In the stairwell, a manic and tyrannical roar rang out continuously, followed by a rush of panicked cries for help.

It can be seen that two different figures, one high and one low, are chasing quickly along each ladder, climbing from bottom to top, the speed is very fast, but the pursuers are obviously more skilled, and the distance between the two sides is constantly narrowing.

Running on the upper stairs as a fugitive was a slender woman with short hair wearing a blue and white long-sleeved sportswear, about twenty-five years old, although her expression was slightly flustered, but the action of climbing the ladder was swift, fast and powerful, and she couldn't see the skills that an ordinary woman could have.

The pursuer at the bottom of the stairs is a giant Alaskan dog with a murderous aura that is full of black energy.

When ordinary people see such a picture, they are surprised, and it is absolutely difficult to imagine that the two were still intimate and pet-loving ten minutes ago.

As a victim of the current scene, in addition to the instinctive panic and fear that An Lan instinctively generated after his life was mortally threatened, there was still a lingering look of surprise and incomprehension in the depths of his eyes.

She didn't know what was wrong with the world, and overnight, everything she was familiar with had changed dramatically, everything was instantly stained red with blood, and there was only endless mourning in her eyes.

It is like the beginning of the end of the world, and everything is headed for destruction.

She was completely unprepared for this.

Just like now, An Lan would never have thought that she would only retire from the special operations force two years ago, and now she will be chased and killed by a dog so much that she can only choose to run away, and it is also a dog raised by herself.

One moment Xiaoya (the name of the mutated Alaska who chased her in the back) was docile and well-behaved like her own child, and the next moment it had red eyes, like an angry lioness who had been robbed of her cubs, and suddenly turned around and pounced on herself.

If it weren't for her rich combat experience, she turned over on her side in time to avoid Xiaoya's fast and ruthless pounce——, at that moment, she was embarrassed and her face was full of shock, and she did feel an extremely strong cold killing machine that wanted to kill her from Xiaoya's red eyes!

Why is this happening?

Are you crazy?!

An Lan couldn't have imagined that the pet dog that had been with him for almost two years would suddenly rebel today and become a mad dog who was desperate to chase and kill him.

What she couldn't figure out was that after retiring from the army, she became a wealthy private female bodyguard and defeated many outlaws, but at this moment, she couldn't beat a pet dog she raised.

At this time, the red-eyed little girl who was chasing after her was not at all clumsy and stupid as usual, and she was as fierce and terrible as a cheetah, even if she found an opportunity to kick it out and roll directly down to the bottom of the stairs, she was unscathed, but pounced more fiercely.

The murderous blood pupils, the violent posture of wanting to choose people and devour, ordinary people will feel cold in their hearts and the soles of their feet will be soft when they see it.

An Lan could feel the terrifying aura that was approaching behind her, and under the pressure, her face turned slightly pale, and she ran to the upper floor of the stairs with all her strength, and shouted loudly along the way, hoping that the other residents could come over to help her after hearing it, and block the mad dog behind her!

Someone did hear her cries for help, but at the same time, they heard Xiaoya's terrifying and huge roar.

After last night's blood-scarring virus riot, the surviving occupants of this building chose to close their doors firmly to avoid being broken into their homes by the crazy horror creature.

An Lan was about to despair, she knew that the iron door leading to the rooftop on the top floor had been locked, and it would be a dead end to continue to go up.

The only way to survive is to go back to her own house, but the little girl behind her chases too closely, even if she can run to the door of the house, there is no time to take out the key to open the door, let alone keep the fierce little girl out of the house.

The hope of returning home was slim, but she had no other choice.

Rushing up to the twelfth floor in one go, An Lan quickly grabbed the half-human-high white trash can placed at the staircase, and at the same time, the violent little girl behind her had already rushed up, with a strong fishy wind.

"Yikes!!"

An Lanjiao scolded, raised the white bucket full of garbage with both hands and threw it at the little girl who pounced on her with all her might, and she immediately turned around and ran.

She heard the roar of the little girl who had been hit by the trash can after falling down the stairs, and soon approached again, like a life talisman.

"It's got to be in time!"

An Lan rushed out of the staircase and rushed towards the direction of her own house at full speed, but then she noticed that there was already someone standing in front of her, a male neighbor she was not familiar with.

