Chen Ya smiled and said:

"Lao Yang, I see that you treat me as a god, I haven't read a book on higher education for a day, and I have never applied for a job in the workplace, how do I know which major is good and which one is promising?"

Yang Changshuo tapped him with his finger and said:

"You see, this slippery guy is still hiding his secrets, this is a bad guy."

Chen Ya smiled but said nothing.

Yang Changshuo smiled and said to Mei Han:

"Little girl, you beg him, let him tell you how to choose, this kid has a copper head and an iron arm, but he can't stop the woman from asking, you ask for it to work."

Mei Han nodded after listening carefully, and turned her head to look at Chen Ya, but she hesitated.

If it is true, as the other party said, that he has not even studied in junior high school, then what's the point of asking him?

Mei Han looked at this boy who was not much younger than herself, and didn't know how to open her mouth for a while.

Chen Ya seemed to see her embarrassment, smiled, stroked the dial of the watch in his hand, and said:

"I'll give you two questions first, see how your basic skills are, how about it?"

Hearing that she could do the question, Mei Han became serious and nodded.

Fang Bai blinked.

The level of a person's questions can also show his own academic level.

She was a little curious about what kind of question the famous Bai Yujing would come up with.

As soon as Xia Zhijian heard that he was going to come up with a physics problem, he knew that it had nothing to do with him, and he was a little sad.

Yang Changshuo's eyebrows were lowered, and he couldn't see what he was thinking.

Chen Ya lay comfortably on the sofa and said:

"Let's assume that the sun is about to have a helium flash and will soon be destroyed, that the solar system will become uninhabitable, and that humanity must now start a ...... to save itself."

As soon as the first sentence came out, the expressions on everyone's faces became wonderful.

Especially Xia Zhijian, who was going to be in charge, immediately became energetic.

"Humanity's self-rescue plan, called 'The Wandering Earth', is to install an engine on the surface of the Earth to propel the Earth out of the solar system and towards Proxima Centauri 4.22 light-years from the Sun."

Let's try it soon, everyone. 】

"If you are the person in charge of the 'Wandering Earth' project, please make a plan."

When she first heard the question, Mei Han's expression was very strange.

But she endured. After all, some physics competition questions can have strange backgrounds.

It wasn't until she listened to the whole question that her face became completely stiff.

Fang Bai said loudly: "Mr. Bai Yujing, is your question really a physics question?" ”

She felt that this kind of topic was a bit embarrassing for Bai Yujing?

"That's physics." Chen Ya said with a smile, "You can use your mobile phone to search for known physical quantities, such as the mass of the earth, the distance from the sun, and so on. But the quantities that need to be calculated, such as the speed of the third universe, need to be calculated by your pen. ”

Fang Bai raised his eyebrows.

He was actually serious.

A helium flash is a short-lived thermal runaway phenomenon of nuclear fusion. As the hydrogen inside the star is depleted, the remaining helium is compressed into degenerate matter, which is characterized by the fact that the increase in temperature does not lead to an increase in the volume of the substance until the hot pressure becomes so high that it exceeds the degenerate pressure, resulting in helium fusion.

Helium fusion occurs inside the core of a star and dramatically increases the temperature of the core of Hengxin, which produces a very strong flash of helium fusion, which will release the equivalent of the entire galaxy at the same time in a matter of minutes.

When a helium flash occurs, the Earth's surface becomes uninhabitable.

The idea of using an "engine" to push the earth to "wander" in the universe is even more outrageous. What level of energy is needed for the Earth to reach escape velocity? How many years will it take to wander to Proxima Centauri?

This is only the background of the topic that Bai Yujing said.

Just describing this background requires a full physics education in the Poor High School. Bai Yujing's entire test of the topic is far more than that.

Mei Han was stunned for a minute.

Because this topic is too fanciful and too grandiose, I just think about it simply

A minute later, she suddenly realized that this question was not nonsensical.

The implicit condition of the "Wandering Earth" project is to preserve as much human fire as possible and "drive" the planet to its destination as quickly as possible.

