My Identity As A Schoolmaster Has Been Exposed

Chapter 213

But this guy doesn’t ask himself, what he has to say, so he can play his game with peace of mind.

Xiaokang didn’t find himself lately. Xu Cong had a good time playing alone, winning streak in qualifying.

After saving enough money, Xu Cong went to buy new heroes and played with him. Xu Cong found that there was also a similar LOL Genting in the king, called the king simulation battle.

He came to be interested and tried a few of them.

“Similar to the Genting mode, but the same is very simple, just play around.”

Xu Cong had a little bit of understanding, and he also took a look on the Internet. He said that the magic seed is very talented and very popular.

The six heroes not only increase the attack speed collectively, but also have physical and spell blood sucking, as well as armor!

But the chance of this talent appearing is very low. If the talent doesn’t come out, it’s basically a waste, and it will be dubbed the devil’s eighth.

Eight people are playing chess on the board, and you are eighth if you have no talent.

Xu Cong smiled when he saw these guides, “This is challenging and worth playing.”

Lucky for the first game, the magic seed talent is here!

The spleen towards you!

No matter what the mage lineup or the assassin lineup, it is seconds!

Easy first!

In the second game, it was still the same.

The third game came again.

Xu Cong saw that victory was so easy. It was nothing like what was said in the post bar. He frowned and said, “This is so different from what was said on the Internet! I have been three times in a row. If you don’t play, you won’t play!”

How did he know that someone else begged his grandpa to tell his grandmother in order to play a game of Demon Seed’s talent, so he had to sacrifice himself for 30 years of being single!

After quitting the game, Xu Cong also began to feel bored, so he could only find something to do: “Find a few questions and brush them.”

Yang Kaixuan, with his ears pricked, stared at Xu Cong’s side, and Xu Cong was searching for questions on his mobile phone.

F*ck grin!

Suddenly, he stopped and stopped doing the question. Yang Kaixuan stretched his neck and looked over.

Problem: Let f be a mapping from the set {1, 2, n} to itself, define f(A)={b∉A, f(a)=b} for the non-empty subset A, if f(A )=A, then A is called a subset. Prove: There are exactly an odd number of fixed subsets?

Yang Kaixuan was confused after reading the questions, and Xue Laiyun, the math teacher who happened to be passing by, was also confused.

He and Yang Kaixuan glanced at each other, Yang Kaixuan’s eyes seemed to be asking: “Teacher, would you?”

Xue Laiyun quickly pretended not to see this question, and left them immediately.

If you don’t leave, is it possible to wait to be ashamed? Xue Laiyun fled in plain sight.

Yang Kaixuan was speechless, his gaze returned to Xu Cong, but Xu Cong didn’t plan to do this problem, he didn’t even get the pen!

But he read this question, and after a while, he brushed it away.

He is really writing questions!

Really swipe, the page on the phone is turned, this question is over!

Yang Kaixuan is puzzled, what operation, aren’t you doing the problem?

What’s the point of brushing it at a glance?

He didn’t expect that Xu Cong would pass it all at once!

If it were put on other people, Yang Kaixuan would definitely think he would not, but it was Xu Cong again, so he could not tolerate him not thinking in one direction.

The most credible thing is that Xu Cong saw that this question is too simple!

That’s right!

It’s too simple!

Yang Kaixuan asked tentatively: “Xu Cong, do you think this question is simple?”

Xu Cong looked over and said faintly: “It’s okay!

Yang Kaixuan curled his lips, just about to ask what to do, but he shut up, because it was too serious for him!

So he could only ask: “How did you find this question?”

Xu Cong told him truthfully: “I searched the Internet for the proof questions of the Mathematics Department of Tsinghua and Peking University, and there is it.”

“!!!”

Yang Kaixuan wanted to lick himself a big mouth, so why did he want to ask about it.

Xu Cong looked at Yang Kaixuan’s weird expression, and said to him: “Don’t think I know everything, so do I…”

Yang Kaixuan said excitedly, “Don’t you know this question?”

“No, no, I know this question, it’s that simple, who can’t… Uh… No, you will do it when you go to university.”

Yang Kaixuan’s face was black.

He doesn’t ask anymore!

Don’t watch Xu Cong anymore!

He was about to do his own test paper seriously, but he couldn’t help but glance at Xu Cong.

Xu Cong has been searching for topics on this side, but he didn’t write anything.

Several times when he took the pen, Yang Kaixuan got excited. Did he find the problem? But within a few seconds, Xu Cong shook his head and put the pen down again.

About ten minutes later, Xu Cong’s performance was still white.

“Could it be that there isn’t any question that can hardly hold this guy?”

Being puzzled, the get out of class bell rang.

Xu Cong put down his cell phone and said to Lin Mengjiao, “I put my cell phone here, you can watch it for me, and I will go to the toilet.”

Lin Mengjiao nodded very obediently: “Hmm!”

At this time, Yang Kaixuan stood up and looked at the question on Xu Cong’s screen.

Suppose the quadratic form f(x₁, x₂, x₃)=2(a₁x₂+a₂×2+a₃x3)²+(b₁×1+b₂x2+b₃x3)², mark

…

Yang Kaixuan took a look, and instantly got goose bumps and numb scalp. He looked at Lin Mengjiao and said to him, “Lin Mengjiao, can I see this question on Xu Cong’s phone? Just two seconds!”

After Lin Mengjiao glanced at him, she nodded.

This is far beyond Yang Kaixuan’s cognition. He wants to see how Xu Cong found such a topic!

What quadratic form?

What proof corresponds to the matrix? What unit vector? What standard form?

When he got the phone and tapped the screen, the search box above popped out.

above:

“Mathematics Department Postgraduate Examination Examination Questions” and at the end there is a “difficult” word!

Xu Cong is searching for real college entrance examination questions! And it’s a bit more difficult!

Yang Kaixuan put down the phone and took a deep breath. His eyes were blank and desperate.

Hemp egg!

What is the limit of this guy? Even the real exams for the postgraduate entrance examination can’t trouble him…

He has searched this from the university questions all the time. This is simple, and the other is simple, gradually increasing to the real questions for the postgraduate entrance examination.

What’s more terrible is that people don’t even look down on postgraduate entrance exams now! So what’s next?

Is it just a master’s and doctoral question?!

I rely on!!!

The key is that time does not allow him to find the subject of the postgraduate entrance examination. If it is allowed, not…

Hiss! I dare not think about it!

Yang Kaixuan has not dared to think about it!

When Xu Cong came back, looking at Yang Kaixuan’s eyes a little weird, he asked Lin Mengjiao suspiciously: “What’s the matter?”

Lin Mengjiao returned him: “He just looked at the topic on your phone.”

Xu Cong smiled and said to Yang Kaixuan: “Don’t look at them, these questions are not yours! They are mine.”

Yang Kaixuan was in the turbulent waves and asked tremblingly, “Xu Cong, where is your limit?”

Xu Cong did not answer!

It’s not that he didn’t tell, because he didn’t know, he was testing his limits just now.

Take a look, yes!

Look at two questions, it will!

Increase the difficulty, and the result will be!

No matter how difficult it is… then get out of class is over! He went to the toilet.
