After a while, A Qing came out of Pang Xuelin's arms, and a little pink face flushed.

Pang Xuelin couldn't help pinching her face and smiled, "Aqing, how would the report over Princeton feel?"

A Qingdao: "It's okay, just a bit boring. When attending the reception, the men who talked with each other were annoyed. Professor Deligne also asked me if I would like to work in Princeton. I am not so stupid. Now we are The Tsinghua Advanced Institute is no less than their Princeton Advanced Institute. "

Xi Pang Xuelin smiled, although from the bottom line, the Princeton Advanced Institute is much deeper than the Tsinghua Advanced Institute.

But over the years, with the research of graphene, carbon nanotubes and neutrino oscillations found in the Daya Bay laboratory, Tsinghua University has produced several Nobel Prize results.

In addition, Pang Xuelin also successfully predicted and formed experimental teams to observe the quantum spin Hall effect in two-dimensional topological insulators and the quantum anomalous Hall effect in magnetically doped topological insulators.

These two results are not much worse than the previous ones.

Some people in the scientific community have predicted that Pang Xuelin is likely to win the Nobel Prize in Physics after receiving the Nobel Prize in Chemistry, becoming the only Nobel Prize winner in history. (Historically, the Nobel Prize winner is Pauling, who has won the Nobel Prize in Chemistry and the Nobel Peace Prize respectively.)

Because of the existence of Ponzi geometry, the Tsinghua Advanced Institute is already a mathematical center in the world that can compete with the Princeton Advanced Institute. The Ponzi geometry school is famous in the world.

Pang Xuelin said with a smile: "My home is the best, even Princeton Advanced Research Institute doesn't look down on it. By the way, if you come back to Tsinghua this time, you should be able to directly give an associate professor a Ph.D. guide, and the school needs to arrange a teacher for you No apartment? "

Aqing blinked and looked at Pang Xuelin with tears: "Brother, do you want to kick me out again?"

Immediately, A Qing turned her eyes to Wang Muhui and said, "Sister Hui, my brother wants to drive me away."

"Okay!" Wang Muhui gave Pang Xuelin a strange look and said, "A Qing, this is your home. You can live as long as you want, don't care about your brother."

"Long live Xiao Hui! Sister Xiao Hui, what shall we eat tonight? I help you cook together."

Aqing went up and hugged Wang Muhui's cheek and smelt sweetly.

Xi Pang Xuelin shook his head. For Qing Qing's mind, no matter he or Wang Muhui, he could vaguely feel it, but no one was clear.

He has tried to transfer A Qing to the field several times, but often A Qing pretends to be poor in front of him and Wang Muhui, and he has no choice.

The rice dumplings are very hearty, with oiled prawns, cola chicken wings, steamed sea bass, chives and scrambled eggs, plus an egg soup.

The family of three sat around the table and talked while eating.

But Pang Xuelin never thought that the civilization level test that he had been thinking about all of a sudden began at this moment.

宿主 "Host, please note that the carbon-based life alliance Blue 84210 is detecting the earth, and the detection beam is about to reach the target."

Suddenly, the sound of the puppet system rang in Pang Xuelin's mind.

Su Pang Xuelin's movements were frozen for a moment. The next second, Pang Xuelin found that not only himself, but also Wang Muhui and Su Anqing beside him also stopped.

Wu Suanqing was sending a piece of chicken wings to her mouth, and a drop of sauce dripped from the chicken wings and solidified in the air.

In front of Wang Muhui, the white water mist she had just soaked in a glass of hot water she had just soaked in was also frozen.

Soon after, Pang Xuelin found that his perspective was slowly rising.

He lowered his head and looked down. His body was still sitting at the dining table, but a transparent self floated out of the body.

As soon as Xu Pang Xuelin turned his head, he saw that Su Anqing and Wang Muhui's transparent bodies also floated out.

He is as if the soul is out of touch.

系统 "System, what's going on?"

宿主 "Host, don't be alarmed. The host has been selected by the Carbon-based Life Alliance to participate in the civilization level test as a representative of the Earth's civilization. What comes out of your body is only your digital copy."

"Look!"

Pang Xuelin was speechless.

In the novel, after a tens of thousands of years of war between the carbon-based life alliance and the silicon-based life alliance, the silicon-based life alliance was defeated and was driven to the edge of the galaxy.

The Carbon-Based Life Alliance has decided to establish a 10,000 light-year barrier in the Milky Way, destroying hundreds of millions of stars, and building an interstellar Great Wall of 10,000 light-years. It is used to prevent the silicon-based life alliance from using the star frog to launch a counterattack against the carbon-based life alliance.

In order to prevent accidental damage to civilizations above the 3C level, the Carbon-based Life Alliance conducts civilization level tests on living galaxies.

