Jianghai Puxi Senior High School.

This is a high school with a long history, and there are many old trees and pines and cypresses on the sidewalks inside and outside the campus, which shade a large area in the summer.

Li Xiufeng wore a mask and a cap, like a thief, and came to the school gate, and many cars were parked on the parking apron at the entrance of Puxi High School today.

I have to say that Jianghai key high schools like Puxi High School are not only strong in terms of teachers, but also in terms of students, which can be seen from the prices of those "scooters" at the door.

Times have changed, in places like Jianghai.

A poor family can produce a noble son.

However, difficult.

A family that occupies more social resources can easily cultivate a key high school honor student with excellent character and learning.

Li Xiufeng looked at the magnificent school, and couldn't help but think of his high school, only to feel that Jianghai was really not in the same dimension as the school in the big ravine of Sichuan and Chongqing.

After sighing with emotion, Li Xiufeng suddenly made a bitter face again, and unconsciously remembered the call he received from his aunt this morning.

"I'm working overtime on weekends, Xiaofeng, you go and help me hold a parent-teacher conference for Zilu."

"But..."

"It's nothing, you go there and listen to what the teacher has to say, just come back and report to me."

"But aunt..."

"Hey, it's okay, you just said it's her cousin, and the current teacher is very open-minded."

“......”

Facing my aunt who is not on the same channel at all,

Li Xiufeng's sentence "But what if I am recognized" still failed to say it after all.

Of course, in the style of my aunt Liu Jiahui.

If Li Xiufeng really said that, the other party would probably squint and say something like "You really think you are a star".

Question: I'm really a star now.

Li Xiufeng felt that he had to take time to talk to his aunt and said that his current identity was no longer suitable for showing his head in public.

It's not that he's afraid of being recognized and being disturbed, but he's mainly afraid that his appearance will disturb the people, and he may have to post a Weibo to apologize for occupying public resources.

It's uncomfortable!

Standing at the school gate, Li Xiufeng took out his mobile phone and called Xia Zilu.

After asking about the classroom, he rubbed his stomach before he had time to eat breakfast in the morning, and his eyes fell on the roadside stall not far away.

There is an inner taste.

Xia Zilu's high school in front of him, although from the perspective of the row, the high school in his hometown in Li Xiufeng's memory is heaven and earth.

But the street not far from the school gate is similar to the roadside stalls.

This is not the peak time for school and school, there is no one on the street of the stall, Li Xiufeng put his hands in his trouser pockets, and walked over to ask for a pancake fruit.

A minute of effort,

The aunt skillfully spread it out for him.

Li Xiufeng took the hot pancake fruit, subconsciously took off the mask, and grinned and took a bite.

But as soon as he took a bite, he suddenly reacted again, this pedal horse will not be exposed, right?

Li Xiufeng subconsciously lowered his head and pulled down his mask, and looked up at the aunt opposite vigilantly.

Rub rub rub rub!

The aunt was holding two pancake spatulas and cleaning up the remnants on the pancake pan, but her eyes looked at Li Xiufeng with some curiosity.

Sure enough, it was exposed...

Li Xiufeng sighed, he didn't expect that he was so popular now, even the fifty-year-old aunt at the roadside stall at the school gate was familiar with him.

Li Xiufeng coughed dryly, just about to say something.

The aunt smiled evilly, waving a pancake shovel and waving her hand at Li Xiufeng.

"Young man, it's not been a long time since I've been repeating it, right? After eating, don't be discouraged, my aunt has seen it for eight years. ”

？？？

Li Xiufeng was stunned for three seconds when he heard this, and then he came back to his senses a little, feeling that this aunt regarded him as a repeat student of this school...

Jianghai Puxi High School is a key high school, and there are often some students who fail the college entrance examination to find a relationship to enter the "World War II".

Some people who are not Yan Da and Mizuki do not read, and it is common for them to struggle for a few more years.

Aunt is well-informed, Li Xiufeng laughed dryly, and said as he left, "It's okay, next year, no, you won't see me tomorrow." ”

......

