The zombies who will only keep their heads buried in the road are too difficult to grasp on this narrow mountain road, they can only rush up along the road, because it is too crowded, some zombies are directly squeezed out of the side of the road, and then roll down the slope of the road to the end.

Because it was dark, all Fang Xing could see was the distance where the headlights of the car were turned on, but the firepower network composed of three heavy machine guns showed its might in such a narrow shooting range, and none of the zombies crowded on the road could rush up.

Although this place is a desperate place, it is also very easy to defend, as long as a few machine guns swing here, you can't get out, and the zombies can't get in, if you want to get out, you have to deal with the zombies at the door first.

It's no joke to fight with so many zombies, if it weren't for these machine guns, zombies would have trampled people into meatloaf even if they stepped on them.

Fang Xing took a flashlight, climbed up along the cliff on the side of the road, and then quickly walked towards the zombie Fang Xing on the road, he was holding a somewhat worn backpack in the middle of the week, there were dozens of grenades in the backpack, and the zombies below had fallen a pile, but the zombies behind were lined up in a long line and were squeezing forward without fear of death.

One grenade was thrown down, killing a large area, and then a dozen of them were swept down the side of the road and rolled down the hill by the shock wave.

With such a density of zombies, whether it is with a machine gun or a grenade, it can exert the maximum power and achieve the best casualty effect.

Fang Xing threw the grenades down one by one, the explosions in the zombie group were one after another, the scene was unbearable, and the zombies still had no fear, the sound of the machine gun roared continuously stimulated them, and they continued to squeeze forward.

Fifty miles away from the muzzle of the machine guns, the corpses of the zombies were piled up at about the height of people, forming a zombie wall, and the zombies behind rushed up, and many of them would trip over the corpses of these zombies and then be hit by bullets.

In the blink of an eye, Fang Xing, who originally occupied an absolute disadvantage, took advantage of the terrain here to slowly gain the upper hand, but fortunately, today they were ready to clean up the zombies, and they carried more bullets, so there should be no problem in killing these zombies.

At this time, a huge roar sounded in the valley, and this roar was like thunder, even drowning out the sound of machine guns.

After hearing this voice, I saw that the zombies who were attacking stood one after another, and then turned their heads and ran back, and the zombies actually ran away, which was really the first time I had seen it.

At this time, the mountain road has been blocked by the corpses of zombies, and even armored vehicles will definitely not be able to drive through.

There was an echo in the valley, and everyone just now only cared about killing zombies and didn't pay attention to it, so it was unknown from which direction the zombies' retreating roar came from, and Fang Xing only knew that the one who could lead the zombies was definitely not a vegetarian character.

The third-level zombies have a certain leadership ability, they can lead a large group of zombies to follow their direction, and the leadership ability of the fourth-level zombies is stronger, which is equivalent to the second leader in the bandit group, and now a roar can command the retreat of the red-eyed zombies, which is not what these third- and fourth-level zombies can do.

That is to say, there is a character behind these zombies who is much more powerful than the third and fourth level zombies.

In less than half a minute, all the zombies had withdrawn from the machine gun shooting, and Zhao Yiyi and the others stopped shooting, panting for breath for the rest of their lives.

The barrel of the machine gun on the car is already red, and if it continues to fight, it will have to be scrapped, and now the zombies are retreating, although I don't know what the reason is, but they can finally take a breath.

"Fang Xing, I've never seen a zombie run away, what's going on? Have they evolved? Lin Xin asked very suspiciously.

Fang Xing looked at the dark direction where the zombies disappeared, and said leisurely: "They are indeed evolving, but they have evolved like wolves, they are group animals, they have leaders, and the roar just now should be the head of the zombies sending a signal to retreat." ”

This is an explanation, although ordinary zombies are much stronger than ordinary people in all aspects of physical speed, they have no advantage over normal humans in the face of 'automatic weapons'.

But as long as you gather them all together, it will be much more difficult to deal with than high-level zombies.

Looking at the swarthy mountain col and the zombies full of dead and wounded, Fang Xing Zou frowned, and a very bad premonition rose from his heart.

Fang Xing asked people to replace the barrel of the vehicle-mounted machine gun, and then prepared the bullets to prepare to continue the battle, the vision in the dark was limited, and whether there were zombies approaching could only rely on the idea of Zhou Bo, the zombie early warning aircraft, to search.

It was so quiet in the darkness that it was a very dangerous signal, Zhou Bo closed his eyes violently, and hurriedly shouted: "Be careful, the zombies are here again!" ”

As soon as his words fell, a zombie rushed out of the darkness and appeared in the field of vision of several people under the headlights, this is a third-level zombie, his speed is very fast, and his eyesight is not affected at all by walking against the light.

Zhao Yi had just changed the barrel of the heavy machine gun and fired, and the bullet punched a few holes in the body of the third-level zombie.

The zombies fell in response and lost their ability to move!

This machine gun is equipped with armor-piercing bullets, which can be effective even if it is used against level 4 zombies.

There is a third-level zombie appearance, which is a bad signal, Zhou Bo continued to close his eyes, very carefully searching for the zombies around him who might have been touched in the dark.

Cold sweat only broke out on both sides of his forehead, and when he opened his eyes again, he only shouted two words: "Be careful, run!" ”

Run? Where to run? This narrow mountain road is blocked at both ends, and if you don't clean up the zombie corpses piled up in the mountains, let alone cars, even people can't climb out, after all, not everyone has the ability to wake up.

I saw that in the darkness, more than a dozen third-level zombies and fourth-level zombies rushed up, their speed was fast, and several fourth-level zombies quickly crawled along the rock wall on the side of the road, and arrived next to Fang Xing in the blink of an eye.

The three heavy machine guns fired together, and Fang Xing pulled out the eight-sided Han sword and killed the zombies next to him first.

The sharpness of the eight-sided Han sword is okay, the head of a fourth-level zombie was directly cut off by a sword, and the head of the other was directly pierced, and the sword body was twisted vigorously, leaving a deep hole in his head.

The zombie fell straight to the ground and twitched, and Fang Xing also cut off his head very decisively.

Under the frantic fire of the machine gun, there were several corpses of third- and fourth-level zombies on the ground, and those who were not killed quickly retreated and disappeared into the darkness.

Everyone's vigilance did not dare to relax at all, and these zombies now were a little different from what everyone had known in the past, they were as cunning as wolves.

In this night, if Zhou Bo is not here, he will have to suffer a big loss just by relying on a few naked eyes! PS: Thank you very much for your support!
