The Vulcan cannon was powerful enough to penetrate all unarmored objects within a hundred meters, and the Vulcan cannon in the bearded man's hand shot the first black shadow into a sieve with a rate of fire of 6,000 rounds per minute.

The black shadow was shot by the Vulcan cannon and did not die immediately, but struggled to stand up on the ground, and only fell to the ground after the bearded man replenished a string of bullets, and the vitality was so strong that it was really rare.

As soon as the guns rang out, the battle began, and a dozen black shadows rushed towards the survivors without speed or slowness, although these black shadows all retained their human forms, their faces were distorted and deformed, and they looked terrifying in the night.

The number of black shadows far outnumbered the survivors, in the blink of an eye, six or seven survivors were surrounded by black shadows, the vitality of those black shadows was so strong that no one expected, the bullets of ordinary machine guns shot at them, although they penetrated the steel armor on their bodies and penetrated into the flesh, but they did not affect their speed at all, as if they were all iron men, and ordinary bullets were not enough to kill them at all.

The bearded man carried the Vulcan cannon and swept wildly, and the two black shadows in front of him were quickly shot into a sieve, the power of the Vulcan cannon should not be underestimated, for those black shadows, it seemed to have a deadly power, and for a while, the remaining black shadows did not dare to approach the bearded man again, and instead attacked the other survivors.

In the melee, a black shadow rushed towards Lu Fei, and Lu Fei had already noticed it, raised the pistol and immediately shot a series of bullets, the effect was already expected by Lu Fei, the bullet of the pistol shot into the body of the black shadow as if it had entered the wood, only a series of muffled sounds could be heard, the black shadow was still rushing towards Lu Fei as if nothing happened, and the bullets that entered the body did not affect his speed at all.

Just when the black shadow pounced in front of him, the bullets in Lu Fei's pistol were just exhausted, Lu Fei simply dropped the pistol and smashed it at the black shadow, only to hear the sound of bang, and the pistol smashed on the black shadow's head and made a sound like a steel impact.

The black shadow still rushed towards Lu Fei vigorously, but the next moment, an extra black sword blade appeared in Lu Fei's hand, and the black sword blade slashed down, just cutting off one of the black shadow's great heads, and it was Lu Fei who took out the domain sword in time at the moment of danger.

The head rolled to the ground, just facing Lu Fei, just a glance, Lu Fei was able to immediately conclude that these black shadows were not machines, but they were by no means humans, although they still retained their human bodies, but their faces had been completely distorted and deformed, and even their bodies had undergone some degree of mutation, much stronger than ordinary human bodies, and more lethal and destructive, especially their characteristics of being like machines that were not afraid of bullet attacks, as if their bodies were originally dead, It's just that there is an inexplicable force that governs their actions and consciousness, which is why Lu Fei did not classify them as humans.

If you use one word to describe them, Lu Fei thinks it is most appropriate to describe them as the living dead or mutants, the faces and bodies of these black shadows have been seriously mutated, they seem to have human bodies, but they are no longer human at all, and their characteristics are somewhat similar to the zombies called the living dead by humans, not afraid of bullets, no pain, no feelings, only hunger and hunting consciousness.

To be precise, these black shadows should be a new species between the living dead and mutants, the living dead refers to zombies, Lu Fei couldn't help but think of the zombies who have faced in the World War Z plane mission, zombies are not zombies, zombies and zombies are fundamentally different, zombies move faster, zombies move slowly, zombies must be transformed by the dead, afraid of light, it is said that they mainly appear in East Asia, and zombies are generally directly transformed by the living, zombies are not afraid of light, only when they see the flesh and blood of the living, will become inexplicably crazy, and the speed will also be faster because of madness.

The speed of these black shadows is not slow at all, and even faster than normal humans, so these black shadows cannot be completely described as zombies, and their faces and bodies have different degrees of mutation, it is most appropriate to describe them as mutants, after the catastrophe, there will be a pandemic, in this apocalypse disrupted by metal monsters, if human beings have evolved and mutated into a new species, Lu Fei will not question it at all, such a mutation is absolutely possible.

Lu Fei wielded the sword of the domain realm, and cut off the heads of two mutants one after another, he knew that the tenacity of the lives of these mutants was far beyond imagination, and if they wanted to kill them with one blow, they had to cut off their heads, and it happened that the space weapon of the domain realm sword was a divine weapon left over from the battle of the ancient gods and demons according to the space, although Lu Fei never felt that this broken sword was a divine weapon, and visually it seemed that there were still a few cracks on the blade of the sword, as if it would break at any time, but this broken sword seemed to be broken forever, and it was still sharpened like clay, It is extremely sharp, and to cut off the heads of these mutants is still as smooth as a quick knife cutting through the mess, and a kitchen knife cutting tofu.

But the survivors' side is miserable, while Lu Fei eliminated the three mutants, the other mutants have pounced on the survivors, the lives of these mutants are extremely tenacious, the weapons in the hands of the survivors are impossible to pose a fatal threat to the mutants, when the mutants and the survivors pounce together to start a meat game, the disparity in physical strength and strength can be seen quickly, even the most combative survivors are by no means the opponents of the mutants, these poor survivors are either broken necks by the mutants, or their hearts are taken out, One by one, the deaths were tragic, and they couldn't bear to look at it.

What's more, the number of mutants is far more than the survivors, and in the blink of an eye, except for Lu Fei, only the bearded man is left on the surviving side.

The bearded man was also saved by relying on the super firepower attack of the Vulcan Cannon in his hand, and in just a few minutes of fighting with the mutants, the Vulcan Cannon had already fired out tens of thousands of bullets.

Seeing the tragic deaths of his companions one after another, the mutants surrounded him on all sides, the bearded man had already killed his red eyes, and the Vulcan cannon fired a round of strafing, and even Lu Fei was almost pierced through his head by the Vulcan cannon's bullet with a 6000 firing rate per minute, this bearded man was really crazy.

Lu Fei secretly said that it was not good, the beard had completely lost his mind, if a person lost his mind on the battlefield, then he would not be far from death.

Mutants may still have an instinctive sense of danger estimation, and if they don't deal with the bearded man first, the mutants may have more casualties, so more and more mutants begin to risk the super fire attack of the Vulcan cannon and rush straight towards the bearded man.

The bearded man also had to turn the Vulcan cannon and shoot fiercely at the mutants who rushed in all directions.

Seeing that the bullets from the Vulcan cannon were about to shoot in this direction, Lu Fei quickly fell to the ground, and as soon as he fell to the ground, he felt a series of bullets with a wave of heat whistling over his head.
