Looking at the 10 third-level deathclaws in front of them that were comparable to the realm of gods and demons, everyone really had no other emotions except despair.
This attack from the abyssal plane really broke their expectations time and time again.
However, these people on the field have actually been mentally prepared to die in battle one day after joining the Zhenyuan Guards. Therefore, at this moment, even in the face of such a desperate situation, the morale of the team remains the same.
without crashing.
Everyone looked at Zheng Yangxu, waiting for him to give orders.
Under everyone's gaze, Zheng Yangxu took a deep breath and ordered: "Ordinary soldiers retreat immediately. All defense facilities are controlled by the AI system. The mecha brigade stays and defends with me!"
Faced with so many mutant zombies, especially those of the second and third levels, ordinary soldiers have no effect at all, so they can evacuate.
But they must stay, at least to delay this batch of mutated zombies.
Especially those second- and third-level mutated zombies. If they are allowed to go out and wreak havoc, then the teams in the medium-sized shelters will probably be annihilated if they encounter them.
Of course, if the delay can't be stopped, then we will all die together. How could their military headquarters not be prepared at all if they have been defending the abyss passage for so many years.
Under this cave, there is a hydrogen bomb with an equivalent of 10 million tons buried. As long as it is detonated, not to mention 10 third-level mutant zombies, even if you add a zero at the end, they will all die.
Of course, so do they.
Therefore, Zheng Yangxu will not reveal this final trump card until the last moment.
However, when everyone on their side was mentally prepared to die, the development of things once again exceeded everyone's expectations.
Because as the abyss passage fluctuated again, a group of quite rare "blood demons" appeared this time.
In fact, many people don't know whether this "blood demon", which is completely condensed from blood, is a mutant zombie.
But no matter what, as long as you know that the opponent is a creature from the abyss plane and must be killed, it is enough.
However, these "blood demons" did not attack them after they came out, and they did not even have any intention of confronting them. Some turned around and ran back, some ran to both sides, and some even burrowed directly into the ground.
Their liquid-like bodies can easily burrow into soil or rocks, and then squeeze them away to quickly form a channel.
In the blink of an eye, more than a dozen passages appeared in this cave.
The rest of the mutated zombies also followed these blood demons and left here along the passage.
Even among the ten third-order "Deathclaws", seven were heading towards the passage.
"No, they are trying to escape! Quickly launch an attack to stop them." Zheng Yangxu's expression changed and he immediately rushed over with thousands of mechas.
When the three third-order deathclaws who were still staying in place saw this scene, they came forward without hesitation.
The rest of the mutated zombies also took action one after another, such as "Giant Arm" and "Iron Armored Corpse", needless to say, they rushed forward directly.
As for those long-range attack mutated zombies, they are not idle either.
The "Spitter" spits out venom in mouthfuls. It does not attack, but uses the venom to first make other mutated zombies enter a violent state to increase its own strength.
In addition, the few "spray zombies" that came out also spit out large clouds of green poisonous mist from their mouths.
Although these green poisonous fogs could not cause any harm to the mecha, they could greatly obstruct the field of vision. The area near the abyss passage was shrouded in thick green fog in the blink of an eye.
The "blood worms" immediately spit out densely packed bloody beetles. When combined with the green poisonous mist, they are simply invisible and can make ordinary mechas extremely fearful.
As for the "Hunter", its figure is covered by these thick green fogs, and it moves forward like a ghost, and the threat level can instantly increase to a higher level.
In addition, mutated zombies are constantly rushing out of the abyss passage. Even if Zheng Yangxu has thousands of mechas, there is not much he can do to the other side for a while.
Moreover, these mutated zombies are not the only ones coming out from the other side, abyss ghouls and petrified spiders are also coming out in a steady stream.
Under the dual blessing of venom and those green poisonous mist, the combat effectiveness of these cannon fodder races cannot be underestimated. As long as dozens of them swarm up, even mechas may be destroyed accidentally.
Faced with this situation, Zheng Yangxu also knew that he could not mess up the situation and could only let the mechas maintain their formation and advance slowly.
But they don't just have mechas here, the automatic cannons in the camp are pouring firepower towards them all the time, killing the abyss ghouls and petrified spiders.
And at this time, those combat robots and attack drones had also entered the scene, and soon continued to suppress the mutated zombies.
However, as more and more mutated zombies rushed out of the abyss passage, this suppression quickly became powerless.
When the number of mutated zombies reaches 500, there is a vague feeling that they are about to be suppressed.
Especially among the mutated zombies coming out of the abyss passage, a second-level existence will appear from time to time.
This kind of mutated zombie, which is comparable to a strong person in the body shaping realm, needs at least a 10-person mecha team to contain it after entering a violent state.
But at this time, the East China Sea Base finally arrived, a huge sky fortress floating less than 100 meters above the ground.
Mechas that had been prepared for a long time jumped down from the armor plate that was opened above, and leaped directly towards the bottom of the pit.
The number of reinforcements in this batch of mechas is not large, only 100, but there are 85 rare-level mechas inside and 15 legendary-level mechas outside.
At the same time, at the bottom of the Sky Fortress, missile silos were opened one after another.
Small missiles flew out from inside and rushed towards the huge dark pit below.
Under the precise control of the AI system, these small missiles made several changes in direction and then accurately flew into the group of mutated zombies.
In addition, countless Falcon fighter jets fly out from this sky fortress. These Falcon fighter jets are equipped with high-power zombie detectors, which can target even mutant zombies on the ground.
As long as their positions are locked, ground-penetrating bombs will be launched immediately to directly attack the mutated zombies underground.
If you can kill them directly, that is of course the best. Even if you can't kill them, you should try to force them to the ground and let the mecha team that arrives later to deal with them.
With the comprehensive counterattack from 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, and there are more than 500 mutant zombies staying in front of the abyss passage to guard.
As for the number of "blood demons" who had already escaped through the channels opened by them, there were as many as 1,000 of them.
It is definitely an extremely huge challenge to get rid of these mutated zombies that have escaped.
Even if they ignore the ordinary mutant zombies and focus all their energy on the second- and third-level mutant zombies, it is not an easy task.
