Under the pursuit of twelve mutant soldiers, originally, with unparalleled speed and strength, it was actually a very simple thing to get rid of the enemy's siege.

However, when she retreated, she also had to shoulder the responsibility of protecting Yang Zheng's safety, which invisibly added huge pressure to her.

Yang Zheng's body has also improved significantly after being modified by the mutant gene, but compared with the tough mutant soldiers behind him, the gap is still too big.

Two waves of people and horses, while constantly retreating, are frantically chasing, but Yang Zheng, who is hanging behind Wushuang, to a large extent, is the one who pulls Wushuang's hind legs, so that Wushuang has to slow down often to take care of him.

Under the advantages of the other, the speed of Wushuang and Yang Zheng's evasion is getting slower and slower, while the mutant soldiers chasing behind them are getting faster and faster, and the distance between the two sides is constantly shortening and narrowing, from the distance of one hundred and ten meters at the beginning, to less than twenty meters now.

With such a short distance, Wushuang no longer dared to turn around and snipe at the enemy.

Because, as long as she shoots, she can only kill one or two enemies at most, but when she shoots, five or six tough mutant soldiers will besiege her on the left, center, and right at the same time.

Although Wushuang has not yet fought with these mutant soldiers in close combat, with her eyesight and intuition, these mutant soldiers wearing the Black Four-Wing Medal are absolutely super strong in hand-to-hand combat.

And judging from the sound of their running footsteps and speed, the comprehensive strength of these guys must be above the perfectly evolved blue-blooded people.

Although Wushuang's personal ability is also very strong, after all, she is best at long-range sniping, and if it is a close combat, she can deal with the siege of up to three mutant soldiers at the same time, and there is no hope of victory at all.

Seeing that the enemy was getting closer and closer, if Wushuang and Yang Zheng continued to escape, they would soon be surrounded by the pursuing enemy.

At that time, it will be difficult for her and Yang Zheng to get out.

At this moment, the nearest mutant soldier to them was already less than ten meters away.

I saw this mutant soldier, his blood-red eyes, the fierce light was magnificent, and he stretched out his feet and kicked on the ground, and suddenly, his black body, like an arrow from the Xuan, shot towards Wushuang quickly. At the same time, on the left and right, several more enemies rushed at a sharp acceleration.

All of a sudden, Wushuang and Yang Zheng were attacked on three sides, and at this moment, in addition to turning around and counterattacking, continuing to escape was undoubtedly sending them to death.

Seeing this scene, Wushuang immediately made a decision, turned his delicate body like a whirlwind, and shouted: "Yang Zheng is on the right side!" I'll take care of the rest......"

Hearing this, Yang Zheng instantly understood her intentions, and at that moment he picked up the shotgun that had been loaded with special ammunition a long time ago, and pulled the trigger fiercely at the mutant soldier who was rushing on the right.

At a distance of less than ten meters, an ultra-short shot like this will undoubtedly give full play to the power of a shotgun.

"Bang!"

I only heard a dull loud noise, Yang Zheng, who was holding the gun in both hands, was shocked by the recoil generated when the shotgun was fired, and suddenly, I saw the silver-white muzzle flames, and the mutant soldier who had rushed to three meters away was blown to a blur of flesh and blood on the spot, and the entire upper body was torn apart.

After a terrible scream, the corpse of the mutant soldier, which had been shattered by the shotgun, slammed into the ground, and the blood mist and shattered internal organs of the explosion flew in all directions.

Seeing a companion die tragically under the intruder's terrifying shotgun, the remaining mutant soldiers changed color in unison, although they were not afraid of death, but they never expected that the silver-white shotgun in Yang Zheng's hand actually had such terrible lethality.

You know, they have gone through a lot of experiments before, like ordinary rifles and shotguns, it is simply impossible to inflict fatal damage on them, and as for killing them on the spot, it is even more impossible.