And just now Bai Yujing told her that the basic physical quantities that can be searched are actually a hint, such as the circumference of the equator, the speed of the third universe and other data.

She gradually had a clue about how to make a plan.

Yang Changshuo silently took a thick pile of white paper from his desk, and put it in front of Mei Han along with a pen.

Mei Han didn't say a word and began to calculate on the white paper.

Chen Ya looked at the Patek Philippe watch with the Milky Way in his dial, and the hour hand had just passed two scales.

Xia Zhijian finally couldn't help it, and asked, "Mr. Bai Yujing, according to what you said, if you drive the earth away like a car, what should the people on the earth do?" ”

Chen Ya said: "Digging a dungeon underground, all human beings go underground to survive. ”

Xia Zhijian was stunned and said, "Isn't that the whole country, society, and even the international community all messed up?" ”

Chen Ya said: "Yes, this is actually a test of ethics, international politics, and social order, and perhaps, you can also try to formulate a plan to maintain a relatively stable order." ”

Xia Zhijian said in despair: "Mr. Bai Yujing, you are too difficult for me. ”

After speaking, he couldn't help but think in his mind what kind of structure should be adopted in order to maintain the order of human society in the face of the coming of the apocalypse.

…… Mei Han was lying on the coffee table, hot-headed, and her face was flushed.

The more she calculated, the more she realized how difficult the topic was.

She had used all her knowledge.

This question includes not only astronomy, but also mechanics, thermodynamics, electromagnetism, nuclear physics......

There was not a single data in the question, but after the initial plan was made, Mei Han's calculation formula had filled the entire manuscript paper.

Fang Bai pulled out a blank piece of paper and began to count on his own paper.

The more she thought about it, the more she found the topic interesting, and her hands were a little itchy, so she simply counted it herself.

She also whispered a few words with Principal Yang from time to time, but Mei Han was immersed in solving the problem and didn't notice it at all.

Chen Ya looked at his watch, and when the hour hand went just one scale, he said:

"Stop."

Mei Han woke up suddenly, only to find that she was sweating profusely, and her manuscript paper was also taken away by Chen Ya.

"Well, you're qualified."

"I've only calculated the basic plan," she said, swallowing a mouthful of saliva, "first using an engine to stop the Earth's rotation and revolution, and then letting the Earth reach escape velocity and fly out of the solar system." ”

"Before approaching its destination, it gradually decelerates, and then docks into the orbit of a new star, becoming a satellite of the new sun."

"After calculations, I found that it is very difficult to get an object as massive as Earth to escape velocity, so I plan to use the gravitational slingshots of other planets to accelerate Earth, such as Jupiter."

"This requires calculating Jupiter's Loch limit."

"But time was too tight, and I only calculated the amount of energy needed to stop the autobiography, and the time was over."

"It's already very good," Chen Ya said, "I didn't want you to finish this problem in the first place, the amount of work is too huge, and it's an impossible task." ”

Chen Ya continued: "The study of theoretical physics requires not only an amazing mind, but also a lifelong passion, and more importantly, a heart. You've calculated this point, and you've already passed the level. ”

"But if you didn't spend that minute thinking about the point of the topic at the beginning, the results would be a little better now."

After he finished speaking, Mei Han blushed.

Fang Bai also dropped his pen at this time, and sighed: "Impossible, this is an impossible task, it is impossible for the earth to successfully wander." Even if the Earth's surface were turned into a sea of fire, it would not be possible to push the Earth out of the solar system. ”

She turned to Principal Yang and asked, "Teacher, you must have known this result from the beginning, right?" ”

Yang Changshuo smiled but did not speak.

He went through it in his mind a little and worked out all the possible outcomes.

But some things aren't fun.

Chen Ya asked, "The second question, please listen to the question." ”

Mei Han was in full swing, holding the pen tightly in his hand.

"Do you want to put down roots in China in the future, or do you want to go to the United States?"

After hearing this question, Mei Han put down the pen.

