Chapter 424

Change before change!

Looking at the 10 third-order dead claws in front of us, we really have no other emotions except despair.

This attack on the abyss plane really broke their expectations again and again.

However, after they joined the Zhenyuan guard, they were ready to die 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, Yang Xu took a deep breath and ordered: "ordinary soldiers retreat immediately, all defense facilities are controlled by AI system, and the mecha brigade will stay with me and defend with me!"

In the face of so many variant zombies, especially the second and third-order variant zombies, ordinary soldiers can't play any role at all, so they can evacuate.

But they had to stay, at least to hold off these mutant zombies.

Especially for the second and third-order zombies, if they are allowed to go out and wreak havoc, those medium-sized shelters will be destroyed.

Of course, if we can't hold off, we'll make it up to the end. How can their military headquarters be unprepared for defending in the abyss passage for so many years.

Under this cave, however, a ten million ton equivalent hydrogen bomb was buried. As long as it was detonated, let alone 10 third-order mutant zombies, even if a zero was added at the back, all of them would die.

Of course, they do the same.

So until the last moment, Zheng Yangxu will not lift this last card.

However, when all of them are ready to die, the development of things is unexpected again.

Because as the abyss passage fluctuated again, this time a group of rather rare "blood demons" appeared.

In fact, many people don't know whether this kind of "blood devil" is a mutant zombie.

But in any case, as long as we know that they are creatures on the abyss plane, we have to kill them.

However, after coming out, these "blood demons" didn't attack them, or even have any intention of confrontation. Some turned around and ran back, some ran to both sides, and some even went straight into the ground.

Their liquid like bodies can easily drill into soil or rock, and then squeeze them apart to form a channel quickly.

In the blink of an eye, there were more than ten channels in this cave.

And the rest of the mutant zombies follow these blood demons one after another and leave here along the passage.

Even seven of the 10 third-order "dead claws" walked towards the passage.

"No, they're going to run! Attack and stop them. " As soon as Zheng Yangxu's face changed, he rushed over with thousands of mecha.

And the three third-order dead claws, who were still staying in the same place, met up without hesitation when they saw this scene.

The rest of the mutant zombies, such as "giant arms" and "armored corpses", went straight up, needless to say.

As for the variant zombies of the far attack type, they are not idle.

"Spitter" spits out the venom. Instead of attacking, it uses the venom to make other mutant zombies into a frenzied state and enhance its own strength.

in addition to these, the "spray zombies" came out of the mouth, and from this mouth they spit out a big green mist.

Although these green fog can not cause any damage to the mecha, it can greatly hinder the vision. The area near the abyss passage is covered by the thick green fog in the blink of an eye.

"Blood bug" immediately spits out dense blood color beetles. If combined with these green poisonous fog, it's just haunting. It can make those ordinary mecha very scared.

As for the "Hunter", under the cover of these green fog, his body moves forward like a ghost, and his threat level can be instantly raised to a higher level.

In addition, there are a steady stream of mutant zombies rushing out of the abyss passage. Even if Zheng Yangxu has thousands of mecha, there is no big way to take the opposite one for a while.

What's more, these mutant zombies are not the only ones coming out of each other. Abyssal corpses and petrified spiders are also pouring out.

With the double blessing of venom and those green poison fog, the combat effectiveness of these cannon fodder races can not be underestimated. As long as dozens of them rush on, even the mecha can be destroyed accidentally.

In the face of such a situation, Zheng Yangxu also understood that he could not disorganize the square inch, but could only let a group of mechas keep the formation advancing slowly.

However, their side is not only mecha. The automatic guns in the camp are pouring fire all the time to kill this abyss ghost and petrified spider.Moreover, at this time, those combat robots and attack drones have entered the field, and soon continue to suppress the mutant zombies.

However, with more and more mutant zombies pouring out of the abyss passage, this suppression quickly became powerless.

When the number of mutant zombies reaches 500, there is a feeling of being suppressed.

In particular, among these variant zombies from the abyss passage, a second-order zombie will appear from time to time.

This kind of variant zombie, which is comparable to the strong one in the plastic environment, needs at least a 10 person mecha team to contain it after it enters the violent state.

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

A machine armor that had been ready for a long time jumped down from the armor plate opened above and flew directly to the bottom of the pit.

There are only 100 of them, but there are 85 rare ones inside and 15 legendary ones outside.

Meanwhile, at the bottom of the sky fortress, missile silos opened.

A small missile flew out of it and rushed to the huge dark pit below.

Under the precise control of the AI system, these small missiles flew into the mutant zombie group after several turns.

In addition, countless Falcon fighters fly out of the sky fortress. These Falcon fighters are equipped with high-power zombie detector, even the mutant zombies in the ground can be locked.

As long as their position is locked, they will immediately launch the burrow bomb to directly attack the mutant zombies underground.

If you can kill them directly, it's best. Even if you can't kill them, you should try your best to force them to the ground and let them be solved by the subsequent mecha team.

With the comprehensive counterattack on the East China Sea base, the battlefield situation was quickly reversed.

But no one will feel relaxed, because there are too many mutant zombies coming out of the abyss passage. There are more than 500 mutant zombies guarding in front of the abyss passage.

As for those "blood demons" who have opened up channels to escape, there are as many as 1000.

It's a huge challenge to get rid of these mutant zombies.

Even if they don't care about the ordinary variant zombies, it's not easy for them to focus all their energy on the second-order and third-order variant zombies.
