In the days since, Lu Zhou has basically been around Jinling University.

Either visit the old professors I knew before, or stay in the hotel and study the NS equation.

After returning to China, he had so many things to do on socializing that he didn't have much time to do math problems.

And now, he finally has that time to continue to delve into academic problems.

In addition to studying these questions behind closed doors in the hotel, Lu Zhou occasionally went back to the library of Jinda to sit and find the feeling he had when he was a student.

It is this feeling that allows him to think from a completely different perspective than usual, and this often brings him unexpected inspiration.

A week passed like this, and soon it was January 18th.

Two days before the wedding, the friends of 201 finally got together again after a year.

It is still a small fish village at the school gate.

A pot of grilled fish was ordered, and four people served beer on the table.

While drinking, the four lads braged nonsense.

"Elbow, I'll toast you first." Raising a glass and touching Lu Zhou, Liu Rui continued in a free and easy tone, "I saw you on the news by chance a few days ago, and I bragged to the senior sister in the laboratory, saying that we slept together. At first she didn't believe it until I pulled out the picture. This cup, firstly, congratulations on winning another national award, and secondly, I also thank you for making me pretend to be a force in front of my senior sister. ”

Almost choked on this sip of beer, Lu Zhou coughed dryly: "...... You're welcome, next time remember to change to a less misleading statement. ”

I have to say that after being admitted to Yan University as a graduate student, Liu Rui's mentality has changed a lot.

If it was before, when he saw Lu Zhou's appearance in the news broadcast, even if he didn't turn off the TV, he would have been depressed for a while.

But now, he has been able to handle it calmly and read the news with a blank face.

From not understanding what Lu Zhou was studying at first, to now he can't even understand what awards he has won, Liu Rui has learned to face the growing gap between the two.

Of course, if you want to ask if you are envious......

That must still be envy!

Lu Zhou: "By the way, who is your mentor at Yan University?" ”

Liu Rui thought for a moment and replied, "Academician Wang Xiping." I'm following him on a partial differential project. ”

"Wang Xiping? Academician Wang is also working on the direction of partial differentiation? ”

Lu Zhou didn't expect that Liu Rui's mentor, he happened to know him.

Liu Rui nodded: "Yes, but his research is more applied than pure mathematics." How? You haven't been studying number theory lately, but you've started to study partial differential? ”

Lu Zhou: "Sort of. ”

Liu Rui asked with interest: "Oh? What topics. ”

Lu Zhou smiled embarrassedly: "This, let's not talk about it." ”

Liu Rui waved his hand indifferently: "It's okay, my heart is strong enough now, just say it." ”

Lu Zhou: "NS equation." ”

After being silent for a while, Liu Rui spoke a little reluctantly: "...... Existential and smoothness problems of the solution of the NS equation? ”

Lu Zhou nodded: "Hmm." ”

Liu Rui: "......"

MMP！

The millennial conundrum.

How can there be such a big gap between this man and man?

Glancing at Liu Rui, who was depressed, Huang Guangming coughed lightly: "Let's talk about some light topics." ”

Shi Shang also nodded with a confused expression: "Agree." ”

After that, the four of them didn't talk about their studies anymore.

After all, the direction of development is different now, even if you want to talk, you can't talk together, and the more you talk, the more shocking it is.

Huang Guangming has not changed much from before, or the only thing that has changed, probably is that now, even when he is not smiling, he still gives people a feeling of cheapness.

Liu Rui looked a little tanned, and he looked much stronger than before. According to him, it's because of playing basketball. He never played basketball when he was an undergraduate, but he didn't expect to start playing now after he went to Yan University.

As for Shi Shang, he is probably the most changed of the four. may have been polished by society, and he has completed the transformation from a boy to a man, and his whole temperament looks much more mature.

According to Huang Xiaobei's words, it is the feeling of "leaving some scum to be a director, and wearing glasses to sell insurance".

Speaking of what has happened in the past year, Shi Shang can't help but feel emotional.

After graduating, the pace of life did not go as he expected, or deviated from the track he planned from the beginning.

Originally, he planned to work part-time to save a sum of money, then do a small business, and then buy a wedding house, but by that time, Wang Yajing had just finished three years of master's degree, and the two got married and got a certificate naturally.

As a result, less than a year after graduation, someone died.

The little life in Yajing's belly completely disrupted Shi Shang's original arrangement.

Not only that, but after working hard in Jinling for almost a year, he finally failed to save much savings, opened a small shop in Jinling, and lived the petty bourgeois life of his dreams.

But the good news is that in the end, he still bought a wedding house in the city.

Although, not by his own hands, but by the patronage of his father and mother......

“…… I don't know what else to say, as a brother, I just want to say one thing, my lessons are here. When you have a girlfriend in the future, be sure to take safety measures. In any case, don't kill anyone. ”

While sipping wine, Shi Shang poured bitter water from his stomach on his three roommates.

However, Lu Zhou, Huang Guangming and Liu Rui glanced at each other and saw a little strangeness in each other's eyes.

Finally, it was Huang Guangming who interrupted him.

"Phineas."

Shi Shang burped: "What's wrong?" ”

Huang Guangming: "Why do I always feel ......?"

Liu Rui: "...... You're pretending. ”

Lu Zhou didn't speak, just nodded silently in agreement.

Shi Shang touched his nose and smiled embarrassedly.

“…… What are you pretending to be forced, I'm not an elbow, do I look like the kind of person who can pretend to be forced? ”

Huang Guangming: "......"

Liu Rui: "......"

Lu Zhou: ???

The meal was eaten until 8 p.m.

I didn't move a few chopsticks to the dish, but I was full of wine.

Originally, the three of them planned to join forces to bring down Shi Shang, but unfortunately, with Liu Rui, they were destined to have no chance.

In the end, the first one to stop was still Liu Rui's kid.

As before, I saw him drinking and suddenly the whole person fell on the table with a bang, and then there was no movement.

When they came, Huang Guangming and Liu Rui were in Shi Shang's car, but now in this situation, it is obvious that no one can touch the steering wheel.

In desperation, Lu Zhou had no choice but to call Wang Peng and ask him to help drive him and send Shi Shang and them back to the Purple Mountain Hotel.

Until the days after the wedding, Huang Guangming and Liu Rui lived there.

Before getting into the car, Shi Shang, who was drunk, patted Lu Zhou's shoulder.

"The wedding the day after tomorrow, please!"

Shi Shang: "I'm talking about the best man. ”

Lu Zhou: "......?" ”

So what's not?

What else can it be if it's not the best man?