The only explanation is that the ammunition of the silver-white shotgun in Yang Zheng's hand must be strange, as if he was born to be their star and has a powerful destructive power for the mutant genes in their bodies. Once hit, they can be killed on the spot, or their genetic damage will degenerate, and their wounds will not heal at all.

Knowing this result, the remaining mutant soldiers, they became even more crazy.

I saw that their eyes were flashing with intense bloodthirsty killing, as if they were about to tear Yang Zheng and Wushuang in front of them to pieces.

Just now, Yang Zheng used special ammunition to kill a mutant soldier, Wushuang also used her strong marksmanship and skills to kill two enemies again, and when she quickly pointed the gun at the third mutant soldier, it was too late.

Because, these mutant soldiers, although they have no weapons, they do not flinch, and they are obviously doing a good job of fighting for their lives.

At the cost of losing four of their companions, they managed to get within three meters.

Soon, Musou put away his sniper rifle and fought with the two mutant soldiers who rushed first.

Both sides have super strength and speed, and Wushuang and the two enemies punched back and forth, punching to the flesh, and the fierce collision caused by the violent fight made Yang Zheng tremble in horror.

In order to alleviate Wushuang's pressure, Yang Zheng quickly rushed behind Wushuang after killing an approaching enemy, picked up his shotgun, and prepared to blast the two murderous enemies in front of him away.

However, at the moment when he was just about to pull the trigger, a mutant soldier a few meters away on the left jumped up in the air and rushed straight towards Yang Zheng like lightning, so fast that it didn't give Yang Zheng any chance to dodge and fight back.

In the face of this drastic change, Yang Zheng had to temporarily change the direction of the muzzle of the gun, preparing to blast away the enemy who was killing him. It's a pity that before he could shoot, he was kicked in the chest by the enemy who came from the volley.

With a muffled sound of "bang", Yang Zheng was kicked several meters away on the spot, and at the same time as being kicked away, he clearly heard a clear sound of bones breaking on the left side of his chest.

For a while, he screamed "wow" and spurted out a mouthful of blood, while he struggled to pick up the shotgun that fell not far away, but as soon as his body moved, he felt a burst of heart-piercing intensity in his chest, and he inhaled cold air in pain.

After the mutant soldier kicked Yang Zheng away just now, he chased after him with a fierce look, only to see him rush to Yang Zheng, quickly raise his left foot and aim at Yang Zheng's head, looking like he was about to seriously injured Yang Zheng, and stepped on it into meat sauce.

Seeing this scene, Yang Zheng's frightened soul flew for nine days.

At this time, the situation was very critical, and Wushuang tried his best to force back the siege of the three enemies, and rushed towards Yang Zheng's side without his life. However, several enemies on both sides of her body came to besiege her with no death, and she stumbled and could not protect herself. Under the pursuit and siege of five mutant soldiers, no matter how strong Wushuang is, it is difficult to get out.

Seeing that Yang Zheng was about to die at the feet of the mutant soldier, her anxious pupils were bloodshot and her eyes were about to split.

However, at this critical moment, Yang Zheng only heard a thunderous footsteps, which were rushing towards him very quickly.

Knock knock knock......

The sound of running footsteps was so heavy that the earth shook!

Just as the mutant soldier's raised left foot was about to step on Yang Zheng's head, suddenly, a three-meter-tall steel giant suddenly appeared, only to see it swing its bucket-thick steel arm and punch the mutant soldier's back fiercely.

With a loud "bang", the mutant soldier who wanted to trample on Yang Zheng was blasted out more than ten meters away by the steel giant on the spot.

A terrible scream came from afar, and I saw the mutant soldier who was hit hard by the iron giant's fist, his back was deeply dented, and a large amount of blood clots and broken internal organs gushed out of the mutant soldier's mouth. The corpse fell to the ground, and his eyes gradually dimmed, looking at the behemoth more than three meters tall, there was a rare horror in his eyes.

The steel giant that suddenly appeared, after relieving Yang Zheng's crisis, quickly took a big step and headed towards Wushuang like lightning.