There was some surprise.

This question has nothing to do with physics.

Mei Han glanced at Xia Zhijian and said:

"I—Of course I want to stay in my homeland."

"If your research can't be realized at home, will you choose to go abroad?" Chen Ya asked.

"Does this question make sense?"

Chen Ya leaned back on the sofa and said, "This is a very realistic thing. ”

Hearing his words, Yang Changshuo fell into a deep groan, and Xia Zhijian's face became not very good-looking.

"If your ambition is applied physics, then I would recommend you to transfer to another college, but your ambition is theoretical physics, and the scientific research environment in our country is not enough to support your dream when you graduate.

"Then one of my suggestions today may send a talent to Lao Mei. That's where I struggle. ”

After Mei Han heard this, she felt strange in her heart.

Originally, he was just asking about a professional matter, but it turned out that he seemed to have booked a ticket to a foreign country in advance after a few years.

Xia Zhijian frowned and said, "Mr. Bai Yujing, are you so pessimistic about our domestic scientific research environment?" ”

Chen Ya said slowly: "This is not pessimism, this is reality. ”

Yang Changshuo first frowned and thought for a while, and then raised his eyebrows and said, "Bai Yujing, you have something to say, I almost didn't hear it." ”

Chen Ya turned to him and smiled.

Fang Bai asked, "Teacher, what did you find?" ”

Yang Changshuo smiled and said to Chen Ya: "Just say it bluntly, you can't develop the corresponding scientific research environment in four years, what you expect is how many years you want?" ”

Chen Ya's hands and ten fingers were crossed together, and he made a "ten".

"Ten years." Chen Ya said, "In ten years, we will catch up and strive to be on an equal footing with Lao Mei and become a new global scientific research center." ”

Mei Han's eyes widened slightly.

Yang Changshuo smiled slyly: "The tone is not small, so what are you going to do?" ”

Chen Ya smiled slightly.

He knew that Lao Yang was taking the opportunity to get some information out of his mouth, but he didn't mind being tricked by him.

It's better to say that when he comes back to the capital this time, he doesn't blow some wind to the academic circle, and some people really don't have a sense of crisis.

"I have prepared three axes, and I can tell you the first axe at present," Chen Ya said, "Industry-university-research cooperation, first leave all those who do applied physics, and strive not to flow out." ”

Fang Bai said: "Isn't this what some domestic companies are promoting? For example, Beichen ......"

Halfway through her words, she suddenly realized something and her eyes widened slightly.

Although she didn't know what level Bai Yujing was in Beichen, she knew from some gossip that this person must be inextricably linked to Beichen.

Yang Changshuo said: "That requires a lot of money, you know, the funds are ......."

"To be honest, scientific research funding is too small compared to people's livelihood projects," Chen Ya smiled, "How much does a lunar exploration project cost?" 1 billion? 3 billion? This amount of money was spent by paving two roads and building a few shopping plazas. ”

"Not bad money?"

Chen Ya spread his hands: "It's not bad money." ”

Yang Changshuo leaned over and whispered: "Then on my side, there is a shortage of jobs, projects, and funds, how much do you think your first axe can digest?" ”

Chen Ya said: "As long as it is a high-quality talent and a high-quality project, you can digest as much as you have." ”

"Whatever the project?"

"No matter what the project." Chen Ya said, "Otherwise, do you really think that I came here to get your little tea?" ”

Yang Changshuo finally smiled, clapped his hands and said, "Okay!" Good! ”

Hearing the words of the two, Fang Bai guessed a little bit of the truth of the matter.

And Xia Zhijian and Mei Han, the two of them were still a little confused.

What deal did they make here, this is?

Yang Changshuo reached out and patted Chen Ya's shoulder and said:

"We have you in Huaguo, it's really a gift from heaven."

Chen Ya put the Pu'er just now on his lap: "I'll accept your words, but I have to take this bag of tea back." ”

Yang Changshuo's expression froze, and then he looked out of sight and out of mind, and waved his hand:

"Yes, yes, you can take it if you want, look at your face."

