"You can get out of the cabin, please be sure to pay attention to safety." Jiang Ping, the leader of the operation team, instructed everyone.

When he got here, even if Liu Yi was the commander-in-chief, he had to listen to Jiang Ping's arrangement, and no one was more experienced in space operations than him.

Jiang Ping was the first to walk out of the hatch, and the others followed behind and walked out of the hatch in turn, and when everyone stood on the surface of the big cylinder, Jiang Ping led everyone to the maintenance port.

Opening the thick cover of the maintenance opening, a dark and deep passage appeared in front of him, Jiang Ping turned on the searchlight on his helmet and took the lead in getting in, and the others followed his example and entered one by one.

The passage is very deep, but fortunately this is in a gravity-free environment, so you just need to control your body and float forward slowly. Otherwise, with such a long passage, just crawling can tire everyone half to death.

Finally, the narrow passage came to an end, and a metal door with a rotating valve appeared in front of it, and at this time Jiang Ping told everyone: "Please hold on to the things that you can grasp around you, once this door is opened, a strong air flow will blow out." ”

Everyone hurriedly grabbed the handrails and pipes around them, and then said, "Okay, okay...... It's time to open the door! ”

Jiang Ping nodded, buckled the strap on his waist to the armrest beside him, and then began to rotate the valve on the metal door.

The metal door suddenly opened suddenly, and a strong air current rushed out, blowing everyone sideways at once, and if it wasn't for the things around them that had been tightly grasped beforehand, they would definitely be blown out of the passage by the air current.

Fortunately, this powerful air flow only lasted for a few seconds, and when everything calmed down, Jiang Ping said, "You can go in." ”

Everyone entered the metal door, Jiang Ping closed the heavy metal door, retightened the valve, and then said: "This is a closed air chamber, and the next step is to start supplementing oxygen." ”

After speaking, Jiang Ping came to a console, stretched out his hand to open the cover of the console, and a red indicator light lit up in the dark.

Jiang Ping pressed twice on the console, and then he heard a noise from the air current, and after about a minute or two, the red indicator light on the console went out, and a green indicator light lit up.

"Now I can breathe, even if I take off my helmet." Jiang Ping said and pressed it again on the console, and the lights around him suddenly turned on.

"It turned out to be a ventilation chamber." Someone said.

"That's right, the previous passage was actually the outer shell, and if you continue from here, you should enter the base part that supports the outer shell." Jiang Ping said.

Due to the experience of many maintenance and construction accumulated in the past, Jiang Ping expressed his judgment.

Tang Jie took off his helmet and asked, "Where did you go deepest before?" ”

Jiang Ping replied: "A little further from here, we don't dare to go too deep, for fear of causing trouble." ”

Liu Yi carefully observed the surroundings, and judging by the degree of wear and tear of various things, this huge building was not put into use at all, and may have been abandoned before the construction was completed.

"Let's go, the oxygen level is completely fine now." Jiang Ping said.

Coming to the hatch, Jiang Ping pressed a few times on the operation panel next to the door, the door of the ventilation cabin slowly opened, and everyone followed him out of the ventilation cabin and into a narrow passage.

From both sides of the passage, you can see the massive metal structures connected to each other, like the skeletons of giants.

In the gaps between these huge components, there are a large number of complex mechanical devices, as well as various pipes that are densely packed like blood vessels, and everyone has the feeling of burrowing into the belly of a giant.

The long and narrow maintenance passage is like a maze, and everyone is entering it for the first time, so they dare not run around casually, so they must stop at every fork in the road and take a closer look at the signs next to it, so as not to get lost in this very complicated place.

The group carefully followed the instructions of the signs, and at the same time kept an eye out for changes in air quality, as well as changes in the radiation index.

Finally, everyone finally passed through the base layer and came to the facility floor where various instruments and equipment were placed, as well as a large number of pipelines.

What you see here are all kinds of mechanical equipment, electronic instruments, and a large number of wires and conduits, which make people dazzled and don't know where they are.

Liu Yi soon felt dizzy and couldn't tell the direction at all, but at this time, Tang Jie was extremely conscious, and she deduced her current position while distinguishing the various equipment around her.

Tang Jie analyzed the possible position of everyone at present, and then led everyone to find the way to the interior according to her inference.

"This is supposed to be a place to treat water, and if we follow these pipes, we should be able to find a way to the inside." Tang Jie analyzed.

