For the rest, it's not a short time.

Chen Zhou is very honest and is watching a movie with Yang Yiyi.

As for the game......

What game?

Played the game before?

Can I play games on the plane?

Chen Zhou selectively forgets.

However, when the hypnotic duo was staged together, Chen Zhou was still a little unbearable.

No way, taking a plane and watching a movie is too sleep-inducing.

Chen Zhou sometimes can't figure it out, whether it's a car, a plane, or a movie, doesn't there always be a sound?

Especially the planes and cars, they are all quite noisy.

Why can it help you sleep?

Why are you so sleepy?

Chen Zhou handed the tablet to Yang Yiyi, took off the headphones, and got up to go to the toilet.

Wash your face first and keep your energy up.

Why don't you try thinking about math?

Regarding the weak conjecture of Goldbach's conjecture, don't you still have a few questions, don't you understand?

Although the weak Goldbach conjecture was thoroughly proved by Harold researcher at the École Normale Supérieure in Paris in 2013.

But don't you still have a few points, do you have some doubts?

Just take advantage of this time to think about it?

Chen Zhou, who had made up his mind, returned to his seat again.

Although she was still wearing headphones in her ears and her eyes were still looking at the screen of the tablet, Yang Yiyi was still snuggled in her arms.

But when the sleepiness struck again, Chen Zhou let his thoughts fly.

"The weak Goldbach conjecture says that any odd number greater than 7 can be expressed as the sum of three odd prime numbers ......"

"A prime number here can be used more than once......"

Chen Zhou thought about it, and his eyes became erratic.

And Yang Yiyi, who was nestled in Chen Zhou's arms, didn't notice Chen Zhou at this moment, and he didn't know where his mind had gone.

When she saw the hilarious plot in the movie, she couldn't help but laugh while watching Chen Zhou's reaction.

At first, Yang Yiyi didn't feel anything.

It's just that Chen Zhou's laughter is high.

But after three hilarious episodes, Yang Yiyi sensed that something was wrong.

She stabbed Chen Zhou with her hand, and found that Chen Zhou was thinking in a trance, but she didn't react.

After thinking about it, Yang Yiyi decided not to interrupt Chen Zhou's thinking first.

Wait a while, and then give Chen Zhou a good look.

Finally, at the end of the film screening, Chen Zhou returned to his senses.

When he stretched out his hand and was about to switch to the next movie, Yang Yiyi's hand followed.

Unsurprisingly, Chen Zhou's arm was heavy.

Chen Zhou reacted immediately and hurriedly begged for mercy: "I'm sorry Yiyi, I was wrong......"

Yang Yiyi asked, "What's wrong?"

Chen Zhou poured beans into a bamboo tube, and crackled and explained in detail what he had just been distracted by and thinking about Goldbach's conjecture.

Yang Yiyi suddenly pouted unhappily: "Your girlfriend is by your side, you don't want to, you actually go to Goldbach ......"

"Uh......" Chen Zhou touched Yang Yiyi's head and said softly, "Okay, I'll watch a movie with you now, and I don't want to think about Goldbach anymore, okay?"

Yang Yiyi shook her head: "Don't look at it, it's boring......"

Chen Zhou silently sighed in his heart.

After all, he said to watch a movie, but he was distracted and didn't take care of Yang Yiyi's emotions at all.

Chen Zhou estimated that when he was watching the movie, Yang Yiyi said something to himself, but he didn't react at all.

Then there is no choice but to coax well.

Chen Zhou began to grind hard bubbles, trying to coax Yang Yiyi.

In the end, it was the ice cream that worked.

After Chen Zhou agreed to contract the follow-up ice cream this year, Yang Yiyi smiled happily: "Then let's watch the movie and give you another chance." ”

Chen Zhou thought about this sleep aid, and wanted to refuse in his heart, but his body still agreed.

I can only try my best to make sure that I don't fall asleep!

Anyway, it's just been coaxed, can't you coax it again?

Yang Yiyi was actually not angry, she knew that Chen Zhou would be distracted when watching movies.

The first few times in the cinema, Chen Zhou didn't know how many times he walked through God.

But yes, in exchange for the ice cream for the follow-up of this year, it's still worth it.

As the plane flew above the clouds, Chen Zhou and Yang Yiyi followed the country of China on the west coastline of the Pacific Ocean to the country of rice on the east coastline of the Pacific Ocean.

