After handing in their sabers, daggers, Gaussian pistols and magazines, the three captains were led to a building similar to a train station, where there were multiple security lanes, but because it was late at night, only one security channel was still in operation in the hall.

"If you have metal objects, please put them in this box."

There was only one security lane, but there were not many people at all, and five or six heavily armed soldiers were stationed nearby, one of whom handed them an iron box to the crowd.

The captain took the iron box, but there were no metal products on him, and then Xiao Jiang took out a mobile phone, and Lao Ding took out two metal "lighters" and threw them in, and then handed them back to the soldier.

Naturally, it is impossible for the three captains to completely disarm all their bodies, but the floating cannon can be hidden from being discovered, and the lighter in Lao Ding's hand is not visible from the black technology of Base 49 in terms of these security, only the mobile phone that Xiao Jiang took out made the soldier look at it twice...... In these years, even Nokia's artifact can't connect to the signal anymore, and for the first time, I saw someone with a mobile phone.

However, the soldier didn't think much about it, anyway, Xiao Jiang was holding a smartphone, and it was the same when he used it as a game console, but there were fewer and fewer people who could repair mobile phones.

After the security channel, the three captains naturally passed easily, and the alarm never sounded once, which was also due to the fact that the captain put all the valuable and sensitive items on the car, the car was produced by the No. 49 base, and the anti-theft measures inside were definitely safer than taking them with them. Therefore, except for Xiao Jiang carrying a small bag containing a few bottles of mineral water and energy bars, the three captains did not bring anything else.

"Your stuff ......"

After passing through the security checkpoint, another soldier placed the box on the table and asked the three to take their belongings. Then, the soldier sitting at the table smiled at the three of them and said, "Welcome to Vault A-011, by the way, a word of caution, if you want to stay, please go down to the lower floor, you can find a cheaper hotel on the second or third floor." ”

"Oh, thanks for the reminder." The three captains also smiled back, which was ...... It's as good as before the end of the world.

After passing through the security check, and continuing a little further on, there is a large number of elevators, yes, the kind of escalators in the mall, and there are the same number of wide stairs next to them, apparently to prevent power outages.

The three captains took Xiao An, no, they were holding Xiao An, standing on the escalator, and slowly descending with the escalator, giving people a feeling of taking the subway, but the subway station of this scale is afraid that it cannot be found in the world, because this is a large shelter built for hundreds of thousands of people to evacuate.

It wasn't until they left the escalator that the three captains really got a full view of the shelter......

Vault A-011 was the territory of the Great Wall of Steel three years ago, and as one of the few A-class shelters in the hands of the Great Wall of Steel, especially Vault A-011 is still a large shelter, so the investment of the Great Wall of Steel here is not ordinary.

As far as the eye can see, it is late at night, but there are still neat street lights, spacious streets, and rows of shops...... Although most of the shops are still closed, it is still a sign of the prosperity of the place...... These shops were not built by the Great Wall of Steel, but were designed from the beginning of the Vault, because the original large Shelter was basically designed to allow more humans to live in it for a long time, so a certain degree of recreational facilities and commodity exchange were absolutely necessary.

As a result, shops are usually built on the first floor of these large shelters.

Looking up at the ceiling, the three captains had been sitting on the escalator for more than ten minutes, and it was naturally quite far from the ground. The ceiling alone is at least a dozen meters high, and if all the headlights on the ceiling are turned on during the day, then it is no different from the daytime, and now that the southern part of Middle-earth has become a desert, as long as the solar panels that come with the shelter are released to charge, it only takes a few hours to fill the power reserve of the entire shelter, and there is no need to worry about being squandered.

In fact, the three captains were already able to feel the luxury here. As soon as they entered the shelter, they felt the cool air conditioning, there is a 24-hour intelligent central air conditioning, and there is a state-of-the-art ventilation system, if you don't think about food and other problems, you will not have any problems surviving here for the rest of your life.

As soon as he entered the shelter, Lao Ding couldn't wait to take out the map from his pocket, and after careful comparison, Lao Ding finally showed a smile and said: "It can be determined that Vault A-011 is the XXX shelter before the apocalypse, and the standard for the construction of this shelter is to survive for more than 20 years within the standard of 200,000 residents, or more than 10 years for the maximum of 500,000 residents, and if you don't consider the long-term survival problem, it can even accommodate a million people." ”

"The total area of this shelter is tens of millions of square meters, and it is divided into five floors, each of which has an area of millions of square meters, and the bottom layer should also have a micro-ecosystem for the production of food, but I don't know if the current micro-biosphere is complete and how much food can be produced."

The captain nodded and said, "There is no need to elaborate on these things, we will rest here for a day or two, and set off immediately after determining the target location." ”

"Yes, Captain." Lao Ding replied.

The three of them walked down the street, looking at the road signs erected near the street, looking for directions to the lower level, the soldier at the security check said that they could find a good hotel on the second and third floors, and now what they needed most was a good place to stay.

The only thing that is not clear is what the prices are in this shelter...... Although the things in Xiao Jiang's bag can be said to be priceless in the oasis outside, those who are a little weaker will be killed and oversold.

However, after seeing that the shelter was so well preserved and orderly, the three captains were a little unsure if the supplies would be enough for their consumption in the past two days. After all, high enjoyment means high consumption, and the average waste picker may not even be able to pay the entrance fee to this refuge.

And as for whether there is currency here...... The three of them are not too sure, except for the fact that the scientific research city has now completely replaced currency with credits, the post-apocalyptic world has basically degenerated to the primitive economy of barter, after all, nuclear cola is not popular here, and there are not so many bottle caps to exchange.
