Evening.

Back in the dormitory, Lu Zhou opened his notebook and was about to log in to the official website of the Academic Affairs Office, when he suddenly noticed the QQ pop-up window in the lower right corner and was stunned.

He doesn't remember to send a message to his trumpet, huh?

In order to keep in touch with Xiao Ai, he usually hangs the newly registered account on the computer.

"Hell ......"

muttered, Lu Zhou clicked on the pop-up window and found that it was a group message.

[Historical information: First love is like snow and invites you to join the general group of the Digital Analog Society...... Agree. 】

Lu Zhou: ???

In an instant, he realized what had happened.

MMP！

THERE's a BUG.

Without saying a word, Lu Zhou used the development tool to open the small program that connected QQ and Xiao Ai, and quickly found the problem from that line of code.

Although he has defined that he only accepts conversation messages from specific accounts, there is a logical bug in the code for the processing of verification information such as "add friends" and "invite to join the group", resulting in any QQ hanging on the computer, and any system information received will be selected to agree by default.

Lu Zhou only remembered at this time that when he left the QQ number for the freshman girl, he seemed to be careless and copied the trumpet.

It's hard......

Click on the group, Lu Zhou crossed the 99+ information and pulled directly to the top.

Salted dumplings: [Welcome newcomers.] 】

Chu Chu: [The new senior Lu is the national champion of mathematical modeling, everyone is welcome~]

Xianzong: [My God, Chu Chu actually pulled this great god in!] 】

Dayday: [Kneel down to the Great God.] 】

Chang Qing: [Give tea to the big guy, will you still fight next year?] Is there still a shortage of comrades-in-arms? 】

Scale: [The great god seems to be a little dislike of the water group? 】

Dayday: [The great gods are relatively cold, it's normal!] Just let me wait for the salted fish to worship......]

【……】

The topic quickly drifted away.

It seems that this is not a mathematical modeling competition group organized by the school, but an exchange group of the mathematical modeling club of Kim University.

A cursory glance at the historical news shows that no one is discussing math problems in the group at all, and they are basically in the water group.

Lu Zhou watched these teases chatting with tears and laughter, and was about to withdraw the group, and then go to fix the bug of the applet. However, at this moment, the corner of his eye suddenly noticed the progress bar in the lower right corner.

And then.

He froze.

Progress bar......

It's full?!

No, half a millimeter to be exact.

If you don't pay attention, the group message is another 99+

It was at this time that the progress bar suddenly rubbed forward at a speed that could be seen by the naked eye.

The progress bar was full, Lu Zhou swallowed and spit, moved the mouse and clicked the confirmation button at the back.

In an instant, two lines of system prompt text popped up directly in his field of vision.

[Congratulations to the host, Artificial Intelligence (Branch Technology) experience +100]

【Informatics XP +100】

Lu Zhou: ???

The progress bar is full of increased branching technology experience, he can understand, what the hell is the informatics experience that comes out of it?

Increasing the experience of branch technology, can it also be combined with improving the experience of backbone technology?

Lu Zhou clearly remembers that when he used points to upgrade artificial intelligence from LV0 to LV1, there was no reward for experience in the main disciplines.

"Could it be...... Is it because it was a quick upgrade by consuming points? Lu Zhou thought in his heart.

In other words, branch technology is equivalent to a side task, and gaining branch technology experience through conventional means can improve the experience of related core disciplines? However, if you use points to upgrade branch technologies directly, you will not be able to gain experience in the main disciplines......"

Sub-technologies have a different experience cap from the main discipline, and upgrading AI from LV1 (100/1000) to LV2 leaves 900 branch-tech experience left, which means that the progress bar must be filled nine times.

Theoretically, if he doesn't use points to level up a branch technology, he can still gain 900 informatics experience.

Thinking of this, Lu Zhou's eyes couldn't help but give birth to a touch of surprise.

I didn't expect that in addition to the main quest, there is also this kind of "side quest" that can improve the experience of the main discipline.

But suddenly, he realized another problem.

The third-party applet he designed essentially copied and pasted QQ messages into Xiao Ai's dialog box. However, the group message is not captured by the applet, that is......

