Metropolis: 1 billion rewards for public welfare

The other party introduced: "Hello, I'm Liu Ye, an intern researcher of Dragon Academy of Sciences, you can call me Xiao Ye."

Ye Xiu didn't answer and asked instead: "Intern researcher? May I take the liberty to ask, what is your degree?"

Liu Ye smiled and said, "Ph.D. degree in Micro Quantum and Mechanics."

Ye Xiu: emmmmm

Is this the legendary ultimate powerhouse, the strongest academic master?

Microquantum and mechanics...etc.

Undecided... Quantum Mechanics?

Ye Xiu clicked his tongue and called out in his heart what a guy~

After chatting with Liu Ye for a few words, he entered the Academy of Dragon Sciences with him.

Chapter 618 Mr. Ye, are you interested in... coming to Dragon Academy of Sciences to work?

Dragon Academy of Sciences, established in November 1949, is the highest academic institution of natural science in China, the highest consulting institution of science and technology, and the comprehensive research and development center of natural science and high technology.

The entire Academy of Dragon Sciences covers an area of ​​thousands of acres, according to the official website of the Huaxia Academy of Sciences in November 2018.

The hospital has a total of 12 branches!

More than 100 research institutes!

3 universities!

More than 130 national key laboratories and engineering centers!

More than 210 field observation stations!

Undertake the construction and operation of more than 20 national major scientific and technological infrastructures.

There are more than 7.1 formal employees.

More than 6.4 graduate students~

It is such a huge group that has researched a series of the world's top and most advanced scientific and technological achievements.

Looking at the research institutes in front of him now, Ye Xiu admired these people from the bottom of his heart.

To be able to study assiduously for ten years is really not something that ordinary people can do.

Along the way, Ye Xiu saw all kinds of strange laboratories and research institutes.

Liu Ye led the way and acted as a tour guide for Ye Xiu, introducing him.

"This is the Institute of Isotope Geochemistry."

"This is the Cryosphere Science Institute..."

"This is the Loess and Fourth Institute of Geology..."

"This is high-performance ceramics and ultra-microstructures..."

"this is……"

Regarding the names and research directions of these research institutes, Liu Ye said clearly and logically.

Ye Xiu nodded along on the surface.

I couldn't help applauding myself: It's so wonderful~ I haven't heard any of them~~

Is this the real world of academic masters~~

Ye Xiu once thought he was a top student, but he didn't know that he was a rookie until he met Liu Ye~

Not to mention a top student, not even a scumbag.

In this Dragon Science Academy, I am afraid that even a sweeping degree can hang him~~

After following Liu Ye for nearly 5 minutes, the two came to the door of a research room.

Liu Ye stepped forward, knocked on the door, and shouted, "Mr. Li, Mr. Ye is here."

Soon, the door was opened.

A man in his 50s or [-]s wearing a numbered musical notation came out quickly, and shook hands with Ye Xiu with a smile: "Oh, you are Mr. Ye. You are far more famous than you meet. You are younger than the rumors."

Ye Xiu smiled: "Mr. Li was joking, I'm already 24."

"Oh, I'm 24, you're not too young when you say that."

Mr. Li immediately took the words, smiled and said: "It's time to talk about marriage, let me show you this girl, do you like it? If you like it, I will introduce it to you!"

No matchmaker fee! "

While talking, Old Li smiled and handed Ye Xiu a photo.

Ye Xiu:? ? ?

Good guy, you tricked me as soon as we met~

Ye Xiu casually glanced at the photo. The girl in the photo was white and tender, but her face shape was at least five points similar to that of Mr. Li.

Ye Xiu laughed and said, "Elder Li doesn't need to care about this, I have a girlfriend."

"Oh, is that so, that senior from Huaqing University?" Mr. Li obviously knew about the incident of Huaqing University's sloppy hands.

At that time, the Academy of Dragon Sciences stood up and spoke for Ye Xiu.

