"Zhou Qi, your score is okay, it's close to a full score, unlike me who didn't even finish the question." In the substitute class of the eighth high school on Monday morning, Qian Yudong looked at the two digits at the beginning of the nine-character column of the total score on Zhou Qi's test paper, expressing envy and not forgetting to laugh at himself.

Today's test papers were sent out, as he expected, he failed the senior generation exam.

Although the scores and analytic geometry scores have not yet been obtained, it is estimated that there will not be much difference.

Originally, his mentality was okay, thinking that he would ask Xu Yun for more advice and review in the future, so as to ensure that he did not fail the final exam.

As a result, Zhao Yuefeng and Zhou Qi scored higher than the other, and Zhou Qi almost got a perfect score.

It seems that he is the green leaf in the dormitory, and the meaning of existence is to set off the other three flowers.

"Maybe this is the life of the chief!"

As soon as he sighed in his heart, Zhou Qi's voice suddenly came to his ears.

"I don't know how many points Xu Yun scored in the test, but it should only be more than mine." As he spoke, his eyes fell on Xu Yun next to him, and he didn't know what he was thinking.

After Tang Yanshan handed over the test paper to the students in the front row and sent it down, there was no Xu Yun in it.

Apparently put in one place separately.

Because of what happened in the exam room, as Sunday fermented, many students in the mathematics department knew that there were freshmen who did the questions Tang Yanshan, which made them curious about the final results.

The main Tang Yanshan is very famous in the Department of Mathematics, and many seniors have also experienced the nightmare of being dominated.

But what really made Tang Yanshan personally solve the problem, in recent years, the Department of Mathematics can't say that there is none, but he can count it with one hand.

You can't pay attention to it if you don't want to.

At this moment, some people in the classroom happened to be in the same examination room as Xu Yun the day before yesterday, and they all knew that Xu Yun had completed it in only half the time, which made them a little doubtful that Tang Yanshan's questions were as difficult as the rumors said.

So the final score has become a matter of concern for everyone.

"Xu Yun, this guy is too perverted, he was stunned and handed over the file in advance and left just after half the time."

"When he left, there was a big wave of hatred."

Qian Yudong recalled the situation on Saturday, and told Zhou Qi about the scene with emotion.

Hearing this, Zhao Yuefeng, who was sitting in the front row, turned his head and answered: "My Brother Yun's strength is not envied by others. ”

Compared with other people's attention, Xu Yun's face was very calm at the moment, and he took Zhao Yuefeng's test paper and browsed it roughly.

I want to know what is the difference between the monthly exam paper and the questions I did.

It didn't take him two minutes to understand why Tang Yanshan's question was called a nightmare by everyone.

Looking at it, you can clearly feel the simplicity of the question type of the monthly exam, the knowledge points tested are often relatively basic, and there is no too much knowledge content added to a question, which belongs to the basic question type that is easy to understand and does not have a lot of calculation process.

If the monthly exam question is for students to see down a tree, then Tang Yanshan's question needs to make furniture from wood.

The gap can be imagined.

Just when Xu Yun lost some interest in returning the test paper to Zhao Yuefeng, Tang Yanshan finally called his name on the podium.

"Xu Yun."

Tang Yanshan is still wearing a silver-gray half-sleeved shirt today, and the heavy reading glasses can't hide the excitement in his eyes, and there is always a double-layer glass soaked with wolfberries next to the podium.

When Xu Yun's name was called, a happy smile was visible to the naked eye.

Xu Yun came to the podium under the gaze of his classmates in the classroom, and took the few pieces of scratch paper from Tang Yanshan's hand.

In this regard, Tang Yanshan also announced the results.

"You really gave me a very big surprise, I got full marks on both exams."

"Let's take professional classes with my sophomore year from next week."

When he said these words, his face was full of encouragement and gratification, and if he could recruit such a good seedling for the Department of Mathematics, maybe it would not be a few years before the status of the Department of Mathematics of Beijing University in the domestic universities will rise.

After listening to these words, Xu Yun's expression finally changed a little, and a smile appeared on the corner of his mouth.

However, his smile was not because he got a perfect score, but because he was finally able to start studying the content of the sophomore year.

For a person who really understands mathematics, the score can already be determined by the time he finishes the problem, so he is not surprised by the perfect score.

But the others below were completely different, almost the moment Tang Yanshan said the full score, there was a commotion in the classroom immediately.

First of all, Qian Yudong and Zhao Yuefeng were so happy for Xu Yun that they couldn't help but put down and shouted twice.

"Brother Yun is too strong."

"Xu Shen."

It's just that soon their voices are drowned out by the comments of their classmates.

"Professor Tang's questions can get full marks, it's too against the sky."

"Is this the same freshman year as us?"

"Didn't you say that Professor Tang's questions are very difficult, but Professor Tang released the water this time."

"It is estimated that the questions this time are similar to our test papers."

"You are still concerned about the difficulty of the questions, only I envy that people are going to start studying the sophomore year."

……

On the podium, Tang Yanshan could naturally hear the voice below, and he didn't know what he thought, he suddenly stopped Xu Yun, who was about to go down.

