When Lin Yu came downstairs, Jiang Feng, the head of the Secret Intelligence Bureau, had been waiting for him downstairs for a long time with a cold expression.

Because Lin Yu went to the United States, Jiang Feng, who was specifically responsible for Lin Yu's safety, went with him as a personal driver and bodyguard.

Although it seems that Jiang Feng is the only one to protect Lin Yu, in fact, there is a plainclothes team hidden secretly to deal with all emergencies.

As for Su Muxin's side, after the lessons of the last emergency, the Special Intelligence Bureau specially dispatched a team of female special agents to secretly hide beside Su Muxin to protect her.

It can be said that since the lesson learned last time, the Special Intelligence Bureau has done a very thoughtful and rigorous job on the safety of Lin Yu and Su Muxin, and it can basically completely eliminate the occurrence of emergencies.

Of course, if there is another emergency, it will be after all the agents have fallen...

After seeing Lin Yu come down with the suitcase, Jiang Feng also stepped forward, took the suitcase in his hand, and then put it in the trunk.

"Hehe, this trip to the United States will trouble Team Leader Jiang." After the two got into the car, Lin Yu looked at Jiang Feng in front of him with a smile and said.

"Where the duty lies."

Jiang Feng replied expressionlessly, and then drove towards the airport.

Looking at his face, which was paralyzed with no expression, Lin Yu also smiled helplessly, and immediately closed his eyes to recuperate, thinking about the things in his heart.

In the past two months, the two food compression technologies he designed before to supplement a large amount of energy have been completely formed, and more than 2,000 catties of finished products have been produced.

Among them, the number of solid highly concentrated nutritional capsules is the largest.

The newly developed capsules are not only very convenient to use, but also very time-saving.

Because the coagulated nutrient solution in it can be directly absorbed by the human body.

As we all know, the human body needs to eat eggs, milk, various meats, fruits and vegetables every day to replenish the energy and vitamins it needs.

When the human body digests, it takes several hours to break down the water, sugar, fat, protein, vitamins, minerals, inorganic salts and other nutrients contained in the food to replenish energy, and finally discharge a large number of residues.

From a scientific point of view, this kind of eating behavior is time-consuming and inefficient.

And this solid highly concentrated nutritional capsule can solve this problem perfectly.

Moreover, after taking it, it can ensure that the human body does not need to eat anything to replenish energy within 48 hours, and the effect is very strong.

However, although the effect of this capsule is very strong, there are some minor imperfections.

That is, it doesn't have any flavor, it's like a pill, it's purely for energy.

As for the new food compression technology, it is different, because it completely preserves the various flavors of the food.

For example, Lin Yu developed a special compressed jerky.

It looks similar to a small snack on the market, but the bite is like biting cowhide, chewy, and more laborious.

Of course, the effect of this kind of jerky is also similar to that of solid highly concentrated nutrition capsules, and only one piece can be eaten to maintain the daily needs of the human body for 48 hours.

Time passed slowly, an hour later.

Just as Lin Yu was thinking, Jiang Feng also drove to Hongqiao Airport in the magic capital.

At this time, not far from the airport, Chern Shiingshen and Qiu Chengtong were also chatting with Su Muxin and the others, waiting for Lin Yu's arrival.

"Why are you here, two old men, could it be that this IMO competition is led by your two elders personally?"

After getting out of the car, Lin Yu came to everyone with his suitcase, looked at the two old men in surprise, and said.

"Hehe, we happened to be invited by Deligne to attend the year-end report meeting in Princeton, so we led the team."

After the old man Chern explained, he looked at Lin Yu with a smile and asked curiously: "Lin Yu, what report are you going to do at this year-end report meeting, give us a thorough understanding, and our two old men will give you staff officers." ”

"Yes, let's talk about it, we can help you out."

Hearing this, Qiu Chengtong and the old man next to him also looked at Lin Yu with glowing eyes.

"Uh......"

