Chapter 257 Hidden Message

Three metal nuts were strung together by the lizardman leader as ornaments!

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

Even the eight soldiers were stunned. It was dark at the time, and no one would care that the lizardman leader had a metal nut hanging around his neck!

What does this represent and what does it mean?

Everyone's mood is no longer "shocked" and it is simply unbelievable!

After a while, Dr. Rambo stood up and questioned loudly: "No, no, no, I believe it is because of human activities... These lizards just picked up the metal garbage we left behind!"

"There are a lot of reconnaissance drones and robots on the surface of our human beings. Maybe they picked up some replaced parts. This possibility also exists!"

Yu Yifeng nodded and felt that there was some truth. He quickly turned around and asked several engineering experts: "Can you figure out the type of parts in the picture, or the material texture? Can you figure out if it was left by us?"

"This... is difficult!"

Several material science experts looked at each other in bewilderment. They didn't have the real thing in their hands, and they wanted to distinguish the material of the parts based on a few blurry pictures? This is almost impossible!

But they still took the picture and studied it, trying to find some clues. Human parts are marked with subtle numbers, and they tried to figure out whether these nuts have numbers.

"No, Dr. Rambo! Your conjecture has a lot of loopholes."

The speaker was Wang Yufan from the Propaganda Department. He was also very excited and said: "These lizardmen are obviously creatures that hate cold. In order to save energy, they usually don't run to the cold surface to carry out activities..."

"And our robots usually move on the surface. Even if the mechanical parts are lost, it is impossible for them to fall seven or eight hundred meters underground... and then be picked up by them, right?"

"This possibility is too low!"

"Yes, you are right."

Rambo unexpectedly did not refute, but spoke enthusiastically.

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

"Its technological level is difficult to estimate. It is possible that it has surpassed us from the Industrial Revolution to the modern era! After all, this simplest nut is still used in many of our machines... In the foreseeable future, they will not be eliminated."

As soon as Rambo's words came out, everyone became excited, shocked or worried, with all kinds of emotions.

If the stupid lizard people can be easily controlled, then what about a more powerful civilization?

What about a civilization with an unknown level of technology?

Will humans face a war?

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

Another scientist stood up and refuted directly: "We did not observe any satellites above the atmosphere of the planet Nix! How powerful can a civilization without satellites be?"

"That's not certain. They live hundreds or even thousands of meters underground and can't find satellite signals. What's the point of launching satellites?" A congressman whispered below. He thought that underground people didn't need satellites.

Everyone present had different opinions, each with their own views, just like a brainstorming session.

Soon, all kinds of crazy ideas came out.

But the vast majority of people believed that if this unknown civilization existed, its technology must be much lower than that of humans!

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

Could it be that this unknown civilization is not interested in the endless space at all? Without such curiosity, their development potential must be quite limited, and they may not even have modern science!

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

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

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

"This civilization was once glorious, and there was a satellite system in the sky, but later for some reason, the civilization was extinct. Then the native lizards were born!" Dr. Rambo began his free speech again.

Whenever it was his turn to have a wonderful idea, he could always pull out something that others could not think of...

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

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

When the satellite's speed is lower than a certain speed, it will fall down. In other words, every artificial satellite has a life span.

Well, Rimbaud's conjecture is pure nonsense, but it sounds reasonable, at least there is such a possibility.

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!
