Eventually, it was discovered.

Tens of thousands of alien attacks, the base where the core forces of the United States are now located, even in sandstorm weather, even if the alien attack is silent and fast, when they are about to bulldoze the third military camp, the sharp siren pierces the roaring wind and explodes in the sky above the base.

Like a plague, the alarms sounded one after another in all areas of the entire base.

"Let's die together!"

The No. 3 military camp went down to the alarm room, listening to the terrifying impact sound outside the door, and when the alien sharp tail blade had pierced the iron door through countless holes, the soldier who sounded the alarm roared in horror and anger, and then pulled the high-energy bomb without hesitation.

In front of him, the huge military camp was completely overwhelmed by the alien army.

"Boom ......"

A violent explosion sounded, and a terrifying storm of energy swept out.

The two drone aliens who were about to break into the door were directly torn to pieces.

The blue energy frenzy is miserable and domineering.

With the underground alarm room as the center, everything was destroyed in a space of almost twenty meters.

At least fifteen xenomorphs were killed instantly, and many more xenomorphs at close range were hit head-on by the energy shockwave, and their tendons were broken and flew upside down.

Unmoved, injured or dead, none of the aliens cared.

Still moving silently like a tide, ignoring the aliens of life, even their own kind or their own lives, they are equally indifferent.

"In this kind of weather, as long as drones and fighter jets can't be lifted into the air. It won't cause a lot of casualties to the aliens. ”

Sharp sirens sounded in his ears from time to time, and his vision was not clear, but he could feel in his mental sense that countless aliens were about to meet him. Yunhai's heart is unusually steady.

"Hiss......"

At this moment, a team of nimble and vigorous drone xenomorphs appeared, led by a black panther xenomorph, but it greeted the sea of clouds with its own short hissing sound.

"Let's go!"

In the spiritual exchange, he said to Yun Yue, and when he heard that the gunshots had already sounded, Yun Hai turned around and ran towards the direction of the underground fortress of the base with the alien striker.

Along the way, from time to time, people pushed open the door in horror and watched.

Almost nothing was seen. They were greeted only by alien clawed fangs.

As the sea of clouds advanced all the way, it was not only the alien army that surged. And the smell of blood.

With the sound of powerful engines, a team of armored vehicles drove up, and I don't know how the driver did it, and the cars with bright lights drove quickly and smoothly down the street.

Slow down slightly. Yun Hai narrowed his eyes behind the windshield lenses.

"Hiss......"

The Panther Xenomorph let out a high-pitched hiss. When it swooped up, countless alien arrows followed.

Gunfire rang out in a hurry, and when several armored vehicles were completely submerged by the aliens' flesh, the headless flies opened fire without a target.

In fact, there is no need for a target at all, and the front of the armored vehicle, whether it is the street or the rooftop, is almost everywhere aliens.

The tail blade could not tear through the steel shell of the armored car, just when the relentless artillery fire had already overturned a dozen aliens. The couriers and drone xenomorphs that had crawled on the armored bodies gave up their attacks and continued to run forward at a rapid pace.

"Whirring ......"

In the fierce wind. Several large black shadows flew down from the sky.

The iron hook-like claws easily pierced through the steel roof, and the Eagle King Xenomorph didn't look like it took much effort at all, and the huge wings rolled up a gust of wind, actually carrying the armored vehicle weighing dozens of tons into the air.

The street that had just been blocked was emptied in an instant, and when he looked up at several armored vehicles that were thrown away by the Eagle King Alien, the sea of clouds continued to move forward from the alien tide.

"Boom Boom Boom Boom ......"

Seeing that he was about to reach the core of the base, suddenly, a barrage of meteors flew furiously in the deafening sound of artillery.

It is not possible to aim in a sandstorm, and in fact it is not necessary to aim.

A dense barrage poured out of the large bunker-like buildings in the central area, and the hundreds of messengers and drone xenomorphs running at the front suddenly fell in large numbers.

Not ordinary bullets, because it's not machine guns or rifles that howl.

Heavy artillery bullets, powerful enough to be withstood by couriers and drone aliens.

"Discovered!"

A large number of aliens, but their advance was almost silent, Yunhai originally planned to approach, send a small number of aliens to sneak into the fortress, and then defeat from the inside, but did not expect that before they were completely close, there was a ruthless and sharp artillery fire covering them.

"Boom!"

There were countless aliens in front of him, and a building in front of him, and when a cannonball exploded into the building around Yunhai, the shock wave and the splashing stones hit him violently.

"Rush them all, I don't believe they can resist."

Yun Yue shook her fist excitedly on the side.

Yun Hai frowned, and before he could speak, he immediately smiled.

Seemingly impregnable fortresses, relentless artillery attacks may be able to hold the ground for a while, but the air is their mortal wound.

Especially on such a night, when the violent wind and sand swept through the sky and the sky, the fighters, including drones, could not rise into the air, and the visibility was almost zero.

Of course, this does not mean that the fortress did not have even a little air defense.

No matter how they discovered the approach of the flying aliens, the barrage, which was much sparser than the ground, began to burst into the air.

The Eagle King Xenomorph who appeared in the sky above the fortress resisted the bullets of the machine cannon with his body as hard as iron.

Gliding down, when the Eagle King alien approached the fortress, a blue pillar of energy light appeared instantly, directly piercing its body.

The body staggered in mid-air, and the Eagle King alien did not fall, but flew diagonally into the air.

Like a dumpling, a large courier alien fell to the ground from its massive airliner-sized body.

"Your orders?"

Under the transparent goggles, Yun Yue's eyes widened as she watched another Eagle King alien drop a large area of aliens, and her beautiful eyes were full of surprise.

"No, I hadn't thought of it yet, it was entirely their own idea."

Watching the dense artillery reduce at a speed visible to the naked eye, Yun Hai responded with a smile.

"I'll go, the airdrops have all come out, how do I think they're smarter than me."

In the spiritual exchange, Yunyue's voice was a little depressed.

"They're smarter than you."

Yun Hai responded with a smile, and the two of them looked back together.

Hiding behind the buildings, a large number of aliens gave way to the streets.

In the distance, messengers and drones parted like a tide, and a group of car-like behemoths rushed over with impunity. (To be continued......)
