At the moment when darkness fell, Xue Lang's three groups of people were screaming, and at the same time as the aroma suddenly filled, the night vision device was buckled, ghostly flickering, and there was no figure between breaths.

Liu Yucheng and the others followed up to make defensive moves, and the muzzles of their guns were all pointed in the direction they came, close to the cave wall, and they didn't even bring night vision devices, and a group of two people squatted down quickly.

The moment darkness fell, there was a whispered riot in the cave, and in less than two seconds, the emergency lights were lit one after another, illuminating the cave green, like hell.

At the same time, the loudspeaker of emergency communication sounded: "All parts are on the defensive!" This is not a drill! Check the power supply system for vandalism and restore lighting quickly! ”

As the sound echoed through the layers of passages, four seconds after darkness fell, all defensive positions entered a tense defensive state.

Columns of flashlights swayed in the dark, and the power supply unit quickly rushed to the power distribution room to find out what caused the power supply to be turned off as a whole.

In the passages, there are no portals, and they are all built on the basis of natural caves. If you are not familiar with it, let alone get lost in it, it will be difficult to find at least a location.

But no one would think that there was an enemy breaking in to sabotage, so it wasn't very nervous. After all, there is still defense on the surface, and there is no movement at all, how can it be an enemy invasion?

There are handles on each floor, and in the dark, although there are no night vision devices, if there is a sound of running in the passage, they can hear it.

As long as the illuminated flashlight is on, it is a dream to enter the next floor in the unobstructed passage.

But at the moment when everyone pricked up their ears to listen to the movement, they suddenly smelled an extremely good smell, and at the same time heard the sound of air leaking, blowing like the wind.

This is......

Before the thought was finished, they suddenly felt weak, lazy, and sleepy, and slowly fell to the ground, and then fell into a deep sleep.

Xue Lang and Zuo Boyang were as fast as thunder, and they quickly advanced downward layer by layer.

On one side of the backpack of the two of them was a spray bottle that had been pressed to the fast gear, and where they passed, the rich aroma quickly diffused, and a fragrant wind rushed to the ground quickly.

The two groups of Du Rui and the gold-loving rat were not two seconds apart, and they also broke into the second underground floor, and the speed was so fast that the personnel defending at the intersection only heard a slight sound, and it was only a moment's work before disappearing, and then, they fell asleep in the rich aroma.

In five seconds, the personnel in the power distribution room rushed to the equipment, checked the wiring under the flashlight, and tried to restore the power supply.

In six seconds, Xue Lang and Zuo Boyang ran to the third floor and went straight down to the fourth floor.

In seven seconds, Xue Lang rushed to the last position against the slightly cool and humid airflow.

In eight seconds, Du Rui and his two groups also broke through to the fourth floor, all the way without hindrance.

When they had just broken through the intersection of the third floor and went down to the fourth floor, in the power distribution room, the computer suddenly restarted with a buzz.

Amid the sound of dripping, computers restarted, equipment using solar batteries was started, and the stopped generator sets were warmed up.

The person who was still checking the wiring gave up on the backup solar power and quickly ran to the lit screen to check the status of the system after it restarted.

In nine seconds, Xue Lang and Zuo Boyang rushed out of the four floors of room by room, along the passage, facing the increasingly humid and cooler airflow, and while hearing the sound of running water, they rushed into a spacious cave one after the other.

Immediately, the two of them separated left and right, and while running, they saw the vents on the cave wall, followed by the spray bottles of ylang-ylang, and the two of them jumped up and ran along the artificially repaired cement wall and hung on the steel bars outside the air vent.

Ten seconds later, the generator set worked with a bang, and the lights that went out suddenly turned on, attracting a burst of cheers.

The power was restored, and all the power systems that were not turned off followed suit.

The monitoring system boots up and the screen lights up. When the ventilation system is activated, the fan reaches its maximum speed in the breathing room, pumping a rich aroma, blowing the intoxicating fragrance from the fourth floor to the third and second floors......

Du Rui and the gold-loving rat two groups at the same time as the lighting was restored, they also made a move, the two of them separated left and right, using the means of running the wall, the figure was almost illusory, and the hook on the mid-range spray bottle was hung on the steel bar one by one, and the figure was non-stop, almost unreal.

The distance of tens of meters between one person and three vents is only a matter of seconds for Xue Lang and them.

When the lighting was restored, three seconds later, the monitoring system was restarted, and one by one the images appeared on the screen.

At the moment when the people in the room were relaxed, in the monitoring room, a pair of eyes first looked outside, checking the situation outside the hole, retrieving the defense system, and checking the surrounding abnormalities. Unaware of the fact that a strong aroma wafted into the room, quickly filling the room.

Suddenly, a guy saw the strange appearance of the defenders at the intersection of the two floors, and was about to shout, when a feeling of sleepiness hit him, and he followed him to the workbench.

At the same time as he fell down, the guy next to him sniffled, and the feminine moment that had just turned in his mind suddenly fixed on the figure on the screen with a gun on his back and a knife.

No......

Before the good words could be spit out, an irresistible sleepiness followed, and then he lay on the workbench, and did not have a chance to ring the alarm.

At the same time as he fell down, in the entire defense core, one by one, whether they were walking, or staring intently at the screen, the figures fell softly, followed by the sound of snoring, intoxicated by the rich aroma, looking for their respective sweethearts, whether male or female, to do what they liked.

The exhaust fan reaches a wind force of more than seven levels, and the speed of the wind generated is tens of meters per second. Even if the pipe is long and the wind weakens when entering each room, it still does not delay the speed of one or twenty meters per second, and the difference is only the time it takes to blow through all corners of the room.

