Regarding Zhao Yu's arrangements for his own safety work, Lin Yu is not clear.

At this time, he was busy writing the relevant technical requirements for the neuronal chip on the computer.

was busy until the evening, and after Lin Yu simply had dinner with everyone, he returned to the room again, drawing equipment drawings and compiling knowledge bases.

The time was spent in Lin Yu's attentive and serious work.

While Lin Yu was concentrating on work, domestic netizens who were in the daytime were happily cheering on various platforms.

As for the reason for their cheers, it was because of two videos that exploded on the oil pipes of the United States.

[Shocking! Baiji's new anti-cancer drug "Bai Ze" inhibitor is finally sold abroad! 】

[Shocked! Huaxia people only need to spend 100 yuan to buy "Bai Ze" inhibitors with their ID cards! 】

This shocking title made countless netizens in China see at a glance that this was a video posted by Chinese compatriots abroad.

Especially when netizens watched the whole video and knew the expensive price of Bai Ze inhibitors abroad, as well as the expressions of envy, jealousy and hatred that made foreigners show envy, jealousy and hatred because of the exclusive price of Chinese people, they laughed out loud of pigs.

"Hahaha, I'm laughing to death, Bai Ze inhibitors, which we only sell for 100 yuan in China, are sold abroad for 2,999 dollars, brothers, this price is simply amazing."

"Ahem, I don't know why, looking at the resentful eyes of foreigners, I am inexplicably happy (bad laugh)"

"Good guy, a bottle of Bai Ze inhibitor abroad costs 3,000 US dollars, if this is converted into RMB, it will be more than 20,000!"

"! Foreign countries actually want more than 20,000 bottles of Bai Ze inhibitors?! ”

"Shhh...... Brothers, I suddenly had a bold idea! ”

"Punishment, friend, you haven't passed away when you're idle, and you want to do some criminal violations? Let me see the torture point, it's a bit of a thought, the idea is solid, this is going to be recorded in the book of death, your little day is getting more and more judgmental, this kind of prison can not be imprisoned in front of the new body. ”

"Hahaha, it's really a talent upstairs."

"Damn, it used to be our cancer patients begging to buy foreign anti-cancer drugs, but now it's finally the other way around, it's so fucking cool!"

"I'll go, the Chinese people abroad can also buy Bai Ze inhibitors for a hundred yuan, wow, brothers, I love the heart-warming operation of this wave of details of Baiji Company directly."

"With all due respect, as far as Baiji Company is a patriotic and conscientious enterprise, if it is not popular, everyone here is responsible. (Dog's Head)"

………

Since it was around seven o'clock in the evening here at Princeton, it was just the time when the Internet was most active after eating, swiping on the phone.

As one of the world's largest video-sharing websites, YouTube naturally has a huge number of users.

Therefore, when the videos on these two YouTube pipes continued to ferment with the passage of time, they immediately became the first on the YouTube hot search list.

For a while, not only domestic netizens were discussing enthusiastically, but even Chinese compatriots around the world were also moved to tears, and a deep sense of pride emerged from the depths of their hearts.

"As a Chinese person who has been traveling abroad for more than ten years for a living, this is the first time I have personally felt the heart-warming move from our distant motherland.

"I don't know why, when I took the Bai Ze inhibitor from the hands of my smiling compatriots, my tears suddenly fell uncontrollably."

"I want to see if the pear trees planted by my grandmother are bearing fruit, I want to eat pears..."

"I can only say that I am very proud and proud to be born as a Chinese, thank you for the heart-warming act of Baiji Company, and also thank the motherland, and wish our motherland eternal prosperity!"

"I don't regret entering China in this life, and I will be a Chinese person in the next life!"

………

For all the Chinese compatriots outside, tonight is destined to be a night that cannot sleep.

Because the homesickness buried in their hearts was stimulated by the price of Bai Ze inhibitors, and they broke out in an instant, and they couldn't stop it at all.

Especially now that it is still the end of December, the New Year's Day and the Spring Festival that are approaching China, it makes many people who are wandering outside cry.

As a result, some homesick people can't resist buying plane tickets overnight and getting ready to go home.

However, most of the Chinese compatriots abroad still forcibly stopped the urge to go home.