"Wait."

"You tell me about the first question of my Gaodai test paper."

"Topic?" Xu Yun stopped, a little stunned.

"If you want to speak, you will speak." Tang Yanshan stepped aside, picked up the cup and took a sip of tea and said.

Seeing this, Xu Yun had no choice but to pick up the chalk and face the blackboard, first copy down the problem, and then write the solution process while talking about his own problem-solving ideas.

The people who were still discussing in a whisper at the bottom suddenly stiffened their faces when they saw this scene.

After a while, I heard someone shout: "Who said the question just now must be simple, you told me that this is called simple." ”

Yes.

After they saw the title written by Xu Yun on the blackboard, they realized how thoughtless what they just said.

Professor Tang's questions are really as simple as the monthly exam, so why bother with that effort.

"This problem list seems to be complex, it is a matrix and a system of linear equations, and the problems that need to be proved are quite wide."

"Is it already this kind of difficulty in the first question, it feels like it's almost the same as the finale of the monthly exam paper."

"To be able to get a full score in this kind of question, it is really worthy of a man of God who wants to directly study the sophomore course."

"When we meet in the future, we must call Xu Shen."

As the students in the classroom sighed a few more times, they soon regained the level of being audible when the needle dropped.

Because everyone's attention was attracted by Xu Yun.

They suddenly found that they had no idea how to solve the problem, but after listening to Xu Yun's explanation, they suddenly became enlightened.

When this thought came to mind, even I was shocked.

"This is my whole problem solving idea and calculation process, if you encounter similar problem types in the future, you can also try to use this method to solve the calculation."

After Xu Yun finished writing the last symbol, he whispered to the students below, and then turned his gaze to Tang Yanshan again.

"Xu Yun."

"You've surprised me today."

Tang Yanshan's face was full of smiles, and after putting the glass next to the podium, he first applauded a few times, and then said with surprise on his face: "I didn't expect that in addition to having a strong talent in mathematics, you also have your own way of lecturing. ”

"I believe that if you become a professor in the future, you will definitely be very liked by students."

"Maybe I talked a lot in high school." Xu Yun replied with a shy smile.

He really didn't expect Tang Yanshan to applaud himself in front of the students in the classroom, so that he didn't fully react.

Especially when he stepped off the stage and returned to his seat, he was greeted by many pairs of hot eyes.

"Brother Yun, you are so strong."

Zhao Yuefeng staggered his body to let Xu Yun in, and he didn't forget to praise him from the bottom of his heart.

As for Zhou Qi, who was sitting in the back row, he asked at this time, "Can you let me see your test papers?" ”

"Here you go."

Xu Yun didn't say a word when he heard this, and directly handed over the few pieces of scratch paper to Zhou Qi generously.

Zhou Qi wanted to see what Professor Tang's questions were, but after reading all the questions, he fell into deep contemplation.

"It turns out that the gap between me and Xu Yun is already so big!"

He has a clear understanding of Xu Yun's level, but that belongs to his subjective conscious judgment.

But after reading the questions that could be tested by Xu Yun with a full score, he realized that he still underestimated Xu Yun's strength.

At least if he is asked to do this test paper, not to mention getting more than 90 points like the monthly exam results, I am afraid it will be difficult to get half of it.

And after his emotions calmed down, he was faintly inspired by a fighting spirit in his heart.

It's like regaining the feeling of participating in the competition before.

In the following time, these scratch papers were circulated to each other in the hands of others, which made everyone admire Xu Yun more and more.

It seems that he has almost become a recognized god of learning for the freshmen of the Department of Mathematics.

Time passed quickly, and when the bell rang after class, Xu Yun did not go to the playground directly with Zhou Qi and Qian Yudong, but stopped Tang Yanshan in the corridor outside the classroom.

"What, you still have something?"

Tang Yanshan noticed that Xu Yun was coming over, and immediately paused and turned around to ask.

"There's something."

Xu Yun didn't mean to be tactful, and directly stated his purpose in the face of inquiry.

"I want to take a leave of absence from your class on Wednesday morning."

"Leave?" Tang Yanshan's face was a little suspicious, and he didn't know what Xu Yun was going to do after the holiday.

Hearing the doubts in Tang Yanshan's tone, Xu Yun hurriedly explained: "On Wednesday, the city will upgrade the city's surveillance image system, and our company is the party responsible for the project, so we may have to go over." ”

After this period of time, the company's personnel have basically completed the docking with the city monitoring system.

The city decided to officially conduct the test on Wednesday, and he, as an algorithm developer, will definitely be on site to deal with emergencies.

After listening to Xu Yun's answer, Tang Yanshan's eyes suddenly lit up, and he said with a smile on his face: "I heard that the city wanted to upgrade the monitoring system to create a safe and civilized city, but I didn't expect this project to fall on your company's head in the end." ”

"If it's approved for you, don't embarrass the Department of Mathematics of Beijing University."

"Don't worry, Professor Tang, I have confidence in my technology." Xu Yun assured categorically.
