The deep tunnel is full of giant vines, and the sunlight does not shine here, so the whole tunnel looks extremely dark.

Ye Chen pulled out the melee fighter, he was not afraid of the technological traps in the tunnel, close to a century of mechanisms, if he needed to rely on electricity, it was also a question whether he could activate it, only some artificial traps would attract his attention.

Under Ye Chen's infrared vision, the fluctuations containing heat and even high energy can't hide from his eyes, and if the mechanism here is still electrified, it naturally can't hide from her eyes.

The tunnel is not very long, and at the end of the tunnel is a metal gate, which should be the only place around where you can live.

Now covered in moss, but with no signs of rust in sight, the metal gate is a digitally locked gate made of steel that may not be able to break through even if it is bombarded with miniature grenades.

Ye Chen just glanced at it, and he was able to determine that the interior would not be a military base, nor could it be a secret research institute, but rather a base for refugees.

The asylum base, which is used to protect against intercontinental missiles or even nuclear bombs, can have little impact as long as it is not a frontal impact.

The evacuee base has its own independent processing system, and even a nuclear reactor to meet the needs of self-consumption, but at present, the digital gate has long been without light prompts, and even the buttons have been completely corrupted, and it is obvious that the power has been cut off for a long time.

This secret base should have been reserved for the use of the big men of the old era, but for some reason, it was built until now, and it has obviously not really been used, and now it has become an abandoned thing in the abandoned land.

Originally, the method of opening the door was very simple, only a few digits of the digital password, plus the possible retinal scan, now, the method of opening the door is also very simple, open it violently, think about it There is no other way.

Ye Chen used the melee to scrape off the moss on the steel gate, through the light, he could see some words, but many of them were blurred, Ye Chen barely understood some, this gate was built by the old era of Huaguo, established in the last tenth year of the old era, up to now, it has been more than a century, and it records the method of opening, the password, and some precautions.

If a password is entered successfully, it will trigger the defense mechanism, as for what the defense mechanism will be, Ye Chen doesn't care, he only knows that he may be happy in vain.

This gate is made of mixed steel, and the steel interlayer will be at least a few centimeters thick, not to mention carrying miniature grenades, even the shells of heavy armored vehicles may not be able to break with a single shot.

Since it is a hidden base used to evade nuclear bombs, its defensive measures are naturally the most perfect, otherwise the aftermath of the nuclear bomb from the outside world will not be able to break through easily.

However, a mountain is a mountain after all, even if it is impermeable in all aspects, it also has its weak points, such as the ventilation and sewage pipes, although they will be treated, but these two places must be the weakest, and they can be exploded with miniature grenades.

However, these two places are extremely secretive, if you are unlucky, it may be built under the mountain, that is to say, Ye Chen has to dig at least a precise pit dozens of meters deep, don't look at the mountains here are not high, but the rocks are extremely hard, if you dig manually, even if Ye Chen spends several years, there will be no results.

Ye Chen could only pray that his luck would not be so bad, hoping that the engineers and planners who built this base in the first place would be lazy and not build vents and sewage pipes under the mountain.

The next thing is very boring, because there may be hidden vents anywhere in the mountain, and the vents will only be opened when the machine is running, which is extremely troublesome to find, and the corresponding sewage pipes will be easier to find, and the outlet should be near the surrounding streams, but the sewage pipes may not be able to accommodate Ye Chen's body.

Ye Chen spent most of the day, I don't know how many traces he made on the mountain, and finally found the sewage pipe near a stream, and coincidentally, the vent was built near the sewage pipe, which was obviously intentional.

I don't know if it was cutting corners, or if the aftermath of the nuclear bomb opened the bunker, and the sewage pipe was directly exposed to Ye Chen's sight, where was there a little hidden effect.

As Ye Chen thought, the outermost part of the sewage pipe was just a hole to accommodate the sphere, even if he used a miniature grenade to blow it up, he might not get the effect he wanted, and the vent was different, the huge vent was still protected by a cover, but the small part exposed was half as high as Ye Chen.

The huge steel fan had long since stopped running, because the bunker was destroyed, the air had already circulated inside, the fan and the passage were covered with green moss, Ye Chen used the melee to split the barbed wire at the entrance of the passage, and stepped in.

