Although his mood was extremely complicated, after dinner in the cafeteria, while strolling around the campus, Xu Changshu still called Zhang Hongcai back.

"Hey, Xiao Xu, hello, hello."

The politeness revealed in the microphone that did not conform to the other party's identity made Xu Changshu feel a little embarrassed.

"Director Zhang, I'm sorry, I had the opportunity to talk to Dr. Qiao about that matter today, but I didn't ask about some things."

"Oh?"

"Mainly I think it may not be long before you have to come to Xilin again, why don't you talk to Dr. Qiao in person then?"

"What do you mean? What is Dr. Qiao's new achievements? ”

"Well, his doctoral dissertation is almost finished."

"Ph.D. dissertation?"

It is no secret that Qiao Ze has officially graduated from his bachelor's degree and is preparing to do a doctorate at Xilin University of Technology.

However, he had already decided on the topic of his doctoral dissertation, but he had not publicized it. After all, this is not in line with Qiao Ze's temperament. There is no need to go around talking about the achievements you have made.

Xu Dajiang won't talk about this kind of thing everywhere, and even explained it to everyone, don't spread it for the time being.

After all, the school has just started construction of the planned building of the Institute of Mathematics, and the foundation is still being dug.

So except for a few people who are assigned to the research institute, there are really few people who know about it.

However, since Xu Changshu already knew the news that Qiao Ze's graduation thesis was about to be completed, he didn't think it was a secret.

This kind of doctoral dissertation is no longer within the scope of ordinary dissertations.

If this is verified, if the Fields Medal is not given to Joser at the World Congress of Mathematicians in 2026, theoretical physicists around the world will probably not be able to stand it. Feed all the food to these physicists, and you can't give Qiao Ze up?

"What? Are you saying that your school has decided to invite me to defend my doctoral dissertation? ”

"It's not ...... However, I think there may be a lot of people who need to be invited. What you didn't know was that Josser's PhD dissertation topic was about proof of the quality gap. ”

"You're saying that dissertations address quality gaps?"

"That's right!"

After a simple conversation, there was no sound on the other side, and Xu Changshu knew that it was not that the connection was broken, or that the signal was not good, but that the other side was so shocked that he didn't know what to say.

Actually, he's the same.

He still couldn't figure out how Qiao Ze could do it so quickly.

From proving the existence of the Yang-Mills equation, to finding the general solution to the equation, to now almost having completed the proof of the mass gap hypothesis, it has been less than four months. Even if it takes some time, it will be four or five months.

By the way, he also proposed supercoiled space algebra and transcendental geometry, which can be said to be two completely new mathematical research systems.

Whoever suddenly hears the news will probably be shocked and speechless.

Unless you don't understand the difficulty of this proposition at all.

This reaction from the other side even made Xu Changshu feel a little relieved. Because when he first learned the news, it was actually just as useless.

Sure enough, after a while, the other side muttered: "So you said that Dr. Qiao's thesis is almost finished, which means that this proposition is going to end in his hands?" ”

Xu Changshu hesitated for a moment, but added: "Actually, it's more than that. Today José talked to me about his general idea of proof, in which he not only found the non-zero minimum energy level that could exist, but also gave a formula that could be adjusted. ”

"Hmm...... All right...... Dr. Joe...... Forget it, looking back now, the biggest mistake I made last year was that I went to Xilin that time and didn't tie Qiao Ze back to Yanbei. Hehe, but who would have thought that? Right? ”

Xu Changshu didn't answer this, mainly because it was obviously a whisper, and he couldn't answer it.

"Forget it, there's no point in talking about the past. I see, thank you for the message. ”

"Director Zhang, you're welcome. Then I'll hang up first? ”

"Okay, you're busy. Get in touch if you have something. ”

"Well, goodbye."

……

After hanging up the phone, Xu Changshu didn't want to go back to the research institute for a while, let alone go back to the dormitory.

I don't even want to think about math in my head.

This is probably the common problem of all research-oriented scholars after contacting Qiao Ze for a period of time, and suddenly I feel that the career that I planned to fight for a lifetime seems to be the same with me and without me.

Thus casting doubt on everything that he is holding onto.

At this time, Xu Changshu was probably immersed in this emotion, "Am I too wasteful?" ”

In fact, many children who are admitted to Yanbei Academy of Mathematics with their ability will experience similar confusion.

The people around you who are too good often bring great pressure.

It's a pity that Xu Changshu was once known as the golden second generation of Yanbei Academy, and he was the only one who brought pressure to others before, and he really didn't feel how much pressure his classmates around him brought him, even when he was studying abroad.

But now that he finally experienced this feeling, he was really at a loss for a while.

After wandering around the school aimlessly, when he walked to the playground, he suddenly saw a familiar figure hurriedly walking past him.

"Professor Li?"

