The alien soldiers frantically poured out the firepower of their armors, and those monsters not only did not flinch in the face of the soldiers' frantic strafing, but attacked more fiercely.

One by one, the monsters opened their bloody mouths and let out that deafening roar. The voice was so sharp that it made all the warriors feel their souls tremble.

The warriors wiped out a wave, and then rushed up again, as if the monsters couldn't finish killing.

Soon, some of the fighters' armor energy was depleted, reducing the blockade of this part of the firepower, and the pressure on the other fighters instantly increased.

The monster that had been suppressed in the passage rushed into the hall again. The monsters stared at the warriors in the hall with blood-red eyes.

They seemed to see the delicious food, and then they heard the monsters let out a greedy roar, and then rushed towards the warriors with lightning speed.

"Hive Photon Cannon!"

The second captain yelled, and then immediately put away the heavy pulse cannon, and instantly sacrificed the high-frequency launcher.

Seeing this, the other fighters also reacted quickly. Some throw obstacle mines, while others offer high-frequency transmitters.

Clusters of dazzling golden light curtains swooped down on those monsters at lightning speed, engulfing them all in an instant.

Under the attack of the Hive Photon Cannon, the monsters in the hall were wiped out in an instant.

At this time, the passage was full of monster corpses, which also made the monsters behind them unable to rush up for a while.

Although no monsters rushed up again, the warriors did not dare to relax in the slightest.

The warriors who had run out of energy quickly retreated to the back of the hall, and the warriors who were full of energy immediately made up for it.

After a few minutes, all the warriors' armors were fully charged, and they were all stationed outside the passageway. All the warriors had their eyes fixed on the monster corpse at the entrance of the passage, ready to attack.

But what happened next made the warriors feel very strange, and they didn't know why the monsters didn't move again.

At this moment, the hall was as silent as death. Except for the breathing of the comrades in the channel, I couldn't hear the slightest sound.

And the more quiet it was, the more nervous the alien warriors became. The warriors didn't even dare to catch their breath, their eyes fixed on the entrance of the passage.

This lasted for about five minutes, and after five minutes there was finally movement from below the passage. The movement was more violent than before, as if the earth was shaking.

A moment later, I saw the monster corpses piled up at the mouth of the passage, flying out of the passage like cannonballs. The next moment, a huge gap formed in the pile of corpses.

Then I saw a huge monster rush out. It is five meters tall and about fifteen meters long. It roared wildly with its bloody mouth open, its fangs the size of a child.

Its thick limbs were covered with huge claws as sharp as scimitars, and a tail more than ten meters long behind it kept swinging back and forth, and the surface of the tail was dark and shiny, and it looked like it was made of metal. The end of the tail is like a sharp spear, which makes people feel creepy.

If Lin Yifan was present at this time, he would definitely be able to recognize this monster. Its appearance resembles the biochemical spearhead developed by Queen Ulantis, Hunting.

However, this monster is much larger than Hunting, and its combat power is not the same as Hunting.

Seeing this behemoth, all the warriors couldn't help but shudder.

In just a few moments, all the warriors recovered from their shock. They immediately grabbed their weapons and fired a fierce fire at the behemoth.

Dense beams of pulsing light struck the monster, causing it to let out a series of terrible roars.

Fortunately, this monster is only a replica of Hunting, it does not hunt the hard chitin shell of King Kong.

Under the attack of dense pulsing beams, dozens of huge wounds were blasted out of the body of this huge monster.

It let out a deafening roar as it stared at the alien warriors with its large, red eyes.

Then I saw it slam on all fours, rush at it like lightning, and then raise its sharp claws and wave them at the warriors.

Seeing this, the warriors immediately activated the power system of the warframe and hurriedly dodged to the side.

Although the warriors reacted very quickly and dodged the attacks of its sharp claws, they did not escape its sharp tail.

Some of the warriors were stabbed by its sharp tail, which pierced the thick armor of the armor with its spear-like tail.

I heard the soldiers let out a scream, and blood spurted out along the huge hole. Fortunately, the Ice Phoenix Warframe has a self-rescue system, and some fighters who were not fatal by a single blow were stopped bleeding by the emergency repair liquid.

And at this moment, the sound of ten thousand horses galloping in the passage was heard again. Hearing this, the warriors fell into complete despair.

This huge monster is difficult for them to deal with, and if you add that group of small monsters, none of the warriors will be spared, and all of them will be killed.

And at this critical moment, the gate of the passage suddenly sounded. Then I saw the gate that was ten meters thick slowly falling.

And when the gate fell halfway, it was stuck by the monster corpses on both sides of the passage.

"Captain One, they've found the controller, hurry up and blast the corpse at the entrance of the passage for me!" The second captain yelled.

Hearing the shouts of the second captain, several warriors turned the power of the battle armor to the maximum and bypassed the giant beast in the hall at lightning speed.

Then he picked up the heavy pulse gun in his hand, and blasted at the monster corpse at the entrance of the passage.

After the frantic bombardment of the fighters, the corpses were blown to pulp. Without the corpses in the way, the floodgates began to fall slowly.

And at this time, the little monsters in the passage also rushed to the entrance. They are like locusts, swarming outwards. Many monsters were instantly squeezed into meatloaf under the huge pressure of the gate.

"Fire at the bottom of the gate!" The second captain ordered.

In order to allow the gate to fall smoothly, the soldiers who were responsible for clearing the passage turned on the firepower of their armor to the maximum and bombarded the bottom of the gate wildly.

After several rounds of bombardment, the monster at the gate was finally eliminated and the gate was successfully closed.

However, the crisis was not resolved at this time, and the huge monster saw that the floodgates were closed, and its young beast could not rush out. It was like it was going berserk, and it attacked the fighters even more violently.

The speed of the mad beast was as fast as lightning, and in just a dozen seconds, it caused heavy damage to the alien warriors.

At this time, the first captain also rushed to the hall with people, and when he saw the tragic situation in the hall, the first captain roared angrily.

"Kill this brute for me!"

As he spoke, the captain immediately used the Hive Photon Cannon and launched a fierce attack on the giant beast.

Seeing the death and injury of their comrades, the anger in the hearts of the soldiers who had just arrived was instantly ignited, and one by one, as if they were crazy, they picked up the heavy pulse cannon and fired fiercely.

Under the attack of hundreds of people, the giant beast was also wounded by the bombardment. The wounds all over the body did not make the beast fall, but only made it even more insane.

It dragged its wounded body and charged ferociously towards the alien warriors.

At this moment, I heard a loud roar from the captain: "Hit me in the leg!" ”

Hearing the words of the captain, all the warriors aimed their weapons at the limbs of the giant beast.

Under the fierce attacks, the limbs of the giant beast were quickly blasted out of huge wounds, and after a while, its speed slowed down.

Seeing this, the warriors increased the energy supply of the weapon system, and they vented all their anger on the limbs of the giant beast.

The beast's limbs were severely injured and it was quickly incapacitated. It opened its bloody mouth and roared viciously.

Seeing that the beast was no longer able to move, the warriors all rushed in front of it and attacked its massive head with a fierce attack.

In just a few seconds, the beast's head was blasted to shreds, and it could no longer die.

At this time, the soldiers were also exhausted, and one by one they collapsed to the ground, panting violently.

"Everybody's on orders! Immediately clear one layer of the battlefield and prepare to clear the other floors of the base. The captain commanded.

Although he also wanted to let the soldiers rest for a while, the situation was very critical now, and he did not dare to delay for a while.
