Reborn Xueba, you don't really think that studying is difficult, do you?

Heaven and earth conscience.

Ge Tianxing really wants to drive people away.

Originally, he came here with high ambitions. He thought that after retirement, he could train two top-level Mathematical Olympiad geniuses for the country, and then go abroad to win glory.

But in the end, these are two top... No, it is true that they are arcane geniuses at the super monstrous level, but they don't need his training at all, because the other party has reached the full level directly.

This feeling is like a strongest king running to Xinshou Village to pretend to be a force, but in the end he directly meets two hundred-star kings, really don't feel too sour!

only……

As a king, Ge Tianxing also has his own dignity and arrogance, and he will definitely not really chase people away.

at the same time.

Regardless of whether it was Zhao Qinghan or Lin Bei, they would not let Ge Tianxing go so easily.

After all, Ge Tianxing had already produced three papers. Although Zhao Qinghan and Lin Bei quickly produced them, it did not mean that these three papers were worthless.

On the contrary, its value is still very high.

Of course, except for the first entry-level paper, the difficulty is too low, so there is no need to do it.

But the difficulty of the second and third parts is still barely noticeable, especially the third part, which is quite interesting.

Take the example of eating.

The first paper is comparable to bran swallowing vegetables. It’s okay to fill your stomach when you’re hungry, but you don’t want to eat it now.

The second paper is barely a side dish of porridge, which can nourish the spleen and stomach and store a little energy.

The third roll is comparable to a minced meat dish. Eating it can strengthen the muscles and bones, and increase the strength of the meat.

and so……

Lin Bei and Zhao Qinghan would not give up until they had wiped out the second and third dishes in Ge Tianxing's collection.

Besides, they are even more looking forward to the future, will there be bigger and richer delicacies?
Such as braised pork belly, sea cucumber with green onions and so on.

After all, Ge Tianxing has been famous for decades, and everyone calls him the Emperor of Exams, and he has the title of professor. He should have a lot of goods in his stomach, and he shouldn't be too barren!
Not to mention sea cucumbers with green onions, if you don’t even have braised pork belly, steamed herring and other dishes.

That Ge Tianxing is really going to be looked down upon by them.

Ge Tianxing: "%￥#@#￥%..."

At this moment, he really wanted to say mmp without any scruples. Lin Bei and Zhao Qinghan were really deceiving people too much.

Even though the two of them didn't say a word, they both looked at him with a pair of big eyes, and the suspicion in their eyes was self-evident. If he couldn't come up with a better question, his reputation would be completely ruined. , but also be underestimated.

Nima, being looked down upon by two little dolls who are not much older than his grandson, how can he bear it?
"This, but you forced me."

"It's you who insist on forcing me to make a super big move, so today I will show you my true strength."

"I think back then, I was the existence that terrified countless students. Who didn't scold me in their hearts for not being able to die?"

"I think back then, I served as the coach of the National Mathematical Olympiad Training Team many times. Among them, in the 90s, I led students to crush countless foreign talents and won the first gold medal."

"It's just that in the past ten years since I retired, the old man has paid attention to self-cultivation and self-cultivation, and his murderous aura has gradually disappeared."

"I no longer pursue extreme difficulty in setting questions, but start to consider the strength of more people and take care of ordinary people as much as possible, so the questions I ask are more popular."

"But it's a pity that I originally set my heart on the bright moon, but the bright moon shines on the ditch. I think about the public, but you two little dolls dare to despise and underestimate the old man."

"Then I won't hide my clumsiness anymore."

"Today, I have to let you know the real reason why I used to march out in the sky, no grass can grow and Ge Bushi can't be killed. If you don't overthrow you, I will write my name upside down."

At this moment, Ge Tianxing seemed to have broken some kind of seal on himself, and suddenly became murderous and hostile.

Although it doesn't look ferocious, but it is enough to make people daunting. When the child saw it, he stopped crying instantly.

