This sudden change allowed the leading Blackstone pilot to survive, but no one could be happy. It seemed as if something terrible was coming, and the depressing atmosphere made everyone feel panicked.

"Alert! A large number of biological signal reactions have been found, and the model has been confirmed to be the ne-3 variant of the biological weapon and the is-1 variant."

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

In the surveillance screen, two mechas were guarding the alloy gate at another entrance on the first floor. As the ground continued to vibrate, there was a sudden violent collision sound, layered like ocean waves, up to 20 meters thick.

The entire centimeter alloy door began to deform after being hit, and there were harsh sounds of countless sharp objects rubbing against metal.

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

The two Blackstone pilots were obviously a little nervous. They controlled the mecha and started to retreat slowly while raising their assault rifles.

The sound of metal twisting and tearing became clearer and clearer. A crack finally appeared in the alloy door under the constant collision, and countless sharp claws and limbs were tearing inwards through the cracked door, seeming to want to escape from the narrow door.

Squeeze in through the gap.

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

Bang bang bang bang!

The entire central control hall could hear the blast of gunfire through the monitors. Metal storms like rain shot into the gaps, torn flesh and blood splashed everywhere, and the entire passage seemed to be splashed with a layer of red paint.

, colorful intestines and organs were also sputtered all over the floor.

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

What they faced was not humans or mechas, but biological weapons that had multiplied and mutated for countless generations in this hellish place. They were not afraid of death, and they thirsted for flesh and blood due to their instinctive tendency.

Therefore, not only did these firepower fail to suppress the situation, the monsters outside became even more violent under the stimulation of blood.

What's even more deadly is that because the destructive power of the mecha assault rifle's explosive shells is too great, the gap that was already torn open by the alloy door was blasted into a larger gap.

In addition, what no one expected was that after the blood spattered, it began to corrode everything it touched like strong acid. The originally thick alloy door suddenly became like ice and snow under the sun.

It gradually dissolved, and oozing green smoke kept coming out.

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

In the narrow passage, the two mechas had immediately switched to crawler mode. They fired with their legs, but the speed of the bullets could not keep up with the speed of the monsters.

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

Finally, with a heart-wrenching tearing sound, the two Blackstone mechas were finally engulfed by the black wave. Broken mechanical parts were torn apart and thrown away, eventually splattering with blood.

And more mutated biological weapons submerged past the two shrinking black masses and rushed toward the lower part of the research base.

They smelled the fragrance of fresh flesh and blood.

Not only the entrance to the passage, but also the main entrance that was destroyed by Shi Chen and the others was also flooded with black tide! It was like the god of death descending from the sky.

Seeing those fearless monsters pouring into the Void Research Institute like a tide, Shi Chen's face was twitching. He couldn't even count their specific number. God knows how they have managed to survive in such a barren state over the past thousand years.

The desolate place breeds such terrifying numbers.

Now it has become a luxury to want to escape from the front. No pilot can successfully reach the other side in such a sea of ​​death.

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

Although the ground below has become Suye Hongtu's home ground. There are hundreds of mechas and hundreds of well-trained Blackstone soldiers, but compared with the torrent pouring in from above the research institute at this moment, it can only be two evils.

Whichever is easier.

While shouting these words, he inserted a heavy howitzer into the launcher of the assault rifle and pulled the trigger.

Liya did not hesitate, and finally took a deep look at the cruel picture on the monitor, and rushed out of the central control hall with Shi Chen.

The heavy-duty mecha grenade flew out with an unusual speed, piercing the dark passage in an instant and falling into the group of black stone mechas that had not yet recovered.

What followed was an earth-shattering explosion. A huge fireball rose into the sky. Under the shock wave, the entire passageway began to deform, collapse, and extend like a sand building.

The metal wall connected to the laboratory melted directly under the high temperature, spraying out flames and melting the experimental equipment that was priceless in the earth's era into the sea of ​​fire.

Shi Chen and the others were still four to five hundred meters away from the explosion site, but the image on the light screen had been somewhat distorted by the blazing high temperature.

He couldn't see the fate of the small group of Blackstone soldiers at the entrance of the passage, but under such a powerful blow in such a small place, and because they were distracted and failed to make an evasive defense, it was bound to be a disaster.

