Hundreds of years ago, the earth was devastated and reduced to a wasteland.

The oppressed underclass overthrew the tyrannical rule of the chaebol and finally allowed the land to recuperate.

A long time must be divided.

After hundreds of years of stability, scientific and technological achievements have exploded, and with the uneven strength, global wars have broken out.

Once again, the regions were divided, forming countless countries and isolated cities.

The war lasted for ten years before ending with the formation of a coalition government in the most powerful autonomous regions.

War has torn apart countless families, displaced billions of people, and seized the opportunity for many to thrive.

The wealth and force of the major corporations are directly under the control of the coalition government, especially the homeless people in the slums, who have become the experimental subjects of the company's random arrest.

Under these circumstances, rebel groups emerged, and the government and major companies began to gather mercenaries to suppress them.

This confrontation has been going on for many years.

It all stems from the appearance of the prosthetic.

The war for federal integration and the campaign of repression have left countless soldiers and civilians maimed in mourning.

At first, the advent of mechanical prosthetics allowed people with disabilities to take care of themselves and gave them hope for life.

With the advent of mechanical organs, this kind of blood type can fit perfectly into the human body's organs, so that many seriously ill patients can live like ordinary people.

Later, the use of prosthetic weapons and organs to replace unhealthy parts of oneself became the mainstream of medicine.

In the new era of the destruction of civilization, the replacement of prosthetic weapons has developed into a trend, allowing human beings to break through the limits of the body, overpowering the voice of the "parents of the body's hair and skin".

Slowly, the situation began to spiral out of control, and the criminals gradually replaced the limbs, torso, and skull with mechanical prosthetics, and the electronic components gradually replaced the role of the brain.

What's even more terrifying is that under the rapid development of science and technology, the simulated skin and hair make it impossible to distinguish the difference between synthetic and natural people from their appearance.

The "humans" who replaced all of their limbs, torsos, and heads with mechanical prosthetics and brains with electronic components also have a new name: prosthetic synthetics.

Some people believe that prostheticization will bring destruction to human civilization.

Some people feel that this is an opportunity for humans to break free from the shackles of natural death and become a completely new species.

There are also people who insist that the human after the replacement of the prosthesis is just a pile of electronic components, and although the person's behavior and memories are the same as before, he is actually dead.

The so-called "life" of a synthetic person is just a mechanical intelligence analyzing and simulating his behavior during his lifetime, so that human thoughts are reduced to data and become binary programming composed of "0" and "1".

Whether the guys who have been replaced by machines with physical bodies or even brains are still human or not, no one can say clearly.

Synths began to integrate into human society, and their numbers have proliferated, reaching four percent of the world's total population, and they can be found in all walks of life.

Thanks to the mechanized high-intensity body, their work level is also better than that of ordinary people.

Five years ago, an European synthesizer announced his candidacy for president, a move that caused an uproar.

The mechanized body makes the synthetics no longer have the metabolism of normal humans, they do not have to be affected by diseases, their bodies have almost no weaknesses, and they have a long lifespan.

If the synthetics are made to become the leader of the human race, it means that the ruler of this society will become a human being with no life limit.

The world of normal human beings, for them, is more like a game.

This is undoubtedly a terrible move.

At this juncture, there was another murder of an intelligent housekeeper that shocked the world.

As a result, the voices of opposition to the intelligent machine reached its peak, and the antagonistic emotions of the two sides were brought to a climax.

A major war known as the "Battle for Freedom" ensued.

The synths were defeated after all, and they were sent to concentration camps in batches to be dismantled and recycled.

After five years of cleaning, most of the synths were cleared, except for a few who hid as fish that slipped through the net.

In order to maintain the free will of human beings and the order of the natural evolution of life, the research of mechanical prostheses and intelligent robots is expressly prohibited.

The new decree promulgates that those who have been fitted with mechanical limbs or mechanical organs, equivalent to intelligent robots, are defined as intelligent machines that threaten social security and exist illegally.

Relatives of prosthetic people within three generations were forbidden to work in enterprises and government departments, and were deprived of the right to referendum.

There was renewed outcry against disabled people who had been able to regain their freedom thanks to technology, soldiers who had lost limbs to keep the peace, and seriously ill patients who had to use mechanical organs to survive.

But they are in the minority.

The harm and fear that synths once brought to ordinary people were transferred to these same people who had changed their prosthetic weapons, and they were ostracized by mainstream society, reduced to the lowest level of society, and became a group of humanoid creatures with no human rights and could only hide in Tibet.

As a result, synths began to rebel! Make a riot! Become a thug!

It's a chaotic time! It is also a time of opposition! It's a crazy time!