Chen Zhou is actually not very interested in the country of rice.

But I have to say that the country of rice is very lucky.

Not to mention anything else, the transfer of the world's mathematical center can be said to be the luck of the United States.

Of course, this also needs the guarantee of strength.

And luck is only one type of strength.

At around 2 p.m., the plane landed on time at Boston's Logan International Airport.

It was the third time that Chen Zhou had passed through this airport.

For that landmark building, the special central control tower, he also saw it for the third time.

Pointing to the tower, Chen Zhou introduced Yang Yiyi.

Yang Yiyi took out her mobile phone, took a photo, and then sent it to Yang Xueyun to report her safety.

Yang Yiyi thought that her mother was asleep, after all, it was already two o'clock in the morning in Huaguo.

Unexpectedly, as soon as she sent the message, she received a reply from Yang Xueyun.

Yang Yiyi pursed her lips silently, edited the news, and told Yang Xueyun to go to bed early.

Chen Zhou naturally noticed Yang Yiyi's expression, and he silently pulled Yang Yiyi into his arms and let her lean on himself.

At the same time, Chen Zhou also reported safety to Chen Jianguo and Zhang Hongying.

Like Yang Xueyun, Chen Jianguo and Zhang Hongying also immediately replied to the message.

Chen Zhou can probably understand a little bit of what his mother is worried about.

After the shuttle bus came, Chen Zhou and Yang Yiyi took the shuttle bus to the terminal.

After completing the formalities, Chen Zhou looked around and saw the familiar sign.

According to Dean Sun's prior arrangement, the two senior brothers who were familiar with Chen Zhou and Yang Yiyi came to pick up Chen Zhou this time.

That is, when Chen Zhou came to MIT to attend an academic conference, he came to the airport to pick up his Harvard brothers, Liu Maosheng and Zeng Zigu.

Although they are students at Harvard, Harvard and MIT are neighbors after all.

It's close, and it's just right to pick up Chen Zhou.

Moreover, Chen Zhou and these two people are also familiar.

At the beginning, Dean Sun planned to arrange for students at MIT to pick up Chen Zhou.

But Chen Zhou thought about it, you didn't arrange it last time, isn't it okay this time?

chose these two brothers who got along well.

Pulling the luggage and taking Yang Yiyi, Chen Zhou came to Senior Brother Liu and Senior Brother Zeng.

Chen Zhou said with a smile: "I'm troublesome to the two senior brothers again." ”

Zeng Zigu also smiled and said: "Don't bother, I picked up your brand last time, and it just so happens that I can use it again this time." ”

When Chen Zhou heard this, he laughed.

Liu Maosheng also said at this time: "This is your girlfriend, right?

Chen Zhou nodded with a smile and introduced the two of them: "This is Yang Yiyi from the Department of Physics of Yan University, and of course, my girlfriend." ”

Then he introduced Yang Yiyi: "This is Senior Brother Liu Maosheng and Senior Brother Zeng Zigu, both of whom are students of the Department of Mathematics of Yan University, and they are also studying at Harvard. ”

Yang Yiyi said politely: "Senior brother, good." ”

Liu Maosheng and Zeng Zigu said together: "Hello junior sister." ”

After greeting each other, Liu Maosheng took Chen Zhou and them to pick up the car.

On the way to MIT, Liu Maosheng and Zeng Zigu began to educate Chen Zhou and Yang Yiyi about MIT's campus.

Although they are not MIT students, the good thing about being good neighbors is that they are familiar to everyone.

Harvard University and the Massachusetts Institute of Technology are both pearls on the banks of the Charles River in Massachusetts.

The close proximity of the two schools also promotes exchanges and cooperation between them.

In other words, MIT students, if they want to go to Harvard, they just want to enjoy the scenery of the Charles River along the way.

It's just that the first campus knowledge introduced by Liu Maosheng is the upcoming freshman ball.

In this regard, Chen Zhou was surprised: "There is also a freshman ball?"

When he first went to Yan University, Chen Zhou thought he could see the freshman ball.

Unexpectedly, Yanda did not.

It seems that we can see it now.

What Chen Zhou didn't notice was that Yang Yiyi on the side was looking at him strangely.

As if to say, you're a bit weird, right?