From the camera, 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 shuddering under such a high-yield grenade, and his expression did not waver at all. To a certain extent, the war between him and Su Yehongtu had already begun.

These soldiers have no grudge against him, but the moment they step onto the battlefield as soldiers, there are no innocent people. They need to fulfill their responsibilities as soldiers and obey orders, and they are also prepared to die at any time, just like the first time that year.

Just like Shi Chen who stepped onto the battlefield of Sudake.

However, this is only a small group of Guards brought by Su Yehongtu this time, and this loss is just a drop in the bucket.

However, the pilots of the Blackstone Military Region also had the highest military quality. After the initial panic of being attacked, the Blackstone troops reorganized.

Judging from the layout, although Blackstone was prepared, he obviously did not expect that Shi Chen, who was obviously at an absolute disadvantage in terms of military strength, would choose to attack first, resulting in heavy losses in an instant.

But Blackstone's reaction speed was also excellent. The surviving personnel quickly organized themselves, and the follow-up covering troops also rushed from the hiding spots scattered throughout this layer, and used the flank passages to outflank Shi Chen and the others.

All Blackstone's soldiers began to act according to the predetermined plan, busy but not chaotic, without any panic caused by death.

At the same time, the frontal troops immediately fled towards the laboratories on both sides. In just an instant, various grenades, magnetic blast bombs, and even airborne artillery gave Shi Chen and others a sharp counterattack.

The shoulder-mounted artillery roared continuously in the originally quiet Void Research Institute. Everything next to the two mechas controlled by Shi Chen and the others exploded into pieces. The entire light screen was constantly shaking, and then cracks appeared. This should be caused by

The shrapnel sliced ​​into the compound eye.

The two mechas were constantly moving in a zigzag pattern on this floor. Relying on Xiaochu's ballistic warning and the control of their ace pilot, they were able to predict the enemy first. Explosions and smoke became their excellent weapons.

cover.

They will never stay in the same place for too long. The sky is full of shells passing by. After moving several times in succession, the most dangerous heavy firepower bombardment has finally passed. Occasionally, there will be one or two heavy artillery shells or grenades.

Fly here.

What Shi Chen and the others were waiting for was this opportunity. The number of mecha's heavy-loaded cannonballs was generally not too many, but the destructive power in a small area was terrifyingly high.

Shi Chen and Liya controlled the heavy mechas but moved nimbly through the flames and smoke. Occasionally they would flash past the ruins of buildings on the roadside, and sometimes there would be one or two Blackstone soldiers with rocket launchers on their shoulders lurking.

Facing such a fearless warrior, Shi Chen would usually pull out the high-energy particle shock blade behind his shoulder blade, silently ending the battle that had not yet begun.

Being cut by this weapon, you won't feel too much pain until you die. This is Shi Chen's only respect for these black stone soldiers.

When two ace pilots appeared at the same time in such a small area that it was difficult to completely set up their formation, it was an overwhelming horrific massacre.

Facing the soaring death rate, the mecha who was obviously the commander still waved the high-energy particle shock blade in his hand and shouted coldly: "Attack!!"

In the smoke, a powerful explosive bomb modified by Liya passed through the barrier of space and directly hit the external armor on the chest of the mecha. A fiery red fireball instantly enveloped the entire mecha.

.

When the airflow and flames of the explosion passed, the mecha was still standing upright, but the armor on its chest was obviously red and dented, and it remained motionless forever.

"Captain!" An exclamation came from the Blackstone Legion's communicator.

Looking at the motionless mecha, another second-order deputy took over the command. Seeing that the heavy firepower was unable to hit the opponent, he actually ordered to throw away these long-range weapons, and all pulled out high-powered weapons.

The particle shock blades rushed toward Shi Chen and the others like a suicide squad.

It's not that the ace pilots can't be killed, so they plan to kill them with human lives!

This is the horror of the Blackstone Legion.

Shi Chen looked at these Black Stone soldiers who were also fearless of death, and an inexplicable sadness suddenly emerged in his heart.

Countless human-eating monsters have swarmed above the Void Laboratory, but they at the bottom have to choose to kill each other due to various reasons.

He inserted the assault rifle back into his waist, drew out his long blade, and rushed like a leopard into the group of mechas coming forward.
