What appeared behind the two of them was a group of long-overdue Praetorian Guard aliens.

The Courier Alien has a slender body, which is more suitable for stealth and sneak attacks.

The drone xenomorph is slightly larger, and has more power and defense than the courier xenomorph, and may not be better than the courier in street fighting.

As for most Praetorian Aliens, they are not suitable for stealth sneak attacks, after all, the size is there, unless the enemy is blind.

After the courier army and the drone alien stealth sneak attack plan was aborted, it was completely exposed, and the Praetorian Alien began to move from the back of the formation to the front, ready to start attacking.

The first team of guards to appear was the war crocodile alien - the leader was the behemoth that Yunhai got from the parasitic biochemical monsters in Huaxia City A, and behind them was a group of crocodile aliens that had just been born from the crocodile island off the coast of the United States.

They are about six or seven meters long from the top of their heads to the tips of their tails, and their bodies are covered with hard bone plates and scales, and they move like tanks at a rapid pace.

Passing by the sea of clouds, those war crocodile aliens that had already entered the maximum speed did not slow down, and directly rushed towards the large number of fortress buildings.

The increasingly sparse artillery fire, occasionally exploding around them, rolled over and stood up again, and continued to run.

Some of the unlucky ones are directly hit by artillery fire, and unless they are killed on the spot, they will also struggle to rush to the target.

At a distance of hundreds of meters, hundreds of war crocodile aliens rushed over in less than a minute.

The body slammed into the building. Or the thick coccyx swung violently, and the fortresses, which were strong enough to withstand the bombardment of ordinary artillery, were torn apart with a "boom".

10,000 fortress-like buildings. After hundreds of war crocodile aliens rushed away, it turned into a ruin.

Twisted artillery, broken buildings everywhere.

Including the crimson blood seeping from the cracks in the masonry, and the screams of pain.

"Let's go."

The fortress group on the outskirts of the core area no longer exists under the attack of the couriers and crocodile aliens that were previously airdropped. Yunhai greeted Yunyue, who had opened her eyes.

After walking forward for less than a hundred meters, all of a sudden, Yunhai felt that the hairs on his body stood up.

"There's a problem!"

The thought came to my mind. Without waiting for the sea of clouds to warn, an unusually sharp hissing sound was heard.

Suppressed the roar of the wind, piercing the loud sirens.

At the moment of this roar, the alien army swept past the fortress complex and reached the building in front of the center. But he stopped in his tracks. At the same time, he turned around and fled.

However, it was still too late.

In the honeycomb-like building at the core of the base, dense columns of blue energy light illuminate the entire world.

Each one is the thickness of a baby's arm, soaring out of the dense holes of the "hive", and tens of thousands of pillars of energy light shoot out in all directions from top to bottom with the "hive" building as the center.

Nothing could stop its furious fire, just as no flesh and blood could stop the Xenomorph's footsteps.

Whether it's a messenger or a war crocodile alien, the body is easily pierced.

And that's not all, after the brilliant and blurred pillars of energy light penetrated a large number of alien bodies. It shot out for a kilometer all the way, and I don't know how many buildings it penetrated. How many humans were killed hiding in it, and then they disappeared.

In a short instant, not even a second.

At least three hundred messenger and drone xenomorphs have died, including dozens of war crocodile xenomorphs.

And that's not even a serious injury.

He clenched his fists, the green tendons on his face burst out, and the sea of clouds spread out the spiritual command radially at the same time.

…………

…………

In the "beehive", the interior of the circular building is full of soldiers with uneasy expressions.

In front of them is a seemingly high-tech but foolish operating platform.

As soon as the order is given, they only need to press the red button on the front to complete the emission of high-energy rays.

On the larger platform in the center, sitting or standing, a dozen people stared firmly at the face of the seated woman.

"They're starting to retreat, just after a wave of high-energy rays attacked."

The woman opened her eyes, and she knew better than anyone else what was going on outside, and there was no fear on her face.

"God forbid!"

Almost nine out of ten people breathed a sigh of relief.

"The hive is safe for the time being, but what about the rest of the place?"

A middle-aged white man had a painful look on his face and muttered, "Neither the outpost nor the barracks can stop their tracks, what can the others do?" Before the end of the world, plus these two months, can we only hold the hive of the base that we have worked so hard to run? ”

The others' expressions darkened, and one by one they fell silent.

Everyone knew that he was telling the truth, and the base had suffered too heavy losses in this beast tide attack.

Fortunately, the hardware facilities can be rebuilt, and the building can be rebuilt if it is destroyed, and the factory can be rebuilt if it is not.

However, there are a large number of elite soldiers in the base, including specialists in various fields.

In this swift and terrifying beast tide attack, how many people survived.

No matter how many clones there are, in the professional field, they can't compare to an excellent expert.

At least not now, with the help of alien black technology, the "cloning" technology has made a leap.

But the most critical part of the research on the brain is not something that can be broken through in a short period of time.

"Don't be discouraged, as long as the hive is kept, as long as the underground research institute is kept, I can even assure you in the name of the president that the base will soon be built in full swing."

The woman spoke, cheering everyone on.

Jiang Xin looked at her suspiciously, these people are not the top of the base, but they belong to the backbone, and for a while I don't know where this "S" class superman who often follows the president comes from.

"Genetic agents are already in the works, and our biological scientists assert that everyone has a chance to become superhuman in the near future."

"Human cloning research has also made great progress, combined with our advanced medical technology, we are injured, as long as we don't die on the spot, the puppets cloned from our own genes will provide us with a steady stream of organ support."

"The latest high-energy pistols and rifles have been studied, and only the modified production line is needed to produce them in large quantities. There are also new types of aerospace aircraft, fighter jets, and so on. ”

"Your Excellency also said that in a little while, he will pick a suitable place and set up a manufacturing plant where the starships that you have only seen in the movie novels will be produced."

"All this is not empty words, I ask everyone to be strong and survive this beast tide attack, a bright future is waiting for us to open up."

Maybe she has been by the president's side for a long time, and the woman's words are very infectious and energetic, and at the same time, her expression is unusually firm. (To be continued......)
