Chinese 217. Just when the battle of Qingling Island entered the final white-hot stage, Cheng Li's battle in the arithmetic tablet also entered the final stage.

"Okay, after completing this step of proof, then I have strictly deduced the three-dimensional expression of the Riemann ζ function!" Cheng Li waved his fist hard, very excited.

He had succeeded in overcoming the most difficult fortress on the path of proving the Riemann conjecture!

"Then we are only one step away from proving the Riemann conjecture!

"That is to prove the three-dimensional expression of the Riemann ζ function, when projected to one dimension, the projection shape of its non-trivial zero point is exactly a straight line of Re(s)=1/2!"

All the solutions of the Riemann ζ function proposed by Riemann, i.e., the nontrivial zero point, are located on a certain critical line.

This is what the Riemann conjecture is about. Later research, and computers have calculated more than 10 trillion non-trivial zeros, all of which are on that critical line!

However, it has not been possible to figure out why all the nontrivial zeros of the Riemann ζ function are so precisely located on that critical line.

The proof idea of Cheng Li is that the Riemann ζ function is a three-dimensional version of the expression, and the shape of this three-dimensional version of the Riemann ζ function when it is projected into a one-dimensional plane by three dimensions is the critical line of Re(s)=1/2.

There are two most difficult aspects of this proof idea. One is to derive the three-dimensional expression of the Riemann ζ function, and only by deriving the three-dimensional expression of the Riemann ζ function can the next step be carried out.

The second difficulty is to prove that the nontrivial zeros of the three-dimensional expression of the Riemann ζ function are exactly distributed on the line Re(s)=1/2 when projected into one dimension.

As long as these two points can be rigorously proven, the Riemann hypothesis can be officially declared successful. Now that Cheng Li has proved the first point, the next step is to prove the second point!

For Cheng Li, as long as the first point can be proved, then the second point is not a big problem, he already has a complete proof idea!

He only needs time now to complete the second point of proof! However, what he lacks most now is time.

He glanced at the time and saw that there was only one minute left before the 50-minute countdown he had set!

Cheng Li couldn't help but be a little anxious, he assessed it a little, and it would take at least half an hour for him to complete the proof of the second point!

This is still a case of extraordinary performance, 1 minute, it is simply impossible. Cheng Li couldn't help but feel a little painful.

Before, when he saw no hope at all, it didn't matter if he had enough time.

Now that he had found a way to prove the Riemann conjecture, he was confident that he would be able to prove it if he was given a little more time.

And he has deduced the crucial, and most difficult, first point. It was the time of the most joy, and at this time to tell him, you don't have enough time, how can he stand it.

It's like when you write a math problem in the college entrance examination, when you are doing the last big problem, after hard thinking and meditation, you finally come up with a solution to the problem, and you have done half of the problem, and at this time, you look up and find that you are about to hand in the paper, how can you stand it.

So Cheng Li directly opened his mouth and shouted: "Little Arithmetic Boy, you come out for me!" Little Arithmetic Tong didn't know if he had already prepared a prank, and jumped out in an instant.

"Yo, Cheng Li boy, what are you calling me!" said Xiao Shutong's immature voice. Cheng Li asked directly: "Now there is only 1 minute left, is there a way to give me some more time?"

"Of course, there is a way to do this, I can temporarily ban the outside time for another 0 minutes. After Xiao Shutong finished speaking, he laughed happily in his heart: "Of course, it is impossible to do such a thing against the sky."

'The Arithmetic Tablet can adjust the flow rate of its own internal time, which is limited to its own range.

And if you want to stop the outside time, it will involve the time stop of the entire universe, which is too against the sky, at least the current arithmetic monument definitely does not have such a function.

Cheng Li didn't know this, and thought that the Arithmetic Monument really had such a function, so he hurriedly said.

"Then hurry up and stop it for me!" After finishing speaking, he also realized that such an anti-heaven function would definitely not be free of charge, so he added,

"How much does this cost?" replied, "No more, no more, you just need to deduct half of your life on the basis of the previous one." ”

"If you were a mortal with a normal lifespan of 100 years, you would have 50 years left after deducting half of it, and now you will only have 25 years after deducting half of it.

"Of course, because you are already a Qi Refining Stage cultivator, you can normally have a lifespan of 200 years. So in other words, if you were to activate this feature, then you should have 50 years of life left. ”

"If your cultivation can reach the foundation building stage, the golden pill stage, or even the Yuan infant stage in the future, your lifespan will naturally increase. It's just that the lifespan you will increase in the future due to cultivation will all be affected by these two deductions of half of your lifespan. After listening to this, Cheng Li thought about it for about two or three seconds, looked up and looked at the countdown for more than 40 seconds, and finally nodded: "I agree, please activate this function immediately." Xiao Shutong was very excited after hearing this, and he immediately waved his little hand, and once again took a green light from Cheng Li's body and submerged it into the monument.

In the end, after a light finger of the little arithmetic boy, the time on the countdown was frozen at 44 seconds, no longer beating.

It seems that in order to prove the persuasiveness of his words, Xiao Shutong also deliberately called up a light curtain. The above is just frozen, before Tuomu Zhenren retreated, and the three powerhouses of the Xuan Array Sect killed the Blood Clan Demon Monarch through a sneak attack.

"Well, you see, time has stopped outside. Cheng Li was pressed for time at this time, and he didn't have time to think about anything else, so he didn't doubt him, so he immediately plunged back into the nervous calculation.

"Okay, I see, now I'm going to continue to answer this question, please don't disturb me. Xiao Shutong looked a little aggrieved and said: "It's true, if you recruit me, you will come and go!" After speaking, he stomped his feet a little unhappily, and disappeared in place.

Then the next second, when he appeared in the mysterious space, he rolled on the ground and laughed so happily.

"Haha, this guy is really too naïve, so funny! I don't know what kind of expression he will have when he knows the truth, he really laughs at me Chinese!"
