Humans became extinct after returning to Earth [Infrastructure]

Luo Guiting didn't know what happened, but saw Wen Cheng's body tense and serious expression, and there was no signal when he tried to contact Luo Qi.

It wasn't until Luo Guiting was restless underwater that he saw Luo Qi's reply saying that the signal interception was successful.

There is no need to explain further, there should be a signal sent out the moment the submarine was turned on just now.However, the three of them were not completely unprepared, they had installed signal interception devices.

It's just that it's uncertain whether this signal interception device can completely intercept it, because they know very little about this submarine.

Now Luo Qi has given a reply, that is 100% no problem.

Wen Cheng relaxed, and Luo Guiting heaved a sigh of relief.

Immediately after Wencheng continued to operate the machine, Luo Guiting felt the change in the surrounding water pressure, and the submarine finally heard the roar of the machine starting up, and then saw Wencheng swim a little backward, and Luo Guiting hurriedly followed.

After waiting for a few more minutes, a door was opened at a place where the eyes were closed so tightly that it could not be seen as a door at all.

It is in the shape of a half-moon door, and if you look closely, it should only be half-opened.

Wen Cheng pulled Luo Guiting, and Luo Guiting dragged him into the door.

The space inside the door is not large, and you can see that the surrounding area is a little dilapidated after being soaked in water for a long time, and you can also see some traces of high-end mechanization.

After a person enters, the half door behind him closes.Immediately after the lights came on, the water inside was quickly pumped out.

After the water under his feet was completely drained, Luo Guiting did not dare to breathe, so he first checked the air quality with glasses to confirm that it was non-toxic and had oxygen before taking a deep breath.

The air is very cool, and has a little industrial smell, not particularly unpleasant, but not bad either.

Wen Chengdao: "The oxygen supply system can still be used here."

"Is there any danger there?" Luo Guiting asked.

"No, but there are remains. Let's go in after the robot is packed." Wen Cheng frowned as he spoke, apparently quite resistant to such things.

It can be understood that everyone in the 45th century is considered a flower in a greenhouse, let alone the 45th century, even in the 21st century, they are well protected and raised.

On the contrary, Luo Guiting has received relevant training and can accept it with a relatively peaceful mind.

Being in awe is the best he can do.

"So, have you figured out the situation here?" In fact, Luo Guiting is most concerned about whether there are artificial wormholes.

"The situation is similar to mine at the time. The launch device has malfunctioned. Now it is necessary to check whether it has been attacked and whether it has been left with other marks."

Wencheng also sent a copy of the information to Luo Guiting's glasses.

"It's just a bit scary," Wen Cheng couldn't help nagging while inspecting, "There are more than a dozen people inside, and there is a baby among them. The self-circulation system inside has not been damaged, and the stored food and There is also a lot of water. The time of death is very similar, and some even died lying in the dormant cabin. It doesn’t seem like they were killed by someone, and the time of death is about the same. How did they die? Is it an infectious disease? Or a virus? Or poison gas..."

Luo Guiting landed on the dilapidated and cold machines around him, interrupting Wen Cheng's chatter: "Maybe it's a collective suicide."

"Suicide? Why do you want to commit suicide? Even if you dare not come up for a while, they still have enough dormant compartments. They can sleep for tens of thousands of years and find another chance. Why do you want to commit suicide?"

If Luo Guiting could explain clearly, he would be lying in it.

It's just that this sort of thing isn't uncommon.Throughout history, being locked up in an extremely closed place, even if there is no need to worry about food and drink, people are crazy.

If there are fewer people, it will be lonely, but if there are more people, it will be fine in the short term, but in the long run, a lot of interests and even ethical issues may be involved.

Still the same sentence, people will go crazy if they are claustrophobic in one place for a long time.

After waiting for a while, there may be new results from the examination of the skeleton, and there is also an update in Luo Guiting's glasses.

"Neurotoxin remains... Can't find out what kind of poison it is?" Luo Guiting raised his eyebrows.

"It's degraded, and I can't find out what it is. Maybe it's... similar to snake venom?" Wen Cheng didn't want to be sure, so he didn't say any more.

At this time, the inside was basically cleaned up, and a passage above the head was opened, and warm wind was blowing in.Even if it is warm wind, it feels slightly cool when it blows off the moisture on the body.

After drying his body half dry and no more dripping water, the door in front of him opened.

All that can be seen is a corridor, and the wind is circulating on the road.There is only a distance of three or four meters, and after walking through it, my body changes from half dry to completely dry.

Touching the wet hair, Luo Guiting couldn't help but said, "If I take a shower and walk around here, will it be dry?"

"There is a drying room. The power here is high, which is wasteful."

When we got to the front door, there was a scan to verify that neither of them was a registered person.

I don't know how Wen Cheng operated it, but the door received an internal command to open it.

This time, the door was opened twice, and the lights in front of him turned on. A circular hall appeared in front of Luo Guiting. There were rows of machines of different shapes in front of him. There were still some traces of seawater soaking and corrosion on the walls, but they were almost invisible. what water.

