Three metal nuts, strung together by the chief of the lizards, act as ornaments!

When you see the thread above, everyone has their mouths wide and is in a wonderful state of vertigo.

Even the eight soldiers were still stuck.At that time, the black light was blinding, and no one would care that the lizard leader was hanging around his neck... it was a metal nut!

What does this mean, what does it say?

Everyone's mood is no longer "shock" this word can be described, it is unbelievable!

After a while, Dr. Lanbo stood up and shouted, “No, no, no, I believe more that it is because of human activity... these lizards just picked up the metal garbage we left behind!”

“There are a lot of our human reconnaissance drones and robots on the surface, and maybe they have picked up some replacement parts.This may even exist!”

I nodded my head and felt some reason.He hurried back to a few 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 what we have left?”

“This... is hard!”

Several experts in materials suddenly looked at each other, they did not have physical objects in their hands, and they wanted to distinguish the parts and materials by just a few blurred pictures.It’s almost impossible, please!

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

"No, Dr. Lambo!Your guess is very flawed.”

Wang Yufan of the Propaganda Department, who also said with great excitement: "These lizards are obviously cold creatures, in order to save energy, usually they do not run to the cold surface for activities..."

"And our robots are generally active on the surface, and even if the mechanical parts are lost, they can't fall to the depth of seven or eight hundred meters underground... and then they are picked up?"

“The probability is too low!”

"Yes, you are right."

Rambo unexpectedly did not retort, but said feverishly.

“If they don’t have parts of our humans around their necks, then ... is there a more powerful unknown civilization on this planet!”A civilization more powerful than the lizards, entering the mechanical age!”

Its scientific and technological level is incalculable, from the era of the industrial revolution to the modern era and even beyond us!After all, this simplest nut is still used in many of our machines... They will not be eliminated in the foreseeable future.”

As soon as Rambo said that everyone suddenly became excited, shocked or worried, and there were all kinds of emotions.

If the silly lizard man can still be easily controlled, what about a more powerful civilization?

What about a civilization with an unknown level of technology?

Will humanity face a war?

“No, Dr. Lamborghed, I think ... even if this unknown civilization does exist, its level of technology will not surpass ours!”

Another scientist stood up and retorted, “We’re not observing any satellites above the atmosphere on the planet Knicks!”How powerful can a civilization without satellites be?”

"That's probably it, they live a few hundred meters or even a kilometer underground, and they can't find satellite signals."What is the use of launching satellites?”A lawmaker whispered below that he did not think the underground people need a satellite.

Everyone here has different opinions, and each has its own words, just like brainstorming.

Soon, all the messy ideas came out.

But the vast majority of people think that if this unknown civilization exists, it must have much lower technology than humans!

Satellites, not only the Global Positioning System, but also the space station, astronomical telescopes and so on.

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

Or that is, their level of technology is not enough to reach the level of launching satellites.After all, the atmosphere of the Knicks is thick and the gravity is high, and it is much more difficult to launch a satellite than the earth.

Moreover, people have not found any large buildings on the surface of the earth... will the underground high-tech civilization never drill out of the ground?

There is even another way of saying that this civilization is extinct!

"This civilization was once brilliant, there was a satellite system in the sky, but then for some reason, civilization was mass extinction."Then came the birth of the indigenous lizards!”Dr. Lambo began to speak again.

Whenever it’s my turn to whimsy, he can always pull out something that others can’t think of...

"The satellites in the sky may have existed, but once the life is reached, they are attracted to the earth, and they all fall, which is also possible..."

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

When the satellite velocity is below one speed, it falls off.In other words, every satellite has a lifetime.

Well, Rambo's conjecture was purely a bit of a mess, but it sounded so much, at least that possibility.

Even in other psychological terms, it makes a lot of sense.

The reason is nothing more: survival competition!

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

But can two native intelligent beings really live in harmony?

According to human understanding, it is difficult.Especially on this barren, lack of light, lack of energy on the planet, the competition for survival is too great!

Just like human society, if a intelligent monkey with intelligence was found on Earth... what would humans think?

The whole human society will surely panic and be shocked!Even a massacre is possible.

The rise of the orangutan is not so easy.

Even if humans are tolerant and do not engage in genocide, these intelligent monkeys will be strictly monitored and even enslaved to prevent their rise from threatening humanity.

After all, this is two races, between race and race, there is no morality of righteousness!

But now, although these lizards have a difficult life and seem to be very free, they can even send eight people such as Wu Hao out of the earth.This shows that no one limits or enslaves them!

So Dr. Lambo’s conjecture makes a bit of a sense that this unknown, powerful civilization may have become extinct.

Of course, these smart heads here have come up with other strange ideas...

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

The remnant of a true interstellar civilization!

No trace of an alien spacecraft has been seen on the surface or in space.So these interstellar civilizations may have come to this planet to investigate and then go away.

They left only these useless parts, and as a result, these indigenous lizards regarded as treasures and passed down from generation to generation as ancestral treasures.

It is also possible!

There is also a saying that an alien spacecraft falls on this planet... and humans can start picking up garbage again...

Yu Yifeng covered his head, and he felt that this possibility seemed to exist.

Since the solar system is an interstellar battlefield of an alien civilization, this star system, more than 20 light-years away, may have once been an interstellar battlefield... No one knows how many light-years can be extended between interstellar civilizations.

Well, so, all corners of this star domain are full of alien spacecraft debris.

Or is it human luck particularly good?

“There is a result!”Just as the heated discussion was over, an expert in materials engineering shouted: “It can be seen from the pictures that the surface of these nuts is full of rust!”I didn't see our number."

It is not easy to get this result, from a bleak black and white light, it can be seen that there is no rust in a small nut, which requires a lot of modeling and comparison calculation.

“The whole nut is full of rust!”Some places are worse and look very old.And such rusty marks cannot be left behind by us as humans.”The engineer swore.

His subtext is that our human material can't be so rubbish, it can't rust like this in two months...

Even if the environment is worse, it can't rust like this!
