The control group was torn apart by hand, and the four-year-old milk bag led the parents to countera

Ankang University has a special teaching method. The students are all geniuses from all walks of life, so they often compete with each other.

For this purpose, the school has specially set up an arena competition point. Students participating in the competition can ask the teacher to set questions, or they can set questions through the system.

The live video link of the competition will be sent to each student's personal account through the school's official website. Of course, if students are not interested in watching it, they can just click delete.

At this time, the competition between Youyou and Xie Fanqing in the ring was so great that the number of live broadcast viewers almost reached the highest level this year. Not only the students and teachers from the South Campus, but also many people from the North Campus came to join in the fun, and some even came to watch it live.

This also includes Chang Wangshu, who happens to be back at school and has nothing to do.

……

In a small auditorium somewhere, Youyou and Xie Fanqing stood on both sides of the big screen. There were a lot of people in the seats below. The mentors of both players came over, and many teachers also came over to join in the fun, and they acted as referees.

Everyone wants to see Youyou’s strength.

After all, many veteran students who have been in school for decades have not reached B level, but Youyou, a little kid, has achieved A level as soon as he entered the school, and has even entered the core innovation group of the department.

The teacher in charge of setting the questions snapped his fingers: "Old rules, you compete in three games, best of three. If the players are not satisfied with the results of the game, they can apply for best of five."

After saying that, he motioned for the two of them to sit down and said, "The competition will start soon. The first question is basic mental arithmetic..."

Because Youyou had only entered school for more than half a year, for the sake of fairness, the two sides purely tested their talent in mental arithmetic.

The rules for the first question are very simple. Calculate all the numbers you have seen in the order of addition, subtraction, multiplication and division, and so on. Whoever calculates the result first in the end wins.

As soon as he finished speaking, numbers began to scroll on the big screen. These numbers flashed very fast, almost in less than 0.3 seconds, and all of them exceeded seven digits. Or a long number with seven digits after the decimal point, the kind that if you blink your eyes a little, you'll miss a string of numbers.

The process should last ten minutes - after all, this is a mental arithmetic competition, not a cross-eye exercise, so there will be a two-second rest every minute.

However, the further you go, the more numbers appear, and some need to solve the square root first, with symbol interference in between.

On the stage, Youyou and Youyou stared at the big screen intently. The students watching the live broadcast also held their breath nervously, and the barrage was shot up:

[Although it is basic mental arithmetic, this is probably the most difficult level! 】

[Not only is it the most difficult, in an international mental arithmetic competition last year, the opponent asked a similar question, and the first place also took thirty seconds to solve it]

[I am looking forward to who of the two will win]

Because of their inherent impressions, most people felt that Xie Fanqing would win. The people present glanced at the innovation group sitting in the front row and saw that they all looked calm, as if they didn't care about the competition on stage at all, and they became uncertain for a moment.

Ten minutes passed quickly, the big screen dimmed, and the teacher who set the question snapped his fingers again: "Okay, now both sides start answering questions."

After the words fell, Youyou and Xie Fanqing said at the same time: "8546..." and added more than ten digits with decimal points.

The voices of the two fell at the same time.

Not only everyone watching the live broadcast, but also the teacher who gave the questions on the spot was stunned for two seconds, and then quickly clicked on the screen to call up the results calculated by the system.

The answer shown is completely correct.

The teacher who acted as the referee smiled and announced the result: [Xie Fanqing, Jiang Youyou...it took 0.5 seconds, a draw]

Youyou rubbed her sore eyes with a normal look on her face, waiting for the next question.

Xie Fanqing, who was opposite him, was not so calm. He never expected that Youyou could calculate it as fast as him.

Quickly start the next question, no longer basic mental arithmetic.

"The contestants randomly select 90 groups of 9-digit numbers, remember the selected numbers, and then find these 90 groups of 9-digit numbers from the sequence in sequence, subtract the found 9-digit numbers, and then follow the teacher's instructions Write the answer using the calculation method given..."

The calculation methods for this question no longer only include basic addition, subtraction, multiplication and division, but also include opening root squares of functional equations, etc.

Some students from the North Campus started to feel dizzy just after hearing the rules.

After a three-second countdown, the game begins. 90 groups of 18-digit numbers appear on the big screen, and Yuyou and Youyou must pick out 9 digits from each group within three seconds.

Then the big screen turned and the countdown started again. After three seconds, rows of numbers scrolled across the screen. These numbers scrolled past at a speed of 0.3 seconds. Youyou and Youyou needed to find the corresponding 0.3 numbers in these 9 seconds: and then subtract them.

But not every set of arrays can find the corresponding number. If not, go to the next set until you find it. This extremely tests the players' patience.

A stack of paper was placed in front of the two people. Different from the previous question, this question had to write down the solution process. After all, the 90 sets of numbers were randomly selected by the contestants. How could the answers be verified without writing them down?

Some people who are talented in this area also follow suit. However, compared with the basic mental arithmetic of the first question, this question is more difficult because it requires not only strong mental arithmetic ability, but also strong memory and keen reaction, even in special situations. There are not many students in the department who can take care of these points at the same time.