Because they have no one behind them, they can only rely on themselves to work hard to earn money alone in a foreign land.

And their purpose is to make a better life for their families far away from home.

………

Lin Yu didn't know about the various hot topics caused by Bai Ze inhibitors at home and abroad.

Because when he focuses on his work, all information from the outside world is in a state of shielding.

In this state of eating, sleeping, and working every day, two days are fleeting.

In the past two days, the leaders and vice-teams of IMO competitions from other countries around the world have also rushed to the Princeton Hotel.

And Su Muxin and the others also began to prepare for the IMO competition, and they all worked hard to review in the room, without taking a step out of the room.

In the early morning, the bright sunlight shines through the glass and shines on the shiny floor, and the warm light instantly fills the entire bedroom.

Lin Yu sat on the chair, staring intently at the documents that were about to be completed on the computer, and his slender ten fingers were rapidly tapping on the keyboard, making a crisp collision sound, like a spirit jumping on his fingertips, light and graceful.

"Whew, it's finally done."

After a while, the crisp collision sound on the keyboard suddenly stopped, Lin Yu pressed the enter key heavily, and then breathed a long sigh of relief, and the whole person slowly relaxed.

After two days, he finally sorted out the drawings of the relevant mechanical equipment needed for the neuronal chip, the detailed materials in all aspects and the attention of the basic knowledge, and completed the writing.

As for the remaining theoretical knowledge and technology related to the complete industrial system, it will take several days to complete it.

However, Lin Yu should have returned to China at that time, and the specific requirements can be discussed with Zhao Yu in detail.

Just as Lin Yu was relaxing, the mobile phone on the table suddenly rang.

After picking it up and taking a look, Lin Yu found that it was a strange call, and it was from Princeton.

Lin Yu raised his eyebrows, and immediately connected the phone.

In the next second, a pure English voice came from the other end of the phone.

"Mrlin, I'm sorry to bother you, I'm a staff member of Princeton University, and I'm calling you mainly to remind you that around ten o'clock this morning, we will hold a meeting on the IMO competition in 3 Teaching 101, please pay attention to the time and don't be late."

"yes, okay, I got it." Lin Yu responded lightly, and also replied in English.

And after getting Lin Yu's reply, the other party also politely said a few words of thanks to Lin Yu, and hung up the phone.

Looking at the time, Lin Yu found that it was only half past eight, so after he sent the files on the computer to Zhao Yu, he went out unhurriedly and walked towards the rooms of the two old men.

Half an hour later, under the expressionless follow-up of Jiang Feng, the four of them walked together and came to Princeton University together.

Because it was still early, Lin Yu and the others walked around Princeton University.

It is worth mentioning that because they have participated in many year-end reports of Princeton University, the two old men naturally became Lin Yu's tour guides.

As one of the world's top universities, Princeton University has a beautiful environment, and walking around the campus is like walking in a small 19th-century town.

The well-preserved old Gothic architecture, the elegant campus environment, and the turquoise waters of Carnegie Lake are all very pleasant.

Even the decoration of the teaching building and dormitory building has a kind of Hogwarts School of Witchcraft and Wizardry style, which is very dreamy.

The time came to about half past nine, and under the leadership of the two old men, Lin Yu came to the most famous Princeton Corridor at Princeton University.

The Princeton Promenade, a road that runs through the entire Princeton University, is also the place to go to the teaching area.

The road is lined with green grass and trees, and the clear river flows quietly around the school, which is quiet and serene.

Sitting on the lawn in front of the university concert hall, it is as if you can hear melodious singing.

Walking along the depths of the corridor, a strong academic atmosphere came to the face, and the lively discussions were endless.

Mathematicians from all over the world, as well as students from other top universities, present their latest theories on blackboards on both sides of the corridor.

A variety of ideas and perspectives collide here, and brilliant sparks bloom.

There are ideas that are being born, and there are also opinions that are constantly being denied.

It is a sacred place for all mathematicians in the world, because tolerant Princeton has given all of them a stage to speak freely.

"Well, it's not bad here."

Looking at the lively scene and the strong academic atmosphere in front of him, the old man Chern turned his head and said to Lin Yu with a smile.