Looking at the incomparably heavy steel giant, Yang Zheng was stunned, "See...... Hell, what the hell is this? Mecha? ……”

At this time, Wushuang was under the siege of six or seven mutant soldiers, and she was already covered in wounds, and blood kept flowing from her mouth, obviously, she had suffered a heavy blow.

"Wushuang, lie down!"

Suddenly, something surprising to Yang Zheng appeared, and the rough voice of a rhinoceros actually came from within the iron giant. In an instant, Yang Zheng understood, it turned out that this steel giant, which looked more than three meters tall, was originally controlled by a rhinoceros.

Seeing that the rhinoceros finally came to support, Wushuang couldn't help but breathe a deep sigh of relief, and fell to the ground on the spot, making room for the steel giant behind him to make a move.

"Death, you disgusting wretchants!"

With a thunderous roar, the rhinoceros immediately controlled the steel giant, waving its hard and thick steel giant arm, and swept like thunder.

Suddenly, the screams rang out in an endless stream, and the three mutant soldiers who couldn't retreat were swept away a few meters away on the spot, and when they landed, their upper bodies were smashed by the steel heavy arm, and they couldn't survive.

The remaining mutant soldiers, seeing that a fierce steel giant had appeared in the opposing camp, gave up the senseless attack and quickly retreated.

However, before they could retreat ten meters, suddenly, behind Yang Zheng and the others, the sound of a series of rockets was fired.

Shout! Shout! Shout! ……

I saw four red rockets with the thickness of an arm, like four meteors shooting at each other, dragging their long flame tails, whistling towards several retreating mutant soldiers.

When the mutant soldiers saw the rockets fired, their faces changed dramatically on the spot, and they were looking for cover to dodge, but no matter how fast they were, how could they be as fast as the rockets?

In that short moment, four rockets bombarded the mutant soldiers.

Rumble! Rumble! Rumble! ……

Four explosions in a row shook Yang Zheng and the others deaf.

And the mutant soldiers who were hit by the rockets were torn apart on the spot, turning into clouds of flesh and blood mist, flying all over the sky.

Seeing this scene, Yang Zheng was shocked, and tried his best to look up behind him, only to see a thin and tall viper a hundred meters away, with a rocket launch system with four launch pipes on his shoulder, walking towards them expressionlessly.

"Wushuang, are you all okay?" Although the viper's tone was cold, there was a rare concern hidden in his eyes.

Wushuang struggled to come to Yang Zheng's side, tried his best to help Yang Zheng up, and said breathlessly: "Why did you only come now, didn't I inform you a long time ago?" ”

Hearing this, the viper frowned and said, "When the airport opened the lift gate, it was discovered, and the rhinoceros and I also killed all the way in." ”

Wushuang's pretty face changed, "What do you mean, we're all trapped in here now?" ”

The viper didn't speak, but nodded.

Wushuang took a deep breath, pondered for a moment, and said, "I still have thirteen bullets, how much ammunition do you still have?" ”

"The Rhino has long run out of ammunition, and I only have four AR rockets left here."

"Ahem...... Yang Zheng coughed violently a few times and said, "I still have more than a dozen special ammunition here, I don't know if it's enough......

Before Yang Zheng's words were finished, everyone heard a burst of stampede of footsteps at the end of the entire underground base.

Suddenly, the rhinoceros sitting in the steel giant, he took advantage of his height, carefully observed the surroundings of the base, and said in a solemn tone: "It's not good, a thousand meters away in front of us, there was a phalanx composed of three hundred mutant soldiers, all equipped with full firepower and equipment, and behind us, there was also a heterogeneous team, with more than five hundred people, all of them were fully armed, it seems that they are really serious this time." ”

As soon as these words came out, everyone changed color, and their mood became extremely heavy.

There was silence for a moment, and suddenly, the viper, who had not spoken, flashed a trace of imperceptible helplessness and sadness in his eyes, sighed softly, and said, "It seems that this is the last time we will fight side by side......"