Li Jiangao subconsciously stopped, looked at the sound, then smiled, and responded: "Professor Xu, I'm sorry, I didn't pay attention just now." ”

"It's okay, it's okay." Xu Changshu hurriedly said.

Speaking of which, he didn't have the confidence to show his superiority in front of this professor.

In fact, there are probably few people in the entire academy who can pose in front of Li Jiangao.

However, what makes Xu Changshu sigh is that even though he has now become the most fragrant bun in the college, Li Jiangao's attitude towards people is still similar to that of an ordinary professor. is just the opposite of Qiao Ze, which can make people feel like a spring breeze.

"Just finished eating?"

"yes." Li Jiangao smiled and raised the lunch box in his hand.

Xu Changshu hesitated and said, "Well, are you busy?" If you're not busy, let's just talk? ”

"Yes. How? Got a problem with your research? ”

Although Li Jiangao was a little surprised, he nodded in response, and then walked together with Xu Changshu.

"It's fine. By the way, did José tell you? Is his dissertation almost finished? ”

"Well, you mentioned it to me on WeChat." Li Jiangao nodded.

In fact, Qiao Ze didn't plan to mention this matter to Li Jiangao before the paper was completed, but Li Jiangao definitely had to tell Qiao Ze when he changed WeChat, and after receiving Li Jiangao's WeChat, Qiao Ze simply reported the progress of the paper.

After answering, Li Jiangao suddenly realized the reason why Xu Changshu beside him was not in high interest at this time.

He seemed to have had this kind of emotion back then, so anxious that he couldn't sleep all night, and couldn't help but laugh again, so he took the initiative to speak: "Do you also think that Qiao Ze is doing this project too fast?" Before we could react, he was done? ”

"Well, I doubt that Qiao Ze's brain has been opened." Xu Changshu replied.

"In fact, it can't be said that Qiao Ze is doing fast, the main thing is that he has accumulated a lot." Li Jiangao thought for a while, and then comforted: "Let's put it this way, the day I first met Qiao Ze, he told me that he had been thinking about the quality gap for seven or eight years. So don't be too discouraged. ”

From Li Jiangao's point of view, he really didn't want a professor like Xu Changshu, who was obviously extremely talented in the direction of number theory, to be hit by Qiao Ze and collapsed.

"He's been thinking about this for so long?" Xu Changshu said in surprise.

"Right? You don't know, he told me that day that he was almost thinking of the answer to this question, and it didn't take much time to solve it. At the time, I thought it was amazing, I thought it would take some time, who would have thought it would be so fast? But to put it bluntly, it's just the accumulation of time. ”

Li Jiangao smiled and raised his hand to pat Xu Changshu's shoulder.

I'm used to patting Qiao Ze on the shoulder, but I'm not too embarrassed to encourage Qiao Ze like this recently, and when I saw that Xu Changshu's mood was wrong, I subconsciously slapped it again.

However, Xu Changshu didn't seem to be aware of it, and just asked blankly: "Doesn't that mean that Qiao Ze was already able to understand the Yang-Mills theory when he was ten years old and began to study it?" I remember when I was 10 years old, I was in the sixth grade of elementary school and I learned calculus. ”

"Huh?" Li Jiangao pursed his lips.

Well, at the age of ten, you will be in the sixth grade of elementary school? Shouldn't it be in fourth grade? And did you understand calculus in elementary school?

Of course, that's not the point.

Mainly, this enterprise-level understanding makes his well-intentioned persuasion seem to be counterproductive.

Well, he can't be blamed for that, it seems that everyone has to go through the hurdle in their hearts after all.

But then again, a ten-year-old guy who can learn calculus thoroughly should be able to figure it out, right?

So in the next company, Li Jiangao talked a lot less, until the two finally glanced at each other, and then said goodbye tacitly.

Just separated from Xu Changshu, less than two minutes later, Li Jiangao's new number rang.

took out his mobile phone and took a look, Li Jiangao felt a little surprised.

I just changed my number, why are there strange calls coming in? Or a landline?

Never mind...... Let's take it.

"Hey, hello, is it Professor Li Jiangao of Xilin University of Technology?"

"Well, I am, may I ask who you are?"

"Hello Professor Li Jiangao, my surname is Bi, my name is Bi Yuefeng, I am the director of the Office of the Science and Technology and Quality Department of the GF Science and Industry Bureau, I want to talk to you about something, is it convenient for you now?"

"Huh? ……”

……

On the third floor, when Qiao Ze decided to stop his day's work, Doudou suddenly pushed him a special invitation from the mailbox.

Qiao Ze probably skimmed through the email.

The sender is shown to be from the Commission of Science and Technology.

I hope to invite Qiao Ze to work with Li Jiangao to help a large group of UAV arrays called "Mantianxing" project design a multi-modal perception system.

