"What are you doing on Earth?"

If there is an accurate answer to this question......

Then a lot of doubts may be able to wait for explanation.

As soon as the gray man gave up his struggle, he straightened his posture.

It didn't have the slightest hidden meaning, and said very bluntly:

"We are the ...... that collects breeding information on the planet"

"Our home planet has reached a reproductive stagnation."

Lu Yun listened to the gray man's explanation and was silent for a moment.

In fact, he was waiting for Ying Zheng's reaction, and if he lied, Ying Zheng would definitely be able to see it.

"Fertility stagnation ......"

"It's a possibility."

"Brother Zheng's reaction doesn't look like a lie......"

After Lu Yun made a simple judgment, through Brother Zheng's reaction, he could also see that he was telling the truth.

So, he nodded and continued to ask:

"Apart from you, who else has entered Earth from the Outlands?"

"What purpose are they all here for on Earth?"

"Why are they all kept secret?"

The gray man immediately replied:

"In addition to us, there are at least three hundred or so civilizations of similar rank operating on Earth......"

"Most of the purpose is to use the earth as a model to examine the problem of reproduction......"

"Some are simply to collect the genes of special intelligent species, and some are criminals who have been exiled to Earth......"

"The reason why we don't have contact with earthlings is because of the restrictions of the interstellar convention, and we can't affect the natural progress of earth's civilization unless there are special circumstances."

Lu Yun frowned, feeling that this was different from what he had grasped.

But immediately, the gray man added:

"In addition to these more than 300 low-level civilizations with similar technological levels to ours......"

"There are some higher civilizations."

"They took a fancy to the huge gold deposits on the planet that were easy to discover, and left the planet after they finished mining."

"That was hundreds of thousands of Earth years ago, and now it is the end of the Earth civilization, and our civilizations can only do the most basic observations and experiments......"

Hundreds of thousands of Earth years ago?

And what made Lu Yun feel even more wrong was the statement "the end of the earth's civilization".

This made Lu Yun frown.

However, according to the time span of hundreds of thousands of years, it may not be the so-called "end period".

At this time, Lu Yun's mind was sketching a ladder of interstellar civilization.

What the gray mouth described made him quickly compare it with some of the knowledge he had.

And the gray man's answer has not stopped:

"The view of the higher civilization on the people of the earth is divided into three directions."

"The vast majority of advanced civilizations believe that human beings should fend for themselves."

"This part of the higher civilization has this attitude towards any civilization."

"They don't care at all about the existence of other civilizations."

"A small group believes that the level of science and technology of mankind should be improved...... In this way, you can reach a level that can be integrated into an interstellar civilization. ”

"The other part believes that earthlings should be observed as experimental subjects, and if necessary, civilization can be destroyed and the birth and evolution of new civilizations can be re-examined."

Lu Yun's brows trembled.

These aliens look at earthlings......

It's like looking at an experimental creature in a cage.

But even so, the voice of the gray man is not over:

"A low-level civilization like ours does not have the power to participate in this kind of voting......"

"I can only get the answer from the Interstellar Convention."

"Those people of advanced civilization are all beings who have no feelings and no life limit."

"Most of them have completely cut off the need to reproduce, so they don't care what kind of answer the convention will give."

"Or, if the Convention orders the extermination of higher civilizations, they may commit suicide without resistance, or even voluntarily."

And listening to his words, Lu Yun also realized......

In this universe, there is a high-level existence called the "Interstellar Convention".

If you put an analogy on Earth, it is very much like the United Nations.

But of course, listening to what the gray mouth is saying, it is clear that this interstellar convention is not something as nominal as the United Nations.

The Interstellar Covenant sounds less like a literal restriction and more like a tangible supreme being.

This existence is restricting all intelligent life in the universe.

However, at this moment, the gray man paused for a moment before speaking:

"The spaceship on the back of the moon is clearly from some advanced civilization......"

"According to our superficial understanding of advanced civilization, it should be a mining ship."

"There won't be any living creatures in it."

"But for the vast majority of inferior civilizations, even such mining ships ......"

"It's not something that ordinary civilizations can fight against."

"It will disintegrate the bonanza planet for a moment, obtain all the minerals it needs, and then teleport back to the home planet."

After hearing the description of this mining ship, Lu Yun only felt his heart beating wildly!

Decomposing the planet?

And then send the minerals contained within a planet back to the home planet?

What level of technology is this?

And how did a cosmic mining machine with such powerful technology sink on the moon?

Fault?

Or is it an attack from another higher civilization?

What are you doing attacking a mining ship?

Lu Yun was puzzled in his heart.

However, it is clear that the answer to this question is not known to the gray man.

Their civilization level is too low to receive a real reason.

Lu Yun took a deep breath.

The mining rigs of advanced civilizations have the power to decompose planets......

And how terrible would it be if it was used as a weapon of interstellar warfare?