The passage is deep, more than two meters high, and this is the ultimate source of vents, which get narrower and narrower if you can't find the main control room once you go inside.

Through the light, Ye Chen could feel the appearance of the old era building, there were no small creatures here, and the entire base had been closed for a century, waiting for Ye Chen to open it.

The center where all the vents are connected, Ye Chen, with his understanding of the survivor base, roughly analyzed the internal structure of this base, different from the K1 base, etc., in the old era, the K1 base was a small military base, and this hidden base, but the refuge base, the internal structure is more complex, which means that it is more suitable for people to live in.

Ye Chen didn't know how long he had been groping, even Ye Chen, who had never been afraid of physical exertion, was a little tired, and his pants had worn out after a long time of kneeling and crawling, but fortunately, Ye Chen, who had been strengthened by the flesh, had much more useful skin than these pants.

When the day was completely darkened, Ye Chen finally found the entry point, here is the vent above the main control room, with a few knives down, Ye Chen landed perfectly in the main control room, although he did not understand the machine control, but turned on the switch, and a series of Chinese prompts, he still understood.

After Ye Chen pressed the red button on the main control console, the originally silent base emitted a series of sounds, first of all, the various lights connected to the base were turned on one after another, accompanied by the rotating red light above the main control room, the entire base began to operate, it was obvious that this hidden base had its own system, and it was not affected by the nuclear bomb.

After a series of operations, Ye Chen heard the voice of the artificial intelligence, "The base authorization system is initialized, please reconfirm the permissions of the administrator." ”

"Ye Chen!" Although Ye Chen was a little surprised, he still quickly said his name, this base was reserved for the use of the big people in the old era, after it was built, the authorization system of the base was adjusted, that is to say, from now on, Ye Chen will be the only owner of this base.

Although the entire base is all built in the mountains, the space is extremely large, and it can accommodate at least a hundred people, but this base was originally only reserved for a few big people and their immediate family members, that is to say, the food and other supplies inside have clear indicators, for Ye Chen, this is simply a waste.

All the iron gates in the base have face recognition and voice recognition devices, and after Ye Chen set up a list of programs, he held the map of the base in his hand and wanted to take a look around.

This base has no name, and now it has become Ye Chen's personal belongings, so he has to name it after his surname, calling it Y1 base, although it is not good, but it has symbolic meaning.

Out of the main control room, what greeted him was the living room of the base, which was like a large version of a football field, with many items that Ye Chen had never seen before, which should be the product of the old era, and it was necessary for him to spend a while to make up for the knowledge of the old era.

Next to the living room, there is a storage cabinet, like a small attic, most of the storage is living utensils, there is very little food, food is such a thing, no matter how well it is preserved, it also has its shelf life, so it is impossible to store a large number of them.

The living room is like the center of the whole base, and the main control room is the core, and all the rooms are connected to the living room, from the storage cabinet to the bedroom.

However, this is different from the family house, which also has a garage, a medical room, a biochemical laboratory, and even a golf course on a large area.

And this base has three floors, Ye Chen's current location belongs to the ground floor, and there are two underground floors, the basement floor has various equipment and facilities, ammunition depots, reclaimed water treatment stations, and air purification stations, and even a small automatic factory, and there is a storage room next to it, all of which are small parts.

The most important and core is the second basement floor, which has an artificially built nuclear reactor supply, which is connected to all the equipment on the basement floor, and the equipment on the ground floor is connected to the basement floor.

This nuclear reactor is no longer considered small, even if the entire base is fully operational, it can be maintained for at least a hundred years, and the descendants of the big people who live here can completely escape the pollution of nuclear radiation and re-establish the city on the ground after a hundred years.

However, the old era was able to maintain nuclear radiation for a hundred years, and in the new era, it can be maintained for hundreds of years, thanks to the genetic weapons left behind by the monster, which blended with nuclear pollution, and seemed to take root in the stars and exist here forever.

Ye Chen doesn't understand the operation of these devices, and he doesn't need to understand it, everything here is automated, and there are artificial intelligence services at all times, and the computers inside the base record countless information from the old era, and even have private satellites, but they are turned off for a long time, and rebooting requires code, and Ye Chen doesn't understand that at all.
