There were hundreds of people standing on the apron.

"How come there are so many people?"

Pang Xuelin looked at the crowd on the apron in surprise.

Liu Tingbo also leaned over his head, looked at the scene outside the porthole, and said, "Professor Pang, they should all come to greet you."

“Welcome me?!”

Pang Xuelin is a little incredible.

This show is even higher than the Nobel Prize ceremony last year.

Can those nerds in the mathematics world do such a thing?

Liu Tingbo seemed to see Pang Xuelin's idea and said with a smile: "Professor Pang, you may have underestimated your influence in the mathematics community. Not to mention anything else, there are many mathematicians studying Ponzi geometry around the world today. The Ponzi geometry seminar in our school, young scholars in the mathematics community want to come in after squeezing their heads. There are only a dozen places every year. Now many young mathematicians regard you as their idol..."

Pang Xuelin nodded thoughtfully.

Although now in the outside world, ordinary people will immediately associate this name with lithium air batteries and the Nobel Prize after hearing Pang Xuelin's name.

But in the eyes of the mathematics community, Pang Xuelin is not doing his job properly.

Many mathematicians believe that if Pang Xuelin does not use lithium air batteries or superconductors, with his talent, it is entirely possible to achieve greater achievements.

"Some people even said that if Pang Xuelin concentrates on mathematics, he will hope to become the God of the mathematics community."

This sentence was first circulated from Faltings. This stubborn German old man said in an interview with the media that Pang Xuelin was another super genius that emerged in the mathematics community after Grothendieck, the algebraic geometry pope in the 20th century.

Then, he added: "It's a pity that this guy is not doing his job properly, otherwise he will be the God of the mathematics community."

After hearing this evaluation, Pang Xuelin could only shake his head and smile bitterly.

I don’t know if I can see this old man at this International Mathematician Conference.

The passenger plane slowly stopped on the apron, the aircraft cabin door opened, and the gangway was slowly connected to the aircraft.

Then, the flight attendant said, "Professor Pang, you can get off the plane."

Pang Xuelin nodded, and under the guidance of the flight attendant, he stood up and walked out of the plane first.

The crowd greeted on the apron immediately cheered.

Pang Xuelin walked down the gangway.

Two people walked towards him, one was tall and thin, with bald hair, and the other was erect and had a big belly, only about 1.6 meters tall. He walked and waved his way, looking a bit funny.

The bald old man stretched out his hand first and said, "Hello, Professor Pang, welcome to St. Petersburg. I am Marcelo Viana, chairman of the organizing committee of this St. Petersburg International Mathematicians Conference."

"Hello, Mr. Chairman."

Pang Xuelin shook hands with Marcelo Viana with a smile.

Immediately afterwards, he turned his eyes to another big belly old man and said with a smile: "Hello, Chairman Kenny."

The old man with big belly smiled and said, "Professor Pang, I finally hope for you."

This big-bellied old man is Carlos Kenny, a professor at the University of Chicago, a member of the American Mathematics Society, and is also the current president of the International Mathematics Federation.

Next, under the leadership of Marcelo Viana and Carlos Kenny, Pang Xuelin shook hands and said hello to the big guys who came to welcome him one by one.

Among them are some bigwigs from the International Alliance of Mathematicians, as well as Russian Deputy Minister of Foreign Affairs, Mayor of St. Petersburg and other political leaders.

At the same time, Perelman and Shinichi Mori, who were following Pang Xuelin, also shook hands with the people who were greeting each other.

Even compared to Pang Xuelin, Perelman was more popular when he returned to his home court.

After all, Perelman is also a long-standing big shot, and he is a native of St. Petersburg. Not long ago, he worked with Pang Xuelin to solve the Hodge's conjecture.

Especially in the mathematics community recently, Perelman is second only to Pang Xuelin in a sense.

If it were two years ago, Perelman might not have accepted such an occasion at all, so he ignored it and left.

However, after two years in Jiangcheng, he had been in contact with scholars from Ponzi geometry seminar from time to time, and his introverted personality became much better.

In addition, there is St. Petersburg, Perelman's hometown. When he returned to the familiar environment, Perelman reluctantly accepted the welcome ceremony.

Afterwards, everyone boarded the convoy arranged by the Russian side and headed straight to the hotel.

