An apartment near the University of Bonn.

Looking at Professor Schultz, who is packing, Professor Stix, who is going to invite him out for a drink, said in surprise.

"You are Where are you going for the meeting? "

If he is not mistaken, there should be no academic conference worth attending recently.

"No," Schultz answered the question briefly. He chose a jacket from the closet, slipped it into the trunk, and then casually replied, "this is not a meeting, it's an invitation from Professor Lu. I'm going to visit China to discuss some academic matters with him. "

"China? Professor Lu "But at the last meeting of mathematicians, Professor Lu didn't say that he didn't think about studying mathematics for the time being."

"He did say that, but it didn't matter," Schulz said with a smile. "His exit was a loss to the math world, and now he's back in his best field, number theory. Anyway, I think it's a good start."

"What can I ask?" asked Stix curiously

"ABC guess."

"ABC guess..."

There was an inconceivable expression on his face, said Steves in a low voice, "but I think it's also true that there is no challenge for him to solve mathematical problems, and only this kind of problem that doesn't seem to be able to be solved by modern mathematics can arouse his interest."

Closing the suitcase, Schulz looked at him and asked.

"Do you want to go together? You are an expert in number theory. "

Stix shook his head and said, "I'll let it go. I don't know him very well, and he didn't invite me I wish you a good time there and hope to hear the good news from the other side of the earth. "

Shultz said with a smile.

"That's for sure."

……

Just as Schulz had left for China, he was sleeping with his chin buried in the collar of his windbreaker at Kyoto International Airport on the other side of the earth, sitting in the waiting hall of the new moon.

At this time, the mobile phone alarm rings suddenly, waking him up from his sleep.

"Is it time?"

Kneading his nose, the moon was about to stand up from the chair when he was a little confused. Suddenly, his eyes fell on the TV screen on the ceiling of the waiting hall.

On TV, the NHK news is on.

Sitting in the studio, the hostess broadcast the latest news in a clear voice.

“…… Recently, China's manned fire landing Office held a press conference at which it announced major findings of research projects related to the manned fire landing plan. At the conference, a spokesman for the Chinese side announced that their scientific research team had found a clastic vein suspected of being formed by biological sedimentation in a 120 meter deep underground rock formation on Mars in an accident. "

In the TV screen, the camera picture is switched from the studio to the scene of the press conference.

A spokesperson in formal dress stood in front of the camera, facing the dense microphone and camera of the whole audience, and repeated the story of the news anchor in the studio.

In addition, the spokesman also disclosed.

According to the analysis of carbon isotope, these bioclastic rocks were formed about 2 to 2.5 billion years ago.

If this research is true, this discovery will not only be a strong evidence of the existence of life activities on Mars, but also more likely to reveal to humans how the ecosystem looked when the atmosphere of Mars was not blown away by the solar wind in the Proterozoic period two billion years ago.

Until now, there have been two different views on whether Mars has a complete ecosystem

"Cosmonaut?"

Staring at the news on the TV, he muttered to himself.

That sounds interesting.

But

It doesn't seem to have much to do with myself.

Just as he was thinking about it, there was a sound of excited discussion.

"There are creatures on Mars?"

"So powerful..."

"I don't know when our astronauts will be able to go up."

"It's too hard NASA has failed, let alone us. Alas, if there were not Professor Lu, they might not be able to send people up. "

"Do you think they actually saw Martians there? It's just not public. "

"How could it be Anyway, these are all specimens from billions of years ago. "

It doesn't seem like it's just fun.

At last, I took a look at the time in the lower right corner of the TV. Wang Yuexin indifferently picked up the suitcase beside the seat and walked towards the gate quickly……

Jinling University.

An office at the end of the corridor of the experimental building.

