The Weibei Plateau belongs to the southern edge of the Loess Plateau, the northern slope of the Guanzhong Plain, and is sandwiched by the Loess Plateau and the Guanzhong Plain.

Xun County is one of the five counties in Weibei, which belongs to the northernmost county, which is close to the border of Gansu.

"Bang" is a very dull sound!

It was very loud in this silent night! It took half an hour before a dark shadow flashed out of the corner, poked his head out of the staircase, and listened closely.

Squatting in the corner of the wall for half an hour, he still didn't seem to be at ease, and after waiting at the top of the stairs for another half hour, the black shadow turned back to the place where the sound was made just now.

The place where the black shadow is located is the northeast corner of the third floor of a teaching building in the town middle school, and the classroom with the smashed windows is the library of the town middle school.

Heiying's name is Liu Shisan, and he is an eighth-grade student at the town's middle school, and he likes to read extracurricular books since elementary school, and his academic performance is quite average.

By chance, he heard the news that there were a lot of extracurricular books in the school library, and he kept thinking about how to get them.

After the summer vacation, he came to the school when he had nothing to do, and several people on duty in the school knew exactly when they came out to patrol.

In the past two thousand years, mobile phones have just emerged, and they are still black bumps, let alone any monitoring equipment.

In the first week of the second month of the summer vacation, Liu Shisan's long-planned plan was put into action.

When it was dark, Liu 13 rode an old-fashioned 28-weight bicycle with a snakeskin bag on the back shelf and left the village.

The town middle school where he attended, some way from the village, had a threshing field not far from the back wall of the school, and his bicycle leaned over the straw stack and took down the snakeskin bag.

I picked up two bundles of corn stalks on the side and put them on the bicycle, looked around left and right twice, and then walked towards the school.

There is a circle of poplars around the fence of the backyard of the school, and where these poplars are leaning against the wall, the wall is stepping out of one small pit after another.

This is the most convenient way for boys who are late or want to take a shortcut to enter the school, Liu Shisan can find several wall points around this wall with his eyes closed, and turn over them.

After climbing over the wall is a large playground, this playground is very large, when he was in elementary school, Liu 13 thought that the playground of the primary school was already very large, and the physical education teacher once threw a fake grenade for 50 meters.

That is, he was thrown from one end of the playground to the other, which was an insurmountable distance in Liu Shisan's mind in the last few years of primary school.

And when he was in the first year of junior high school, that is, in the seventh grade, he realized that the playground of this new school was so big that he would be tired and panting after running a lap.

A tiled house next to the wall, the closest to the wall is the dormitory of Liu Shisan's head teacher, where he received his school uniform when he was in the sixth grade.

Ninety-six yuan for a school uniform, this is the largest amount of money Liu Shisan has seen since he went to school, and the tuition fee is only seventy-two yuan, including books, tuition and miscellaneous fees, and two yuan for class fees.

There are three rows of 124 tiled houses between the school building and the playground.

Most of the school's teachers live here, as well as water rooms, sports equipment rooms, etc., and in the house next door to the sports equipment room, there is a teacher who guards the door.

The school is not valuable, but the basketball and football in this sports equipment room are still rare objects for the Weibei Plateau, this remote town.

Therefore, the school is also equipped with full-time supervision during the summer vacation, and of course, it also takes care of other items and facilities of the school part-time.

When Liu Shisan passed by this hospital, he tried to be as careful as possible, because the physical education teacher who guarded this place was very powerful, and he was also a female physical education teacher who lived with her boyfriend.

Someone was once looking for trouble at school, and was knocked down by this female physical education teacher alone, and she was also the first idol that Liu Shisan worshipped.

There are three teaching buildings in total, two entrances, and there are iron gates at the entrance, which is not difficult for Liu Shisan, who is already well-equipped.

Liu 13 pulled the snakeskin bag into a lump and threw it into the corridor on the second floor, and then began to work on the problem of entering the iron gate.

This kind of teaching building belongs to the single body, and the corridor is in the front, which is the common teaching building model.

The iron gate is not the kind of pull-up and down, but the telescopic door that pushes left and right, and above the iron gate on the west side, there are four words that go up every day.

There is one less horizontal iron bar in the fixed place of the upper word, Liu 13 stepped on the block of the sliding door, and then straightened the horizontal bar of the upper word, and then there was no horizontal iron bar square.

Liu Shisan's classroom is on the second floor, this place he has been walking for a year, and he is particularly familiar with this door, this horizontal iron bar has fallen off when the door is installed.

