Chapter 169

Gu Lu asked Bi Qi to leave first, and then left Ma Zhengxuan behind.

"Bring a chair over and sit down and talk."

Gu Lu asked Ma Zhengxuan to move a chair and sit down, then crossed his fingers and looked at Ma Zhengxuan with concern, "Are you still getting used to it after entering university?"

Ma Zhengxuan put his hands flat on his knees and nodded in reply, "At the beginning, I felt that there was a big difference between college life and high school life, but now I have adapted to it."

"What are you busy with now, I mean, besides studying?" Gu Lu's smiling eyes fell on Ma Zhengxuan.

From Bi Qi's few words some time ago, Gu Lu knew that Ma Zhengxuan had been a frequent visitor to the library since he entered university.

After entering college, although he no longer had the constraints of teachers, Ma Zhengxuan still followed the high school rhythm and spent most of his time reading and studying every day.

And it's even harder than high school.

In terms of study, Gu Lu doesn't have to worry about Ma Zhengxuan at all.

As for other aspects, Gu Lu, as Ma Zhengxuan's high school teacher, naturally has to pay special attention to him.

"I'm currently working as a tutor." Ma Zhengxuan lowered his head and answered.

"Tutor?" Gu Luqing asked.

"Well, I was introduced to me by a senior in the work-study club I joined. It mainly tutors a senior girl in mathematics and physics." Ma Zhengxuan answered truthfully.

Gu Lu understood instantly.

It is quite common for Yan university students to become tutors.

Especially the freshmen who have just entered Yenching University are hot spots in the tutoring market, and are the targets of countless high school senior parents competing for them.

After all, every student who can get into Yan University must have top-notch grades in high school.

As for freshmen, because they have just experienced the college entrance examination, their understanding of the knowledge of senior high school students is even deeper than that of most high school teachers.

The price of hiring a student as a tutor is lower than hiring a professional teacher as a tutor, and it is more effective.

Gu Lu knew Ma Zhengxuan's family situation.

At that time, because Ma Zhengxuan helped Haicheng City win the title of top scorer in the college entrance examination, the Haicheng City Education Bureau and Haicheng No. 1 Middle School gave Ma Zhengxuan a total of 150,000 yuan in cash rewards.

One hundred and fifty thousand yuan.

Even in a high-consumption city like Yanjing, 150,000 yuan is enough for Ma Zhengxuan to survive four years of college.

But obviously, Ma Zhengxuan did not plan to use all of the 150,000 yuan on himself.

Gu Lu opened his mouth and wanted to say something, but in the end he could only sigh softly.

"What's the price of your tutoring?" Gu Lu asked, rubbing his eyebrows.

"One hundred and fifty yuan an hour. I teach three hours a week in total. Four hundred and fifty yuan is enough for my week's expenses, and I can still have some left over to pay home." Ma Zhengxuan showed a rare happy smile.

This price is considered a normal price.

It is much better than some college students working part-time to do hard work.

But this rate of making money is still a bit slow.

Gu Lu can recommend many places to make money, but Ma Zhengxuan's current mathematics level is not yet up to par.

Gu Lu forced it on, not saying whether the other side would agree, but Ma Zhengxuan might not be willing.

So, let's wait.

It is estimated that Ma Zhengxuan will be able to grow up in another half year.

Gu Lu continued chatting with Ma Zhengxuan.

Among them, the issue that is emphasized again and again is health!

Staying up late is a bad habit!

Although Gu Lu, a teacher, also stayed up late, it did not affect his serious face and warned Ma Zhengxuan to stay up less late in the future!

Staying up late will not only affect your health, but may also cause kidney failure, chicken weakness, etc.

It can also cause hair loss and reduce the chance of losing your virginity.

In addition, Gu Lu also asked Ma Zhengxuan to pay attention to his diet.

Don't just go vegetarian to save money, eat more meat to replenish your body.

Ma Zhengxuan looks like this now, and Gu Lu feels that he is even thinner than when he was in high school.

As for meat, Gu Lu recommended to Ma Zhengxuan the "Call a Chicken" from the Farm Restaurant.

He crows a chicken every now and then to enjoy himself. Gu Lu has become accustomed to this kind of life during this time.

…………

Time flies and it’s early December.

It was another Monday. Gu Lu finished his morning class and returned to the office after lunch. As soon as he sat down, he received a message from Su Xi.

Su Xi: "Teacher Gu, there is a lecture given by Wangjing Shinichi recently. I have received the invitation letter. Will you go?"

A photo is attached below.

In the photo are two invitations, with red covers and the contents inside are all in Japanese.

Gu Lu had studied Japanese for a period of time, so he could clearly understand what was written on the invitation letter.

Time: 17:00 on December 8, 2017

Venue: Tokyo University Auditorium

Speaker: Wangjing Shinichi

Lecture name: "Elaboration of Teichmüller Theory of Interuniverse Based on ABC Conjecture"

Many thoughts flashed through Gu Lu's mind instantly.

Shinichi Mochii, a professor at the University of Tokyo in the island nation, is one of the representatives of the mathematical community in the island nation.

His most important achievement is his 512-page paper proving the ABC conjecture.

Even though, because Mochii Shinichi's 512-page paper is too obscure and difficult to understand, no international mathematical organization has publicly announced that Mochii Shinichi's proof process is correct.

But what is undeniable is that in the field of ABC conjecture, Mochii Shinichi is indeed the first person.

Just like the status Chen Jingrun has achieved in the field of Goldbach's conjecture.

However, for Gu Lu himself, this lecture did not attract him much.

During this period of time, because of Su Xi, Gu Lu attended many academic lectures given by big names.

But most of them are domestic, such as Academician Zhang’s report on the hypothesis of the unity theory of differential geometry, Academician He’s latest progress on the Kakutani conjecture, etc.

The only time I went abroad was to Malaysia to listen to a report on the latest achievements of a famous Asian mathematician. I flew back the same night after listening to the report.

After several lectures, Gu Lu gained a lot.

Since Su Xi didn't know any specific fields of mathematics, when choosing lectures, she always chose speakers with higher titles, taking into account the time factor.

There are no restrictions on the specific branch of mathematics to which the report content belongs.

Therefore, Gu Lu attended lectures on various branches of mathematics, not just the number theory and geometry that he majored in.

For example, algebra, topology, function theory, functional analysis...

Professor Wangjing Shinichi's ABC conjecture can be regarded as a problem in the direction of number theory, which corresponds to Gu Lu's main research direction.

But after thinking for a few seconds, Gu Lu decided not to attend the lecture.

First, the location is too far away. It takes a lot of time to go back and forth in the island country.

The second is the content of the lecture, which is the Teichmüller theory of the universe, which is Shinichi Mochi’s 512-page paper.

To be honest, Gu Lu had not read that long paper, so naturally he had no understanding at all of the Teichmüller theory of the universe that was mainly explained in his paper.
Chapter completed!
