History (Modified)

In a large library, there was a 4-year-old boy sitting on the floor surrounded by books. He had light blue hair and blue eyes, if you looked him in the eye you could see little electric sparks dancing in his irises, that boy is Henry or was, now he goes by the name Eduan. He had a book in his hand reading with a concentrated gaze as he thought.

'It's been 4 years since I reincarnated in this world, in these 4 years I discovered that I reincarnated in the DxD world with small differences, for example, more than 4000 years ago apparently appearing out of nowhere came 9 of the great heads of 10 families, from the Tower of God , and several years later the head of the family Khun and Zahard appeared as well.

Apparently what appeared were not the real ones, but the data that were in the hidden stage of the train, soon after being deleted by the young Zahard's data, the 9 heads of household appeared here, initially shocked, began to settle, at first it was difficult for not seeing shinsoo, but the head of the Po Bidau Family invented a method that consists of filtering mana, oxygen, life force, among other energies, and transforming them into shinsoo, wherever they went around they became shinsoo, so despite there is no shinsoo in this world, they can use it.

And they realized something, here they could continue to evolve, they trained and got stronger and stronger, until they found out about the supernatural, eventually they collided with some pantheons and factions, starting to make names for themselves in this world.

Eventually they began to settle down, each forming their own family, having many children, with the exception of the head of the family Yeon, who was a virgin, to form her family, a friend she made when she came to this world called Ilarde, received her surname and blood, and acts conceiving children for the Yeon family.

150 years after they settled, Khun Eduan and Zahard suddenly appeared, with the exception of Head of Family Arie everyone else was angered by Zahard's appearance, and they only settled down after Khun Eduan talked to them. Khun Eduan and Zahard quickly learned Po Bidau Gustang's method of using shinsoo, and they also settled down.

Khun Eduan easily formed his family, having many wives and making many children, while Zahard formed his kingdom with the 10 families below acting as "nobles", the Supernatural Factions around the world called them 'Holy Humans' because of the shinsoo that it's akin to holy power and divinity, with the 10 Great Families getting the name 'The 10 Great Families of Saints', and the Heads of Households and Zahard getting the name 'Holiness' because of their changed race, after advancing far above humans.

They continued like this, participating in wars with other factions, increasing their forces, enriching themselves, until 600 years ago they decided to leave this world, before leaving they shared some of their shinsoo, the putting it with a command, which they one day activated when the children called "heirs" were born, clearing the lineage and increasing the potential and talent of their descendants, so that's what happened when I was born.

It seems that the only one who left nothing was Zahard, he left without leaving any descendants or heirs, so the 10 Great Families are separated, some allied with each other, while others not...'

He continued reading until he stopped at a paragraph, and was shocked by what was written.

'It's written that 1200 years ago Zahard and the Heads of Household got together and made a big tower with 124 floors, where time and space are different from here, it seems like there time passes 20x faster, they open every 10 years, and send the youth of each family to pass through the floors, those who fail to pass the 124 floors in 400 years (time inside the tower) will be expelled from their respective families.

And those who pass are called true family members, and gain many benefits.'

"EDUAN, EDUAN, where are you?"

A man with light blue hair and eyes comes screaming into the library, snapping Eduan out of his stupor. He was Eduan's father, Khun Aguero, son of the current head of the Khun family. Eduan was very shocked when he learned that his father, who didn't look over 25, was already 346 years old, and his mother, who didn't look over 20, was 214 years old.

He found out that his father and mother were actually Siblings, apparently Incest in the 10 Great Families is very normal, each family is extremely proud, not allowing their children to marry someone outside. His mother's name is Khun Maria, she left the tower recently, and married his father and within 3 years of marriage they had him, who turned out to be Khun Eduan's heir.

"I'm here daddy"

Eduan quickly waves his hand, for Aguero to notice his presence. Aguero's gaze quickly shifts to his son's location, he walks quickly towards her as he speaks.

"You know today is the start of your training right?"

"Yes"

"Well, come follow me to the training room"

"OK"

Getting up and placing the book in his hand on the floor Eduan quickly follows his father. When they arrive in the training room, Eduan shows a slightly shocked look as he comments.

"Shinsoo density is higher here"

"Of course, this is the training room for the main branch of the family, it was personally made by the Great Ancestor, there are many modes, gravity modifier, increasing the density of the shinsoo to increase your resistance against it, among other things."

Aguero responds with a touch of pride in his voice.

"Alright, go change"

3 minutes later~

After changing Eduan quickly follows his father into one of the sessions in the room and sits in one of the chairs he was standing on while listening to his father speak.

"Since you were 3 years old you've read a lot of books, so you probably know that the Great Ancestors of the 10 Great Families don't originate in this world, so we'll be talking about some of their achievements as soon as they arrived here, I'll tell you things that are not in the books"

Agueros speaks while closing his eyes as if remembering something, he opens it and continues his speech

"A long time ago, two of the Ancient Great Satans tried to get the 10 Great Families to participate in the Great Holy War only to be stopped by the former Head of the Ari family alone, even though he was badly hurt in that battle she won them both alone. "

"After that, the Yeon Family Leader who was a great friend of the Head of the Ari family, knowing that his friend was injured became extremely furious, and attacked the underworld, decimating a huge amount of demons that were burned without leaving even dust."

"In the Great Holy War 5 of the Great Families participated, each completely shocking every faction around the world, the Yeon family burning everything in sight earning the family nickname of the 'Incarnations of Fire', the Head of the Family Tu Perie showing their great intelligence assembling various strategies on the battlefield, the Po Biuda Family building various weapons and medicines that could heal even an arm instantly."

"The Eurasia family showing an absurd control in the shinsoo flooding several armies, the Hendo Lok family showing an absurd defense and resistance, even taking big attacks they could easily get up."

"And lastly the Lo Po Bia Family, the former head of that family did something absurd during the war, he controlled the two Celestial Dragons to fight for him, causing shock and fear in various factions."

He speaks in a deep voice, after breathing a little and drinking water, he is now shaking a little.

"While the war was going on, in the Greek Pantheon, Zeus the God of Lightning, falling in love with the beauty of the Former Head of the Ha Family tried to force himself against her, angry and with little patience she invaded the Greek Pantheon defeating more than half of the Gods from there alone, with Zeus included."

"It is said that she deeply crushed Zeus' genitals, bringing horrible pain to him, even though he was healed, he was traumatized, so much so that when he meets someone like her, he covers his genitals shaking deeply, and apparently she doesn't would have stopped if one of the Heads of Households had stopped."

This made Eduan, who had been standing there listening to everything, shiver slightly as he thought.

'I heard that the former Head of the Family Ha, was aggressive and impulsive, but that went beyond aggressive and impulsive, it's more to cruel and crazy.'
