Fernando's pupils shrank. He has experienced dozens of mathematics competitions, so he naturally knows the importance of the word "guidance". Even if he has a perfect score for the gold medal in the Mathematical Olympiad, he is not qualified to "coach" the silver medalist Eba.

"Eba's has only top math coaches.

Could it be said that this "QIN KE" is much more powerful than the beautiful "NING" in front of us?

Although Fernando is arrogant, who can win the IMO gold medal with full marks? Who is not a calm and thoughtful person? He quickly regained his composure and turned his attention to Qin Ke again: "Are you sure it's just the two of you?

Come and challenge the five of us?”

Qin Ke smiled easily: "Actually, one is enough for me. I mainly want her to increase her confidence and gain experience in solving questions under huge pressure. This will be very beneficial for her to participate in IMO in the future."

Fernando looked at Qin Ke for a while, and then a serious smile appeared on his lips again: "Very good, your arrogance successfully aroused my fighting spirit. To be honest, even if it is faced with the challenges of your three Mathematical Olympiad training teams,

, I never took it seriously, but at this time, I decided to go all out."

He looked at Ning Qingyun again, his eyes full of teasing: "I believe that you two should be the high school students with the highest level of mathematics in Xia State. If we defeat you, we will be equivalent to defeating a country. It is indeed interesting."

For Fernando, he once stood at the top of the World Mathematical Olympiad through the IMO gold medal, but he actually defeated only national Mathematical Olympiad teams from all over the world, which added up to only a few hundred people. Compared with now openly challenging a huge country

Compared with tens of millions of high school students, the latter is obviously more satisfying than the feeling of overcoming all dissatisfaction.

When the foreign audience heard this, they cheered and cheered.

Qin Ke also smiled and said to Ning Qingyun: "Study Committee, he reminded me. There are two IMO gold medals, a silver medal from the United States, and two gold medals from the American Mathematics League. If we beat them, it can be considered a defeat.

We have defeated countless high school math masters in the world, and we save trouble than they do. We don’t need a visa and don’t have to pay for air tickets. Thinking about it this way, don’t you think it’s more advantageous?”

The surrounding Xia Kingdom spectators had already been holding back their anger and depression. Ning Qingyun’s performance in the warm-up match had just greatly boosted their momentum and confidence. Now they heard Qin Ke’s witty words and felt even more cheerful.

They all clapped their hands and cheered.

"Come on God Qin, this competition will also be broadcast live on the live broadcast platform of the United States. If you defeat them, you can be regarded as giving Xia State a bad breath for the past ten years!"

"That's right, Qin Shen, we are optimistic about you! Teach them a lesson!"

Qin Ke raised his hand, and the surrounding area quickly became quiet. Qin Ke said: "Everyone prepares for a minute, and then it officially starts at 15:30."

Fernando had no objection. He communicated with his companions in a low voice for a while, then carefully selected five questions from the bottom of the prepared question bank and placed them on the large long marble table.

Qin Ke and Ning Qingyun also quickly took out their five questions.

As the hands of the huge wall clock in the lobby turned to 15:30, this mathematics competition that attracted the attention of countless high school students, even college students and ordinary people in both countries officially began.

Both sides' questions are written in English, which is actually a little disadvantageous for Qin Ke and Ning Qingyun. However, both of them have very high English levels. Qin Ke has reached the fourth year of junior high school and Ning Qingyun.

My English level is between CET-4 and CET-6, and the questions are not difficult to read.

For a moment, everyone in the entire lobby held their breath, fearing that making a little noise would affect the thinking of these seven people.

To the surprise of almost everyone, Qin Ke scanned the questions and chose one of the questions to give to Ning Qingyun. He picked up one of the questions and started writing it directly on the official answer sheet.

Countless people stared wide-eyed and almost wanted to remind Qin Ke that it was not a scratch paper. It was a formal answer sheet at that time. However, seeing Qin Ke's focused expression, the audience suppressed their words and only expected the person next to him to speak.

Ning Qingyun reminded Qin Ke.

But Ning Qingyun just glanced at Qin Ke's actions without any intention of interfering. She picked up her draft paper and started to work on the questions Qin Ke gave her. This made the audience watching the live broadcast and online

I was sweating all over, but in this situation, I could only comfort myself. Maybe Ning was afraid of interrupting Qin Shen's thinking, right?

On the other hand, some foreign spectators watched this scene with great interest, with mocking smiles on their lips. Apparently they thought that this high school student from Xia State was too nervous and mistakenly took the official answer sheet as a scratch paper.

The five American high school students opposite them all frowned after receiving the questions. Fernando watched for nearly two minutes before carefully assigning the other four questions to his companions.

Seeing that the five American high school students had solemn expressions, they were not at all relaxed and arrogant like the previous two days. After a while, they each picked up their pens and started writing on the draft paper.

Everyone was shocked, surprised, and confused.

Although the camera captured both sides' questions so that everyone could see Yangliu clearly through the screen, this was an all-English question, and it was too difficult. Many academic anchors who took advantage of the popularity and started live broadcasting were confused.

I was speechless and couldn't explain at all.

Everyone can only speculate that the questions Qin Ke and Ning Qingyun gave to five American high school students must be very difficult.

Looking at Qin Ke and Ning Qingyun, they both looked focused and calm.

The girl with a single ponytail has been calculating on the draft, but Qin Ke next to her continues to write on the official answer sheet that she "got by mistake".