One of Mei Yuqi's subordinates said: "In our Tuoyuanxing, we are used to using red water pipes to transport drinking water, we can first find out if there is a red water pipe, and then follow it." ”

"Oh, that's your habit." Liu Yi said: "Everyone spread out and look for it!" ”

So, the people divided up to search the place full of large jars, and soon someone found the thick red water pipe, so they told everyone to assemble in that place.

Everyone rushed there to see that there were a lot of red water pipes, so everyone walked along the water pipes. After walking for a long time, I finally found an inconspicuous small door in a very secret place.

Someone was just about to push the door, but Jiang Ping stopped him violently: "Wait! Let me measure it before I open the door. ”

Jiang Ping came to the door, first measured the temperature, then looked at the radiation index, and finally checked the air quality index, and saw that everything was normal, Jiang Ping pushed open the small door.

It was pitch black behind the door, Jiang Ping first stuck his head out, looked at it with the help of the light of the searchlight, and walked out with confidence after seeing that there was nothing abnormal.

Everyone walked out, and it turned out that behind the door was a dark corridor, different from the maintenance passage they had walked before, this corridor looked very much like the corridor on a ship, and there were no exposed mechanical equipment and various pipelines along the way, indicating that this corridor was for people's daily use.

Tang Jie said: "This should already belong to the normal working floor, you see, except for the necessary switches and interfaces, there are no exposed equipment and pipelines on the wall. ”

Everyone nodded one after another, saying that what Tang Jie said was reasonable, this place is indeed like a daily work and living area, and it seems that everyone is one step closer to the core.

Unfortunately, none of the lighting equipment here can be used, and the indicators of various switches are all turned off, indicating that there is a lack of power supply here, and all kinds of equipment cannot be used normally.

"Strange, why is there no electricity here?" Someone can't help but ask.

Tang Jie explained with a smile: "This place has been unused for a long time, and I am afraid that the power system has already been automatically shut down due to safety needs." ”

"But it seems that there is electricity all the way just now?"

"That's different, the maintenance level maintains a certain amount of electricity, so that if there is an emergency, it can be dealt with immediately, such as preventing fires, opening automatic doors, etc." Tang Jie continued to explain.

"I see, how can the power here be restored, it can't be dark all the time, right?"

"To restore power to the working floor, we may need to activate the central control system, so let's get to the core and find the central control room." Tang Jie said.

The lack of electricity prevented the automatic doors in many places and left them looking for safe passages that could be opened without electricity.

Fortunately, everyone is wearing powered work clothes, and it is also in a gravity-free environment, so many places can be easily passed up and down, otherwise the road will be very hard.

In the end, it was because the place was so big and there was no necessary instruction that people often had to run back and forth many times to find the right way.

Before I knew it, several hours had passed, and at this time the group was tired and out of breath, so Liu Yi saw this and ordered to rest temporarily, and continue to search when his strength was restored.

Everyone stopped on the spot, took out the energy potion to replenish physical strength, and poured it into their stomachs with their necks tilted. This energy potion can quickly restore physical strength, and is a common portable potion in the army.

As the power of the medicine took effect, everyone returned to a state full of energy, and Liu Yi saw that the time was almost up, so he ordered to continue to find a way forward.

At this point, everyone had forgotten how many corridors they had passed through and how many security doors they had passed through, but everyone had a clear feeling that they were not far from the core.

Another security door was opened, and an unusually cold air rushed in front of them, freezing everyone to the point of stiffness.

"Whew! It's so cold, why is it so cold here? ”

Liu Yi keenly sensed that there seemed to be something unusual behind this security door, he raised the searchlight and shone it into the door, only to find that the light seemed to be swallowed up by darkness, and he couldn't see anything.

"It's so deep! And the temperature of the air is so low, I'm afraid there is a lot of space inside the door......" Liu Yi guessed.

At this time, Jiang Ping rushed to Liu Yi's side and said, "Sir, let me go first." ”

Liu Yi nodded, put his body aside, Jiang Ping jumped forward next to Liu Yi, and floated towards the door.

After Jiang Ping entered, he was quickly drowned in deep darkness, Liu Yi was a little worried in his heart, and hurriedly shouted: "Jiang Ping! What's inside? ”

Only then did Liu Yi realize that the echo behind the door was very loud, wave after wave, and it seemed that the inside was wide and empty.

After a while, Jiang Ping's voice came slowly: "Sir, this place is very big, it seems to be a very big warehouse!" ”

Liu Yi listened to Jiang Ping's words, beckoned to everyone and said, "Let's go, let's go in and have a look!" ”

After speaking, Liu Yi took the lead and floated in, and the surroundings were much darker, and he felt that he was completely wrapped in thick darkness.
