Chapter 127 What if the Enemy Has Gundam (13)

All the teachers and students in the Affiliated High School have no idea how terrifying Chen Xiaoxin is. They only know that Chen Xiaoxin scored 743 points in the city's joint entrance examination, and also got first place in this year's Shenhai Mathematical Competition. As for other things, such as what happened in Tianjiao Academy, the teachers and students in the Affiliated High School do not know.

But at this moment.
The teachers from the affiliated high school and Principal Zheng who were invigilating the exam looked at Chen Xiaoxin sitting there alone, frantically working on the test paper. His incredible speed made them drop their jaws. What was even more shocking was that he did not check his calculations on the scratch paper while solving the problems!

What's going on?
Such a complex question, such a tedious calculation process, he...he just started right away? Really no need for draft paper?

The teachers and the principal of the affiliated high school stared with eyes wide open in disbelief. They racked their brains but could not figure out the reason. They were originally wondering and puzzled why Chen Xiaoxin said the questions were too simple and there was no need for draft paper at all. However, now...the wonder and puzzlement were broken and replaced by shock, incomparable shock.

Humanoid supercomputer?

Does the brain have the same computing power as a supercomputer?

So is he still a human? This... This is definitely an alien!
The more you doubted Chen Xiaoxin at the beginning, the more embarrassed you feel now. It is hard to imagine how he did it. Anyway, Chen Xiaoxin, one of the twin stars of No. 2 Middle School, is finishing the test papers at a speed that is difficult for humans to understand.

At this speed
One hour? No, no, no. It doesn’t even take one hour. Maybe you can finish it in half an hour, and the whole exam lasts two hours.

"Are you just messing around or solving a serious problem?"

Li Qiulin, a special-grade teacher, was deeply shocked and murmured a little. He had met countless geniuses during his many years in the education industry, but he had never met someone like Chen Xiaoxin. He could no longer be described as a genius, but should be called a monster.

Those questions are very difficult and even beyond the syllabus. If you use high school knowledge to solve them, although you can do it, it will take a lot of time to write down the steps, and the calculation process is extremely complicated, especially the last three questions. They are definitely meant to torture students.

"Old Li?"

"Do you think Chen Xiaoxin is writing nonsense?"

A special teacher next to Li Qiulin secretly asked him, "He solved the problems too quickly. The questions were not easy at all, but he didn't even need a draft paper and started solving them directly. I was wondering if he did it by mental arithmetic? Can he figure it out?"

"do not know"

"But he was tapping the table with the tip of his pen, as if... he was making some kind of mark, some special mental arithmetic mark." Li Qiulin observed very carefully and deciphered some truth from Chen Xiaoxin's behavior. It was indeed a kind of mental arithmetic mark, but this kind of mark could only be used by him.

"hiss--"

"It's absolutely terrifying!"

The special teacher took a deep breath, looked at Chen Xiaoxin with a complicated expression, and murmured to himself: "Can our students keep up with his pace?"

Li Qiulin smiled bitterly and silently looked at the female devil Yan Xiaoxi in the corner. Although she was not as outrageous as Chen Xiaoxin, she was also very perverted and exaggerated. It was obviously a fair competition between the two schools, but it turned into a stage for the twin stars of No. 2 Middle School.

At this time,

Teacher Li thought of the words of the head of the Department of Mathematics at Fudan University.
——Be careful! Really be careful! The students of the Affiliated High School are indeed very good, but facing the twin stars of No. 2 High School, especially the student named Chen Xiaoxin, I can only say that the result will be embarrassing!

When I heard these words before, I felt that they were a bit exaggerated. Even if the twin stars of No. 2 Middle School were so powerful, the students of the Affiliated Middle School should not lose to an embarrassing degree. After all, these students were all geniuses who had been strictly screened and survived five rounds of elimination. Even if there was a gap, it should be very small.

结果
How terrible!
The students of the Affiliated High School all looked sad, but the twins of No. 2 High School looked like they were on vacation, with calm faces. In terms of expression management alone, they were so bad that they lost everything.

at the same time,

Principal Feng of No.2 Middle School was already pale with embarrassment, and wanted to find a hole to crawl into. Before coming, he repeatedly reminded him to be lenient! And before the exam, he advised him not to be too heavy-handed, and he agreed without hesitation.

did not expect.
I didn't expect this result. They beat me to death right away. Didn't we say that learning is not about fighting? Didn't we say that learning is about the ways of the world? Didn't we say that harmony is the most precious thing? Are emotions just a lie?

The head teacher, Tian Hui, also had a look of helplessness and bitterness on her face. She pursed her lips and said to the principal carefully, "Principal, I think it's better not to agree to requests like this in the future. Chen Xiaoxin is not careful when he hits people, and it's easy to hurt people by mistake."

"Um"

The principal nodded and whispered, "It seems that it is necessary to issue a statement. In the future, when something like this happens, our No. 2 Middle School promises not to send out the twins first."

