Chapter 669: Underground Shelter
"No, there is no way to get in touch with the outside world."
Xu You tried many ways to contact the outside world, but finally shook his head helplessly.
After the ground under his feet began to vibrate, Xu You immediately discovered that he had lost signal contact with the outside world.
Logically speaking, in this situation, Xu You should return immediately.
However, what made Xu You feel even more incredible was that his way back was blocked by a mysterious force.
"This kind of mechanism seems to appear in a suspense novel. I have no idea how it works." Xu You said to himself.
Looking at the road he had just walked on, which was blocked intactly, Xu You couldn't figure out how this was achieved.
Even Xu You began to doubt whether he was in a dream.
But at this time, Xu You was not afraid at all, he just knew that Lu Zhiyao must be very worried about him.
"I don't know what's going on up there... Alas, there's no way to get in touch with them."
Just as Xu You was thinking about this, he suddenly discovered that a new passage seemed to have appeared not far ahead.
"Since the way back is blocked, let's just keep moving forward."
Xu You didn't care about all that. He took a deep breath and continued walking forward.
According to the remaining battery power of the Mole, it cannot accompany Xu You for too long. Fortunately, the amount of oxygen Xu You carries is relatively sufficient. If used normally, there will be no problem in supporting it for ten hours.
With curiosity and anticipation, Xu You continued to move forward.
"Um?"
When Xu You walked closer, he found that there was a new hole in front of him.
The diameter of this hole is not big, only a little over one meter, but it is still big enough for one person to enter.
"Is this... a climbing ladder?"
Xu You shone the light towards the bottom of the cave and was surprised to find that this time there was no longer a bare rock wall inside the cave, but something like a climbing ladder, and he could crawl down along the ladder.
Without much hesitation, Xu You stretched out his legs one by one, stepped on the ladder, and climbed down little by little.
After climbing dozens of stairs, Xu You suddenly found that his feet were on the ground.
"What's the end?"
Xu You used the light to illuminate the surrounding situation and gradually saw the surrounding layout clearly.
"This place...is actually not that small!"
Under the light, the scene in front of Xu You finally became clear.
The space here is much wider than he had imagined, giving Xu You a sense of sudden enlightenment.
This is an interior structure similar to a living room. Although the room looks a bit old after being baptized by time, it can be seen that the decoration here should have been good before.
The several doors connected to the living room are connected to rooms such as the bedroom, kitchen, bathroom, etc.
"Looking at the size of the room, the previous occupants should have been about the same size as humans. Even if I live here, it should be relatively suitable for me to live here."
At this moment, Xu You had a feeling that perhaps the intelligent creatures that once lived here might have a very close relationship with the humans on the blue planet today.
The various equipment, home appliances, furniture, etc. in the room are not the same as those on Blue Star, but Xu You can tell what their functions are.
It was just because there was no energy supply that Xu You was unable to start these devices.
At this time, Xu You walked to the door of the room and tried to open it.
Then, Xu You realized that the door was not locked and could be opened with just a gentle push.
"Maybe when they completely abandon the facilities here, there will be no need to lock it anymore." Xu You thought.
After coming out of the room, Xu You discovered that there were many similar doors in the entire corridor, and there should be many residents living here.
The structure of each room is also different, which seems to be related to the number and class of people living there.
Many of the rooms here do not have all the necessary functions. They only have the most basic bedrooms, kitchens and bathrooms, and not even living rooms.
But if you live alone, this room is enough.
"It looks like this is an underground shelter." Xu You said to himself.
As he spoke, Xu You turned on the detection function of his space suit and searched the surrounding environment.
Relying on his own feeling, Xu You could be sure that there was air here and the ambient temperature was much milder than on the moon.
After some detailed testing, Xu You confirmed his idea.
However, the content of various gases in the air here is still quite different from that on the Blue Planet, and is not enough for Xu You to take off his space suit.
"The oxygen content is 15 percent... If the oxygen in the oxygen tank is used up, you can still breathe for a while."
With Xu You's physical condition, he can still endure the low-oxygen environment, and the temperature here is around ten degrees Celsius, which is not unbearable.
At this time, Xu You couldn't help but wonder how such an underground shelter was built, and how oxygen was produced and the ambient temperature was maintained.
"It seems that there must be a lot of high-tech technology inside the moon to maintain the stable operation of the entire system."
According to Xu You's conjecture, similar underground shelter structures should not only exist near here, but should be widely distributed underground on the moon.
Such a huge project is truly a great miracle.
"Wait a minute... maybe the helium-3 on the moon is the energy source for all this?"
Logically speaking, there are no traces of industry on the surface of the moon, and the energy required to start such a powerful system must be extremely huge.
These huge energies are most likely generated through controlled nuclear fusion.
At this moment, a new idea suddenly popped up in Xu You's mind.
"If we can find the switch to start the energy flow, can we get this underground shelter up and running again?"
Thinking of this, Xu You continued searching in the underground shelter.
The first room Xu You entered just now should be the top floor of the underground shelter. There are some symbols similar to words in the corridor, which Xu You cannot translate immediately.
"Hmm? Is this the elevator?"
Soon, Xu You found a device like an elevator, but because there was no electricity, Xu You had to choose to continue exploring downwards via the stairs.
