"Zhou Qi, your score is okay. It's close to full marks. It's not like I didn't even finish the questions." In the high school substitute class on Monday morning, Qian Yudong looked at the two characters starting with the nine characters in the total score column on Zhou Qi's test paper.

Numbers, while expressing envy, I also didn’t forget to laugh at myself.

The test papers were sent out today, just as he expected, he failed to pass the high-level exam.

Although I haven't received my scores in numerical fractions and analytical geometry yet, it is estimated that there won't be much difference.

Originally, his mentality was quite good, and he thought that he would ask Xu Yun for more advice and review, so as to ensure that he would not fail the final exam.

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

It was as if he was the only green leaf in the dormitory, and the meaning of his existence was to set off the other three flowers.

"Maybe this is the fate of the deceased!"

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

"I don't know how many points Xu Yun got in the exam. It should be more or less than me." As he spoke, his eyes fell on Xu Yun next to him, and he didn't know what he was thinking in his heart.

After Tang Yanshan handed out the test paper to the classmates in the front row, Xu Yun's was not included.

It was obviously placed in a separate place.

Because of what happened in the examination room, as things unfolded on Sunday, many students in the mathematics department knew that a freshman had done the questions given by Tang Yanshan, which made them very curious about the final results.

Mainly, Tang Yanshan is very famous in the mathematics department, and many senior students have experienced the nightmare of being dominated.

But in recent years, the Department of Mathematics can count the number of people who actually asked Tang Yanshan to write the questions himself.

It’s impossible not to pay attention to it.

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 finished it in only half the time. This made them wonder whether the questions Tang Yanshan asked were as difficult as the rumors said.

So the final score becomes what everyone pays attention to.

"This guy Xu Yun is so perverted. He turned in the paper and left early just after half the time."

"There was a lot of hatred when he left."

Qian Yudong recalled what happened on Saturday and told Zhou Qi the scene with emotion.

Hearing this, Zhao Yuefeng, who was sitting in the front row, turned his head and continued: "My brother Yun's strength is something that no one else can envy."

Compared with the attention of others, Xu Yun's face looked very calm at the moment. He took Zhao Yuefeng's test paper and browsed it roughly.

I would like to know the difference between the monthly exam papers and the questions I did on my own.

Within two minutes, he understood why Tang Yanshan's question was called a nightmare by everyone.

Looking at it, you can clearly feel that the monthly exam questions are simple. The knowledge points tested are often relatively basic, and too many knowledge points are not included in one question. It is easy to understand and the calculation process does not have a lot of basis.

Question type.

If the monthly exam question requires students to saw down a tree, then Tang Yanshan's question requires the wood to be made into furniture.

The difference can be imagined.

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

"Xu Yun."

Tang Yanshan was still wearing a silver-grey half-sleeved shirt today, and his thick reading glasses could not hide the excitement in his eyes. There was always a double-layered glass filled with wolfberry beside the podium.

When Xu Yun's name was called out, a smile of joy could be seen on his face.

Under the gaze of classmates in the classroom, Xu Yun came to the podium and took the pieces of draft paper from Tang Yanshan's hand.

Tang Yanshan also announced the results.

"You really gave me a big surprise. You got full marks in both exams."

"Start next week and take professional courses with the sophomores."

When I said these words, my face was full of encouragement and joy. Being able to recruit such a good talent to the Department of Mathematics, maybe in a few years the status of the Department of Mathematics of Peking University will be even higher among domestic universities.

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

However, his smile was not because he got perfect marks in the exam, but because he was finally able to start studying the contents of his sophomore year.

For a person who is really well versed in mathematical knowledge, he can already determine the score when he completes the problem, so he is not surprised by the result of a perfect score.

But the others below were completely different. Almost as soon as Tang Yanshan said he had perfect scores, a commotion immediately broke out in the classroom.

First of all, Qian Yudong, Zhao Yuefeng and the others were happy for Xu Yun and couldn't help shouting twice.

"Brother Yun is too strong."

"Xu Shen."

However, their voices were soon drowned out by the comments from the surrounding classmates.

"I can get full marks on all the questions asked by Professor Tang, which is incredible."

"Is this the same freshman class as ours?"

"Isn't it said that the difficulty level of Professor Tang's questions is very high? Could it be that Professor Tang has let off steam this time?"

"I guess the questions this time will be similar to our test papers."

"You are still paying attention to the difficulty of the questions. Am I the only one who envies you for starting your sophomore year of study?"

…

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

"Wait a minute."

"Tell everyone the first question on my high-level examination paper."

"Lecture topic?" Xu Yun stopped and was a little surprised.

"You can speak if you are asked." Tang Yanshan stepped aside, picked up the cup and took a sip of tea.

Seeing this, Xu Yun had no choice but to pick up the chalk and face the blackboard. He copied down the problem first and then wrote down the process of solving the problem while explaining his own ideas for solving the problem.

The people who were still discussing in low voices below suddenly froze when they saw this scene.

After a while, I heard someone couldn't help shouting: "The question who just said it must be simple. You tell me this is called simple."

Yes.

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

The questions asked by Professor Tang are really as simple as the monthly exam, so why bother with that effort.

"This question looks complicated. It is both a matrix and a system of linear equations. The issues that need to be proved cover a wide range of topics."

"The first question is already this difficult. It feels almost like the final question in the monthly exam paper."

"To be able to get full marks on this kind of question is really worthy of me as a genius who wants to directly study the sophomore level courses."

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

As the students in the classroom sighed a few more times, it soon returned to the level where you could hear a needle drop.

Because everyone's attention was attracted by Xu Yun.

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

When this idea came to my mind, I was shocked.

"This is my entire 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 calculations."

After Xu Yun finished writing the last symbol, he said this in a deep voice to the classmates below, and then turned his attention to Tang Yanshan again.

"Xu Yun."

"You gave me another surprise today."

With a smile on his face, Tang Yanshan placed the glass next to the podium, freed his hands, clapped a few times, and then said with surprise on his face: "I didn't expect that in addition to your strong talent in mathematics, you also have a good way of giving lectures."

Your own way."

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

"Maybe it's because I gave more lectures in high school." Xu Yun answered with a shy smile.

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

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

"Brother Yun, you are so strong."

Zhao Yuefeng staggered his body to let Xu Yun in, without forgetting to praise him from the bottom of his heart.

As for Zhou Qi, who was sitting in the back row, he asked: "Can I see your test paper?"

"for you."

When Xu Yun heard this, without saying a word, he generously handed the pieces of draft paper to Zhou Qi.

Zhou Qi wanted to see what the questions asked by Professor Tang were like, but after reading all the big questions, he fell into deep thought.
