It can be seen that the tunnel has not been visited for many years, and the whole air is a smell of decay and decay.

When Lin Xiao looked underground, he found that there were railroad tracks that had been covered with thick dust, thinking that a long time ago, this was a train that could be directly driven in.

After walking a little further, you will see an abandoned steam locomotive, with a huge red star on the front of the locomotive, which is one of the most striking symbols of the former Soviet Union.

The long tunnel is tall and spacious, with a vaulted dome where you can still see the joints left by the pouring of concrete, and the walls on either side have some peeling skin from the dampness.

On both sides of the tunnel, you will occasionally see small round doors, through which you can find traces of people who have lived there for a long time, such as lounges, medical rooms, or simply small movie theaters for entertainment.

Of course, the indispensable thing is the guardhouse, and occasionally you can see the old-fashioned telephone or something, the kind of thick cable, which is no longer visible, that is, only in film and television works, you can occasionally see that glance.

After walking a little further, I saw rubble and garbage all over the ground, and even some paper documents that had been completely weathered.

Lin Xiao walked with his sword, but his spiritual power was able to detect all the movements around him in an instant, even if he didn't need to go deep into the huts on both sides, he could detect everything.

Obviously, there has been no sign of life here for many years.

In a medical clinic next to it, Lin Xiao even found an operating room with a full set of facilities and the like, it can be seen that there are many medical facilities left, although the shadowless lamp is destroyed, but in the cabinet next to it, all kinds of surgical instruments are still very complete, which makes Lin Xiao feel that the evacuation here at that time should have been very hasty, so there was no time to take anything away.

Because Lin Xiao even found the existence of a gun cabinet in the guardhouse, the cabinet door was open, and there were more than a dozen AK-47s neatly placed inside, but he didn't see anything like a magazine, it seems that the gun management system is still relatively strict, and the management of gun and bullet separation has been effectively implemented.

Lin Xiao went about a thousand meters deep inside, and put down more than a dozen probes to ensure communication along the way.

At this time, I finally saw a more spacious hall.

On the top of this hall with a radius of about 100 meters, there is a huge red star sign, and the dark red paint on it has basically been completely oxidized at this time, and it has long been impossible to see its original appearance.

In order to support this hall, every twenty meters or so, a thick reinforced concrete support rises up to the dome, and on these square concrete supports, there are reliefs in the image of former Soviet soldiers holding guns, which look very modern.

On one side of this hall, there is a large iron gate that is more than six meters high, almost a semicircle.

Lin Xiao installed two communication probes in the hall, and then took out the video communication and surveillance integrated device provided for him by the secret service from the ring storage space.

In fact, it is just a helmet, and after wearing it, everything he sees can be sent to the satellite through the communicator, and then directly transmitted back to the secret service, and then presented to Han Ya and their command system.

Lin Xiao turned on the switch of the helmet, and a second later, he was connected to the base of the secret service.

"Lin Xiao, how's the situation?" Han Ya's voice suddenly came from inside, looking very concerned.

Lin Xiao adjusted the video device on the helmet, so that the display screen was shifted to the front of his head, so that he could see it with a slight increase in his eyes.

At this time, he saw the images of Han Ya and several secret service experts on the other side.

In the command center of the secret service, there were about six or seven people, all of whom craned their necks and watched the situation on his side.

"It's relatively smooth, there are no signs of human existence along the way, this place has been abandoned for a long time, and there are no traces of human movement on the thick dust on the ground." Lin Xiao adjusted the camera, and then saw that the two-way communication module on the screen appeared on a small screen with his own head image.

"So, this base has been abandoned for a long time?" An expert asked.

"It's obvious." Lin Xiao's gaze circled around the entire hall, and he deliberately stayed on the ground for a long time, so that the experts on the opposite side could see clearly.

Finally, he fixed his gaze on the large, semicircular iron door.