Feeling the fiery gaze of the two old men, Lin Yu hesitated for a moment, and then said with a serious expression: "I said that I didn't have any preparation at all, do you believe it." ”

"Hehe, do you think we'll believe it?" Qiu Chengtong glanced at him, showed an expression of whether you believe it or not, and said with a smile.

Seeing this, Lin Yu was also a little helpless.

He really didn't have any preparations, why didn't anyone believe him all these years to tell the truth.

"Hmm...... You'll find out at the year-end report in Princeton. ”

After Lin Yu said a vague word to the two old men, he turned the topic to look at Su Muxin under their helpless gaze, and greeted them with a smile on his face.

There are a total of six junior high school students participating in the IMO this time, and basically all of them are from the magic capital and Kyoto.

When they saw Lin Yu greeting them warmly, except for Su Muxin, the other four people responded to Lin Yu very excitedly.

Especially the only boy, after seeing that Lin Yu was so approachable and didn't have any shelves, he hurriedly took out a notebook and pen from his backpack, and then looked at Lin Yu with a blank look and asked expectantly: "Emperor Yu, can you please help me sign a name?" ”

"Of course."

Looking at the name of Lu Tao on it, Lin Yu smiled slightly, took the pen and notebook, and wrote his name on the first page.

"***, Emperor Yu, your word is too good-looking!"

Looking at the vigorous and elegant, beautiful and sparse font on the notebook, like a dragon and snake flying, Lu Tao subconsciously burst into a foul language.

Hearing this, the four girls next to her, who were still a little shy, also hurriedly leaned over and took a look.

After discovering that Lin Yu's words were very chic and elegant, they exclaimed in surprise, but they also quickly came back to their senses, took out notebooks and pens from their backpacks with an excited face, and asked Lin Yu to sign for them.

As for everyone's requests, Lin Yu naturally agreed with a smile and signed for them one by one, causing everyone to cheer happily.

Seeing this scene, Su Muxin was quite proud in her heart, and at the same time, the corners of her mouth couldn't help but raise a smug smile.

After Lin Yu simply signed for everyone, the group also came to the waiting hall of Hongqiao Airport in the magic capital, and began to wait for the Eastern Airlines plane to fly to Princeton at 8 o'clock.

During this period, Lin Yu also chuckled, chatting with everyone calmly and casually.

The sunny and gentle temperament like a big brother next door also made everyone who was originally a little uncomfortable become open, and they discussed various issues with Lin Yu with great interest.

What makes everyone admire is that no matter what fields they come from and what kind of remote issues they raise, Lin Yu understands them very well, and will gently supplement and popularize science for them.

His wide range of knowledge, profound knowledge, and closeness and easy-going treatment also make everyone more full of love and admiration for him.

Such a warm scene naturally attracted other people in the departure hall.

Especially those netizens and fans who know Lin Yu, they are even more excited to take out their mobile phones to shoot videos and upload them to the Internet.

For a while, with their spread, Weibo and other major online platforms suddenly became lively.

"Hey! Brothers, look what I found, a wild U-emperor! ”

"I'll go, this seems to be the Hongqiao Airport in the magic capital, does anyone in the know know where the emperor is going to go?"

"Brother, you can't ask an answer like this, you should say that you are a big brother. (Dog's Head)"

"I guess Yuhuang should go to the United States, because looking at the costumes of these students, it seems that they are going to the United States to participate in the recent IMO competition, but I don't know if the Emperor is going to go there as a leading teacher, or if he happens to be passing by."

"What's that? IMO？ IMHO, I only know OMG if I haven't read a book. (Funny)"

"Hey, upstairs, you know OMG in English, but what about Japanese......

”

"This ...... If Yuhuang really wants to go to the United States, then won't we see the familiar husband and wife tonight?! ”

"It's over, Emperor Yu is gone, and the lord's youth is over."

………

With the discussion of countless netizens, soon, some insiders in the industry came out and explained the purpose of Lin Yu's trip to the United States, which is to be the leading teacher of this IMO competition.

Of course, there is no news about the Annals of Mathematics, whether it is in the mathematical community or on the Internet.