"Your working environment is much cleaner than mine," Schulz said in an envious voice after standing in the office of the land boat and looking around. "I can hardly find a place to move my feet. My assistant complains to me the most every time, that is, he doesn't know which paper I need and which one I don't need As a result, everything is piled up there and no one cleans it at all. "

Hearing this, I don't know if it's a compliment, so Lu Zhou smiled sheepishly.

To be honest, the reason why his office is clean is not because of his good habits. It's just because he hasn't been here much this year, that is to say, he has made more appearances in school recently.

Standing nearby, Perelman, who had just arrived here, gave Schulz an unexpected look, then looked at the boat and murmured.

"I just said it casually, but I didn't expect you to find him."

"How could there be another episode like this?" Schulz looked at Perelman in an unexpected way, with a surprised expression on his face. He smiled and said, "it seems I have to thank you."

Perelman: No, I said it. I just said it

"We stand here for the same purpose now, whether or not we casually say it or not," said Lu Zhou, clapping hands and laughing at the two old friends. "So, let's not waste our time on greetings and reminiscences. We have plenty of time for dinner."

"I agree," Schulz said jokingly, "I heard that Professor Lu has made new discoveries in ABC's conjecture. I bought the latest - and most expensive - flight, and it immediately flew over from North Rhine."

"I'm afraid the new discovery is not enough. It's just a little thought," Lu Zhou continued with a embarrassed smile. "It's still a 500 page paper that has to be renewed from the moon."

"The new paper of the moon?" I didn't expect that the paper would be the beginning of the discussion. Schultz raised his eyebrows slightly and said hesitantly, "forgive me, that's nothing to discuss. I proved it wrong with my collaborators a few years ago."

"I know, including your refutation of his paper, I have read it, and it is very good."

After clearing his throat, Lu Zhou picked up a marker pen from the table and went to the whiteboard beside him. After a pause, he continued, " Obviously, there are problems in his paper, and the problems are not small. There is no doubt about them. But the day before yesterday, when I was re studying his paper, I found something interesting

Although he had a look of disapproval on his face, Schulz, who had noticed that Lu Zhou had already taken up his pen, did not say his mind after thinking about it, but quietly waited for him to continue.

So did Perelman, whose face did not change much, but just stared at the pen in the hand of the boat.

Intuition told him that the land boat must have found something amazing, so Schulz would be invited here from Germany thousands of miles away to discuss.

Whether that means proof of ABC's conjecture or not, it is worth his attention.

In addition, his intuition told him.

Once he missed a moment, even with his mathematical ability, it's hard to say whether he can keep up with his amazing thinking speed

"Inference 3.12 is the core of the whole paper, which undoubtedly changes ABC conjecture from an abstract mathematical concept to a specific inequality related to elliptic curve."

"However, the root cause of the problem is also here -"

just when the land boat said the most critical moment, a dramatic scene suddenly happened.

A sound of fierce footsteps came from the corridor outside.

Soon, after a knock, the half closed door was opened.

When I saw the two exaggerated nostrils at the door, I was about to write down the first line of formula on the whiteboard, and the whole person was stunned.

But

It is obvious that someone is more surprised than him.

"Mochizuki"

"Schulz?"

On the sight of the two people, on the spot on the Leng there.

Gradually, the atmosphere began to get a little more subtle.

The big eyes stared at each other, and the expressions on the two faces stiffened.

After catching up with Wang Yuexin and walking to the door of the office, President Qin, who took a breath by holding the door frame, was about to introduce the visiting famous scholar of Kyoto University to Lu Zhou, and then noticed professor Schulz and Perelman standing in the office.

Thinking of the things that made a lot of noise in the mathematical world some time ago, the old man, who is familiar with the world, immediately smelled the smell of sparks in the air."Ha ha, no, I didn't expect you were all here..."

For the strange expression of landing on the boat, President Qin touched the back of his head, smiled sheepishly and coughed quickly.

"This is the new moon Well, if you talk, I won't introduce you. "

As soon as the voice dropped, the old man turned around and slipped away.
