208.

In fact, 5 minutes ago, the little arithmetic boy had already consumed his energy and activated the time flow rate change function of the arithmetic tablet.

However, he felt that he couldn't cheapen Cheng Li like this, so he decided to scare him.

Since it is a scare, of course, it will definitely not really cost Cheng Li half of his life.

It's just that Cheng Li at this time doesn't know all this.

He just thinks according to the logic of normal people's thinking, and it is indeed very reasonable to pay half of his life in exchange for using something as anti-heaven as the arithmetic tablet.

And because people in the arithmetic tablet will not notice that their time flow rate has changed, they will feel that everything is normal. So Cheng Li didn't know that at this time, the time in the arithmetic tablet had become faster, and the time outside had slowed down.

However, because Xiao Shutong had already turned off all the light curtains that could see Qingling Island, Cheng Li, who had no reference, didn't know that the speed of time had already changed.

Therefore, Cheng Li, as Xiao Shutong expected, really believed Xiao Shutong's rhetoric.

However, Xiao Shutong originally thought that Cheng Li would be entangled and think about it for a long time, and in the end he would even refuse, wasting a lot of time in vain.

However, almost only three seconds later, he heard Cheng Li's answer.

"I agree to spend half of my life to activate the time flow change function of the arithmetic tablet, please execute it immediately. ”

"Huh?"

Xiao Shutong looked at Cheng Li's very serious answer, and couldn't help but be stunned.

Originally, he wanted to tease Cheng Li, but now he was stunned.

If he wasn't very sure, Cheng Li would have believed it, and he would have thought that his little trick had been exposed.

"Are you sure? That's half life! And it's a permanent deprivation!"

Cheng Li nodded very affirmatively: "I'm sure and sure." ”

"The value of life is not in length, but in thickness!

"There's not that much time for me to waste right now, so please do it right away!"

Xiao Shutong looked like he was defeated by Cheng Li.

"Alright, then I'll fulfill you!"

Xiao Xuan looked angry and depraved, and then with a wave of his hand, he took out a green energy light cluster from Cheng Li's body.

After this green energy light cluster was taken from Cheng Li's body, Cheng Li did not feel any discomfort in his body.

It's just that the thought that this energy light cluster represents half of his lifespan, he is still a little distressed.

Then Cheng Li saw that Xiao Shutong submerged this green energy light cluster into the back of the monument, and a burst of light shone around him, and then he saw Xiao Shutong take out an hourglass and said.

"Okay, now the speed of time inside the Arithmetic Monument has been accelerated tenfold. ”

As if seeing Cheng Li's disbelief, Xiao Shutong directly waved out a light curtain, which showed the real-time picture of Qingling Island outside at this time.

"See, this is the real-time picture of Qingling Island now, from the inside of our arithmetic monument, they are like they are broadcasting slow motion, and they have been slowed down ten times!"

Cheng Li saw that this was indeed the case, and couldn't help but be even more shocked by this arithmetic monument.

"It is possible to control the flow of time, it is worthy of being a natural thing, and it is really high-end and high-end!"

Then Cheng Li looked at the countdown on the light sand, and Cheng Li went over to fiddle with it again, making the countdown 50 minutes.

"Okay, now that the flow of time has accelerated, now that I've got 50 minutes, I finally have more time to think. But to solve the problem of the Riemann conjecture, 5 minutes and 50 minutes, in fact, there is not much difference, time is just as short for me, I hope you don't interfere with me anymore. ”

Cheng Li immediately ignored the little arithmetic boy and plunged directly into the battlefield of the battle with Riemann's conjecture.

Xiao Shutong pursed his lips and said, "What a ruthless person, cross the river and tear down the bridge!"

After speaking, he really disappeared in place with a "snap".

Then in the next second, the little arithmetic boy appeared in the mysterious space of the arithmetic monument and shouted.

"Really, with his attitude, I have to give him another layer of BUFF, I feel a little aggrieved when I think about it. ”

Despite this, Xiao Shutong finally waved his hand and consumed his energy to activate the aura of the arithmetic stele.

In an instant, a hazy beam of light shrouded Cheng Li like a spotlight.

"Hmm, how can there be a light coming down?" Cheng Li said with some doubts, "Does he think it's a little dark, add a light to me?"

"It was a bit dim before, but now it's just right. ”

Cheng Li didn't have so much time to waste thinking about these side matters, and soon rejoined the battle against the Riemann conjecture.

I continued to think hard about myself.

As the thinking deepened, one idea after another was put forward by Cheng Li and then vetoed.

In this process, Cheng Li's thoughts became more and more divergent, and various ideas were stirring in his mind.

Unconsciously, Cheng Li felt that there were more and more thoughts in his head.

And the wonderful state of constant flashes of inspiration began to appear again.

As his brain became more and more active, Cheng Li felt that inspiration began to gush out like a spring, and for a while, Cheng Li's thinking seemed to be swimming in the vast ocean of mathematics, constantly thinking about one problem after another.

"My mind shouldn't be shackled.

"Since the earth has not come up with a solution to the Riemann conjecture for such a long time, it shows that under the existing mathematical system on the earth, there is a lack of some kind of tool that can solve the Riemann conjecture!

"So, I've been thinking about the futility of the mathematical tools that have been proposed. Countless people have already tried it, and if this can prove the Riemann conjecture, then the Riemann conjecture has been proven a long time ago!

"So I'll have to find a new way to devise a new mathematical tool to help me prove the Riemann hypothesis!"

Cheng Li's thoughts were flying, and he began to realize a core key issue, that is, he couldn't let his thinking be bound and restricted.

For a while, all kinds of whimsical ideas were whimsically come up with Cheng Li.

However, most of these whimsical ideas were finally proved by Cheng Li himself, which was indeed whimsical, and none of them could really prove the Riemann conjecture.

However, the expansion of such thinking has greatly broadened the scope of Cheng Li's thinking.

His thinking began to be not limited to number theory, but extended to every field of mathematics.

He tried to inspire himself from every field and corner of mathematics, to find the opportunity to solve the hidden problems of Riemannian geometry!

With the deepening of his thinking, Cheng Li couldn't help but have an admiration for Li Man.

"Riemann is really amazing, worthy of being the most creative mathematician in the history of mathematics!

He used the Gamma function ζ(s) to continue to extend the Riemann zeta function analysis to the entire complex plane. It showcases Riemann's keen intuition and great technique. ”

"His insight is truly amazing, and so is Riemannian geometry. Before Riemann, it was completely impossible to imagine that space could be curved and planes could be curved...... It is even more unimaginable that the revolution of the implicit geometric dimension has opened up a new field of geometric research......"

"Wait a minute!"

Cheng Li's mind suddenly flashed.

An incomparably important and critical word, after it appeared in the sentence just now, it was like a flame in his mind, it was so dazzling, it completely attracted all Cheng Li's thinking attention!

"I see! So the most critical problem is this! So that's it! Haha!"
