After half an hour, the two D2s finally made their move. They simultaneously placed the Z-Type on their shoulders into the group of zombies behind them, and then let out a roar as they pounced towards each other.
Other than Zhang Xiaoqiang, no one could see clearly that in the middle of the sea of zombies, there were two zombies that were not much bigger than ants fighting each other. The two sturdy D2s had completely abandoned their human instincts and were fighting each other like wild beasts. They used their claws to claw at each other, and used their teeth to gnaw at each other. They constantly rolled on the ground, as though they were gladiators in the middle of the sea of zombies.
The two D2s were fighting with their lives on the ground. Zhang Xiaoqiang stood at the top of the hill and watched in a daze. He did not know what the zombies were doing. His understanding of the zombies was only at a rough level. To him, the zombies were just a bunch of walking corpses that thirsted for flesh and blood. Even if the Z-Type was able to control hundreds of thousands of zombies out of the city, he would not be too surprised.
But now, the zombie horde's behavior was beyond everyone's expectations. They seemed to have formed a hierarchy, and even had a division of power. The two zombie horde's confrontation was a display of strength, the two Z-Types were negotiating, and now the two powerful D2 zombies were fighting to the death. Was it to prove whose subordinates were stronger?
The two zombies were about the same size, height, and strength. The process of killing each other was boring, but Zhang Xiaoqiang did not feel bored at all. He did not put down his binoculars for even a moment. The zombies were becoming more and more complicated, and Zhang Xiaoqiang wanted to understand them even more. He did not know if the zombies would form tribes or groups in the future. Right now, he wanted to know more about the changes of the zombies, so when the time comes, he would be prepared to defend or escape.
Finally, out of the two D2s, the D2 won. It bit off the neck of the other D2, and although it was also covered in wounds, the unique characteristics of zombies allowed it to still be lively. It picked up the head of its comrade on the ground and let out a roar to vent its emotions. After that, it walked back to the group and presented the head to the Z-type.
The Z-Type let the D2 tear off the head, and poured the brain juice into its mouth. After eating the brain juice, it slowly walked out of the sea of zombies towards the Z-Type that had lost to it. The Z-Type also walked out and stood motionless a hundred meters away.
Zhang Xiaoqiang saw this and felt even more incredulous. The zombies actually ate the brains of their own kind. In his memory, there had never been any zombies that would eat their own kind. Now the Z-Type had broken Zhang Xiaoqiang's understanding. He swallowed his saliva with difficulty, and his hands began to struggle with the binoculars.
He did not dare to think any further. If zombies could survive by eating their own kind, then wouldn't zombies be able to live forever?
Then zombies would forever be the natural enemy of humans, and humans would have to struggle even harder to survive under the claws of zombies.
An ear piercing sound wave came from the sea of zombies. Zhang Xiaoqiang felt his eardrums vibrate, and the super loud sound wave from a few days ago once again entered his brain. The team members standing behind Zhang Xiaoqiang all covered their ears and squatted on the ground, letting out muffled groans.
Zhang Xiaoqiang's location was close to two kilometers away, so this strange noise only made him slightly uncomfortable. He didn't even need to put down the binoculars to cover his ears. He turned around and looked at the team members behind him before continuing to look in the direction of the zombies. The most important thing now was to figure out what the zombies were doing.
The sea of zombies on both sides became chaotic at the same time. The heads of the zombies at the front started to fall one after another, setting off a wave in the sea of zombies. The continuously falling zombies were like pieces of straw being blown away by a strong wind, spreading towards the depths of the sea of zombies. The sound wave that entered Zhang Xiaoqiang's ears was getting louder and louder. The team members behind him could no longer maintain their squatting position, and all knelt on the ground. Their hands held their heads against the ground, and their mouths began to scream.
Zhang Xiaoqiang didn't care about the life or death of his subordinates. The sound wave that could reach here wasn't as loud as that day. The air itself could absorb sound, so he naturally wasn't worried that the sound wave would kill his subordinates. At this moment, his heart was burning with passion. Looking at the group of zombies that kept falling, he couldn't wait for the sound wave to become even more intense.
Zhang Xiaoqiang finally understood why the Z-Type could control so many zombies. It was because of its innate sound wave. As long as the zombies didn't obey it, it could easily kill them. At the same time, it allowed it to control large groups of zombies. Adding on the fact that it could mislead humans, naturally it could also mislead the more simple-minded zombies.
The two Z-type zombies were like two duelists attacking each other with their strongest attacks, and the zombies that fell behind them were just bystanders that were accidentally injured by their attacks.
They did not attack each other for long, following the explosion of one of the Z-Type's heads, the Z-Type that came from J-City emerged victorious.
The remaining Z-Type walked shakily to the side of the dead Z-Type and picked up the corpse to eat. It ate very carefully, not letting go of any bit of meat. When it was eating, the zombies that fell started to stand up. There weren't many zombies that actually died, just the tens of thousands of zombies near the center. Following the regrouping of the zombies, the two sides of the sea of zombies started to merge.
Seeing this, Zhang Xiaoqiang put down the binoculars in his hands. Both sides of the sea of zombies had been subdued by the same Z-Type …..
Old Frank was still leading his subordinates to work, the man-made Eight Trigrams Formation was already in its embryonic form. With the complicated terrain, even a normal human might not be able to walk out of it, not to mention the invisible zombies. Old Frank had put in a lot of effort, the originally flat land and farmlands were now dug out with half a meter deep, two to three meter wide dirt paths.
On the side of the spiderweb-like dirt paths were many man-made mounds, the mounds formed a line to form walls, and the walls formed a huge corridor. At the intersection of the dirt paths, there were many spacious small plazas. These small plazas were all different in size, the bigger ones were a few thousand square meters, while the smaller ones were over a thousand square meters.
These plazas were the original terrain and had not been excavated, but there were many uneven areas that had been filled up. These small plazas were prepared to accommodate the sea of zombies. After passing through the plazas, there were many dirt paths and dirt walls that formed a huge corridor. Every single path was the same, and every single wall and dirt path was not straight.
Looking down from the sky, one would discover that all of the dirt roads and dirt walls had a certain curve. As long as one followed the dirt road, one would unknowingly be led to the wrong direction. The passage was a 7-8 meter wide dirt road. The large dirt road did not have any branches, and both sides were surrounded by dirt walls. If one followed the dirt road all the way forward, the zombies walking on the dirt road would gather in a large plaza.
