Jinling University.

In the modern office, an old man with gray hair is standing in front of a lifelike hanging picture, staring straight at the man on the picture. It seems that he has fallen into a very distant memory.

At this time, footsteps came from outside the office, followed by two soft knocks on the door.

He did not take his eyes away from the picture, turned his back to the old people in the office, and said in a steady and dignified voice.

"Come in, please."

The door opened.

A tall, thin, bespectacled young professor opened the door and came in.

"Tutor, would you like to see me?"

The man standing at the door is sun Jingwen, about thirty-four five years old.

As a rookie in the Mathematics Department of Jinling University and even in the Pan Asian mathematics field, he was honored with the fields award at the age of 31, and regarded as the most promising young scholar to win the land boat mathematics award before the age of 40.

At this moment, standing in front of him, staring at the old man with the hanging picture, it's even more amazing.

His name is Qinchuan. Although he is 80 years old now, he still plays an important role in the field of mathematics. When he was young, he won the fields prize at the age of 30, and the highest honor in the academic world at the age of 40 - the land boat mathematics prize. As one of the top scholars in the field of mathematics, his research in the field of number theory is at the peak, especially for the understanding of group construction.

Although he has devoted himself to education since he won the Wolf Prize for mathematics, a lifetime achievement award, and has rarely appeared in the top journals of mathematics, many people still regard him as the leader of the land boat school.

In addition, he has a layer of unimportant identity.

That's the second generation "leader" of Lu Zhou school, the grandson of Qin Yue, Lu Zhou's eldest disciple

In the face of the students' questions, the old man didn't answer his questions directly. His turbid pupils were still staring at the hanging picture. After a long time, he said slowly.

"Do you know who is on this poster?"

Looking at the man on the portrait, sun Jingwen was slightly stunned, and there was a trace of confusion in his eyes.

This confusion is not about the person in the portrait, but about the problem itself.

"It's my grandfather Any questions? "

No matter overseas, at least in the land of Pan Asian cooperation, this face is not only a popular lover, but also a household name. As a scholar who has pushed the scientific process of the whole world forward for more than one hundred years with his own efforts, as long as he has studied the field, there are stories about him.

Maybe not everyone is in awe, but at least most people will not be unfamiliar with the name and face.

Let alone Jinling University.

Every whiteboard and tile here has witnessed the legend he left behind.

Even now, 100 years later, the graduates are proud to be alumni with Academician Lu.

"That's right," the old man nodded and looked at the hanging picture on the wall. His turbid pupils began to float a little. "It was the most glorious era of our school and the most prosperous era of the academic community."

There is no master after the 21st century.

Not only in mathematics, but also in academia.

The prosperity of an era is by no means the achievement of one's great power, but the man hanging on the wall has undoubtedly stood at the peak of that era.

Although he didn't want to say that "the building of science has been completed, and all that is left for future generations is some work to add bricks and tiles", he was already at the top of the academic circle, but he didn't see any hope of breakthrough.

Even in the eyes of others, he has made a lot of outstanding contributions in the past 80 years and retired with full glory. However, only he himself knew that all the research he had done from the beginning to the end was just the excavation and repair of the academic heritage left by the ancestors of the Lu Zhou school.

After living for 80 years, he didn't leave a pioneering achievement, and only his own bitterness was clear.

Many years ago, he talked with the dean of the Institute of physical education of Jinling University and got the same answer - the man seems to have drained the aura of the next 100 years, and the whole academic community seems to have fallen into a kind of prosperity trap.

A variety of research results were born in a blowout mode, and the growth rate of the number of papers and influencing factors reached a new high every year. Among them, there are some excellent research results, but none of them can reach the level of "algebraic geometry unified theory".

The same is true of physics. Since the theory of hyperspace, there has not been a breakthrough theory in the field of physics for nearly a hundred years.

Although I don't know what other disciplines are like, Qin Chuan believes that this is no accident.“…… My grandfather is his student. "

"Whenever he spoke of that name, his face would be filled with nostalgia and regret. I have heard from him more than once that if he could live another two years, even one year, we would not be in such a bad situation. "

Sun Jingwen frowned, a little confused in his eyes.

He doesn't know what the hell is about here?

Although the brilliance of the school was not as great as it was in those days, it was never disgraced.

Jinling university is still the center of the world's mathematics circle, and the land under their feet is a paradise for mathematicians all over the world.

However, even though he was full of doubts, he did not interrupt the professor, but quietly waited for the old man to continue.

After pondering for a long time, the old man said slowly.

"These days, are you closed in the library?"

"Yes," Sun Jingwen nodded. "My research on Dirichlet function is just entering a critical stage. If you didn't call me, I would still be in the library at the moment."

"Then you seem to know nothing about what happened yesterday."

"Yesterday?" Sun Jingwen frowned. "What happened yesterday?"

"Alone It's a man, to be precise, who claims to be from 2024. "

“2024?” Sun Jingwen is slightly shocked for a moment, "do you sleep? It's a long sleep. "

The old man sighed softly, stared at the hanging picture on the wall, and said slowly.

"The point is not how long he sleeps, but that he happens to be from Mars."

"From Mars Wait, you mean Are you?! "

His eyes widened for a moment. Sun Jingwen couldn't believe looking at his tutor. His pupils were filled with shock.

He thought of a rumor.

Or a legend.