In the evening, the organizing committee of this International Mathematician Conference held a special banquet to entertain Pang Xuelin and his group.

After dinner, there was nothing to do next, so everyone went back to their room to rest.

The International Conference of Mathematicians will not open until August 8. In the past two days, mathematicians from all over the world will arrive in St. Petersburg one after another.

Everyone rested in the hotel for a night. The next morning, after eating the hotel's buffet breakfast, Pang Xuelin just returned to the room and the door was knocked by a bang.

Pang Xuelin ran to open the door and saw Perelman and Wangyue Shinichi standing at the door.

Shinichi Moon took the lead in speaking: "Pang, Grigori is going home. Do you want to go and have a look together?"

"Okay, wait for me."

Pang Xuelin laughed.

Soon, he finished packing and followed Perelman and Wangyue to refresh the building.

As soon as they walked to the hotel door, Pang Xuelin saw Zuo Yiqiu and Ai Ai walking hand in hand, talking intimately while walking.

Pang Xuelin was a little curious, and didn't know how these two girls looked at each other.

When Zuo Yiqiu was with Pang Xuelin, he rarely showed this state.

Most of the time she is more serious and has a bit of a heavy mind.

When she was in Jiangcheng, although her relationship with Yao Bingxia and Qi Xin was not bad, she was far from being so close.

On the contrary, when he was with Ai Ai, Pang Xuelin vaguely saw Zuo Yiqiu's nature being deliberately suppressed.

"Where are you going?"

Pang Xuelin said curiously.

Hearing Pang Xuelin's voice, both of them raised their heads.

Ai Ai smiled first and said, "Master, Sister Zuo and I are going to go out for a walk."

Zuo Yiqiu also asked, "Professor Pang, are you going to go out? Do you want me to follow me?"

Pang Xuelin smiled and waved his hand and said, "It's okay, just go with Zhou Chen. Today I will give you a day off. You can go out with Ai Ai. Remember not to come back too late."

"good."

Zuo Yiqiu nodded.

Ai Ai smiled and said, "Master, then we'll leave first."

As he said that, he pulled Zuo Yiqiu and left the hotel directly.

Pang Xuelin smiled and shook his head, and said to Perelman and Shinichi Wangyue beside him: "Let's go too."

Then, the three of them boarded the convoy waiting at the door.

This time when he went abroad, Pang Xuelin's security level was fully equipped with the travel specifications of senior leaders. Even the bulletproof cars he was riding on were airlifted from China.

Pang Xuelin didn't care. With his current ability, ordinary assassination did not pose a threat to him at all.

Soon, the car started and drove towards the neighborhood where Perelman had lived.

Twenty minutes later, the convoy stopped near an old community.

The architectural style of this community has a strong Soviet-era atmosphere. There are not many pedestrians around. Occasionally, someone passes by, and they will also look at Pang Xuelin and his group curiously.

The infrastructure near the community is limited, cracked asphalt pavement, fallen leaves all over the ground, and rusty bus stop signs, which look a bit dilapidated.

"Grigory, is this where you grew up?"

Pang Xuelin said a little curiously.

Perelman nodded, with a hint of remembrance on his face.

"Let's go in."

Perelman said.

Pang Xuelin nodded and said to Zhou Chen beside him: "You guys stay outside, I will go there with Grigori and Professor Shinichi Wangyue."

"But Professor Pang..."

Zhou Chen hesitated a little.

Pang Xuelin smiled and said, "Don't worry, our itinerary was reported to the Russian authorities yesterday. The safety here must have been screened. And aren't your Russian colleagues around?"

Seeing that Pang Xuelin was firm in his attitude, Zhou Chen could only nod helplessly.

Pang Xuelin, Perelman, and Wangyuexin entered this dilapidated neighborhood together.

What surprised Pang Xuelin was that Perelman did not take them home directly, but went to a small grocery store hidden in the corner.

The owner was a bearded old man with a red nose. He seemed a little surprised and surprised by Perelman's arrival.

"Grigory, I haven't seen you for a long time. I heard that you went to China. How are you doing recently?"

Perelman nodded and said, "I'm fine, Old Wade, give me a pack of black coffee, three rye bread, three red sausages, oh, by the way, another small bottle of vodka."
