In the monitoring, it can be clearly seen that Bi Qi, who was originally holding his chin and frowning, suddenly had a smile on his face, picked up a pen and began to calculate on the scratch paper.

He's ...... Got an idea!

Team leaders of various countries, you look at me, I look at you, big eyes and small eyes.

"It's fake!" one of the team leaders couldn't help but exclaim.

"Impossible, impossible. The other team leader also shook his head repeatedly, as if convincing himself, "How long has it been, less than ten minutes, has he?"

"Whether you believe it or not, I don't believe it anyway. ”

The third question is how perverted the level of difficulty, and the leaders of their group of national teams are all too clear.

Of the more than 600 people in the following venue, it would not be too surprising to say that someone had made this question completely.

After all, there are more than 600 people, and the appearance of two or three geniuses with a flash of inspiration is also expected by everyone.

But like Bi Qi, he only studied the third question for only ten minutes, and he had an idea to solve the problem, which is not realistic to think about it.

In the concept of team leaders in various countries, Bizzie did not find the right way to solve the problem, but was more likely to be trial and error.

Bi Qi had a full three hours to study the third problem, coupled with the strong strength he showed just now, many team leaders thought that Bi Qi could solve the third problem with a high probability.

But he didn't recognize that Bi Qi could find a way to solve the problem in just ten minutes.

After all, it's too psychedelic!

Unless......

Thinking like this, everyone looked at Gu Lu who was leaning back on the sofa again.

…………

"Hey, isn't this just a simple transformation application of Menelauss's theorem, and then solve the subgroups of all automorphic permutation groups in affine space?" Bi Qi patted his head and suddenly realized, "Such a simple question, why did I think about it for so long to figure it out, I'm so sorry for Mr. Gu!"

Menelauss's theorem, also known as Menelaus's theorem, was in the winter camp, and Bizzy remembered that Gu Lu had spent half a class talking about this theorem. The affine exchange group is one of the several concepts that Gu Lu has added to the national team in the past few days in London.

But what made Bi Qi feel a little remorseful was that it was obviously what Gu Lu had said, but he thought about it for a full ten minutes before he came up with the idea of using these two concepts to solve the third problem.

It's so undeserved!

Bi Qi knew that after the end of this IMO, Gu Lu's reproach would inevitably be avoided.

But at present, I still finish the question in front of me seriously.

…………

More than an hour later.

Bizzie put down his pen and rubbed his sore wrist.

"Doing the questions is also individual work!"

Bi Qi looked at the test paper filled with rows of formulas, and moved his somewhat stiff body with a wry smile.

After more than an hour of hard work, the third question, the most difficult question in the entire set of test papers, finally surrendered to his pen.

So far, Bizzy has completed the first day of the IMO, answering all three questions.

I looked at the time, and there was still an hour and forty minutes before the end of the exam.

"It's a little slower than I expected, but to be on the safe side, I'm going to check it again. In Bizzie's projection, he would only need two and a half hours to answer all three questions.

However, on the third question, I wasted more than ten minutes of time due to misunderstandings.

After looking around, the candidates who had not yet submitted their papers in advance appeared.

Bi Qi breathed a sigh of relief, then flipped the test paper to the first question, and hurried to start the first round of inspections.

Since there is a provision that allows early submission of papers, it is too much of a loss for Bi Qi to practice it untruthfully.

Moreover, submitting papers in advance is a tailor-made rule for some people.

For example, Mr. Gu.

Another example, yourself.

Ten minutes later, Bizzie finished checking it, and except for one or two minor details, Bizzie thought that his answer had been perfected and there was no need to continue the check.

Bi Qi is ready to hand in the papers and leave.

He looked left and right.

On the right, Ma Zhengxuan is tackling the third question, and his expression is unwavering.

For Ma Zhengxuan, Bi Qi is not worried at all. He didn't think that he could think of using Menelaus's theorem and affine exchange groups, and Ma Zhengxuan wouldn't have thought of it.

Judging from Ma Zhengxuan's character who has always sought stability, the speed is slower than himself, and it is no longer normal.

On the left, there is a member of the Korean team whose name Biqi does not know.

When Bi Qi was looking at Jin Antai, Jin Antai also seemed to notice it, and turned his head to meet Bi Qi's gaze.

The atmosphere was suddenly a little subtle.

Bi Qi smiled awkwardly but politely.

Kim An-tae's eyes revealed a look of doubt.

But then, that confusion turned into surprise.

In his sight, the Huaguo player sitting next to him stood up unhurriedly.

Bi Qi raised his hand and spoke to the invigilator who was patrolling,

"I want to turn in the papers!"

Voices spread throughout the venue.

Many candidates who were immersed in the questions raised their heads in surprise and looked at the first row, standing out from the crowd of Bi Qi.

Miscellaneous...... What the?!

Someone has already done it!

Many candidates glanced at the second question on their test papers, which proved that they were less than half of their progress, and looked confused.

Being watched by hundreds of people at the same time, Bi Qi didn't feel any discomfort.

On the contrary, there is a kind of summer from the scorching sun into the air-conditioned room, from head to toe comfort.

The comfort almost made Bi Qi moan.

Beside him, after Bi Qi said those words, Jin Antai's pupils shrank even more.

It was like a heavy hammer hitting Kim An-tae's chest, making it difficult for him to breathe for a while.

How could it be so bad!

Half an hour ago, Jin Antai had completed the answer to the second question, but from then to now, half an hour has passed, and Jin Antai still has no idea for the third question, and it can be said that he is completely in a predicament.

But on the other hand, the Huaguo player in front of him has completed the answers to all the questions.

An hour and a half apart, or even more......

This can already be described as bloody.

This gave Kim An-tae, who has a strong sense of self-esteem, a great blow.

It's not that Kim Antai hasn't lost, but it's the first time he's lost so completely.

Although this competition, from beginning to end, is completely wishful thinking on the part of Kim Antai.

Under the gaze of nearly half of the candidates in the audience, the invigilator came to Bi Qi.

After asking Bi Qi a few words, the invigilator put away Bi Qi's test paper and signed his name on a piece of paper.

"Can I go?" said Bizzie with a smile after all of this.

The invigilator nodded and made a gesture of invitation to Bi Qi, "Just leave at the door here." ”

Bi Qi nodded, and just wanted to leave, but it seemed that he suddenly thought of something, turned around, and looked at Jin Antai, who was in doubt.

"Come on!"

Bi Qi made a cheering gesture to Kim An-tae, and then drifted away.

Kim An-tae: "......"
