The annoying thing for the little girl did not happen.

Because that night, she couldn't sleep after tossing and turning, and finally took the initiative to ask her sister on WeChat, and went out to watch a movie together the next night.

As for Lu Zhou, there was no special arrangement on this day, he sat in the office as always, and did what he usually did step by step.

He used to celebrate the festival in Princeton, but it doesn't seem to have happened since he returned home.

Of course, this may also be due to the fact that there are no people who can celebrate the festival together.

After all, most of this kind of "imported" foreign festivals will be labeled as Valentine's Day, and for people who don't have an object, on this day, of course, it is as far away as possible from a crowded place.

But at this moment, a movie ticket was stuffed in front of him.

"Are we going to the movies?"

Glancing at the movie ticket, Lu Zhou, who raised his head, saw Senior Brother Luo, who was holding the desk with his right hand and smiling, looking at him wildly, as if he was madly hinting at something.

Seeing this expression, Lu Zhou hesitated slightly.

This seems to mean ......

Hinting that he refuses?

In an uncertain tone, he spoke.

"I ...... Not available? ”

"Ah...... You are actually not free, I also specially bought two tickets, and I am going to invite you to watch a movie," he put his right hand on his head and grabbed his hair exaggeratedly, Luo Wenxuan's eyes continued in that exaggerated tone while looking around the office for the figure of Assistant Kong, "What a headache......

Lu Zhou: "......"

No, no......

He almost threw up.

This guy is not a junior brother who has never seen the world, how could he come up with such a hard old stalk to ask girls out to watch movies. Even Lu Zhou, who has never seen the world, is about to cry stupidly by this guy's routine.

Crazy hinted for a while, Assistant Kong, who was sitting next to the window, was still indifferent, and didn't even notice him at all, just when Luo Wenxuan was about to despair, it happened that Assistant Lin walked in from outside.

"Midnight show?" Hearing the movement here, Lin Yuxiang, who came over and looked at the movie ticket, suddenly glanced at Luo Wenxuan suspiciously, then at Professor Lu who was sitting behind the desk, and finally looked at Luo Wenxuan with a strange expression and continued, "You invite Professor Lu to watch a movie...... What do you buy a midnight show for? ”

"Two big men watch the midnight show together, it's not a premiere yet......"

Hearing this, Lu Zhou, who was drinking tea, almost didn't squirt out a mouthful of tea.

Damn, this guy is a werewolf!

The first time you ask someone to buy a ticket to a midnight show?

Luo Wenxuan, who was standing next to the desk, was also scorched by this sentence, and hurriedly explained.

"No, this one...... I saw that the midnight show was cheaper, so I bought it. ”

However, it is useless to explain any more.

What's more, this explanation is too blunt.

A professor who has returned to China with millions of scientific research start-up funds will care about the difference of ten or twenty yuan?

Just kidding!

Thinking of this, this guy always runs to Professor Lu's office when he has nothing to do, and he doesn't do anything after he comes, at most he just rubs a cup of tea and drinks.

Don't......

This flustered sentence had just come out, and Luo Wenxuan immediately regretted it.

However, at this time, it is obviously too late to regret it.

He had noticed that several people in the office were looking at him a little unnaturally.

Especially the most painful thing for him was the assistant Kong, who was surprised with a hint of surprise, and it almost poked at his heart, and he was about to cry.

If you're interested, you're fine, but the problem is that I'm not that kind of person!

Lin Yuxiang hit the nail on the head and said: "No, you all have the money to renovate the office, and you don't have the money to reimburse the invoice of the movie theater?" ”

Luo Wenxuan: "......"

At this moment, he didn't want to say a word.

Looking at Professor Luo, who was silent, Lin Yuxiang's eyes rolled, and he suddenly pursed his lips and smiled.

"Otherwise, sell me the ticket, and I'll accompany Professor Lu to see it."