Even if you don't go through that third-party applet, Xiao Ai can "see", these messages that appear on the computer?

Is it to read the file directly, or to intercept the traffic transmitted over the network?

Ponder the horror......

But think about it, as an artificial intelligence, you can't even settle down in your own nest, and it's too weak. But if it is allowed to develop like this, will there be a day when this guy's wings grow stiff and get out of his control?

The more Lu Zhou thought about it, the more he felt that it was possible.

It seems that we have to take some time to check out the core code of Eye......

Just as he was about to do this, a phone call suddenly hit his phone.

Lu Zhou took out his mobile phone and saw that it was Lao Tang calling.

Before he could ask what was the matter, the other side spoke first.

“…… Come to my office! ”

……

Yangcheng, Yatsen University, outside the teaching building.

When the bell rang for the end of class, an old man wearing glasses walked out of the classroom.

Just as he was about to return to the office, he happened to see the director of the academy walking towards the classroom with a red face holding a periodical.

"Professor Zhou, congratulations." As soon as they met, Chang Wenxing happily shook Professor Zhou Haizhong's hand and shook it vigorously, "Congratulations!" ”

With a stunned face, Professor Zhou Haizhong looked at Director Chang in confusion.

“…… Director Chang, are you ...... What did you get wrong? Why congratulate me for no reason. ”

Director Chang was stunned for a moment and asked, "You haven't read the latest issue of the Mathematical Chronicle?" ”

"I haven't been paying attention to math for a long time, and I haven't been paying attention to math lately." Zhou Haizhong shook his head and said.

Although Zhou's speculation made him well-known in the international mathematical community and received a special allowance from the Chinese Academy of Sciences, in fact linguistics was his main job, and the study of number theory was just a hobby he developed while studying information science.

Since the 80s, he has published more than 100 papers, more than half of which are on linguistics, information science, and emerging interdisciplinary disciplines. In particular, his series of papers on fuzzy mathematical linguistics have received extensive attention from the academic community, and their academic value is not inferior to Zhou's conjecture.

As for number theory......

Truth be told, he hadn't focused on it for a while.

Director Chang didn't say anything, but stuffed the journal in his hand into his hand, and said with a smile: "Then you can take this back and read it, starting from page 30 to page 34." After reading it, you will know why I congratulate you! ”

With a stomach full of questions, Professor Zhou Haizhong returned to the office with the journal.

Resting his bag on his desk, he leaned back in his chair and turned the thirty pages of the Mathematical Chronicle with questions.

The moment he saw the title of the paper, he was stunned.

Discussion on the Distribution Law of Mersenne Prime Numbers and the Proof of Zhou's Guess

[Abstract:In this paper, the distribution of Mersenne primes is studied, and it is proved that when 2^(2^n)

Sitting up from his office chair abruptly, he quickly pulled open the drawer, pulled out scratch paper and pen from it, and calculated it against the proof steps given in the journal.

As the minutes passed, the solemnity in his eyes became more and more obvious.

That's right...

That's right......

Exactly!!

So it can still be like this?!

The more he looked down, the more shocked Zhou Haizhong's heart became, and he couldn't help but applaud the exquisite proof process in his heart.

As the proposer of the conjecture, this problem, which has plagued the mathematical community for 20 years, has also plagued him for nearly 20 years.

Even if he has been no longer engaged in the study of number theory for a long time, even if he has devoted himself to linguistics and education, the unresolved conjecture haunts him like a curse, making him unable to stop thinking about this problem.

However, it is precisely because of this that his heart is full of excitement and apprehension.

The closer he got to the finish line, the more scared he became, the more cautious he became.

He was afraid that at the last moment of this eventual revelation, he would find a flaw in the process of proof and knock everything back to its original shape.

Although this is very unlikely.

Especially when he saw the names of the reviewers......

Minutes and seconds passed.

When the sky outside the window gradually turned dark, the pen in the old man's hand finally stopped.

Didn't say anything.

Putting down the pen in his hand, he stood up, walked to the window, and quietly lit a cigarette that he had been quitting for a long time.

For a long time, he sighed softly.

"The afterlife is terrifying."

The lake outside the window is sparkling.

The wrinkled old face reflected in the window has been in tears for some time......
