When they saw the endless clouds in the distance, they were nervous to get into the chariot or hide in the shelter.

There are some big trucks on the streets.

These vehicles have been modified, and the defense has been improved by I don't know how much compared to the previous one, and soldiers can hide inside and shoot through the shooting holes beyond the outside.

Some time ago, the scattered flying mutant beasts attacked them, and they relied on this method, and at a very small cost, they achieved great success.

In addition, there are some ground bunkers on the ground that cannot be moved.

The shooting of this bunker is very different from the previous ones, and it can be designed not only to target targets on the ground, but also to launch attacks on targets in the sky.

Of the three, the most numerous are the bunkers.

After all, the number of vehicles and combat vehicles is extremely limited, and these two kinds of guys are also very fuel-guzzling, and the bunkers on the ground are different, and the construction objects can be described as varied, the best is reinforced concrete, but this number is not much, most of them are built on the outermost defense line of the base.

The second is made of discarded bricks, as well as wood, and steel such as discarded cars, which are the most numerous.

Although the defense is not as good as the pure steel and cement, the defense is still not bad.

Compared to those makeshift bunkers made of wood and sand, it is already much better.

"Attention units, quickly enter the position!"

"Attention units, quickly enter the position!"

The sound of the horn sounded at this moment, followed by a long warning sound, and the sound was very harsh.

Qin Chuan closed the door, closed the curtains, and looked out through the gaps in the curtains, Qin Chuan didn't dare to expose such a big momentum to their sight, it was purely an act of looking for death.

Even if those flying animals were all first-order mutants, Qin Chuan couldn't bear them, because there were so many of them that they were terrifying and desperate. According to Qin Chuan's understanding some time ago, and yesterday's verification, the flying beast was not only as simple as a first-order mutant beast, but also a large number of second-order mutant flying beasts inside, and even an extremely small number of third-order flying beasts.

Qin Chuan had previously analyzed the reasons for the emergence of beast tides of mutant beasts.

Not only Qin Chuan understands, but some other wise people also know.

The reason why they start the beast tide is because of food.

Yes!

It's food!

The food of a population is limited, and they reproduce very quickly, and the team grows very quickly, in this case, if you want the population to continue to grow, you must expand the territory and expand the hunting range.

This beast tide is a large collection of various mutated animals, although they are also hunting each other at the moment, but more of them are coming in this direction.

This is an indication of a problem.

That is, there are some leaders in these groups who have a certain ability.

They have gotten rid of the unbridled hunting of each other at the beginning, and they have turned their spearheads, not fighting each other, but aiming at humans.

It wasn't just Qin Chuan who saw the scene in the sky.

Some of the people who didn't manage to hide in the underground defense base also saw it.

Their eyes were full of horror as they looked at everything in the sky, and it was so terrifying and desperate.

But they all watched silently, without making a sound.

Because the events of the first two days told them that in this case, the best way is to hide themselves, reduce their sense of existence, close the windows, curtains, etc., and those who have basements hide in the basement, although it is not as good as the underground base, but compared to other places, it is already much better.

Loud noises, that would only attract the attention of the birds in the sky.

Once you get their attention, your fate is sealed.

You will surely die in the mouths of those flying birds.

Your blood will be consumed by them.

Your flesh will be eaten by them.

In the end, all that will be left is a skeleton without flesh and blood.

The terrible screams still echoed in their minds.

They had watched a soldier swoop with mutated birds, and in just a few minutes, a large living person was left with only a pile of skeletons.

They want to live!

The desire to survive made them stop their fear and carefully hide themselves.

Here it comes!

Attack! 、

Da-da-da-da!

Gunshots rang out!

The sound is very crisp, and the repertoire of the attack is played.

The birds in the sky heard the sound, let out a series of strange calls, and quickly pounced from the sky downward.

After evolution, they not only have super good eyesight, but they are also extremely sensitive to breath, although they can't see the crowd below, but they can catch the breath below, and add sounds, so that they suddenly attack down like dumplings.

Rattle!

All kinds of chaotic sounds rang out constantly, accompanied by bursts of gunfire.

The power of gunpowder is still enormous. has a huge lethality,

I saw that the dense mutant beasts in the sky were shot down, and after a while, the surface of the ground was covered with a layer, like this case, the shooters hiding in the bunker didn't need to aim or anything, they only needed to attack the black clouds, it was ironclad, and it was ironclad that it would be able to shoot down a large number of mutant flying beasts.

Although it was easy to hunt down many mutant flying beasts, the soldiers hiding in the bunker did not let up at all, because they knew that it was just the beginning.

