In the passage of the outer area of the biochemical laboratory located under the jungle, the red alarm lights have been flashing silently, and several base guards armed with AK74 assault rifles, wearing jungle digital camouflage uniforms and tactical vests, have hurried past the metal security door that is about to close.

Seeing that the thick security door behind him was finally closed, several base guards slowed down the pace of wearing training boots, and their frightened expressions quickly turned solemn, the scene just now was terrible!

A small group of more than a dozen base guards were ordered to search and advance to the helicopter hangar area, intercepting outsiders who broke into the base, and when approaching the personnel outside the helicopter hangar to enter and exit the evacuation passage gate, they were caught off guard by several jungle leopards, and a few base guards who were lucky enough to walk behind and saw the bad situation, taking advantage of the brief moment when their companions were still fighting with the jungle leopards in vain, and then won the body cover speed to retreat, and manually closed the alloy gate after retreating back to the alloy security door that was not closed.

In less than ten seconds between the time they retreated and the time they closed the alloy gate, the surviving base guards could not forget the terrifying scene of a few companions being torn apart by the sharp claws of the jungle leopard, and the smell of blood permeating the howls in front of them.

Several jungle leopards were clearly premeditated, waiting for the rabbit to swoop out silently as soon as the squad base guards walked to the turn of the passage, the speed of the human body was extremely fast and the angle was extremely tricky, even if the base guards behind shot and fired, it was difficult to kill a few jungle leopards in the chaos, the desire for life and the fear of the jungle leopard biting people's neck memories were intertwined, so that the remaining base guards made a "wise" choice, giving up their companions who had no hope, and retreating to the alloy door of the passage to close the alloy door, Successfully fend off several Jungle Leopards and Intruders.

Who would have thought that when everyone secretly breathed a sigh of relief and stood behind the alloy door with guns on guard, a moment later there was a dull crashing sound on the thick gray and white cement wall on the side of the alloy door, and there was a clear feeling of vibration on the floor of the passage, as if something was trying to break down the cement wall that the Russians had built with high-grade cement and steel bars decades ago?

Just when several base guards looked at each other and felt that they were in a very strange situation, the guards of the base integrated control room reported an almost collapsed intelligence through the individual intercom that the internal communication line was going to pass: through the video image displayed by the real-time monitoring of the monitoring probe, it was confirmed that three intruders, a man and two women, had approached the alloy door, and the man was making every effort to break down the high-grade cement wall on one side of the alloy door. And his actions seem to be fruitful, judging that there is a possibility of breaking through the concrete wall, it is recommended that the guards retreat to the second alloy gate and wait for reinforcements!

Several well-armed base guards have never encountered such an extreme situation, and after exchanging glances with each other and agreeing with the suggestion of the integrated monitoring room, they began to run deeper into the passage, preparing to manually close the thick alloy security door again after passing the alloy door position (in fact, it is to find a red switch box on the wall, lift the switch box, and unplug the switch in a total of three steps, and it only takes a few seconds to move fast enough to guard).

Now a few intruders are still in the outer passage of the biochemical laboratory base, the alloy security door of the security passage is usually retracted into the passage wall after opening wide, the Russian style of acting a few decades ago is concise and pragmatic style highlighted, thick and hard cement walls and alloy security doors comparable to three-proof doors, there is no need to lay too many electronic equipment.

The access cards carried by the base guards are not used at all at the alloy security doors of these peripheral passages, and are used to patrol the more in-back common areas of the laboratory to swipe open a large number of doors.

"Bang! Boom! Boom! ”

"Poof"

"Quick, unplug the switch, the concrete wall has been punched through!"

A few base guards who ran back in the dull noise of demolishing the cement wall, suddenly heard a muffled sound different from the demolition of the wall, a bold blonde and brown-eyed white base guard in his thirties, glanced back at the alloy security door behind him on the way to run, and found that the cement wall on one side was splashing everywhere and was filled with smoke, could it be so fast to penetrate the cement wall more than a meter thick and reinforced masonry? After a question flashed through the mind of this base guard, the speed came back to his senses, isn't it true! His face immediately changed and he yelled in English, signaling the companions running in front to close the switch and close the alloy safety door, and at this time, several companions had not yet run to the wall of the passage set up by the alloy security door, and it was still a lot of meters away!

After only a few seconds, the alloy safety door was closed, and finally moved out of one side of the concrete wall while everyone was anxiously waiting, and moved sideways to the other side of the wall to embed a part of it, and then closed completely.