"This is the entrance to the underground tunnel." Lin Xiao said with a smile, "The next thing should be an underground tunnel with a depth of four hundred meters, and after passing through this tunnel, we will be able to reach our destination." However, I think that after so many years of closure, this gate may have completely corroded. ”

Even according to the time of the collapse of the former Soviet Union, no one has used it for at least 20 years, and no one has maintained it for such a long time, in this dark and damp underground tunnel, it is impossible for such a large iron gate to continue to maintain its original condition, and rust is inevitable.

"Not necessarily." At this time, an expert spoke, "Secretary Lin, you must know that the former Soviet people are very extravagant in this regard, just like the gate on the surface, it seems to be an iron door, but in fact, it may be a gate made of titanium alloy, and this thing is basically difficult to rust." So, I'm almost willing to bet that if you make the right moves, this door can be easily opened. ”

"Really?" After Lin Xiao heard this, he was taken aback.

He walked over and paid a little attention to it, and sure enough, he found that this big iron door was indeed a little subtle, he thought about it for a while, and blew it out in one breath, blowing directly on top of the big iron door.

In terms of Lin Xiao's ability, blowing into a sword was not a lie, so when he blew it out, he saw that the rusty things on the big iron door were blown open in an instant, revealing the stainless steel-like surface inside.

"Sure enough, it's a little interesting......" Lin Xiao saw it, and couldn't help laughing, "They are really extravagant when they arrive, it is said that titanium alloy is a good material for making the shell of a nuclear submarine, but I didn't expect that the former Soviet Union even used this material to make the gate, and I almost got blinded to me." ”

"This is not an ordinary underground base, the design standard is to withstand a 10-million-ton nuclear explosion, and the gate naturally cannot be an ordinary iron gate." Han Ya replied on the other side.

Now all the people in the base headquarters of the secret service are paying close attention to everything displayed on the big screen, after all, this time, it is possible that it involves the study of aliens by the former Soviet people, and no one can say what will be discovered, but one thing is very clear, that is, the discovery of this big iron door alone is enough to prove that this trip is indeed not in vain.

"Okay, then I'll try it now, and see if I can open this door more easily." Lin Xiao spoke, and then pressed a hand on the titanium alloy door.

Heavy, heavy, this is Lin Xiao's first feeling.

He shook the door a little harder, and found that the gate didn't move at all, and there was no obvious tremor.

This is enough to show that the design of the gate is very tight, this kind of guide rail between the door and the door frame is tightly fitted, there is no gap, it is indeed relatively rare.

But if you think about it, I think it should be like this, after all, this place not only has to bear the power of resisting nuclear explosions, but also has to assume the role of defending against biological and chemical weapon attacks, if the gap in the gate is large, then the enemy's poison gas attack can easily penetrate in.

Lin Xiao's spiritual power began to spread along the gate in an instant, and then quickly found the location of the control organ.

Unexpectedly, this is a very simple design that uses manpower to control the opening and closing of the door, but it also sets up a set of combination lock mechanism, which is used to prevent someone from suddenly touching in.

Although it was almost impossible to infiltrate such secret military facilities in the territory of the former Soviet Union at that time, it was not afraid of 10,000, but it was afraid of what happened, so such precautions were also necessary.

It's just that when Lin Xiao's spiritual power penetrated in, the expression on his face changed slightly, as if he had discovered something not very good.

"What's the matter, did you find anything?" Han Ya had been paying close attention to Lin Xiao's every move, and their relationship was too close, so Lin Xiao had changed slightly, and Han Ya had already noticed it.

"Well, behind this door, there seems to be something not very good, I feel that there is a dead air in it." Lin Xiao nodded and replied, "It seems that the closure here back then was not so simple as an emergency evacuation, maybe something terrible happened that forced them to abandon this base." ”

"If you say that, I'll be a little reminded of Resident Evil, it can't be that there is some T-virus here, right?" Han Ya said with a smile.

"It's hard to say, after all, the former Soviet military did try to research human and biological weapons at that time, but it was not so clear what it did later, after all, it was far more difficult to figure out some things in the former Soviet Union than to understand the 51st area of the Americans." An expert said from the side.

"No matter, let's go take a look first." Lin Xiao smiled, then put his hand on the gate and began to exert his strength.