Chen Yale happily accepted the things, and the more Yang Changshuo thought about it, the more he lost, and said to Fang Bai:

"While Bai Yujing is still here, if there is anything else you want to ask, ask him as well, and come out with more words, otherwise my flesh will hurt!"

Fang Bai knew that the teacher was letting himself assist, rolled his eyes, and asked:

"Uncle Bai Yujing, I would like to ask you, Beichen will soon launch the first commercial nuclear fusion power station, what impact will this have on the future Sino-American confrontation situation? How did you predict that? ”

"I don't predict, I just change." Chen Ya said, "It just so happens that the academic circles, the military circles, and the future of the motherland are sitting here, so I can reveal to you a little bit about the direction I want to change......

……

After coming out of Principal Yang's "Hidden House Building", Mei Han still feels amazing.

Originally, I just came to ask the principal to change majors, thinking it would be a personal exchange.

But what I didn't expect was that I seemed to have experienced a very wonderful conversation.

Recalling Bai Yujing's words, she still feels a little incredible.

That person seems to be a combination of a madman and a genius, and every word he says makes people feel unbelievable, and at the same time feels a little bit of truth.

He gave Mei Han the feeling that he was like a business elite such as Musk and Zuckerberg, every sentence was loud, but it sounded like science fiction.

Xia Zhijian and Fang Bai took Mei Han and walked on the way out of the courtyard.

The two did not speak for a long time.

After walking like this for more than two hundred meters, Xia Zhijian spoke:

"The content of today's conversation is not allowed to be leaked anywhere."

Mei Han looked at the uncle.

She knew it was to herself.

His expression was very serious, so serious that he even had a bit of a thick murderous aura, which was an iron-blooded temperament that could only be condensed on the battlefield.

Mei Han's throat was dry, and she nodded again and again.

"Today's conversation at the principal's house may continue to have an impact on reality in the next ten years." Fang Bai said, "Holding the sword, if it is really as he said, are you mentally ready to change?" ”

Xia Zhijian said: "As a soldier, you should carry out your orders, even if you can't accept it psychologically, and you are emotionally afraid of difficulties and dangers, you should not hesitate to come forward." This is the duty of a military man. ”

He turned to Fang Bai and smiled gently: "What's more, judging from his description, our future is not so dangerous. ”

"Zhijian, do you believe his words?"

Xia Zhijian nodded: "He has a temperament, this kind of temperament, I have only seen it in the leader." I believe in him. Perhaps, he was a natural leader. ”

Fang Bai shook his hand and said leisurely: "This 'hidden talk' may become an important historical scene in the future. ”

Mei Han looked at Fang Bai in disbelief.

"Didi—"

The horn sounded from behind them, and the three of them saw that Bai Yujing, who was talking in the hidden house just now, was riding an electric car, passing them crookedly from behind.

"See you later!" He held out his hand to greet them.

Fang Bai said loudly: "You're Principal Yang's car, right?" ”

Chen Ya stopped the car, turned around and said, "Yes." I borrowed it from him. ”

"The rules of Beijing University are very big, electric cars are not allowed to enter the campus, only Lao Yang's electric car can enter and exit, so I borrowed his car, this should be unimpeded, right?"

"Ah......h

Under the strange looks of Fang Bai and the others, Chen Ya got back into the car and rode into the distance.

"Ride my beloved bike......"

……

The winter vacation is approaching, the final exams have passed, and most of the remaining club activities are actually gathered in the name of group activities.

Lu Qianzi has been in the activity classroom for half an hour, and all the time has been spent discussing with friends how to spend the winter vacation, and she almost forgot what club she was mixed in.

While she was chatting happily, Zhao Anqi pretended to cough twice and sat next to Lu Qianzi.

Zhao Anqi was wearing a long dress by Parada, and she looked very well-dressed. She has a lot of fans at school, because she is also a "celebrity" in the circle.

She has a good family condition, and she is especially good at setting up her own marketing persona, and she has a good relationship with some children of the family, so her value has also risen.

