204.

In fact, Cheng Li almost had the idea of giving up just now.

You must know that Cheng Li is a person who never gives up easily, and he is an optimist who doesn't know what despair is. But even people like him will feel hopeless and almost have the idea of giving up.

One can imagine how difficult Riemann guessed this question was.

The Riemann conjecture is really too difficult, so difficult that people are completely confused and have no thoughts to solve it.

Famous conjectures such as the Hodge conjecture, although difficult, have already had some phased proof results, and some people have put forward some ideas to overcome them.

Or like Goldbach's conjecture, you can also get closer to the final answer step by step by proving a few weak conjectures, such as Goldbach's conjecture, which only proved "9+9" as early as 1920, and then approached "6+6......", "4+4", ...... "1+3" step by step...... In the end, the "1+2" proved by Chen Jingrun was only a stone's throw away from the final answer.

This kind of approaching the original conjecture step by step with a weak conjecture that is a little weaker than the original conjecture is also a very common solution idea in mathematics.

In addition, mathematicians will try to come up with a strong conjecture that can deduce the original conjecture to prove whether the strong conjecture is true, and then further deduce the original conjecture

However, whether it is a strong conjecture or a weak conjecture, it is completely unworkable for the Riemann conjecture.

As far as the Riemann conjecture is concerned, all the strong conjectures that can be used to deduce the Riemann conjecture are not valid, either they have found counterexamples or have been falsified.

Many of the weak conjectures of the Riemann conjecture have been independently proven, and the proof process cannot be generalized to the case of the Riemann conjecture.

This has led to the Riemann hypothesis being proposed for more than 150 years, and countless excellent mathematicians and mathematics enthusiasts have tried to solve the Riemann hypothesis, and they racked their brains, but none of them really proved the Riemann hypothesis. Not even some of the milestones.

Some of the original phased results of the proof direction are often proven to be dead ends in the end, and this road is not working.

In addition, the Riemann conjecture is too extensive and too important, so too many people want to prove the Riemann conjecture, and even many mathematicians and mathematics enthusiasts have spent their whole lives in order to prove the Riemann conjecture, but they can only be unknown and waste their years.

Therefore, the Riemann conjecture is probably the most desperate, if not the most difficult conjecture in the history of mathematics.

Therefore, Cheng Li never imagined that he would be able to solve the Riemann conjecture independently.

In his habitual thinking, this is simply a fantasy.

Let's put it this way, if someone on earth can rigorously prove the Riemann hypothesis, whether it is true or negative.

Then he can become a person who will leave a name in history, and he can win all the mathematics-related awards and achieve a grand slam.

His name will be sung alongside the greatest mathematicians of the planet, such as Gauss, Riemann, Euler, and others, and his name will forever be associated with one of the greatest achievements of human thought.

This is a supreme honor, but it is also a supreme difficulty.

Cheng Li subconsciously, he didn't think that his level of mathematics was comparable to that of a super-first-class mathematician.

He doesn't have that kind of consciousness himself, and my math level is already the strongest among the people.

However, in fact, Cheng Li's mathematical level, after the baptism of the 2999th layer of the arithmetic monument, and after the nourishment of the mysterious information, the mathematical level has already been improving by leaps and bounds at a speed that he can hardly imagine.

Therefore, he was able to independently prove the four-color theorem through the method of strict proof in the previous 2991 layers.

Although after Cheng Li proved the four-color theorem, he suddenly realized that his mathematical level was already so high.

But in such a short period of time, it is still difficult for him to adapt to his mentality all at once.

What's more, in the face of Riemann's conjecture, it has always been a pinnacle existence that makes him feel unattainable.

Therefore, Cheng Li felt desperate at first, and even came up with the habitual idea that he could not solve the Riemann conjecture.

However, when Xiao Shutong gave Cheng Li those cruel and bloody pictures of Qingling Island, he saw the helpless struggle of the people on Qingling Island in despair, and saw that even in the face of such a desperate situation, he still did not give up, and he still insisted at all costs.

Hold on and wait for yourself to go back with yin-yang arithmetic!

"He promised me that he would come back with the inheritance of yin-yang arithmetic! I believe him!" said the man in the picture.

There is also the decisive and tragic words of the Great Elder after taking the Infant Killing Pill.

"Just let me, this old bone, burn it again for Qingling Island in the end!

