Perfectly controlled fusion, yet not merely fusion.
As is well known, fusion and fission release enormous power, their essence being mass defect.
Energy fusion is the same; both fusion and fission processes release vast amounts of energy into the surroundings.
But what if that energy were completely and perfectly controlled?
At the instant fusion is completed, expand the periphery of the energy sphere to a range one deems acceptable, then collapse it inward after fusion, reclaiming the released energy.
For the next use, the same method can be applied to perform energy fission.
A once-disposable strategic nuclear weapon becomes a recyclable weapon.
There is still loss during the energy conversion process, but compared to ordinary consumables, it's much better; replenishing the lost energy is far too simple.
This is one of the application methods of the second stage of the Fusion Equation.
Another method is to perform fusion on the energy within one's body, thereby fusing one's entire magical power into a higher-grade magical power.
At this point, Rias has already applied the Fusion Equation to herself. The lowest level of fusion slowly improves the quality of Rias's magical power.
Simultaneously, the lowest level has already reached the realm of the Transcendents.
If combat is needed, the fusion reaction can be instantly increased, thereby obtaining greater power.
Taking Rizevim Lucifer as an example again, he also counts as a Transcendent, merely the disgrace of the Transcendents.
Rias's usual state is similar to Lizevim's, but during battle, she can rapidly elevate to a level close to Sirzechs's.
"So easy."
Rias felt a bit regretful.
The resistance wasn't very great, or rather, there was no resistance at all. She had wanted an evenly matched fight.
In the end, it was just a test explosion.
Oh well, can't ask for too much.
Returning to the Gremory Family, Rias first went to Valerie's room.
After dismissing the maid taking care of Valerie, Rias approached Valerie.
Gently extending her hand, three Holy Grails emerged from Valerie's body, floating in Rias's palm.
"Eek?"
Valerie reached out, grabbing Rias's fingers, her face full of joy.
This child is very attached to Rias.
No, not just this child; this includes Gasper as well.
Although Rias prefers girls, the Sacred Gear on Gasper requires prolonged contact, so she has somewhat neglected this child.
"Sorry, I still have an experiment to do."
Rias thought for a moment and added, "Oh well, I'll just hold you while I do it."
Saying this, Rias took out a rocking chair from a subspace, held Valerie in her arms, and while rocking, examined the condition of the Holy Grails.
These three Holy Grails are not the ones from Valerie's body; they are Rias's magical devices.
Using technology to fuse the magical devices with the Holy Grails, allowing the power of the Holy Grails to flow within the magical devices, causing them to transform.
After roughly a few months, the magical devices reached the realm of 'liberation.'
The Sephiroth Graal split into three, and Rias took out three magical devices, forming a trinity of magical devices.
Both share the same origin, but one split into three, while the latter were three from the start, yet still connected to the other two Holy Grails.
The power of the magical devices is equal to that of the Sephiroth Graal; rather, it's like making a copy of the Sephiroth Graal.
Simultaneously, the artificial souls constituting the core of the magical devices contain Rias's flawless will.
Equivalent to a pure will entity not carrying any magical power characteristics.
The magical device: holy grail born from this foundation has extremely high compatibility with Rias.
"Other Sacred Gears aside, only the Holy Grail is an indispensable part of the experiment."
Rias murmured.
Under her manipulation, the three Holy Grails formed a triangular arrangement.
Power flowed through a layer of Power of Destruction before entering Rias's body.
Soon, the light of the Holy Grails stopped, and Rias took out a bottle of holy water from a subspace, pouring it into her hand.
"No problem."
Not covered by Power of Destruction, yet the holy water, which is like a potent poison to demons, felt like ordinary water to her.
The same was true for Valerie; although not yet awakened, it's merely a matter of not having awakened.
Unconscious transformation, coupled with being a half-breed, Valerie does not possess the weaknesses of ordinary Vampires.
Sunlight, running water, crosses, holy water... one could say Vampires are a race with more flaws than demons.
But as long as one possesses the Sephiroth Graal, everything is easily solved.
The holder of the Sephiroth Graal is too small; forget unleashing its power, she hasn't even awakened yet.
Rias does not want to seize the Holy Grail within her because the connection between a Sacred Gear and its user is too deep; seizing it would be very painful.
Rias cannot do something so cruel, especially to a little girl.
Put another way, if the Gremory family, which values emotions, had a daughter who did such a thing, they would surely be very sad.
Therefore, Rias only needs to copy the power of the Holy Grail.
magical devices and artificial sacred gears have similar characteristics, such as performance being weaker than true Sacred Gears, but their natures are fundamentally different.
magical devices and artificial sacred gears are also weaker than true Sacred Gears, but magical devices contain 'artificial souls,' which ordinary Sacred Gears do not have.
Sacred Gears do not have so-called soul essences, but they possess a more fundamental power.
Rias made the magical devices absorb this fundamental power, thereby obtaining the same power.
If the artificial soul within is strong enough, it can even copy the 'Beast' sealed within the Sacred Gear.
The same kind of magical device is also placed with Gasper, but compared to the Holy Grail split into three, copying it requires more time; generally speaking, Rias doesn't need it anyway.
"The racial flaws of demons have been compensated for. This is truly amazing."
Rias marveled.
The Sephiroth Graal is a Sacred Gear opposite in attribute to Rias; the former governs life, the latter governs destruction.
For Rias, the Sephiroth Graal is a necessary product for her advancement.
Like eliminating the flaws of the demon race, this isn't strictly necessary because, generally speaking, holy light cannot even reach Rias before being destroyed.
But Rias wants to complete the third stage of the Fusion Equation, fusing the essence of life, which requires research into the aspect of 'life.'
The first reason she must obtain the 'Sephiroth Graal' is precisely this.
The second reason is... the Sephiroth Graal involves the essence of life and can help Rias research the method of 'energy transformation.'
Perhaps not research, but obtain the method of 'energy transformation.'
Rias took out a crystal condensed from reishi, guiding a portion of power into the interior of the Holy Grail.
Soon, the Holy Grail began to glow and rotate autonomously.
After a while, Rias sensed a change in the Holy Grail; it had recorded the reishi energy.
Then Rias guided magical power into the Holy Grail's interior. After transformation by the Holy Grail, a strand of reishi energy was born.
"A miracle of life... truly worthy of the Holy Grail."
Even a copy of a copy possesses such power; truly worthy of the Holy Grail recorded in the Bible. That Lord is quite 'omnipotent' indeed~
