()   Floating island, square.

After completing a "century" speech, Chen Yu felt extremely comfortable and sobered up. He waved his hand: "Send the papers and start the exam!"

"yes!"

Dozens of professors nodded excitedly, trotted into the square, and stood on the marble platform in the front in order.

"Students." Chen Yu put down his hand and directed: "I have noticed the number on the ground beneath my feet long ago? There are also your numbers in the invitation letter. Please stand in their respective positions according to the number and start preparing for the exam."

With Chen Yu's motivation just now, the students were still in a buff state and were very efficient. After only two minutes of scattering, they all found their respective positions.

As the saying goes, a high position is heavy.

The same sentence means different effects in different people.

As the most "power" and "status" special figure in the world, Chen Yu must have profound thoughts no matter how he interprets his words.

Don't ask, there is no other reason. This is the setting engraved in the human cultural genes, which began in the ancient Greek era.

Waiting for the students to stand in line, the professors began to distribute the test papers, cardboard, straw paper and oil pens. They sent them from the first column to the last column.

Depending on the fields of expertise of these young academic masters, each row of the test papers is also different. The only thing that is the difficulty beyond imagination.

Taking off the armor of his hand, Chen Yu raised his wrist and looked at the time, and said aloud: "It's normal that there are still ten minutes to start the exam, but efficiency is the most important thing. Since everyone comes early, start it directly."

The students stood there, holding the test papers and looking at each other, at a loss.

"What are you looking at?" Chen Yu frowned: "Answer the question."

"I...we answered standing?"

"I haven't experienced it before? I've met me long ago, I've experienced it long ago." Chen Yu nodded: "I just want to: strip away your natural pride and eliminate those external interference. Assume that you are all top academic masters and have strong stability. In such a purely standing environment, you can see whether you are still a good student."

Everyone: "..."

"That's right. We have to expose your hardware, see through your software, and restore the t1 book... No, it is to restore the essence of the written test." Chen Yu waved his hand: "The scientific research journey is difficult and boring, and it is also to allow you to adapt in advance, so don't be delayed."

"I see."

Most students suddenly realized and began to answer questions seriously without hesitation.

Dozens of professors crossed the aisles, monitoring students to prevent cheating.

"Bang!"

He raised his hand and pointed his fingers. The gray particles suddenly turned into chairs and appeared in the square. Chen Yu shook his robe, sat down leisurely, and hooked his hands in front: "Professor Li, come here."

"Principal." Professor Li hurried over and said, "What are you asking?"

"Are there any remaining papers? Let me take a look."

"You want to do it too?" Professor Li's eyes lit up.

"Well, see how good you big professors are at the questions."

"well!"

Professor Li seemed a little excited and immediately took out a few test papers from his casual pocket and handed them to Chen Yu: "Principal, these are all the same papers, and these are the questions that the students do."

"Yes." Chen Yu nodded and took it, turning on the first math paper.

He believes that he is also a high school student. After turning over by the salted fish, he can even cut the top ten in the sixth ranks and college, and he deserves the reputation of being a top student.

Since they are all academic masters, even if they have a lower value, it is okay to pass the exam?

Thinking of this, he picked up his pen decisively and read the first major question carefully.

Suppose r is a set of real numbers of the body, find all functions f:r(right arrow)r, so that for any real numbers x and y there are f(f(x)f(y))+f(x+y)=f(xy)

Chen Yu: “…”

After pushing the mask, he moved to the second question with a calm expression.

There are 1987 beads on the circumference. Each bead is dyed twice, red twice, blue twice, or red once, and blue once. Finally, it is counted that 1987 dyes are dyed red and 1987 dyed blue. It is proved that at least one bead has been dyed red and blue two colors.

Chen Yu: “…”

Looking up, he looked at Professor Li, who was concentrating.

"How is it? Is the difficulty a little simple?" Professor Li scratched his face and was embarrassed: "There are too difficult math problems in front of us, and we are afraid that the students will not be able to solve them. If you are not satisfied, look at the difficulties in the back."

Is this a question from a psychopath?!

Chen Yu opened his mouth, held the words "Fake" in his throat and didn't say it, and continued to look at the third question of "simple".

A primitive point is an ordered integer pair (x,y), where is the greatest common divisor of x and y?

The third question is very short, but the difficulty is...

After silently closing the paper, Chen Yu shook his head and handed the paper and pen to Professor Li.

"School... Principal, these... these puffs..."

"You're laughing?"

"No! I choked!" Professor Li shook his head repeatedly: "I... I just want to ask, are you not satisfied with these questions?"

"Satisfied." Chen Yu looked at the students who had written a lot and forced a smile: "I am very satisfied. I hope you can always maintain such excellent results."

"But...but..."

"Go down and let me be quiet."

"Okay." Professor Li held the paper with a serious face, muttering while looking at it: "Oh, it seems to be too simple."

Chen Yu: “…”

With his head raised, Chen Yu looked at the sky with a expressionless face, closed his eyes, and asked himself a question in his heart.

If there is no super-time and space promotion, is he coming to Earth just to make up the numbers...

"I originally thought the question would be difficult, but I didn't expect it to be so simple." A female student standing in the front row whispered to herself, turning the next page of the test paper.

“…”

Chen Yu silently covered his chest that was sore...

...

At the same time, the Google headquarters is thousands of miles away.

"Ding Ding!"

A sudden knock on the door sounded.

The president sitting on the sofa immediately stood up, opened the door on his own initiative, and found that a middle-aged white man standing outside the door, with his pupils suddenly shrunk: "Doctor Bo...Doctor, did you succeed?"

"Yes." The middle-aged man pinched the old brown suit on his body and focused his head: "It's successful!"

"yeah!"

“yes!”

"roar!"

Upon hearing this, the president immediately vented his excitement in his chest regardless of his image: "yes!yes!yes!!"

The middle-aged white man couldn't help but smile and watched the president jump around.

After a while, the president raised his wrist and looked at the time.

February 3, 2021...

"Quick! Take me there!"

"good."

The two immediately walked out of the office, surrounded by two bodyguards and several assistants, entered the special elevator, dived to the first floor of the headquarters, took a bulletproof car through the back door, and entered the warehouse.

In the warehouse, there are live ammunition mercenaries.

"You guys stop here."

Get off the car and stop the assistant and bodyguard from following, the president followed the middle-aged white man into the deep alley alone.

"President, here."

"Um."

In front of a heavily guarded steel gate, the president and the middle-aged white man had their identity certification, and the door was slowly opened.

Cheng, the iron gate made no sound.

"Um."

For some reason, the president's original excitement suddenly became terrifying.

In his eyes, the iron door that slowly opened seemed to have turned into a terrifying Pandora's box, choosing people to eat...