The audience at the scene was even more anxious. They couldn't understand what they were looking at, and they didn't know whether they had the upper hand. Suddenly someone pointed at their mobile phone and wrote "Bilibili" in the void. Everyone was startled and put on their hands one after another.

Headphones, open the Bilibili APP on your phone.

Sure enough, there is a big promotional picture in the most conspicuous place on the homepage:

"This site specially invites Chen Licheng, the most famous genius college student in the mathematics community of Xia Guo, who is a doctoral student in mathematics at MIT, to explain the mathematics competition of five American high school students including Qin Ke, Ning Qingjun VS Fernando!"

Perhaps because he was afraid that audiences outside the academic circle would not know who Chen Licheng was, the promotional pictures also included a profile of Chen Licheng:

"Chen Licheng, a mathematical genius, won the IMO gold medal 13 years ago. While studying at Qingmu University, he won four individual gold medals, two silver medals, and two consecutive silver medals in the 'Master Qiu Mathematics Competition' including the individual all-around gold medal.

I won a special scholarship from Qingmu University in 2007, and was recommended to MIT to study for a master's and doctoral degree without taking the exam. I have now obtained a master's degree in mathematics from MIT, and will complete my doctoral degree next year and return to teach at Qingmu University."

MIT, Massachusetts Institute of Technology! The world's top university famous for its science!

Countless people were surprised and excited and clicked in without hesitation.

Sure enough, I saw a young man with short hair and good spirits in the live broadcast room explaining the current situation:

"Hello everyone, I am Chen Licheng. I am honored to be invited to explain this highly anticipated mathematics competition for high school students from the two countries. I have not paid much attention to Fernando and other high school students from the United States, but I am relatively familiar with Qin Ke.

I watched his last academic live broadcast at Station B and had a brief exchange with him. Later, I invited him to join my research team at Qingmu University next year. Unfortunately, he declined at the time. But overall, I am very fond of him.

appreciated."

"Okay, without further ado, let's take a look at the situation. After the warm-up match just now, the two sides have officially entered the '2VS5' competition. The rules of the competition are very simple. Within half an hour, who will win between the two teams?

Whoever solves the most questions will win. However, it should be noted here that according to international practice, the accuracy of the answers is also very critical. A small mistake that does not affect the final result will be judged to increase the answering time by 10%. If it exceeds

Three small mistakes, or one mistake that will affect the result, then the answer to this question will be invalid."

"Let's take a look at the five questions asked by both sides. The questions asked by the United States are very difficult. Everyone should know that IMO they are divided into DAY1 and DAY2, right? DAY1 and DAY2 have three questions every day and can be completed within 4.5 hours.

——Of course, I heard that this year’s IMO will be reformed. It will be changed to five questions on DAY1 and DAY2, and the time limit will be changed to 5 hours, which will undoubtedly increase the difficulty. Here we will first follow the old rules before the reform in previous years.

analyze."

"How difficult is IMO? Let me give you a rough difficulty level, which may not be very accurate. The difficulty level of our Xia National Mathematical Olympiad competition after this year's reform is around 9, while last year's IMO DAY1 questions had a difficulty level of 12

Around, the difficulty level of DAY2 questions is around 15. The difficulty level of the five questions just given to Qin Ke and Ning Qingyun in the United States is around 15. I guess these should be selected from the difficult question bank in the IMO special training in the United States.

Yes, they asked the five most difficult questions at once, and it seems that they really regarded Qin Ke and Ning Qingyun as strong rivals."

Hearing that the difficulty level reached 15, countless viewers who watched his live broadcast were dumbfounded. Even if they didn't understand the Mathematical Olympiad, they could still understand this simple number.

The difficulty level of this year's National Mathematical Olympiad was only around 9, but now the difficulty of the questions given by these five American high school students has almost doubled!

Did you make a mistake? Isn't it too shameful? Five big questions like this in a row? You know, in IMO, one question takes an hour and a half. How can you possibly do it in half an hour?

Even if Qin Ke breaks the historical record of the national championship, he will be helpless in the face of these five problems, right?

Some viewers immediately left a message anxiously asking: "What about the question Qin Ke gave the American students? Is it difficult?"

Chen Licheng replied: "I just took a look at the five questions on Qin Ke's side. The difficulty level is definitely not that exaggerated. There are about three difficulty levels around 13, which are slightly harder than DAY1. The other two are both.

Around 15. These questions are quite sophisticated, but I don’t know where Qin Ke got them from. I just checked the Internet and didn’t see similar questions. If he came up with them himself, that would be quite amazing.”

The audience didn't care about Chen Licheng's comments. They became anxious when they heard that the difficulty level was different, slightly lower than the questions provided by American high school students.

Originally 2VS5 was at a numerical disadvantage, but now the questions that one side has to do are slightly more difficult than the ones that the other side has to do - although it is only a little bit, it will undoubtedly further widen the comparison of the advantages and disadvantages of both sides.

But suddenly someone asked: "Huh? Master Chen, that's not right. According to what you said, Qin Ke and Ning Qingyun should be working harder on the questions now. Why, when I look at the looks on both sides, it's obviously the American side.

More careful and longer to think?"

Chen Licheng replied: "As I said just now, the questions provided by Qin Ke are very sophisticated. Even if the difficulty level is slightly lower, without flexible and careful thinking, it is very difficult to find the solution to the question... Hey, wait a minute.
Chapter completed!
