And it was when Ye Feng was still sleeping.

The class bell rings, and a teacher walks into the classroom!

Her name is Teacher Liu, and she is the math teacher in Ye Feng's class, and she has always been very strict.

"Students, in order to prepare for the joint entrance examination of the ten schools, I decided to change this self-study class to mathematics and take out your test papers. ”

The students hurriedly took out the math test papers and looked at the blackboard intently.

Joke, this is Mr. Liu's class! Who dares not to listen carefully?

"Hey, wake up, this is Teacher Liu's class, you don't want to live anymore!"

Ye Feng's tablemate kept poking Ye Feng's shoulder with his hand, trying to wake Ye Feng up.

Of course, no one cares about sleeping in self-study class, but this is Mr. Liu's class!

This Teacher Liu, because she is a female teacher, likes to rectify some students who disrespect her.

There was once a person who slept in Teacher Liu's class, and was directly kicked out of the class by Teacher Liu, and later alarmed the principal, so that the classmate was barely expelled.

"Hmm. What he didn't expect was that his tablemate, after answering the call, stopped caring and continued to sleep.

"Hey!" sighed silently.

He wanted to take care of it again, but Ye Feng responded by continuing to sleep.

In the end, he had no choice but to listen carefully.

"Students, today we are going to talk about functions, this is a major test point of the college entrance examination, this question is the college entrance examination question in southern Jiangsu Province last year, but it is very difficult, take good notes. ”

Teacher Liu was wearing a purple dress and glasses, full of intellectual temperament and a dignified tone.

Now in their third year of high school, students are about to face a turning point in their lives!

Thousands of troops have crossed the single-plank bridge, but they can't relax at this juncture!

"Zhou Wei, you are the representative of our class in math, you can give it a try!"

She quickly smiled and said to Zhou Wei in the seat, Zhou Wei's grades have been very stable, and he is even better at mathematics, and he is the top student in the class.

Zhou Wei stood up.

But he looked carefully at the title on the blackboard, and his brows furrowed deeply!

After a long time, Zhou Weicai said squirmingly: "Teacher, I didn't understand this question. ”

When he said this, Zhou Wei's face was already red to the base of his neck.

As a squad leader, I can't even do the first question, and this shame is also thrown home.

"Well, the teacher said that he understood, after all, this question is already difficult in college, and not many people did it in the college entrance examination last year. ”

"In that case, Su Xiaoting, you can try it!"

Teacher Liu immediately looked at Su Xiaoting.

Full of anticipation.

Su Xiaoting is the best student in the class in mathematics! And she is also the first in the class, if even she can't do it, then no one in the class can do it.

"Okay, teacher, I'm willing to try. ”

Su Xiaoting's crisp and pleasant voice sounded, stood up, and walked towards the blackboard.

"Wow, she's going to do it, she's going to do it, right?"

"Hey, after all, there are top ten in the grade!"

Many people looked at Su Xiaoting with longing in their eyes!

This is the goddess of the class, and many students adore her, even the girls admire her immensely.

"It's worthy of Su Xiaoting, such a difficult topic, but the pen is flying!"

Some students whispered.

At this time, Su Xiaoting had already written the process of solving the problem on the blackboard, which was extremely fast, and she knew that she was extremely thoughtful at a glance.

But her speed gradually slowed down.

Halfway through it, I couldn't write anymore.

"Teacher, I can only solve half of it, and the remaining two questions don't have any ideas. ”

Su Xiaoting's forehead was also covered with sweat, and she was a little powerless.

It's so difficult!

Even if it was her, she could only solve the first two questions at most, and as for the last two questions, she couldn't even read them!

"Hey. Teacher Liu sighed, but also expressed understanding, and then said: "This is also normal, after all, it is the finale of the college entrance examination, and Su Xiaoting can make two questions, which is already very good." ”

"Next, I'm going to tell you about the pitfalls in this question. ”

Teacher Liu glanced at all the students in the class, looked attentive, and said slowly.

But it's just now.

She saw the disharmony in the class.

A classmate, sleeping!

And that person is the one who has always been at the bottom of the class - Ye Feng!

"Okay, very good, it's all at this critical juncture, and there are still classmates who don't know whether they are alive or dead, and openly sleep in class?"

Teacher Liu's tone was very angry, sleeping in her class, not only challenging her authority, but also doubting her teaching standards.

This naturally made her very angry!

"Ye Feng! It's you, and you dare to sleep, are you a pig?"