Although that legend is only a short line in the history of mathematics, that short line of words has changed the history of Mathematics - and even the world's future 100 years since the beginning of the 21st century!

The shock in the pupil converged a little, sun Jingwen tried to calm himself down, but it didn't play a role.

At this moment, he could not tell whether he was surprised, excited, shocked and worried after hearing the news.

“…… How is it possible that he is still alive? This It's too much to say. "

"I think it's too exaggerated, but he does claim it, and it's reported in the news as well."

The old man was silent for a while, took back his sight from the hanging picture, looked at the student standing by, and continued.

"You and I are the lineage of the Lu Zhou school. Up to now, this matter has nothing to do with us."

"The meaning of that name is not just a name, it is a symbol."

"Whether he's real or fake."

"I have to see him!"

……

In the Mathematics Department of Jinling University and even in the international academic circle, when the storm surged because of the shock news that "the man is still alive", Lu Zhou, who is in the center of the storm eye, now has an expression of ignorance on his face.

When the two groups of silica gel finally moved away from his face, and saw a few lines of digital stripes in the dark pupil, he suddenly guessed something.

With uncertain tone, the boat asked tentatively.

"You are Xiaoai? "

"Mm-hmm! How clever the master is! hey. (/ / / ω / /))

in the pupil with black paint, the abstract digital stripe changes the pattern in an instant under the fluctuation of emotion.

It was after seeing these two words that Lu zhoucai 100% determined that the guy in front of him was Xiaoai.

After all, it's been 100 years.

Still use this kind of old Yan character, also can only be with oneself from the same era of antiques.

"Master, in the past 100 years when you were away, little AI really missed you QAQ "

" I miss you so much, "he said, reaching out and touching his light hair. The expression of Lu Zhou was spoiled and smiled," I've kept you waiting for a long time. "

"Well, you need to eat first, take a bath first, or play with Xiaoai first. (/ / / Omega / /)

"eat first, and I'm a little hungry."

"OK! (???)? "

Yan's words in her pupils are still full of energy. I heard that her master is hungry, and Xiaoai quickly gets up from the ground, just like in her own home, and runs into the kitchen.

However, after rummaging through the kitchen for a while, he quickly and dejectedly poked his head out."Master There seems to be no ingredients in the refrigerator. Can I have take out today? QAQ "

Lu zhousighed.

"I'll order it myself."

I'll order the take out boat.

After all, eating is the top priority. After getting the personal terminal, Li Gaoliang taught him the first thing is how to use the city cloud system to call take out service.

It's about 20 minutes. The takeout will be delivered soon.

Instead of the delivery guy in the yellow coat and the blue coat, a meal delivery drone with two pairs of rotors hanging on its head put the meal directly at the special UAV docking point on the windowsill.

In today's era, almost every family's windowsill will reserve such a piece of semi open space. It's not only used for taking out and selling, some express delivery and other things, but also sent to people's homes in this way.

Lu Zhou broke off his chopsticks and tasted the barbecue and bibimbap 100 years later with excitement.

Although the taste is not the same as before, it is still delicious as before.

In particular, the smooth q-shaped rice, the tender roast meat in the Souffle and the cumin powder evenly spread are full of happiness.

"Say, what have you been doing all this time?"

With his hands dragging his chin, he sat on the opposite side of the boat.

"AI is very good! Apart from doing some tour guide work at the former site of Jinling Institute of higher learning, I didn't do anything else! Chicken ribs are more likely to make complaints about the

.

If you want to see what kind of characters it uses, you must stare at its eyes.

However, staring at the girl's eyes, Lu Zhou felt a little uncomfortable.

What do you say?

Maybe he is too polite.

But if you ignore those Yan characters, you will feel less.

Lu Zhou: "the old site? So Has the Jinling Institute of higher learning moved? "

AI: "well, it was moved decades ago. The old site has been transformed into a tourist attraction. In order to prevent the staff of the scenic spot from discovering that Xiaoai is using electricity secretly, Xiaoai is very hard! When QAQ "

thought that he had disappeared for a whole century, and only had time to leave an endless" hide well "with him, the heart of Lu Zhou could not help but feel ashamed and embarrassed.

"Hard work for you."

After hearing this hard, AI, with her chin in her hands, shook her head gently with a shy and satisfied smile on her face.

"Hey, you're welcome. I'll be glad if the master comes back. (/ / / ω / / /)

there was a knock at the gate.

Hearing the knock on the door, AI stood up from the chair with her hands on the table.

"Xiaoai, open the door! (???)? "

" wait a minute, let me do it. "

Thinking that the people might be from the frozen human rights protection foundation, Lu Zhou raised his hand to stop Xiaoai.

After putting the chopsticks on the bowl, he pushed away the chair and stood up, walking towards the porch himself.

However, when the land boat opened the door and saw the man standing at the door clearly, the whole person seemed to be stupid, and suddenly froze there.

The lips opened and closed involuntarily, and the boat subconsciously squeezed a name out of the crevices.

“…… Xiao Tong. "

However

What the man said next was to wake up the boat for a moment.

"For the first time, I'm Lu Xiaoqiao, President of the frozen people's rights and interests protection foundation."

Bowing politely to the landing boat, the woman in her early twenties, standing at the door, looked at him uneasily, and continued.

"Excuse me Are you my great grandmother's brother? "