But Lu Qianzi doesn't like this person very much.

"Akane, when you came, I saw that you were carrying a Patek Philippe bag in your hand, did you just buy a watch?"

As soon as Zhao Anqi opened her mouth, it was a sensitive issue.

Chen Ya "rented" two watches before, one for three million, one for seven million, and the one for seven million was thrown to himself, but he forgot to return it to him, so he had to keep it in his hand.

Lu Qianzi said: "I didn't buy it, it's my family's, and I'll keep it for him." ”

"Your dad's?" Zhao Anqi arched her with his arm, "Take it out and take a look." ”

The girl who was chatting with Lu Qianzi next to her also became interested and asked, "What Patek Philippe watch?" ”

Lu Qianzi shook her head, and said with a reluctant smile: "No, no, it's too precious, I can't afford to take responsibility if I see it bad." ”

Zhao Anqi's mouth was deflated and said:

"Qianzi, what you said is a bit mean, are all classmates all old hats of the countrymen, can you still see it bad when you look at your watch?"

She said this loudly, and the eyes of the other students in the club also turned to this side.

Lu Qianzi couldn't cope with this person, and said:

"I didn't mean that, the main thing is that this watch is really valuable, and it's not my ......"

Zhao Anqi was even more unhappy when she heard this, and said with a dark face:

"Knowing that you are expensive, you don't have to repeat it. I don't like us to say it directly. ”

A boy sitting not far away came up and said:

"Zhao Anqi, what you said is wrong, what kind of person is Qianzi, everyone knows, how can she look down on people casually, she must have her reasons for not showing it. Isn't it? ”

The boy's name was Zha Xiaoming, and he spoke like a loud bell, and everyone in the classroom heard it.

Lu Qianzi rubbed her forehead, feeling that her head hurt even more.

Cha Xiaoming was her classmate, and the whole club knew that he had a "crush" on her. Some members of the club also gave him assists, intentionally or unintentionally.

Although Lu Qianzi knew that he was talking for her, it was better not to say it.

When some students heard a few words, their expressions when they looked at Lu Qianzi were also a little sour.

The conditions of Lu Qianzi's family are the best among them, so she has always been careful not to deliberately show off her wealth, and Zhao Anqi found this opportunity to accuse her of looking down on people and belonging to moral kidnapping.

"Alright, alright." Lu Qianzi took out the gift box from the drawer and said, "Lest someone say that I look down on people with dog eyes, just show you." ”

When the gift box is opened, the precise transparent dial of Patek Philippe P4105 is revealed.

When many people saw it, they all let out a "wow" sound.

This watch is not understated at all, and you can see how luxurious it is from the body.

Zhao Anqi picked up this watch, put it in front of her eyes and looked at it carefully, the more she looked at it, the more fascinated she became, pushed Lu Qianzi, and said:

"Akane, how much does this watch cost?"

Lu Qianzi didn't want to answer, so she said coyly: "It's very expensive anyway." ”

Zhao Anqi glanced at her, "tsk", and said:

"Isn't it just a watch?"

The reason why she spoke with a gun and a stick was also related to Zha Xiaoming.

Zhao Anqi pursued Cha Xiaoming before, but was rejected.

Although she was rejected, the two still made an appointment to be friends, and Zha Xiaoming treated her as a female girlfriend, but due to the well-known relationship, the relationship between Zhao Anqi and Lu Qianzi became very awkward.

So she has always liked to compete actively with Lu Qianzi.

She stretched out her hand to Cha Xiaoming and said, "Come here." ”

Zha Xiaoming sat down in front of them and asked, "What's wrong?" ”

"Hand out."

"What for?"

"Tell you to stretch out, and I'll stretch it out." Zhao Anqi is a queen.

Zha Xiaoming had to stretch out his hand, Zhao Anqi put the watch on his wrist and compared, his eyes lit up, and said:

"Zha Xiaoming, you are quite suitable for wearing a famous watch!"
