God's Crown

If An Yan continues at this pace, I am afraid that he will be able to graduate in June next year, or December at the latest.After he gave an academic report at Stanford, his paper will definitely be the first to be published in the journal.As a well-known scholar in the world, and still papers on physics, general academic journals will naturally selectively publish such papers to increase their own impact factors.

After all, these academic journals also have long-term plans for their own journals. A paper published by a well-known scholar can attract much more attention than several papers published by unknown scholars.Unless, like An Yan, there is some breakthrough in the research.From unknown deeds to minor fame or, more likely, academics of great academic stature.

Otherwise, when journals screen papers, they must first select well-known or fresh papers and send them to peers for review.

In this way, if An Yan's paper is written quickly enough, it only needs to be published in the middle of next year.Plus he picks a dissertation.Does this guy want to graduate in a year?Will it be a little too rushed?The professor originally thought that it would be too late to give An Yan free rein to write a thesis for two years.

After all, it takes time for submitted papers to be published, but the operation of An Yan made the professor a little at a loss.After teaching for so many years, this is the first time I have met such a student professor.As a freshman, he made a breakthrough in new energy materials that almost shocked the entire physics world and even the chemistry world.If someone had told him this before, he would definitely think it was a fantasy.

Ever since he met him, he was particularly shocked that such a thing really happened.A student who has just entered university, not only has good knowledge, but also can use such a great talent in research, it is almost as if God bestowed wisdom on him.Or it can be said that God opened the window called science for him.

Looking at An Yan's performance, the professor thought that it would be very easy for An Yan to surpass him in his lifetime.At least, after 20 years, the professor thought he would be a scholar who shocked the world.Unfortunately, such scholars are not Swiss, but Chinese.Of course, the professor didn't have any particularly bad thoughts about Hua Guo, but it was a pity that such a good student was not from his country, that's all.

Hearing the professor said that he wanted to graduate next year, An Yan thought the professor was angry.Hastily said, "

Not so, Professor. "

The professor gave up, shook his head and said, "Ann, I don't need your explanation. You are indeed the first student I haven't seen enough." When he said this, the professor stood up, looked out the window, and took a deep breath. Said in one breath. "Ann, I have taught many students, and you are the first one that surprised me."

"Those former students, although I have confidence in them, I know that it will be difficult for them to surpass me. But, Ann, you are different. Maybe I thought it would be very difficult for you to surpass me before, but now it seems that I must be mistaken gone."

"You may be able to surpass me, even much better than I imagined." The professor said as he tapped on the table, "So, Ann, I hope you can study hard, or that you need to be serious about academics." A serious attitude cannot be abandoned halfway. This is just my personal suggestion..." The professor suddenly babbled and said a lot, An Yan knew that these words were all for the purpose of making him better, so the professor said these words.Otherwise, the professor may not even say anything.

The professor treated him well enough, and An Yan was also very content.He nodded slightly and said, "Professor, I can understand what you mean."

"Just understand. It doesn't matter if you graduate next year or the year after, you just need to meet my requirements. It doesn't matter when you graduate." The professor shrugged slightly, expressing that he didn't care when An Yan graduated .It really doesn't matter to the professor when An Yan graduates, as long as An Yan can complete the tasks the professor told him, even if An Yan is graduating today, the professor will allow it.

"Ann, is there anything else you need?"

An Yan shook his head, he has nothing to do now.Then take advantage of this time to make up for the mechanics courses that were left behind before.An Yan was thinking about his study of mechanics, because mechanics is indeed a difficult point in physics, especially the content of dynamics, which has an unusual connection with engineering.That is, if he wants to study dynamics, he must study engineering.Fortunately, although engineering is an engineering subject, An Yan is good at science, especially if he is good at mathematics and physics, it will not be too slow to learn engineering.

"By the way, Ann, you don't have anything else to do recently, right?" The professor asked An Yan if he had any other arrangements recently, and An Yan didn't know what the so-called arrangement was.

"That is, do you have anything else to do recently? Do you have any plans recently?"

"Professor, I am preparing the materials for the thesis. It should be related to fluid mechanics."

"Is there a paper related to fluid mechanics?" The professor frowned slightly, although he didn't know anything about this aspect.But to say that he has not reached the top level.At most, it is an expert level, and it may not even reach the expert level.After An Yan said that it was a thesis on fluids, the first thing the professor thought of was the flow field problem.Among the flow field problems, the most widely involved are the laws of motion of the fluid and the conservation of incompressible momentum. The Navier-Stokes equation is also the legendary NS equation.

