The sound came out, and the still world in front of him began to move slowly, a faint flame burst out at the muzzle, a few wisps of green smoke slowly floated up, a conical bullet rushed out of the chamber, the air near the muzzle began to stir, and as the bullet rushed forward, the transparent agitation wave became larger and larger.

The surrounding scene changed faster and faster, and the speed of the bullet forward became faster and faster, and between the lightning and sparks, the bullet had broken through the speed of sound, out of reach of the naked eye, and a puddle of blood immediately burst out from a hideous and terrifying head in front of it, splashing in all directions.

A large wound appeared in the center of the skull, followed by a stream of blood in the back of the head, and the bullet pierced the entire skull, and then slammed limply into the wall, falling to the ground and rolling incessantly, making a jingling sound.

"Roar—"

The D2 zombie let out a painful roar, and it was only at this time that the world in front of Zhou Xiaoyu returned to normal, the extremely slow and rapid transformation made him feel nauseous, his mind was extremely dizzy, he closed his eyes and shook his head vigorously, and opened his eyes violently, only to find that the D2 zombie was rushing towards him with that terrible wound.

"Oops—"

Zhou Xiaoyu's face changed suddenly, and after such a shot, the D2 zombie still had the strength to hurt people, and the crouching body did not stand up, and quickly rolled to the side, wanting to avoid this blow, and then escape.

But he began to inadvertently enter that magical state, so that he lost a lot of physical strength, and his usual vigorous skills disappeared completely, and for a while, he did not adapt to it, and a roll did not come and finished, and with a pop, there was a heavy sense of pressure in his feet, and the tumbling action was interrupted.

Zhou Xiaoyu hurriedly looked back and saw the D2 zombie fall to the ground, his whole body pressed horizontally on his feet, his arms raised, and he grabbed his thighs, and secretly screamed in his heart that it was not good, this is really the end.

Despite this, he still didn't give up in his heart, it was too late to draw his legs, the sniper rifle in his hand swept desperately, and swung it at the raised arm of the D2 zombie, but unexpectedly it was empty, and his hand was fluttering without any strength.

What's going on?

At a glance, it was the arm of the D2 zombie that had become weak, and the speed had become very slow, and his full force was hit according to the speed at which it started, but this time it passed under its arm, and it didn't touch the D2 zombie at all.

The D2 zombie's arm had just fallen, and the head had been lost, and the sharp nails clawed at the thick watery ground, and the debris flew up, falling into a few small shallow pits, and then the arm was no longer able to lift up.

The D2 zombie bared its teeth and let out a low roar in its mouth, wanting to continue attacking Zhou Xiaoyu, but its whole body seemed to be uncontrollable as if it had broken a string, and it began to twitch uncontrollably.

"Good!"

Zhou Xiaoyu understood that his attack was effective, and this shot directly hit the vital point of the D2 zombie, it was only dying at this time, and its life was hanging by a thread, and it was powerless to hurt itself at all.

The noisy corpses in the corridor are approaching, and it will not take a minute to enter the rooftop, his heart is pounding at this time, and his whole body has been in a cold sweat, and he thinks fearfully: "It's really a fluke, but I must solve the D2 zombies as soon as possible, otherwise as soon as the corpses come up, I will be in danger." ”

Avoiding the D2 zombie's minions, he carefully pulled his legs out from under it, struggling to get up, but stumbled and almost fell to the ground.

Trying to stand up straight, the sniper rifle was aimed at the dying D2 zombie to make up for a shot, but when he pulled the trigger, it stopped suddenly, and it is still unknown whether he can get energy after killing with a gun, so for the sake of safety, it is better to use a knife.

At this time, the D2 zombie was on the verge of dying, Zhou Xiaoyu quickly threw away the sniper rifle and pulled the knife off his back, and a staggering zombie had already appeared at the entrance of the building, and there were countless minions waving behind him.

"Quick—"

Ignoring the movement, Zhou Xiaoyu shouted, his hand rose and fell, the cold light was like the glow of the cold moon, refreshing people's souls, and directly cut into the neck of the D2 zombie.

Different from cutting ordinary zombies, as soon as the blade entered the **, Zhou Xiaoyu felt a jerky feeling, full of resistance, and was secretly surprised in his heart, the physical strength of D2 zombies is really strong, far from being comparable to ordinary zombies, even F1 zombies are far worse than it, and it is not a level at all.

Holding the knife from one hand to two hands, holding his breath and making a muffled cry, the strength of the whole body is all concentrated in both hands, the knife is ruthless again, the knife is penetrating, a sore tooth sound sounded, the blade went deep into the neck and went down, and then clanged, slashed on the ground, splashed a few sparks, and the knife finally did not bear the load, broken into two.

A stream of dirty blood spurted out of the neck of the D2 zombie a few meters away, and the head also rolled down with a gurgling, but the eyes were still wide open, and the jaw was still biting.

"Uh......h Roar ......"

Several zombie roars sounded around him, Zhou Xiaoyu jumped forward, threw the broken knife in his hand back, and the whistling sounded, and the short knife pierced the heads of several zombies one after another like sharp arrows, connecting them together.

His body rolled, his hand touched the ground, picked up the Type 03 automatic rifle, and began to strafe before he could get up.

"Da Da Da ......"

Fierce gunfire rang out, angry sparks erupted from the muzzles, and the heads of several zombies were riddled with bullet holes before they fell.

The zombies at the entrance of the corridor kept pouring out, and Zhou Xiaoyu solved the few zombies next to him, and then aimed the muzzle of the gun at the entrance of the building.

"TMD Die!"

At the same time, he held down the trigger tightly, the bullet casings fell cracklingly, and the sound of gunshots, Zhou Xiaoyu's shouts, and zombies' roars rang out in the narrow space of the rooftop.

The zombies kept falling, and then a new zombie appeared at the entrance of the building, and the D2 zombie was not completely dead, the head rolling on the side was still moving at this time, and the energy had not been absorbed, how could Zhou Xiaoyu leave just now.

At the same time, he jumped to the side of the D2 zombie's head, raised his right foot, and with all his strength, Martin's boots stomped down, trying to break the D2 zombie's head in one fell swoop.

Unexpectedly, his feet were numb, and he stepped on an iron stone before, and the head of the D2 zombie was not half damaged, and under the force, he just rolled away like a ball.

"Holy! TMD is really tough! ”

Afraid that he would not be able to get the evolutionary energy, Zhou Xiaoyu did not dare to kill it with a gun, so he could only let it slowly lose its breath, and the cold weapon had been lost, so he could only rely on the automatic rifle in his hand to resist the endless crowd of corpses.

"Click! Click! ”

The D2 zombie is not dead, and the rifle in his hand has already knocked out the bullets, Zhou Xiaoyu quickly replaced another rifle with a full magazine, and continued to splash bullets at the entrance of the building.

The zombies at the entrance of the building have piled up very high, but they are always pushed away by the zombies inside, and the rooftop is already full of dirty blood, flowing outside along the ravines on the ground, and the smell is overwhelming.

When he changed into the third rifle, Zhou Xiaoyu trembled, the pores of his whole body were completely opened, and a familiar coolness finally reached him.

The D2 zombie is finally dead completely.
