"It's coming!"

In the face of these "survivors" who suddenly burst out with amazing speed, even not inferior to lickers, and frantically rushed towards the wall and side door, Chen Yifan and the others changed their expressions drastically, and immediately pulled the trigger and shot at those crazy survivors.

However, what is unbelievable is that these ordinary-looking survivors seem to have extremely terrifying strength and physique, even in the face of large-caliber rifle and heavy machine gun fire, or even hit the head and other vital points, they cannot completely tear them apart, at most leaving bullet holes of different sizes, or penetrating, or staying in the body of the bullet, only the powerful impact contained in the bullet makes them slow down slightly.

But that doesn't stop them!

What's even more bizarre is that the vitality of these "monsters" seems to be more terrifying than that of zombies, so even if they pierce their heads, they do not fall, but continue to charge towards the wall, and there is not much blood flowing out of the wounds, but instead gushing out not small and broken, like maggots, but the whole body is pitch black.

"How is that possible!"

Seeing this scene, everyone on the wall was stunned.

They really couldn't understand what the origin of these things was, and how difficult they were.

At the same time, in just a few seconds, these survivors who seemed to have immortal bodies also rushed out of a distance of tens of meters, and there were only thirty meters left from the city wall!

Know!

Know!

Know!

But just as these survivors approached the wall thirty meters, Chen Yifan even wanted to order the rocket soldiers and heavy artillery to shoot, a burst of fierce and piercing, like a cicada's chirping, but a more sharp cry suddenly sounded from the wall.

And with the sound of this sharp cicada, those survivors who were not afraid of bullets before seemed to have encountered a nemesis, their faces showed pain and fear, and at the same time, the speed dropped suddenly, and even a large number of black worms began to pour out of their eyes, ears, mouths, noses, and wounds, and then crawled into the distance, as if they wanted to escape from the wall.

Even the middle-aged man who rushed to the front, with his hands stretching out countless vines, was like a heavy blow at this moment, and he fell to the ground fiercely, and those vines also fell to the ground!

The offensive of these guys was blocked like this!

"It's ......"

Seeing this scene, Chen Yifan and the others were stunned for a moment, and then they all moved their eyes to the white jade cicada that was placed by the masked woman in various places around their walls a few days earlier, like a white jade carving.

They remembered that when Boss Huang and the degenerate instructor came to place these white jade cicadas with the masked woman, they didn't explain to them what the origin was, they only told them that if these white jade cicadas suddenly chirped, it meant that there was a big enemy attacking, and they must be notified.

It's just that these white jade cicadas have been motionless for the past few days, and they don't look like living creatures at all, so they have almost forgotten these things, but they didn't expect these white jade cicadas to suddenly scream at this moment, and they seem to have a strong ability to restrain these strange people.

What Chen Yifan didn't know was that these white jade cicadas were the "White Cicada Gu" refined by Xia Die specifically for early warning and against the black seedling vein poisonous Gu, this kind of white cicada Gu can make a sharp cry when the Gu worm enters within thirty meters, one is an early warning, and the other is that this kind of cry has a strong restraint ability for ordinary Gu worms, and can torso them, so that they dare not approach.

The so-called autumn wind is not moving, and the cicada feels like this......

"On the incendiary/bullet, flamethrower!"

However, although he was shocked in his heart, Chen Yifan was also a battle-hardened person, so he quickly calmed down and shouted at his subordinates.

"Yes!"

Hearing Chen Yifan's words, the soldiers on the wall also took action, turning the bullets of the heavy machine gun into high-explosive incendiary/shells, and at the same time letting dozens of soldiers with flamethrowers come forward and fire fiercely at the soldiers who were already less than thirty meters away from the wall!

In addition to this, the other soldiers also took out the flasks and incendiary bombs that had been prepared and threw them at the survivors on the wall.

Boom Boom Boom!