In the novel, the children in that group of rural elementary schools were selected to participate in the civilization level test. In the end, because of the Newton's Three Laws that the teacher gave them before death, the human civilization survived the crisis of destruction.

Because of being unable to determine the chosen target, these years, Pang Xuelin can only strive to improve the education level of primary schools in poverty-stricken areas across the country to cope with a possible crisis.

But he didn't expect that after doing so many preparations, he was finally selected, who was himself.

"Does the system cheat itself?"

Pang Xuelin was a little bit crying.

的 The test questions in the novel are not difficult. Under normal circumstances, middle school students can answer them.

The only thing that makes Pang Xuelin somewhat strange is that according to the scenes in the novel, the selected digital replica has the complete memory of the ontology and does not have the sense of autonomy.

But now, after being selected, he is still awake.

Is this a benefit to the system?

In the novel, the Carbon-based Life Alliance is a super civilization that has mastered technologies such as stellar frog jumping and four-dimensional communication. It is a pity to let go of such an opportunity to make contact with higher civilizations with ease.

If you try to communicate with the Carbon-based Life Alliance during the test, what will happen next?

Pang Xuelin's eyes narrowed slightly.

In fact, in the past few worlds, there has always been a question in his mind.

三 "Three-body", "Mars Rescue", "Wandering Earth", "Village Teacher" ... Are these worlds real or systematically simulated?

到底 What kind of existence is the system?

These doubts have been in Pang Xuelin's mind for many years, but there has been no clear answer.

"Yes, system, can I communicate with the Carbon-based Life Alliance while testing?"

Pang Xuelin said silently in his heart.

"Anything the host does in the plane world, the system will not interfere."

Xi Pang Xuelin could not help laughing.

What does the system mean, that is the default?

Uh ...

At this time, Pang Xuelin's perspective had floated from the villa to the city. The brightly lit city gradually became smaller in his eyes. Slowly, the outline of the Asian continent began to appear in his eyes.

As the perspective of Pang Xuelin continued to rise, a picture of the earth soon appeared.

The next second, Pang Xuelin felt the surrounding space suddenly become distorted.

He and Wang Muhui and A Qing seemed to enter some kind of strange cavities. The sun came in and became colorful.

But this process lasted only a few seconds, and Pang Xuelin closed his eyes with a dazzling light.

When he opened his eyes again, Pang Xuelin found himself, A Qing, Wang Muhui, suspended in an endless space, and that space showed an endless emptiness.

Tong Aqing and Wang Muhui seemed to be in a state of ignorance, and could not help but want to move closer to Pang Xuelin.

But they are all in the void, without any focus, they are useless for a while.

Perhaps the Carbon-based Life Alliance computer noticed this, thinking that these living things need something familiar, so Pang Xuelin discovered that a light blue sky appeared above them.

I still have sunshine and white clouds.

Then the earth appeared under their feet, and they began to feel gravity.

But the earth showed an absolutely smooth mirror surface. Pang Xuelin bent down, took off his shoes, and threw them out.

Soon, the shoes slipped ahead on the smooth ground in a straight line motion at a constant speed.

Suddenly, Pang Xuelin himself, because of momentum conservation, slipped back at a slower speed.

interesting.

Pang Xuelin did not expect that he actually saw Newton's first law here in the true sense.

At this time, an ethereal voice sounded in this digital universe.

"Begin the first-level civilization test, first-level civilization test question No. 1: Please describe the basic principles of the biological evolution of your planet, is it natural elimination or genetic mutation?"

"Natural Elimination."

I haven't waited for Pang Xuelin to answer, Su Anqing and Wang Muhui actually answered it as soon as possible.

"Test No. 1 passed. Level 1 Civilization Test No. 2: Please briefly describe the relationship between electricity and magnetism."

Pang Xuelin's eyes narrowed slightly. In his impression, the civilization test in the novel should be the 3C civilization test ~ lightnovelpub.net ~ and here, it has become a first-class civilization test.

The first question is basically the same as in the novel, but the second question begins and there are differences.

"A change in magnetic flux generates an induced electromotive force."

Pang Xuelin said.

"Passed in Test Question No. 2. First-level Civilization Test Question No. 3: Please briefly describe the relationship between electric and magnetic fields, charge density, and current density."

Pang Xuelindao: "In general, the electric field can be either a free electric field or an induced electric field induced by a changing magnetic field, and the induced electric field is a vortex field. Its electric displacement line is closed and the flux to the closed surface No contribution. Magnetic fields can be excited by conductive currents or by displacement currents of varying electric fields. Their magnetic fields are both vortex fields and magnetic induction lines are closed lines, which do not contribute to the flux of the closed surface. "

"Test 3 passed. Congratulations, the first-level civilization test passed ..."

Before waiting for that voice to finish, Pang Xuelin suddenly exclaimed, "Can you answer the second civilization test?"