Liu 13 was also present at that time, and kindly reminded the door decorating master, but the master said that he didn't need it, and directly covered it with the words.

This space can only allow a child to drill through, Liu Shisan's family background is not very good, and his body is already thin, so it is just enough to allow Liu Shisan.

On the opposite side of the teaching building, there is a house with people, and the lights are on, and the person living in this house, Liu Shisan, also knows, is from the same village as Liu Shisan, and is a logistics teacher of the school.

The two rows of tiled houses in front of the teaching building are the dormitories of the principal, vice principal, dean of students, grade directors and other leaders.

Liu 13 went directly to the third floor, and the windows of the school were three floors up and down, and the middle floor was particularly high, with three windows in the upper, middle and lower floors.

The lower windows are dead, with no leaves, and the middle and left and right windows can be opened, while the latches of these two windows are at the bottom.

The window is about one meter long, and after exerting force on it, a hole can be opened above, which is enough for Liu Shisan's hand to reach in and open the top window blade.

This method is also the only way to open the teacher when there is no key, and this method is widely spread in schools.

Liu Shisan also tried to open the window of the library in the same way, pulling open the top latch, but pushed the upper window open.

Liu 13 touched the nail, that is, the window was sealed from the inside.

Liu Shisan hid in the shadows, thought about it for a long time, and finally decided to smash it, and smashed it open, because school will start in two days, and the teachers in the school will arrive one after another tomorrow night.

In that case, there will be no chance in the future.

Liu Shisan took out a dagger from his pocket, this is a sheep-killing knife, in junior high school, he has just begun puberty, and beating people and being beaten is commonplace.

If it weren't for this dagger, Liu Shisan didn't know how many times he had been beaten, junior high school was such a youthful period, I don't know why I was beaten, and I didn't know why I was beaten.

Liu 13 lined his school uniform on the glass on the side of the inner wall of the library, gritted his teeth, and then smashed it with the knife handle of the dagger.

The sound of "bang" was particularly loud, and Liu Shisan immediately went to the corner, held his breath, and listened carefully to the movement on the edge of the teaching building on the campus.

The heart that was mentioned couldn't be returned to its position for a long time, until Liu Shisan estimated that it had been half an hour, and there was still no sound of anyone moving or checking.

He stood up, then went back to the first floor, and listened carefully through the iron gate to the campus for a long, long time, until he made sure that no one was there, and then he returned to the third floor.

The broken glass was taken down by Liu Shisan piece by piece, and the windows of the library were nailed with blue curtains, while the ordinary classrooms were made of white paper.

The window was very large, much larger than the small lattice hidden behind the upper word, and the windowsill more than one meter high, Liu Shisan supported it with both hands, and then climbed into the library.

This three-classroom library appeared in front of Liu 13 for the first time, and Liu 13 took out a laser projector, which belongs to infrared.

It's the kind of infrared lamp that I played with when I was a child that irradiated very far, three yuan a piece, three yuan is a lot of money, in the era of five pieces of candy a dime.

For this lamp, Liu Shisan's summer vacation, digging herbs during the day and catching scorpions at night, sold for a total of seventy-four yuan, just enough for his tuition, he took out three yuan to buy this lamp.

The light emitted by this lamp can only be detected when it shines directly into the eye and shines on the object, and it is concentrated into a single beam, which is especially suitable for this kind of occasion.

Liu 13 started from the first row of bookshelves, and Liu 13's goals were novels, history, geography, military, and biographies, all of which were Liu 13's goals.

Liu Shisan found that the books in the library were all big guys weighing several pounds, either Cihai or a series of books, which made him depressed.

On the last two bookshelves, Liu 13 found the target, and according to the name and book introduction, Liu 13 filled a snakeskin bag full of books.

These books could not be obtained from the gap in the iron gate and the lattice behind the upper word, Liu Shisan carried the snakeskin bag to the staircase on the first floor, and took out the stack after stack to release the gap in the iron gate.

Then the snakeskin bag is stuffed out, and then the person goes out again, and then the book is put away.

Liu Shisan didn't know where he got such a lot of strength, he had a snakeskin bag weighing sixty or seventy pounds, so he carried it to the playground.

The whole process took three or four hours, and more time was spent on picking books, mainly because there were too many books, and Liu Shisan, who knew more about books, knew that some books were more valuable than novels.

It's just that Liu Shisan still didn't choose these books, he still chose novels, and there are nearly a hundred of them, what he steals is no longer important to Liu Shisan, the important thing is that he reads good books.
