This answer made Zhuge Yun feel both expected and unreasonable.

He already had a feeling that the level of civilization of the other party, or the level of technology, was far beyond his own cognitive level. As for how much, because there is no specific object to compare, there is no clue at all.

"I have guided races like you, when your world was young." The voice said.

Zhuge Yun was so shocked that he trembled, and even his voice changed tone, and asked, "Please wait, our race?" Do you mean us humans? Our world was young...... What is the meaning? ”

The other party didn't reply, and Zhuge Yun guessed that it might be thinking, or doing something else? Anyway, the waiting time was too long, so long that he couldn't hold it back in his heart, so he asked again.

Still unanswered, is it because this question is so difficult to answer?

He changed his mindset and thought of another question and asked it carefully.

"Now, I think you know what you want to know about our civilization, can you answer my previous question?"

"Of course you can, but with the structure of your knowledge, the more you know, the more confused you may become." The other party finally "came back to life", and the voice began to speak.

"Perhaps, but you won't realize how eager and eager we are to learn through superficial data."

Zhuge Yun had already decided that the other party would not understand everything just through those questions and answers—how powerful the learning ability of human beings is.

There was another point that he didn't say: through the way the other party asked and the tone of his voice, he had a feeling that the other party seemed to be a feeling similar to artificial intelligence, rather than a living creature.

"Remember my previous question? Who are you? What is the purpose? Zhuge Yun tried to adjust the rhythm of his breathing, and asked in one breath.

"Of course you remember, as you wish."

As soon as the voice ended, the light and shadow in the space that was as empty as a giant library began to change, and in an instant, a surprising scene was revealed.

He raised his head and looked up, and beneath the darkness was a slowly rotating blue planet, which seemed not far away, and his eyes were watching the light rising in the universe.

Zhuge Yun saw a starry sky in front of his eyes, and in front of him, a red and scorching light advanced from the sea to the earth, like the rising sun.

There is no doubt that this familiar blue planet is Earth, but the question is - where is this Earth seen from?

Could it be the moon?

No, it can't be, there are mountains, seas and plants in the place where he is, it is exactly the same as the earth, and the earth is under his feet.

The thermonuclear reactions of stars all the time emit tens of millions or even hundreds of millions of degrees of heat in the cold and boundless universe, like a small light bulb hanging in a huge cold storage.

Zhuge Yun recognized that the star was the sun, which was slowly rising from the back of the earth, and the planet was shrouded in bright light displacement, emitting light and heat, instantly illuminating the fog of the southern hemisphere and dispelling the twilight of the night.

When the fog cleared, the vision gradually became clearer, and a vast land in the midst of drought was busy with a group of creatures.

This is exactly the creature I had seen on the "Pacific" before, with a cone-shaped body, a mollusk-like body, covered with carapace-like things in some parts, and a few tentacle-like limbs, which should have sucker-like tissues at the top, attracting some strange-shaped tools.

Unknown "construction tools" were carried high into the air by another group of elytra-like creatures, and were put together and assembled in places where there was no top.

Their slender arms seemed to be extremely strong, and it was a structure that looked like a black tower, and even a rough estimate estimated that there were millions or even tens of millions of such creatures, densely surrounding the tower, which was thousands of meters high.

Their figures cast black shadows on the sand, making the color of the land noticeably darker than the rest of the place.

The spiral-shaped wriggling elevator attracted the black plate like a magnet, and was sent into the black giant tower in a very orderly manner at a certain height.

Just like the conveyor belts and industrial robots in the factory, they are busy and orderly.

To be able to control such a large scale of creation, they must have a very high degree of computing power, and their fault tolerance is obviously incredible.

Zhuge Yun had been counting the "conveyor belts" shuttling back and forth, staring at their movement trajectory until he was dazzled, and he didn't see any mistakes.

After the elevator has finished moving one batch of supplies, it begins to transport another batch, repeating the previous action in a higher place, and is caught by the conical creature waiting on top with its tentacles, and magically combines them into the shape they need.

And so on and so forth.

This huge black tower was built little by little, and according to the construction speed calculated by Zhuge Yun, this efficiency was at least a hundred times higher than that of human beings, and not only these black towers, but also other places were also a busy scene.

It was a black city built with the same working methods, rising from the ground in the distance, in the surrounding area where the giant tower was built.

It turns out that this is how the Black Holy City was born?

But what does that mean?

Why did that voice show him this kind of thing?

Next, he saw the process of producing raw materials - these creatures smelted building materials in a peculiar way, using high temperature heating in the "workshop" to melt metals and minerals, and then using a large amount of mist to open up other unknown "tools", and then the excess fog was absorbed by the multicolored light, everything seemed to be under a high degree of precise control.

In this unique way, they are getting a kind of "dark crystal rock" that they can use to build their great "dark crystal" city.

It looked like a calm ocean with a blue glow in the distance, and the black water turned a deep blue near the shoreline.

So, where is this place?

He watched the building materials being melted and didn't have time to think about them.

Regarding the material, Zhuge Yun didn't know anything about it, only that it was refined from the material on this planet, and they seemed to be particularly fond of those synthetic polymer materials with high density.

In addition, there are some oddly shaped devices that are neatly arranged, even at the same intervals, and transported to the huge black tower in the midst of the hustle and bustle.

Those devices are like artificial intelligence devices invented by humans, or "hard drives" for storage devices, Zhuge Yun guesses, probably to record the knowledge they have collected from all over the universe, the history of races, the origin of civilizations, and so on.

Those elytra were most likely slaves or servants of creatures with conical bodies.

It's not difficult to make this judgment, and Zhuge Yun has a good basis: those cone-shaped creatures wear shiny devices on their heads, and there are some things like old-fashioned cameras on their wielding tentacles, and any human with similar experience will definitely think that they are weapons when they see them.

Although the elyopters were numerous, they still carried out their work in an orderly manner, and not one of them was lazy, or stopped by mistakes or conversations.

In fact, Zhuge Yun has never seen any mistakes in their work during his long-term observation.

Orderly, neat, and organized, this is their working state, or rather a kind of work rhythm.

When Zhuge Yun was watching some scenes, in addition to being dazed and shocked, he kept thinking in his mind: Did these images really happen, or were they made up? If so, where and when?