This equation has a history of hundreds of years so far, and no one has been able to solve it since it was established in 1845.This is the unsolved mystery of the two major departments of physics and mathematics.Scholars have reason to believe that solving the NS equation can make fluid mechanics progress rapidly in the actual development and application.

It even directly implements many design and experimental contents that have not been realized before.

However, why An Yan went to study fluid mechanics, this... is strange.He himself is not an expert in fluid mechanics, but he is considered a top expert in quantum mechanics.Although both are branches of mechanics, quantum mechanics and fluid mechanics are quite different.Even, it is impossible to compare them at all.

Fluid mechanics has been produced for hundreds of years, while quantum mechanics has only been proposed in recent decades.For example, the famous Schrödinger's cat is a representative experiment of quantum mechanics.

And Planck is the founder of quantum mechanics, which is also the strength of the University of Zurich.After all, Planck was originally a German, and the University of Zurich is in the German-speaking area.For the understanding of quantum mechanics, the University of Zurich is also very famous in the world.However, he didn't understand why his students didn't study quantum mechanics, but instead became interested in fluid mechanics.This makes him a person who has devoted his whole life to studying quantum mechanics, and he can't hang on his face.

"Ann, why did you choose flow fields instead of quantum field theory?"

Field theory, in physics, the distribution of a certain physical quantity in a region of space is called a field, such as temperature field, density field, gravitational field, electric field, magnetic field, etc.If the physical quantity forming the field changes only with the spatial position and does not change with time, such a field is called a steady field; if it not only changes with the spatial position, but also changes with time, such a field is called an indeterminate field.In practice, the general fields are unsteady fields, but for the convenience of research, the fields whose physical quantities change very little in a period of time can be approximately regarded as steady fields. ①

So the flow field and the quantum field theory mentioned by the professor are both field theories, but the directions of the two researches are different.

An Yan thought for a while and said, "Actually, I haven't fully understood quantum mechanics yet. I thought that after I thoroughly understood the existing theories of quantum mechanics, it would not be too late for me to do quantum field theory. As for the flow field, I didn't want to either. Research on particularly advanced things. I just want to give it a try in combination with the current environment and materials. If it really doesn’t work, then I’ll switch to studying quantum field theory.”

"Quantum field theory has become your second choice?" The professor was not angry, he just shook his head and said, "It seems that it is not the first day you want to study the flow field, right?"

"Professor, I'm just curious."

"What are you curious about? Curious about the NS equation?" The professor looked at An Yan with a smile, "If you want to study the NS equation, I think you are still a little tender."

"Professor." An Yan scratched his head and said, "I really don't want to study the NS equation." Let alone research, he doesn't even have the qualifications to touch the NS equation.He was just curious about the flow field, so he wanted to write a thesis on the flow field. As for the thesis on quantum mechanics, he planned to use it as his graduation thesis.

An Yan is not a fool, knowing that he can't touch something at the level of the NS equation, why would he bother to find something for himself that is uncomfortable and has no chance of winning.This is not his style. Seeing that An Yan really didn't seem to want to study the NS equation, the professor was relieved.It's not that he doesn't let An Yan study this thing, but that An Yan doesn't understand this thing at all now.

The NS equation is not a joke. Now that An Yan is researching, I am afraid that he will only be able to touch some fur, or even have no fur, and he will be confused by his whole thinking.With his current knowledge, he can only look for abusers.Naturally, he didn't want his students to be overwhelmed by a particularly difficult problem.

"You can write papers in Liuchang, but Ann, I have one more thing to trouble you here. You know that there will be exams in school before Christmas."

An Yan nodded, Christmas is a holiday, and the exams arranged by the school are naturally before Christmas.But is there anything else I need to do for the professor before Christmas?

"You also know that I took Roger to the previous academic conferences. This time I took you, so I didn't take Roger." When the professor said this, An Yan became more and more flustered.Could it be something about Roger that needs him to take over?If it's just that, An Yan can actually accept it. Since he has gone to the academic conference instead of Roger, it should be done to help Roger.

He certainly wouldn't put it off, but he just didn't know what it was like to do for Roger.