This made the nervous hearts of several base guards relax slightly, but they already understood that this was not a place to stay for a long time, and it was too easy for an intruder who could break down the wall with both hands without tools, and it was too easy to tear a person apart, encountering such an extremely asymmetrical and tough opponent, the assault rifle in his hand might not play much role, and several base guards were unanimous in speed, and in order to better "defend", they evacuated to the depths of the base again for a distance, where there was an automatic weapon station and preset defense bunkers, equipped with corresponding weapons arsenals, There are light and heavy weapons and a number of ammunition stockpiles in stockpiles.

The automatic weapon station was laid later, but the so-called defensive bunker was simply a small space carved out of masonry in a concrete passage, which was a proper Russian style, and it is needless to say that it is solid.

In the eyes of these base guards, when they get there, they use the access card to swipe open the arsenal, stay in the defense bunker, first have the large-caliber weapons of the automatic weapon station to greet the intruder, and then there are all kinds of light and heavy weapons around them, even if Superman comes, he has to lie down, and the various passages of the base are only a few meters wide and high, and the Superman built by the Russians back then can not be used, as long as he insists until Robert, the director of defense, orders other base guard companions to rush to support, why not kill the intruder, Several of the base guards also understood that there was no reason to retreat further into the base when they got there.

After unifying their understanding, several base guards of different skin tones continued to run deeper into the passage with guns in their hands, and the red alarm lights and the white wall lights were reflected by the light of the flickering red sirens and the white wall lights, except for the sound of footsteps running farther and farther away

At the same time, not far from the second alloy safety door, Song Xiaoshuang, who had bypassed the security door through the big hole in the cement wall that had been opened, ignored the cement dust covered his body, unscrewed the flat kettle from his belt, unscrewed it and covered it, poured a mouthful of water on his head, rinsed his mouth, drank the drinking water in the flat kettle, and waited for Liang Li and the black girl Heina in the back.

He carefully walked through the big hole in the cement wall at the moment when the second alloy security door was closed, and just saw the alloy door embedded in one side of the wall, Song Xiaoshuang exhaled, secretly thinking that it was better to wait for Liang Li and Henna to come over, and walked along the passage to the front of the second alloy security door and stood down and rested for a while.

Of course, it is impossible to smooth a big hole in a very short period of time, but there is a steel skeleton in the cement wall, and the broken steel bar can easily hook the clothes and pants and even cut the skin and bleed if you are not careful, of course, this means that Liang Li and Henna behind you may be injured, of course Song Xiaoshuang will not be so careless, even if the broken steel bar touches him, it is difficult to hurt him, as a cultivator of ancient martial arts and abnormal abilities, there is no need to mix up if he is injured by the outcropping steel bar.

"This is a fortress passage built in a typical Soviet style! It is a product of the Cold War between the United States and the Soviet Union, when I was consulting information to complete the relevant preliminary intelligence preparation for the employment task of an employer, I once retrieved similar underground structure intelligence introduction in the large data database of the military employment contracting company, if I guessed correctly, there is no longer this kind of solid alloy security door similar to the three-proof door, it is not ruled out that there will be a defensive fortress behind, and those base guards should be there waiting for us to collide! ”

A jungle leopard shook its long speckled tail and walked around Liang Li twice before walking away and standing with its companion, Liang Li was not angry and glanced at the black girl henna who was not far away with a childish face and commanded the action of the jungle leopard, Liang Li shook her head slightly and felt a little speechless, not long ago, henna commanded a few jungle leopards to tear apart a few base guards.

Later, Liang Li took two steps and stood next to the ears of Song Xiaoshuang, who was drinking water and covered in cement dust, did not remove the jungle green dusty Penny hat on Song Xiaoshuang's head, almost biting his ears and whispering Chinese, Liang Li noticed that Song Xiaoshuang was just a little drunk after the action, after continuing to drink two sips of water, he turned on the flat kettle and hung it back on the belt around his waist and stood still, Liang Li understood that Song Xiaoshuang was thinking rapidly, according to his own way.

Liang Li was about to walk away, but she felt that Song Xiaoshuang was turning her head, knowing that he had already made a plan, so she kept her posture still.

Seeing Song Xiaoshuang's lips getting closer and closer to the cement ash stained lips, Liang Li had an urge to kick him, all the beautiful thoughts were gone, only to see Song Xiaoshuang's lips getting closer and closer to her cheeks in the end, Song Xiaoshuang said in a low voice: "The fortress passage here is significantly different from the underground passage we encountered last time in the Asian jungle, Liang Li, how does this look like a biochemical laboratory base?" Are you able to tell the difference between the two? ”

After Song Xiaoshuang finished speaking, he waited for a few seconds and didn't wait for Liang Li's answer, but he felt that Liang Li's body temperature was rising significantly, because her face was hot, Song Xiaoshuang had no choice but to grab Liang Li's wrist with cement ash and let her come back to her senses, Liang Li suddenly whispered, her voice was low and gentle, but Song Xiaoshuang felt a little numb in her back
