"No, there is no way to get in touch with the outside world at all."

Xu You tried many ways to get in touch with the outside world, but finally shook his head helplessly.

After his feet began to vibrate, Xu You also immediately realized that he had lost the signal connection with the outside world.

It stands to reason that in such a situation, Xu You needs to return immediately.

However, what made Xu You feel even more unbelievable was that his way back was actually blocked by a mysterious force.

"This kind of mechanism seems to appear in a suspense novel. I don't understand the mechanism at all." Xu You said to himself.

After seeing that the road he just walked was completely blocked, Xu You couldn't figure out how to achieve this.

Even Xu You doubted whether he was in a dream.

But at this time, Xu You didn't have any fear in his heart, he just knew that Lu Zhiyao would be very worried about him.

"I don't know what's going on at the top... Hey, there's no way to get in touch with the top."

Just when Xu You was thinking about this, he suddenly discovered that there seemed to be a new passage not far ahead.

"Anyway, the way back is blocked, so let's move on."

Xu You didn't care about so much, took a deep breath, and continued to walk forward.

According to the remaining power of the Gopher, it cannot accompany Xu You for too long, but fortunately, Xu You carries enough oxygen. If it is used normally, it will not have any problem supporting it for ten hours.

With curiosity and anticipation, Xu You continued to walk forward.

"Um?"

When Xu You approached, 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 enough for one person to enter.

"This is... a climbing ladder?"

Xu You shone the light under the entrance of the cave, and was surprised to find that there was no longer a bare rock wall inside the cave this time, but something like a climbing ladder appeared, and one could lie down along the ladder.

Without too much hesitation, Xu You stretched his legs down one by one, stepped on the ladder, and climbed down bit by bit.

After climbing dozens of stairs like this, Xu You suddenly found that his feet were on the ground.

"In the end?"

Xu You illuminated the surroundings with lights, and gradually saw the surrounding layout clearly.

"Here...the place is actually not small!"

Under the illumination of the light, the picture in front of Xu You's eyes finally became clear.

The space here is far wider than imagined, which makes Xu You feel suddenly enlightened.

This is an interior structure similar to a living room. Although the room looks a bit old after the baptism of time, it can be seen that the previous decoration here should be good.

The doors connected to the living room are respectively connected to rooms such as the bedroom, kitchen, bathroom and so on.

"Looking at the size design of the room, the former occupants should be about the same size as a human being. Even if I live here, it should be more suitable for living."

At this moment, Xu You had a feeling that perhaps the intelligent creatures that used to live here may have a very close relationship with the humans on Blue Star.

The various equipment, home appliances, furniture, etc. in the room are not consistent with those on Blue Star, but many Xu You can see what their functions are.

It was just because there was no energy supply that Xu You couldn't activate these devices.

At this time, Xu You walked to the door of the entire room and tried to open the door.

Immediately, Xu You realized that the door was not locked, and the door could be opened with a light push.

"Perhaps when they are thorough, because they have given up the facilities here, there is no need to lock them again." Xu You thought.

After coming out of the room, Xu You found that in the entire corridor, there were many similar doors, and there should be many residents living here.

The structure in each room is also different, and it can be seen that it should be related to the number and class of people living.

Many rooms here are not so complete in function. There are only the most basic bedrooms, kitchens and bathrooms, and there is not even a living room.

But if you live alone, such a room is enough.

"It looks like this is an underground refuge." Xu You said to himself.

While speaking, Xu You turned on the detection function attached to the spacesuit to search the surrounding environment.

With his own feeling, Xu You can be sure that there is air here, and the ambient temperature is much milder than that on the moon.

After some detailed testing, Xu You confirmed his thoughts.

However, the content of various gases in the air here is still quite different from that of Blue Star, which is not enough for Xu You to take off the space suit on his body.

"The oxygen content is 15 percent... If the oxygen in the oxygen tank is exhausted, you can barely breathe for a while."

With Xu You's physical fitness, the environment with low oxygen content can still be persisted, and the temperature here is also around ten degrees Celsius, which is not unbearable.

At this time, Xu You couldn't help thinking about how such an underground shelter was built, and how to produce oxygen and maintain the ambient temperature in it.

"It seems that there must be many high-tech technologies 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 widely exist underground on the moon.

Such a huge project is really a great miracle.

"Wait a minute... Maybe the helium 3 that exists on the moon is the energy that provides all this?"

It stands to reason that there is no trace of any 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 likely to be produced through controllable nuclear fusion.

At this moment, a new thought suddenly popped up in Xu You's heart.

"If we can find the switch to start these energy operations, can this underground shelter be put into operation again?"

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

The first room Xu You entered just now should be the topmost floor of the underground shelter. There are some symbols similar to words in the corridor, and Xu You can't translate them immediately.

"Huh? Is this an elevator?"

Soon, Xu You found devices like elevators, but because there was no power supply, Xu You had no choice but to continue exploring down through the stairs.
