The first batch of mutants was just testing the waters, and soon the group of second-level mutants began to act as humanoid stone throwers again, throwing out the second batch of cannon fodder.

Cannon fodder with a strong physique, even if it lands under such circumstances, it can quickly recover its flexible hands and feet after just shaking.

And after the second batch of cannon fodder was thrown, the third batch also followed immediately, and then the continuous cannon fodder was thrown under the wall.

A batch of 10,000 first-level mutants came down, and the battle instantly entered a white-hot level.

Dense machine guns appeared from all corners of the fence, and tracer armor-piercing shells swept through like a torrential rain.

At the beginning, it also caused great damage to these cannon fodder, killing and injuring tens of thousands of mutants in one go.

However, this scene soon ended, because all the mutants in the next place all lay down at the same time.

Then he crept down in the grass and crawled towards the wall.

"Even if you adapt, be flexible, and self-correct."

Seeing this scene, Cai Ruichen said very seriously.

The actions of these mutants are no less than those of formally trained armies, and in terms of coordination, they surpass all armies in the history of mankind.

Because the actions of these mutants are all like marionettes, controlled by the same mind.

This kind of control can make every mutant on the battlefield maintain the most consistent action.

As soon as they lay down, they all lay down, so that all the soldiers who were shooting lost all the enemies at once.

"We can't go on like this. The Level 2 mutants must be killed. ”

The mind is racing. Cai Ruichen looked at the second-level mutants on the Third Ring Road, full of killing intent. The order was decisively given: "Sniper battalion, kill those second-level mutants." ”

Cai Ruichen did not directly use defensive weapons, but let the sniper battalion take action, and the best way to deal with these second-level mutants was the anti-materiel sniper rifles in the hands of these snipers.

The five hundred snipers who were ready, even the observers, all picked up their sniper rifles.

Because such an enemy does not need him to help the sniper at all. Sort the goals.

The unique gunfire of the anti-materiel sniper rifle rang out, and among the tens of thousands of second-level mutants on the Third Ring Road, the heads of hundreds of second-level mutants exploded almost simultaneously.

The western wall, which stretches for six kilometres, is an average distance of one kilometre from Erbil.

And those second-level mutants are lined up in a line on the Third Ring Road, with five thousand in one line and two rows in front and back.

Under the gunfire of anti-materiel sniper rifles, another group of second-level mutants fell in response.

However, the remaining second-level mutants did not have any fear or retreat, and still took those ordinary mutants. It kept on and on and on and fell under the wall.

The action of the sniper battalion is still sniping them, and the damage done by five hundred snipers. It's terrifying.

In just five minutes, more than 4,000 second-level mutants were directly shot in the head.

But the other second-level mutants just didn't move, and even those corpses, there were no mutants to care about.

However, in the past five minutes, these mutants have already thrown one or two hundred thousand ordinary mutants under the wall.

At this time, it seemed that the tactical goal had been accomplished, and the remaining second-level mutants suddenly and quickly grabbed the corpse of their companion, and then retreated to the city as fast as possible, using the building as a cover.

The corpses of more than 4,000 second-level mutants that had just been sniped were all taken away.

Seeing this scene, Cai Ruichen's brows couldn't help frowning, and he still couldn't understand why these mutants were so keen to collect the corpses of those mutants.

Could it be that there is some big boss in there that needs to devour the corpses of these mutants all the time?

This is just a possible guess, and as for what the situation is, Cai Ruichen is not clear.

At this moment, the battle under the wall also began to become fierce.

Nearly 200,000 artillery fires had already reached the edge of the wall, but their arrival was met with the most stubborn resistance.

Beneath the wall, when the mutants crept closer to the wall less than a hundred meters, the bunker group also opened fire.

The bunkers, which were originally placed almost horizontally, have always been hidden under weeds.

The mutants who were crawling close to each other entered the firepower of the bunker group one after another.

And along the way, these mutants have also paid huge casualties.

The 200,000 mutants were concentrated in front of this front that was no more than six kilometers wide, and the density was very high.

A large number of mines have been detonated, and almost the entire wall has been enveloped in smoke.

Soon, a dense fire suddenly appeared in the smoke of gunpowder, and a single jet of a bunker flamethrower with a hundred meters of flame quickly ignited all these mutants who were crawling forward.

On the plain in front of the wall, a large number of weeds also burned at the same time, and the dense flames covered the entire battlefield in an instant.

"Order the artillery group, using white phosphorus incendiary bombs, to attack the front of the coordinate fence and make the fire burn a little more violently. Everyone, all wearing gas masks. After Cai Ruichen saw a large number of burning weeds under the wall, he decisively gave an order.

Immediately, the entire wall, both the soldiers fighting and the survivors who were transporting ammunition, were all wearing gas masks.

The tank killers in the artillery group also replaced the high-explosive bombs with white phosphorus shells for the first time, and the shelling coefficient began to adjust the elements.

Behind the base, a salvo of rockets began to be fired from four 133-mm rocket launchers in the rocket artillery unit.

The prepared white phosphorus warhead instantly covered a distance of 100 to 300 meters in front of the wall and a width of up to 6,000 meters.

Dense flames began to burn in the weeds, covering the creeping mutants in a sea of fire.

However, I have to admire these mutants, even if they are covered in flames, they are all unconscious and continue to move forward.

It wasn't until the fire gradually burned them to char that they died completely.

In just an instant, the entire front of the battlefield was on fire.

In particular, the weeds spread like a burning plain.

The weeds were burning and the smoke was billowing out, soon engulfing the entire city and base.

If you don't wear a gas mask, the toxic gases emitted by the burning of smoke and white phosphorus are enough for everyone to lose their combat effectiveness.

The smoke quickly obscured the sky, and under the wall, where the smoke was covered, you could see the light of the fire that burned from time to time. (To be continued.) )
