Don't get me wrong, I really didn't mean to tease you

Chapter 18 Zhao Xueya's Frustration

There will be a grade-level unified examination on Friday, and the top [-] students in this examination can enter the top class.

In fact, Jia Yun doesn't care much about this so-called top class. It doesn't matter where he goes to study, but since he and his mother have already boasted about Haikou, the free Apple 4S is still worth fighting for.

In the past few days, the frequency of Jia Yun's visits to Zhao Xueya has obviously increased. Before he went to class 289, many people would yell and shout, but as the frequency increased, the people in the class would no longer be surprised.

Everyone has already acquiesced in the relationship between Jia Yun and Zhao Xueya.

Wen Guozhong, the head teacher of class 289, had a lot of opinions on this matter. He went to Lao Li more than once to protest, but Lao Li only said that Jia Yun went to Zhao Xueya for the purpose of studying, and that night, Wen Guozhong Also in the principal's office, he had seen the energy of the Jia family, so even though he was unwilling in every way, he could only hold back.

But to be honest, Jia Yun's improvement during this period is really fast. In the past, when Zhao Xueya gave him a lecture, he could only listen silently. Now, when encountering complicated questions, Jia Yun can already Discussed with Zhao Xueya.

Wednesday, sunny and cloudless.

In the afternoon after school, Jia Yun was still studying with Zhao Xueya.

When doing the five-year college entrance examination and three-year simulation in the morning, Jia Yun was stumped by a big math problem, and asked Zhao Xueya about it, but Zhao Xueya also took a long time to solve it.

“唔当a=8时，f(x)=1+√x/√1+x+1/3，求导可得.”

Zhao Xueya frowned slightly, holding a carbon pen in her white and slender right hand, quickly calculating on the draft book.

It's rare, after knowing Zhao Xueya for so long, this is the first time Jia Yun saw her stumped by a math problem.

"its not right"

After several times of derivation, Zhao Xueya's expression became a little anxious.

"This question is so difficult, I"

Zhao Xueya originally wanted to say that I wouldn't know either, but seeing the expectant expression on Jia Yun's face, she gritted her teeth and continued to bury her head in calculations.

The classroom was quiet, only the sound of the pen tip rubbing against the paper, accompanied by the breeze blowing in from the window, and the faint fragrance of Zhao Xueya's body.

After another twenty or ten minutes, Zhao Xueya finally came up with a result, but this seemingly complicated series of results are usually wrong.

As a top student, Zhao Xueya clearly knew it in her heart. She frowned when she saw the series of results she had deduced, and turned to ask Jia Yun:
"Is there no answer to this question behind May Three?"

"There is, but there is."

Jia Yun said:
"However, there is only one answer, the verification process is omitted, and the answer is that no matter a is any positive number, there is 1

Zhao Xueya sighed helplessly when she heard the words, and said:
"Oh, I may not be able to solve this problem."

"I'm sorry, Jia Yun, I really want to help you understand, but I..."

Seeing the guilty expression on Zhao Xueya's face, Jia Yun smiled and said:
"Oh, what's the point of apologizing? It's okay. I'll think about it myself."

Jia Yun moved the draft to his side, took a pen, and started the calculation again.

Zhao Xueya was a little surprised when she saw this.

"Have you got an idea?"

"Well, although the result of your derivation is wrong, there are a few key points in your derivation process that inspired me."

Jia Yun was writing hard on the draft paper, stopping to think from time to time, and crossing out and rewriting the wrong steps from time to time.

He was very devoted to this question, but he didn't realize that Zhao Xueya next to him was far more devoted than him, but Zhao Xueya's focus was not on the question, but on Jia Yun's profile.

The noon sun penetrated the window and sprinkled on Zhao Xueya's desk, shining on half of Jia Yun's cheek.

The golden sunlight fell on Jia Yun's hair, dyeing his clean and smooth black hair into a beautiful brown. His skin was fair and delicate, and there was not even a trace of blush on his delicate face. The lines are as sharp as a knife.

This was the first time Zhao Xueya observed a boy so closely and seriously.

"I figured it out! It can be solved in this way!"

Jia Yun suddenly had a flash of inspiration and shouted.

"Look, let's change our thinking and assume f(x)>1"

Jia Yun moved the draft towards Zhao Xueya, and began to explain his thoughts to Zhao Xueya.

But Zhao Xueya didn't listen to a word at all, she just stared at Jia Yun's side face in a daze.

"His eyelashes are so long."

"His eyes are so pretty"

"So, as long as you start from this direction, you will be able to prove it in the end. Er, classmate Zhao Xueya, are you listening?"

Jia Yun's cold voice pulled Zhao Xueya back from her fugue.

"Uh?"

Zhao Xueya's face turned red in an instant, and she hurriedly lowered her head, only to be surprised when she saw the derivation formula densely packed in the draft book.

"Wow! Did you deduce it?"

"Ah."

Jia Yun nodded.

"This question is really difficult to solve if you follow the conventional thinking, but as long as you change your perspective, first prove that 1/1+√x>1/√1+x, then it will be very simple."

Zhao Xueya stared blankly at the draft book, the shock in her heart was beyond words.

Wen Guozhong, the homeroom teacher, repeatedly warned her that Jia Yun was a poor student, and hoped that Zhao Xueya could stay away from Jia Yun.

And indeed, Jia Yun first came to her to ask questions that were not too difficult. At that time, she could tell that Jia Yun's foundation was very weak.

However, in just two weeks, he was able to solve such a complicated math problem by himself? !
This can't help but make Zhao Xueya suddenly have a very complicated mood.

On the one hand, she was happy from the bottom of her heart to see Jia Yun making such rapid progress with her help.

But on the other hand, this also made Zhao Xueya feel a sense of frustration.

Could it be that my three years of hard work can't compare to Jia Yun's sprint in the last three months?
Suddenly, Jia Yun's cell phone vibrated, and when he took it out, it was an unfamiliar number.

"Hello? Who is it?"

There was silence on the other end of the phone.

Jia Yun asked again, but the other party still didn't speak.

"baffling."

Just as Jia Yun was about to hang up the phone, the other person finally spoke.

"it's me."

Just two words, the voice is sweet, but the tone is very gloomy.

Of course Jia Yun will not forget this voice.

"season"

Seeing Zhao Xueya's curious eyes looking at him, Jia Yun hastily swallowed the word "Yao" back into his stomach.

Ji Yao would actually take the initiative to call herself? !

But Jia Yun remembered that he had saved Ji Yao's mobile phone number before, what happened to this strange number?

Oh, presumably Ji Yao has changed her mobile phone number, but she didn't know it.

　Uh, some math symbols turn into garbled characters when typed out, don’t take it seriously~
