Ten years ago.

At that time, the bunker had only been built for a few years, and it was almost rare for ordinary humans to see it, except for elusive hunters.

And a number of cyborg cities such as Sky City have just emerged as a 'fashion' of captive human slaves. In order to meet their enslavement plans, and since Habitat 021 is the only place they know of where there is human activity, they use Habitat 021 as a fixed hunting range.

After all, Tessis, one of the ancient pioneers at that time, was still guarding Habitat 021, so those robotic cleaning teams only dared to wander outside the city, looking for lone humans.

After experiencing the big bang, the circle was successfully transformed by Uncle Chris.

Having lost her parents, she decided to go out and see what the world was like.

However, not long after she stepped out of Habitat 021, she was spotted by the cleaning team that happened to arrive.

Anna is the captain of the cleaning team.

Because the circle was quite beautiful at that time, she became the target of a group of robots at the moment.

Most of the members of the clean-up team have not suffered from human slavery, and their hatred of human beings has reached the point where it cannot be resolved.

Anna, on the other hand, is an exception.

The human couple who bought her are a suave Kochi couple who both hold professorial positions at the Human University.

However, due to physical reasons, they have no way to wrap their children around their knees like ordinary people.

Simply, they treated Anna as their child.

On the first day of Anna's activation, the human couple solemnly told her: You are different from others, you are a gift from God.

Since then, she has taken care of her in every possible way, as if she were her own daughter.

In such a family, Anna is also gradually perfecting the construction of her personal worldview.

Coupled with the influence of her 'parents', she feels that robots and humans should be equal, and have all the rights and obligations of independent individuals.

At her insistence, her parents created a human 'head' for her and equipped her with a full simulator to live in the world as a 'new human'.

However, with the advent of Chinese New Year's Eve, the world in Anna's eyes, the worldview she had worked so hard to build, collapsed!

The human couple turned into a pool of blood in front of her, and the warm little home that was carefully decorated became a satanic paradise!

Everything was completely different, and Anna couldn't understand why her fellow cyborg would do such a thing, given that the family around her had always been warm and cozy.

Immediately, the city in the sky was established, and the 'pampered' Anna also became an 'orphan' and was naturally taken back to that place where there was no temperature.

Here, she really felt that there would be two faces in the world.

Anna, who yearns for freedom and equality, has completely become a vassal of authority in this cold, orderly, respectful and orderly city.

After all kinds of humiliation and bullying, it took her several years to learn how to survive in this city that was incompatible with her.

To prove herself, she joins the army of cyborgs.

Relying on the super body material given by her 'parents' and the computing level far above ordinary people, she followed the army of Sky City to conquer countless robot cities that coveted Sky City.

Eventually, he climbed from the bottom of the undignified society to the position of an admired officer.

The devil knows how much she has suffered in this short period of time, if she will cry, she must have dried up, right?

Anna was allowed to live on the fifth floor by Sky City, where the low-ranking officers lived, where she was given a house of her own.

In that small room, Anna patiently cleaned up her home, relying on the materials in her database, trying to restore the home that had long been reduced to ashes.

After living in peace for about half a year, a paper order was delivered to her door.

As the Hunters' Guild grows rampant, they unscrupulously sabotage the actions of the robots on the ground.

Under Phoebe's leadership, all of the robot cities except Foothill City have implemented a cleanup plan.

The day Anna met the circle was her first cleaning mission.

Due to her outstanding achievements, she directly served as the captain of the cleaning team.

Probably because of her 'family', Anna has always had an inexplicable affinity for humans.

At that time, Huanhuan had just walked out of the No. 021 habitat, and she had no idea where she was going or what she could do.

Just ten kilometers from Habitat 021, Anna's cleaning team encountered a circle.

After the transformation of the circle at that time, it already had a strong combat capability.

She simply and neatly eliminated the cyborg soldiers, but Anna was in front of her.

Anna didn't intend to embarrass this beautiful human girl, and she only planned to go through the motions and leave in a circle, but she didn't expect that she would actually deal with all her soldiers, which also made Anna have to deal with this young girl herself.