Stepping in, there is hot air circulating inside, and the warm heat waves can be felt on the face, and the whole body feels warmer.

Luo Guiting has never been inside a submarine, even in the 21st century, he only took a cursory tour.Not to mention this more high-tech submarine.

Wen Cheng went to a machine and operated it. After confirming that there was no danger, Luo Guiting walked around the hall to observe without disturbing his movements.

The walls don't look much like alloys, softer to the touch than metal, but harder than plastic or something.Knock twice hard, and the sound makes people unable to distinguish the material.

Just turning around, I saw a door next to it, and when I was about to take a closer look, a pop-up window appeared in front of me.

"Grant access control rights, whether to match now."

Luo Guiting glanced at Wen Cheng, Wen Cheng nodded, and Luo Guiting immediately agreed.

"The power system seems to be a violent impact, and then the leaked fuel and parts corroded by seawater are more difficult to repair, but I can remove the parts of my previous submarine and repair it. It's just strange what kind of impact there is. Destructive power, if there is no sign of explosion, if it is just a simple impact, the strength of this submarine should not be affected."

Luo Guiting walked over to take a look, and thought about the impact: "Could it be a falling aircraft?"

"If it was an impact like an aircraft, it would definitely explode." Wen Cheng frowned.

"What if it's a meteorite, or a volcanic rock?" Although the probability is very low, but it will not explode and has great destructive power, it seems that meteorites are the most suitable.

"It is possible. If it was 500 years ago, when there were many people on the earth, all meteorites that would land would be destroyed directly after entering the atmosphere. But after the people left, no one would operate such protective devices. This submarine probably 20 years after the catastrophe... I still don't understand why they died. If it were me, even if I wanted to die, I would go outside to die, and I would rather be eaten by small fish than stay here."

Hearing these words was inexplicably familiar, as if Luo Qi's electronic voice had said similar words.

"If I can go out after being chopped up, I will send me out in pieces." It seems to be so.

Although Wen Cheng's nagging was unbearable, it was actually not too annoying.

Wencheng passed his investigation results to Luo Qi outside.Luo Qi's message can be seen by both of them.

"I'll go in."

"Don't!" Luo Guiting sent a message first.

Wen Cheng also said: "Not for the time being. You will control the machine and come here later, and go to my submarine to get these parts. The situation here is generally good, but the power system needs to be repaired. By the way, there is still energy. There is not enough energy. It's terrible, we may use it for a long time, we must find enough energy to do it. My God, we seem to have forgotten to get the general fuel for the submarine from me, what should we do, this will not be in vain. "

Luo Guiting's veins were about to pop when he heard it, but Luo Qi was still calm.

"You can use my escape pod energy."

Wen Cheng's eyes lit up: "Yeah, why did I forget? Your escape pod can be used for a long time... But is your escape pod useless?"

Luo Qi said: "Use a submarine to charge, there are artificial wormholes."

"Why did I forget? By the way, I think I can give you a surprise." Wen Cheng said deliberately.

Luo Qi sent a voice directly, his eyes were bright: "Is there an artificial wormhole?"

Luo Guiting was also taken aback, but didn't tell him first.

"Yes, but the failure is a bit serious. I think it's because of the lack of repair parts that people here can't leave through this. But we have, and the repair should be very fast. I can go to your escape pod to take a look. There is really It’s so cute, it’s small everywhere, I still want to know what it’s like in the deep underground, I haven’t been to such a deep place…”

"Then fix it, fix this first. With this, even if we are in danger, we can hide there at any time, and we just need to cut off the contact at that time."

"I don't want it." Luo Qi was quite straightforward.

Luo Guiting remembered Luo Qi's deep hatred for that place, and comforted him: "That is the most extreme environment. We will find more artificial wormholes after we reach the mainland. It's just that there is a danger in the early stage. And if you don't go in, you won't be there anymore." Come out, we can control the robot outside to find other artificial wormholes, and after we find it, we can repair it and then we can come out. If I were in that place with you, would you still be afraid?"

Luo Qi looked at Luo Guiting and still didn't respond positively.

But if there really was such an extreme day, even if Luo Qi hated him, Luo Guiting would not let him die easily.

The priority now is to repair the submarine.Luo Guiting has already obtained the access control here, and Wencheng designed and repaired it there. Luo Guiting's glasses have been shared with Luo Qi, and they began to see what's going on inside the submarine.

This place is the main control room.I walked to a door and stood there for two seconds, and the door opened automatically. There was a two-meter corridor in front of me. When I walked there, I faced a place like a movie theater. At the end was a screen. There was a stage in front, and it was empty below. , but as soon as Luo Guiting walked in, he asked whether to activate the seat.

After clicking OK, a circular hole was opened in the middle of the ground, and then a clean off-white chair was seen rising up.

Luo Guiting sat on it, feeling extremely comfortable, squinting his eyes slightly, and saw an operation page projected beside the chair:

"Please choose to watch the project. Due to the failure of the main energy source, immersive viewing is not supported for the time being. You can choose the robot performance, please understand."