"Roger has already asked for leave to go home." The professor said, "So for the exam, I may have to trouble you to help Roger invigilate the exam."

Just a test?An Yan breathed a sigh of relief, it wasn't too embarrassing for him, it was easy to talk about, it was just an exam.He didn't need to be so nervous, he nodded slightly and An Yan said, "Professor, I just need to invigilate Brother Roger's exams? Is there nothing else?"

"No, it's also your job to correct the papers." The professor looked at An Yan and said, "Ann, these things were originally supposed to be done by Roger, but now Roger has something to do, so these things are shared with you If you think these things are too much, or if you think these things should not be something you do, you can also tell me."

"It's okay, professor, but I can still do these things." An Yan hurriedly stopped and signaled to the professor that he could do these things, and the professor nodded in satisfaction and said, "You can do it, since you can If you can do it, then I will leave this matter to you."

"Professor, don't worry, I will definitely handle this matter properly." An Yan took a deep breath, left the office and returned to the apartment.When he walked to the apartment, he found that Chen Tao was also walking back.

He waved at Chen Tao and said, "Brother Tao, why did you come back so early today?"

He remembered that Chen Tao usually didn't return to the apartment until after dark, but today it was much earlier.I don't know what happened to Chen Tao.

Chen Tao said with a smile, "Today's task was completed earlier, so I came back earlier, how about you?" He looked at An Yan, "Why did you come back so early? Didn't you mean to go to Professor Benson's office ?"

"Yes." An Yan nodded slightly, "After talking to the professor, I will come back naturally."

"Really?" Chen Tao rubbed his eyebrows and said, "How about it, did you tell the professor about your thesis?"

"Yes." An Yan nodded, "But the professor still seems to have some opinions. He still wants me to do a paper related to quantum mechanics."

"Is it about the Planck study?"

"Almost, and quantum field theory. I originally wanted to study the Hilbert space, but the professor said that it would be better to study the theory related to Planck."

"It should be the Planck Prize." Chen Tao touched his chin with his hand and said, "The Planck Prize is a very grand scientific award in German-speaking areas. Your professor said this for your own good, but what is the specifics?" It still depends on what you think. Quantitative sage Planck—”

"No Taoist Heisenberg? Maxwell? Mathematics devil Lagrange?" An Yan joked about the scientist who had been dubbed by a Chinese netizen, and the two walked into the apartment shoulder to shoulder. .

When he returned to the apartment, he walked into their apartment with Chen Tao.At this time, An Yan didn't have anything to do when he went back to An Yan. More importantly, An Yan felt that he could take a break today, and he didn't have to be too busy to do things.So he came to Chen Tao's apartment and chatted with Chen Tao and Liu Song.

Sitting on the sofa, Chen Tao went to pour water for An Yan, while Liu Song also sat on the sofa, resting his cheeks with his hands, as if he was thinking.

An Yan was very curious, and shook her hand in front of Liu Song several times, only to find that Liu Song didn't respond to him at all.Chen Tao came over with water and put it on the table.An Yan pointed to Liu Song and asked, "What's wrong with this guy? It seems a little... How should I put it, it seems that he is fascinated by something."

"Oh." Chen Tao glanced at Liu Song, and said to An Yan, "Don't pay attention to him, this guy has been thinking about twin prime numbers recently."

"Twin prime numbers?" An Yan was stunned for a moment, then immediately remembered, "Is it the twin prime number conjecture?"

"Yes!" Chen Tao nodded slightly, "Recently, the professor gave us a number theory class, and this guy insisted on challenging the twin prime numbers. Now you have seen it, and he has become like this. Tell us about this matter, don't think about it. Otherwise , is likely to become a fool."

"Twin prime numbers!" After thinking about it for a while, An Yan felt that this proposition was really interesting.Although there are very few physical applications in the actual sense, it is a good choice to think about it.

"No, An Yan, do you want it too?" Chen Tao gasped when he said this, "Don't tell me, you also want to make this thing."

"I don't have such an idea." An Yan shook his head, "The twin prime number conjecture is really not easy to solve, let Liu Song and you do this kind of thing."

"By the way, An Yan, let me ask you something."

"Tell me." Seeing Chen Tao's cautious appearance, An Yan thought that what Chen Tao asked was a big deal.

After sitting upright, he put his hands on his knees and said seriously, "Tell me, what is it?"

