There was not much to say about the opening ceremony the afternoon of the second day.

The leader's speech and the leader's representative speak.

Anyway, it's not Chinese, and it's also English.

There were simultaneous translation headphones on site, but few people brought them.

So that the Chinese team and the American team fought from time to time.

It's probably a few children who are more likely to show that trace of contempt with their eyes.

From this we can see that competition in the context of different civilizations is all-encompassing.

Even if you can use your eyes to express yourself, you should be proud.

It's just that the result of this competition is probably that both sides feel that they have won.

It has achieved the purpose of making the other party's heart empty just by looking at it.

Of course, the result will have to wait until the next day to go to the examination room to test.

......

At half past eight in the morning of the next day, the competition started on time.

Because the questions provided by the organizer are all in English, the interpreter who will follow the team in advance will translate the questions into the native languages of other countries.

Of course, if the candidate's English level is high enough, they can also read the original questions by themselves.

The team leaders of these countries have already explained to the candidates.

I'm afraid that the only thing that the team leader didn't explain was probably that before walking into the examination room, all the candidates saw fifteen curtain boards with white paper neatly placed at the entrance of the examination room.

"What is this for?"

Not to mention that the candidates have questions, even the team leaders of various countries feel inexplicable.

This is not the first time that most of the team leaders have led the team to participate in the International Mathematics Olympiad.

It's the first time I've seen so many screens placed in front of the prepared exam room.

Is there anything new to be played in this year's Mathematics Olympiad?

I stopped for a long time, but I didn't write a word on the white paper, which made people melancholy.

However, some people only feel agitated when they see this scene.

That's right, of course, they are the children of China.

Wang Yufei's plan was not hidden from them, but he didn't expect that these things were really prepared when he killed them.

So next, Wang Yufei really wants to solve a mathematical problem that plagues the world in addition to the Olympiad math exam?

Well, Wang Yufei has done everything he can do, and now what they have to do is probably not to hold their own people back.

Although they are all arrogant children, sometimes some people are not convinced.

......

The examination room was renovated from an empty auditorium.

So the curtain is actually placed behind all the candidates, that is, separated by a fence. You can see it when you look back.

But the candidates are professional after all.

It's just more than a dozen blank baffles, and naturally no one pays too much attention to it.

Everyone is here to compete for the rankings this time.

The time of the International Olympiad is even tighter, with four and a half hours to solve three questions, and each question leaves them only one and a half hours to think and solve the problems.

It sounds like a lot, but when you think about it, every Olympiad problem is the result of a bunch of mathematicians racking their brains.

The purpose is to comprehensively assess the ability of mathematical geniuses from all over the world, and the six questions cover all aspects of algebra, geometry, combinatorics, and number theory.

Each question is worth seven points, making a total of only forty-two points.

There are few points, so you must solve the problem very thoroughly to score, and if you accidentally miss a step in the test, you may be deducted points. Of course, you have to take it seriously.

In particular, each question is of different difficulty.

Generally speaking, the last question is the most difficult, and an hour and a half is not necessarily enough.

At this stage of the International Mathematics Olympiad, the test is no longer just calculation, but more mathematical imagination.

Then, shortly after most of the contestants had just finished solving the first question, someone stood up and submitted their answers.

That's right, not to go to the toilet, but to submit an answer sheet?

“？”

Many people recognized this figure.

Isn't this the one who wants to compete with the American team in terms of speed?

So this thing is serious?

He turned out to be serious?

Coming to the International Olympiad to compete in speed?

Many people subconsciously looked at the watch hanging on the large screen in front of them.

It's awesome!

Just one hour and twenty-five minutes later.

In other words, each of the three questions takes less than half an hour to solve.

The legendary fast gunner?

The children of the U.S. team were collectively stunned.

Can you really play like this?

Is this giving up a person's grades or trying to beat them in the total score?

Originally, everyone discussed and tried to finish it ten minutes in advance, so that six people could be one hour earlier.

But the other party alone was more than three hours ahead of schedule!

The Chinese are crazy!

This is the thought that pops into everyone's mind at this time.

However, the figure just silently walked out of the examination room, then stood in front of the neatly placed curtain board and stopped, then took out the pen in his hand and began to write on the cardboard.

The strange scene attracted the attention of many candidates, but at most, they looked back once or twice, and then forcibly focused their attention on the test questions in front of them.

Hemp eggs!

When others go crazy, they can't go crazy with them!

I've just finished solving this problem.

......

Of course, the candidates can't mess up, but after all, someone knows what Wang Yufei is doing.

Soon several mathematicians from all over the world gathered around.

Most of them are mathematics experts invited by the Organizing Committee of the International Mathematics Olympiad.

Even Phillips himself.

After all, agreeing to this unbelievable proposal is a source of curiosity.

He really wanted to see if there was really any member of the Huaxia team who could accomplish such a rebellious thing.

The test paper submitted by Wang Yufei has been taken to the members of the expert group for correction as soon as possible at his signal.

And now he and the other mathematicians want to see what problem the Chinese student is trying to solve.

......

Wang Yufei never cared about such a thing as someone onlooker.

He's there to hit opponents who deserve respect, and it's natural to get some attention in the process.

There is a truth that there must be gains and losses, and Wang Yufei still understands it.

And when you are really immersed in the idea of solving the problem, the brain can automatically block everything outside for a while, unless someone specifically talks to him, or there is danger coming.

But apparently no one would bother him at this time.

......

The twin prime conjecture is whether there are infinitely many primes that differ by 2.

I was interested in this because I studied how prime numbers can be used to structure data in algorithms.

In addition to this, there are the Mersenne primes and the Goldbach conjecture.

But for these two questions, Wang Yufei has not fully figured it out.

He just had a vague feeling that he could find the fifteenth Merson prime.

But he didn't want to make it public on the occasion. You can only use twin primes.

And number theory has always been the most talented test in the field of mathematics.

Soon, Wang Yufei wrote the first row of equations on the whiteboard.

S（α）=Σane（nα）；M，N∈ζ......

Then write faster and faster.

......

The answer was revealed, and he was going to prove the twin prime conjecture. ”

After Wang Yufei finished a piece of cardboard, a mathematician spoke.

"This kid ......"

"Chairman, the child's results are out......"

"Oh, wait, don't talk yet. The chairman, who was staring at the equation on the screen, said.
