The dull sound of sirens was like the whistle of a train, resounding over the base.

Dozens of anti-aircraft guns spewed tongues of fire, blocking the sky above the top of the mountain, and the barrage drove the firelight, like an upside-down meteor, reflecting a large area of the night sky red.

The nine winged blades spread their wings and flew high into the air, trying their best to dodge the bullet frenzy and not shoot it directly.

"Hiss......"

Outside the city, the belated Spider Alien Queen, leading a large army of black and oppressive aliens, finally approached the New Era base.

The giant snout poked out from under the smooth skull, and the Spider Alien Queen let out a high-pitched hiss, spitting out large clouds of white mist.

This roar was like blowing the horn of attack.

In the darkness, the alien army silently poured into the base giant city.

It's not that it's aimless to attack, under the deployment of the Spider Alien Queen, the alien army has staggered its position when it runs.

Five huge alligator gars, five less large war crocodile aliens, ran silently and swiftly towards the city wall along the safe passage indicated by the messenger.

Behind them, more xenomorphs, including couriers, slowed down, and as they rapidly approached the walls, they sped up towards the massive xenomorphs' backs that had lifted up in front of them.

In the thick darkness, when the huge alligator gar rushed violently, the guards on the city wall felt the vibration and hurriedly moved the searchlight to look down.

Just at a glance, the soldiers defending the city were cold, and their expressions were in disbelief.

Under the city wall, a huge figure ten meters long stood up. The bucket-like forelimbs stomped the walls.

More and smaller black shadows used the bodies of these huge creatures as ladders and springboards, and climbed up like lightning.

"Quick. Fire, there are mutated creatures! ”

"Damn the vigilant people, how come they were attacked by monsters and didn't even find out!"

"Fire, fire......"

The screams of panic or anger didn't last long, as more than a dozen panther-shaped xenomorphs bounced off the alligator's alien skull and landed on the city wall as they burst into the fire. The noisy and noisy city walls suddenly fell silent.

The city wall is only fifteen or six meters high, and the alligator gar that stands up is nearly ten meters high.

Parasitized the xenomorph born of the Black Panther host. Standing on the alligator gar's alien skull and bouncing it with the help of strength, only five or six meters high, it was a piece of cake for them.

Corpses were left on the city walls, and dozens of xenomorphs jumped from the high walls. Ignore the commotion coming from the tent area. Ran quickly to the back hill.

"Hiss......"

As if dissatisfied with the speed of the alien, the spider alien queen, who was watching this scene from afar, trembled with a giant kiss and let out another sharp hiss.

"Boom!"

In response to the Spider Alien Queen, there was a deafening shelling.

A pale blue arc of electricity lit up from the corner of the city wall, and the light gradually brightened as if it was trying to compress the energy.

When the blue light finally turned blazing white, I don't know what weapon it was, and a pillar of light as thick as an arm's arm rushed out.

10,000 meters at a glance. The moment that pillar of light hit out, it had already reached the city wall hundreds of meters away.

"Sneer......"

An alligator gar on the far left is alien. The smooth skull was struck by a pillar of light, and a large swath of bone plates, along with the internal tissues, was completely vaporized.

The wound is extremely smooth, and even the sharpest cutting edge is far less.

However, the alligator gar alien still did not fall, and the sharp trembling kiss showed what kind of pain it was suffering, but it still stood up and lay firmly on the city wall, still trampled on its body by the alien army, and quickly rushed into the city.

These are aliens, it's not that they don't know what pain is, it's just that they don't get swayed by the negative emotions of pain and fear.

Survive, kill, and fulfill the orders of the queen and the master, and for this, the messenger or the janissary will ignore everything, and will firmly carry out and complete.

"Hiss ......"

I don't know if it was a high-tech new concept weapon laser cannon, the spider alien queen was still annoyed by this sudden sharp shot, and the person stood up and let out a sharp hiss.

"Whoosh ......"

Receiving a new order, the five Venom Xenomorphs and the three drone Xenomorphs ran down the city wall towards the laser cannon that had begun to compress energy again.

"Fire, fire!"

Heavy machine guns from all directions of the mountain opened fire fiercely, and the flying fire in the night was slanted on all sides, bright and terrifying.

"What are you doing in a daze, you can't let them rush up! Whoever doesn't fire again, I'll shoot him! ”

In a military bunker in the middle of the mountain, a lieutenant general in command saw that only heavy machine gun fire had been fired, and not a single shell had been fired, and his forehead was covered with beads of sweat, and he roared hoarsely in the communications equipment.

"Boom!"

He was greeted by a violent explosion, but it was not from one of the cannons.

On the city wall, the few laser cannons in the entire base exploded violently when they fired a second laser beam.

Uncontrollable blue arcs bloomed in the night sky like fireworks and silver flowers, poignant and spectacular.

At the same time, several tanks that drove out of the barracks of the 3rd District, roaring and before they even turned around, they were knocked over by several huge bodies, and the tracks turned wildly, completely losing their combat effectiveness.

The explosion of laser cannons, the explosion of tank after tank, including the terrible screams that rang out from time to time......

All this made those gunners wake up, even if the searchlights that strafed everywhere in the base couldn't lock on to the black figures, under the guidance of the superpowered person in the communication equipment, they opened fire violently.

Howitzers, cannons, infantry guns, mortars and even rocket artillery, as well as electromagnetic cannons and laser cannons that are charged and fired from time to time, completely light up the entire sky from the bunkers in various parts of the mountain.

"No, they can't hold it, they are too good at terrain, and the artillery and bullets are almost completely bombarded, killing their own people far more than the enemy. Commander, give the order for the cyborg warriors to attack! They're already close to Zone 1! ”

In the monitoring room of the General Headquarters of the First District, the panicked screams sounded through the loudspeaker equipment, like a ghostly cry of a hypnotic spirit, causing dozens of high-ranking military personnel in the room to panic and sweat like rain.

"Don't panic, I've already sent out the Biochemical Legion, they will stand in front of the position, with the cooperation of the Awakened, they won't let those monsters rush up."

The sound of gunfire died down, and a calm voice was replaced by the communications equipment.

"Appeal ......"

Qi Jianwen, the commander of the New Era Base, wiped the beads of sweat from his forehead and let out a long breath.

For Qi Jianwen, Chen Gong, who has always been pragmatic, will not lie, since he said that he can hold it, then the unknown mutant creatures will definitely not be able to rush forward.

"Where did these mutated creatures come from? As if districts 1 to 4 didn't exist in their eyes? Just frantically rushing to our side of the first district? ”

The voice of one lieutenant general trembled a little.

No one could answer his question, and all the high-level officials in the monitoring room had the same questions as him. (To be continued......)