"Actually, you don't have to be so serious." Chen Tao folded his hands on his chest and said, "I just want to ask you if Professor Benson told you today to ask you to invigilate the exam?"

"Eh?" An Yan looked at Chen Tao and said in bewilderment, "Did you put a bug in the professor's office, and you actually knew about such things?"

"What bugs?" Chen Tao covered his face, "Professor Jesse also asked me to invigilate the exam, why do I feel that we invigilate the same class together?"

"No way, isn't it a class of one person? Even if it is a class of two people, you are in the Department of Mathematics, and I am in the Department of Physics. How can it be possible to invigilate the exam together?"

"It's true to say that, but I heard from my brothers and sisters that it seems that the Department of Physics and the Department of Mathematics are really invigilating the exam together. I'm thinking that if I invigilate the exam with you, I think it would be pretty good."

"Wait, what do you mean it's good to invigilate the exam with me? Why do I sound a bit awkward." An Yan hurriedly stopped and said, "I feel like we are going to do something, and you need to pull a It's like a padded back. But it's just an invigilator, so it shouldn't be like this?"

"I'm the first time invigilator, and I feel a bit stuck." Chen Tao lowered his head shyly, and An Yan got goosebumps when he saw it, "Can you be more normal for me?"

"Isn't that normal enough for me?"

"Do you think it's really normal for you to be like this?" An Yan touched his arm after he finished speaking, and he felt that his arm was a little cold.

"Okay..." Chen Tao said, covering his face, "I really want to know what you said, if we are invigilators, what will happen to those students making trouble?"

"It shouldn't be troublesome, unless they don't want to study at the University of Zurich. Since the professor asked us to invigilate the exam, I believe that group of students should still have some eyesight, and they can't come to mess with us for no reason. , and was expelled from school." An Yan thought for a while and said, "Let's talk about it then."

"Shouldn't you be going home for Christmas?"

"Well, are you going home?"

"I can't go back for the time being. I have to go to Oxford University with Professor Jesse to hold a mathematics conference. You know, there are many conferences that have sprung up after Christmas. I guess after attending the mathematics conference After that, I can go home and stay for more than ten days.”

"I asked the professor for leave, and I should be able to come to the University of Zurich until the end of March."

"I'll go, what did you... tell the professor?"

"Let's talk about my research paper at home, and then the professor agreed." An Yan shrugged and said, "Why doesn't your professor agree with you?"

"It's not that I don't agree, maybe I just think our self-awareness is not that good?" Chen Tao sighed, "I won't tell you this anymore, and if I go on, I think I might have to go to the professor to raise such an unreasonable question. request."

An Yan smiled, but did not speak.Looking at Chen Tao, he asked, "He's studying twin prime numbers. You really haven't studied them at all?"

Chen Tao thought for a while, took out the draft paper and put it in front of An Yan, and said, "I studied it a few days earlier than him, but unfortunately, it's useless, and it can't be calculated at all."

"Let me see." An Yan looked at the draft paper for a long time, and said in doubt, "Why don't you use the sieve method or the circle method when you use representation theory? I think the sieve method is the best for conjectures like twin prime numbers. After all, Goldbach's conjecture was also made using the sieve method."

"This is also the reason." Chen Tao seemed indifferent, pulled out another draft paper from another piece of paper and said, "No, this is the sieving method I used, and it still doesn't work."

"It doesn't make sense." An Yan held the draft paper and looked at it for a while, then shook his head slightly and said, "It's impossible to count it here and count it down."

"Yeah, it's already the limit at this point."

"Have you read the relevant documents and materials?" An Yan touched his chin, as if he was thinking about something.Chen Tao responded, "Of course, how can this kind of thing not read the literature, but it is useless. Those literatures have not been produced. Maybe someone has already started to solve this problem, but we don't know."

"There is also this possibility." An Yan thought for a while, "If that's the case, I won't bother you to continue solving the twin prime number conjecture. I'll go back and sort out the literature first, and I'm also going to write about the flow field. Paper. I hope this time the paper will not be read as a joke.”

"Don't worry, no one will read your jokes, you are considered a scholar now." Chen Tao talked to An Yan while looking at the draft paper.His demeanor was a bit weird, frowning, and he was very relaxed when he spoke.

An Yan smiled, and went straight back to her apartment, opened the mechanics book and read it.