Now being shot down is basically the weakest.

Most of these were first-order mutant beasts, and first-order mutant beasts were the most numerous in the sky, but they basically didn't pose much of a threat to the soldiers below.

What they need to worry about are second-order mutant beasts and terrifying third-order mutant flying beasts.

They are the real source of disaster.

Second-order mutant beasts already have strong defensive power, and it takes a lot of effort to defeat them, let alone third-order mutant beasts with a certain amount of intelligence.

A large number of Flying Beasts are killed.

Succeeded in infuriating the flying swarm above the sky.

They let out bursts of angry screams.

Then there was an even more frantic rush towards the fire points below.

Qin Chuan watched all this silently through the window.

It's not that I don't want to help, it's that it's not time yet. After all, he is also a human being, and it is necessary for him to provide some help in the face of this alien attack.

Now these pounces are nothing more than first-order mutant beasts.

Although there are many of them, they can still be solved with the firepower of soldiers.

What needs to be worried are second-order and third-order mutant beasts.

They are the real protagonists.

And if you think of evolutionaries like Qin Chuan, they have their mission, which is to kill those powerful mutant flying beasts, and it is best to carry out a decapitation operation.

As long as the strongest person in it is killed, then it will be able to survive this beast tide.

Qin Chuan's target was those third-order mutant beasts.

Third-order mutant beasts, the leaders of their populations, they command those first-order and second-order mutant flying beasts to attack, as long as they kill the commander of a population, the attack power of that population will be greatly reduced, and the first-order mutant beasts and second-order mutant beasts without command can be annihilated by soldiers.

And now this kind of organized, planned flying beast attack is the most troublesome thing.

The base has allowed a lot of powerful second-order and above evolutionaries to do this kind of thing, and now they are basically the same as Qin Chuan, hiding in a ruin, silently watching all this in front of them.

Waiting for the opportunity.

Wait for those third-order mutant beasts, or second-order mutant beasts to arrive.

Boom!

A sound caught Qin Chuan's attention.

Qin Chuan looked at it.

I saw an evolutionary suddenly jump out of the building, covered in all kinds of armor, wearing a well-defended helmet, and holding a long knife in his hand.

One knife down.

Dozens of mutant birds were cut down.

After the slash, he didn't continue to attack, but quickly hidden, but it was not that simple, more mutated flying beasts attacked him.

Qin Chuan shook his head

"An unlucky fellow."

The reason why he was exposed must have been because he didn't hide it well, and he was discovered by the mutant flying beast, and he had to jump out in order to break through. Although it then disappeared very quickly, it was exposed to the sight of those flying beasts after all.

It's not easy to escape at this moment.

Although he has very tight armor, he can easily block and kill those first-order mutant beasts.

But it's definitely not that simple.

The evolutionaries who came to participate in the decapitation mission, each one of them was wearing strict armor, the person just now was just ordinary steel armor, a little better than this armor is a hybrid armor made of mutant beast bones or fur made of steel, but this armor is very expensive, not something that ordinary evolutionaries can have, let alone those special rune armor.

It is estimated that the entire base of rune armor will not add up to more than twenty sets, which shows that it is precious, but this preciousness also represents a strong defensive power.

His knife made from mutant beast bones was good, but it wasn't easy to survive.

Things didn't go beyond Qin Chuan's expectations.

I saw an unusually loud cry in the sky.

Then hundreds of mutated flying beasts suddenly fell from the dark cloud, attacking the man's direction like lightning.

Qin Chuan's pupils shrank slightly.

Second-Order Mutant Flying Beast.

Second-order mutant sparrows to be exact.

The kind of mutant sparrow that likes to devour people's blood.

It's a mutated flying beast that's as fast as lightning and aggressive.

The soldiers inside the bunker noticed the scene.

Quickly turned the gun and launched a dense attack on that place, and at the same time, the door of the modified truck on the ground that had not moved was suddenly opened, and five soldiers carrying bazookas quickly determined the target.

With a bang.

The bazooka was sent out quickly.

In its direction is the place where the unusually loud cry is emanating.

"I see!"

"The man was nothing more than a primer, deliberately exposed, just to attract the attention of those guys in the sky."

Boom! Boom!

Explosions rang out.

The mutant flying beast in that place fell to the ground with a snort of flames like dumplings, and a large gap appeared in the space of that place in an instant.

But in an instant, it was densely covered by those mutated flying beasts.

"Didn't get killed!"

Qin Chuan muttered to himself at the corner of his mouth.