Just looking at the requirements, it's quite a lot.

In addition to the most basic stability, easy maintenance, and extremely high reliability, it is also necessary to be able to independently correct the possible attacks or spoofing of drone sensors, so that the system has the ability to resist attacks and jamming.

The most important thing is that this system should be able to control and command a swarm of thousands or more drones at the same time.

It is said that this is an important scientific project, because the Science and Technology Commission has noticed the ability of Qiao Ze and Li Jiangao in artificial intelligence system design, so it is hoped that the two can independently carry out system design.

If the final design of the system is adopted, it will not only reimburse all research expenses, but also award the title of Outstanding Contribution Scientist to China.

Well, if you don't believe in Doudou's online judgment ability, this letter is indeed sent by the official mailbox, just looking at the content, I feel a little like a liar.

Qiao Ze was still thinking about how to reply to the letter when Li Jiangao's phone called.

"Qiao Ze, have you received an email from the Science and Industry Bureau?"

"Hmm."

"I just got a call too."

"Oh."

"This is the ...... What do you think? ”

"It's not interesting, is Uncle Li interested?"

"How do you say this? Listen to the meaning on the phone, if you agree, there will be someone to talk to us about this matter, and there will be professional engineers to cooperate. However, I think that even though they are asking us to work on this project, they actually want you to do it. So my opinion doesn't matter, what do you think? ”

"I think we can talk about it, but it's not the system."

"Huh? What do you mean? ”

"The swarm UAV multimodal system is not interesting, but it can challenge the design of a set of swarm multimodal perception unmanned operating system for the deep navy."

"Unmanned underwater swarms? It's too difficult, isn't it? Missions in the deep sea require long lurking hours, right? How to replenish energy during the period? The problem of underwater communication is not easy to solve, right? How to deal with navigation problems? ”

"There are many problems, but most of them can be solved. Most of these problems can be solved by making good use of sensors, and swarm collaboration can be solved by artificial intelligence technology, so that individuals have a higher ability to make autonomous decisions. It is just that high-intensity simulation training of underwater multimodal models is required. As for other issues such as energy and materials, they are not on our minds. ”

"What do you mean?"

"If they are willing to invest more in an unmanned underwater swarm, I am willing to help design this multimodal system. Swarm UAS are not challenging. ”

"That's right...... Then you can do it. ”

"Hmm. Uncle Li, did Dean Xu contact you today? ”

"No, what's wrong?"

"Tomorrow at about two o'clock in the afternoon, there will be two mathematicians in the capital to visit, are you coming?"

"This ...... I'm still not going, am I? ”

"Oh. Good. ”

……

After hanging up Li Jiangao's phone, Qiao Ze began to reply and quickly sent his thoughts out.

He even helped him think of the project's code name - "Deep Sea Ghost Swarm".

It's really not fast this time, mainly because he has really thought about this question recently.

After all, I have studied some geological features in my spare time, and I always have something to gain.

In addition to completing the functions of reconnaissance, mapping, positioning, etc., a large-scale underwater unmanned swarm may be able to help my father-in-law fulfill his wish one day in the future.

This is just one of the scenarios that Qiao Ze has in mind.

Coincidentally, someone came to the door and was able to try it.

It doesn't matter if it's not adopted, there's no loss anyway, it's nothing more than both sides tentatively drawing a big pie for each other.

Speaking of which, the timing is perfect.

Because after the completion of his doctoral dissertation, Qiao Ze planned to take a break for a while.

If the other party is really willing to invest, he can just use this transition time to build this system.

It's probably a win-win, right?

……

There was something going on, and when Qiao Ze called Su Mucheng, who was tired of downstairs, to go out, it was an hour later than usual.

But at ten o'clock in the evening, it is the time when the school is lively in the evening.

It's not yet exam season, and those who study on their own have already come out of the teaching building, and those who want to eat supper are also calling friends out at this time.

As soon as he walked to the front of the brightly lit Gong 2 teaching building, a gust of cold wind blew, making Su Mucheng subconsciously shrink his neck.

It is still very cold in Xilin in February, although the weather is good during the day, but at night, the temperature is still in the single digits.

"Hey, Brother Qiao, this weather ......"

Su Mucheng was talking, when he suddenly found Qiao Ze stopped, looked across the road and didn't know what to think.

“…… It's cold, do you need a scarf? ”

"Well, no. You wait here. ”

"Oh, what are you going to do?"

"It's a little thing."

With that, Qiao Ze walked directly to the opposite side.

……

Across the road in front of the school building, two men were walking side by side.

"Old Lu, that guy seems to be coming towards us?"

"No matter, don't look, go straight over."

"Hmm."

There was nothing wrong with the hasty response plan, but Qiao Ze still stopped directly opposite the two.

This is somewhat surprising.

