That night, when the factory area became quiet, Qi Qing and Mo Xun quietly left the yard.

Du Ruying knew that they must be going to see the air-raid shelter, and told them the general direction of entry in advance. In fact, there was only one road from the nearest evacuation entrance. Follow the road to the end, and there are clear instructions marked on the wall.

Follow the signs and you will reach a large space.

She had only been to that large space when she participated in the exercise. She remembered that she could receive supplies there, wash her hands and use the toilet, and there were signs marking where she could not enter. Other than that, there was nothing special about it.

Qi Qing asked her mother to stay at home and not follow him for the time being. If Lao Xu came to inspect at night, or if someone else came to see him for something, her mother could still handle it.

The lock at the entrance and exit was easy to open. Mo Xun took a lockpicking tool and easily did it. It was a chain lock. When they entered the door, they could wrap the chain back again, pretending that the chain was still locked. Mo Xun

My lock-picking skills are very good, and the unlocked lock can still be used as usual, so you don't have to worry about breaking it.

After entering this evacuation passage, it was just as my mother said. It was just one road, with a downward slope and no other forks. When I reached the end, I merged into a wider passage. I went down several stairs and followed the signs. It didn’t take long.

Far away, you enter a large space.

Qi Qing and Mo Xun not only brought strong flashlights, but also a detection device to roughly locate the location. Based on the layout of the factory area, they speculated that this large space did not reach the middle of the mountain, and should be just a collection under the ground of the factory area.

space.

Qi Qing felt that this place was more like an underground hall.

There is a half-meter-high stage built in front of a wall. The walls on the stage are painted white, and the ceiling above the stage still retains the curtain from many years ago. Although there are no seats under the stage at this time, everyone can stand or bring their own

Bench, it should be no problem to watch the show here.

This is the multifunctional hall of my old life.

On one side of this large space, there was a sign for the men's and women's toilets. Qi Qing went to check and found that there was no water, but the water supply must have been connected here before, and the sewage pipes were concentrated and directed to another place.

She used equipment to measure the level. This large space was ten meters deep under the ground of the military factory. There could be water supply and drainage here, and it must also have sewage pipelines. They would also need to consider sewage drainage when renovating their basement in the future.

Problem, it's best to connect it to this sewage pipe.

They wandered around this large space and found a path to other spaces.

There are indeed several other doors here, two of which are marked as equipment rooms, and non-staff members are prohibited from entering. There is also one that looks like other evacuation exits. We actually use detection equipment to scan through it to determine what is behind this door.

The tunnel leads towards the center of the mountain.

Qi Qing decided to explore the road to the mountainside first.

Mo Xun checked whether the door here had electronic control equipment, and after confirming that it was just an ordinary door, he unlocked it. There were several forked roads and iron fences behind this door, and military important area prohibitions were hung on the iron fences.

Entry sign.

They tried all the roads and found that behind several iron fences were warehouses of various materials. Except for a few tables, chairs and benches, most of them were empty.

The only thing that was different was the extremely thick iron door, which made the place feel more technological. There was an indicator light on the door, and there was a hidden keyboard.

Mo Xun reminded: "This device is a satellite patrol signal lock. It is estimated that behind this door is the military's former secret research and development base."

Qi Qing asked: "Can't you break this kind of lock?"

Mo Xun shook his head: "I have only heard of this kind of device before. Only a specific card or password can be opened. It is different from the electronic access control principle we commonly use now. Domestic satellites flying in the sky can monitor this place. Once the lock is opened,

A record will be generated and uploaded, which can easily trigger an alarm."

Since the security was so tight, how did Lao Xu get in? At that time, Lao Xu was probably only a half-grown child and would definitely not know how to open this door. Maybe there was another way, or the door was not locked at the beginning.

"Forget it, the space we are exploring today is large enough. We probably won't need it during the extreme cold natural disaster. When it gets extremely hot, it will be enough for us to move to that big space."

Mo Xun nodded, looked around again, and on the way back, he suddenly said: "I felt a little strange just now, and then I checked the rust marks and dust elsewhere, and now I can basically confirm that there might have been something there before.

It's an ordinary door. It was probably rebuilt in the past 20 years and installed with a door with a high level of protection."

Qi Qing said strangely: "The military factory was declassified twenty years ago. Besides, when we chatted with Lao Xu tonight, we never heard him say that there were any major projects here. If any facilities and equipment were added to the air-raid shelter, could Lao Xu

do you know?"

Mo Xun said: "The decryption is only about the factory area. It's possible that there is still a confidential project in the middle of the mountain. Lao Xu can't say it casually. It's also possible that there is another entrance and exit in the middle of the mountain. You heard before that you can park planes, so there must be planes.

The entrance and exit for take-off and landing. From there to transport equipment into the mountain, a gate with a high level of protection can be installed without alerting people in the factory."

"Is it possible that there are still people working in that base now?" Qi Qing suddenly opened her mind, "If that's the case, if a natural disaster strikes, we will be discovered by them if we hide in the air-raid shelter, right?"

Mo Xun smiled: "Maybe, we'll see when the time comes."

"That's right. Let's rely on our own efforts first so as not to trouble the country." Qi Qing also thought about it.

When the two of them left from the evacuation entrance, locked the chain lock as they were, and walked towards their yard, they didn't expect to meet Lao Xu.

Lao Xu was carrying an emergency light and riding a 28-inch bicycle. He didn't expect that there were people wandering around outside in the middle of the night. When he stopped and took a look, he realized it was Qi Qing and Mo Xun.

Lao Xu asked: "Xiaoqing, why are you out pawing the road so late at night?"

Qi Qing's face turned red and she said shyly: "Uncle Xu, I just ate a bit too much hot pot at night and couldn't sleep, so I asked Mo Xun to accompany me for a walk."

Lao Xu smiled with a smile on his face: "Well, young people, it's good to exercise more and cultivate relationships. The air in the mountains is very good, but it's been cold recently. You'd better not stay outside for too long, be careful of catching a cold."

"Well, thank you, Uncle Xu." Qi Qing asked again, "Why are you still patrolling at night? Isn't there no one in the factory area?"

Lao Xu said: "We have developed a habit. In the past, there were a few old brothers who alternated between guarding and night patrol. Now that I am older and sleep less, I go out to patrol if there is any problem.

, you will feel at ease once you see with your own eyes that everything is fine.”

Qi Qing was curious: "What else could be wrong with this?"

"In the past, they mainly patrolled fires. After Professor Wang and his colleagues came, one day a student said that they found that someone seemed to be poaching wild animals in the forest. He heard a sound like a gunshot. Although there are special patrols with guns in the mountains.

A forest ranger, but if there is a poacher wandering into the factory area and I bump into it, I will definitely catch him."

People who poach wild animals are indeed hateful. Qi Qingxin said that if she encountered one, she couldn't just stand by and watch. She secretly admired Lao Xu's sense of responsibility and did not dare to ask about the air-raid shelter directly. She was afraid that the other party would become suspicious, so she obediently followed Mo Xun.

Got back home.

Nothing major happened in the next few days, except that the weather got really colder and colder.

Fortunately, Qi Qing focused on repairing the basement, and had long ago given up on buying broken-bridge aluminum alloy windows to reinforce the rooms on the ground. She finally finished the basement before it snowed heavily in the factory area.
