The four of them just converged, a strong high-frequency sound pierced the entire gathering place, countless zombie heads exploded at the same time, brains and various soft tissues erupted from the zombies' ears, nose and mouth, the high-frequency sound made the four people like a lightning strike, shocked them dizzy, almost pierced their eardrums, the audio was too high, such as a chirp in everyone's brains, among several people, Wan Qiang was the most unbearable, lying in the corpse pile, constantly digging on the ground, as if to dig a pit to bury himself.

Xiaobing and Mu Peipei reacted similarly, one sat in the car, the other sat on the ground, his eyes were confused and empty, and he couldn't find focus, only Zhang Xiaoqiang reacted a little better, he expected it before he came, but he didn't expect that the audio of this Z-type zombie was several times that of the X-type zombie he had encountered before, even if he wore earmuffs, he couldn't resist it.

Although he couldn't expel the noise that seemed to sound from the depths of his soul, but he did not completely lose his mobility like several other people, Zhang Xiaoqiang held the trigger of the heavy machine gun, lowered his head to fight against the high sound wave, and the sweat soaked the military uniform in the shortest time, but Zhang Xiaoqiang did not fall, but struggled with the high-frequency sound wave with the greatest willpower, he knew that the Z-type zombie would not keep screaming, at the same time, the lethality of the high-frequency sound wave is indiscriminate, and the lethality of the zombie is higher than that of humans, Zhang Xiaoqiang even hoped that the sound wave would last a little longer.

Zhang Xiaoqiang expected to kill the zombies with the help of the high-frequency sound waves of the Z-type zombies, the Z-type zombies did not disappoint him, countless zombies were like wheat fields torn by the wind, falling one by one, at the bridge when Zhang Xiaoqiang came, the zombies stopped the offensive, standing silently like a group of scarecrows, and the soldiers also broke away from the zombies, covering their ears and kneeling on the ground to suffer.

The volume of high-frequency sound waves is getting higher and higher, like a thousand women with sharp voices screaming at the same time, like the echo of a large passenger plane after it passes overhead, just when Zhang Xiaoqiang's thoughts gradually become confused, the sound waves stopped abruptly.

Zhang Xiaoqiang's brain suddenly relaxed, he raised his head suddenly, and saw the Z-type zombie group three hundred meters away, the lethality of the Z-type zombies is indistinguishable, the zombie sea before them was all emptied, and there was no zombie combat power within a radius of five hundred meters, only the Z-shaped zombie group at the foot of the wall was trying to move around the wall corpse mountain.

There are a total of seven Z-type zombies, the one at the front is one size bigger than the other Z-type zombies, and the shape is even more weird, and it is identified as Z2 by Zhang Xiaoqiang, and the remaining six Z-type zombies are no different from the ones Zhang Xiaoqiang killed before.

At the base of the wall not far from the zombies, hundreds of thousands of human beings were bleeding to death in a heap, and there were several large black pits there, the flesh and blood were blurred on the edge of the pit, and the corpses of five or six Z-type zombies were scattered on the edge of the pit.

Most of the Z-type zombies who followed Z2 were also injured, and according to the speed of Z-type zombies, they should have run far, but for some reason, they moved slowly behind Z2, and never dared to run ahead of Z2.

Zhang Xiaoqiang saw those Z-type zombies, he didn't have time to think about it, and shot out the ammunition in the barrel in turn, he didn't know how the defense of the Z2-type zombies was, so he cleaned up the Z-type zombies first, and the six bullets named the six Z-type zombies, and when he aimed at Z2, the high-frequency sound that had not been long before he suddenly sounded, and at this moment, Zhang Xiaoqiang shot out the last two bullets in the drum.

The treble is harsh, and it is also stabbing Zhang Xiaoqiang's brain, the Z2 zombie that can be seen clearly before becomes blurred in the vertigo, the bullet is flying in the air, Zhang Xiaoqiang's dynamic vision is unpredictable with the treble vibrating the brain, as if the space in front of him is equipped with a haha mirror, so that the bullet and the zombie are elongated and deformed together.

