Summer 2026.

Old campus of Jinling University.

old stone walls are covered with mottled shadows. The cicada sounds of the Wutong tree tops are like ancient times. In this prosperous city, they are alone in the tranquility of the smell of books.

But today's Day is a little unusual for the old campus.

Scholars in formal clothes walked through the blue stone road in front of the gate. Foreigners with high noses came and went in front of the old buildings built in the period of the Republic of China.

Overnight, it seems that it is back to decades ago. The ancient old school seems to have gone through time and space and restored the glory of the National University in its heyday.

No, to be precise, it should be more dazzling than the glory of that heyday.

Because at that time, although some foreigners came here to give lectures, most of them walked with their heads held high, arms swung and toes held high. Today, people's faces are mostly modest, regardless of color, age and gender.

No one is more noble.

Everyone is equal in the face of knowledge.

No one will feel inferior for their skin color or culture.

Asia first?

Now, that's just a modest statement.

As if it was to celebrate the old school and rejuvenate its youth, even the withered and yellow vines on the walls of the school seemed to sprout new shoots.

"Professor Qin."

heard someone calling himself, standing under the Wutong tree, looking at the Qin Yue of the old school, and came to his senses in a trance.

He nudged the gold rimmed glasses on the bridge of his nose and looked at the assistant next to him.

"Is it going to start?"

The assistant nodded excitedly, his voice full of excitement.

"One hour left! The conference organizing committee just called. I hope you can go to the backstage to prepare it. "

Four years ago, at the St. Petersburg International Congress of mathematicians, Xi, the leader of the International Federation of mathematicians, announced that the 2026 International Congress of mathematicians would be held in Jinling.

This news excited the mood of all Chinese mathematicians and excited the mathematics departments of all colleges and universities in Jinling.

There was little suspense. Jinling university took over the organizing power of the International Conference of mathematicians and set the venue at the old campus of Jinling University.

In order to host this remarkable event, they have prepared for it for four years!

Now it's finally time to test their results.

"I see Call them back. I'll be right there. "

As he said this, Qin Yue took back his sight from the old school of the Republic of China and looked at the foreign scholars standing under the old stone wall to take photos. He couldn't help but smile.

"When was the last time so many people gathered in this old campus?"

Hearing this, the assistant standing next to me was dumbfounded and said with a smile.

"It seems that for some time If you remember correctly, it was about two or three years ago when academician Lu held a report meeting here. "

Two or three years ago

Qin Yue's eyes suddenly darkened, and his tone also brought a touch of sadness and nostalgia.

"It's been two years..."

How time flies

Everything here has his shadow, but he is not here

Backstage lounge.

The staff helped Qin Yue with his appearance and tie.

About two years ago, shortly after the news of the shipwreck spread, he quit his job in Princeton, boarded the flight back home, and came to Jinling University, where his most respected tutor once worked.

In fact, prior to his resignation, Professor feverman had intended to train him as his successor to take over as head of mathematics at Princeton University.

However, the post of head of Princeton mathematics department did not leave him. In the face of Professor feverman's retention, his decision still remained unchanged.

In his memory, Lu Zhou told him more than once that he wanted to build Jinling University into the world's top mathematical center.

Now the boat is gone, and his dream still needs time to realize.

In that case, it's up to you to finish the road for him!

Qin still remembers that when he just returned to China, Jinling University was in a sad atmosphere, especially in the mathematics department.

In a sense, his return has also revived the morale of the University's mathematics department.

As one of the most favorite students of academician Lu, an internationally renowned mathematician, he soon took over the banner of Jinling school, replaced the retired president Qin, and took the post of president of JINDA School of mathematics.

In the past two years, with his efforts, the Mathematics Department of Jinling university has become a world-class mathematics department, leaving the domestic peers far behind.Now the International Conference of mathematicians has been held as scheduled. As the new flagman of Jinling school, or Luzhou school, he will stand on this international stage and give out the voice of Chinese scholars on behalf of the Chinese mathematical community!

The opening ceremony of the International Congress of mathematicians has finally begun.

In the same way as the previous sessions, Qin Yue, representing the Chinese mathematical community, came to the stage and read the opening speech after the speech of the Secretary General of the International Federation of mathematicians.

Then came the Gauss prize, the fields prize and a series of the highest honors and awards in mathematics.

When several winners came to the stage and took over the medal from the Secretary General of the International Federation of mathematicians, there was an impassioned national music in the venue.

In the song of the zither, the flute and the drum, a grand performance of literature and art officially opened the curtain for this remarkable event

“…… This is the best meeting of mathematicians I have ever attended, which gives me the best sense! " When he came out of the conference hall, Professor Witten's face was full of excitement, and he said to the professor next to him, "although I don't know what kind of feeling it is, compared with the ballet in St. Petersburg and Rio de Janeiro The original jungle show is going to be a lot more impressive. "

In fact, objectively speaking, the ballet performance at the St. Petersburg convention was good, but it may be short of funds. As for the performance of the latter, although it seems very lively, I always feel that it's a little too busy. In addition, because of the serious public security problems in Rio de Janeiro, if not for the wonderful report meeting of the land boat, that mathematician conference could hardly be described in a word.

