Open the brown paper bag, take out two hundred rolls from it, the contestants casually glanced, feel okay, after writing the name, number and region, the contestants entered the state of answering.

The first question is geometry, and there should be nothing wrong with it.

After all, it's worth points.

However...

When the contestants began to read carefully, they found that this question was not as simple as they imagined.

This...

Convex quadrilateral?

Since no graphics are given, this problem requires spatial imagination, which is slowly deduced by logical thinking, and then verified by mathematics... Although we all understand this principle, it is too difficult to do it.

If you simply find the angle, then you can use the formula for calculating the convex quadrilateral, but this problem does not give any numbers, just a few conditions...

This... Is this really a question for high school students?

Are you sure?

Most people don't skip this problem and start solving it.

But

In the process of derivation, all the contestants found a problem, they could not find any evidence about the derivation, that is to say, there is no evidence for the deduced things, and there are even errors in logic.

Oh, my God!

Which neuropathy is this?

What about the good questions?

Give it up...

Coming to the second question,

This group of people fell into confusion again, and they understood the topic, but after understanding it, they didn't have any ideas.

Skip!

Skip!

Skip!

Jump to the end, there is no jump...

At this point,

The contestants found out that this year's Zhejiang Provincial Olympiad Mathematics Competition is full of problems, and it is so difficult that it is not human, and even a score question is not given.

Who's out of this?

Is it human?

The expressions of all the contestants were a little depressed, and the atmosphere gradually became depressed, since this is the case, what else can be done?

Let's knock the first question first... It seems that this inscription is the least.

Everyone understands a truth that they can't solve themselves, and so do others.

The players in the field looked desperate, and the teachers outside the field looked confused.

“？？？”

“？？？”

“？？？”

This... What's going on?

I feel like the atmosphere of the game is a little wrong!

Why didn't anyone answer the question?

It seems to be all skipping the topic!

More than a dozen teachers who led the team are all veterans, and some have led the team more than once, but they have never encountered such a situation, and almost all of them are skipping questions.

How can it be?

These students are all math prodigies selected by municipal competitions, how can this happen? It's not just one or two students skipping questions, but a large number of students are constantly skipping questions.

This is not the norm of the past, unless the rules of the game are changed, or the difficulty increases.

Otherwise, it can't be like this.

"Teacher Wang?"

"It's... What's going on?" a teacher who led the team found a teacher from another municipal team and asked with a confused face: "I feel that something is wrong, the students shouldn't have this kind of expression, take a look... This is obviously an unsolvable problem. ”

"Who knows!"

"I'm also wondering... How is this possible?" the teacher frowned, as if pondering something, before he said, "I suspect... The questioner changed, replaced with one who likes to solve problems. ”

"That's what I thought, too. ”

Under the speculation of everyone, a conclusion was reached, that is, the difficulty of the question has been increased.

Superclass?

It shouldn't be possible... After all, it is a provincial mathematics Olympiad, and such a low-level mistake will not be made.

But who can explain this kind of thing clearly.

however

Among the teachers, Liang Fengliang, a teacher from the Ningshi team, seemed to think of a possibility.

The Xu Mang that appeared yesterday may not be an accidental event.

XU Mang,

Arena,

Puzzle...

All this is too coincidental, and there is only one possibility under such a coincidence, which is not a coincidence at all.

Don't...

Teacher Liang suddenly had a terrible idea, he thought that this time the problem was personally handled by Xu Mang, otherwise it would not be possible to have such a situation, you must know that this kind of thing, Xu Mang had done it, which directly led to the final mathematics results of the first middle school, and the whole army was wiped out.

I heard that the Chinese New Year... It's all miserable.

Two and a half hours passed in the game.

Very few people have completed the second question, and about seven people have completed the second question.

But

Soon, everyone found the loophole left by Xu Mang.

Questions 12 and 15 seem... There is a little hope!

Doing and doing,

The contestants found themselves deceived, and this question seemed to give a little hope, but in fact, behind the hope was all despair, because in the middle part, almost everyone was stuck there, and the idea of solving the problem was like a kite with a broken string.

“...”

“...”

“...”

Fuck off!

Who's up with the subject?

Long

Three and a half hours passed the game.

Half of the people completed two questions, a small part completed three questions, and the most awesome people completed three and a half questions.

The teachers outside the stadium were anxious in their eyes, and they found that their players were completely wrong, and they were full of autistic and desperate faces at a glance.

This...

It's over!

What about the rest of the game?

Facing the next challenges in this state of mind is definitely self-defeating... Thankfully, everyone is the same.

finally

The game is over.

