Two thousand years ago, there was a tragedy that made the world change drastically, it was like a disaster sent down by God from the sky to destroy humanity and the entire universe.
At that time all humans on earth had given up hope, and gave up on fighting for their lives, although there were some humans who continued to fight but still what they were fighting was a form of devastation itself, so at that time even if all existing humans united it would still not achieve even a little victory, that's how cruel the reality was at that time.
Exactly 2060 years ago, a horde of demons and angels descended from the sky, fighting and destroying the earth and its contents.
The scars of the battle are still visible to this day, the geographical shape of the earth has changed and several countries were destroyed at that time, all of which are still imprinted.
For no apparent reason, the demons and monsters came to attack the earth and killed most of the human population of millions, as well as the angels who descended with the same number.
They fought, slaughtered, killed each other in the sky, on land and even in the sea.
The sea was full of blood, the land was full of corpses and the sky continued to be pitch black for years, emitting acid rain with radiation that melted the skin of humans and animals that touched it and made any plants die.
In that dark period, mankind did not dare to come out to the surface, they were forced to live in the ground with very miserable conditions and live in deprivation.
All the remaining human beings continued to hide in the ground, making settlements and surviving in the ground like rats.
Since none of the demons were aware of the existence of humans in the ground, and they were also preoccupied by the resistance of the angels.
Then, a few years later.
The angels stopped fighting the demons, and the demons became more and more free on earth.
During times of war, humans always rely on angels who at that time sided with humans and fought the demons, but that only lasted a few years until the angels stopped coming down from the sky and let humans be eliminated by the remaining demons.
No one knows why and why the angels stopped coming down and saving humans.
Was God at that time no longer in favor of humans? Are angels tired of fighting the demons or is this all God's will?
No one knows the answer, but clearly all the history that has happened two thousand years ago is still recorded in a book belonging to someone who continues to hide in the ground all his life.
Once again, humans are plunged into despair, at first they still believe in the miracle of God and believe in angels will eradicate all existing demons.
But, in the end, no one wanted to help the weak race that could only hide in the ground and do nothing.
Even god is refusing to help mankind, so who will humans turn to for help?
No one.
Humans had to save their own race, they had to fight to save themselves and eradicate the demons, that's how humans thought when they were stricken with despair at that time.
Then, the miracle that mankind had been waiting for happened.
A person in charge of collecting foodstuffs from the surface suddenly caught fire but did not die.
Or rather, he burned himself, and then he controlled the fire that burned him.
This phenomenon will be called the Magic Atoms in the future.
When angels and demons fought on the surface in the past, they contaminated the air on Earth with a new compound called the Magic Atom.
The compound was carried by angels from heaven and carried by demons from hell, since then the air on earth has been filled with magic atoms and everyone who breathes it will be contaminated by magic atoms.
At first there were some people who managed to survive and then could control the magic atoms, but at the same time there were also some people whose bodies rejected the magic atoms and eventually died of brain cancer.
The humans who survived the incident were called the first generation of wizards, or the generation of saviors who fought the demons.
Then from that incident, all the remaining humans united and fought against the devil using magic.
But unfortunately humans still lost, because demons are more reliable in using magic, and their numbers are greater and their bodies are bigger and stronger.
Very different from humans who are fragile and not very reliable in controlling magic atoms.
Because of this incident, the humans who survived the war continued to train and study underground for years to master the technique of controlling magic atoms.
Then, once again a miracle happened.
After the miracle of magic atoms, there is now another miracle: the rain of transparent stones.
At first, people thought that the stones were dangerous because they might have been produced from sea water and clouds contaminated with nuclear radiation.
But at the same time, the demons avoided the stones, as if they were afraid of being hit by the stones coming down from the sky.
Like a miracle revealed by God to humans because of the mercy and determination of humans to fight the demons alone, they finally found a weapon that could kill the demons.
That is, Quantum Dust.
The mysterious mineral stone is transparent, but reflects rainbow light when placed near sunlight, and can circulate certain magic atoms in it.
Humans then crushed the stones into dust and made weapons and ammunition from the dust.
On that day, a glimmer of hope for humanity to be free had emerged, a weapon of demon annihilation.
Once again, humans were united and determined to fight the demons that had kept them underground for years and reclaim the freedom that had been taken away by the demons.
The final and final war in the history of mankind.
The remaining 900,000 humans were united and led by the 7 strongest commanders of humanity at that time, 7 people with extremely high magic power and talent, they also each held a weapon made of Quantum Dust.
Weapons made of Quantum Dust will eventually be called Quantum Artifacts in the future.
The 7 armies, each containing 100 thousand humans, then attacked the demons gathered in the demon king's castle and there was an all-out war there.
Then it ended with the victory of mankind led by 7 heroes, although the casualties were so many that the remaining soldiers at that time were only a quarter of the total army, but they managed to kill the demon king and eradicate all the demons on the surface of the earth.
It was a triumph for mankind, the first time in history that humans had won against the demon army that had kept humans locked up in the ground.
The place of the demon king's castle, in the future known as the Kingdom of Aurelius or the land of the victory of the heroes, and became the residence of the heroes and humans who at that time participated in the war.
In the future, the names of the 7 heroes who managed to save humanity at that time will continue to be remembered by humans for thousands of years in the future.
And there the story ends.
"Do you think that story is real, Violet?"
A middle-aged man in a white suit as if to reveal himself as a research doctor was reading a history book in a room full of surgical equipment, and there were many monitors with pictures of boys and their families in a house located on the edge of the Aurelius Kingdom.
"I don't know, I don't really care about history that has long passed, after all we can ask the person directly now."
Beside him was a woman with a height of about 170cm and distinctive purple hair along her back, the hair was tied up like a ponytail to make it easier for her to do activities in the cramped room, she was wearing a white suit following the man who also seemed to be a research doctor.
"You should learn more from history you know, don't be lazy."
"True enough, but does that have anything to do with my current job?"
"No, that's not what I meant."
"So what?"
"Yeah, never mind."
"Instead of that, how is the android search progressing?"
"Ah, you mean that android with serial number E-880?"
"She's been missing for a long time hasn't she? Are you not trying to find it?"
"Don't worry Violet, there's a tracker inside that android."
"Then why didn't you immediately mobilize the troops to retrieve it?"
"Calm down, don't rush."
"But there's something valuable inside, right?"
"That android is my masterpiece, I implanted a quantum artifact in it, there's no way I'm letting it go."
"Ah, that's right, it can behave like a human, right?"
"That's right, I made it especially for Mr. Aquila, even the appearance is similar to his ex-wife when she was young."
"Then why don't you just take it back right away?"
"I said calm down first, Mr. Aquila didn't rush to ask for it, after all I found information from that android recording."
"What recordings?"
"The kidnapper can regenerate, that's great isn't it?"
"Regenerate? Is that real? Aren't you looking at it wrong?"
"That's why you're a fool! I told you not to hurry, in time I'll take back the android and the kid that can regenerate."
"Oh, as expected from Professor!"
"Well, for now you can keep an eye on his moves first, have you gotten information on his place of residence and family?"
"I have, professor."
"Then for now, let's just keep an eye on it."
"Yes, Professor Ryvolin."
"This is going to be a new discovery that could change the future of mankind," continued the professor as he looked at his monitor depicting a boy and his family.
