In the past two days, he has been studying the integrals in the panel's properties, and the preliminary conclusion is that consuming the credits can put the brain into a special overclocking state.

Comprehensively improve their abilities in all aspects, and assist in overcoming problems and completing research.

And the speed of consumption of points is directly proportional to the difficulty of the problem.

To put it simply, if a person is compared to a sophisticated computer, and improving the ability to think abstractly is a software update and optimization, then the brain entering an overclocking state is a comprehensive upgrade in hardware. Theoretically, as long as the number of points is enough, he can even keep his brain overclocked at all times.

Of course, the premise is that the body can support it.

After Xu Yun figured out the role of integrals, he was worried that overclocking would cause harm to his body, so he didn't experiment for a long time.

But now he figured it out.

Since the nature of the panel is to nurture him to grow, there is no need to be intimidated.

Just do it and you're done.

"I got a total of fifty points for completing the last mission, which should be enough to support me to make this grand finale." Xu Yun looked at the two digits in the integral column on the panel, and analyzed with some uncertainty in his heart.

But worry is worry, and he does not hesitate to act.

Immediately control the consciousness and click on the points bar.

A confirmation window pops up.

"Do you consume credits to turn on overclocking?"

As Xu Yun decisively turned on, his surroundings seemed to change in an instant, and he was in a vacuum, and he could no longer hear any noise from the outside world.

It was as if time had stood still.

All that remains is the final question of the conic curve.

I didn't have any ideas to solve the problem before, but now I have a lot of thoughts, and I even have a detailed motion trajectory graph in my mind.

In just a few tens of seconds, he thought of several ways to solve the problem.

And the process is extremely detailed.

It's a feeling that's better than copying an answer.

The key is that he not only mastered this problem, but also had a deep understanding of the problem of conic curves.

came back to his senses in the next second, and saw Xu Yun immediately writing hard.

"Using the correlation point method to find the trajectory equation, let the passive point coordinates P be (x,y) and the active point coordinates be (x0,y0)......"

……

Meanwhile.

The integral value is also declining at a steady rate.

Xu Yun chose a relatively simple solution, and quickly completed the entire solution process in the overclocking state, but he did not immediately end the overclocking of the brain, and gradually became obsessed with this feeling and wanted to solve the problems he had given up in front of him.

Just after glimpsing that the points on the panel were about to become single digits, the whole person suddenly came to his senses.

Busy took the initiative to stop overclocking.

"Points are depleted so quickly!"

In the time it took to do just one question, 36 points were consumed, which is destined to be impossible to turn on the brain overclocking frequently.

If you want to use this method to quickly improve your level, it obviously won't work.

"It's a pity."

Secretly sighing to himself, Xu Yun had to accept this fact, and at the same time think about how to maximize the use of points in the future, so as to avoid the wasteful behavior of anti-aircraft guns fighting mosquitoes just now.

After all, as you can see from the rewards of these tasks, it is not so easy to get points.

"There is still half an hour before the time to hand in the papers, but I can check the questions I have done again." Xu Yun looked up at the time and thought in his heart.

Just as he flipped through the test paper and was about to review it from the beginning, suddenly an indescribable hunger began to rush through his body from his abdomen.

Almost instantly, his right hand pressed against his stomach.

Rao is usually polite, and at this moment, he couldn't help but burst into a foul voice in a low voice: "I'll go!" ”

Under normal circumstances, prolonged use of the brain will lead to hunger, let alone let the brain enter this special overclocking state.

He should have thought of that.

But now is obviously not the time to think about this, if you don't replenish your energy as soon as possible, I'm afraid that he will faint from hunger and faint halfway, and become a campus legend that will always be spread in the third middle school. Therefore, he did not hesitate, and did not bother to inform Li Hui and immediately grabbed the roll and ran to the podium.

Su Yushan was correcting the test papers received from the key class, noticed Xu Yun's figure, temporarily stopped his movements and asked, "What's wrong?" ”

"Teacher Su."

"My stomach hurts so badly that I want to go to the bathroom." Xu Yun's face turned pale and he gave Su Yushan a reason.

It's mainly because of hunger that I'm so embarrassed, which is really unspeakable.

The point is that no one will believe it.

Su Yushan glanced at Xu Yun when she heard this, and after finding that the uncomfortable expression on her face was indeed not pretending, she reached out to take the test paper and nodded in agreement: "You go, even if you hand in the paper in advance." ”

"Thank you, Mr. Su."

After receiving the approval, Xu Yun suddenly felt like he was on the verge of amnesty, and a few breaths disappeared from the sight of everyone in the class.

Li Hui who watched it was called an envy.

"I didn't expect Xu Yun to have acting skills, but it's not righteous to run first!" muttered a few times very resentfully, and then lay on the test paper in a daze.

He didn't believe that Xu Yun had a stomachache, he ate the same meal in the morning, why didn't he have anything to do.

Obviously, I wanted to end the exam early in this way.

Su Yushan attaches more importance to the in-class exam, and does not allow plagiarism and early submission, otherwise how many people will there be in the class at this time.

Yesterday night, Su Yushan had a good impression of Xu Yun.

After she got Xu Yun's test paper, she did not put it aside, but gave priority to correcting it, but as time passed, her face became more and more serious, and she showed a little surprise from time to time.

Although he pretends to be calm on the surface, he is actually no less than setting off a stormy wave in his heart.

"It's almost done."

"The accuracy rate is not low, it doesn't look like it's scribbled."

"What?"

"Even the finale has been completely solved, how is this possible!"

Especially after seeing that the last big question was also answered correctly, he could no longer maintain his expression, and his eyes were full of incredulity.

Su Yushan knew Xu Yun's math level very well, originally she thought that Xu Yun would submit the paper in advance, and it was estimated that there were many questions that she would not have time to do, but the actual completion was very high.

Maybe she can explain this point with Xu Yun's relatively high talent in mathematics, but the conic curve problem of the finale has also been solved, which really surprises her, you must know that this problem is a headache for many students with excellent grades even in key classes.

Besides, she didn't remember that she had told Xu Yun about this type of question.

But after the shock, all that remained was joy, happy to have a talented student.

"Looks like I don't know enough about my own students!" Su Yushan wrote the score in the upper right corner of the first page of the test paper, and a smile appeared on the corner of her mouth.

Then he raised his eyes to look at the people below who were still bored and were still working on the questions, and suddenly a strong expectation suddenly appeared in his heart.

She wanted to know what kind of expression the people in the second class would have when they learned Xu Yun's score, maybe it could produce some positive stimulation and improve the good atmosphere of studying hard in the class.