Teacher Liu pointed at Ye Fengdao angrily and gritted his teeth.

"Hello Mr. Liu. ”

Finally feeling that something was wrong with the atmosphere of the classroom, Ye Feng slowly opened his eyes and sat up.

As soon as I opened my eyes, I saw an angry Mr. Liu.

Ye Feng didn't know what was going on at all, and he was even more confused when he stood in his seat at this time.

"Ye Feng, are you a pig?" asked Teacher Liu with a glare.

Some were said to be lazy by the teacher, and some were said to be slippery by the teacher, but they were said to be pigs by the teacher, and Ye Feng was still the first.

The classroom burst into laughter, and some even burst into tears.

"Can you solve this problem? and dare to sleep?"

"If you can't solve it, go and run ten laps along the playground for me honestly!"

It seems that he still can't understand his hatred after scolding Ye Feng as a pig, and at this time, Teacher Liu's teeth are trembling.

She had never seen a student wake up from class and sleep with a look on his face as if he was nothing.

The more Ye Feng seemed to be unfazed, the more angry the anger in Mr. Liu's stomach burned.

It's just that before Teacher Liu finished criticizing, Ye Feng had already left his seat.

Many classmates thought that he was running directly to the playground, but they didn't expect Ye Feng to walk directly towards the blackboard!

"The bottom student dares to solve the last big question, it's really beyond my strength!"

"That's right, even Su Xiaoting can't solve this problem!"

Seeing that Ye Feng really came over, Teacher Liu's face also showed a little surprise.

It is generally the same as Su Xiaoting's answer, but the idea is more concise.

"It turned out to be a copy of Su Xiaoting's answer, who wouldn't know this, I can do it too!" Zhou Wei looked at the answer written on Ye Feng's blackboard, and was the first to coax.

Teacher Liu was still frowning.

Streamlining the answer looks simple!

But if you really want to do it well, it's definitely a hard thing to do.

Removing redundant parts of the answers without losing points on the question requires a high level of proficiency in such questions.

After the first two questions came up with the same answer as Su Xiaoting, Ye Feng stopped.

This can't help but make people suspect that Ye Feng just happened to miss some unimportant parts when he was copying the answers.

Teacher Liu sneered.

I overestimated a bottom student just now, it's really stupid!

It was also getting more and more lively under the podium.

"I won't write the answer after copying it, Ye Feng, you better come down!"

But Ye Feng didn't pay attention to it at all, he just turned his head to look at Teacher Liu.

"Teacher, can I use the optimal solution?"

As soon as these words came out, Mr. Liu was also stunned for a moment.

At this time, there is no one in the class who is not confused.

What does optimal solution mean?

Could it be that Ye Feng can still have multiple solutions?

Zhou Wei sneered below, I can't solve this problem, what kind of awesome are you bragging about at the bottom!

Even Su Xiaoting frowned, she knew very well how difficult this question was.

Superfluous solutions simply don't exist!

As we all know, the more complex the problem, the more singular the solution is!

There is only one set of standard solutions to this problem.

But Teacher Liu still nodded, at this time, in her eyes, Ye Feng was a clown on the stage.

She just wanted to see what other tricks Ye Feng could play!

Ye Feng no longer pauses!

The chalk in his hand flew like a fly, leaving line after line of answers on the blackboard.

After Su Xiaoting below saw Ye Feng's answer, her face was full of doubts that she couldn't understand, and the other students couldn't understand it.

"You wrote all the formulas wrong, and those symbols, did you create them yourself?"

Zhou Wei was the first to hold back, and immediately laughed.

In Ye Feng's answer, there are many things that the students in the audience can't understand.

For a while, there were more and more people who laughed at Ye Feng!

Su Xiaoting looked at Ye Feng's formula and didn't look like it was scribbled, she hurriedly opened the textbook.

After searching around, Su Xiaoting did not find similar formulas and symbols.

She had to shake her head helplessly, it seemed that Ye Feng had misremembered the formulas and mathematical symbols.

Just when the class was getting more and more lively, Teacher Liu's expression became more and more solemn.

She really wanted to say that Ye Feng's answer was wrong!

But as a teacher, she had to tell the truth.

"Ye Feng's answer is right!"

"He didn't use high school content to solve this question, but calculus!"

Hear the words.

In an instant, the audience was shocked!

Silence, death-like silence.

The whole class went up and down, and for a while, there was silence, and the needle drop could be heard.