Mr. Li added: "To be honest, that girl looks good, but her education is too poor. My daughter is a Ph.D. from the University of Science and Technology of China! She will also enter the research institute in the future!"

Speaking of his daughter, Mr. Li was full of pride.

Ye Xiu clicked his tongue in his heart: It really is a tiger father without a son, my father is in the Dragon Science Academy, and my daughter is also in the Dragon Science Academy.

Really strong outrageous~

Unfortunately, Ye Xiu didn't care about this.

Who you like is mainly based on the feeling, if the feeling is right, then it is right.

It has nothing to do with academic appearance.

"Okay, Mr. Li, if you don't talk about business, then I will leave."

Ye Xiu said excitedly.

"Just kidding, don't take it seriously.

Come, come, you come in first. "

Afterwards, Mr. Li brought Ye Xiu and Liu Ye into the laboratory,

As soon as he entered the laboratory, Ye Xiu saw a huge mechanical arm,

It was an essential piece of machinery for building a car, but it seemed to be only half built, not quite finished.

"Is it a problem with the robot?" Ye Xiu asked proactively.

Mr. Li nodded, and then took out a piece of paper, on which a lot of derivation formulas were densely written.

"I calculated it strictly according to the design drawings you gave, but I couldn't calculate the result you gave.

You see, the main thing is here.

Ashamed to say, the derivation formula on your design drawings... I can't deduce it. "

Ye Xiu took the design blueprint and the step calculation paper, looked at one side carefully, and frowned.

He smiled and said, "Oh, that's the problem.

You can't use your formula here, you have to use this.

You look at it.

"

It's easy to say, but when it came to writing, Ye Xiu filled a 4K paper, and his hands were a little sore before he stopped.

Handed it to Mr. Li, smiled and said, "It should be calculated like this here, take a look, is this correct?"

Mr. Li took it over, looked at it carefully, and his face was filled with joy.

Nodding again and again: "So that's the case, it turns out that the direction I deduced has been wrong all along, no wonder no wonder..."

Resisting the excitement in his heart, Mr. Li looked at Ye Xiu again, his eyes glowed, and Ye Xiu's back shone a little.

Mr. Li said with a smile: "Mr. Ye, are you interested in... coming to Dragon Academy of Sciences to work?

Guaranteed not to treat you badly! "

Even Ye Xiu knows how to derive formulas that he doesn't know, what a genius!

If you stay in Longke Academy, you will be a rising star!

Elder Li admired Ye Xiu very much.

pity……

Ye Xiuzhi is not here.

Directly declined.

Mr. Li's face was full of regret, and he still didn't forget [Treatment]: "Ye Xiu, don't you really think about it? You're going to miss out on an opportunity to become famous all over the world with an annual salary of one million~~"

Ye Xiu thought to himself: To be honest, an annual salary of one million...is a bit small~~~

As for being famous all over the world... isn't it a matter of time?

"I'm sorry, I really didn't intend to do that." Ye Xiu continued to refuse.

"Hey, that's fine." Mr. Li was full of regret.

Liu Ye on the side suddenly said, "Mr. Li, the International Academic Exchange Conference is about to begin."

"Oh yes!" Mr. Li slapped his head, "I almost forgot if you didn't tell me."

After finishing speaking, seeing Liu Ye's expression was not quite right, Mr. Li thought of something and asked, "Is that guy Ruiz here too?"

Liu Ye nodded: "Yes, Mr. Li, why don't we go."

Ruiz, a researcher at the Academy of Power Machinery Science at Saber University Research Institute.

There is strength, but people are arrogant and look down on Huaxia people.

For this reason, Mr. Li often quarreled with him.

Unexpectedly, he came again this time.

Mr. Li thought for a while: "Why not? Wouldn't that make them look down on me, Dragon Science Academy, and Huaxia?"

After speaking, he grabbed Ye Xiu and walked out: "Come on, I'll take you to meet those crooked nut researchers!"

After finishing speaking, the three of them walked towards the academic exchange hall in the east together.
