"What?" When the words came out, all the students were stunned, and Xu Shiya also looked at Lin Fan in confusion, not knowing what the other party was doing.

"Lin Fan, hurry back to your seat and sit down for Lao Tzu, don't affect our study here!" Yang Dong, a member of the mathematics study committee, was angry and scolded Lin Fan.

"Hehe......"

Lin Fan smiled faintly, ignored him, straightened his waist, and walked towards the blackboard step by step with a calm and vigorous pace.

"Lin Fan, you are sick, get back for me!" Yang Dong felt that the majesty of his study committee had been challenged, and he was furious on the spot, and stretched out his hand to drag Lin Fan.

However, Lin Fan just waved his hand slightly, easily opened the other party, pushed the other party back to his seat heavily, and continued to walk towards the podium with steps.

"You ......"

Yang Dong was not convinced, glared angrily and wanted to go up again to stop him.

Lin Fan was not afraid, and a pair of eyes were also staring at him.

Seeing that a dispute was about to start, at this moment, Xu Shiya hurriedly stopped the two sides, looked at Yang Dong, and then at Lin Fan, and frowned slightly, "Can you do this question? You must know that this question is very difficult!"

Indeed, on the blackboard, this is a typical Huanggang problem, and very few high school students can make this problem.

Today, Xu Shiya specially took out this question to explain, just to prove her strength with these students.

But now, Lin Fan was a poor student who actually said that he could do it, which made Xu Shiya slightly surprised, and at the same time, looked at Lin Fan with a suspicious gaze.

"Teacher, he's disrupting classroom discipline! This question is so difficult, even I can't do it, he definitely can't answer it!" Yang Dong's eyes erupted with anger, glaring at Lin Fan viciously.

"What are you!" Lin Fan sneered, picked up the chalk and walked directly towards the blackboard.

"I'm nothing, I'm just a math study committee, I have the best math scores in the class, what about you? You're just a waste who doesn't even have academic performance, I'm not a thing, what are you?" Yang Dong trembled angrily.

"Hmph......" Hearing this, Lin Fan smiled faintly, he didn't bother to say anything more to him, for this kind of person, just slap his face directly, and he didn't even have to go through the procedure.

Walking to the blackboard with chalk, Lin Fan began to look at the question on the blackboard.

This is an equation problem, and one topic alone occupies as many as three lines, and it is also mixed with some knowledge related to pi, which is very complicated.

After reading this question again, Lin Fan picked up the pen and wrote it down.

"You...... Do you really want to do it?" Seeing that Lin Fan had already started writing, Xu Shiya was shocked, this is a Huanggang problem, many students with excellent results in the college entrance examination last year were stumped on this question, and now there are still very few people who can make this question.

Even many teachers didn't dare to explain this question to the students casually without absolute certainty, but now, how could she not be surprised that a poor student like Lin Fan was about to start doing it?

At the same time, many of the students below were also humming and laughing, they didn't believe that Lin Fan could answer it, in their opinion, Lin Fan was just pretending now.

"Hmph, can you make it, you can do it, I'll clean it for you for a month!" Yang Dong snorted and sneered, at this time, he is not in a hurry, when Lin Fan can't do it, he will be determined to be ugly, and when the time comes, he doesn't have to say anything himself, the spittle stars in the class can make Lin Fan unable to raise his head.

"Oh?" Hearing this, Lin Fan, who was writing the answer, smiled and turned his head to look at Yang Dong, "Are you sure?"

"Lao Tzu is sure!" Yang Dong glared angrily, the more he looked at Lin Fan, the more angry he became, he hated the other party's posture full of confidence.

He also couldn't understand where did a student with such poor grades get this kind of confidence?

"Then what if you can't do it?" Yang Dong looked directly at Lin Fan and asked with a sneer.

"If I can't do it......" Lin Fan suddenly paused in the middle of speaking, and a thought appeared in his mind.

Seeing that Lin Fan didn't speak, Yang Dong snorted and laughed, "What's the matter? If you do, get out of here, don't delay our class here!"

Hearing this, Lin Fan laughed, "Anyway, it's playing, do you dare to play bigger?"

"How do you want to play?" Yang Dong smiled, laughing extremely happily, anyway, Lin Fan couldn't do it, no matter how he played, he wouldn't suffer.

"Hmm...... So, if I make it, how about you clean the classroom for a month and run twenty laps around the playground, yelling at me as you run?"

When one sentence was spoken, some students laughed:

"Lin Fan, you're looking for death by yourself, you don't really think you can do it yourself, right?"

Yang Dong also smiled, "Then what if you can't do it?"

"Just like you, running twenty laps around the playground and yelling at me as I run!"

"No, you have to add, I'm Yang Dong's grandson!" Yang Dong had a slanted smile on the corner of his mouth.