At this moment, the other party was wearing a whole set of tight-fitting black clothes with a strange style, and he was actually holding a decent dark blue sharp knife in his hand, just standing in the middle of the road, looking at her with a calm face.

What does he want to do? Heroes save beauty?

No kidding!

Even she can't beat the little girl behind, how can this ordinary young man be an opponent right now?!

"Go home and hide!!"

An Lan ran as he anxiously waved and shouted to the black-clothed knife-wielding young man standing in front.

To her surprise, the young man in black didn't pay attention to her at all, and even looked directly past her, looking at the violent little girl who had rushed out of the staircase behind her.

At this time, An Lan would not stop, the moment she rushed past the young man in black, she looked at the other party's face with the corner of her eye, without capturing a trace of nervousness or fear, the other party's eyes were calm and focused from beginning to end, and her whole body exuded a rock-like calm momentum.

Whether it is pretending to be or not, an ordinary person can still behave like this in the face of a giant Alaskan dog that has fallen into a rage, to be honest, she was really a little surprised and admired at that moment.

But An Lan, who knew the horror of Xiaoya, didn't think that this young man would be able to stop Xiaoya, who had completely fallen into a state of rage, even if he had a knife in his hand that looked good.

Because even if she was holding the knife, she didn't have the slightest confidence that she would be able to defeat such a terrifying little girl.

An Lan didn't believe that this male neighbor, who usually had little to come from, would have a stronger melee fighting ability than herself.

So at the moment when she rushed past the man, she had already sentenced the other party to death.

She won't turn back, otherwise there may be two people who died under Xiaoya's sharp fangs.

Since the other party wants to be strong, then she will not be reluctant, in fact, it is precisely because of this male neighbor in front of her that she has a chance to breathe and survive.

Although he didn't want to admit it, at this moment, deep in An Lan's heart, he hoped that the other party could hold on for a while longer, so that he could escape from the current danger of life and death.

As long as you get back home, then having a heavy alloy security door as a barrier is enough to keep the completely crazy little girl out.

After that, she only needs to contact a few officers she knows here through the secret signal channel to explain the situation here, then she will gather the forces of the government at that time, and she is not afraid that she will not be able to subdue Xiaoya.

couldn't breathe, An Lan had already thought of the next plan of action.

She rushed to the door of her house and quickly removed the key from her trouser pocket, while subconsciously looking back at the male neighbor.

She thought that she would see the bloody picture of the other party's tragic death in the mouth of the little girl, but then, she saw a scene that she would never forget for a long, long time in the future.

That scene was a little different from what An Lan had expected, she guessed the beginning, but she didn't think of the end.

The little girl who was chasing after was really attracted by the black-clothed young man with a knife standing in the middle of the roadway, roared at high speed, and pounced decisively.

As a giant Alaskan family, it is no less than an adult Tibetan mastiff in size, and it is even stronger after mutation, and its weight is definitely more than 100 kilograms.

Such a ferocious dog pounced on it, and its appearance alone was enough to scare the courage of ordinary people, let alone fight it.

The mutated little girl's pounce speed is even faster than that of an adult cheetah, and ordinary people can't react at all.

However, the young man in black with a knife made an unexpected reaction speed!

At the moment when the giant little girl was about to pounce in front of the knife-wielding young man, she saw a dazzling green light flash like lightning, and even An Lan herself didn't see the movements of the black-clothed young man clearly, and the giant little girl who was attacking head-on had already been slashed in the head by the black-clothed young man with a knife!

It's so fast!

What's even more terrifying is that the little girl, who already has the weight of an adult man, was directly chopped out by the young man in black with a knife, let out a terrible and heavy howl in mid-air, fell a few meters away, and a huge hideous wound opened at the position of the skull, and after falling to the ground, the whole body spasmed, a large amount of blood gushed out, quickly stained the ground red, and it seemed that he could not live.

The violent little girl who was difficult to match in An Lan's eyes was actually killed with a knife like this!

"This ......"

Time seems to stand still. An Lan looked at this scene dumbfounded, her breathing suddenly became suppressed, and the bunch of keys that she was originally holding in her hand quietly fell to the ground-