The two struggled for a while, but eventually lost due to the lack of experience in the circle.

Circle was crushed to the valley by the robots, who would have been the first human to eradicate after Anna's clean-up plan.

Anna still remembers the circle of eyes.

The two bright eyes on the face of this handsome girl covered with mud were exceptionally clear even on the surface of the yellow sand.

The look was full of confusion, but Anna saw that it was extremely determined.

These are clearly two things that are mutually reinforcing, but they appear mysteriously in the eyes of the circle.

That's the look! Anna thought to herself.

Isn't that what you are?

This was the look in her eyes when she first entered Sky City.

I don't know where the future lies, but I firmly follow the direction of my heart.

So, Anna put down her weapon and returned to Sky City with the circle.

Because of her dereliction of duty, she was disqualified from living in the upper city and was thrown into the bottom three floors of human slave life, along with the circle.

The circle is nominally Anna's slave, and slowly they get along, and they become good friends who talk about everything.

It was also their only friend to each other.

When they first arrived, the two of them were quite attractive, and they must have been coveted by different gangs.

They had spent a long time in the three floors at the bottom, and they had all seen the dirtiest and bloodiest scenes. But under Anna's protection, the circle has not been disturbed by others, showing people as master and servant outside, and when they return to their nest, they will be called friends again.

And so it went on for a whole year.

Gradually, some of the robots discovered the little secret between them and sued the Thirteenth Floor Slave Society.

That is, from this day on, the circle lived on the thirteenth floor as a real slave.

At first, Anna tries her best to protect the circle, but the more she shows her protection, the more cruel the circle will be.

Eventually, someone pushed the hoop into the ring.

Flowery girls, touching people, cross-racial secrets, these keywords are precisely the stimulants of those low-level residents who have nothing to do, and more and more robots are coming to see what is going on.

On the first day of the ring, the entire thirteen-story alley was empty, and the ring hall was packed.

With the referee's whistle, the robots in the audience all waved their arms excitedly.

However, in the next second, the audience became silent.

With just one punch, the hoop knocked out the sturdy male slave next to her, who was clamoring to tear the hoop apart before the fight.

And Anna also turned a lot of money with a unique odds of 500,000:1 in history.

Immediately afterwards, the circle became a legend for a while with the proud result of 100 consecutive victories but not to death.

After having wealth, their lives were not as smooth as they imagined, and the circle of fame and Anna, who became rich overnight, became the target of public criticism again.

All kinds of gossip kept reaching the circle and Anna's ears, and in the face of more and more ugly words, Anna finally couldn't help but take action.

It took her a month, day and night, to conquer all the robots on the thirteenth floor one by one with her fists.

And the circle is becoming more and more active in the ring, and under her angelic face, there is a demonic body.

The circle even broke the boundaries of race, and she even won praise from the cyborg. Of course, a large part of the cyborgs who praised the circle were subservient to Anna's fists and feet.

In this way, one is a human slave who has earned the respect of the robots, and the other is the robots who single-handedly take on the entire low-level city, and they have used their actions to win a short year of peace.

The circle also took the opportunity to quit the ring and used Anna's money and prestige to start a bar business.

All the taverns on the thirteenth floor, the fifty percent taverns on the twelfth floor, and the ten percent taverns on the eleventh floor were all in Anna's name.

Recently.

In the fourth year, the circle was pushed into the ring of life and death.

To this day, Anna has not figured out who did this.

In terms of force, how can these human slaves, who are so weak that they can't have enough to eat, be the opponents of the circle.

But Circle and Anna agree that killing humans is what they don't want to see.

To this end, Anna spent a lot of money and energy to get around, but to no avail.

No matter how strong one person is, he can't resist the rules of the whole world.

In the end, the circle still stood in the ring of life and death.

Before the start of the game, Anna and the circle discussed countermeasures for a long time, and decided to use silence to fight the world.

As soon as the race began, the hoop became the target of public criticism.

Everyone understands that if they don't kill the circle first, they won't have a glimmer of hope for life.

It doesn't matter if the circle kills them or not, it's the same.