That's a level that even imagination can't reach.

This time I came to Xianqin, and I really benefited a lot.

However, although he benefited a lot, the answer he got deepened the haze in Lu Yun's heart.

It seems that if you want to get the real source of the earth's crisis, or even whether it is a "crisis" at all, you need to take a trip to the moon to have an answer.

However, there are other problems in Xianqin.

Before the start of the "Demon War" mentioned by Ying Zheng, those aliens left the earth en masse.

What is the reason for this?

Lu Yun opened his mouth again and asked:

"You should be very clear about the current situation on Earth."

"Obviously, you're ready to leave after seeing us......"

"Why are you leaving?"

The gray man also immediately gave an answer:

"The sample of earthlings is gradually becoming inaccurate......"

"And our own surveys are under threat."

"Evacuation in the event of a threat is in line with our evacuation requirements."

This answer may not fully explain the reason for the evacuation of all the alien civilizations before the Demon War, but it is obvious that it is the basis for those civilizations to leave the earth.

But what is more obvious is that this evacuation is very different from the message of the Orion civilization received by the Pyramid of Khufu "Escape from Earth".

At the same time, in the process of talking to these gray people, Lu Yun also noticed something different.

Although it may seem scary, the answers are fairly methodical.

gave Lu Yun a feeling that although he had feelings, he could carry all kinds of feelings very clearly.

It's as if the three emotions of anger, fear, and reason are in parallel in the mind.

It is fundamentally different from the human senses, which connect multiple emotions at the same time.

It seems that it is based on survival, and it is judging the optimal solution.

Is this the advanced nature of humanity?

Or is it a place where humanity is backward?

The civilization of the Greys, as far as we know so far, can clearly know that they are currently in a breeding crisis.

Civilizations that do not achieve eternal life will eventually die if they cannot reproduce.

Even if immortality is achieved, whether civilization can go further depends on whether it is enterprising.

At this time, Lu Yun opened his mouth again and asked:

"When did you come to Earth?"

"Do you already have the data you want?"

The gray man simply knew everything:

"My spaceship came to Earth a thousand years ago ......"

"There are no clues about the survival of the race at this time."

"We don't know where the problem is...... But there is not much left before complete destruction. ”

Lu Yun immediately asked:

"Why did you choose humans for observation?"

"Do you have any other observations besides us?"

The Grey Man explained:

"Humanoids are the biological samples that are most likely to develop into advanced civilizations."

"All kinds of humanoid creatures are found in the universe."

"Inferior humanoids like us......"

"The scientific and technological achievements that have been achieved now have reached the limit."

Hearing this, Lu Yun frowned.

Reached the limit?

How is this limit defined?

Could it be the Interstellar Covenant?

But he didn't dwell on that.

It is clear that this gray man does not know the answer to this question.

He asked a few more questions about the technology and the types of races in the stars.

And these questions have been answered to some extent, but they are quite ambiguous.

There are many main races of various civilizations in the universe, in addition to humanoid creatures and humanoid creatures, there are also many zergs, allomorphic and fluid races, and there are even civilizations that exist purely as conscious bodies.

As for the answer to science and technology, this gray man is just a small person responsible for collecting information, he only has a basic understanding, but he has no idea about the specific implementation plan and how to implement it.

This is understandable, of course, an expedition sent to an alien planet, they are no different from being exiled.

Immediately after, Lu Yun asked a most important question:

"As far as you know......"

"High civilizations and interstellar conventions, have they mastered the technology of time travel?"

And the gray man was stunned for a moment, and immediately shook his head:

"Time...... Shuttle? ”

"It's impossible."

"It doesn't make sense."

He made it very clear.

But when Lu Yun asked carefully, the gray man's expressionless face showed a blank look.

Thinkers

It seems that for the time ......

He only knew the term.

But there is no clearer understanding.

In other words, there is no sense of time.

It was difficult for Lu Yun to understand what it was like to feel like this.

Maybe this is also some kind of curse of knowledge?

But it doesn't matter.

Lu Yun needs to bring him back to this timeline.

The reason for bringing it back is naturally because Lu Yun's problem is too restrictive.

On the one hand, Lu Yun's focus is mainly on the "crisis".

For further exploration of technology and extraterrestrial civilizations, more professional people are still needed to ask.

If you catch a living body, of course, you have to use it to the limit.

However, before asking the First Emperor to hand him over, Lu Yun asked one last question:

"What you said about leaving the earth in one year, how many earth years is this year equivalent to?"

"In other words, when are you going to leave at the latest?"

The gray man, as always, immediately replied.

"The latest time limit is 1,850 years after the Earth year."

And after hearing this answer, Lu Yun only felt a bang in his brain!

That strange sense of fate surged through the whole body again!

The present time, BC217-A's Immortal Qin 200 years.

And 200 years after 1850 at this time......

Exactly 2050!
