Chapter 875

What bothered the little girl didn't happen.

Because that night, she couldn't sleep over and over, and finally took the initiative to ask her sister on wechat, and went out to see a movie together the next night.

As for the land boat, there was no special arrangement on this day. As always, I sat in the office and did what I would normally do.

He used to do as the Romans did when he was in Princeton, but it seems that he hasn't had it since he returned home.

Of course, it may also be because there are no people who can have this festival together.

After all, most of the foreign festivals are labeled as Valentine's day. For those who don't have an object, it's certainly a good day to be as far away from people as possible.

But at this time, a movie ticket was put in front of him.

"Going to the movies together?"

Looking at the movie ticket and looking up at the boat, I saw that elder martial brother Luo, with his right hand holding his desk and a smile on his face, was winking at him, as if he was indicating something.

Seeing this expression, Lu Zhou hesitated a little.

It's like

Implying that he refused?

In an uncertain tone, he said.

"I No time

"Ah You are not free, and I bought two tickets specially to invite you to the cinema. "Action flashily put his right hand on his head and grabbed his hair. Luo Wenxuan's eyes searched for assistant Kong in the office, and continued to say," it's a headache... "

Lu Zhou: "..."

No way, no way

He can't help but puke.

This guy is not a new brother who has never seen the world. How could he come up with such a tough old guy to ask a girl out to see a movie. Even if I haven't seen the world's land boat, I'm going to cry because of this guy's routine.

Crazy hint for a while, assistant Kong sitting next to the window was still indifferent, even didn't notice his side. Just when Luo Wenxuan was about to despair, assistant Lin came in from outside.

"Midnight?" Hearing the news here, Lin Yuxiang, who has seen the movie tickets, suddenly takes a suspicious look at Luo Wenxuan, and then at Professor Lu, who is sitting at the back of his desk. At last, he looks at Luo Wenxuan strangely and continues, "please invite Professor Lu to see the movie What do you want for midnight? "

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

Hearing this, the boat was drinking tea. Almost no tea came out.

Manger, this guy is a werewolf!

Buy tickets for midnight on your first date?

Luo Wenxuan, standing at his desk, was also given this sentence to Lei De's outside Jiao and inside Nen, explaining in a hurry.

"No, this I think midnight is cheaper. I'll buy it. "

No more explanation, however.

What's more, the explanation is too rigid.

A thousand returned professors with a research start-up fund of one million will care about the difference of ten to twenty yuan?

Are you kidding!

Then I think that this guy always runs to Professor Lu's office when he has nothing to do. He doesn't do anything when he comes. The most is to rub a cup of tea.

Don't you

This flustered words just export, Luo Wenxuan immediately regretted.

But it's too late to regret.

He has noticed that the eyes of several people in the office are not natural.

In particular, assistant Kong was the one who hurt him most. With an unexpected sight in his surprise, he just poked at his heart, and he was almost crying.

If there is interest in this area, it's enough, but the problem is that I'm not that kind of person!

Lin Yuxiang said to the point: "not at all, you have money to decorate the office, but not to reimburse the cinema's invoice?"

Luo Wenxuan: "..."

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

Looking at the silent Professor Luo, Lin Yuxiang's eyes turned and suddenly chuckled.

"Otherwise, I'll sell the ticket to you. I'll go with Professor Lu to see it."

At this moment, Luo Wenxuan, who just wants to clarify the misunderstanding, naturally has no opinion. Without saying anything, he sold his teammates decisively.

"Good! I have no problem! "

Han Mengqi:

Seeing the office in a mess, the boat coughed heavily.

"You I don't seem to have asked for my opinion. "

Yingying's eyes twinkled with expectation. Lin Yuxiang looked right here and clapped his hands together in front of his chest.

"Then..."

Lu Zhou: "no time, no way."

Lin Yuxiang: "..."One didn't resist, and Kong Jie, who was sitting near the window, chuckled.

That smile, like the spring breeze, seems to blow away the snow in winter.

Feeling quieter nearby, Lu Zhou looked at elder martial brother Luo standing opposite his desk, looked at the picture like he had been petrified, and shook his head helplessly.

This guy

My eyes are growing on others

……

It's impossible to see a movie.

What's more, it's midnight.

Apart from mathematics, there is nothing worthy of him to keep his eyes open before 12 o'clock. Even if you take ten thousand steps back and add another one, you can only add one physics at most.

There was no interruption caused by those two movie tickets, which disrupted the work rhythm. Until dusk, people in the office had basically gone. Lu zhoucai stretched himself and stood up from the desk.

However, within two seconds of standing up, a wechat call reached his mobile phone.

Touch the mobile phone and see that the video request is from Xiaotong. Then, Lu Zhou presses the connect button.

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

"Brother! I miss you so much! "

The clear and crisp voice came from the other end of the video. Xiaotong, wearing loose pajamas at home, excitedly gathered in front of the screen of the mobile phone.

I haven't seen you for nearly a year.

