This sudden change saved the first Blackstone pilot, but no one could be happy, as if something terrible was coming, and the oppressive atmosphere made everyone's hearts panic.

"Alert! A large number of biological signal responses have been discovered, and the models have been confirmed to be the variant of the NE-3 model of the biological weapon and the variant of the IS-1 type. ”

Hearing this, Shi Chen suddenly turned his head and looked at the monitor in the central control hall, and his pupils suddenly shrank.

I saw that in the surveillance screen, two mecha were guarding the alloy gate at the other entrance on the first floor, and with the continuous shaking of the ground, there was a violent collision sound, like waves on top of each other, and the alloy gate with a thickness of 20 cm was all hit and began to deform, and there were countless sharp objects rubbing against the metal The harsh sound came out.

It seems that it is only a matter of time before the alloy door breaks.

The two Blackstone pilots were visibly nervous, and began to slowly retreat while holding their assault rifles in their mechs.

The sound of metal twisting and tearing became clearer and clearer, and a crack finally appeared in the alloy door under the continuous collision, and countless sharp claws and limbs tore inward through the crack in the cracked door, as if trying to squeeze in through the narrow gap.

The two mechs finally couldn't stand this torture from the fear of the unknown and pulled the trigger.

Bang bang!

The entire central control hall could hear the exploding gunfire through the monitor, and the rain-like metal storm shot into the cracks, and the torn flesh and mortar splattered everywhere, and the entire passage seemed to be splashed with a layer of red paint, and the colorful intestines and organs were also splattered all over the ground.

Although the heavy fire suppression had its due effect, they made a fatal mistake.

They are not faced with people, nor mechas, but in this hellish place, there are biological weapons that have multiplied and mutated for countless generations, and they are not afraid of death, and they are instinctively hungry for flesh and blood.

So not only did these fires not play a role in suppression, but the monsters outside became more and more violent under the stimulation of blood.

And even more deadly. Because the destructive power of the mecha assault rifle burst bullet was too great, the gap that had already torn open the alloy door was blasted into a larger gap.

In addition, what everyone didn't expect was that after the blood splattered, it began to corrode everything they were stained with like strong acid, and the originally thick alloy door suddenly gradually dissolved like ice and snow under the sun, and continued to emit oozing green smoke.

This situation did not last long, and the overwhelmed alloy door was finally smashed open by a monster like a black wave behind it, and it collapsed to the ground.

In the narrow passage, the two mechs had already switched to the tracked mode for the first time. The side leg was shot, but the speed of the bullet was no longer able to keep up with the rate at which the monsters pounced.

Those monsters were not afraid of death at all, and just stepped on the broken corpses of their companions and continued to rush forward frantically.

Finally, in a tooth-aching tearing sound, the two Blackstone mechs were finally engulfed by the black wave, and the broken mechanical parts were torn and thrown away, and finally splashed with blood.

More mutant creature weapons drowned past the two shrinking black blobs and rushed towards the lower part of the research base.

They smell the fragrance of fresh flesh.

It's not just the entrance of the passage, the main entrance that was destroyed by Shi Chen. There is also a Kuroshio wave! It's like death descending from the sky.

Seeing those monsters who were not afraid of death pouring into the Void Research Institute like a tide, Shi Chen's face twitched, and he couldn't even count the specific number of them, God knows how many of them have been. How did they multiply in such a barren and inhospitable place?

Now it has become a luxury to want to get out from the front, and no pilot can successfully reach the other side in such a sea of death.

In a brief exchange with Xiao Chuyu in his mind, he shouted to Liya, who was also shocked by this scene, in the communicator: "Escape to the lower floor!" There is a missile launch channel at the bottom of the research institute! Let's go from there! ”

Although the following has become the home of Suyahongtu. There are hundreds of mechs and hundreds of well-trained Blackstone soldiers, but at this moment, compared to the torrent pouring in above the research institute, it can only choose the lesser of two evils.

When shouting this sentence. He slipped a heavy howitzer into the launcher of an assault rifle and pulled the trigger.

Liya didn't hesitate, and finally took a deep look at the cruel picture in the monitor, and rushed out of the central control hall with Shi Chen one after another.

The mecha heavy grenade suddenly roared out at an unusual speed, cutting through the dim passage in an instant, and falling into the group of blackstone mechs that had not yet recovered their senses.

Then there was an earth-shattering explosion, a huge fireball rose into the air, and under the shock wave, the entire passage began to deform, collapse, and extend like a sand-made building.

The metal wall that connected the laboratory melted directly in the heat, spewing flames and merging the priceless experimental equipment placed in the Earth Age into the sea of fire.

