All passages will be blocked to varying degrees, although the wall at each bend is to defend the front, and there is a heavy machine gun full of ammunition, but it has also become a position for the enemy to block the attack, and if you take the first step to occupy it, you can block the attack on this side, although it is not as convenient as this side of defense, and the firing port can be used as well.

The first two corners of the team members who entered were smooth, and they easily broke through, and the opponent had no chance to shoot, so they were killed by silent shooting.

But just after the team broke through to 100 meters, at the third turn, the garrison force of the left turning passage on the upper floor was alert, and after the fierce battle, although there was no damage to take the place, the gunfire was still heard by the people behind.

When breaking through to the fourth channel, the other side was in a hurry and was forced to retreat, retreating to the fifth channel, and at the moment when the headquarters could not be contacted, reinforcements came from behind the phone, and the heavy machine gun was turned to defend on the spot, blocking the straight passage of thirty or forty meters.

The attack was led by hedgehogs, and the attack was blocked, and the dense bullets blocked the narrow passage, so that they could not even poke their heads out.

The bullets hit the stone wall next to them, and the flying stone chips and bullet fragments hit them in the face, leaving bloody wounds and holes in their clothes, which were pressed there, and it was difficult to get in.

The hedgehog poked out his gun several times and fired blindly, but he couldn't stop the opponent's bullets, which made him very anxious, and he didn't know what was going on in other positions, so he brazenly used a grenade.

Thirty or forty meters, without a probe, smashed directly on the opposite wall, obliquely, and also bounced to the opposite position.

Rumble!

With a loud bang, the moment the air wave flames rolled over, the machine gun was dumbfounded.

Although it can't be blown up through the stone wall, the loud noise is just as uncomfortable, after all, this is a closed environment, and the area is still small.

The hedgehog rolled out, fluttering in the dust, and at a moment when it was still more than ten meters away from the bend, another grenade was thrown into the bend, smashed on the stone wall opposite the bend, and bounced into the bend.

Before the explosion, the two figures rolled out in horror, and before they could get up, they were beaten into a sieve by the hedgehog and the team members who followed, and then, with a loud bang, the dizzy guys who were shaken by the explosion just now in the corner were blown to pieces, and the fragments of limbs were sprayed everywhere, and the air waves and flames roared.

Although the three hedgehogs had already lay down, hugged their heads tightly, and desperately opened their mouths to shout, so that the viscera tightened, and the strength of the inner abdomen was reduced by the concussion, their ears were still buzzing, their heads were buzzing, and their heads were dizzy.

it! Such a powerful !!

The hedgehog waited for the heat wave to roll over his body, shaking his dizzy head, secretly shocked.

Here, it is a closed environment, and the shock wave of the explosion naturally has to be vented along the passage, and they are far away, and they will also be affected.

After his head was slightly sober, although his ears were still buzzing, the hedgehog knew that the fighter plane was fleeting, so he yelled: "Kill!" ”

The two team members were also dizzy, and they couldn't hear what the captain was shouting, but they could see the captain standing up, so they yelled: "Kill!" ”

In the roar, he got up and followed the captain's footsteps.

Turning the corner, there were no explosions in the back, but the concussion made their vision blurred, their ears buzzed, and at the moment of the hedgehog's arrival, their ears and noses were bleeding, and they didn't know how to resist, so they were shot in the head by the hedgehog and rushed over.

Although there was a successful breakthrough here, the explosion also let the next floor know that there was a change, and the sound of the explosion could not be heard clearly, but the vibration was very clear.

And so the fierce battle began, making the advance slow and slow. Then, the enemy, who had been bombarded by grenades and grenades, opened the firing port and warned with heavy machine guns.

It's a pity that the firing port is not enough to crawl past an adult, it is too narrow, the height is only more than twenty centimeters, and the blocked guy is like a trapped beast, desperately blocking it, trying to wait for the reinforcements behind to outflank the infiltrator.

Fierce gunfire echoed through the valley, letting more passages know that something had changed, and they made defenses one after another.

At this moment, the battle is stalemate, and the speed of advancement can be said to be slow turtle crawling.

