Chapter 239 The World of Death and the Third Law
Seireitei, deep within the barracks of the 12th Division.

This is the core of the Technology Development Bureau, the most heavily guarded and mysterious forbidden area in the entire Soul Society.

The air was filled with the pungent smell of disinfectant mixed with some unknown chemical reagent. On the cold metal walls, countless pipes of varying thicknesses twisted and extended like the blood vessels of a monster, eventually converging into huge culture tanks that shimmered with an eerie green light.

In the center of this realm filled with non-human objects, Mayuri Kurotsuchi sat quietly on his throne, lost in thought.

He was contemplating the information provided by someone from another world…

"I see... I see... Indeed, my world is the most suitable place to study this kind of thing..."

Laughter echoed in the empty laboratory, carrying a chilling frenzy and excitement.

[Report on the Holy Grail War], [Analysis of the Third Magic: The Heaven's Cup], [Sample Data of Angra Mainyu], [Data from the Einzbern Artificial Workshop]...

"The materialization of the soul..."

Mayuri Kurotsuchi murmured, "In Kenneth's world, the soul is an ethereal, unobservable, and uninterrupted entity."

Even in a world where ninjas roamed freely and could use the "Impure World Reincarnation" technique to briefly recall the dead, its essence was nothing more than using chakra as a medium to forcibly "record" the deceased's information onto the body of a sacrifice.

In the world of one person, although cultivators can cultivate so-called "Yin God" and "Yang God" to give their spiritual bodies the power to interfere with reality, the threshold is too high. It requires a lifetime of arduous cultivation and is a privilege reserved for a very few geniuses like Zhang Zhiwei.

But his world... Soul Society, is completely different.

In this world, the existence of the soul is taken for granted.

Even an ordinary person who is unarmed in the real world can naturally transform into a complete spiritual body after death—"the whole"—retaining all their memories and personality from their previous life.

However, if this soul falls into depravity due to obsession and becomes "empty", its existence can even erode the material world, devour living beings, and cause enormous destruction.

The root of all these phenomena lies in the fundamental particles that constitute Soul Society, Hueco Mundo, and even the soul itself—spirit particles.

It is both energy and matter; it can construct the spirit and also interfere with reality.

Isn't this the "Third Magic" of the Type-Moon world, an imagination that uses the mind to interfere with reality?
"It's really amazing..."

Mayuri Kurotsuchi sighed again, acknowledging that this was an advantage unique to him.

Different world environments lead to different technological directions.

Because the essence of science is the summarization of the laws of the objective world, just like coastal civilizations are bound to be more developed in shipbuilding than inland civilizations.

"Einzbern's artificial human technology..."

His gaze fell upon the detailed information about androids.

From the first "Winter Saintess" Justeza to the subsequent mass-produced Irisviel series, the core technological concept is to create a body that can perfectly simulate the physical structure of a "Third Magician".

No, it should be said that the field that the Einzbern family spent a thousand years and took countless detours to barely reach was a technology that his world had already developed for many years.

However, it does have some rather unique aspects...

The "Gi-Ton" in Soul Society is nothing more than a specific personality program implanted into a blank soul; in essence, it is still a modification based on an existing soul.

What his predecessor sought was to create something from nothing, using spiritual particles as raw materials, like a god, a completely new, complete soul with self-awareness!

His most prized creation, Neonmu, is the pinnacle of this research.

She is a perfect combination of "artificial soul" and "artificial body" technologies, a "man-made death god" created and tuned entirely by human hands.

Even Nemuro has an innate defect.

Her soul, ultimately, was born within a pre-set framework, lacking something fundamental.

Now, the Einzbern family's technology has opened a completely new door for him.

This technology was born in a world where the soul is difficult to access, in order to materialize the soul. In this world where the soul can easily interfere with reality through spiritual particles.

What kind of miracle will be born from the combination of these two?
"Come on, come on! Let me see what kind of things can be born in a world full of 'spiritual particles', guided by the true theory of 'soul materialization'!!"

Thinking of this, Mayuri Kurotsuchi could no longer suppress his excitement and fervor.

He suddenly stood up from the throne, the hem of his wide shihaka robe fluttering even without wind.

He turned and strode towards the deepest part of the laboratory.

That place was his most private research institute, a forbidden area whose existence was known only to a very few people even within the Technology Development Bureau.

The heavy metal gate slowly opened amidst the complex grinding of gears, revealing an even larger and colder pure white space.

In the center of the space, a huge cylindrical petri dish stood quietly, filled with a pale green culture medium.

Countless fine silver lines, like a neural network, are spread throughout the inner wall of the container, maintaining the absolute stability of the internal environment.

This is the birthplace of Nemu Kurotsuchi, the vice adjutant of the 12th Division.

Mayuri Kurotsuchi walked to the control panel, his slender fingers dancing rapidly across the cold metal keyboard, producing a series of crisp tapping sounds.

Without the slightest hesitation, he directly retrieved the original data from when he created Nie Yinmeng.

Then, based on that, modifications are made by inputting the complete physical parameters of "Irisviel von Einzbern," the top secret of the Einzbern family from another world.

"Based on the 'Winter Saintess'... a magic circuit specially designed to carry and activate the Third Law..."

"Hmph, in my world, this should be called a 'spiritual circuit'."

As he entered the data, he muttered to himself in his unique, sharp-tongued voice.

"Then... let the experiment begin!"

With his command, Mayuri Kurotsuchi pressed the final start button.

Om-!
A low rumble emanated from the entire underground laboratory.

Inside the enormous petri dish, the pale green culture medium began to surge and swirl violently, forming a deep vortex. Simultaneously, the pipes lining the walls lit up, and a massive flow of spiritual particles, like a burst dam, was frantically drawn in, compressed, and poured into the center of the petri dish.

High concentrations of spiritual particles began to gather at the center of the vortex. At first, it was just a blurry point of light, but soon it rapidly expanded and solidified.

Flesh and blood began to grow.

It wasn't a gradual growth process, but rather a kind of construction that was almost like "printing".

Using spirit particles as ink and the genes of the Einzbern family as a blueprint.

A flawless white skeleton appeared out of thin air, like a finely crafted ivory work of art. Then, pale pink muscle fibers rapidly coiled around it like vines, weaving a perfect body curve. Delicate and fragile blood vessels and a nervous system, like a red and blue spiderweb, precisely spread to every corner of the body.

Finally, a layer of delicate, sickly pale skin enveloped everything.

The long, silver hair slowly unfurled in the culture medium, like seaweed swaying in the deep sea.

In just a few minutes, the body of a young girl was perfectly "created".

She floated quietly in the culture medium, her eyes closed, her expression serene, like a sleeping angel.

But at the very moment the girl's body took shape, a strange change occurred!
boom! ! ! ! ! !

An indescribable, terrifying spiritual pressure erupted from the slender girl's body like a volcano bursting its banks!
What followed was a massive explosion...
