As the two chatted, Sona's expression was extremely excited, chattering away to Rias about something.
Indeed, for children, any language is pale and powerless, because they cannot understand the profound meaning contained within words.
But a direct, sensory experience might be something they remember for a lifetime.
Was the scene just now beautiful?
Who could have known that those cute little animals, condensed from Power of Destruction, possessed more power than missiles once they erupted.
In terms of pure destructive attribute damage, the core's power even surpassed nuclear weapons.
Not only that, but even Sirzechs couldn't manipulate Power of Destruction to that degree.
Of course, condensing Power of Destruction into such scenes and animals was certainly possible. But to do it so smoothly, and to possess the ability for them to be touched without harming others, that was a power unique to Rias.
As Sona grew up, she would surely come to understand the deeper meaning behind that beauty.
"It's getting late~"
Seeing the sky darken and Sona's somewhat sleepy expression, Rias chuckled softly.
Happy times are fleeting, and soon it was time to go home.
"Can I come again? Lady Rias~"
Sona grabbed the hem of Rias's clothes and asked in a clear, childish voice.
"Of course."
Rias said gently, "You can come anytime you want~"
Rias liked children very much, especially cute, delicate little girls.
Their innocent appearance could help Rias relax.
Returning to her room, Rias picked up a book as usual and quietly read its contents.
Countless inspirations collided in her mind, forming new lines of thought.
Like the infinite, the boundless—
It was like walking on a road with no end, where there were still unique sights along the way.
"Feels pretty good."
Rias murmured softly.
"Bankai—"
Rias drew her Zanpakutō and said softly, "Hakai Hōteishiki Number Five: Beast of Destruction: Butterfly Dance."
The Zanpakutō vanished, transforming into a mass of dark red magic power.
The mass of magic power divided, continuously changing into numerous red butterflies.
Fluttering their wings gently, the red butterflies danced, disappearing from their spots with each beat of their wings.
Heavenly Transfer—
This was a spatial movement ability unique to the Flugel.
She had not only inscribed such a Magic Formula on her own wings but had also extended the technique to her Power of Destruction.
Butterflies composed of Power of Destruction should have had no life, but Rias applied the Flugel's life-giving Magic Formulas to them.
It specifically integrated concepts from parts of the Flugel's Magic Formulas, the Forest Spirit Race's core interference techniques, Rias's Hakai Hōteishiki, the existence form of the Zanpakutō, and various other ideas.
They lacked complete intelligence but possessed unique thought patterns, and more importantly, they contained Rias's will, capable of acting as Rias's surveillance cameras.
Each butterfly was equivalent to a subordinate life form created by Rias.
Undoubtedly, this already touched upon the domain of life.
Although, Rias was only using them to gather intelligence.
The Underworld was vast, unimaginably so.
Within it, demons, Fallen Angels, Shinigami, and even the hells of various mythologies, though not truly in the same space, existed in the same dimension.
It was like the Underworld attached to the Human World was like a large bubble, and within that large bubble were many smaller bubbles.
These were all part of the Underworld, but they contained the Hells and Underworlds of various Pantheons.
To obtain what she wanted, Rias needed to condense many butterflies daily and distribute them across various Underworld territories.
And not just the Underworld, but also the Human World.
Besides Heavenly Transfer, since the butterflies themselves were constructs of Power of Destruction, they would self-destruct if they encountered a crisis from which even Heavenly Transfer couldn't escape.
But it would still take a very long time to spread these butterflies across the entire world... "Magic power depleted, huh."
Rias stretched lazily.
The mass of magic power in her hand completely vanished, and the Zanpakutō reappeared in Rias's grasp.
Just the butterflies she had created now numbered in the tens of thousands, but her magic power was still insufficient.
So, she still needed to continuously train like this to increase her magic power... Physical training couldn't be neglected either~
Although part of it was intentional magic power consumption, the duration she could maintain her Zanpakutō's release state was still not enough.
Especially compared to someone like Vali Lucifer, who could maintain his Juggernaut Drive for a month, the gap between them was quite large.
This was probably the difference in magic power between Royalty and Nobility.
After all, only Rizevim Lucifer was the biological son of the First Generation Lucifer and Lilith; other Lineage Demons were created through Magic Formulas.
Before her life form reached the level of Transcendents, she was still considered a demon, so having a racial gap was only natural.
But correspondingly, her combat power was something Vali Lucifer couldn't compare to. This was the difference between active cultivation and natural growth.
Releasing the Zanpakutō meant unleashing its power and form, causing a significant increase in power, equivalent to Juggernaut Drive.
The corresponding consumption also increased. Because her internal energy was gradually becoming insufficient, Rias fused the forged King Piece into herself, but it still wasn't enough.
It could be said that Rias's base state had reached Maou-class. Releasing the Zanpakutō would further enhance this base, and Bankai would increase magic power consumption while allowing her to reach a level surpassing ordinary Maou-class.
If she used Bankai's special ability, Hakai Hōteishiki Number Nine: True Form of Destruction: Baryon Mode, she could elevate to the Transcendent Level, but the physical strain was immense.
For this reason, Rias modified her own body. That pair of red Demon Wings was the result.
That was the third stage of the Fusion Equation: high-density magic power condensed into crystals. The mass contained within might be on par with Sirzechs's.
So even without using Baryon Mode, she possessed the power to fight against ordinary Transcendents.
Hmm... If it were the disgrace of the Transcendents, Rizevim Lucifer, perhaps he'd get a beating?
The reason for using Bankai to create butterflies was also the difference between manual and automatic.
Directly investing magic power, followed by the construction of the Magic Formula, was much more convenient than manually constructing the technique herself.
Truly, humanity progresses for the sake of laziness, though she wasn't human... "Speaking of which, if only I could successfully complete the research on the element' subject."
Rias murmured.
Among the element given by Jibril, Rias placed a magic power crystal.
The element surrounded the magic power crystal, absorbing its energy.
Once full, a portion would grow, while another portion would split.
No wonder the Elementals was called 'life'. They were no longer just a manifestation of energy but truly sentient beings.
Although their sentience in this state was very weak, they would eventually become life in the truest sense.
Equivalent to the Elementals's offspring?
"If I could thoroughly research the essence of element and apply the Magic Formula to all the butterflies, they would be able to self-replicate."