After about two minutes, the sequence of numbers on the big screen was still scrolling, and Xie Fanqing took the lead in picking up the pen.

Until several seconds passed, Youyou was still staring at the screen with her big eyes open.

The outcome seems to be clear at a glance. After all, every second in this genius-level game is precious. After another ten seconds, Youyou finally picked up the pen, lowered his head and wrote without stopping.

This was thanks to the fact that she often helped Tao Ping'an copy homework when she first went to Building No. 3. Improved my writing speed.

The question this time was too long, and I filled five pages of paper. After finally writing the answer, she put down the pen, rubbed her little arms, raised her head and said:

"Teacher, I've finished writing!"

After speaking, she looked towards the audience and saw many people staring at her dumbfounded. She blinked her big eyes in surprise, turned her head and saw that Xie Fanqing was still writing.

Feeling that she was staring at him, Xie Fanqing's hand holding the pen shook violently and his face turned red. After almost ten seconds, Xie Fanqing finally put down his pen.

The answers and calculation process of the two people were projected on the big screen.

Several referee teachers first checked the 90 sets of numbers, and both of them were completely correct. Then they used the system and manual assistance to calculate their answers to the questions, and they were also completely correct.

In this case, it depends on who can answer the questions the fastest.

Count from the moment you pick up the pen until you put it down.

Xie Fanqing took 11 minutes and 1 second, while Youyou took 10 minutes and 20 seconds.

The referee teacher directly announced, "In the second round, Jiang Youyou wins!"

As soon as the words fell, bursts of applause broke out from the audience.

Xie Fanqing was stunned in disbelief. He had been conceited and smart since he was young, and everyone praised him as a mathematical genius. For so many years, he had never lost in a competition among his peers, and he never thought that he would lose.

But today, he just gave this book to a five-year-old girl!

This reversal was not expected by the students watching the live broadcast, but there was still a martial arts fanatic from the North Campus who said:

[The difference between the two is only 40 seconds, almost a draw! 】

A student from the South School immediately retorted: "You can't say that. Xie Fanqing's dictation speed was much faster than Jiang Youyou's in the beginning. This is normal. After all, Jiang Youyou is only five years old and her bones are still developing. With so little strength, one can write so fast! 】

[And Xie Fanqing is already a fourteen-year-old boy, and his arm strength is naturally much stronger than Jiang Youyou. From this point of view alone, I think this game is unfair.

But Jiang Youyou won in the end! We can clearly see that when Xie Fanqing reached the middle of writing, his speed slowed down significantly, and there were several freezes at the end. On the other hand, Jiangyouyou maintained a constant speed from beginning to end,]

This shows that Youyou is confident about the answer.

In the luxurious lounge, Chang Wangshu stared at the live video and couldn't help but follow the calculations.

However, only halfway through the calculation, she was forced to interrupt because she remembered a few columns of numbers incorrectly, and she pursed her lips with an ugly expression.

Her arithmetic talent is indeed good, but she can't compare with Xie Fanqing, let alone Youyou.

At the competition site, it was now the third round that was crucial to determine the outcome.

The third round of questions chose a piece of calculation data during the manufacturing and development of a certain large-scale ordnance weapon. For the sake of fairness, the algorithm involved in the set of data intercepted by the teacher who created the question was learned by both of them.

Both parties must give the correct answer within three seconds.

The big screen flashed again, and almost three seconds passed. Youyou immediately picked up a brush and wrote down the answer.

On the opposite side, Xie Fanqing took ten seconds to pick up the pen. Regardless of whether his answer was correct or not, he had already lost this round.

Amidst the applause, the referee teacher announced: "In this competition, Jiang Youyou wins..."

Before he finished speaking, Xie Fanqing stood up suddenly, "Impossible, how could I lose..."

The referee teacher frowned: "Classmate Xie Fanqing, if you are dissatisfied with the result of the game, you can apply for another match!"

Xie Fanqing paused, clenched his fists, turned around and stared at Youyou: "I want to compete with you again!"

Youyou shook her head and refused: "No, I have to write so many words, it's so tiring!"

Xie Fanqing almost thought she was ridiculing him, but when he lowered his head and looked into the little guy's big, clean eyes, he pursed his lips and felt more embarrassed than ever before, but he still said:

"You don't need to write," she said, grabbing a pen and paper and writing a long list of numbers and symbols: "This was the final question in my exam last month. It took me ten minutes to solve it."

Youyou picked it up and glanced at it. Immediately below, a student shouted, "It's not fair, bullying the little girl..."

Xie Fanqing stared at her closely, his face so ugly that he almost flipped the table and left: "I'm not that mean. Don't worry, although this question is difficult, the content involved is all what you have learned..."

However, before he finished speaking, Youyou had already put down the paper and raised his head, and directly said the answer: "82mμm..."

It took less than a minute,

Xie Fanqing, who was still dissatisfied at first, felt like a balloon being popped. He took a step back with a pale face, as if the world had collapsed.

He took out the secondary card and put it on the table, then turned around. He strode out with his head down.
