Chapter 670 Why are there only six floors?
At this time, even if the elevator could really operate, 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, there will be 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 road below.
"Only six floors? If that's the case, the number of people that the entire moon can accommodate is..."
At this time, Xu You's brain was working 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 to the Blue Star, the Moon is a smaller planet. Its diameter is only three-elevenths of the Blue Star, and its surface area is only about one-fourteenth of the Blue Star.
If we think in this direction, if we want to accommodate enough people, the more floors of these underground shelters the better.
But in fact, on the blue planet, land only accounts for about 29% of the total area of the blue planet, and most of the area of the blue planet is covered by oceans.
And of that land area, only a small amount is used for living.
If you think about it this way, if most of the underground area of the moon is used as shelter, it can accommodate a large population.
Even if all eight billion people on the blue planet lived in it, there would still be enough space.
only……
"Does this mean that this underground shelter has no other functions besides living in it?"
If it is a space station in the conventional sense, astronauts only need to stay in it for a few months, so naturally there will not be too much space reserved.
But if it comes to interstellar travel, it is impossible for people to stay in the room all the time, and there must be various other facilities.
The time required for interstellar travel may be more than hundreds of years, and humans may even have been able to reproduce 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 signs of development on the moon's surface, there must be some other caves inside the moon..."
Thinking of this, Xu You continued his exploration of the underground shelter.
At this time, Xu You's oxygen and energy had been consumed to a certain extent, but Xu You had no way to retreat.
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.
"I really can't keep my promise to be back in half an hour. If there is any way to get in touch with the outside world, it will also make Yaoyao feel more at ease."
As Xu You thought, he explored forward in a certain order and memorized the surrounding environment in his brain.
Xu You's brain is very powerful. He can draw all the places he has been to in three-dimensional form on the map in his mind, as if he had his own high-precision map software.
Soon, Xu You understood the structure of the underground shelter in more detail.
Xu You found traces of several essential systems for underground shelters, including air ducts, drainage systems, circulation systems, and power systems.
After discovering a large number of texts, Xu You gradually translated the possible meanings of some of the texts.
In his spare time, Xu You once studied how to translate an unknown language.
Theoretically, as long as there are enough samples, a high translation accuracy can be achieved even when facing a completely unfamiliar language.
"If my guess is correct, this is the power 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 electricity at all?"
After listing several possible reasons, Xu You turned the power switch back to what he thought was the open position and continued exploring forward.
After walking for a while, Xu You got more information about the underground shelter.
The entire underground here is used for living, with no open space, roads or other facilities.
Each of these shelters also has its own number, similar to the communities, neighborhoods, buildings, units, etc. on the Blue Planet.
Xu You knew that if the main switch of the circuit breaker was not turned on, it would not make much sense to only control some switches that were responsible for small parts.
"Hmm? Is the switch here turned off?"
At this time, Xu You discovered a main switch that seemed to control the entire "community".
With the information he just obtained, Xu You can basically confirm that the symbol pointed by this switch should be off.
With a hint of excitement, Xu You pushed the switch up.
In an instant, a buzzing sound was heard throughout the entire underground shelter.
Then, the lights in the corridor lit up one after another.
"The power... is on?"
Seeing this scene, Xu You couldn't help but be surprised.
Xu You didn't know how long the underground shelter 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 switch is turned on, these devices will start working automatically.
"There are so many lights, but not a single one has a problem... What kind of quality is this?"
Apart from the fact that the equipment appears a little old, there is no problem with the performance of these devices.
At this
By judging various text messages, Xu You has been able to confirm that the entire underground shelter does have only six floors.
The floor numbering here does not follow the rules on Blue Star. The top floor is the underground floor, and the floors are numbered downwards in sequence.
Instead, the top one has six layers, and the bottom one has only one layer.
This arrangement may be because there are no buildings on the moon.
"The elevator on the first floor can actually go down further... It seems that there is really another world below. But why can't the stairs go down any further 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 down button immediately lit up, and 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 noise when running, which made Xu You a little worried that the elevator would malfunction.