"Well, it's really good, whether it's the academic atmosphere, the environment, or the teaching resources, it's the world's top." Lin Yu nodded and said approvingly.

One thing to say, Princeton's academic atmosphere, which speaks freely, equally, and without any racial discrimination, is already worthy of the attention of many mathematicians and gifted students.

Not to mention that there are many of the world's top mathematicians, who teach and mentor on a daily basis.

Therefore, it is not for nothing that Princeton University is recognized as a mecca for mathematicians.

"Hehe, go straight ahead to the third floor of the building where we are going to have a meeting, you can just go over later, and we will also go shopping."

After saying a word to Lin Yu with a smile, the old man Chern walked skillfully towards the corridor with Qiu Chengtong next to him.

In this Princeton promenade, where math bigwigs are gathered, it would be a waste of time not to discuss with those mathematicians, but to walk with acquaintances.

Seeing this, Lin Yu also shrugged his shoulders, and immediately followed Jiang Feng behind him like a shadow, and walked around casually.

I have to say that there are still many hidden math bigwigs in the Princeton Promenade.

This point can be seen by Lin Yu from the blackboard next to the corridor, and the world's mathematical problems that have been proved one by one.

Goldbach's conjecture, Riemann's conjecture, NP complete problem, Hodge's conjecture......

To put it bluntly, the world's seven millennial problems are all on these blackboards, and there are many annotations and various ideas and explanations made on them.

But it's a pity that almost no one looks at these math problems with an exploding degree of difficulty except for the math boss himself who stands in front of the blackboard.

No way, this kind of world-wide mathematical problem is too profound for ordinary mathematicians and students to understand.

Soon, Lin Yu came to the blackboard of the Riemann conjecture that he was most familiar with.

He looked at the gray-haired professor who was writing his theory intently, and then at the verification process on the blackboard.

What surprised Lin Yu was that this person actually used his weakened version of the Riemann conjecture to prove the dimensionless constant of quantum mechanics.

However, one thing that is different is that this person does not demonstrate the Riemann hypothesis in the field of complex numbers, but verifies it on the entire Riemann function.

In this regard, Lin Yu could only smile slightly, and then turned around and left.

He knew very well that it would not work to test the entire Riemann hypothesis by his own methods in the field of plural numbers.

Because his verification method in the field of complex numbers is separated from the complete Riemann conjecture proof, how can it be successfully reversed.

Lin Yu walked around, his gaze constantly sweeping over the blackboard around him.

The verification process of the various mathematical problems above is good and bad, but there is no shortage of bright ones among them.

For example, the old professor in front of him who wears glasses and looks courteous looks like the Mediterranean Sea.

The "test of the 51st Mersenne prime" he showed made Lin Yu's eyes shine.

"In the prime factorization of the Merson number (≥ m2), there must be at least one prime factor congruent with 3 (mod4)."

"A fundamental theorem about the Merson number states that if MP is prime, then the exponent p must also be prime, which stems from the equation:

2ab-1=(2a-1). (1 +2a+22a+ 23a…+2b-1)a=(2b-1). (1 +2b+22b+ 23b…+（2a-1)b。

Test 1: The prime nature of Merson numbers with composite exponents is excluded, e.g., m4 = 24 1 = 15 = 3 × 5 = (22 1) × (1 + 22).

Test 2: ......

Lin Yu stopped and began to carefully observe the equation and the theorem he verified in each line.

For now, though, the report looks logical and logical, with few errors.

Mersenne primes have always been a hot topic in mathematics, attracting countless mathematicians to test them one after another.

According to the information that Lin Yu knows, in this parallel world, all mathematicians in the world have found a total of 50 Mersenne primes.

But the math boss in front of him is using his pen to calculate the 51st Mersenne prime.

It can be said that this person is either a madman or a peerless genius, because it is very difficult to calculate the 51st Mersenne prime with a pen, so difficult that it can basically be said to be impossible to complete.

Because the amount of calculation is too large, so large that it can only be checked by a computer, and it is impossible to succeed without superb problem-solving skills, tenacious perseverance, and huge computing power without manual hard calculation.

However, this is not a big problem for Lin Yu, who has a rich knowledge base and superbrain skills.