Xue Lang rushed out of the closed portal, and immediately heard the explosion in the passage, couldn't help but be anxious, judged slightly, pointed to the two passages on the left and ordered: "Water leopard, you go down, rush quickly, grenade out of the way!" Be sure to get down on your stomach and avoid the shockwave! ”

"Yes!"

Zuo Boyang answered the order, and got into the passage on the left with a gun.

Xue Lang rushed to the second floor and got into it without hesitation.

Zuo Boyang moved quickly, and when the smoke and dust did not dissipate, and the lighting was also shattered by the shock wave and the bulb disappeared, with a night vision device, he did not run slowly, and he caught up with the blocked team one step ahead of Xue Lang.

Approaching the team members, this is how to know the reason for the blockage.

Two of the three team members were injured, one was wounded in the arm, and one was hit in the heart by a pistol bullet.

Zuo Boyang swept a shuttle, and the enemy who was about to break through retracted the corner, and while taking off the grenade, he said loudly: "Hurry up and bandage and treat, leave it to me here!" ”

As he spoke, he raised his hand and threw out a grenade.

The jingle rolling grenades startled the enemy and swooped into the bend to avoid the shockwave.

Zuo Boyang jumped up at the moment when the grenade was shot, the second grenade was in his hand, and he exerted force under his feet, as fast as lightning in the thick gunsmoke, and quickly advanced more than 20 meters.

How did the enemy know that the first grenade did not pull the safety out, and for the estimated time, lay tightly on the ground, dodging the shock wave.

But then, in the sound of jingle rolling, there was another jingle sound and it was right next to him, and even hit a person.

The five or six guys who turned the bend stood on end, screaming and pounced on the other side, turning over and pounced on the bend, like headless flies.

It's a pity that even if they left the front, they were too close to the explosion, and in the rolling of their bodies, they were headshot in the pop sound of rushing to the side of the passage, followed by a loud bang, the flames rolled and swept to both sides, turning the corner, still undiminished, roaring and pounced on Zuo Boyang, who was already lying on the ground.

Zuo Boyang had already followed Xue Lang's instructions to avoid the shock wave, but at the moment when the shock wave came, his head buzzed, and his ears were immediately deaf.

It's so powerful......

The shock wave swept by, Zuo Boyang shook his dizzy head, felt that his body seemed to be fine, shocked, jumped up, flew around the corner, did not shoot along the way, in the dust, the black knife flashed, swept by.

Even in the dark, even if his ears were ringing, it didn't delay him in judging the position of the person lying down, and even if there was a faint breath, he couldn't escape his life.

At the moment when Zuo Boyang and rushed through the block and rushed forward, Xue Lang also ran to the blocked position.

On the opposite side, although the enemy did not have grenades, because they could not be used, there were heavy machine guns, and the powerful fire blocked the corner of the passage, and the three machine guns also blocked the firing ports on the opposite side, covering the remaining personnel to break through the two lines of defense, forcing the three team members to retreat again and again.

If it weren't for the heavy machine guns on the walls around every bend, they wouldn't have been able to suppress the enemy.

But even so, one of them had a color on his shoulder and a bullet in his calf, and the three of them struggled to resist, and they were already overwhelmed.

At this moment, Xue Lang rushed over, patted the team members who were shooting desperately, and said loudly: "Bandage and rest." ”

As soon as they heard the captain's voice, the three team members were overjoyed and responded to the order. They had exhausted their physical strength and were bleeding, causing the other two to be at the end of their crossbows, and as soon as they slackened at this moment, they immediately lost their strength.

The only member of the team who was embarrassed quickly bandaged the seriously injured to stop the bleeding, and as for the warhead, there would be no time to take it.

Xue Lang did not control the heavy machine gun, but quickly moved the heavy machine gun away, and judged the position of the bullet sprayed from the firing port on the opposite side that could not even see the light of the fire, and pulled the trigger intently.

There were two pops, and the enemy on the opposite side turned around and defended the enemy with a firing port by the flying bullets, and the machine gun was dumb.

The ventilation in the passage was not smooth, the smoke from the heavy machine guns on both sides made the line of sight almost zero, and the light was completely empty, and suddenly they were hit with precision, and the three guys who were about to take the opportunity to touch it immediately became nervous, and slowly touched the corner.