Xia Zilu was a sophomore in high school last semester and a junior after the summer vacation, and Li Xiufeng came to hold a parent-teacher meeting at the beginning of the third year of high school.

It is estimated that the school wants to communicate with parents to lay a foundation for communication in the struggle of the last year of high school.

The new semester has just been classified, and Xia Zilu's class is the second class of the third year.

When Li Xiufeng followed the signs in the school to find the class, the classroom was full of a large number of people.

In the front are the students, and in the back are the extra chairs, where the parents of the students are sitting.

On the podium, there was an old man with age spots on his face and a pair of reading glasses of astonishing thickness, but his hair was meticulously groomed, and the whole person looked in good spirits.

Li Xiufeng was wearing a peaked cap and a mask, leaned over the window and looked at it a few times, and found Xia Zilu sitting in the third row in the middle of the class.

Xia Zilu also seemed to notice that there were people outside, but although she usually secretly drew small **, she was a wordless girl at school.

She twisted her head, but she didn't dare speak.

His eyes drifted to the back, as if he wanted to signal Li Xiufeng to sneak in through the back door.

For most people in their school days, walking through the front door in front of the eyes of countless students in the class during class is tantamount to a form of torture.

Li Xiufeng didn't have these concerns, he walked to the front with a big grin and knocked on the door.

When he entered the door, Li Xiufeng took off his hat, but he didn't take off his mask.

"Please come in."

The old man's voice inside was full of anger.

After Li Xiufeng entered the door, he glanced at the other party.

The old man on the podium looked over Li Xiufeng, turned around and continued to write on the blackboard with chalk.

"Go back to your seat and don't be late next time."

Li Xiufeng was a little speechless in his heart, listening to this tone, he felt like a student again.

Am I so young?

There are so many people sitting below at this time, and it is not the time to explain, Li Xiufeng answered, and walked towards the back unhurriedly.

When passing by Xia Zilu in the third row, Li Xiufeng knocked on her desk with his hand knuckles.

I have to say that this move is a bit "violation" in high school, and there are boys in the back row who see this detail, and the surroundings are suddenly "buzzing".

Xia Zilu is a budding magnolia flower in the class, and she never seems to have had any contact with boys in her impression, but this does not affect the admiration of other boys in the class who are just beginning to fall in love with her.

In just a moment, Li Xiufeng felt that his back seemed to be stared at by several eyes.

Xia Zilu, a simple girl, was stunned for two seconds, and suddenly blushed.

When Li Xiufeng walked to the back, he casually found a seat and sat down, and the girl at the same table as Xia Zilu poked her.

"Zilu, is the boy wearing a mask in our class just now? So handsome, hehehe, how do you know him? ”

The girl on the other side glanced back with some confusion and couldn't help but say:

"Wait, but don't you think that boy just walked by... Sound familiar? ”

Xia Zilu didn't speak, looking down at the desktop.

On the podium, the old man seemed to pay attention to the buzz below and the initiators.

He looked at the boy who had randomly pulled a seat in the back of the classroom and sat down, and labeled him a "problem student" in his heart.

The situation of the graduating class is more complicated, it is related to the life of many people, there are so many people who teach and educate people, and the old people on the stage have seen this situation a lot.

When he just turned around, he had already written his name on the blackboard,

Guan Ping Dynasty.

Pushing down the thick reading glasses on the bridge of his nose, the old man said, "My name is on the blackboard, I have taken the graduating class for more than 30 years, and this year, you will be my last." ”

"Starting from next semester, I will be your math teacher and the leader of the third-year math group, and if you have any questions in the future, you can always come to the office and ask me."

When the old man faced his parents before, he had a smile on his face and looked very elegant and easy-going.

At this time, when it comes to teaching issues, he is meticulous and strict in the face of his students.

His teaching style seems to be a bit old-fashioned, and as he speaks, he picks up the chalk, turns around and writes a big question on the blackboard.

In the face of this kind of math teacher who "touches the ground" on the first day of school, the students of Puxi High School have shown excellent personal qualities.

Everyone did not complain at all, and they all buried their heads in "swish" and worked hard to answer.

Can be written and written,

Someone put down the pen.