However, it doesn't take a few seconds, to put it bluntly, three seconds and two seconds are enough for the aroma to permeate the entire four layers and spread to the third layer.

The flying eagle held the gun, highly concentrated, staring in the direction of the entrance, ready to shoot at any time.

Although his skills are not as good as these people, and he can't catch up with Xue Lang, he is still confident in his marksmanship.

In the rich aroma, prepare to regain your lost dignity with excellent marksmanship.

The elite of an elite, the sharp blade of the country, has actually become a burden, how can he let go?

But it was quiet outside, and there was no movement. There were no alarms, no figures entered, not even the people in the portal in front of them.

How? Didn't have a chance to dive in, hibernated?

Flying Eagle's eyes were empty, and he looked at Liu Chengcheng beside him, and saw that Liu Luocheng was carrying a stick in one hand and a pistol with a silencer in the other, and the corners of his mouth twitched.

You don't need to use a pistol with an assault rifle......

At the moment when he wanted to think about it, Xue Lang and Zuo Boyang had already returned quickly and re-entered the spacious passage.

The shot just now was that he ran to the entrance of the passage with a knife, paused, and waited for Zuo Boyang's moment, and it took less than half a second to be captured by the monitoring room.

At the moment when all three of them rushed back to the passage, the entire sprawling base was slowly falling into a deep sleep.

Xue Lang and Zuo Boyang took a look in the cave without a portal that they were passing by, and when they saw that everyone had fallen, they quickly ran forward, knowing that ylang-ylang had to play a complete role.

Their direction is the core of the place, and it is also the area where the outer defenses cannot get close. The whole third and fourth floors, they can't come down, even if there is no portal.

The speed of the two of them drifted through the passage like a wisp of green smoke, and in just a few seconds, they ran to a position with a metal gate.

Xue Lang made a gesture and began to study how to open the portal.

Here, a password is required, instructions are required, although it is different from the Iron Scorpion Mercenary Group, there is no such trouble, but it is not easy to open.

The signals here are all blocked, and there is no need to think about connecting Lu Jin. Ice cream flowers should do, though.

Zuo Boyang's figure flickered, and he returned quickly, in Xue Lang's research skills, he ran to the four people who defended in about ten seconds, and at the moment when Liu Chengcheng turned his head to look at it, he ran to the front and whispered: "Bing Linghua follow me, the two of the flying eagle and the moon fox defend the entrance of the cave, drill the sky rat and wait for Du Rui and them, and then spread out to erase the defenders outside, one of them don't slip through the net, kill them directly." ”

"Yes."

All should be commanded.

Although the flying eagle received the order, his heart was completely clouded.

That's the end of cleaning up the perimeter? Why is there no movement at all! There are more than 600 defenses in this layer, so don't care?

But he watched Bing Linghua and Zuo Boyang turn over and run back, followed Du Rui, Xu Gang and others out of the horizontal passage one after another, and passed by Bing Linghua and them, knowing that he was afraid that he really controlled here.

How did they do it......

The eagle felt a tremor ring in his head.

This kind of weird ability, if it is a storm in the country, can it stop them?

Shocked, watching Du Rui and the others take off their backpacks, put down their spears, draw their short blades, and quickly disappear in front of the corner, and at the moment when Liu Ruicheng patted him on the shoulder and signaled the defense to move forward, he was still straight.

When Zuo Boyang and Bingling Hua arrived, Xue Lang hadn't opened the door yet. Without a computer, he had no way to do anything other than to blast it by force.

Bing Linghua didn't hesitate, and quickly opened the computer to connect to the door system when he got closer, followed by the phantom of his two hands, and a dense crackling sound sounded at the same time.

Xue Lang stood in front of the door with a ghost in one hand and a pistol in the other, and did not relax.

He was worried that this place would be the same as the Iron Scorpion Mercenary Group, and there would be some secret research room or something like that.

Zuo Boyang is the same, with a Tang knife in one hand and a pistol in the other, he is equally cautious.

I almost died last time, but I don't dare to take it lightly this time.

Bingling Flower really lived up to expectations, and in less than a minute, it successfully opened the door.

The moment the door slowly shrank to both sides, Xue Lang and Zuo Boyang's bodies were like electricity, and in a flash, they disappeared into the door, and at the moment when Bing Linghua packed up the computer and didn't stand up, they rushed to the core area of Nuoda's glass curtain wall.

Seeing the people lying upside down all over the ground, and those sleeping in front of their respective computers, Xue Lang and Zuo Boyang did not breathe a sigh of relief and relaxed, but continued to run wildly like a lion pounced on a rabbit, and their figures flickered, going straight to the end.

As soon as Bing Linghua stepped into the gate here, Xue Lang's pupils shrank suddenly, and he flew towards an open cave door.

Zuo Boyang dodged and pounced on the opposite portal, not staying at all.

The moment Xue Lang rushed in, there were four people standing in the room, who seemed to be a little confused, their bodies were shaking, but they just didn't fall.

At the moment when Xue Lang pounced in, the four of them turned their heads almost at the same time, and a fierce light flashed in their blurred eyes.

There are monsters!

There was no emotion, only a murderous gaze that made Xue Lang's pupils shrink suddenly, and in the flutter, the muzzle of the gun trembled slightly, and in the pop sound, the four bullets flew towards the four people almost in order.

At the moment when the gunshot rang out, the eyes of the four guys who were a little drunk suddenly flashed with a fierce light, and in the strange shaking of their bodies, in the sound of poof, the heads of the three guys spewed blood mist, while the other one howled, his voice was sad and angry.
