Outside the door was a large hallway, and the equipment room was right in the middle of it, and the corridor stretched on either side into the lightless darkness.

Sputnik 1 produced more scout birds, and hundreds of birds swarmed out and flew all over the pyramid. As the scout bird explored little by little, the map gradually opened, and a complete pyramid appeared in front of Meng Yang.

The pyramid is hollow, and in the middle of it is a huge open space, with dozens of small compartments near the walls, as if an oversized atrium was built inside the building, which instead became the main body of the building. The equipment room is located right in a compartment at the waist of the pyramid, which is mostly open.

At the bottom of the atrium is an alien city, with miniature pyramids of all sizes, surrounded by rivers and hills, like a cityscape.

Through the vision of the scout bird, Meng Yang saw a city that had perished in the apocalypse, an alien city with scattered vehicles, collisions and damage everywhere.

Some of the buildings have obviously been baptized by fire, and even after nearly 10,000 years, the traces of fire are still clearly engraved on the buildings.

In all corners of the city, there are a large number of alien skeletons scattered there, which are withered and fragile after a long period of baptism, and will shatter at the slightest touch.

The skeletons were lying on the street, trapped in vehicles, torn apart, struggling and twisting......

Around each skeleton, there were many insect corpses of different shapes, which had been shriveled and brittle, and could easily be twisted into powder.

There is not much left of the laundry, most of them only leave some dust in place, and the dust that has accumulated together can barely see the outline of the clothing.

"Doctor Octopus, restore the appearance of aliens."

"Yes!" Doctor Octopus agreed, and soon several reduced pictures of aliens appeared in front of Meng Yang.

This is a humanoid creature, the limbs are very similar to humans, these aliens are estimated to be related to Liu Bei, each arm is longer than the knee, the head and neck are small, and the height is generally more than four meters, this is a giant race.

"Doctor Octopus, can you restore what happened?"

"I'm working on it!"

It didn't take long for Doctor Octopus's voice to sound.

Judging from the alien remains and various signs, the aliens suddenly encountered an accident, some aliens died on the spot, the city's energy was cut off, and a fire broke out. The few remaining aliens did not last long, dying in the years that followed. ”

Changes...... Maybe someone smashed a few big Ivan directly on the top of the city, right?

The real reason for extinction is probably in energy, otherwise such a large city will always be able to find some self-reliant equipment. Perhaps the energy cutoff and fires quickly deteriorated the atmosphere inside the pyramid, causing the ecosystem inside the pyramid to collapse in a short period of time. Once the ecosystem collapses, even if the energy source is repaired, the aliens are probably dead.

And the civilization of interstellar travel has been realized, the social division of labor unions is more refined, and the planetary colony base is a master of science and technology. A planetary base, I'm afraid it's not so easy to repair, not to mention whether the maintenance equipment is complete for the time being, whether the remaining alien specialties are the right is a big problem.

Anyway, this group of miserable aliens was destroyed by someone, and it doesn't matter who killed them or how. However, judging by their humanoid appearance, the aliens must have had some kind of communication with the ancient Indians and ancient Egyptians, allowing the pyramids to be transmitted to Earth.

Or maybe it was a few surviving aliens who fled to Earth and personally gathered the indigenous pyramids to build them?

It's like playing a charade, except for thinking is guessing, there is no answer to the question, you don't know whether you are right or wrong, right or wrong is also based on guessing, in addition to guessing or guessing, it is always equal to a philosophical game...... Headache! The egg hurts!

"Sputnik-1, see if you can find a transcript?"

After receiving Meng Yang's instructions, a group of scout birds burrowed into various buildings in the city and began to search for various records of the alien ruin's return.

All kinds of signs appeared in front of Meng Yang first, and only then did he realize that he was stupid again. Even if you find a written record, it won't work, you have to translate the language of the other person first. Linguistics is too far away from Meng Yang's world, and I don't know if I want to interpret it.

Translating the language of aliens......

Meng Yang suddenly thought of another question, is it necessary? Is it necessary for him to spend a lot of energy translating alien languages?

This alien is obviously a scientific and technological civilization, and he is following the standard path of biological civilization, even if he cracks the alien language and gets other people's technology, and then what? ...... Is it used for eggs?

Can you help him with his homework? Or can it help him get a perfect score on the exam?

Chicken ribs!

Meng Yang suddenly found that he had been exploring this pyramid, and he had been busy for a long time, and it seemed that he had no use except to satisfy his curiosity!

But since it's already here, let's finish exploring, and when the Scout Bird completes the entire pyramid, Meng Yang throws the data to Doctor Octopus and lets it analyze it slowly.

Before leaving, Sputnik-1 sealed the hole drilled in the pyramid, this pyramid itself is not needed, but maybe when humans colonize the moon, you can also carefully study this alien civilization and obtain the civilization heritage in the ruins.

After studying the pyramid and satisfying the curiosity of the hunter, Sputnik-1 began to return.

When Sputnik-1 returned, it was a full circle fatter than when it went, because it carried nearly a ton of helium-3 collected on the moon.

Although the weight of this ton of helium-three is not large, the energy contained in it is enough for Meng Yang to use it for a long time, and if these helium-three are thrown into the nuclear fusion cavity and the reaction is complete, it can almost release energy equivalent to 20 million tons of standard coal.

Helium-three fueled and fusion cavities do not release nuclear radiation, and with these helium-threes, Meng Yang can play with some high-power nuclear engines or use nuclear equipment in the city.

When Sputnik-1 flew out of the far side of the moon with blue majesty, the astronomical telescopes of various countries immediately discovered its traces, and countries quickly measured its trajectory - it was going to return to Earth!

Didn't the Great Yuan Empire always deny it, deny it all the time, and never admit that this spaceship was theirs?

Now that the spaceship is going back to Earth, see where you go!

The countries kept an eye on Sputnik-1, waiting for it to land in the territory of the Great Yuan Empire and then rushed to slap it in the face.
