That strange scream couldn't stop Zhang Lang.

When the ruby-like object was swallowed into his mouth, his body trembled violently.

In an instant, it seemed that he had lost all his strength, and the whole person fell to the ground.

It was at this moment that a figure in a white coat ran out of the happy door of the warehouse.

As if crazy, he ran towards Zhang Lang who fell to the ground.

This is an old man, about sixty years old, with a red face. Don't look at his gray and sparse hair, just look at the face without wrinkles, more like a middle-aged man.

At the moment when the old man appeared, Nalan Qingrou, who was lying on the ground, suddenly opened her eyes wide and exclaimed in disbelief.

"Teacher? Why are you here? ”

……

2001!

During the year, there were a number of cases of missing children around the world.

In the same year, a killer organization trained thousands of children between the ages of five and ten.

A group of young children are placed under house arrest on a desert island for hellish training to hone all kinds of combat knowledge and assassination techniques.

In this military base, all the children learned two words, obedience!

Obey the command, obey the training, obey the instructor......

These children live in hell.

From the day they were brought to the base of this unknown island, their mission was to learn, non-stop, to learn culture, to learn anatomy, to learn computers, to shoot and to fight, to learn to drive all kinds of vehicles, military tools......

But everything that can be mastered by human beings must be learned, and it must be learned!

As long as there is a slight slackness, a slight failure in that item, and a slight mistake, it will inevitably lead to a brutal beating.

The instructors who train them will focus on the weakest and most painful areas of the body, and they will not hurt the body.

It can ensure that after the children are severely beaten, they will not be in any physical danger, so that the punished children can exercise normally and continue to eat, sleep, and study......

That kind of pain is unimaginable to any person.

They are afraid, they hesitate, but in order to survive, they can mercilessly kill their fellow soldiers.

A thousand people gradually became a hundred, and a hundred people slowly became ten.

Until......

Nine of the ten children died in the fight, leaving only one girl.

She became a ...... with no feelings, no weaknesses, no humanity

Killing machine!

2010.

The United Nations counter-terrorism unit arrives on a peninsula in the Martinique Islands to encircle and suppress a training base for killers.

After three days, with thousands of casualties, the organization was finally breached and more than 600 members of the organization were wiped out.

A cell on the lowest level of the base was opened, and the special operations forces found a girl of about fourteen or fifteen years old.

Outcome......

The remaining 463 members of the multinational anti-terrorist special combat team were all killed!

And the girl's whereabouts have not been known ever since......

……

"Why save me?"

A thin girl covered in wounds, looking at the old man in front of her, her eyes were so indifferent, without a trace of human emotion, like a ferocious young beast that had just grown fangs.

"There is no why. If anything, it's just some curiosity, some pity...... The main thing, I need an assistant," the old man said with a chuckle.

“……”

A girl with abilities beyond ordinary people was silent.

The old man saw that the girl did not speak, and the smile on his face became even stronger, "Of course, I didn't save you in vain." Remember, and always remember, that I have given you your life to come. ”

"What do you need me to do?" The girl raised her head, staring at the old man with a blank gaze.

"I haven't thought of it yet." The old man shook his head, only to ask a strange question, "Do you believe in fate?" ”

"Don't believe it!" The girl thought for a moment and shook her head, "I only believe in weapons. ”

"But I believe that fate is a very strange thing, and maybe one day, you will see it." The old man laughed, "When you appeared, I found that maybe my experiment could be successful soon." ”

From this day on, the girl followed the old man and became the old man's assistant.

The old man didn't treat the girl very well, but for a girl who never knew what warmth was, the old man gave her everything now was so beautiful.

Gradually, the girl grew up.

It was as if she had forgotten that she had been a killing machine, and like any other normal girl, she began to learn to live.

Until one day, she had just graduated from college and was taken to a laboratory by the old man.

In the laboratory, the old man took out a piece of green jelly-like object and handed it to her.

"Now, you can give me your life."

"What is this?" The girl looked at the green object and asked the old man.

"It's called corpse crystal, and it's an essence extracted from human beings after their mutations."

The old man patiently explained, "The corpse crystal has an incredible ability. As long as human beings touch it, they can access the full potential of another human being......"

Through the old man's narration, the girl was shocked to find that this green thing turned out to be a crystal that someone deliberately condensed all the 'essence' in a human body through some means.

She didn't understand why it was called a 'corpse crystal'.

But she knew from the old man's mouth that it was very dangerous to touch the corpse crystal.

It must also be devoured like eating food to achieve the most perfect state of touching the corpse crystal.

Is it dangerous?

The girl sneered.

For her, being in a dangerous thing is not as good as being trained to be a killer when she was a child, and it is not as good as surviving after fighting hundreds of killers of the same age.

Since the old man said that he would take back the life he had given her, although she was a little reluctant, the girl still picked up the corpse crystal and ate it in her mouth......

Fortunately, after eating the corpse crystal, the girl was only in a coma for about ten days and did not die.

After waking up, the girl became an old man's test subject and began to conduct various experiments......

Another two years have passed.

In the past two years, she has been exposed to too many incredible, experimental subjects like her.

These experiments include humans, animals, and some creatures, zombies, mutated zombies......

The world has suddenly exploded into a zombie crisis.

This day was the last time she and the old man saw each other.

The old man said to her, "You are free." You are your destiny, and now you are yourself. As for whether you can survive in the future, and how long you can live, it's up to you! ”

The old man left and was picked up by a helicopter.

After the old man left, a group of people with guns and ammunition rushed into the old man's laboratory, trying to arrest the old man and want to arrest her.

Those with weapons were so ridiculous and vulnerable in her eyes.

As a last resort, she restarted the killer instinct that she had forgotten for more than ten years.

Those people are dead.

She left the lab, the city that was familiar and strange.

A man came to a distant place, to another city full of zombies.

met a young man named Zhang Lang......