Even about Lin Yu's invitation to participate in the Princeton year-end report meeting, except for the two old men Chern, Shiingshen and Qiu Chengtong, and the two sisters Su Muyun, everyone in China did not know.

Just when all the netizens in China were discussing the news of Lin Yu's trip to the United States, the time also came to about eight o'clock.

A white Boeing plane finally descended slowly from the distant sky and arrived at Hongqiao Airport.

"Passengers please note that flight KGL747 from Modu to Princeton (PCT) has started boarding, please go to Gate 3 for boarding as soon as possible......

As the sweet voice of the flight attendant sounded, Lin Yu and the others also packed up their things and walked towards the boarding gate.

Because I used the public funds of the School of Mathematics to buy the air ticket, the group was all economy class, and they all happened to be in the same zone.

Half an hour later, everyone had boarded.

Since the straight-line distance from Huaxia to the United States is more than 88,000 kilometers, it takes more than ten hours to reach even from the magic capital to Princeton.

It just so happened that Lin Yu didn't sleep well last night, so after he got on the plane, he put on the eye mask that Su Muyun carefully prepared for him to sleep.

Coincidentally, Su Muxin was sitting next to him.

At this time, she was typing the code with the computer with relish, constantly modifying and perfecting her various auxiliary tools.

Just as Lin Yu closed his eyes and slept, a fierce quarrel suddenly came from the front.

"Mr. Wu, I'm sorry, our plane is already taxiing, and the mobile phone has to be modulated to airplane mode."

"I said that I will hang up immediately, what is urging! Or I'll call you sir, and you'll hang up the phone for me! ”

Hearing this fierce quarrel, Lin Yu frowned, and immediately took off his blindfold.

He happened to see a young man in a suit and sunglasses not far away, throwing his mobile phone heavily on the plate full of glasses in the flight attendant's hand, and then staring at her angrily.

And the young man's sudden move also caught the flight attendant off guard.

However, fortunately, she reacted quickly, and after the phone fell on the end plate, she quickly stabilized the end plate in her hand.

Otherwise, if she misses, all the glasses on it will have to be shattered.

After seeing this scene, a male flight attendant security officer not far away looked cold, and quickly got up and prepared to walk over to deal with it.

The passengers behind were also attracted by this sudden quarrel, and subconsciously looked at the past.

At the same time, just as the male flight attendant was about to stand up, a gentle and dignified female purser came over, pressed him back, and then went straight to the place of the incident and picked up the mobile phone on the end plate.

After finding that the other party had hung up the phone, the purser gave the flight attendant next to him a look and asked her to leave first for the time being.

She herself looked at the young man with a smile, handed over the mobile phone with both hands, and said softly: "Mr. Wu, the other party has hung up." ”

"Why, if I just say a few words, the plane won't be able to fly!" The young man in sunglasses looked at the purser angrily and said in a very angry voice.

"I'm sorry, the plane is about to take off, for everyone's safety, please turn it off."

The purser smiled gently, as if he was afraid that the young man would not understand, so he deliberately explained: "Because the frequency used by the mobile phone and the electromagnetic wave frequency of the aircraft and the tower are similar or even superimposed, it may be regarded as an operation signal sent by the tower, so that it causes misoperation, which is extremely dangerous." ”

Hearing this, looking at the purser's gentle appearance in such a soft voice, the anger in the young man's heart also calmed down a little.

"Then you let her stay away from me, I don't want to see her."

After calming down, the young man glanced at the flight attendant who was leaving not far away and said.

"Okay, I'll serve you the rest of the journey, and I'm the purser for this flight." The purser nodded softly and said.

"Okay, you serve me, right, come, look, now you're satisfied, right?"

Hearing this, the young man turned on the airplane mode on his mobile phone and took it out to show her for himself.

"Thank you very much for your cooperation."

After carefully observing the page on his phone and confirming that it was correct, the purser smiled and nodded, and then turned to leave.

Seeing that the contradiction was resolved, Lin Yu's originally slightly frowning brows also calmed down, he withdrew his gaze and continued to put on his blindfold to sleep.
