"Da Da Da!"

The machine-gun spewed fury, intertwined with a silvery barrage of bullets and the sound of death, shooting at the mutants who were frantically advancing. But the mutant beasts were fearless, they ran wildly, roared, and rushed to the first line of defense with an indomitable formation.

At this moment, the defense line personnel did not all evacuate.

Because?

Because cover is needed!

Although there are rockets, short-range missiles, artillery in artillery positions, and so on, there will eventually be many fish that slip through the net, and those must be eliminated by the soldiers themselves.

The flamethrower shoots flames up to ten meters long.

This is a weapon used by the base to deal with these mutant beasts, in various experiments, the lethality of this flamethrower to mutant beasts is far greater than that of ordinary guns and ammunition, and this flamethrower also uses some post-cataclysmic technology, the temperature of the flame can reach up to 1,000 degrees Celsius, enough to roast those mutant beasts alive, into coke.

This weapon is very powerful, but there is a disadvantage, that is, the range is short, the duration is not long, to maintain such a high temperature and the length of the flame, the energy required is amazing, and now the base is not able to convert the energy of those crystal nuclei into the energy of flames, using specially processed gasoline.

Snort!

The mutant ants running at the front, as soon as they touched the hot flames, suddenly made a crackling sound like firecrackers, and then curled up together, their bodies slowly blackened, and finally slowly burned.

But this only lasted for a while.

Because of the limited vision of the jet, in the face of the mutant beasts coming from all corners of the world, although he moved quickly, he was still slow, and after a while, he was pounced on the ground by some jumping mutant beasts, and then those mutant ants frantically swarmed up.

A terrible scream suddenly sounded!

The voice was desperate, sad and full of anger.

Within moments, only a pile of bones remained on the ground.

As for the flesh and blood, it has already been devoured.

However, the flamethrowers' attacks greatly hindered the speed of the mutants, allowing some soldiers to exit the line of defense through the tunnel in time.

Yes, it's the tunnel!

The three lines of defense are connected by tunnels.

Retreating from the ground is too dangerous, how can a person's speed outrun those crazy mutant beasts, you must know that those crazy mutant beasts are running fast, it is like a car on the highway, that kind of speed makes them desperate.

Through tunnels, they can be effectively defended.

"All of those classes are dead." Long Yang's complexion was unusually heavy.

Li Yuancheng: "Well, yes, all of them are dead, in that situation, it is difficult to survive, they are all warriors!" ”

"Warriors!" Tian Shan glanced at the mutant beast that was letting out a roar of victory from a distance, and shook his head.

There are no warriors in his heart!

They're just a bunch of idiots.

Tang Fang: "Necessary sacrifices are inevitable, no one can guarantee that they will be able to survive this attack safely, we can only do our best." ”

Hearing their discussion, Qin Chuan didn't care, although those soldiers were all dead, but it proved one thing, that is, the huge performance of that kind of weapon, if you stand on the city wall and use this kind of attack against the mutant beasts below with your high-altitude advantage, you will definitely be able to cause huge damage to these mutant beasts.

Presumably they understand this, too.

The military is experimenting.

Experimenting with which method is more effective against mutant beasts, it is clear that at this stage, this flamethrower is a good method.

"They're coming!"

Qin Chuan's words interrupted their conversation.

Everyone looked at the past, only to see that the mutant beasts that had captured the first line of defense did not stop advancing, they rushed forward quickly, and through the telescope they could clearly see that the groups of mutant beasts let out angry roars, braving the attack of artillery fire, advancing frantically.

Bang bang bang!

Shells fell into their camp.

Every shell is capable of inflicting huge casualties on them.

In particular, the 100-millimeter large-caliber cannon unique to the base, every time the cannon goes down, there are dead and wounded all around, and there are vacuum areas one after another.

A hundred millimeter caliber is already the largest caliber that the base has, and as for the cannon of a larger caliber, that is not what their base is capable of.

Boom!

The earth trembled.

Dust rises high.

Smoke fills the space.

Qin Chuan secretly said that if there were enough cannonballs in the base, it was estimated that there would be no need to be afraid of these mutant beasts, and only by relying on the cannonballs would be able to completely destroy these mutant beasts, even if it was a fourth-order, it would not be able to withstand the bombardment of a hundred-millimeter cannon.