Time passed quickly, he hadn't finished reading his mechanics, and the final exam had already begun.Sure enough, as Chen Tao imagined, he guarded the examination room with Chen Tao.Every student vacated a seat to sit down. When they came to the classroom with Chen Tao, the expressions of the students were still a little shocked.

Although they all knew that these two Chinese people were very powerful and well-known in school.But they are freshmen just like themselves, isn't this arrangement unreasonable?It can be seen that everyone has some opinions, but no one has an attack.After handing out the test papers, An Yan took the papers and looked through them, um, these questions are quite simple.It was not as difficult as the set of papers the professor gave him.

Chen Tao was writing a draft on the side, and An Yan glanced at Chen Tao next to him, and found that this guy was solving the twin prime number conjecture.I don't know which step he has achieved, but An Yan can't tell what this guy has achieved just by looking at him like this.Whoever he was, he wasn't interested in the twin primes conjecture anyway.I just learned a little bit about it when I was studying mathematics.

The students below saw the two invigilators above, and one of them was writing furiously.The other looked around, staring at them all the time.It made them feel like thorns on their backs, and they couldn't do any tricks.Some students muttered, why doesn't this guy write like that evildoer in the mathematics department!I heard that this guy is working on a thesis again now, aren't you panicked at all?

Hurry up and write your thesis. Anyway, let us copy a few questions.

It's not that An Yan can't ignore the thoughts of the students below, he also came here like this before.It's just such a simple question, as students in prestigious schools have to plagiarize, isn't it a little too weak?

He just looked at the students below, and there were some who wanted to plagiarize, but he gave up the idea of ​​plagiarism.First, they didn't want to have any conflicts with An Yan and Chen Tao.Although the two are from China, their professors are the top experts in the school, since they were asked to invigilate the exam.It can almost show that they are the disciples of the school's top bullies. People like this, when they have disputes with ordinary students, especially when ordinary students don't take it seriously, almost ordinary students can only be expelled. There is a way to go.

How could it be possible for him to be expelled so easily after finally studying at the University of Zurich.The letter of introduction from the University of Zurich is not so easy to get. They are not like the students from Huaguo who are either specially recruited, or the professor writes the letter of introduction and asks them to go directly to the school to study, or the kind of full scholarship.

It is impossible to ask them to do it.

"Just do your own thing, don't look around, it's not necessary, it's really not necessary!" After An Yan spoke, the classroom fell silent.Even the students looking around are not looking around, but staring at their papers in a daze.

"Tsk!" With a soft tut, An Yan read the paper again. He always felt that the paper was quite simple and there was no problem. Why did everyone look so painful?Can't it?If you listen carefully to the teacher's class on the subject and spend a little time reviewing it after you come down, you will never find this set of papers difficult anyway.

Chen Tao put down the pen in his hand, raised his head and glanced at the classmates in the professor.Finding that everyone was doing their own papers, he leaned into An Yan's ear and said, "Why don't we spend Christmas together?"

"Forget it." An Yan grabbed a handful of hair, "I'm not used to celebrating Christmas."

"Hey, there is no such atmosphere in China. I think the atmosphere abroad is quite good. After all, they have been celebrating Christmas. I thought about it. Anyway, we will not go home anyway, so we just get together and have a meal. hot pot."

"Do you have any background information?" An Yan lowered his voice and discussed with Chen Tao.

"No, but I know how to make hot pot bottom ingredients." Chen Tao said flauntingly, "I was afraid that I would not be able to eat them after going abroad, so I spent more than a month learning how to make hot pot bottom ingredients."

"Is it reliable?"

"It's very reliable. If you don't believe me, you can go back and ask Liu Song later... Forget it, don't ask him. I think he has been absent-minded recently. He has been thinking about twin prime numbers. Believe me, it must be delicious."

"Then I'll go shopping, and you'll be in charge of making the hot pot base." The two were talking happily when An Yan's cell phone rang.

"I'm going out to answer the phone." An Yan thought it was the professor or other seniors who called him and asked him to help.Walking out of the professor, he took out his mobile phone and saw that it was Gu Weize's name.An Yan was stunned for a moment. He remembered that the last time he talked to Gu Weize was in October or November. Anyway, he only talked to Gu Weize a long time ago.

"Hey, what's up with Gu Weize?" After pressing the answer button, An Yan went straight to the topic and asked Gu Weize if there was anything wrong with calling him.