"Okay!" Lin Fan didn't think about it, and happily agreed.

"You are looking for death by yourself, no wonder me!" Seeing Lin Fan agree, Yang Dong smiled, very proud, and only in this way could he dissolve the sullenness in his heart.

The two of them set the gamble so happily, for a while, all the students began to be excited, running ten laps around the playground, this is a big show, you know, the playground of Yunshan No. 1 Middle School can be a thousand meters, twenty meters down, that is twenty kilometers!

In an instant, many students began to get excited.

Looking at the scene in front of her, Xu Shiya frowned slightly, this kind of bet has already passed a little, she wants to stop all this, but she wants to see if Lin Fan can really answer, so she didn't make any moves.

After the bet was made, Lin Fan picked up the chalk and began to continue writing the answer.

For a while, the whole classroom was quiet, and all the students had smiles on their faces, as for whether Lin Fan's answer was correct, they didn't care, they only cared about when Lin Fan ran ten laps around the playground.

However, after only a moment, some students' smiles froze on their faces, because the solution process written by Lin Fan was exactly what Teacher Xu explained before.

At this moment, these solution processes appeared on the blackboard word for word, and some students were a little fierce, such a troublesome formula, can he write it after reading it once?

Xu Shiya was also stunned for a moment, she had written five or six lines in her previous answer process, and in just a while, Lin Fan had written them all down, which made her feel incredible.

However, Yang Dong was not in a hurry, there was still a smile on the corner of his mouth, this question had already been talked about by Mr. Xu just now, but it was not finished yet.

It is not unusual for Lin Fan to write down what Mr. Xu has said, the most important thing is the following steps, those steps are called difficult, even he doesn't have a clue, he doesn't believe that Lin Fan can write these steps.

However, as Lin Fan continued to write, soon, Yang Dong's smile froze on his face.

Because, the content behind this is something that Mr. Xu has not talked about at all, but ...... Lin Fan still made it, and according to the reasoning, the process he wrote was completely correct.

"This ......" Suddenly, Yang Dong was stupid, Xu Shiya was also stunned, and her eyes bloomed when she looked at Lin Fan.

"Impossible, how could he write the next steps?" Some of the students were shocked, and at this moment, they were all staring at Lin Fan, their faces full of incredulity.

"It's Teacher Xu, it must be Teacher Xu who is secretly directing!" Xue Meiqi whispered, and at the same time, a pair of beautiful eyes looked towards Xu Shiya.

In any case, she didn't believe that Lin Fan could solve this question.

Hearing this, Xu Shiya was furious and turned her head to look at Xue Meiqi, "Which eye of yours did I talk to him?"

"I ...... I ......" Xue Meiqi lowered her head and couldn't speak.

"Look...... He...... He really got the answer!" Suddenly, there was an exclamation, and in the blink of an eye, all the students' eyes were looking towards the blackboard.

On the blackboard, a complete solution appeared under the question, and some students who were better at learning immediately began to calculate to see if the answer was correct.

Soon, the results of the calculation came out, and both the process and the answer were completely correct.

In an instant, all the students were stupid, Tang Xiao's eyes shone brightly, and Xu Shiya couldn't say a word.

He ...... Didn't that mean that Yang Dong was going to run ten laps around the playground?" Suddenly, the fat tiger in the last row exclaimed.

He said a word, and for a while, Yang Dong's whole face was not good.

Jingle Bell ......

A pleasant bell rang for the end of class.

However, this pleasant bell for the end of class could not attract the attention of the students, and at this moment, their eyes were all focused on Yang Dong and Lin Fan.

In any case, they didn't expect that Lin Fan would really be able to do this question, let alone that Yang Dong would lose, at this moment, the eyes of all the students were full of shock.

"When a man speaks, he has to settle the matter, Yang Dong, let's run quickly! Don't forget to call you a fool!" The fat tiger in the back row laughed.

Although he often bullied Lin Fan, he hated Lin Dong, a member of the mathematics study committee, who relied on his good academic performance and gave him a bad face in the class, and finally had such an opportunity to retaliate at this moment, and laughed happily.

"Do you want to die?" Yang Dong was furious and glared fiercely at the fat tiger.

Fat Tiger sneered, he was not afraid of Yang Dong.

"Okay, let's get out of class!" Regarding this gamble, Xu Shiya didn't plan to take care of it, anyway, she was just running around the playground, and it wasn't too big.

On the contrary, Lin Fan's performance surprised her extremely much, and when she left the classroom door, she couldn't help but glance at Lin Fan twice.

Xu Shiya had just left here, and suddenly, several students in the class who had a good relationship with Yang Dong stood up from their seats and forced towards Lin Fan.
