I'm invincible since the end of the world

Looking at the 10 third-level "death claws" in front of them, which were comparable to the gods and demons, everyone had no other emotions except despair.

This time, the attack from the abyss plane really broke their expectations again and again.

However, after joining the Zhenyuan Guard, these people in the field had already prepared themselves to die in battle one day. So at this moment, even in the face of such a desperate situation, the morale of the team still did not collapse.

Everyone looked at Zheng Yangxu, waiting for the other party to give orders.

Under the gaze of everyone, Zheng Yangxu took a deep breath and ordered: "Ordinary soldiers retreat immediately, all defense facilities are controlled by the AI ​​system, and the mecha brigade stays and defends with me!"

Facing so many mutant zombies, especially those second- and third-level mutant zombies, ordinary soldiers can't play any role at all, so they can evacuate.

But they have to stay, at least to delay this batch of mutant zombies.

Especially those second- and third-order mutant zombies, if they are allowed to wreak havoc, the teams in the medium-sized shelters will probably be doomed.

Of course, if they can't delay, then they will die together. After guarding the abyss channel for so many years, how could their military department not be prepared at all?

Under this cave, there is a hydrogen bomb with a yield of tens of millions of tons. As long as it is detonated, not to mention 10 third-order mutant zombies, even if there is a zero at the end, they will all die.

Of course, they are the same.

So Zheng Yangxu will not reveal this trump card until the last moment.

However, when everyone on their side has prepared to die, the development of things is beyond everyone's expectations again.

Because as the space of the abyss channel fluctuated, a group of very rare "blood demons" appeared this time.

In fact, many people don't know whether this "blood demon" completely condensed by blood is a mutant zombie.

But no matter what, as long as you know that the other party is a creature from the abyss plane, it is enough to kill it.

However, after these "blood demons" came out, they did not attack them, and did not even have any intention of confrontation. Some turned around and ran back, some ran to the sides, and some went directly into the ground.

Their liquid-like bodies can easily drill into the soil or rocks, and then squeeze them out, quickly forming a passage.

In the blink of an eye, more than a dozen passages appeared in this cave.

The rest of the mutant zombies followed these "blood demons" and left here along the passage.

Even the 10 third-level "death claws", 7 of them walked towards the passage.

"No, they are going to escape! Launch an attack to stop them." Zheng Yangxu's face changed, and he immediately rushed over with the mecha army.

The 3 third-level death claws that were still staying in place saw this scene and came up without hesitation.

The rest of the mutant zombies also took action one after another, such as "giant arms" and "iron armored corpses", of course, needless to say, they rushed up directly.

As for the mutant zombies with long-range attacks, they were not idle either.

The "Spitters" spewed out venom. They did not attack, but used the venom to make other mutant zombies enter a violent state first, thereby increasing their own strength.

In addition, the "spray zombies" that came out also spewed out large clumps of green poisonous fog from their mouths.

Although these green poisonous fogs could not cause any damage to the mechas, they could greatly hinder the vision. The area near the abyss passage was shrouded in green fog in the blink of an eye.

The "bloodworms" immediately spewed out dense blood-colored beetles. With these green poisonous fogs, they were simply elusive, which could make those ordinary mechas very afraid.

As for the "hunters", their figures were covered by these green fogs, and they moved forward like ghosts, and the threat level could be instantly increased to a higher level.

In addition, there are mutant zombies rushing out of the abyss channel. Even though Zheng Yangxu has thousands of mechas, he can't do much to the opponent for a while.

And the other side is not only these mutant zombies, abyss corpse ghosts and petrified spiders are also rushing out continuously.

Under the dual blessing of venom and those green poisonous fog, the combat effectiveness of these cannon fodder races has become not to be underestimated. As long as dozens of them rush forward, even mechas may be destroyed if they are not careful.

Faced with such a situation, Zheng Yangxu also knows that he can't lose his mind. He can only let the mechas maintain the formation and advance slowly.

However, they don't just have mechas here. The automatic artillery in the camp is pouring firepower towards this side all the time, killing the abyss corpse ghosts and petrified spiders.

And at this time, combat robots and attack drones have also entered the field, and soon continued to suppress the mutant zombies.

However, as more and more mutant zombies rushed out of the abyss channel, this suppression quickly became powerless.

When the number of mutant zombies reached 500, the mecha army had a vague feeling of being suppressed.

Especially among these mutant zombies coming out of the abyss channel, a second-level existence would appear from time to time.

This mutant zombie, which is comparable to a strong person in the body shaping realm, needs at least a 10-man mecha team to contain it after entering a violent state.

However, at this time, the East China Sea Base finally arrived. The huge sky fortress was floating less than 100 meters above the ground.

One by one, the mechas that had been ready long ago jumped down from the armored plates opened above and fell directly to the bottom of the deep pit.

The number of mechas that came to reinforce this batch was not large, only 100, but there were 85 rare-level mechas and 15 legendary-level mechas.

At the same time, at the bottom of the sky fortress, missile silos were opened one by one.

Small missiles flew out from them and rushed quickly towards the huge dark pit below.

Under the precise control of the AI ​​system, these small missiles changed direction several times and flew accurately into the mutant zombie group.

In addition, countless Falcon fighters flew out of this sky fortress. These Falcon fighters were equipped with high-power zombie detectors, which could lock even mutant zombies underground.

As long as their positions were locked, they would immediately launch ground-penetrating bombs to directly attack the mutant zombies underground.

If they could be killed directly, that would be the best. Even if they could not be killed, they should be forced to the ground as much as possible and handed over to the mecha team that arrived later.

With the full counterattack of the East China Sea Base, the battlefield situation was quickly reversed.

However, no one felt relaxed, because there were too many mutant zombies coming out of the abyss channel, and there were more than 500 mutant zombies guarding in front of the abyss channel.

As for those who had escaped along the channels opened by those "blood demons", there were as many as 1,000.

It was definitely an extremely huge challenge to get rid of these mutant zombies that had escaped.

Even if they ignore the first-level mutant zombies and focus all their energy on the second- and third-level mutant zombies, it will not be an easy task.