At this moment, Luo Wenxuan, who just wanted to clarify the misunderstanding, naturally did not have any opinions, and decisively sold his teammates without saying a word.

"Good! I'm okay with that! ”

Han Mengqi: "!!??? ”

Seeing that the office was in a mess, Lu Zhou coughed heavily.

"You ...... I don't think you have asked my opinion yet. ”

Yingying's eyes flashed with anticipation, Lin Yuxiang immediately looked over to this side, and clapped his hands together on his chest.

"That ......"

Lu Zhou: "I'm not free, I'm not going." ”

Lin Yuxiang: "......"

Kong Jie, who couldn't hold back and was sitting by the window not far away, burst out laughing.

That smile is like a spring breeze, as if it has blown away the winter snow.

Feeling that the neighborhood was quieter, Lu Zhou glanced at Senior Brother Luo, who was standing opposite the desk, and looked at the appearance as if he had been petrified, and shook his head helplessly.

This guy ......

The eyes are almost on people's bodies......

……

Movies are impossible to watch.

Not to mention the midnight show.

Nothing but math was worth keeping his eyes open before twelve. Even if you take 10,000 steps back and add another one, you can only add one physics at most.

The rhythm of work was not disrupted because of the episode caused by the two movie tickets, and he was busy until dusk, when the people in the office were basically finished, and Lu Zhou stretched his waist and stood up from his desk.

However, less than two seconds after standing up, a WeChat call hit his mobile phone.

took out his mobile phone and saw that the video request was sent by Xiaotong, so Lu Zhou pressed the button to connect.

As soon as the video was connected, the familiar face instantly came into view.

"Dude! I miss you so much! ”

A crisp voice came from the other end of the video, and Xiao Tong, who was wearing loose home pajamas, excitedly leaned in front of the screen of her mobile phone.

I haven't seen each other for almost a year.

Compared with the last time they were separated, the little guy looked like he had lost a little weight, but there were no other obvious changes.

Looking at his sister on the other end of the video, Lu Zhou smiled and said.

"Just look in the mirror if you think about it, anyway, we are also born by a mother, even if it is not carved in a mold, it is almost a little similar."

Xiaotong: "Bah, don't try to take advantage of me!" ”

Looking at Xiao Tong, who was trying his best to resist, Lu Zhou smiled and didn't speak.

Although Xiaotong is reluctant to deny it vigorously, what's the use of denial? Of course, he still has a good idea of who took advantage of whom.

After all, didn't Lu Xun once say that a girl with a handsome and charming brother usually doesn't disappoint the audience too much.

"Say, why did you suddenly think of calling your brother?"

Hearing Lu Zhou's question, Xiao Tong's eyes on the other side of the video rolled, and he instantly changed to a flattering expression, and said in a coquettish tone.

"Brother, it's New Year's Day in a few days~"

"Hmm."

"I want a gift!"

"No problem," Lu Zhou smiled, "Say, whatever you want, as long as I can afford it." ”

"Hee-hee, okay, then I'll send you the gift list!"

As soon as the words fell, there was a soft ding dong sound from the computer resting on the table, and then a string of bubbles popped up in the lower right corner, and Xiao Ai came out at the right time.

[Master, there is a new mail ~ (????????????)???? 】

Appetite for this?

So much so that I have to send an email......

But Lu Zhou is not embarrassed, with his current savings, let alone buying some expensive bags or clothes, even if he buys a smaller investment bank for her to practice, it is no problem.

The right hand holding the mouse double-clicked, and Lu Zhou clicked on the mailbox and looked at the title of the email.

However, the moment he saw the title of the email and the content of the attachment, the whole person was slightly stunned.

【Analysis of the Impact of Welfare Policy on Macroeconomy Based on Bewley Model】

He'd heard a little bit about the Bewley model, as if it was a Nobel laureate in economics when he was still in Princeton, and it was said to be one of the most important, cutting-edge, and difficult topics in macroeconomics. The advantage is that it is intuitive in the numerical sense, and the disadvantage is that it is cumbersome to solve.

