At the beginning of August in Yangcheng, summer has just begun.

Xia Yu was riding a bicycle, his white T-shirt was wet, and the beads of sweat on his face occasionally dripped and smashed on the asphalt in a row. I really regret not bringing a hat with me.

Zhang Tianhe hid in the shade of a tree and waited for him, and he didn't see where the cool was, and when he saw Xia Yu coming from afar, he shouted: "It's too hot this day, go to the ice bar to escape the heat first!"

Today is the day before the start of school, and it is required to arrive at school by 2 p.m., and you must be there in person. The class assignment notice has already been issued, and the main reason for coming here today is to get some information, get to know the teacher, and of course, pay some money.

Xia Yu ignored him and said, "Anyway, these clothes are wet, let's go straight to school." ”

Zhang Tianhe muttered: "Okay, I don't know if you can lose weight by sweating......"

The two continued to ride to the school in the sun, and it was half past one when they arrived at the school gate.

An Audi A4 stopped on the other side of the road twenty meters away from the school gate, Qi Fei jumped down from it with sunglasses on, and shouted at the two from a distance: "Xia Yu, fat man, wait for me!"

Zhang Tianhe teased him and said: "Hey, Feishao, you get out of the air-conditioned car and shout hot to us!"

Qi Fei shouted loudly: "Please, I'm afraid of being late, I heard that our new head teacher is ruthless!"

Xia Yu thought of his homeroom teacher, Boss Fei, and his heart was also cold, and he said: "It seems that Boss Fei of our class is even more dominant, and it is estimated that he will be punished if he is one minute late...... Let's hurry!"

Boss Fei's original name was Fei Jiangsheng, and he was Xia Yu's new head teacher in the third (first) class of high school, and he was also named Yan in No. 1 Middle School, but it is said that he was also assigned to whom. He had just been sent to the key class of the third year of high school, and it should have been the turn of the first year of high school, but I don't know why he continued to teach them.

Zhang Tianhe muttered: "Obviously there is still half an hour!"

Qi Fei also said: "Xia Yu is right, it's better to be early than late, damn it!"

The two have been at the same table for a year, Zhang Tianhe knows that this kid should be the son of a high-ranking official, but he doesn't have that kind of superior spirit, Xia Yu's evaluation of this is "good tutoring".

At this time, the school was full of senior high school students, and they walked to Building No. 5 in twos and threes, which was the unified teaching building for senior high school.

Fortunately, No. 1 Middle School is also an old school, and there are lush banyan trees planted on the side of the main road, which makes people feel a lot more comfortable in the shade along the way.

Downstairs in Building No. 5, a big list was still posted on the bulletin board outside, on which was the class information that had been announced. Some people who didn't ask before or couldn't remember clearly looked around the list.

"By the way, Qi Fei, what class are you in?" Xia Yu asked.

"Class six, fortunately it's the first floor. I don't think it's too late to get out of school today, so I'll play some ball?"

"It depends, we don't live in two shifts. ”

"Done. ”

I found a place to sit down casually, and there were not many acquaintances, of course, it was for Zhang Tianhe. Xia Yu can still vaguely remember most of the people in the class, but many people have a vague impression.

At two o'clock in three minutes, a middle-aged man entered the classroom, and some acquaintances couldn't help but whisper, "Boss Fei is here."

The noisy teacher suddenly fell silent.

From the outside, Fei Jiangsheng doesn't seem to be as fierce as he imagined, he is not tall in his early forties, slightly bald, and his Mandarin is not very good, and he speaks with a straight eye.

Just looking at it, no one would have thought that he was teaching English, or a top special teacher in No. 1 High School.

But Xia Yu knew that this little old man would become a nightmare for many people in the future. No one can stand an old-fashioned and strict sù who will tell you a big truth every day. There was once a son of the deputy district chief who was educated by him for more than two hours after making a mistake, and finally couldn't help but admit his mistake again and again and make a guarantee.

And it is rumored that Boss Fei's family has a brother who is also an official! Well, this legend Xia Yu has been in his class for a year in his previous life, but he has not been able to confirm it. The main thing is that he is not interested in these at all.

In fact, from Xia Yu's current point of view, Boss Fei is definitely conscientious among the teachers, working for more than ten hours a day as a class teacher, and often looking for people to chat and talk, but it is a little stereotyped.

Well, maybe not at all, it's already past two o'clock at this time, and the three classmates who came late have already been called by him to stand at the door.

"On the first day of school, I reported before two o'clock last time, do you know, the whole class is waiting for you! How precious the time of the third year of high school is, you will all experience it in the future! Don't think that you can sit back and relax when you enter the key class, there is still a line in my key class last year! Do you know no!"

The three of them nodded busily, and the classmates in the teacher were stunned.

Because the table had not yet been divided, Zhang Tianhe and Xia Yu sat together, and he leaned over and whispered: "It is said that Boss Fei's verbal conversation is 'do you know', known as the top five most popular slogans!"

Xia Yu subconsciously just wanted to remind him, but suddenly Fei Jiangsheng's voice came-"The two who are talking about small words, let me stand at the door! Do you know no, I am most annoyed by the small talk below, and I can't stand up and say anything!"

Of course I know, isn't it that I haven't had time to remind him? Zhang Tianhe, this kid is naturally chattering, and I don't know how many times he was taught a lesson by Boss Fei in the next year.

After standing for about ten minutes under the sympathetic gaze of the whole class, the five finally received amnesty and returned to their seats.

