Eighteen children on the Loess Plateau are still suspended in an endless space as a set of virtual data at this time.

The space was full of magnificent colors, and in this color was endless emptiness.

The children couldn't help but want to hold hands with their partners.

But the body that seemed to be became empty at this time.

Their hands passed through each other's bodies without resistance.

That's when these children felt indescribable fear.

The flagship brain quickly responded with a targeted response, discovering that these living beings could only relax and express themselves freely in their familiar surroundings.

As a result, a blue sky immediately appeared in the space where the children were, and the sky was like a huge blue crystal lid, which made people feel extremely pure and peaceful when they saw it.

But there was still no dirt under the children's feet, and there was the same blue sky above them.

They seem to be in a blue universe at this time, and there is no concept of going up and down, left and right.

The brain found that these living beings were still in fear.

It took a billionth of a second to analyze and finally came to the right conclusion.

Unlike most life forms in carbon-based federations, these organisms cannot control the mass-dependent attraction between objects.

Therefore they cannot be suspended in the void, they are beings who can only survive on the earth.

So the brain had space for the children, created a piece of earth to come out, and simulated the attraction of the blue planet for them.

The children were amazed to find a piece of earth suddenly appear under their feet.

The land was pure white, with neat squares drawn out of black lines, as if they were standing on a huge Go board.

A few of the bold ones squatted down and touched the ground.

It was smooth ground they never imagined.

When they walk, the soles of their feet are completely unable to move them forward, and no matter how fast they walk, they can only stay still.

This is an absolutely smooth flat surface, so the friction force is zero.

A mischievous child took off his shoe, lightly aimed it at the ground, and threw it forward.

The shoe moved in a straight line at a constant speed, and it slashed towards infinity.

The children stared blankly at their shoes, which gradually disappeared from their vision at a constant rate.

Is this Newton's first law?

Some smart children have already begun to "apply what they have learned".

At this moment, a voice suddenly appeared in their ears, and that ethereal and melodious tone, like an immortal Buddha, echoed in the ears of each of them.

"Now for the Level 2C Civilization Test.

2C Civilization Test Question No. 1: Please describe the way life on your planet evolved, is it a natural elimination type or a genetic mutation type?"

The children are at a loss, they haven't learned the subject of biology yet.

"2C Civilization Test Question No. 2: Please explain the source of the star's energy according to your own understanding. ”

The children are still at a loss, which is knowledge that falls under the category of high-energy physics.

……

"3C Civilization Test Question No. 9: Please explain the molecular composition of the liquids that make up the oceans on your planet. ”

The children were already on the verge of crying, they had just graduated from primary school.

"That's it! They won't be able to complete the 2C civilization test. ”

On the flagship, the fleet commander said to Peng Yichen, "We don't have time to delay any longer, otherwise we will probably not be able to complete this mission." ”

It's not that he can't wait for question 10, it's just that he's upset by the Supreme Consul's unusual behavior today.

Peng Yichen didn't look at him, only used his intelligence field to send out a faint vibration: "Complete the test of question 10!"

At this time, the senator also took his attention back from another star system that had just been destroyed.

In that star system, there is a planet with brainless worms living in mud.

Unfortunately, they did not pass the test of the 2C civilization, and could only disappear into the universe with their stars.

"Since the rule is 10 questions, I think it's better to continue the test. The senator also echoed Peng's order.

The commander had no choice but to release his finger pressed on the Singularity Bomb launch button.

Let the brain ask the children the 10th question.

"2C Civilization Test Question No. 10: What is the relationship between the three sides of a right triangle on a three-dimensional plane?"

The children remained silent.

"It doesn't make sense, Your Excellency. Said the commander of the fleet.

"Give them one last question, and if you still can't answer it, I won't stop you again. Peng Yichen pondered for a thousandth of a second before sending out a message.

"2C Civilization Test Question No. 11: When an object is not subjected to any external force, what is its operating state?"

In the virtual space of the brain, the innocent voices of the children suddenly sounded.

"When an object is not subjected to an external force, it will remain at rest or in a uniform linear motion. ”

"2C Civilization Test Question No. 11 passed!3C Civilization Test Question No. 12 ......"

"Wait!" the senator interrupted Zhina's question, excitedly saying, "The next test question is to be selected within the range of the laws of classical mechanics." ”

When he said this, he turned to look at the fleet commander and asked, "Isn't this a violation of the test guidelines?"

"Of course not, as long as it is a test question in the test database, it does not violate the rules. The fleet commander replied subconsciously.

He then devoted his attention to these beings that surprised him.

"2C Civilization Test Question No. 12: What is the relationship between forces between two interacting objects?"

In the virtual space, the children read aloud, just like in class: "When an object exerts a force on a second object, the second object will also exert a force on the first object, and the two forces are equal in magnitude and in opposite directions!"

"2C Civilization Test Question No. 12 passed!"

Although they answered two questions correctly, the children had already passed the test.

But the surprised fleet commanders, senators, and officers on duty did not give the order to end the tests.

Zhi Brain could only continue to test: "2C Civilization Test Question No. 13: Please explain the relationship between the mass of an object, the external force and the acceleration. ”

The more the children spoke, the more fluent and louder they became: "The acceleration of an object is directly proportional to the force it exerts and inversely proportional to its mass!"

"The 2C civilization test question passed on the 13th, and the civilization has reached the 3C civilization standard, do you want to continue the test?" asked Zhi Brain.

The fleet commander was already sweating profusely at this time, and he had just almost destroyed a civilization above level 3C.

If it really causes that terrible consequences, not to mention what the Federal Assembly will do with him, even he himself will regret it for the rest of his life.

As soon as he thought of this, he looked at Peng Yichen with great gratitude.

He thought that Peng Yichen had dissuaded him just now because he had a premonition of the strangeness of this civilization, so he saved him.

"We nearly destroyed a carbon-based civilization. The senator let out a long breath and said sternly to the commander of the fleet.

"I'm sorry, I was in a hurry. It's really incredible, there is a 3C-level civilization in such a desolate place!" the fleet commander wiped away his cold sweat and couldn't help but sigh.

"Yes, I haven't heard that the carbon-based federation and the silicon-based empire have plans to expand and cultivate civilization in this star field. It would be surprising if this was a civilization that evolved on its own. The senator said with some curiosity.

"Your Excellency, did you already know that this civilization is more than 3C? The fleet commander still couldn't help but ask.

Peng Yichen shook his head, "I don't know, but there is a consciousness that tells me that this civilization must be extraordinary." ”

The fleet commander nodded, and remedied an order: "Duty officer, send more probes to conduct a full-surface civilization test on Planet 3." ”