Then he stopped taking general papers from his bag, and went directly to the blackboard to touch a piece of chalk, and began to write quickly on the blackboard.

After 1 minute, a question was freshly released.

only see...

[Assume that D is an acute triangle ABC (AB>AC), with a point inside, so that ∠DAB=∠CAD. 】

[The point E on the line segment AC satisfies ∠ADE=∠BCD, the point F on the line segment AB satisfies ∠FDA=DBC, and the point X on the straight line AC satisfies CX=BX. 】

[Assume that O1 and O2 are the circumcenters of triangle ADC and triangle EXD respectively, and prove that straight lines BC, EF and O1O2 are at the same point. 】

Looking at this topic, you can instantly get goosebumps?

If not, there are only two reasons.

First, the strength has reached a certain limit, which is comparable to unimaginable, and it is rare to have an opponent in solving problems in the world.

The second is that he is a scumbag, a piece of vegetables, who can't understand the difficulty of this question at all, so he doesn't feel it.

You must know that although this is a geometry problem, it is not as difficult as a function problem at first glance, but it is actually a very complicated geometry problem. It is rare for one in a million students to prove it. After all, this is 2021. It is one of the real questions for the first round of the 62nd International IMO Competition.

Although it is the first round of optional big-axis real questions, the difficulty is the same as the first round of IMO big-axis real questions.

It's just that in the case of no problems in the first round, this alternative real question has not come out.

Outside, few people know.

But a big guy like Ge Tianxing naturally knows it.

Then he wrote it eloquently, and he couldn't believe that Zhao Qinghan and Lin Bei couldn't be bothered.

"Hehehe!"

"Two young puppies, dare to underestimate this old man. Are you too careless, or is this old man unable to hold a knife? What a joke. If I don't put you down today, people will really think that I am not dead. Got three eyes."

While secretly complacent, Ge Tianxing folded the chalk in his hand into two pieces and handed them to Lin Bei and Zhao Qinghan respectively, "Come on, come on, give you the chalk, come up and explain it."

"Now at 8:35, as long as you can solve the problem at 9:20, a total of 45 minutes, that is, before the end of the next exam, you are really good."

Ah!
There is still plenty of time.

A full 45 minutes.

But Ge Tianxing is confident, let alone 45 minutes, even if it is doubled, Lin Bei and Zhao Qinghan may not be able to solve it.

Even though the two have strong basic strengths, they have not been exposed to orthodox Mathematical Olympiad training after all, and they don't know much about this IMO axis question, so it must be a certain degree of unfamiliarity.

But in the next second, it was still a classic face slap.

I saw Lin Bei and Zhao Qinghan looking at each other, and they could see a strong fighting spirit in each other's eyes.

Then Lin Bei spoke first, "Student Zhao Qinghan, do you dare to tell the truth, how long will it take you to do this question?"

"Less than 5 minutes."

Zhao Qinghan rolled her hair, and her pretty face was full of confidence.

Hearing this, Lin Bei's pupils shrank sharply, as if feeling great pressure, but the corners of his mouth curled up slightly, "Hehe, coincidence, I only need 4 minutes."

Zhao Qinghan: "..."

Good guy, are you playing chicken stealing?
"Isn't it just 4 minutes?"

Zhao Qinghan gritted her teeth tightly, flashes of lightning flashed in her eyes, and said indignantly: "Maybe I didn't make it clear just now. What I said was less than 5 minutes, but in fact, 3 minutes is almost the same."

"After all, Hua Xiong is mere, why bother to borrow wine, as long as he has a knife in his hand, he can be chopped off with just one swing."

Lin Bei: "%￥#@#￥%..."

No longer talking, Lin Bei and Zhao Qinghan refused to accept anyone at the moment, and directly took the chalk from Ge Tianxing's hand and walked to the left and right of the blackboard, each taking half and answering quickly.

"Da da da……"

"Da da da da da..."
