In Biblical mythology, the figures of Beast Emperor 666 and Satan, Beast Emperor 666 and Samael, Satan and Lucifer are often confused with one another.
Apart from misrepresentation, this is also for the purpose of myth assimilation.
Each mythical creature has its own 'position', which is the so-called divine seat.
For example, if the Underworld were to become a socialist system, after a few generations, the life forms of demons might change.
Similarly, the same applies to angels.
Only the Fallen Angels are unaffected, because Fallen Angels inherently exist between angels and demons.
They possess the power of light, yet also symbolize corruption and evil.
Their very definition is ambiguous, so naturally, they do not undergo significant change.
If Beast Emperor 666 and Samael were to be fused, myth assimilation would occur, truly integrating it into the Biblical Pantheon, rather than being vaguely hinted at in the Bible as the existence of some monster~
Based on this, by further fusing the concept of Satan, the Evil Tree can take shape.
Of course, this is just one factor.
Because Beast Emperor 666 and Samael have a basis for fusion, that's why Rias thought of doing this.
In this world, Beast Emperor 666 is an independent dragon, while Samael is the malice of God, possessing special effectiveness against dragons.
If these two concepts are fused together, it could create a new Beast Emperor with intelligence and self-awareness!
The malice of God—in the original work, Issei Hyoudou merely came into contact with a trace of it and died instantly.
If not for his dream attracting the attention of the Great Red, who then remade his body, Issei Hyoudou would have died outright.
He wasn't a true dragon, merely a host for the Red Dragon Emperor, possessing a dragon's power.
Moreover, to be precise, this thing isn't just effective against dragons; its basic attack power alone is enough to annihilate gods and demons.
Sub-Dragon God?
With the life form and concept of the Beast Emperor, plus the Dragon's Poison, it might just become a Super Dragon God.
If integrated with the system of the Evil Tree, further advancement is also possible.
Is this considered an artificial experiment at the 'Three Evil Gods level'?
"Stay here for now."
Rias created a magical device to contain the concept and fused Beast Emperor 666 into it.
Afterwards, Rias left the Crimson World.
Glancing around, although because the Netherworld is different from the material world, there were no visible signs of destruction.
But Rias could directly perceive the fluctuations in the world's rules, so she could sense that this area had been disrupted.
Rias's move wasn't something that could be displayed in the material world in the first place; its mere appearance could disrupt Earth's own balance, and its very existence might destroy the planet.
Even here in the deepest part of the Netherworld, a place abandoned by the world and forgotten by life, it would remain chaotic for a long time.
The Netherworld was already dangerous enough; normal life could be swallowed by it at any time. Even the Sephiroth Graal only those who have reached the level of gods and demons can remain unaffected.
And now... even Transcendents wouldn't last long here~
"Whatever, not my problem."
Rias shrugged, then with a thought, crossed several layers.
The Netherworld isn't just a single layer; its spatial form is very peculiar. Even the Flugel's mastery over space makes it difficult to move freely here~
But Rias had conducted considerable research on the Netherworld itself, so naturally, she wasn't included in that limitation.
The Netherworld isn't a normal world to begin with. Given its environment and structure, so different from the material world, how could Rias not study it~
Soon, Rias reached the surface layer of the Netherworld, then crossed its boundary and returned to the Underworld.
"There's still time. First, go to Hell and retrieve Samael."
Rias narrowed her eyes slightly, then headed towards the deeper layers of Hell.
This time, using spatial movement ability, it only took a few seconds to arrive here.
Generally speaking, Pantheons have their own jurisdictions, but the greek mythology's Underworld is special.
Most beings in the world, after death, go to the greek mythology's Underworld.
Stray souls or individual souls might fall into the underworld, as well as those people who made pacts with demons in the past, with their souls as the price.
Ordinary people living in the present world, if they have merits, will enter the Pure Land controlled by Buddhism.
Of course, believers of the Biblical Pantheon are guided to Heaven. So they aren't included.
The reason for this is the mythological competition of ancient times.
Hades is a Transcendent, one of the world's top ten powerhouses, thus allowing greek mythology to control the deepest part of the Underworld, the destination of souls, occupying a crucial position regarding the dead.
Therefore, many deceased beings are under Hades's control, and from them, he has built an army composed of the dead.
This is an army of the dead, distinct from his subordinate Shinigami, used purely as cannon fodder, available in limitless numbers.
The reason the Biblical system didn't gain control of the underworld is that the Biblical Pantheon emerged later than greek mythology, after all, the various Pantheons weren't born at the same time~
Later, when the First Generation Lucifer fell, he might have been wary of Hades, so he didn't cause trouble for him.
Anyway, the underworld is vast, and moreover, other Pantheons wouldn't hand over the destination of souls to demons.
"Tsk, such a waste to leave it to Hades."
Rias muttered in complaint.
The dead stored since ancient times, although most don't possess strong combat power, are endless in number, which is terrifying.
Without strategic weapons, it really wouldn't be easy to deal with.
But again, it has nothing to do with Rias. That guy Hades will be dealt with sooner or later.
Hmm... might as well leave this task to the Evil Tree.
Perfect, the Evil Tree needs a base anyway. Let it conquer the Underworld at the deepest part of the Underworld~
Casually assigning a task to this 'ambitious schemer', Rias didn't care in the slightest.
Rather than thinking about that skeleton's affairs, Rias's mind was now fully occupied with her own experiment.
She soon found the place where Samael was sealed.
Red fluctuations casually spread out, followed by an invisible crimson light forming, isolating the aura of this place.
In an instant, a black light shot up into the sky.
The seal was shattered, and a monster appeared before her.
It was a creature nailed to a cross. The restraints binding it were stretched to their limit. Restraints covered its entire body, rendering it immobile, and uncomfortable-looking text was etched on the restraints!
Its eyes were also restrained, with bloody tears flowing from the gaps.
Its upper body was that of a Fallen Angel, its lower body that of a dragon.
Its hands, serpent tail, every corner of its body—even its black wings were pierced with countless thick nails!
Just looking at it was deeply unsettling, and a chilling, horrifying coldness emanated from its form.
"Ooooooooooh────── Ooooooooooooooh────── Ooh...!!!"
The crucified sinner let out a bizarre cry from its mouth, baring its teeth as it spat out saliva mixed with blood.
Its cry was low and agonized, filled with suffering, envy, pain, resentment, and all other negative emotions.
Just from its appearance, one could tell it bore all the hatred of its executioners.
"The one who tricked the residents of the Garden of Eden into eating the fruit of wisdom, still cursed by the now-gone God of the Bible—the primordial sin, the 'Dragon Eater', Samael."