Although in a school like Puxi High School, he basically completed all the high school courses in his sophomore year of high school, and the questions written by the old man definitely did not exceed the syllabus or anything.

But the thoughts of everyone on the stage seemed to have fallen into a dead end, and as they wrote, they lost their direction and could only look up at their peers with a blank face.

"What's this?"

"I haven't done it before."

"I don't think the final questions in the college entrance examination are so difficult, right?"

“......”

I have to say that after being a math teacher for so many years, the old man is simply a senior mobile question bank.

He used it as a question for the school-opening test.

A difficult problem, of course.

To be precise, it is a difficult problem specifically for top math students in the college entrance examination.

On the podium, the old man looked around the classroom, his gaze sweeping over the frowning and bewildered students!

In the last row, he stopped at the tall boy who was sitting idly idle, wearing a mask.

Soon, he looked away again.

When the parents in the back saw this scene, they hoped that their children would be able to answer, and at the same time they also whispered in the back.

Most of the parents of Puxi High School have no bad academic qualifications, and a few of them graduated from prestigious schools.

"Kid dad, do you know this question?"

"I'll see... It's a bit hard. ”

"kid, I just heard that you graduated from Shuangdan, this question..."

"Hey, after graduating for so many years, I returned all my math knowledge in high school to my teachers."

"Well... Coincidentally, so did I. ”

“......”

No way, high school math is actually difficult, and it is not at all understandable to ordinary people.

Those questions that you can't do in the college entrance examination will not be able to do it when you graduate from college.

......

Ahem——!

Suddenly, the old man on the stage coughed twice in a low voice.

He looked down at his watch, "Okay, it's almost time, everyone should have an idea, now I'll ask a few students to come up and answer." ”

"It doesn't matter if you don't get the final result, mathematics focuses on the cultivation of process and logical thinking, let me see your thinking."

As he spoke, the old man picked up the roll call book on the table.

In the roll call, after each student's name, he used a signature pen to write down the students' math scores in the final college entrance examination mock test of the last semester.

The top three students were all shouted.

It is worth mentioning that when the first two boys were called, and when the third called Xia Zilu, Li Xiufeng, who was sitting in the last row, took a look in surprise.

He could probably guess that the old teacher in front of him should be called according to the ranking, but he didn't ask much about Xia Zilu's grades, he only knew that it was okay.

However, girls are generally weak in science, but I didn't expect Xia Zilu to be okay in mathematics.

"Come on, Zilu."

When Xia Zilu got up slowly, Li Xiufeng whispered.

His voice was so small that only the people around him and in the aisle could hear it, but it still attracted everyone's side attention, after all, the boys in this kind of key high school are also more reserved.

Even if you really like a certain girl, this is a relatively low thing in their eyes.

Xia Zilu, who was shy by nature, didn't dare to look behind, and walked to the blackboard with a small step.

She didn't feel good in her heart to blame her cousin who took the time to help him hold a parent-teacher conference, so she had to complain that her mother Liu Jiahui was busy at the wrong time, and she couldn't come to the parent-teacher conference.

When Xia Zilu picked up the chalk, the boy with glasses and a gentle temperament next to him glanced at Xia Zilu, nodded at Xia Zilu and smiled slightly.

Xia Zilu knew him and knew that he was the science bully in the class, Chen Fan.

In the mock test last semester, Chen Fan ranked third in his grade in total and second in his grade with 146 points in mathematics, which was the object of Xia Zilu's envy. Rape Chinese

Jianghai High School has a full score of 150 in mathematics, and Xia Zilu can only get about 140 when she plays a long time, and usually 135 up and down.

Her total score is completely based on Chinese and English.

On the other side of Xia Zilu, who is also a science tyrant, Lu Yifa, ranked seventh in the last semester, but he is a little shorter, and his personality image is also a little rubbed.

When Xia Zilu came up, he didn't make eye contact with him, and Lu Yifa couldn't help blushing, and the chalk in his hand shook off a little dust.

Steady!

He said to himself, and then stared more seriously at the question on the blackboard.