"Otherwise, if Cheng Li comes back and sees that there is no one who can resist on my Qingling Island, wouldn't it be for him to be a foreign person, let him be an outsider, and laugh at our Qingling Island for being soft bones!"

"Just let those Xuanjin sect thieves outside take a look at the last backbone of our Qingling Island!"

......

"Sons of the Green Spirit!

"There is still hope for us!

"For Qingling Island!"

......

Cheng Li looked at these pictures, and countless complex emotions were boiling in his heart.

"Hope...... Their hope is me, and the hope of so many people is all on me!"

Cheng Li felt a huge responsibility, which pressed on him, making him feel a little out of breath.

"They didn't give up, so how could I give up?"

"Since I'm on the 1000th floor, on the 2000th floor, and have chosen to move on, then I have no reason to fall on the 3000th floor now!"

"Otherwise, I will become a sinner! I will never forgive myself for the rest of my life!"

If Cheng Li had chosen to stop moving forward on the 1000th or 2000th floor, instead of coveting this arithmetic monument, then Cheng Li could have returned to Qingling Island with the Yin-Yang Arithmetic Inheritance as early as possible, and Qingling Island might not have been so miserable.

Therefore, Cheng Li couldn't help but take this responsibility on himself, and blamed himself for the current tragic situation of Qingling Island.

At this time, his heart was full of self-blame.

But now it is useless to blame yourself, and according to the rules of arithmetic tablets, there is no turning back.

Therefore, the only way to save Qingling Island at this time is to answer the question of the 3000th layer!

"Therefore, no matter how difficult this Riemann conjecture is, I must solve it and gnaw down this most difficult hard bone in the history of human mathematics!

"No matter what the cost!"

Cheng Li opened his eyes, there was no longer despair, confusion and self-blame in his eyes, all that was left was firmness and thinking!

He looked at Xiao Shutong and said, "How long does the Great Elder have left?"

Xiao Shu Tong said: "This Absolute Infant Pill usually only survives for 15 minutes after taking it. However, because of his relatively high cultivation, the Great Elder has already touched the threshold of transforming into a god. So I guess he'll live for 30 minutes. At this time, it had been 15 minutes since he had taken the Absolute Infant Pill, so he was afraid that he only had 15 minutes left to live. ”

"15 minutes...... If I pass through this layer, how long will it take to completely absorb the Yin-Yang Arithmetic Inheritance?" Cheng Li asked.

"Absorbing the inheritance of yin-yang arithmetic is very fast, because it is a Daigo empowerment style, although you can't completely digest the yin-yang arithmetic knowledge accumulated in Qingling Island for thousands of years at once. But this inherited knowledge will become the precipitation of information in your sea of knowledge within 1 minute through Daigo empowerment, and you will slowly digest it in the long days to come.

"However, if you just want to acquire the knowledge of one of the aspects of yin-yang arithmetic transmission, it is relatively fast, I estimate that it can be done in 1 minute.

"But if you pass the 3000th floor, then you can become the master of the Arithmetic Monument, then it will take some time to recognize the owner of the Arithmetic Monument, even if I help you with all my might, it will take at least 3 minutes. ”

Cheng Li nodded: "I know, that is to say, I have to solve the problem of the Riemann conjecture within 10 minutes, so that I can bring the inheritance of yin-yang arithmetic back to Qingling Island before the death of the Great Elder!"

Xiao Shutong expressed skepticism: "That's right, but the question is, are you sure you can solve this problem in 10 minutes? This is the key problem on the 3000th floor of the Arithmetic Monument, and the difficulty is not ordinary!"

Cheng Li said while setting a 10-minute countdown on the light sand.

"I know it's very difficult, and it's a bit overwhelming to say that it will take 10 minutes to solve the Riemann hypothesis. I'm afraid that all the mathematicians on the planet who have been fighting all their lives to solve the Riemann hypothesis may be so angry that they will come to me and beat me when they hear me say this. ”

No matter how hard it is, no matter how hard it is, I have to try it with all my might!

"I have a reason to do it!

"Even if I return to Qingling Island every minute and second at night, countless more people will die!"

"10 minutes is already the limit of what I can bear! If it weren't for my lack of ability, I would like to solve this Riemann conjecture immediately!

"If I can't return to Qingling Island within 10 minutes, I won't forgive myself in this life!"

"So, I must bring hope back to Qingling Island within 10 minutes!

"Let the Great Elder see hope before he dies and leave with hope!"