"Is there something wrong?" The handsome guy who looked younger asked in some surprise.

Zhou Shun felt that his adaptability in the face of emergencies was still very strong, at least he asked naturally.

And then the guy on the other side who was too young made him break the defense with a word.

"Protection or surveillance?"

Look at this question, not only does it save the subject, but it doesn't give them more choices.

Fortunately, this guy who is not good at words next to him took the topic over.

"What do you mean?"

Well, Zhou Shun found that Lu Nan was actually better at acting than him, and the stunned on his face was just right.

"There are three groups of people in a daily life, two by two, and they are very regular. Today you work late, no accident, tomorrow morning shift will be the right corner of the mouth with a mole and thick eyebrows and a deep nose bridge, the evening shift at this time will be a couple. There are probably three other people who have been in contact with you. Right? ”

Zhou Shun and Lu Nan glanced at each other.

For a while, both of them had no idea.

It's not a good place for a stalemate, with people coming and going. Wait, that naïve girl seems to be planning to come over too.

Qiao Ze waited for a moment and said, "Three seconds later, I'll ask someone." ”

"The main thing is to protect and make sure there are no suspicious people." Lu Nan said quickly.

"Oh." Qiao Ze immediately asked again, "Is it necessary here too?" ”

"We're just working, it's not up to us to decide whether it's necessary or not."

Qiao Ze asked quickly, and Lu Nan responded quickly.

"Oh." Qiao Ze nodded, accepting the explanation.

"How did you find out?" Zhou Shun couldn't help but ask.

"Normal observation, statistics and probability, plus logical deduction." Qiao Ze explained succinctly: "It's okay, I'm just making sure, you guys are busy." ”

After speaking, Qiao Ze nodded at the two of them, then turned his head and walked away, just in time to catch up with Su Mucheng who came over.

Then a few words of conversation drifted in the wind.

"Brother Qiao, who are they?"

"I don't know."

"Huh? Then you ......"

"Sure, but it's okay now. Do you go back to the dorm or not? ”

"Let's go home."

"Okay."

……

"Old Lu, what's the situation?"

"What do you say? Aren't you bored? Isn't that interesting now? ”

"No, how did they all recognize it? We've only been following for a few days? ”

"It's the thirteenth day."

"So what now?"

"Huh......" Lu Nan glanced at a young couple who had walked more than 30 meters, and said with a sigh: "Follow, the task must be completed." ”

As he spoke, he moved his footsteps directly.

Fortunately, this young man was not as difficult to deal with as he imagined, and he was very simple, at least he didn't directly let them get out, and it wasn't difficult to follow.

"Old Lu, how did you say he saw it? Probability and Statistics? What do you mean? ”

"I don't know, anyway, it's definitely not by hooking three strands, four strings and five." Lu Nan replied angrily.

"What do you mean? Pythagorean theorem? Zhou Shun was stunned and asked rhetorically.

"Or else? That's what I remember about the mathematical theorem. ”

"That'...... I still remember being negative and positive. ”

"Very good, you come to report tonight, and by the way, you also wrote the report, after all, you know more than me."

“…… Lao Lu, that Su Mucheng is looking back at us. ”

"Just look at it, what else can I do?"

"I didn't feel so embarrassed on my first mission."

"At least you don't complain about boredom."

……

"Brother Qiao, were those two people still following behind just now?"

"Shadows of the Deep?"

When a printed letter or a complete feasibility report is placed in front of the old man, people can't help but ask in surprise.

"José wanted to design an underwater set, huh...... According to what he wrote, it should be a deep-sea multi-modal unmanned swarm system. Of course, the premise is that we agree to continue to invest in this project...... However, the report he wrote was actually quite complete, and he also designed several sets of small deep-sea unmanned devices.

By the way, if according to his expected performance, this simulation system can support more than 100,000 underwater individual swarms to perform a variety of tasks in the future. Most of the comrades in the analysis section felt that this design was too advanced, and the investment was too high, and it was not very feasible. ”

"This kid is so good at tossing?"

"Not only can he toss, but there is also a report that he has basically completed the quality gap problem. Moreover, it is said that the method of proof is very advanced, but the comrades on the front line do not understand much about what is ahead. There is also a later part of this report. ”

"Okay, wait until I'm done, and then see if we need to hold an expert meeting to discuss it."

"Okay, old money."

……

Another department.

"All nine of them have been recognized?"

"Well, here's the report that Tinder submitted today."

"Huh...... You've seen it, look, this conversation, even has the face to ask how others found out? I'm starting to doubt the professionalism of these guys. ”

"This ...... You know, the Tinder Squad is already one of the most professional teams. That...... Why don't you change them? ”

"Forget it, does it still make sense? It's really not good, you just go and explain, go back and talk to the school on the phone, and let Principal Chen arrange it. ”

"Okay."
