The great mathematician who cracked the Riemann conjecture didn't look at the problem, just tore it to pieces, and then said disdainfully, "You are an insult to me! You are just a porter, what qualifications do you have to test my ability? If you want to investigate, you have to call out your director!"

"The director is busy! I don't have time to see you, either I'll let you in to find him when you make a question, or just stay outside the door!" The porter's psychological quality is excellent, his eyelids are not raised, he held the big tea jar and took a sip and said calmly, "If you don't do the question and yell here to affect the office order, I will call the security guard!"

When the mathematician heard this, his face changed three times, and finally he snorted angrily, squatted at the door and stopped talking; Lu Qiujian saw that there was no excitement to see, and regretfully walked in, went downstairs to lock the car, and went upstairs to find the office he said and knocked on the door according to Professor Zhang's instructions.

"Please come in!" said a middle-aged man's voice in the office.

Lu Qiujian pushed open the door and walked in, only to see a slightly fat man with glasses sitting inside, he took out the document from his bag and handed it over, "Hello, I am from Beijing Normal University, Professor Zhang asked me to send this document to you." ”

"Oh, thank you, you sit down first, I'll read it when I'm done with this!" the man took the file and put it on the table, his gaze turned back to the computer, and Lu Qiujian saw out of the corner of his eye that what appeared to be a math paper displayed on the computer screen.

He returned to the sofa at the door and sat down, and after waiting for a while, the man finally finished reading the paper; he picked up the document sent by Lu Qiujian and flipped through a few pages, and couldn't help but exclaim, "This time, your Beijing Normal University is in the limelight, if I hadn't gone to other places in the past few days, why would I have to go over to listen to this lecture, even if there is no place to stand! By the way, did Professor Zhang say anything when he asked you to send the documents over?"

"I didn't say anything, just let me send it to you!" Lu Qiujian replied.

"Oh, that's right! What do you call it? Professor Zhang's graduate student?" he remembered before he asked Lu Qiujian's name, "My surname is Lu, and I am a researcher here!"

"Hello Mr. Lu!" The researcher sounds inconspicuous, but in fact it is a senior title, the researcher of the Institute of Mathematics of the Chinese Academy of Sciences is divided into one to four levels, corresponding to the first to fourth level of professors in universities, and the first-level researcher generally must be an academician of the Chinese Academy of Sciences or an academician of the Academy of Engineering to be qualified; So he replied in a respectful tone, "My name is Lu Qiujian, and I am still in my senior year, not Professor Zhang's graduate student!"

"Oh, senior! Then you have to work hard, Professor Zhang's graduate student is not good-looking! Okay, I'll write you a reply letter of receipt of the documents!" Researcher Lu picked up the pen and said as he wrote, "Well, your name is Lu Qiujian? This name seems a little familiar? Wait, which Lu Qiujian are you?!" He looked up suddenly.

"Huh. Although my name is not special, it is not very common!" Lu Qiujian said with a smile.

"Oops! look at my reaction!" Researcher Lu slapped his forehead and smiled self-deprecatingly, apologizing as he spun out from behind the desk. "I just finished reading a paper, and my brain hasn't reacted yet, I'm really sorry to keep you waiting here for so long!" he took Lu Qiujian's hand and shook it.

Lu Qiujian also stood up, "Sometimes I see a good paper. I can't even take care of eating, and I'm embarrassed if you don't blame me for disturbing your train of thought!" he knew that this was the norm for mathematicians, and what kind of dissatisfaction would there be.

"Hi. You came to the Institute of Mathematics to make us shine! I saw that I had left you here for a long time, and I didn't pour you a cup of water! What do you want to drink? Tea or coffee?" Researcher Lu had read Lu Qiujian's papers, knew the weight of his articles, and did not dare to look down on the other party when he was young.

Mathematics is one of the most talented subjects, and there is a saying that there are two kinds of mathematicians, one is a genius like Euler, and the other is a hard work type like Hilbert. Even Hilbert, who was considered eighty points talented in Hardy's mouth, was not counted as a genius, and the harshness of mathematics on geniuses can be seen.

Researcher Lu knew that he was quite smart compared to others, but it was not worth mentioning compared to demons like Tao Zhexuan and Lu Qiujian, so he lowered his posture.

"If you are Pengqing, then our mathematics department of Beijing Normal University is a broken cave, not even a house!" Lu Qiujiana would ask him to pour tea for himself, and hurriedly grabbed the cup and took two cups of water from the water dispenser and put them on the coffee table.

"The mountain is not high, but if there is an immortal, it is famous! Even if the Department of Mathematics of Beijing Normal University is a cave, it is also the residence of the immortals!" This researcher Lu is also a wonderful person, and the relationship between the two of them has become much closer unconsciously.

The two of them chatted for a while about each other's research fields, and Researcher Lu looked at his watch and quickly got up, "Oh, I've been chatting for so long without paying attention, and the director is about to get off work! I'll take you inside to have a look, and you can get to know a few experts here, maybe we'll have more time to deal with in the future! I'll take you to recognize the door today!"

"Okay, then I'll trouble you!" This is a thing that is very beneficial to himself, Lu Qiujian is not hypocritical, and immediately followed Researcher Lu out of the office.

The first director of the Institute of Mathematics was Mr. Hua Luogeng, and several subsequent directors have also achieved good results, and now this is less than 40 years old, and he is already a well-known mathematician in the world.

He met with Lu Qiujian at a report meeting some time ago, and this time he had a special discussion on the part of Lu Qiujian's closing speech that involved his research field, and both sides gained a lot.

Coming out of the director's office, Researcher Lu took him to visit several authoritative figures, and didn't send him to the door until he got off work, "I'm really not polite to you, I really have something to do today! Next time, next time!", he refused Lu Qiujian's invitation to have a light meal with him, and went back to the office.

Lu Qiujian pushed his car and walked out of the door, and when he arrived at the door, he found that the great mathematician who had cracked the Riemann conjecture was still waiting there.

Today's visit seems to be a bit special? Looking at the expressions of the director and the other experts, it seems that there is some secret hidden? Until he returned to his room, Lu Qiujian was still pondering this question. (To be continued.) )