For example, it would take one to two hours to run Krusell & Smith's Bewley model with aggregate volatility in Fortran90. Designing the entire mathematical model can take years from a well-known scholar.

Compared with this kind of macroeconomic research, the topics of those mathematical modeling competitions are all pediatrics.

However, although he had heard a few things about the Bewley model, he didn't know much about it, after all, like most professors in pure mathematics at Princeton, he was not very interested in money.

At most, just a little bit of interest when it comes to spending money......

Suddenly realized something from Xiao Tong's expectant eyes, Lu Zhou, who withdrew his gaze from the email, calmed down, and immediately said angrily.

"Write your homework!"

MMP！

A Fields Medal winner of Temeow ran to help master's students write homework, and passed it on or not?

"Brother~!"

Lu Zhou said expressionlessly: "It's useless to be coquettish, I don't eat this." ”

Xiaotong said with a sad face: "But this is too difficult, and I am not a math major...... Let me do such a difficult subject, I really can't help it, so I asked you for help. ”

Of course, Lu Zhou wouldn't believe her nonsense, and shook his head.

"How difficult can a master's thesis be."

"Don't believe it, look at the attachment! If you read it, you will know if it is difficult or not! ”

It was really hard to stand Xiao Tong's soft grinding and hard bubbles, and Lu Zhou, who sighed, glanced at the time in the lower right corner of the computer, and finally reluctantly agreed to just take a look.

However, as soon as he downloaded the attachment and took a look at it, a strange color appeared in his eyes.

Although he doesn't know much about the part of economic theory, as far as the mathematical model is concerned, the problems shown in this annex are indeed not at the level of a master's student.

Even if he is asked to do it by He Changwen, the chief disciple of Jinda, it will probably take a lot of time, and it may not be able to make this model beautiful.

"Your tutor is kind of interesting, this kind of homework...... Without putting a lot of effort into functional analysis, even if you just master the principles of mathematical modeling, it may not be easy to get this thing done. ”

Xiaotong pouted and said, "I'll just say it, is this a human thing?" ”

Lu Zhou: "Are you sure this is the task assigned to you by your mentor?" ”

Xiao Tong nodded vigorously: "Hmm! Or else? I was crazy to choose such a difficult topic for my graduation thesis. ”

Lu Zhou thought for a while and said, "That's it, it's definitely not okay for me to help you write your homework, this is your paper." But there's nothing wrong with co-writing, you complete the economic theory part, and I finish the mathematical principles part. ”

"Really?! Dude, did you agree?! Great, my dissertation was saved! mua！ Jumping up excitedly, Xiao Tong, who hugged the mobile phone screen and kissed it, lay back on the sofa, and said with a smile, "Brother is so good!" I love you to death! ”

"Fuck off, don't be skinny with me, and besides, I have a request."

Holding the pillow and sitting up from the sofa, the elated Xiaotong said with a smile: "Say it, I will promise you any request, do you need me to help you introduce your girlfriend?" In the office next door to us, there are a lot of beautiful young ladies with blond hair and big breasts. ”

"This doesn't have to be," Lu Zhou coughed lightly and continued, "...... After the paper is completed, you can submit it directly, and you can do whatever you want, but the corresponding author will hang my name. ”

Hearing Lu Zhou's request, Xiao Tong was slightly stunned, and suddenly made a sad face.

"But...... I'm worried that the tutor won't agree. I'm about to graduate, and if he gets my diploma, I'll be miserable. ”

In the management of the academic world, students are working for their tutors on a day basis.

Papers are published by themselves without going through their supervisors.

Dare to play like this, I don't want a graduation certificate.

expected Xiao Tong to say this, but Lu Zhou didn't care much about his expression.

I saw him smile faintly and only said one word.

"You let him try."