Lu Yifa's grades are not as high as Chen Fan's, and his height is not as tall as Chen Fan's, but this time he already has an idea.

Today, we must make this question, so that the girl in my heart will take the initiative to cast her eyes.

Seven minutes later...

Lu Yifa fell into his own logical paradox, staring blankly at what he had written on most of the blackboard, and even encroached on a little of Xia Zilu's "turf" problem-solving process.

Where... Something seems to be wrong?

After struggling for a while, he turned his head a little stiffly, but his eyes lit up slightly.

Xia Zilu next to her, after writing a few steps, she couldn't write anymore, and she was looking down at the tips of her shoes over there at this moment.

Looking at the tall and handsome Chen Fan next to him, although his face was still calm, the slightly trembling chalk in his hand still exposed his heart.

Hehe... Load, you continue to load it for me!

Lu Yifa suddenly breathed a sigh of relief.

If this question comes up, and the two people next to him make it, but he doesn't do it alone, then Lu Yifa may be infinitely depressed this week.

But now, we're all the same!

Old man Luo's question should be done for those top Olympiad students, right?

Lu Yifa thought to himself in his heart.

"Alright, all three of you go down."

At this time, the old man on the podium spoke.

The three of them immediately put down the chalk with a sense of relief, turned around and bowed their heads and walked off the stage one by one.

Chen Fan is not a loser, he is the king.

When he got off the podium and passed by the girls' seats in the front row, he shook his head and said to himself, "It's a pity, give me two more minutes, and it should almost be solved." ”

Xia Zilu suddenly lowered her head when she heard this.

She was completely thoughtless.

really

Is this the world of top students?

The three of them returned to their seats, and the old man on the podium coughed dryly, just when everyone thought that they were going to comment on the next question.

The old man's gaze suddenly fell to the last row of the classroom.

There sat Li Xiufeng, who had nothing to do and didn't glance at the blackboard from beginning to end.

"That classmate, do you want to come up and try it?"

"Huh?"

"The most important thing to do math problems is to dare to take that step."

"Uh, me?"

"If you don't take that step, how do you know you can't?"

"Huh?"

“......”

At this time, several boys next to him also began to coax.

This kind of thing is always the best thing for students, regardless of whether they are in key high schools or ordinary high schools.

Li Xiufeng scratched his buttocks, feeling that today's parental meeting was a bit abstract.

I haven't heard of parents going up to do questions.

Could it be that this is Jianghai's upper-class high school?

It is difficult to be enthusiastic, and follow the customs of the locals, but Li Xiufeng couldn't help but sigh in his heart.

Back then, he was a student from a small county town in the mountains of Sichuan and Chongqing, why was he admitted to a key domestic university like Jianghai University when both English and Chinese were stretched.

Why?

It's a perfect score in math!

Li Xiufeng has always had a perfect score in mathematics since he was in elementary school.

In the year of the college entrance examination, he had a 150 in mathematics.

Not because he took the 150 exam, but because the full score of the exam paper was only 150.

Later, Li Xiufeng once sighed,

If the full score of mathematics is doubled to a 300 test paper, he may be able to get into Yanda and Mizuki...

......

At this moment, under the gaze of everyone in the classroom and the parents in the back row, Li Xiufeng, who was wearing a mask, walked to the blackboard like a duck on the shelf.

"Dust allergies?"

On the podium, the old man suddenly asked.

"Uh, no."

Li Xiufeng said subconsciously.

The next moment, he reacted and took off his mask with some amusement.

At this time, he was facing the blackboard, with his back to the people in the classroom, and in this atmosphere and environment, no one could recognize him so quickly.

Li Xiufeng took the chalk and looked at the title.

I have to say, math is too talented, it will be will.

No, the same question, slightly changed.

Then you still won't.

Li Xiufeng glanced at the question, and under the somewhat surprised gaze of everyone, he wrote in the middle of the blackboard in the empty space where Xia Zilu had just failed to solve the question.

Half a minute passed, and Li Xiufeng dropped the chalk.

On the blackboard, the detailed and clear steps to solve the problem point to the bottom step by step.