The next moment, with a fierce roar, the two hundred survivors were also enveloped in a sea of fire in a terrible scream, and then burned violently.

Facts have proved that the flames do have a very good effect on these "corpse people" who have been fully controlled by Gu worms, coupled with the deterrence of the white jade cicada, at this moment, these survivors have lost their ability to resist, and they have been burned into charcoal by the high-temperature flames, and even the Gu worms in their bodies have not been spared!

Boom Boom!

At the same time, a violent vibration suddenly came from under the ground not far from the wall, and then a large area of the ground collapsed strangely, revealing the broken tunnels under the ground, as well as countless mutated creatures and zombies in the tunnels!

In addition, there are a large number of earthy yellow beetles in the collapsed tunnel, which are rapidly eating away at the soil, as if there is a bottomless pit in the stomach, and continue to spread the tunnel forward.

"What?"

Seeing this scene, Chen Yifan's heart was shocked.

Although Qiu Laosi had been prepared as early as when the wall was built, the wall was several meters deep underground, but if it wasn't for the sudden collapse of this tunnel, I am afraid that it would not be long before these zombies and mutated creatures would bypass the wall under the leadership of those yellow beetles and burrow into the mountain from the ground!

At that time, if such a large number of zombies and mutated creatures suddenly poured out from behind them, even if they could not attack this first line of defense, they would inevitably bring them huge troubles and casualties!

"Fire, fire!"

"The marked position is 150 meters, the firing area is seven areas, all heavy artillery, mortars, and rocketeers are attacking in full force!"

The next moment, Chen Yifan reacted and immediately gave an order.

Boom Boom Boom!

With Chen Yifan's order, the rocketeers on the wall, and the mortar team and heavy artillery team behind the wall also opened fire, and in an instant, countless rockets/projectiles fell from the sky like a torrential rain, falling into the tunnel exposed by the collapse, and finally exploded, setting off a flood of flames, completely devouring a large number of zombies and mutated creatures in the tunnel.

"Damn it!"

On the other side, seeing this scene, Amna, who was hiding in the shadows, also changed his face.

He guessed that Xia Die might use the White Cicada Gu to take precautions, so he didn't have much hope for the two hundred corpses, but while sending those corpses to attract the attention of everyone on the wall, he also sent the Soil Eating Gu to dig from the ground, hoping to hide from the people on the wall, and finally pass through the wall and attack from behind, so as to break through this line of defense in one fell swoop.

But he never expected that although this Zhaoshan Mountain seemed ordinary, for some reason, a large amount of extremely hard granite appeared everywhere around the wall of the first line of defense, especially under the main gate, which greatly slowed down the progress of these earth-eating Gu excavation operations, so that he could not keep up with those corpses to break through in the first place.

And what made him even more incomprehensible was that it stands to reason that the tunnels excavated by the Soil Eating Gu should be quite stable, but why did these tunnels suddenly collapse at the most critical moment, exposing the insect corpses and insect beasts that were hiding underground and controlled by the Three Corpse Insects and Ten Thousand Soul Insects, and finally caused his plan to completely collapse!

Why is that?

This is completely counterintuitive!

Of course, Amna didn't know that since Qiu Laosi sacrificed himself and integrated into the entire Zhaoshan, Zhaoshan had "spirituality", which can be said to be protected by Qiu Laosi's underworldly will, but anyone who is hostile to everyone on Zhaoshan will encounter a lot of inconvenience after going up the mountain, and even this kind of tunnel collapse will occur.

As for those granites, they were just created by Qiu Laosi when he used his earth skills to cooperate with his own abilities when building the wall, just to prevent any monsters from digging and breaking through from the ground one day, but he didn't expect it to be used on Amna and others at this moment.

"That's it, since Plan 1 has failed, then we can only use Plan 2!"

However, Amna was also a gloomy person, so although he was angry at the moment, he quickly calmed down, and then took a deep breath and gave a new order to his subordinates through the sound transmission Gu.
