The two forces converged, flanked back and forth, and soon crushed them.

Seeing this, the others retracted again, these K-organization killers were very weird, relying on their familiarity with the terrain, and they were elusive.

But when they found that the situation was not good, they immediately retreated.

Defend the cave and not fight.

In this kind of place, if Qin Mu wants to attack it, it is even more difficult than ascending to the sky.

After the two groups converged, Shen Tianlong came over with a gun, "Master, these bastards are too cunning, and they have fallen for their tricks several times. ”

Qin Mu saw that everyone was safe and sound, and ordered to go down, "Everyone hurry up and count the ammunition, and pick up the ones on the ground if they are not enough." Especially grenades, don't let go of one. ”

The crowd sprang into action and picked up the ammunition on the ground.

Qin Mu and Shen Tianlong summed it up and divided the number twenty people into four or five squads.

There are too many caves here, which are intricate, and it is inconvenient when there are too many people.

Shen Tianlong summed it up and immediately ordered to go down and reorganize the team.

In the end, it was decided to work in groups of four, and everyone remained on high alert.

The ammunition was also sorted out, and everyone brought at least seven or eight grenades.

Under Qin Mu's instructions, the five squads set off.

Infrared sights, which brought them convenience.

These killers, lurking in the shadows, have lost their advantage.

After Qin Mu and them were broken into pieces, they became more flexible and mobile.

And they are not afraid of being dumpled by the other side, once any detachment is in danger, other detachments can rush over to support as soon as possible.

The five detachments advanced layer by layer, and came to the location of the water elimination hole.

Everyone waded cautiously through the water.

The front of him actually became open.

Qin Mu paid attention to the entire cave and found that it had been artificially repaired.

Qin Mu's team was the first to wade through the Elimination Water Cave, and immediately after, other detachments gradually came over.

This cave is incomparably deep, no one knows how far it is, everyone is fighting and chasing, at least four or five kilometers have been gone.

Then the cave begins to whirl, going deeper into the lower level.

On the way, they kept encountering lurking gunmen, and after Qin Mu changed his strategy, they could no longer attack everyone like before.

The gunfire was getting closer and closer, and several small leaders in the depths of the cave panicked and ran over in panic.

"Dr. Peng, Dr. Peng, something is wrong, they are killed!"

Dr. Peng's face darkened, "What are you doing to eat? ”

In the base, only a few leaders and Dr. Peng's assistants, the nurses can speak, and the other killers are all mute.

The little boss said in a panic, "They're too powerful, they don't look like ordinary people." Could it be that the special forces came from?"

Dr. Peng looked at the screen, and there were more than a thousand cameras installed in these caves, large and small.

They can see exactly what these people are doing.

Just now, Qin Mu divided the Twentieth people into four or five groups, and Dr. Peng knew that the situation was not good.

For Qin Mu and them, the fewer people there are, the more room there is to exert themselves.

Dr. Peng saw them kill all the way and soon reached the third layer.

There was a huge cave over there, and the whole cave was empty without any obstacles.

Dr. Peng said coldly, "Let them come!"

After speaking, a pair of eyes stared at the screen coldly.

Qin Mu was the first to rush to this cave with the three of them, and found that the place was cleaned up by hand, without even a trace of cover, so he had an instinctive vigilance in his heart.

"Be careful, everyone, there may be a problem here!"

Before he finished speaking, several muzzles poked out of his head, "Click-"

Suddenly firing without warning, a dense stream of bullets came over, and Qin Mu hurriedly shouted, "Withdraw!"

Click-Click

The machine gun at the top of the cave is automated, does not require manual operation, and the muzzle can be rotated three hundred and sixty degrees.

The bullets hit the ground, scratching bullet marks.

Qin Mu and the others quickly withdrew.

Now he finally understood why this place was so clean.

A few points of fire covered almost all the area, and not even a single mosquito could go there.

Unless you have the ability to take those fires out.

But these firepower points are not like the bunkers in the movie, they are fully automatic, which is very tricky.

Soon, Shen Tianlong also came with a team.

Looking at a few firepower points, "Master, this is very troublesome!"

Qin Mu said, "Not only that, but there may be some around." ”

The walls of the entire cave are complex, and who can guarantee that there will not be a few fire points in those places?

Other detachments came one after another, and they stayed on the top to hold the retreat.

Qin Mu observed for a long time before he picked up his gun, "I'll try it!"

I saw him holding a gun, aiming at the fire point above, and bang!

Suddenly a point shot.

The bullet landed exactly as it struck the fiery gunfire.

Shen Tianlong secretly shouted "Okay!"

Click-Click

It's a pity that the bullet that hit was actually reflected.

Grass!

Qin Mu was annoyed for a while.

Behind him, Leng Feng was shouting, "It's not good, they've outflanked me." ”

it!

If this continues, they will make dumplings again.

Qin Mu glanced around, and could only take a risk.

"Shen Tianlong, take the sword!"

Forehead?

Shen Tianlong was stunned, "Master, what do you want a sword for?"

Although he was puzzled, he handed over the sword.

Qin Mu grabbed it in his hand, his eyes glaring at the machine guns hanging from the ceiling.

Suddenly there was a shout, "Yikes!"

The whole person jumped up and waved the sword in his hand.

Click-

Boy.

He actually cut off the machine gun hanging from the ceiling with a sword.

The sword that sharpens iron like clay is the bull.

The crowd applauded.

After Qin Mu landed, he rolled on the spot.

The people in the control center were confused and held the grass.

What kind of play is this?

He actually cut off the machine gun with a sword.

Someone decisively pressed the button, "Fire!"

Click-Click

The remaining few machine guns opened fire again, covering the entire cave.

It's just that after one machine gun is missing, a dead end is naturally exposed.

Qin Mu seized the opportunity, rose to the sky, and brushed!

With such a divine weapon, isn't it handy?

A few swords will split the machine gun mounted on the ceiling, and a few machine guns will suddenly be dumb fire, where will everyone miss the opportunity?

Rush over and fight your way to the bottom.

Leng Feng led the people back step by step, and soon retreated.

Breaking through their machine-gun array, the crowd came to this cave in all directions.

The Twenties are divided into five groups, each looking for a target to advance.

Qin Mu and the others searched for at least several kilometers in the cave before they heard a huge sound of flowing water.

Rushed to the side of the flowing water, looked up, and saw a waterfall falling from the sky.

"This is probably the water elimination hole we just saw, and the water falls from above and flows into the dark river. ”

Qin Mu said, "Everyone search carefully, their headquarters should be here!"

The strata of the cave are really a bit messy.

Dr. Peng was also a little uncontrollable, "Everyone is ready to withdraw!"

"Withdraw?"

The two nurses asked, "What about these people who have just finished surgery?"

Dr. Peng took off his white coat and said, "Close the door, let off poison gas, and never let them find evidence!"

The little boss next to him decisively pressed the button, and the door of the ward slowly closed.

From the countless small holes in the wall, puffs of poisonous smoke emerged.

The poisonous smoke instantly enveloped the entire ward, and these people who had been anesthetized on the hospital bed died almost unconscious and in pain.

A nurse next to him asked, "Doctor, are we going to leave like this?"

Dr. Peng said coldly, "Pass the order and kill them in the base at all costs, this secret must not be leaked!"

Dr. Pang threw away his lab coat and retreated into a corridor with several small leaders and nurses.
