin is not scared at all.
