Later, the people who asked the questions became hasty, and the questions they had prepared were often preempted by others, and they had to find another topic again.

But there are so many problems that can be found on the Internet, and it is too normal to encounter duplicates.

Some people just choose a good topic and are always asked first, and his previous questioner asked him the last topic he found, and for a while he couldn't find the topic at all, so he had to give up helplessly.

Next, more and more people began to give up, and some people found strange problems from remote places, and even calculated the probability of logic problems and raised them to Zhang Qi.

Some people even simply ask Zhang Qi the problems they encounter in their lives, for example, there is a lottery player, just ask Zhang Qi, if he buys a set of numbers every time, what is the probability of winning.

After Zhang Qi calculated, he regretfully told him, whether he bought it repeatedly or bought it with a different number, the odds of winning the lottery were pitiful. The difference is almost negligible in terms of exponential probability.

After asking most of the people, only about 20 minutes have passed.

The staff looked at the time and offered to let him take a break so that everyone would have more time to prepare for the problem, but Zhang Qi did not accept it.

His reasons are also very good, it is only eleven o'clock, and it is still far from twelve. He wanted to solve the problem and go home and eat again.

There is no way for everyone to do it, after all, no one can stump him.

Soon it was Yun Feiyang's turn, and he brought up the calculus problem that had been bothering him.

Zhang Qi only thought about it for a while, and then replied: "This question is beyond the scope of high school knowledge points and does not meet the rules. ”

Yun Feiyang heard him expose himself, and there was an embarrassed look on his face. Those who don't know must still think that he is making things difficult for Zhang Qi.

"I know it looks like a high school student can solve it, but it's actually a calculus problem in advanced math," he says. I just want to see, do you have any good ways to solve it? ”

Zhang Qi's brain is not a real computer after all, and it is not a simple series of simple numbers, and he can enumerate them one by one. But there is no way that he can calculate a completely endless sequence of numbers like this with his brain.

High school textbooks teach calculus, but there are very few and only brief descriptions of the definitions and operations of limits and derivatives.

He is not really a mathematical genius, and there is no way to create his own mathematical tools and mathematical formulas to solve such problems. Without a calculation method, he couldn't figure it out.

He could only say regretfully: "I haven't studied high mathematics, and I have no idea to solve the problem." ”

Yun Feiyang also felt very regretful.

Although Zhang Qi did not answer this question, everyone did not think that he failed in the challenge, after all, the rules have long been proposed, and the topic should be limited to the scope of high school knowledge.

Liu Shuyan, who was sitting behind Yun Feiyang, rolled her eyes, as if she had thought of a good idea.

Immediately it was her turn to ask questions.

She stood up and said a question in a cold and arrogant tone.

This is another calculus problem.

After Zhang Qi heard this, he said coldly: "Don't you know the rules? Someone has already asked about calculus before, and even if you ask it, it's against the law. ”

"Hehe, you don't have knowledge yourself, and you still say that I violated the rules?" Liu Shuyan felt very ridiculous, "This is a question for high school students, how can it go beyond the knowledge points of high school?" ”

Zhang Qi replied: "This is calculus in high mathematics, I don't read much, don't fool me." You said this is a question for high school students, but where did it come from? ”

"Olympiad." Liu Shuyan replied coldly, "Do you think the question of the high school math Olympiad is beyond the knowledge points of high school?" ”

Zhang Qi sneered and said, "Am I here to take the Olympiad?" It's ridiculous, I refuse to answer your question. ”

"Hmph, don't you dare to answer, right? What can you do if you don't have the ability?! If you have the ability, you can answer! Liu Shuyan was very proud, the topic she chose, in the International Olympiad Competition, stumped many high-achieving students, and those students who were sent to Beijing University and Peking University also fell on this topic. Even Liu Shuyan is no exception, she only knew how to answer the questions after listening to the national team teacher who led the team and the professor of the mathematics department of BGI to analyze the questions. Despite this, she still has a vague idea of the solution idea, and there are a few steps that she doesn't know why she did it.

She is completely sure that Zhang Qi will never be able to answer this question.

Zhang Qi waved his hand lightly: "Next." ”

Liu Shuyan hurriedly said: "Don't, you haven't answered my question yet!" Aren't you the perfect winner? If it's amazing, just answer it! Those high-achieving students who participated in the Olympiad could not get a full score, but you could get a full score, but you could not answer the Olympiad questions? Do you think people will believe it? Or is your perfect score simply a fraud and an unknown source? ”

Zhang Qi emphasized again: "I'm not here to participate in the Olympiad, so there is no need to answer your question." ”

The staff couldn't listen to it anymore, they had a good impression of Zhang Qi, but they didn't have a good impression of Liu Shuyan, who had been messing around, and they still favored Zhang Qi in their hearts.

They said, "Please don't make a noise, the rules clearly state that you can't exceed the high school knowledge points." As far as we know, some Olympiad questions have exceeded the knowledge level of ordinary high school students, so they can't be counted. ”

"Hmph, no matter what, if you can't answer, you're losing, you're going to challenge. Let's go back quickly, don't be embarrassed here. Liu Shuyan hugged her arms and sat down triumphantly, like a general who had won a battle, not paying attention to the words of the staff.

Zhang Qi didn't seem to hear her words, and said lightly: "Next." ”

There aren't many people left.

Next to Liu Shuyan, there were also those high-achieving students who were with her, and they stood up one by one, and said with an unkind face: "Aren't the Olympiad questions counted?" Don't dare to answer when you hear that it's difficult? Or are you not capable of doing it? The questions they asked before are all searchable on the Internet, but you can't find the Olympiad questions, right? ”

"We all think that only the Olympiad questions can see your true strength, please answer them positively."

Then they all asked about the Olympiad questions one by one, and the difficulty was not the ordinary kind.

Compared to those online puzzles, it is not a heavyweight at all. Some of the puzzles are also difficult because they are adapted from the Olympiad questions, but there are answers on the Internet, and they are not convinced.

The Olympiad questions they asked were basically not the last big questions in the previous Olympiad competitions, or they were additional bonus questions.

This kind of bonus questions, the general knowledge points are beyond the high school level, although it is said to be a bonus question, it is not a score question, and few people can get points. The difficulty is several times more difficult than the last big question, and even university professors have to think hard for a while when they encounter such a question.

Zhang Qi was very unhappy when he saw their attitude, and planned to end the challenge quickly, but he didn't answer them, just waved his hand and said: "I won't answer this kind of Olympiad questions that exceed the knowledge points of high school, the next one." ”

But the next one, it's still the Olympiad math question, and it's still not the last big question or a bonus question, and the difficulty is all top-level perverts.

After mentioning these people, the next crowd stopped asking questions, and abstained one by one.

Everyone can see that the meaning of the challenge has changed.

These people deliberately raised such a difficult topic to embarrass Zhang Qi. And Zhang Qi did not answer, which made the atmosphere of the scene a little solemn all of a sudden.

After asking the last person, that person also chose to abstain, Zhang Qi looked at the time, it was only half past eleven.

His face was calm, and he didn't have the annoyed and angry look that everyone imagined, but stretched his waist lightly and said, "Heh, it's done, it's flashed, go back to eat." ”

As he spoke, he crumpled a piece of scratch paper on the table, held it in his hand, and walked towards the reading room. As he passed by the trash can next to the door, he gently tossed the scratch paper into the trash can.

After he left, the audience was a little stunned.

"And that's the end? Is this challenge won or lost? ”
