The Polygnac conjecture belongs to the strong conjecture of twin primes, and for all natural numbers k, there are infinitely many pairs of prime numbers (p, p+2k). In the case of k=1, the twin prime conjecture exists, i.e., there are infinitely many primes p, such that p+2 is prime.

The latter has been proved in February this year by Lu Zhou's supplementary method of using topography to sieve method.

Prior to this, Zhang Yitang and other mathematicians had completed the study of the "bounded distance between prime numbers", and had completed the proof from 70 million to 246. These conclusions, all of which belong to the form of (P,P+2K), also provide strong clues for the proof of the Polygnac conjecture.

So far, the parts of "k=1" and "k=123、......、3.5X10^7" have been completed. Anyone with a discerning eye can see that this piece of the puzzle has been completed.

Now there is only one last step, which is to generalize "k=1" to "infinity".

If the twin prime conjecture only allowed Lu Zhou to be nominated for the Fields Medal in 18 years, then the proof of the Polygnac conjecture was completed, and winning the Fields Medal in 18 years was almost stable.

However, although it is easy to say, it is still difficult to generalize "K=1" to "infinity".

Methodologically speaking, this is a completely new job. The conclusion and proof process of the twin prime conjecture may only provide Lu Zhou with an idea. To prove Polignac's conjecture, perhaps he would have to pioneer a new method of proof, as he did at Princeton.

Even now that his math level has been upgraded from LV2 to LV3, it is difficult to complete the task.

And the worst thing is that the system limits the completion time, which is required before 16 years.

In other words, if you want to get the task reward, you must solve this problem within 15 years.

On the other hand, there is also a lot of randomness in the rewards this time. However, Lu Zhou felt that the twin prime conjecture had gained more than 40,000 experience, and this strong conjecture of twin prime numbers would not be lower than this number, right?

What's more, it's a bonus mission.

So, for this reward, he is still quite looking forward to it.

……

After receiving the task, Lu Zhou withdrew from the system space, fell asleep, and slept until noon the next day.

When I woke up, I found that there were five or six missed calls hanging on my phone.

Looking at the phone numbers, they were all called from Academician Lu's office, and Lu Zhou could guess that it was probably Senior Brother Yan who told Mr. Lu the news that he had returned to China.

Thinking that he would have to go to the old gentleman's office later, he didn't rush to call back.

Before lunch, he had one more important thing to do.

After crawling down from the bed and brushing his teeth and washing his face, Lu Zhou entered the system space again and clicked on the inventory.

[Scanner (disposable): It can perform a panoramic scan of the internal structure of an object with a volume scale of 1 cubic meter to analyze its structure and composition. 】

The introduction to the system is very brief, but Lu Zhou probably knows how to use this thing.

And, if used well, the power of this thing is simply unbelievable. It doesn't matter if you're a chip lithography machine or Iron Man's suit, if you shoot at it, all the technology inside will be cleaned up for you. As long as the problem of the production process is solved, it is no problem to rebuild one locally.

So the question is, what to use well?

"Can only be used once...... Don't even have a chance to test shoot? ”

Looking at the icon in the inventory, Lu Zhou felt a little entangled in his heart.

First of all, considering the maximization of returns, it is natural to use the samples rewarded by the system best.

In his inventory, there are three things in total. In addition to the "Wreckage One" rewarded by the system, there is also a "Nano Fitness Enhancement Needle with an expiration of two hours" that was drawn a long time ago, and a bottle of Sprite from the future.

So, he was faced with three choices.

One is a shot at Wreckage One, the other is a shot at the Nano Strength Enhancement Needle, and even a shot at Sprite is possible.

The first option yields materials from the remains of an unknown battery, but it's hard to say whether they'll be useful or not, and it's a mystery how much technology can be gained from that rag.

After all, he didn't even know what the core technology of that battery was, but he guessed through the task of observing the experiment of lithium dendrite formation that this battery was probably the legendary lithium-air battery or something.

As for the second type, it is a well-functioning sample and, according to the description of the system, the effect is strong and there are no side effects. If you can really reverse the technology in it, not to mention creating a batch of Captain America who are open, there should be no pressure on the transformation fighters of the level of the Winter Soldier...... Probably?

This is the last one, and it shouldn't be very difficult to make to get a recipe for a "future" drink...... At least compared to the first two.

After hesitating, Lu Zhou finally chose the former.

People still have to take a long-term view.

Although the direct economic effect of the third plan is very large, after all, the technical threshold is not high, and it is really delicious, but the development space is still too small. Moreover, it is quite difficult to protect intellectual property rights for this kind of thing that is not difficult to produce, and it is still difficult to rely on patents to feed up.

As for the second one, this technology is a bit sensitive, and although there is no doubt about its value, it feels like it is easy to go wrong in all aspects.

As for the first one, it's a bit like gambling.

It's hard to say what can be scanned out by the wreckage that has been destroyed like this.

"Can you only gamble?"

Reaching out and taking out the "Wreckage One" and "Scanner Gun" from the inventory, Lu Zhou closed his eyes and silently recited the system, exiting the system space.

Feeling the light and cold metallic texture in his hand, Lu Zhou put the broken battery on the table, then picked up the streamlined pistol, aimed at the broken battery and pulled the trigger.

Only a soft "buzz" sound was heard, and a blue arc flickered slightly at the muzzle of the gun, and a cone-shaped grid-like light blue light curtain bloomed in front of it.

The pale blue light curtain shrouded the remains of the battery, as if with a magical penetrating power, through the hard metal surface lightly, turning the pitch-black metal surface into a transparent color, and searching every inch of the shadow.

Looking at this scene, Lu Zhou's eyes straightened.

, it deserves to be the black technology of the system!

Just this metal-piercing beam of light arranged in a grid in space is at least a Nobel Prize-level discovery.

What a god particle, Standard Model, is so weak compared to this thing!

In the eyes of a layman, it may be nothing, it is just a ray of light full of science fiction, which illuminates a black thing transparently, but for Lu Zhou, an expert in mathematical physics, the existence of this thing simply subverts his cognition of high-energy physics and the Standard Model!

At least in the Standard Model, which he was familiar with, there was no particle that could explain the strange phenomenon in front of him......

At this moment, the scanning beam suddenly dimmed, and then it went out as if it had been cut off from the source.

The remains of the battery, which had been illuminated as translucent, had been repainted as if it had been repainted, restoring its previous metallic appearance.

The scanning gun in Lu Zhou's hand suddenly lost its weight and turned into a delicate black powder that slipped through his clenched fingers like grit. All that was left was a black USB stick, lying alone in his hands.

“……”

Spreading out his palms and looking at the USB flash drive in his hand, Lu Zhou didn't speak for a long time.

The scene in front of him seemed familiar, and he was not particularly surprised in his heart, but he had a little emotion.

This broken system really doesn't let him drill any loopholes.

If nothing else, the USB flash drive lying in his hand is mostly made of automatic degradable materials, and the data will be automatically decomposed or something after copying.

It's the same as the USB flash drive with Xiao Ai last time......