Apart from the last time, the little guy didn't see any obvious changes except a little thin.

Looking at his sister at the other end of the video, Lu Zhou said with a smile.

"If you want me, just look in the mirror. Anyway, we are born of a mother. Even if it is not carved by a mold, it is almost like a God."

Xiao Tong: "bah bah bah, don't try to take advantage of me!"

Looking at Xiaotong who resisted strongly, Lu Zhou smiled and didn't speak.

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

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

"Come on, why do you suddenly want to call your brother?"

Hearing the question from Lu Zhou, Xiao Tong's eyes on the opposite side of the video changed into a flattering expression and said in a coquettish tone.

"Brother, it's new year's day in a few days ~"

"well."

"I want a gift!"

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

"Hee hee, it's agreed. Then I'll give you the gift list!"

As soon as the voice fell, the computer on the desk heard a soft Ding Dong. Then a string of bubbles popped up in the lower right corner, and AI came out at the right time.

[host, do you have any new mail?]

do you have such a big appetite?

It's too much email

But there is no problem for Lu Zhou. With his current savings, let alone some expensive bags or clothes, it's OK to buy a small investment bank to practice for her.

Hold the right hand of the mouse and double-click it, and then the boat opens the mailbox and looks along the title of the email.

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

[Research on the impact of welfare policy on macro-economy based on the Bewley model]

he has heard a little about the Bewley model. It seems that when he was still in Princeton, a Nobel Prize winner talked with him about this thing, which is said to be one of the most important, cutting-edge and difficult topics in macro-economy. The advantage is that it is intuitionistic in numerical sense, and the disadvantage is that the solution is tedious.

Taking the mainstream computer as an example, it takes one to two hours to run Krusell & Smith's Bewley model with overall fluctuations in Fortran 90. It may take years for a well-known scholar to design the whole mathematical model.

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

But although I've heard something about the Bewley model, I don't know much about it. After all, like most professors in Princeton who study pure mathematics, he is not very interested in money.

At best, I'm just a little interested in spending money

Suddenly, she realized something in her expectant eyes, and Lu Zhou, who took back her eyes from the mail, calmed down and said angrily.

"Write your homework!"

MMP！

One of my fields prize winners of TEMAO ran to help the master students with their homework. Did they lose their share?

"Brother ~!""It's no use being coquettish, I don't want to eat this set," said Lu

"But it's too difficult. I'm not a math major I can't help but ask you for help when I have such a difficult task

Of course, Lu Zhou didn't believe her story and shook her head.

"How hard can a master's thesis be?"

"I don't believe you. Look at the attachment! You'll see if it's difficult! "

It's hard to stand Xiaotong's hard and soft bubbles. After sighing, Lu Zhou looks at the time at the bottom right corner of the computer, and finally reluctantly agrees to take a look.

But just after he downloaded the attachment and looked at it, there was a strange color in his eyes.

Although he doesn't know much about the theory of economics, the problems shown in this annex are not really solved at the level of a master's degree.

Even if he Changwen, his chief disciple in JINDA, is allowed to do it, it will probably take a lot of time, and it is not sure how beautiful the model is.

"Your tutor is a little interesting. This kind of homework I don't have to work hard on functional analysis. Even if I have mastered the principle of mathematical modeling, I'm afraid it's not easy to get this thing done. "

Xiao Tong pursed and said, "I'll tell you, is this what people do?"

Lu Zhou: "are you sure this is the task assigned to you by your tutor?"

Xiao Tong nodded his head hard: "Hmm! Otherwise? I was crazy to choose such a difficult topic for my graduation thesis. "

Lu Zhou thought for a moment and said, "well, I can't help you with your homework. This is your paper. But there's no problem in CO writing. You complete the theory of economics, and I complete the principle of mathematics. "

"Really?! Brother, you agree?! Great, my graduation thesis is saved! mua！” Excitedly jumped up, hugged the mobile phone screen and kissed Xiaotong, lying back on the sofa, and said with a smile, "my brother is wonderful! I love you so much! "

"Get out of my skin, and I have a request."

Holding the pillow, he sat up from the sofa, and Xiaotong said happily, "let's talk about it. I'll promise you anything. Do you need me to introduce your girlfriend? We are next door to the office, but there are many beautiful ladies with blonde hair, blue eyes and big breasts

"That's not necessary," Lu Zhou continued, coughing softly When this paper is finished, you can submit it directly. You can do whatever you like for one work, two works and laboratory signature, but the corresponding author bears my name. "

Hearing Lu Zhou's request, Xiao Tong is slightly shocked, and suddenly looks sad.

"But I'm afraid the tutor doesn't agree. I will graduate soon. If he cards my diploma, I will be miserable. "

In the management of academic circles, students work for their tutors in vain.

The paper is not published by the tutor.

Dare to play like this, I don't want my diploma.

I expected Xiao Tong would say that, but Lu Zhou didn't care much.

I saw him smile lightly, only said a word.

"You let him try."