There were few scumbags present, after substituting Li Xiufeng's problem-solving ideas on the blackboard.

Everyone's faces quickly changed from shocked to abrupt, and finally showed their original expressions.

The parents in the back also whispered.

"Whose child is this?"

"It's pretty tall."

"You look handsome, too."

“......”

Xia Zilu opened her small mouth and looked at Li Xiufeng's back with a stunned expression.

It turns out that my cousin is not only painting, no, it is painting, but he also solves math problems so well?

Wait a minute!

Something seems to be wrong!

Isn't my cousin a pro?!!

Xia Zilu's eyes suddenly widened.

On the podium, the old man has been engaged in teaching for so many years, and he has obviously experienced strong winds and waves.

He knew that the real math demon was never a good student who followed the rules.

Li Xiufeng can answer this difficult question.

It can be said that it was not only beyond his expectations, but also it can be said that it is still in his expectations.

"Not bad."

The old man nodded quietly.

He didn't let Li Xiufeng go back to his seat, so he directly explained the problem to everyone according to Li Xiufeng's problem-solving ideas, and quickly picked up the blackboard and wiped an open space.

The next moment, the old man took out a book of exercises he had compiled from the black briefcase under the lectern.

Turned a few pages to this workbook, which is regarded as a "book from heaven" by ordinary students.

After he put it down, he turned around again and wrote the question on the blackboard, and the question type and question data all changed, only the question stem was a little similar.

This is going to be a question on the spot.

After writing, the old man handed the chalk to Li Xiufeng again.

"Try this question again."

Li Xiufeng, who was mistaken for a student, couldn't cry or laugh, thinking that he had become a little expert in doing questions.

However, for those who can do problems, doing this kind of thing is addictive, especially the moment when the problem is solved.

Four words, fluttering immortals.

Li Xiufeng took the chalk and glanced at the new question on the blackboard.

Under the podium, Chen Fan looked at this question and lowered his head and wanted to write some ideas on the straw paper, but soon found that he had written a line and a line, but he couldn't write a line.

Chen Fan in the second class of the third year is like this.

Not to mention the rest of the classroom, they all looked scratching their ears and cheeks at this time.

Lu Yifa's eyes were staring at Li Xiufeng's back on the podium.

He looked at the question a few times, and knew that he couldn't do it, and now the problem was the man...

Suddenly, the man moved.

It's still about half a minute.

The neat font of the board book, line after line, the dense and detailed problem-solving process is once again presented in front of everyone.

In the last step, Li Xiufeng wrote the answer.

On the seat, Lu Yifa's Adam's apple rolled and peeked at Chen Fan, who was pale, not far away.

Well, it's ok...

......

On the podium, the old man, who has always been strict with students and has a stingy smile, showed a slight smile on his face.

"Yes, what's the name?"

"Hmm, Li Xiufeng."

The old man flipped through the roster, as if he wanted to see Li Xiufeng's mock test scores in mathematics last semester.

After a moment, he looked up in some surprise.

"Huh? Not from our class? ”

Hearing this, everyone in the classroom was also shocked, they were all newly assigned this semester, and they were not very familiar with each other.

Li Xiufeng had a showdown, "Okay, actually, I'm not from this school." ”

"And which high school are you from?"

The old man was determined to find the root of the problem.

He knows the difficulty of his questions, and such good math seedlings are really rare.

"Jiang Da."

"Jiang Da... Jianghai University? The old man was stunned for a moment, but still asked, "How big?" ”

"Hmm... Freshman... On leave of absence. ”

After Li Xiufeng finished speaking, he added, "According to the time, it's almost a senior now." ”

"Take a leave of absence?" The old man was stunned.

At this time, Li Xiufeng also turned around.

Everyone under the podium looked at Li Xiufeng's back for a long time, and then looked at the side face for a while.

At this time, I finally saw his whole picture.

After a short silence,

The next second, someone suddenly shouted.

"! Isn't this Brother Feng? ”

"Brother Feng? KG's Brother Feng? ”

"That's him! You can't go wrong with being so handsome! ”

"Brother Feng, this is... Pros on campus? ”

“......”
