Behind the "black wall", in the dimly lit open scene, a building standing abruptly on the ground was faintly visible, and the scene itself exuded a kind of weirdness, which made Long Yun, who had just stepped into the darkness, hesitate.

The thick dark wall actually surrounded a large clearing area, and there was a building in the clearing...... What's going on?

The light of the acetylene blowtorch was very small in the extremely wide enclosed space, and the light that shot out was completely swallowed up by the darkness almost immediately, except for where Long Yun stood, the other areas were almost completely black.

Moving in places where it is difficult to see the five fingers, even if it is just standing behind the airlock, barely observing with the faint light coming in through the doorway, a chill flowing slowly in the darkness still makes people feel hairy; I don't know what else lurks in this dark and dark open space, Long Yun, who is wearing an oxygen mask, still subconsciously holds his breath, tightly gripping the handle of an AK-74 assault rifle and preparing to shoot.

Faced with the darkness oppressing from all sides, he suddenly felt that his preparations were still a little negligent.

Now that he knew that the light in the core area of the "Dead City" was extremely dim, it would have been nice to try to fix the blowtorch to his body at that time, so that he could search slowly forward with both hands on the gun, instead of holding the gun clumsily with a lamp in one hand and the other as he did now, although he himself did not know if there was any danger lurking in this extremely dark space, and whether a thin assault rifle could handle it.

From outside the airlock to the "black wall", a few short steps away, it seems to be the boundary between the world and hell. The young man who lowered his body and crouched by the door could even hear his nervous heartbeat. Although there was only darkness in front of us, there was not even a trace of strange sound. He felt more terrifying than facing any ferocious enemy.

Faced with the fear of the dark unknown, and the irrepressible curiosity, two opposing thoughts disappeared in his mind little by little, now that he had come here, Long Yun knew that he actually had no choice; As time passed, an inexplicable sense of incongruity made him even more nervous, and he hibernated on the inside of the pitch-black gate, feeling the flow of air around him. It suddenly occurred to him why this feeling of "incongruity" arose.

Near the entrance to the "Black Wall", facing the unknown dark space, how can there be a breeze here?

Thinking back carefully, when he opened the airlock just now, Long Yun remembered that he did hear the sound of "fluttering-" in the air, but now that he thought about it, the sound was not only very small, but also very short-lived, and now he stood here, and he didn't feel any breath blockage from the enclosed space.

So......

The space behind the "black wall". Unlike what he expected, it doesn't seem to be completely closed?

Before entering the core area of the "Dead City". Before coming to the black and dark wall, Long Yun's first impression was that it was completely closed.

That's why it took a lot of trouble to break down the wall and enter the "black wall".

But now, with the help of a blowtorch, he checked the chemical test strips he carried with him, which is also the special equipment provided by the "Rome General Bureau", which can reliably detect most of the toxic gases in a non-electric environment, Long Yun saw that this group of test strips with a slight difference in color did not change color, and it seemed that the air composition behind the "black wall" was the same as the outside world, and it could support human breathing.

Before, he was worried that the space inside the "black wall" had been closed for more than ten years, and the air inside would be foul, but now it seemed that he should have guessed wrong, so Long Yun tentatively took off the oxygen mask and tried to smell the air inside the airlock.

No problem, as with the dry smell outside, it is clear that the air inside and outside the black wall is connected.

Well, if you knew this was the case, you might as well find out if there are any vents!

Walked through the airlock with all his vigilance, but now found that the "black wall" was not completely sealed, and Long Yun's first thought was "Wouldn't it be easier to find a vent to enter the space"; But now that the airlock has been opened, he doesn't bother with any ventilation problems, anyway, according to his guess, since the "black wall" wants to block a mysterious power, not a biochemical substance that is easy to leak, then it doesn't matter if there is a vent or not, he has already come in anyway.

After confirming that the air could breathe, Long Yun continued to carry the acetylene blowtorch in his hand, picked up the AK-74 and slowly groped forward, and slowly walked into the huge space behind the "black wall".

Step by step towards the deeper darkness, with the light barely illuminating the way, Long Yun's pace was very slow, and at the same time he subconsciously looked left and right, but in this dim environment, he could hardly see the vista at all. As he walked, he swept left and right with a blowtorch, and he could only vaguely see the interior of the "black wall" next to him, which also glowed with a dull metallic luster, and it was obvious that the huge space was almost empty, only the heavy giant wall and the large and small entrances above.

There was nothing unusual to the left and right, so he focused his attention on the gray building that stood abruptly.

