Beneath Deep Space

Three metal nuts were strung together by the lizardman leader and used as accessories!

When they saw the threads on it, everyone opened their mouths wide and were in a wonderful state of dizziness.

Even the eight soldiers were stunned. At that time, no one cared that what the lizard leader was hanging around his neck... turned out to be metal nuts!

What does this mean? What does it mean?

Everyone's mood can no longer be described by the word "shocked", it is simply unbelievable!

After a while, Dr. Rimbaud stood up and questioned loudly: "No, no, no, I believe it is more because of human activities...these lizards happened to pick up the metal garbage we left behind!"

"There are a large number of human reconnaissance drones and robots on the surface. Perhaps they have picked up some replaced parts. This possibility also exists!"

Yu Yifeng nodded, feeling that it made sense. He quickly turned back to several engineering experts and asked: "Can you figure out the type of parts in the picture, or the texture of the material? Can you figure out whether it was left by us?"

"This... is difficult!"

Several experts in materials science suddenly looked at each other. They didn't have any physical objects in their hands, so they wanted to identify the materials of the parts based only on a few blurry pictures? This is almost impossible please!

However, they still studied the picture, trying to find some clues. Human parts are marked with subtle numbers, and they try to figure out whether these nuts are numbered.

"No, Dr. Rimbaud! There is a big hole in your conjecture."

The speaker was Wang Yufan from the Propaganda Department. He also said very excitedly: "These lizard people are obviously creatures that hate the cold. In order to save energy, they usually do not run to the cold surface for activities..."

"And our robots usually move on the surface. Even if the mechanical parts are lost, they cannot fall to a depth of 700 to 800 meters underground... and then be picked up by them again, right?"

"This possibility is too low!"

"Yes, you're right."

Rimbaud unexpectedly did not refute, but spoke enthusiastically.

"If the parts hanging around their necks are not our human parts, then... maybe there will be a more powerful unknown civilization on this planet! A civilization that is more powerful than the lizard people and has entered the mechanical age!"

"The level of science and technology is difficult to estimate. It is possible from the Industrial Revolution era to modern times and even beyond ours! After all, this simplest nut is still used in many of our machines... In the foreseeable future, they will not be used Eliminated."

As soon as Rimbaud's words came out, everyone suddenly became excited, shocked or worried, with various emotions.

If the silly lizard people can be easily controlled, what about other civilizations that are more powerful?

What about a civilization whose technological level is unknown?

Will mankind face a war?

"No, Dr. Rimbaud, I think...even if this unknown civilization does exist, its technological level cannot surpass ours!"

Another scientist stood up and retorted: "We are above the atmosphere of the planet Nix and are not observing any satellites! How powerful can a civilization without satellites be?"

"That's not possible. They live hundreds of meters or even thousands of meters underground, and they can't find satellite signals. What's the use of launching satellites?" A congressman whispered from below, thinking that people underground have no need for satellites. .

Everyone here has different opinions and opinions, just like brainstorming.

Soon, all kinds of strange ideas came out.

But the view of most people is that if this unknown civilization exists, its technology must be much lower than that of humans!

Artificial satellites are not just global positioning systems, but also space stations, astronomical telescopes, etc.

Is this unknown civilization not interested in the endless space at all? Without such curiosity, their development potential must be quite limited, and there may not even be modern science!

Or, their technological level is not high enough to launch satellites. After all, Nix has a thick atmosphere and high gravity, so it is much more difficult to launch a satellite than the Earth.

Moreover, people have not found any serious large-scale buildings on the surface... Will the high-tech civilization underground never come out of the ground?

There is even... There is another saying that this civilization has become extinct!

"This civilization was once glorious, and there was a satellite system in the sky. However, due to some reasons, the civilization became extinct. Then the indigenous lizards were born!" Dr. Rimbaud began to speak freely.

Whenever it's his turn to have a whimsical idea, he can always come up with something that others can't think of...

"There may have been satellites in the sky before, but when their life span was over, they were attracted by the center of the earth and all fell. This is also possible..."

In fact, man-made satellites will fall sooner or later, because most man-made satellites are hundreds to thousands of kilometers away from the ground. Although the atmosphere there is very thin, friction still exists.

When the satellite speed falls below a certain speed, it will fall down. In other words, every artificial satellite has a lifespan.

Well, Rimbaud's conjecture is just a bunch of nonsense, but it still sounds reasonable, at least it is possible.

Even from another psychological point of view, it is quite reasonable.

The reason is nothing more than one: competition for survival!

The new human civilization is an alien colonizer, so it has a tolerant and curious attitude towards these local intelligent life forms.

However, can two local intelligent life forms really coexist harmoniously?

According to human understanding, it is probably difficult. Especially on this barren, light-deficient, energy-deficient planet, the competition for survival is too fierce!

Just like human society, if a kind of intelligent monkey with intelligence comparable to that of humans is discovered on Earth... what will humans think?

The entire human society will definitely panic and be shocked! It is even possible to trigger a massacre...

The rise of gorillas is not that easy.

Even if humans are more tolerant and do not engage in genocide, they will strictly monitor and even enslave these intelligent monkeys to prevent their rise from posing a threat to humans.

After all, these are two races, and there is no morality between races!

But now, although these lizards have a difficult life, they still look very free. They can even send people to send Wu Hao and eight others out of the surface. This shows... no one restricts or enslaves them!

So Dr. Rimbaud's conjecture makes some sense. This unknown powerful civilization may have become extinct.

Of course, the smart minds present here have come up with all kinds of other strange ideas...

For example, this nut was left by another alien civilization!

That is, the remnants of a true interstellar civilization!

At present, human satellites have not seen any traces of alien spacecraft on the surface or in space orbit. So these interstellar civilizations may have come to this planet to investigate and then left.

They only left these useless parts, but these native lizards regarded them as treasures, passed them down from generation to generation, and regarded them as ancestral treasures.

This is also possible!

There is another saying: an alien spacecraft crashed on this planet...Humans can start picking up garbage again...

Yu Yifeng covered his head, he felt that this possibility seemed to be possible.

Since the solar system is an interstellar battlefield of alien civilizations, then this star system more than 20 light years away may have been an interstellar battlefield...No one knows how many light years the war between interstellar civilizations can extend.

Well, according to this, every corner of this star field is full of alien spacecraft wreckage?

Or is human luck particularly good?

"We have the result!" Just as people were discussing it enthusiastically, a material engineering expert shouted: "From the pictures, we can see that the surface of these nuts is full of rust! We don't see our numbers."

It is not easy to get this result. From a dull black and white photo, it takes a lot of modeling and comparative calculations to see whether a small nut is rusty.

"...The whole nut is full of rust! Some places are worn out more severely and look very old. And such rusty traces cannot be left by us humans." The engineer said confidently.

His subtext is that our human materials cannot be so rubbish, and it is impossible for them to rust like this in two months...

Even in the worst environment, it is impossible for them to rust like this!