"Xiao Yan, can I call you if I have nothing to do?" Gu Weize's voice was full of grievances, and An Yan couldn't hear such a voice, "Gu Weize, please talk to me, I didn't say you can't call Phone. I'm... working on something right now." An Yan didn't tell Gu Weize about his invigilation, and if Gu Wei knew about it, he might do something out of the ordinary.

"Xiao Yan..." Gu Wei smirked on the other end of the phone, "I thought Xiao Yan wouldn't answer my call."

"Gu Weize... have you been drinking?" An Yan was taken aback for a moment, did this guy go to drink?

"A little bit, just drink a little bit!"

"You can't drink at all, and you are so drunk, will I believe you when you tell me you only drank a little?" Before An Yan finished speaking, the phone seemed to be snatched.He heard a loud voice over there, and then another man's voice rang in An Yan's ear, "An Yan?"

"It's me, are you?"

"Chen Hanlin, do you still remember? The former high school sports committee member!"

"It's you." An Yan felt relieved, Chen Hanlin and Gu Wei are good friends.Since he was by Gu Weize's side, there shouldn't be any problem with Gu Weize.

"I heard that you are at the University of Zurich now?" Chen Hanlin was talking, and there was some noise over there.It seemed that Gu Wei was chattering about something.

"Well, I go to school here in Zurich. What's wrong with Gu Weize? Broken in love? He went to drink suddenly?" An Yan was very confused. He remembered that Gu Weize was not a drinker, so why did he suddenly go to drink?He and Gu Wei have been together for more than ten years, even if they hang out with friends, the number of times they drink is very few.I didn't hear that Gu Weize liked to drink in college before, and Gu Weize told him that he didn't drink.

"It's not lovelorn." Chen Hanlin was one head and two older, while Gu Wei on this side pretended to be crazy by drinking, and An Yan on the other side didn't seem to have a very good tone of voice.

He was about to say something, but unexpectedly there was a burst of birdsong from An Yan's side.

That's right, in Chen Hanlin's opinion, it was Niaoyu.

"Ann, why are you outside the door?"

"Professor, are you here to invigilate the exam in person?" An Yan didn't hang up the phone, but put down the phone to talk to the professor.

"Just passing by, Ann, do you have any plans for Christmas? If not, you can also go to my house."

"Professor, I have already agreed with Chen Tao that we should spend Christmas together."

"It's okay, were you on the phone just now?" The professor said with a smile, "I think your expression is not very good, it should be a very important thing? Do you need me to watch it?"

"Professor, no need, I can solve this matter right away."

"Don't let some things affect your mood." After the professor finished speaking, he walked away.

An Yan then picked up the phone and said to Chen Hanlin, "The professor came over just now, by the way, do you know why he wants to drink?"

"Why else?" Chen Hanlin rubbed his eyebrows, "Because you ignored him for more than a month, and he said he wouldn't look for you, so you wouldn't look for him. Have you forgotten him?"

"Is he drinking to find his presence?" An Yan's voice was a little cold, "Is he not drunk?"

"It should not be in place yet." Chen Hanlin glanced at Gu Weize next to him, and shook his head helplessly at him.Let him stop pretending to be crazy with alcohol, this trick is useless to An Yan.

"How many people went to eat?"

"That's it, Gu Weize and I..." Chen Hanlin felt chills down his spine when asked by An Yan.

"Who has the clue to drink?"

"he……"

"Didn't I tell him? I'm very busy recently. Give him the phone and I'll say a few words to him."

Chen Hanlin handed the phone to Gu Wei and said, "Stop pretending, An Yan wants to talk to you. You can talk about it yourself, I really can't help you with this matter."

"Xiao Yan!" Gu Weize's voice was particularly aggrieved, "You have ignored me for more than a month."

"I told you that I've been very busy recently. Can you stop thinking about things in the laboratory? Will you still drink in the future?"

"Stop drinking, is Xiao Yan doing anything else recently?"

"Yes, correct the papers, and go to the Ugly Country to hold an academic conference. After returning to China, there are still things the professor asked me to do, and I have to write a thesis." After An Yan finished speaking, he added another sentence, "Can you stop thinking so much? complex?"

"I..." Gu Wei wanted to say something, but the words got stuck in his throat and he couldn't speak.