After Xue Lang shot, he jumped up, quickly turned around, held the gun, was highly concentrated, and rushed quickly.

At a distance of forty or fifty meters, at the moment when the machine gun sounded again, it rolled and pounced into the corner, followed by the flash of the pitch-black knife light, and in the click, four knives in a row, cutting off the heads of four people in the breath, in the dull explosion of the tom heavy machine gun, in a flash, turned over the wall, the knife flashed, and mercilessly cut off two enemies who were blindly fired in the smoke. Swept by.

With a grenade, he will also suffer, of course Xue Lang knows that in a short distance, speed is king, so he gave up the grenade and forcibly broke through.

Due to poor ventilation in the cave, visibility is quite low, oxygen is thin, and the nasal cavity is full of the smell of gunsmoke.

But this did not delay Xue Lang from rushing quickly, and from time to time tactical moves to dodge, to avoid stepping on the slag and making a sound from being attacked by the other party.

In the rush, there was no obstacle at the junction of the two consecutive passages, Xue Lang did not stop running, still maintaining a speed of 100 meters, the wind in his ears was whistling, and he was rushing quickly.

After five consecutive turns, he suddenly heard the sound of a heavy machine gun in the distance ahead.

What, there are targets out there?

Xue Lang's footsteps did not stop, judging the location where the sound of the direct pounce came from.

Since there was no fighting, the smoke was relatively thin, the air quality was much better, and the visibility was higher, although there was still no light.

But Xue Lang's footsteps were also lighter, until he pounced on a corner, Xue Lang stood suddenly, listened attentively, the corners of his mouth curled, and then took out two tactical grenades, a flashbang, and a tear gas grenade, and then shot at the firing port where there was no heavy machine gun.

The front was full of smoke, not to mention that the sight was not good, the movement was too big, and he couldn't judge the exact location of the other party at all, so he came to startle the snake.

Sure enough, the bullet swept through the space, and the moment it hit the stone wall head-on, the sound of tom suddenly sounded, and the enemy opened fire.

Xue Lang flashed into the corner like lightning, raised his hand and threw a flashbang out.

In the sound of tom tom gunshots, no one could spot the flashbang near the base of the wall, but the sniper ports on both sides, the front ones, would be wide-eyed, staring at the opposite side, constantly firing to prevent people from approaching.

But at this moment, a cloud of incandescent light suddenly bloomed, and the three people who shot at the mouth shouted at the same time and closed their eyes and squatted down.

It's a pity that the eyes can't see anything anymore, so what about closing the eyes?

At the moment when the light lit up, Xue Lang jumped up, and at the moment when the gunfire disappeared, the cannonball shot forward, in just a few seconds, forty or fifty meters passed, followed by the shooting port in the smoke, raised his hand and threw the tear gas in his hand, rolling, in a panic shout, flew into the corner, paused slightly, followed the ghost to pull out, in a bad shout, not far away at the moment when the heavy machine gun stopped firing, flashed, turned the wall, held his breath, closed his eyes, and waved the ghost with his feelings.

In the subtle sound of cutting flesh and skin, blood swords were shot one after another, and all the five or six people behind the wall had their necks cut off.

Xue Lang's footsteps did not stop, and in the panicked movement sound in front of him, he dodged and pounced on a corner, stood abruptly, pulled down a grenade, raised his hand and threw it in.

In the jingle sound, a desperate shout sounded, and a figure rushed out in the thick smoke, followed by a loud bang, and at the moment when Xue Lang fell against the wall, a flame surged out from the bend, knocked over several figures, and rolled away.

When the shock wave passed, Xue Lang shook his dizzy head vigorously, jumped up, flew in the flutter, the knife flashed, and by feeling, he cut off most of the neck of the figure lying on the ground, and rushed into the corner.

In the strong air current, there was a mess inside, and the smoke swirled behind him.

Seeing the location of the leaking light, Xue Lang was shocked to find that these guys who had nowhere to escape were actually trying to gnaw out the escape passage with heavy machine guns here, and the rocks that were already thick with buckets and funnel-shaped were gnawed alive by bullets, but they were not yet able to drill out people.
