"Classmate Li Wenqing, I'm sorry to delay you...... Can I ask you a question? ”

Xu Yun stopped at Li Wenqing's table, leaned over slightly and asked politely. On the other hand, Li Wenqing seemed to be frightened, and his body suddenly shook subconsciously, and Xu Yun's face was extremely embarrassed when he saw it.

I don't know, I thought he was deliberately playing a prank.

"Well, are you alright?"

"Ahh

"I'm fine."

"You're asking questions, right, asking." Li Wenqing came back to his senses and hurriedly pretended to be calm and generous.

Usually in school, others call her Wenqing or her full name, but she was suddenly shouted so politely by Xu Yun, and it was inevitable that she couldn't react for a while.

Although she was delayed, she didn't mind.

She didn't know much about Xu Yun, but she knew that the other party rarely talked to the female classmates in the class.

In addition, he was the last one to leave in the past few days, so it can be concluded that the other party is indeed just a simple problem.

So she was naturally willing to help.

"Thank you." Whispering thank you, Xu Yun moved the stool next to him and sat down in the aisle, handing over the test paper and scratch paper.

Li Wenqing did not twist, took the test paper, and carefully looked at the questions.

"Let me see."

"Let's find the trajectory of a charged particle in a composite field."

"It's actually not that difficult."

"The issues involved are mainly functions and geometry, and as long as the geometric trajectory is drawn, it will be easy to understand."

Facts have proved that Li Wenqing has no water in the first class, and he quickly determined the idea of solving the problem after just looking at the question, and explained in detail the calculation process in the draft book after speaking.

Physics and mathematics are not separated.

When Li Wenqing dissected its essence as functions and geometry, his thinking immediately became clear, and the whole person suddenly became clear.

"I see, it turns out that I have gone into a misunderstanding before."

pointed out his mistakes and did not forget to express his gratitude to Li Wenqing: "Thank you Li Wenqing. ”

"You're welcome."

Li Wenqing hurriedly waved his hand in response, and then handed back the test paper and draft book.

Although he was calm on the surface, he was a little surprised in his heart, but he didn't expect Xu Yun's comprehension ability to be quite strong.

After Xu Yun finished asking, he put the stool under his buttocks back and was about to turn around and leave, but his eyes inadvertently swept to the question that Li Wenqing was doing, and a strange look appeared on his face.

Coincidentally, Li Wenqing did exactly the math problem.

Or the conic curve he does best.

Originally, this was a very normal thing, but he found that Li Wenqing had miscalculated.

Thinking that people have just given themselves a topic, how can they watch the other party go further and further down the wrong path.

So he confirmed: "There seems to be something wrong with your calculation of this problem." ”

"Questions?"

When Li Wenqing saw this, he thought for a while that he was having auditory hallucinations.

Xiaoyuan's face was full of incredulity.

What's the situation?

She was actually questioned in what she is best at!

As the winner of the provincial prize in last year's mathematics competition, she admits that Xu Yun's understanding is very strong, but I am afraid that there is still some gap in guiding her.

However, Xu Yun didn't seem to notice Li Wenqing's expression, and still said to himself: "This problem uses the literal translation method to connect straight lines and curves, and it will be easier and more convenient to calculate through Vedder's theorem." There was a strong confidence in his tone, which made people embarrassed to doubt its authenticity.

It took dozens of points, and I almost fainted from hunger to understand the type of question I mastered in the overclocking state.

Xu Yun is certainly confident.

Li Wenqing listened to Xu Yun's method and knew that this was indeed the relevant solution of the conic curve, so he immediately put away his contempt and became serious.

Then he picked up a pen and made a quick calculation on the sketchbook next to him.

Not much.

The answer is on paper.

"It's really solved."

Carefully examining the entire problem-solving process, Li Wenqing was a little stunned, in addition to being secretly frightened, he was more embarrassed.

The dare lover did kindly point out his mistake.

In order to alleviate his embarrassment, he turned his head and said to Xu Yun in the next second: "I didn't expect you to have such a good grasp of the conic curve?" "Deliberately take the topic to a new place.

Hearing this, Xu Yun didn't think much about it, and said modestly: "Maybe I do more questions like this." ”

"I see."

Li Wenqing agreed on the surface, but in his heart he didn't know what to say.

When it comes to the number of questions to do, she said that she is the first in the class, and absolutely no one objects.

I think when she participated in the math competition last year, she was forced by Su Yushan not to know how many problems she had done, but in the face of this conic curve, she was stunned that she did it wrong, and the key was pointed out by others in person. But in order to maintain her usual quiet image, she had to resist the desire to complain until Xu Yun left.

After such an episode, she lost the desire to continue working on the questions, so she packed her things and went to the dormitory.

Xu Yun returned to his seat and noticed the back of Li Wenqing leaving, and he also planned to go back to the dormitory.

Originally, he still thought that he would leave early, and it was not appropriate for Li Wenqing to turn off the lights and lock the door at the end, after all, he had just given him a question.

And now I don't have that concern.

Two minutes later, Xu Yun walked alone on the campus road, thinking back to what he had done today.

blurted out: "Today is another fulfilling and harmonious day!" ”

……

……

High school normally has a four-week break, but there are no classes scheduled on Sunday afternoons.

You can go shopping outside the school or stay in the dormitory to do the laundry.

Of course, for senior high school students, self-study in the classroom is also a good choice.

The newly generated task requires asking 50 questions to classmates, and everyone is usually busy with their own affairs, and it is likely that asking questions to others will cause disgust. Therefore, Xu Yun decided to take advantage of Sunday afternoon to solve all the remaining forty-nine questions.

When I returned to the classroom after lunch, I could see about a dozen people working on the questions.

Among them are Li Wenqing and Liang Shuxing.

In addition to this, some people even brought meals to the class.

Learn as you eat.

Xu Yun walked silently to his seat, rummaging through and pulling out a few physics and chemistry biology test papers.

Then I thought about it and took another English one.

According to the requirements of the task, the problem asked by others must be something that he cannot do, so that the mathematics must be eliminated first.

You can only start with a subject that he is not currently good at.

"Each person asks seven or eight questions, and it should be about the same."

Raising his eyes to look at Li Wenqing, Liang Shuxing and several other top ten classmates in the class from behind, Xu Yun secretly calculated that he would complete this task today no matter what, and strive to draw random rewards again.

Thinking of this, Xu Yun quickly took a test paper, got up and walked towards Li Wenqing.

I had the experience of having a problem yesterday, and I helped the other party point out a mistake in the question, so it is naturally appropriate to ask her for advice now.
