Half an hour passed, and the two D2s moved, and at the same time they put the Z-shaped zombie on their shoulders to the group of corpses behind them, and then let out a howl and pounced on each other at the same time.

Except for Zhang Xiaoqiang, no one could see clearly that there were two zombies that looked not much bigger than ants fighting in the open space in the middle of the sea of corpses, and the two sturdy D2 zombies completely abandoned their human instincts to fight each other like beasts in the open space, they grabbed each other with their claws, gnawed each other with their teeth, and they kept rolling on the ground, like a gladiator fighting in the middle of the sea of corpses.

The two D2 are fighting to the death below, Zhang Xiaoqiang stood on the top of the hill and looked stupid, he didn't know what the zombies below were doing, his understanding of zombies only stayed on the rough hierarchy, for him, zombies were a group of walking corpses who were full of thirst for flesh and blood, even if the Z-type zombies controlled hundreds of thousands of zombies out of the city, he was not too surprised.

But now the zombie sea is very unexpected, they seem to have a constant class, and even have a division of power, the two corpse seas are fighting each other to show their strength, and the two Z-type zombies are negotiating, and now the two powerful D2 zombies are fighting to the death, just to prove whose subordinates are stronger?

The process of two zombies of similar size, size, and physical strength fighting each other is boring, but Zhang Xiaoqiang does not feel bored, the telescope in his hand has not been put down for a moment, the zombies are becoming more and more complicated now, Zhang Xiaoqiang has to understand more, he doesn't know whether the zombies will form a tribe to form a collective in the future, and now he just wants to know more about the changes of some zombies, and there is a certain amount of preparation for whether to stick or flee when the time comes.

Eventually, the two D2s ended in the victory of one D2, it broke the neck of the other and bit its head off, although it was also scarred, but the unique characteristics of the zombie made it still alive, it picked up the head of the same kind that rolled on the ground and let out a wild roar to vent the emotions in its heart, and then it walked back to the team and presented the head to the Z-type zombie.

The Z-type zombie asked D2 to rip off its head, and it slowly shook its body out of the sea of corpses, and faced the Z-type zombie that failed under the opposite side, and the Z-type zombie on the opposite side also walked out and stood still through the 100-meter-long clearing.

Zhang Xiaoqiang felt even more incredible when he saw this, zombies actually ate the brains of the same kind, in his impression that no zombies would eat their own kind, and now the Z-type zombies broke Zhang Xiaoqiang's cognition, he swallowed a mouthful of saliva with difficulty, and his hands holding the telescope began to fight slightly.

He didn't dare to think about it anymore, if zombies could survive by eating their own kind, wouldn't zombies live forever? In that way, zombies will always become the natural enemies of humans, and humans will have to work harder to survive under the minions of zombies?

A piercing sound wave came from the sea of zombies, Zhang Xiaoqiang only felt a shock to his eardrums, like the ultra-high audio of a few days ago came into his mind again, and the team members standing behind Zhang Xiaoqiang all covered their ears and squatted on the ground and snorted.

The place where Zhang Xiaoqiang was nearly two kilometers away from there, so the weird noise this time only made him slightly uncomfortable, and he didn't even need to put down the binoculars to block his ears, he turned around and looked at the team members behind him and continued to look over there, now the top priority is to find out what the zombies over there are just now?

The sea of corpses on both sides was chaotic almost at the same time, and the heads of the zombies in front of them fell one after another, setting off a wave in the sea of corpses, and the zombies that kept falling spread to the depths of the sea of corpses like pieces of straw that were blown by the wind, but the audio sound in Zhang Xiaoqiang's ears became louder and louder, and the team members behind him could no longer maintain a squatting posture and knelt on the ground one after another, holding their heads to the ground with their hands in their hands, and their mouths began to howl miserably.

Zhang Xiaoqiang didn't care about the life or death of his subordinates, the audio that could be transmitted here was not as big as that day, the air itself could absorb the sound, he was naturally not worried that this kind of sound could kill his subordinates, at this moment his heart was hot, looking at the group of corpses that kept falling, he wished that this kind of ultra-high audio would come more violently.

Zhang Xiaoqiang finally knew why the Z-type zombie could control such zombies, that is, relying on its natural sound frequency, as long as there were zombies who did not obey it, it could be easily killed, and at the same time, it could control a large group of zombies, plus it could mislead humans, and naturally it could also mislead zombies with simpler brains.

The two Z-type zombies are like two duelists sending their biggest attack to each other, and the zombies that fall behind them are just the city gate pond fish that were accidentally injured by their attacks.

They didn't attack each other for long, and as the head of a Z-type zombie exploded all at once, the Z-type zombie that came out of J City finally won.

The remaining Z-type zombie staggered to the dead Z zombie and picked up the corpse and ate it, it ate very carefully, not letting go of any bit of residual meat, when he was eating, those fallen zombies began to stand up one after another, there were not many zombies who really died, that is, there were about a dozen rows of tens of thousands near the middle of the open space, and as the zombies regrouped, the sea of corpses on both sides began to merge into one.

Seeing this, Zhang Xiaoqiang put down the telescope in his hand, and now the sea of zombies on both sides is subdued by the same Z-shaped zombie...... The honest man is still busy with his subordinates in the construction, the artificial gossip array has a prototype, the intricate terrain, even a normal human may not be able to come out, let alone an invisible zombie, the honest man has made great efforts, the original flat land and farmland have all been dug out of a half-meter deep, two to three meters wide dirt road.

On the edge of the dirt road that is dense like a spider's web is a pile of artificial mounds, the mounds are connected next to the mound to form a series of earthen walls, the earthen walls form a huge corridor against the earthen wall, and at the intersection of those dirt roads are wide small squares, each of these small squares is different, the large ones are thousands of square meters, and the small ones are thousands of square meters.

These squares are the original terrain has not been dug up, but there are a lot of uneven places that have been artificially filled, these small squares are prepared to accommodate the sea of zombies, across the square is already a large corridor formed by dirt roads and earth walls, each dirt road is the same, and each earth wall and dirt road are not straight.

If you look down from the sky, you will find that all the dirt roads and earth walls have a certain arc, as long as you follow the dirt road, you will be unconsciously led to a large dirt road with a width of seven or eight meters, the large dirt road has no branches, and the two sides are surrounded by the earth wall.