It is true that these two people cannot be allowed to play. This is not a so-called competition at all. It is a one-sided massacre. Chen Xiaoxin and Yan Xiaoxi don't matter. They will just pat their butts and leave after the college entrance examination. What will happen to No. 2 Middle School in the future?
the other side,
Wu Tao from the Department of Physics at Fudan University looked at Chen Xiaoxin who was frantically working on the questions. He thought the questions were really easy and asked helplessly, "Are the questions from Lao Wang a little too easy?"

"Simple?"

"It's already difficult for high school students!" Director Wang was speechless at the moment, and said distressedly: "Although I thought it would be like this, I never expected it to be so outrageous. It's so embarrassing! Concentrate the best educational resources and select the 100 best students, and the result is..." Speaking of this,
Director Wang sighed and said helplessly: "The enemy has Gundam."

Wu Tao smiled bitterly and said meaningfully, "It seems that I need to temporarily change the questions in the physics class this afternoon. Although I feel a little sorry for the students of the attached high school, we can't compete anyway, so why not see how far we are from the Gemini overall."

shhhhh--

Chen Xiaoxin was working hard on the charming little monster with an extremely excited mood, peeling off the outer clothes on the little monster one by one, revealing their original appearance.

There are only three final questions left!

But to be honest, the questions this time were indeed interesting. The first seven questions took me a full 18 minutes, which would have been impossible in the past.

Chen Xiaoxin took a deep breath and quickly entered the state of reviewing the questions.
[Please prove that any line starting from one focus of an ellipse, after being reflected by the ellipse, must pass through its other focus]

Uh?
Starting to increase the intensity?
Even the derivatives are calculated?

The corners of Chen Xiaoxin's mouth couldn't help but curl up, his eyes revealing an indescribable desire to conquer. It was like going to a KTV to order girls, and after several rounds of "changing a batch", suddenly finding a lady he liked, he felt excited, happy, and delighted!
[Assume that the equation of the ellipse is x^2/a^2+y^2/, b^2=1, a>b>0, the focus coordinates are (±c, 0), c=√a^2-b^2, and (x0, y0) is an arbitrary point on the ellipse. When y0=0, the conclusion is obviously valid. Now assume that y0≠0, then the slope of the tangent through this point is tanθ=b^2·x0/a^2·y0]

There are only two places to calculate this problem. Substitute the tangent k of the angle between the connecting line and the tangent into the calculation using c^2=a^2-b^2 and x^2/a^2+y^2/, b^2=1 to get the value of k. Then find the slope of (x0, y0) and the other focus, and you can conclude that the tangents of the two angles are equal and the two angles are equal.

This is the end of the proof
Comfortable!

Sour and refreshing!

Chen Xiaoxin, the super boy who has never been satisfied, found unprecedented pleasure in these ten questions today. The feeling of happiness seemed to fill up his entire body and was about to overflow.

next question!
With the idea of ​​pressing on the victory's advantage, I didn't give myself a break and went straight to the next question.

OMG!

The difficulty has increased!
The joy is super doubled!
At this moment, Chen Xiaoxin's face was filled with an indescribable enjoyment. He couldn't help but turn his head and look at Director Wang of the Mathematics Department who was standing not far behind him. His eyes were full of gratitude. If it weren't for the large number of people, Chen Xiaoxin wanted to dedicate a song to Director Wang - Listen to me say thank you, because of you, the four seasons are warm
Stop it!

Do the questions!

Chen Xiaoxin buried his head in writing, pouring his youth and passion on the test paper.

at the same time,

Yan Xiaoxi also finished the first seven questions. She was working on the eighth question, and she was almost the same as the big devil. When the female devil saw this question, she was also full of joy and excitement. She didn't think much about it. She just picked up the pen and started working, working hard!
For a time,

There was a polarized situation at the scene. The students of the Affiliated Middle School were all gloomy-faced, crawling slowly in pain, while the twin stars of the No. 2 Middle School were like wild horses that had broken free from their reins, running freely on the vast grassland.

"headmaster."

"It looks like Chen Xiaoxin is almost done!"

Tian Hui peered at her student and saw that he was almost done. She quickly checked the time. Only twenty minutes had passed. She said cautiously, "It's only been twenty minutes since the beginning."

The principal of No. 2 Middle School was almost going crazy, especially when he thought about how he had promised Principal Zheng that he would show mercy.
Chen Xiaoxin.
Don’t hand in the paper after you finish writing it!
Even if I have to sit there and endure it, I have to endure until the bell rings!

Just as Principal Feng was praying in his heart, he saw Chen Xiaoxin slowly put down the pen in his hand and sit there quietly, seemingly trapped in some inexplicable emptiness.

Hold back!

You must hold it in!
Let’s give our sister school a little face!

Principal Feng had already held his breath, and his entire back was almost soaked with nervousness. But just when he was about to suffocate with fear, he saw Chen Xiaoxin suddenly raise his hand.
"carry out an assignment!"

A loud voice broke the silent air.
