At this time, even if the elevator could really work, Xu You didn't dare to enter the elevator easily.

After all, the whole device has been abandoned for many years. If the elevator breaks down suddenly, there is no one here who can rescue Xu You.

Xu You originally thought that there should be many floors of underground shelters here.

But when Xu You went down to the sixth floor, he found that there was no way down here.

"Is there only six floors? If you calculate it this way, the number of people that the entire moon can accommodate is..."

At this time, Xu You was running his brain quickly, thinking about this question quickly.

In fact, this question is not a question with clear conditions, because Xu You is still not sure about many things at this time.

Compared to the blue star, the moon is a smaller planet. The diameter of the moon is only three-eleventh of the blue star, and the surface area of ​​the moon is only about one-fourteenth of the blue star's surface area.

If you think in this direction, if you want to accommodate enough people, the number of floors of these underground shelters must be as many as possible.

But in fact, on the blue star, the land only accounts for about 29% of the total area of ​​the blue star, and most of the area on the blue star is covered by the ocean.

And those land areas, only a few are used for living.

Thinking about it this way, if most of the underground area of ​​the moon is used as a shelter, it can also accommodate a large number of people.

Even, even if all the eight billion people on the blue star live there, such a space is completely sufficient.

only……

"Could it be that this underground shelter has no other functions other than living?"

If it is a space station in the conventional sense, astronauts only need to stay in it for a few months, and naturally they will not reserve too much space.

But if it was an interstellar voyage, it would be impossible for people to stay in the room all the time, and Xu You had various other facilities.

The time required for crossing the interstellar voyage may be more than hundreds of years, and human beings have even passed down generations.

However, Xu You did not find any other space for activities other than the living room.

"Wait a moment……"

At this time, Xu You suddenly remembered the hypothesis that the interior of the moon may be a hole.

"Since there are no traces of development on the surface of the moon...then there should be geniuses in the interior of the moon..."

Thinking of this, Xu You continued to explore the underground shelter.

At this time, the oxygen and energy in Xu You's body were consumed to a certain extent, but Xu You had no way out.

Instead of worrying about gains and losses, it is better to find ways to unlock more secrets, because this is the only possibility to go back.

"The promise to go back in half an hour, I really can't keep it. If there is any way to get in touch with the outside, it will also make Yaoyao feel at ease."

While thinking, Xu You explored along a certain order, and remembered the surrounding environment in his brain.

Xu You's brain is very powerful, and can draw all the places he has experienced on the map in his mind in a three-dimensional manner, as if he had a high-precision map software.

Soon, Xu You learned more about the structure of the underground shelter.

Including air pipes, drainage systems, circulation systems, power systems and many other necessary systems for underground shelters, Xu You has found traces of them.

After discovering a large number of words, Xu You also gradually translated the possible meanings of some words.

Xu You once studied how to translate an unknown language in his spare time.

In theory, as long as there are enough samples, even in a completely unfamiliar language, a high translation accuracy rate can be achieved.

"If my guess is correct, this is the switch." Xu You said to himself.

However, no matter how Xu You controlled the switch, it did not cause any change.

Is the device already broken? Or is there no power supply at all? "

After listing several possible reasons, Xu You turned the switch back to what he thought was the open position, and continued to explore.

After another walk, Xu You got more information about the underground shelter.

The underground here is entirely used for living, and there are no open spaces, roads and other facilities.

And these refuges also have their own numbers, similar to the communities, districts, buildings, units, etc. on Blue Star.

Xu You knew that if the main switch of the switch was not opened, it would not make much sense to control only a few switches responsible for a small part.

"Huh? Is the switch here closed?"

At this time, Xu You discovered a master gate that seemed to control the entire "community".

With the information just obtained, Xu You can basically confirm that the symbol pointed by the electric switch should be closed.

With a hint of excitement, Xu You pushed the switch up.

In an instant, there were bursts of buzzing sounds in the entire underground refuge.

Then, the lights in the corridor came on.

"Electricity...started?"

Seeing such a scene, Xu You couldn't help being surprised.

Xu You didn't know how long the underground shelter here had been abandoned.

But after all these years, the power system is still working normally, which is definitely a great miracle.

Because the electrical equipment in the corridor is turned on by default, as long as the main switch is turned on, these equipment will automatically work.

"There are so many lights, but none of them has a problem... What kind of quality is this?"

There is nothing wrong with the performance of these devices other than the fact that the devices are a bit dated.

At this time, Xu You walked to the side of the elevator.

Through the judgment of various written information, Xu You can already confirm that the entire underground shelter really only has six floors.

And the numbering of the floors here is not according to the rules of Lanxing's side. The topmost floor is the basement floor, and then they are arranged in order.

Instead, the top is six layers, and the bottom is one layer.

Such an arrangement may be because there are no buildings on the moon.

"The elevator on the first floor can continue to go down... It seems that there is really a hole in the bottom. But why, the stairs can't go down after reaching the first floor?"

With such doubts, Xu You couldn't help pressing the down button.

As Xu You's finger touched the button, the down button immediately lit up, and at the same time, there was the sound of the elevator running.

Perhaps it was because the elevator had not been maintained for a long time, and the elevator was running with a loud friction sound, which made Xu You a little worried that the elevator would break down.
