The entrance of the 12th Middle School.

"I'll go in, I'll see you later. ”

After parking the car, Lin Wu waved to Pei Jianing in the car, closed the car door and entered the school.

It's not the first time Lin Wu has helped his dad substitute, after all, he is a student from the Normal University, and it is not difficult to teach a group of high school students occasionally.

However, there are not many students on the campus of No. 12 Middle School today.

After all, it's already a holiday, and only the sophomore students who are struggling to enter the third year of high school are about to enter the third year of high school and have a year to meet the college entrance examination, so the school will add classes.

Many years ago, Lin Wu was also a student of this middle school, so he was naturally familiar with the campus environment.

First go to my father's office, the office of the teaching and research department on the third floor, and most of the teachers here are the homeroom teachers of each class in the second year of high school.

The office is relatively empty, there are desks in each compartment, and there are automatic water dispensers and air conditioners on the side, and there are few people, and it is estimated that most of them have gone to class.

Lin Wu walked to his father's desk, and a nearby teacher looked up at him, and couldn't help laughing, "Isn't this Lin Wu?"

"Hello Mr. Xu. Lin Wu nodded politely, although he hadn't taught him, he had a good relationship with his father.

Teacher Xu took the teacup, took a sip, looked at the time again, and said, "The first class is almost over, you should hurry up and prepare, has your father given you a lesson plan?"

"Given, I'll see. ”

Lin Wu nodded slightly, flipped out the lesson plan and glanced at it, and couldn't help but feel a little big.

Damn, do you want to warm up the knowledge of the third year of high school in advance?

The knowledge of chemistry has long been returned to my father, but I remember that A and B can be converted into each other, B can produce C in boiling water, C is oxidized into D in the air, D has a low concentration of hydrogen sulfide smell, so calculated, A is a chicken, B is an egg, C is a cooked egg, D is a rotten egg.

I've forgotten all the chemical reaction equations, so don't mistake people.

Brush.

Lin Wu closed the lesson plan, threw it on the table, and then flipped through it on his father's desk, his eyes couldn't help but light up, and he turned out a large pile of mock test papers at the end of the second year of high school.

flipped through it again, and happily found a pile of chemistry test papers for the new sophomore high school standard.

"Good stuff. ”

Lin Wu couldn't help but sit down happily, and suddenly felt more relaxed.

Yes, it's much easier now, one class in the morning and one class in the afternoon, just let this group of students do two sets of questions.

By the way, tonight's homework will also be assigned two test papers, a good holiday, anyway, I have nothing to do.

Lin Wu sorted out the test papers with a smile on his face, and when he was in class later, he sent the papers down, he just had to be the invigilator, and he also played with his mobile phone.

Teacher Xu next to him seemed to have discovered Lin Wu's intentions, and couldn't help but be speechless: "Lin Wu, shouldn't you just let those students do the questions?"

"That's right. ”

Lin Wu nodded, and said, "No matter how much you talk about the lectures, it's not as practical as doing a few sets of questions, by the way, did my dad assign summer homework?"

"Makes sense...... Teacher Xu tugged at the corners of his mouth, knowing that this kid was lazy, coughed and said, "Your dad has already assigned summer homework, so you don't have to worry about this......

"Oh, that's a pity, I remember when I was in the summer of my sophomore year of high school, my dad asked me to do two sets of questions, a total of more than 60 papers, and it was just right for summer homework. Lin Wu sighed regretfully.

“......”

Teacher Xu was speechless, you kid is here to take revenge on society, right?

In a moment, the bell rang for the end of class.

Lin Wu poured a glass of water, sat on the office chair, played with his mobile phone, and waited for the preparation bell to ring before entering the classroom.

After a while, a girl in a school uniform with a ponytail walked in from outside the office, came to Lin Wu's desk, couldn't help but be slightly stunned, and asked, "Where is Teacher Lin?"

Lin Wu turned his head to look, looked at it, and couldn't help but smile: "It's you, you've grown up, I remember that you are the representative of the chemistry class, right?"

"Senior brother?"

The ponytail girl was stunned, and she also recognized Lin Wu, after all, it was not the first time that Lin Wu had substitute taught.

"My dad has something, and I substitute teach. Lin Wu put a stack of test papers on the desk on the table and said, "You count the papers, send them out when you go to class later, and do the questions in the next class." ”

"......" the ponytail girl sighed, obediently counting the rolls.

Lin Wu took a sip of water and suddenly asked, "By the way, is there a student named Pei Jianing in the class?"

The ponytail girl was slightly stunned, "Yes, but she seems to have transferred to another school, and she hasn't come to school for a month." ”

I don't know if Pei Jianing died in a car accident?

Lin Wu had a faint guess in his heart, it seemed that Pei Jianing didn't have any friends before his death, otherwise he wouldn't have died and no one would know.

"I remember when I came to substitute teach at the beginning of last year, I didn't seem to have seen her. Lin Wu wondered.

His memory is still good, especially a good-looking little beauty like Pei Jianing, with long black double ponytails, relatively large eyes, and two small tiger teeth, which is quite distinctive.

If he had seen her before, he couldn't have been impressed.

"Well, Pei Jianing turned around when he was a sophomore in high school. The ponytail girl nodded, "Maybe I've also turned away now, I asked Zhang Yuqing last time, but she said she didn't know." ”

"Zhang Yuqing?" Lin Wu didn't know the names of these students.

"That's right, she and Pei Jianing are the closest, and they often go to and from school together, so they seem to be Pei Jianing's only friend in the class. The ponytail girl said.

The only friend?

Lin Wu's heart moved, and he couldn't help asking: "Is Pei Jianing's popularity very bad?

"This ......"

The ponytail girl seemed to be a little unsure of what to say, and said a little helplessly: "She seems to be an orphan, with a cold personality, rarely communicates with others, except for boys, other girls basically don't like her......"

"Is it because she's pretty?" Lin Wu couldn't help laughing, these little kids.

"No...... ponytail girl hesitated, but still said, "The main thing is that her character is not very good." ”

Lin Wu glanced at her, "Conduct?"

"Well, she stole something from her classmates. The ponytail nodded.

"She steals?" Lin Wu frowned slightly, he didn't think Pei Jianing would do that kind of thing.

The ponytail girl whispered: "Yes, she stole Xia Bing's mobile phone last time, she didn't admit it, and the other boys didn't believe it, but finally it turned out in her schoolbag." ”

Xia Bing...... Ice?"

Lin Wu's eyes changed, and Pei Jianing said that she 'killed...... Bing', it should be a person with 'ice' in his name, so it seems that it could be this Xia Bing?

"Which one is Xia Bing?" Lin Wulian asked.

"Senior brother, you should remember, Xia Bing is very beautiful, very tall, with a little dark skin, before Pei Jianing came, she should be the most beautiful girl in our class. The ponytail girl said.

Even a girl is willing to admit that another girl is beautiful, and it seems that her appearance should not be low.

Lin Wu recalled carefully, and he did have the impression that there was such a beautiful little girl, who was almost the same height as him, and her skin was a little dark.

"It turns out that she is Xia Bing. Lin Wu nodded slightly, and asked again, "Is her relationship with Pei Jianing very bad?"

"Hmm......" The ponytail girl nodded silently, and said with a low face: "Moreover, Xia Bing is dead, she accidentally fell from the rooftop of the top floor, and her legs were broken, and she was later sent to the hospital for rescue, but she was not saved." ”

Broken leg?

Lin Wu's heart moved, it seems that this Xia Bing is the ice that Pei Jianing said.