The contestants don't know how they put the rolls in the brown paper bags, and they don't know how they get out of the field, in short, these players are just a shell without soul and thought.

"What's wrong?"

"Is the question difficult?" asked Liang Fengliang anxiously.

"Mr. Liang..."

"I..."

"I'm four hours... I only did one and a half questions!" A player from the Ningshi team, crying and sad, said angrily: "It's too difficult... It's so hard that I want to die, I feel like these topics are completely out of the program!"

What the?

Four... Done a question and a half in four hours?

Make no mistake, right?

Teacher Liang was a little incredulous when he heard this student's words, then looked at the other contestants and asked, "What about you?"

"I... I did two questions. ”

"I also have two questions. ”

"Two and a half questions. ”

"One question. ”

Hearing the replies of the other members, Mr. Liang also closed himself, this is no joke, right?

Two hours!

Not even half done?

Teacher Liang looked at the other teachers who led the team, and the result was also frightened.

"There's something wrong with this, the topic is definitely out of the outline!"

"Let's go, let's find the leader!"

"Yes!"

...

In the temporary office,

Xu Mang was lying on the chair, playing the game with a comfortable face, his King Glory technique has improved a lot recently, and he has changed this new number from stubborn bronze to order silver level, and his strength has been greatly improved.

Teammate A: wdnmd

Teammate B: wdnmd

Teammate C: wdnmd

With Xu Mang's efforts, the game ended in a fiasco.

"Cut!"

"Is there a way to choose a face with this kind of technique?" Xu Mang looked disdainful and silently started the next game.

pity

His account was sealed, this time for two weeks.

"it!"

"Actually report me?" Xu Mang was angry, unlike Yang Xiaoman, who had to win playing games, he had always taken a Buddhist attitude when playing games, which also led to the fact that he was going to die playing games.

Of course

can let the system cheat, but countless examples tell Xu Mang that playing games will be hammered by others.

"Hello?"

"What are you doing?" Xu Mang received a call from Yang Xiaoman and asked with a smile: "Oops... Stay up for a few more days, and I'll be back soon. ”

"I..."

"I miss you so much. Yang Xiaoman's weak voice came out of the phone, "I can't sleep every night... You know, I always feel like I'm missing something, and I'm not used to it. ”

“...”

"What is it?" asked Xu Mang.

"Nasty!"

"You... You're bullying me!" Yang Xiaoman's tone suddenly became shy, "Stinky rascal... You know how to bully me!"

Xu Mang: (°ー°〃)

Oh!

It turned out to be... Oops, this Nima...

"Ahem!"

"Xiao Man?" Xu Mang asked solemnly: "You are always not light or heavy, several times you almost ruined your happiness, if it weren't for my quick eyes... Do you still want children?"

“...”

"How can I have!" Yang Xiaoman said with a squeak.

Xu Mang was just about to speak, when the landline on the table rang.

"It's coming, I'll hang up first. ”

Words fall,

Xu Mang hung up the call and picked up the landline.

"Xu Mang!"

"Come to the game. ”

"Right now. ”

"Doot toot!"

Xu Mang looked confused, and it was Teacher Teng who called.

Is something wrong?

...

Xu Mang came to Mr. Teng's office, and when he pushed the door in, he saw Mr. Teng's face with black lines, as if he was autistic.

“...”

"Xu Mang!" Teacher Teng asked solemnly, "Is there any over-outline in this competition?"

"Huh?"

"No. Xu Mang said calmly: "How can I let the question exceed the outline, although it involves university content, but you can also see that I can use the knowledge structure of high school to solve the problem, there is no problem." ”

"This..."

Teacher Teng sighed and said helplessly: "Just now, the teachers of the various municipal representative teams came to me and said that the topics of this competition are out of line, because these players are all Tianhe elite talents selected from the municipal competition, and now they can't even do half of the questions correctly." ”

Xu Mang didn't feel anything about this, he had long known that there would be such an outcome, because these questions were all extended according to PUMaC, which was an international mathematics competition, and only five people from one country could participate.

Taking Yang Xiaoman, the champion of this international mathematics competition, as an example, listening to her own narration, she thought about the last question of the next day for half an hour, and wrote all the processes at the last moment when she was about to submit the paper.

One can imagine how flexible the topic is.

Of course

Xu Mang adjusted the question to the level of high school this time, and the difficulty was also reduced three times in a row.

Xu Mang sighed helplessly, and then said with a smile: "Teacher Teng, don't panic, this is just the beginning, withstand the pressure... After the competition, I solved the problem in front of everyone and used my high school knowledge!"