Obviously, the sound wave just now was emitted by 7 Z-type zombies together, and this time the high-frequency sound was sent out by Z-type zombies, although it was not as strong as just now, and the diffusion range was not as good as before, but the blow to Zhang Xiaoqiang was greater, and Zhang Xiaoqiang finally couldn't help howling, like a wounded wolf.

Before the howl could be shouted, the high-frequency sound turned into a piercing scream, Zhang Xiaoqiang roared out the anger in his heart, and only then did he come back to his senses and saw that the Z2 zombie had broken two tentacles, although Zhang Xiaoqiang was aiming at the head of the Z-type zombie just now, but he didn't know why he would shoot the tentacles of the Z2-type zombie.

didn't have time to think too much, Zhang Xiaoqiang grabbed the rifle next to him and jumped out of the car, and ran towards the Z2 zombie like a fly, and while running, the rifle fired again and again, and thirty bullets flew in a straight line in the air towards the Z2 zombie.

The Z-type zombie was injured, so that it paused briefly to let Mu Peipei and the little soldiers breathe a sigh of relief, when they opened their eyes and saw Zhang Xiaoqiang firing and running, they also chased after Zhang Xiaoqiang, and a hundred meters in front of Zhang Xiaoqiang, a large squid was dancing tentacles and stood among the countless fallen zombies, there is no doubt that it was the final target.

Zhang Xiaoqiang ran a distance of 100 meters in less than ten seconds, the rifle in his hand had already been thrown away, and when he sprinted, he had already held the grenade in his hand, and the bullet reached the side of the Z2 zombie, as if it suddenly disappeared, only tentacles swirled in the air.

The bullet will not disappear out of thin air, but the Z-type zombie dances its tentacles to crotch all the bullets, although I don't know how the Z-type zombie did this, but it can explain why the two large-caliber bullets just now did not work.

Zhang Xiaoqiang quickly closed the distance, but the Z2 zombie recovered much faster than Zhang Xiaoqiang imagined, when all the bullets were crotched, the high sound wave of the Z2 zombie resounded on the spot again.

Zhang Xiaoqiang was attacked by the sound wave again, his brain seemed to explode, his body had already lost his balance, and he fell and rolled in the pile of corpses, and behind him, Mu Peipei and Xiaobing also fell to the ground.

Only Wan Qiang is still hiding his entire head in the hole in the ground as he did just now, obviously, he was more affected than anyone else, there were hundreds of Type 2 zombies who guarded the Z-type zombie group before, except for more than seventy D2, the others were all S2-type zombies, only a small part of these S2-type zombies were killed by Mu Peipei, and most of them were killed by high-frequency sonic headshots from Z-type zombies.

Countless Type 2 zombies fell beside Wan Qiang, and in the broken braincase, the yellow brain pulp slowly flowed to the ground, and the semi-solidified brain pulp that was originally like bean flower became transparent in the air, gathering on the ground like glue, and slowly flowing to the big pit where Wan Qiang hid his head.

No one knows what effect these transparent brains will have on Wan Qiang when they flow into the pit, just look at Wan Qiang's whole body convulsions in the sound waves, and know that if the sound waves continue, Wan Qiang may be explained here.

There is a trench between Zhang Xiaoqiang and the Z2 zombie that can never be approached, the purpose of the Z2 zombie is to escape, and by the way, gather its men scattered in the distance to come back, while Zhang Xiaoqiang wants to approach the Z2 zombie and kill it at close range.

Because of Zhang Xiaoqiang's stubbornness, the Z2 zombie had to send out high-frequency sound waves to attack Zhang Xiaoqiang, every time it emitted sound waves, although it could make Zhang Xiaoqiang hold his head and suffer on the ground, it also made those zombies who were called back be shocked to death by sound waves.

What made Z2 depressed was that every time the sound wave stopped, Zhang Xiaoqiang showed his vitality and vitality like a cockroach, turned over and got up, rushed towards the Z-type zombie, and forcibly narrowed the distance between them from two hundred meters to one hundred meters.

Although Zhang Xiaoqiang kept getting closer to the Z2 zombie in terms of distance, he was getting hurt more and more, the closer the distance, the more powerful the sound wave roared in his head, if he hadn't exercised the willpower to never give up in the last days, I'm afraid he would have escaped a long time ago.