It's a pity that there are not many such cannons, there are only five such cannons in total, and there are not many shells, a total of fifty cannons. As for the cannon of other calibers, the power was much less, Qin Chuan even saw a cannonball go down and blast a huge mutant beast away, but after it landed, the mutant beast let out an even more angry roar and moved forward even more frantically.

This kind of mutant beast is generally a mutant beast around the fourth order and mainly defensive.

"Fifteen minutes!"

"What fifteen minutes?" Li Yuancheng asked.

Qin Chuan said: "It only takes fifteen minutes for those mutant beasts to come to our second line of defense. “

When everyone heard this, their faces sank.

But there is no fear of it.

At this time, Xu Qing walked over.

Qin Chuan asked, "How many shells do we have for our artillery!" ”

When Xu Qing heard this, she frowned and said, "It's not optimistic, with the current attack frequency, it can sustain this kind of firepower attack for up to three hours." ”

After hearing this, even Qin Chuan's face darkened, three hours, it is impossible to eliminate those devils, because from the beginning to the present, even those cannon fodder have not been eliminated, the first line of defense is lost, from the time the fire is now, it is only half an hour.

Tayama: "This is the worst news I've ever heard. ”

Xu Qing said: "I have studied with some generals in the General Staff Department, and this second line of defense cannot be held at all according to the enemy's attack position, so I decided to snipe here for a while, and give the personnel of the third line of defense a little more time to prepare, that is, to prepare to withdraw from this defensive line." “

"We're going to fight them to the death on the third line of defense."

Qin Chuan nodded.

For their decision, Qin Chuan will not do anything deliberately, Qin Chuan has enough self-confidence, with his own strength, no matter what happens, the ability to protect himself is still there.

Xu Qing picked up the telescope and watched the situation ahead with Qin Chuan.

"It's a crazy time."

Qin Chuan smiled when he heard this.

But in my heart, I agree, this is indeed a crazy era. 、

But, yes, this is also a colorful era.

It's just a different form in front of everyone.

"What kind of mutant beast is that!"

Xu Qing exclaimed.

Qin Chuan frowned slightly, and then looked over with a telescope.

I saw huge dirt bags appear on the ground, and those dirt bags were moving rapidly.

Laugh at!

A large, hideous head burst out of the ground, then crashed into the ground at one point, eventually forming a huge dirt bag at the same time.

What bugs! It was so large, twenty meters long, with a bucket of water and huge mouthparts, covered with fine and sharp teeth. ”

Qin Chuan said: "If I'm not mistaken, it should be a mutant earthworm!" ”

"Mutant earthworms?"

"How is that possible?"

I have also encountered mutant earthworms in the wild before, but those things are not as huge as this, and at the same time, they do not have such huge mouthparts, Tian Shan shook his head, the first one did not believe it, he was also very familiar with mutant beasts, after all, he also often wandered in the wild and often hunted mutant beasts.

"Believe it or not."

"Captain, tell me about it."

Qin Chuan said: "The mutant earthworms you usually encounter are different from these, these are the mutant earthworms that have devoured the crystal nucleus of the mutant beast, due to the energy of the crystal nucleus, they have mutated and become what they are now. ”

Not only can humans absorb the energy of crystal nuclei, but those crystal nuclei are also extremely precious to mutant beasts, and they will also devour some of the energy of crystal nuclei to evolve.

"I guess these mutant earthworms may have devoured some special energy crystal nuclei to become like this."

"Call the Pyro"

"Why?"

Qin Chuan said: "Flames have great lethality to these guys. ”

Xu Qing nodded.

"It's coming!"

Fire!

A burst of machine gun rage.

The battle that had just stopped, a moment later, was frenzied again, and at this time, some soldiers were running frantically in the tunnel, they were the survivors of the first line of defense, and after being ordered to retreat, they continued to come to support the second line of defense.

The reason why they are still in the tunnel is because their speed is far inferior to that of the mutant beasts, and when it was first built, in order to hurry, they did not take into account the problem of vehicles, so they could only run wildly in this tunnel with their legs.
