Chapter 671 Why are there only six floors?

At this time, even if the elevator could really run, Xu You did not dare to enter the elevator easily.

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

Xu You originally thought that there would be many levels 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 the entire moon can accommodate is..."

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

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

Compared with the Blue Star, the Moon is a smaller planet. The diameter of the Moon is only three-elevenths of the Blue Star, and the surface area of ​​the Moon is only about one-fourth of the Blue Star's surface area.

If you think in this direction, if you want to accommodate enough people, the more layers these underground shelters have, the better.

But in fact, on Blue Star, land only accounts for about 29% of the total area of ​​Blue Star. Most of the area on Blue Star is covered by the ocean.

And only a small amount of that land area is 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 if all eight billion people on Blue Star live in it, this kind of space will be completely sufficient.

only……

"Does it mean that this underground shelter has no other function besides living?"

If it is a space station in a conventional sense, astronauts only need to stay there for a few months, so naturally there will not be too much space reserved.

But if it were an interstellar voyage, it would be impossible for people to just stay in their rooms all the time. Xu You would have to have various other facilities.

The time required to sail across the stars may be hundreds of years or more, and humans have even been able to pass on their clans for several generations.

However, Xu You did not find any other activity space besides the living room.

"Wait a moment……"

At this time, Xu You suddenly remembered the hypothesis that there might be holes inside the moon.

"Since there are no traces of development on the surface of the moon... then there should be holes inside 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 again.

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

As Xu You thought about it, he explored forward along a certain sequence and memorized the surrounding environment in his brain.

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

Soon, Xu You understood the structure of the underground shelter in more detail.

Xu You found traces of many systems necessary for underground shelters, including air pipes, drainage systems, circulation systems, and electrical systems.

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

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

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

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

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

Is the equipment broken? Or is there no power supply at all?”

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

After walking for a while, Xu You got more information about the underground shelter.

The entire underground here is used for residences, and there are no open spaces, roads or other facilities.

These shelters also have their own numbers, similar to the communities, residential areas, buildings, units, etc. on Blue Star.

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

"Huh? Is the electric switch here closed?"

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

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

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

In an instant, there were buzzing sounds throughout the underground shelter.

Following this, the lights in the corridor lit up one after another.

"The electricity... started?"

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

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

But after so many years, the power system can still work normally, which is definitely a great miracle.

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

"There are so many lights, but none of them have problems... What kind of quality is this?"

There is no problem with the performance of these devices except that the equipment looks a bit older.

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

By judging various written information, Xu You has been able to determine that the entire underground shelter does only have six floors.

The numbering of the floors here does not follow the rules at Blue Star. The top one is the underground floor, and then they are arranged downwards.

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

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

"The elevator on the first floor can actually continue to go down... It seems that there is really a cave below. But why can't the stairs go down again after reaching the first floor?"

With such doubts, Xu You couldn't help but press the down button with his hand.

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

Perhaps because it had not been maintained for a long time, the elevator made a loud friction sound when running, which made Xu You a little worried that the elevator would malfunction.
