A hundred thousand years later.

Demon Continent.

In the eerie silence of the night, on a vast expanse of grassland, a warrior stood in the middle of a mighty spell carved on the ground.

There were skulls, bones, blood, skin, and even actual heads and body pieces of humans scattered around on the spell.

The red hair of the warrior fluttered with the wind and so did her black robes as she stood with a lifeless expression in the middle of the spell.

"In shadows deep, I call your name,

From fiery depths, arise, and claim.

This pact we forge, our destinies entwine."

The girl chanted calmly and slit her wrist, letting her blood drip down on the spell.

Her crimson blood flowed to all parts of the spell and lit up, casting a crimson glow in the dark night.

A loud cackle was heard in the next few seconds and

"HAA!" The warrior heard a gasp and two dark claws immediately grabbed her neck.

A being appeared behind her back. A being so evil, without even glancing at him, the warrior felt chills down her spine.

A being so strong, his existence pressured the domineering warrior's legs to tremble.

Yet, the warrior stayed emotionless and on her feet, calm and unbothered by the claws grasping her neck.

She showed no weakness to the devil, for there was none.

She had lost everything there was on the very day she was born. She should've been long dead, but she persisted, persisted because of a promise she made to a certain man ages ago.

Her life had been anything but good, even though the man had blessed her.

She wandered around from place to place, a lone sheltered girl's life was difficult in the open. Fate wasn't kind to her and she had been thrashed, beaten up, and eventually sold as a slave to a noble house.

What would've happened had the man handed her to the Emperor, happened in this noble house.

She was abused repeatedly and finally when was weak enough, thrown on the streets.

She still survived after this.

This time, she looked no less than a cheap whore as she had aged into a mature woman.

Thankfully, she had awakened her Magic Core on time. She was hungry in the noble house this one time and since she couldn't find anything to eat, she resorted to eating the shrubs growing around the noble house, and accidentally consumed a white flower.

This led to her awakening which went without any problems. She was a normal mortal's child and suffered no problems during her awakening as there was no foundation built.

Her magic core's area was as tiny as it could be and she was the weakest of the weak. But thankfully, she had awakened.

On the streets, she begged for food and shelter.

A demonic cultivator found her and having a keen eye for finding diamonds in a coal mine, he took her in.

He then did what any demonic cultivator would do, broke her further.

But before breaking her, he made her stronger to have her resist properly and not break under him.

When she was strong enough and he started toying with her, he quickly got bored as this useless thing didn't scream or writhe in agony.

He threw her out and once again, the girl was on the streets.

She was sort of an immortal now and didn't need anything to eat for survival.

She just lay dead at the side of a street, completely giving up on life.

She wasn't a crybaby anymore and she had not a single ray of hope. She was tired. She wanted to rest.

Eyes closed, Keith decided to sleep, caring not for the position or place she was in.

Many days passed with not a single soul showing pity to her.

But fate had finally listened and shown pity, as a short old man found her alive and took her in.

Keith lay in a lifeless state for many months under the old man's care and finally, she found some warmth.

She woke up and became a disciple of the old man who trained her and turned her into a warrior.

She eventually repaid the debt of the old man by saving his life thrice, and parted ways, not wanting to be under anyone's care again.

Keith journeyed across the eight continents and through a series of arduous challenges, turned into a mighty warrior. Though, there was no happiness whatsoever in her life despite the many breakthroughs.

Life became better but she gave no care. There was not a single thing that she was attached to and not even the slightest of motivation to live.

She was a living corpse and just lived because nobody had killed her yet. She couldn't die on her own because of the promise she made to a certain someone. She even forgot who it was and just remembered the promise.

Eventually, after all the struggles and getting strong enough, she had no drive to defeat the Emperor and decided to do a sort of suicide ritual. If she succeeded, her revenge would be taken, and if she failed, she would die. As simple as that.

This summoning spell she casted was to summon a powerful Devil from the vast expanse of cosmos. It needed nothing but a strong will from her and a few other things.

The stronger and mightier a being was, the easier were their ritual; for the summons don't call them, but they themselves choose their summoners.

The Devil Keith had called, a mighty being, as he clasped her neck, he didn't kill her, but tested her.

As she showed no signs of movement or said anything, he appeared in front of her and peered deeply into her lifeless crimson eyes.

The vicissitudes of life, the struggles, the experiences, they were etched within the lifelessness and made the Devil frown.

A vile, corrupt, and filthy being like him, he frowned.

There had not been a single person in the cosmos who had made him frown like this, but this woman, without even saying anything, conveyed everything through her hazy gaze.

"In front of the cruelty of man, even a Devil like myself pales," he muttered softly.

Not wanting to see her precarious condition anymore, the Devil hit the girl's neck and picked her up in his arms.

He chuckled like a Devil would and said, "So this is what they mean when they say that the way of the heaven is just, huh? Making even an almighty devil like me bend truly a laughing matter."

His gaze then fell on the sleeping woman. He smiled and continued, "well at least you're profiting now after all that suffering. Your body is filthy, so are you, peasant."

The Devil put his hand out and casted a spell. The magic circle lay still in mid air in front of him.

The Devil put her on top of it and continued with the same smile, "I'll have you reincarnate in a much better physique a Devil's physique, one that has the potential to reach my level. I do not care if you choose to live a life of peace and quiet or become the strongest, all I want is for you to do one favour for me. What it is, you'll know once you reach a certain mark."

The Devil then started writing a few things on the woman's hands. "This is your Destiny I am writing. The Destiny to lead a good life, one not of suffering."

Once the Devil finished, he broke both his horns and smiled widely. "If you wish to, you'll become the strongest Devil other than me and shake the heavens, take revenge for what it did to you and make it cry."

The clouds above the Devil gathered around, a tribulation was about to occur.

"HAHAHA! SOMEONE'S ALREADY ANGRY!" The Devil shouted.

He didn't waste more time and immediately hacked the two horns into the woman's heart.

He looked at her with an evil smile and said, "don't disappoint me. This is a gift and I don't expect anything in return, but being a Devil, it just doesn't sit well with me to do things for free. Still, consider this a choice. It's up to you to choose your other Destinies."

ZAPPPP!

A lightning striked the heart of the Devil and made him vomit blood. He still smiled widely and looking up in the sky, said, "do better. This isn't enough to kill this expert."

The world seemed to be angry at the Devil and the sky roared angrily.

Another bolt of lightning came the Devil's way, but to his surprise, shot at the heart of the woman, activating the spell the Devil had put up and sent her into reincarnation.

Her body was destroyed and her soul went to look for a new one.

Just like that began a new cycle of life for this suffering soul, who, even at the end of her life, suffered by getting between the crossfire of an expert and the heavens.