The closer he got, the clearer the outline became, and the light cast on the gray walls made him guess that it was an ordinary reinforced concrete building; Step by step, he approached the airlock behind him at a distance of dozens of meters, and Long Yun, who raised his hand to look around, found that this building was bigger than he imagined, but it was just hidden in the vast dark space just now, and it seemed a little small.

After the closed "black wall", is there another independent building?

If his observation is correct, then Long Yun feels that this should be the design of the so-called "building within a building".

The so-called "building within a building" is sometimes seen in some special industrial sites or large real rooms, and there are separate buildings inside the building that acts as an external cover, such as the fully enclosed acoustic real yàn room that measures the absolute sound intensity. This kind of design is a waste of building space, and the cost is much higher, mainly to meet the special needs of shock absorption, isolation, etc., so it is generally not rash to adopt it when it is not necessary.

As far as the eye can see, just a few meters away from the building, the house that seems to be a "building within a building" does not look very tall, about three stories long; The "black wall" that shocked Long Yun before and didn't know the function now seems to be almost built around this "building within a building", not only surrounded by all sides, but also roofed on it, completely enclosing and isolating the entire building and the surrounding area.

In this building in the middle of the building, there must have been complete ancillary facilities, at least abundant lighting, but now that the power facilities have been damaged, Long Yun, who was standing at the door, looked from afar, only to feel that the building in front of him was like an unknown giant beast crouching in the dark.

Not only that, but sure enough, the sense of consciousness has also become stronger.

Not only that, but this inexplicable feeling has been strengthened by more than a little bit!

Feeling the fluctuations of consciousness emanating from the building, he subconsciously looked back at the continuous "black wall" hidden in the darkness, and the inexplicable feeling that Long Yun felt now was obviously stronger than before the gate was opened, when he was outside the "black wall", and it was also stronger than when he stood at the gate of the airlock; In this way, this metal wall of unknown material does have a certain shielding effect, but the shielding process is too low, and in the end it still does not save the fate of the entire base?

Standing in front of the building, he didn't notice anything unusual except for consciousness induction, and he couldn't see anything from the bare side wall, so Long Yun carried a blowtorch and an assault rifle and slowly turned around along the outer wall of the building.

In the darkness, with the faint illumination of the gas lamp, he slowly looked around at the three-story building standing in the middle of the vast space, and found that this building was more like an office building with a one-story garage, but it was obvious that there were doors and no windows, or there were few windows, and-

W-What is this?!

The blowlight beam swept through a hidden side door, and although Long Yun had already taken precautions, he was still shocked.

After the initial panic, he calmed down and took a closer look, and Long Yun, who took two steps closer, was basically sure that like the traces of tragedy that could be seen everywhere in the "dead city", the dry object lying at the door of the building was a dried corpse.

Lifting the blowtorch to check the situation, I saw a body in overalls lying outside the door, because more than ten years have passed since the tragic night of the "Rome" base, and the air here and the outside world circulate to each other, under the extremely dry and rainy Central Asian climate, time has passed, and the staff who were killed here have also become dried corpses.

Although more than ten years have passed, when he carefully examines the dry and deformed face, he seems to be able to feel the horror and confusion when this person is on the verge of death, the hollow and deep-set eye sockets, as if he is still staring straight unwillingly, and Long Yun, who has seen the dried corpse more than once, can't help but get goosebumps all over his body.

To say that he was in the line of fire of the smoke of war, no matter what kind of fierce gods and evil spirits he encountered, he would not frown, but the strange scene in front of him was another feeling, which made Long Yun behind the mask a little breathless.

Probably, if these people still have souls after death, have they always been here, full of resentment and unable to get out? ……

Long Yun felt irrepressible horror and sentimentality at the thought of the inexplicable death of the "Rome" base personnel, but when he thought of the goal of this expedition, he still cheered up and gently stepped over the dried corpses lying on the ground, and approached the silver-gray metal door that was almost completely closed, leaving only a slit.

Closer, closer.

As the pace approached, the consciousness sense was still slowly increasing, making Long Yun more convinced that the secret of the "dead city" should be related to this building.

Seeing that the entrance was in front of him, he first cautiously probed the surroundings, using his already slightly dull consciousness to snoop and sweep the surroundings, to make sure that there was no abnormal threat here, Long Yun temporarily put the acetylene blowtorch on the ground next to him, holding the gun in one hand and resting the other hand on the protruding metal doorknob.

Taking a deep breath and holding the gun under his armpit in his right hand, Long Yun slowly opened the heavy metal door. (To be continued......)