Shi Chen and the others were still four or five hundred meters away from the explosion site, but the images on the light screen had been somewhat distorted by the blazing heat.

He couldn't see the fate of the small group of Blackstone soldiers at the entrance of the passage, but under the blow of such a small place and this kind of power, and because he was distracted, he couldn't make a defensive move, so it must be more than lucky.

From the lens, you can see that at the moment of the explosion, countless mecha parts and even the stumps of the Blackstone soldiers flew up with the explosion!

Shi Chen felt the earth's tremor under this high-yield grenade, and his complexion did not fluctuate in the slightest, to some extent, the war between him and Su Yehongtu had begun.

These warriors have no grudge against him, but the moment they step on the battlefield as a soldier, there are no innocent people, they need to fulfill their duties as soldiers and obey orders, and they are also ready to die at any time, just like Shi Chen who first set foot on the battlefield of Sudake.

However, this was only a small squad of the Guards brought by Suyahongtu this time, and this loss was only a drop in the bucket.

However, the pilots of the Blackstone Military Region also possess the highest military qualities, and after the initial panic of being attacked, the Blackstone troops were reorganized.

Judging from the arrangement, although Heishi had already prepared, he obviously did not expect that Shi Chen, who was obviously at an absolute disadvantage in military strength, would choose to attack first, so he suffered heavy losses in an instant.

However, Heishi's reaction speed was also excellent, the survivors quickly organized, and the follow-up covering troops also rushed from the hiding points scattered throughout this level, and outflanked Shi Chen behind them through the passage on the flank.

All Blackstone's soldiers began to act according to the predetermined plan, busy but not chaotic, and did not panic at all because of the death.

At the same time, the frontal troops immediately approached the laboratories on both sides, and in an instant, all kinds of grenades, magnetic storm bombs, and even airborne artillery gave Shi Chen their sharp counterattack.

The shoulder-mounted artillery roared endlessly in the originally quiet Void Research Institute, and everything next to Shi Chen's two mechs exploded into pieces, and the entire light screen was constantly shaking, and then cracks appeared, which should have been slashed by shrapnel.

The two mechs were constantly moving in a zigzag pattern on this floor, relying on Xiao Chu's ballistic warning and the control of their ace pilot, they were always able to anticipate the enemy first, and the explosion and gunpowder smoke became their excellent cover.

They would never stay in the same spot for too long, the air was full of shells, and after several successive shifts, the most dangerous heavy shelling finally passed, and only occasionally one or two heavy artillery shells or grenades flew in.

And Shi Chen and the others are waiting for this opportunity, the number of mecha heavy shells is generally not too much, but the destructive power in a small area is terrifying.

Shi Chen and Ria wielded heavy mechs but moved through the flames and smoke, occasionally flashing through the ruins of buildings on the side of the road, and sometimes lurking one or two Blackstone soldiers with rocket launchers on their shoulders.

In the face of such fearless warriors, Shi Chen generally directly pulled out the high-energy particle concussion blade behind his shoulder blade, silently ending the battle that had not yet begun.

Being cut by this weapon until he dies will not feel too much pain, this is Shi Chen's only respect for these Blackstone soldiers.

The presence of two ace pilots at the same time in such a narrow area that it is difficult to completely set up the formation is an overwhelming horrific massacre.

In the face of the soaring mortality rate, the obviously commander mecha still waved the high-energy particle concussion blade in his hand and shouted coldly: "Attack!!" ”

In the smoke of gunpowder, a high-powered explosive bomb modified by Leah passed through the barrier of space and directly hit the external armor on the chest of the mecha, and a fiery red fireball instantly enveloped the entire mecha.

When the blast and flames passed, the mecha was still standing, but the armor on its chest was visibly red and dented, and it was forever immovable.

"Captain!" There was an exclamation of surprise in the Blackstone Legion's communicator.

Looking at the motionless mecha, another second-order deputy took over the command, and seeing that the heavy firepower could not hit the other party, he actually ordered these long-range weapons to be thrown away, and Qi Qi pulled out the high-energy particle concussion blade, surging towards Shi Chen and them like a death squad.

It's not that ace pilots can't be killed, so they're going to kill them with their lives!

That's the horror of the Blackstone Legion.

Shi Chen looked at these Black Stone soldiers who were also not afraid of death, and an inexplicable sadness suddenly appeared in his heart.

Countless devouring monsters have surged above the Void Laboratory, but at the bottom, they have to choose to kill each other for various reasons.

He reinserted the assault rifle back into his waist, drew his long blade, and rushed like a leopard into the swarm of mechs rushing forward.