"Compared with the performance at the opening ceremony, I am more interested in whether I can see anything interesting at this conference..." His eyes were moving in the poster area outside the great hall. The expressionless Professor deline suddenly had an unexpected expression in his eyes.

Keenly caught the change of expression on his old friend's face, Witten raised his eyebrows with interest. "It seems that you have found something."

"Yes."

He nodded his head and left the sentence without any explanation. He went straight to the poster area.

Out of curiosity, Witten followed his old friend, followed him through the dense crowd, and stopped in front of a white board.

Looking at the line of calculation on the whiteboard, Professor deline's brow slightly wrinkled.

“…… Cauchy Riemann equation? "

Hearing this, the young man standing in front of the whiteboard had an unexpected expression on his face.

"Yes It's hard to believe. Are you also studying this direction? "

Obviously, the boy didn't recognize who he was.

Professor deline smiled a little and said, "I'm not studying this direction, I just think you are familiar with the mathematical methods If you are not mistaken, your formula 3 should be a generalization form of l-manifold, and your research topic is just a corollary of Hodge's conjecture. "

The young man's face showed a shocking expression, just like looking at the monster, looking at the old man in front of him.

“…… Who are you? "

"It doesn't matter who I am, I'm just curious," Professor deline continued, looking at the poster hanging next to the whiteboard. "Since you're studying Hodge's conjecture, why don't you write it down on the poster?"

Hearing this sentence, the young man's face showed a bit of shame, embarrassed to scratch the back of his head.

"I want to, but I always feel It's not very good to write it directly. '

If he's a little older, he'll be just as young as he is now. Even if he's serious about studying this century's problems, he'll be regarded as a joke by others.

At a glance, he saw through his inner thoughts, Professor deline said quietly with a light smile.

"Those things you worry about are of no importance at all. Academic studies never regard age as the top priority. If you want to talk about youth, you are far worse than my former student. At your age, he's already a famous young man in mathematics

"Is it so powerful..." The young man's face was full of shocked expressions and his mouth was opened in surprise.

"What's your name?"

“…… Zimmer. "

Professor deline nodded.

"Jimo It's an interesting name. You should be a little more confident in your research results, and be able to study to this extent. You have defeated more than 90% of people in Princeton and your age. "

Looking at the inexplicable youth, Professor deline continued to ask.

"By the way, who is your professor? I want to talk to him for a second. "

Hearing this, Jimo's face immediately showed a sense of pride.

However, the proud expression did not stay on his face for long, and was soon replaced by a touch of sadness and loneliness.“…… You may not be able to communicate with him. "

Professor deline frowned.

"Is there anything inconvenient?"

"No, it's not inconvenient for Fang," Jimo shook his head and smiled apologetically. "My tutor It's a land boat. "

Land boat

At the moment of hearing the name, Professor deline 's pupil contracted slightly.

It's like opening a closed door, and the memory gushing out from the bottom of his heart makes his eyes appear a little disappointed.

For the past two years, he deliberately did not remember the name, but the box of memory was opened.

"You are a student of land boat." Looking at the young man, Witten saw an accident in his eyes, smiled and joked, "I have a hunch that I may not be able to see you on the stage of the fields prize for a long time."

Jimo, embarrassed to smile, scratched his back.

"I will try my best My tutor told me before that he asked me to take a long-term view, not to pay too much attention to the achievements of the IMO competition, and take the fields award as the goal. "

"Hahahaha, right? That's really something to look forward to. "

Looking at the overjoyed Witten, deline said rudely.

"Are you sure you can live to that time?"

Witten coughed: "you can have more confidence in me. In ten years, I still have the rest. What's more, a magnificent era is just beginning. If it falls down the moment before the opening, isn't it What a pity? "

Just when the two old men almost didn't quarrel about their age, there was an incredible exclamation in the report hall No. 1 not far away.

On the stage, Han Mengqi wrote down the last line of formula on the whiteboard and gently put down the marker in his hand.

Transcendence of Riemannian zeta function at odd positive integer point.

This is the subject left by Lu Zhou when she was determined to turn to pure mathematics.

She still remembers what master said at that time. He didn't ask her to prove the whole proposition. He only asked her to make a small breakthrough in this direction. Even if she could find a transcendental number that hasn't been found, it would be her graduation.

Now, she has obviously exceeded the expectation of Lu Zhou at that time.

She not only found the transcendental numbers on the zeta function that had not been found in the mathematical world, but also proved the whole proposition that is,

for any n ≥ 1, ζ (2n + 1) is also the transcendental number!