Although No. 1 Middle School is known as "Su zhì education", after all, it is the third year of high school, and there are more than a dozen new textbooks and various materials, which fill the schoolbag.

The next step is to introduce a lot of questions, including the teachers of each subject, the materials to prepare, and who to call if you have any questions...... Then there's self-introduction.

The grades in the key classes are excellent, but there are all kinds of other aspects, and there is a very beautiful girl who is stammering, which surprises everyone.

Well, this girl named Zhao Lulu seems to have cured her stutter before graduation? Xia Yu can't remember it clearly.

For him, this memory is real, but because it is too long ago and not very important, some things are not very clear.

In fact, he was constantly thinking about a question.

I can be reborn, so is there a similar situation in this world, history, and even now?

In addition, I have made a lot of changes in some things through hard work, such as a series of things caused by my father's professor's evaluation, such as Polestar, a company that did not exist before......

Xia Yu remembered many stories of parallel spaces in science fiction novels, and specifically checked on the Internet and found that Hawking also had an explanation for this.

His explanation is that when the time traveler goes back in time and changes history, the timeline becomes divided, and the divided timeline unfolds another history. At the same time, in order not to destroy the law of cause and effect, the theory of parallel space can be established - every changing history is a parallel space of a series, so that the grandmother paradox can be explained.

However, this idea is basically based on the quantum physics framework of Planck's constant, which is difficult to demonstrate......

"Brother Yu, it's your turn!"

Returning to the classroom for a while, Xia Yu, who fell into his own thinking world, was woken up by Zhang Tianhe, and was slightly stunned and knew that it was time for him to introduce himself, so he stood up hurriedly and said unhurriedly: "Hello everyone, my name is Xia Yu, Xia of Summer, Yu of the universe, I like to play ball, listen to music and tinker with things, I hope to get along with everyone in the next year." ”

The name was given by my grandfather, who was still alive at the time. His parents and grandfather were in the countryside when he was born, and it was the summer when the sky was full of stars, so he fell into this name.

He liked the name very much, and he also liked the word "star".

There was a sparse applause that remembered that it was already halfway through at this time, and everyone's applause was not as serious as it was at the beginning.

Zhang Tianhe's movements were also very refreshing, and he stood up directly and said: "My name is Zhang Tianhe, a famous He, I like to sleep and read novels, well, is it okay to play games?"

The audience laughed, this kid really dared to play treasure in front of Boss Fei!

Some people also recognized him and whispered to the person next to him: "It's him, one of the three people with a perfect score in mathematics at the end of the term, a science genius, it is said that English will not be able to enter the top five of the grade!"

Fei Jiangsheng's face was calm, and he couldn't help but speak.

After the class was introduced, he began to talk about some life-related matters, mainly for the boarding students. Most of the students in No. 1 Middle School are local to Yangcheng, but there are also a small number of students from other places, and Yangcheng also has a county that is a little farther away, so the proportion of students living in the school is about half.

These dormitory students came to report in the morning and arranged the dormitory, plus they have lived in many years and many things are familiar, and they are a little impatient to listen to Boss Fei's nagging at this time, but no one dares to speak, but there are a lot of small actions.

"The first snow of 2002 was ...... than ever"

Suddenly, a piercing piece of music sounded, and the phone's external speaker was really bad!

On the podium, Fei Jiangsheng's face darkened, and he almost shouted: "Who's it, stand up!"

Several people subconsciously looked at a boy behind them, and the boy stood up indifferently on the surface, but his face was somewhat embarrassed.

"What's your name?"

"Didn't you introduce it just now, Duan Feng. ”

Xia Yu was a little familiar when he heard this name, his eyes swept over, and he was suddenly stunned, it was him!

If I remember correctly, this is the male student who was entangled with the Chinese teacher Zhou Wei in Zhang Tianhe's gossip later! But I have the impression that this person has never been in the same class as him at all, could it be that he also changed his class with Zhou Wei because of his rebirth?

"Hand in your phone!"

Duan Feng walked up helplessly, he didn't dare to say anything at this time, this boss Fei's father told him that the family was going to come forward to invite him for a meal.

Fei Jiangsheng saw that he was still honest, so he lost his anger a little, but he still said coldly to the class: "You are not allowed to bring mobile phones and pagers, this is written in the student code, it is not counted today, and it will definitely be a punishment if you find it in the future, do you know it!"

Duan Feng didn't dare to reply, and the whole class was stunned by the sudden outbreak of Boss Fei.

Xia Yu was still trying to recall more things about Zhou Wei and Duan Feng.

It's not that I'm not interested in their business, but mainly curious, if it wasn't for the initiative themselves, such as the founding of Polestar Electronics, what would happen to the world that has changed by the butterfly effect on its own?

Or as long as he doesn't take the initiative to intervene, there will be no fundamental impact? For example, for Duan Feng, maybe in the third class and the first class, in fact, there is not much difference......

Xia Yu thought about it boredly for a while, until it was finally over and he could leave.

This was still not a ball in the evening, because at the end of almost five o'clock, Xia Yu secretly turned on the machine and received a text message from Song Xiaogang.

This kid has been a little worried about having nothing to do recently, so he asked Xia Yu to arrange things for him.

He didn't find something suitable for him to do, and then he was a little embarrassed to get a high salary? Thinking of some ideas in Polaris' next-generation products, Xia Yu decided to talk to him.