Although it takes a long time

But she did it in the end with her own strength!

"Incredible She is surprisingly adept at using mathematical tools. In particular, the unified theory of algebraic geometry is the finishing touch It's not like a new mathematician can do it at all. "

Looking at the lines on the stage, Schulz's face was full of unexpected expressions.

It was the famous quasi Riemann conjecture in the field of mathematics that was proved by the little girl on the stage at the moment. Although he has not studied the subject, it is not difficult to feel it just by looking at the time when the subject exists, and the difficulty is not small.

Sitting next to Schulz, Professor Fieldings squinted at him.

"Are you kidding? Who just began to study mathematics, will take this level of problem as a research topic. "

With that, the old man turned his eyes to the stage and squinted slightly.

“…… But this face looks strange. "

"It's like a student on a land boat," Schulz said, squinting for a long time. "I remember I seem to have met this man in his office. "

"It was his student..."

It seemed that there was nothing strange about it for a moment, said Professor fortings, leaning back in his chair, after a moment's meditation, in a positive tone.

"It's too late for this session But the next fields prize must have her name. "

Surprised to see Professor faltins, but Schulz did not say anything.

In principle, it should be the same.

Number theory itself is the most complex field in pure mathematics. If we can make a major breakthrough in this field, a fils prize level honor can be matched.

Plus she is a student of land boat, no one should object.

"Don't just talk about other people," said Professor fortings after a look at Schulz. "I've been looking for an opportunity to ask you how is your research?"

"You mean that?" After a moment's hesitation, Schultz's face soon showed a smile of sunshine, "of course, that subject is about to end. Or to put it another way, it's just as bad to publish it in a paper. "

Fartins: are there any journals willing to accept your research"I haven't found After all, it's not a good topic to classify, "Shultz continued with an embarrassed but polite smile after a subtle shift of his eyes." if it's really not possible, we're going to find a journal to publish the results Anyway, I'm not particularly concerned about influencing factors. "

At Schulz's words, Professor fortings didn't say much, just looked up at the platform and said a meaningful sentence slowly.

"A scholar's golden age is only ten years. It took two years, but only for such a result Is it worth it? "

Schulz was silent for a moment about this sentence.

After a long time, looking at the little girl on the stage bowing to thank him, and the report hall that began to leave, he shrugged gently.

"For me, it means an end, an end to the expedition two years ago."

"I don't think it's about gain or loss..."

"So it should be worth it."

……

Perhaps with the light of land and boats, this year's International Congress of mathematicians is particularly lively.

Quasi Riemann conjecture is proved by the students of Lu Zhou!

Just after the first report meeting on the first day, the atmosphere of the whole conference was pushed to Gao Chao.

However, for Han Mengqi herself, there are not many waves in her heart.

She is very clear that her work is only a small achievement based on her master's work, which is far from a breakthrough.

Get rid of those who try to catch up with themselves. Han Mengqi, who comes to the backstage lounge, is about to change her formal clothes. However, at this time, the door of the lounge suddenly opens, and an acquaintance pushes the door open and walks in.

“…… Dr Yan

Stop to understand the button hand, Han Mengqi looked at her incomprehensibly, not quite understand why she would appear here.

Not much nonsense, went to Han Mengqi's front, Yan Yan said solemnly.

"May I ask you something?"

“…… What's up? " Although I don't think I can help her, Han Mengqi politely replied.

Yan Yan: "your sister is missing. I want to know where she has gone! Do you have any clues? "

After she went to Beijing that day, Chen Yushan disappeared from everyone's sight, just like the world evaporated.

The only clue is that before she disappeared, she once went to 301 Hospital and visited several doctors funded by star technology.

Then, no one knows where she went.

In fact, it didn't attract anyone's attention at the beginning, including her resignation from star technology. Most people just expressed regret that she was too sad and needed to rest for a while.

Until later, she never appeared again. Many people around her realized the seriousness of the problem.

Because it is not like a criminal case, or a foreign force, the matter was finally transferred to the general information section for general investigation.

Yan Yan, who has just been transferred to the intelligence department, has limited resources to use. She can only use the stupidest method of visiting and investigating, starting from the people around her.

Hearing Yan Yan's question, Han Mengqi shook her head in a daze.

"I don't know."

See Han Mengqi what also don't know, Yan Yan immediately urgent, said.

"You're her sister, and there's no clue at all? Did she say where she particularly wanted to go? "

"Where do you want to go..." Han Mengqi opened his mouth, and suddenly a memory appeared in his mind, with a touch of surprise in his eyes.

Keenly noticed the change of her expression on the face, Yan immediately asked.

"What do you think of?"

"Where I want to go in particular Yes, it is, but it's impossible. "

As she spoke, Han Mengqi's face showed a strange expression.

So far away, can we really go there?

After all, with the current technology on earth, let alone a certain stellar system outside the solar system, even the Kuiper belt may not be able to fly out
