Chapter 439: Pseudo-Simulated Universe Chart: Mystery Foundation

"The Golden Alchemy," also known as "Ars Magna."

In the common understanding of alchemy, "Ars Magna" is often seen as the process of turning base materials into gold. That is the fundamental pursuit of alchemy, as gold symbolizes wealth, and wealth can solve 99% of problems.

However, the Ars Magna that Li Mo possesses is not a technique for refining gold. It is a terrifying grand magic. If completed, this grand magic would allow him to convert all things in the world into incantations within a certain domain, including gods and demons—essentially, "everything in the world" could be manipulated at will.

In the worldview of A Certain Magical Index, gods are nothing more than beings existing within phases. Having witnessed the angels of that world, Li Mo had no respect for such phase-based deities.

Understanding that world, all attention would naturally turn to the Magic Gods. But Magic Gods and humans are not the same kind of beings. Magic Gods who abandon their obsessions are, to some extent, soulless husks. Yet, there are also monsters like Aleister Crowley.

A man who could have become a Magic God but chose not to.

In the context of the Type-Moon universe, Aleister Crowley would be someone who reached the Root and then scorned it—a true monster.

Li Mo had obtained two techniques from that monster: "Spiritual Tripping" and "Blasting Rod." On the surface, these techniques seemed simple, but no matter how hard he tried, he couldn't master them. They were far more complex than his "Divine Manifestation: Raiden Shogun."

This is why Li Mo turned his attention to the Ars Magna.

The battle between Raiden Ei and the Raiden Shogun erupted. The clash of the Musou Isshin and the Engetsu Isshin rang out, clear and melodious.

The collision of "Transience" and "Eternity."

Raiden Ei had never confided her thoughts to her friends. But from her actions, it was clear that she had ultimately chosen the same path as Makoto. In the end, wasn't it Raiden Ei who had changed, while the Raiden Shogun remained the same?

The Shogun symbolized the "Ei" of the past.

Li Mo retreated to a corner, setting up a barrier. He was preparing to begin a chant that would last for centuries.

Learning and casting the Ars Magna wasn't particularly difficult. It was much simpler than techniques like "Blasting Rod" or "Spiritual Tripping." The trouble with this alchemy lay in the centuries-long chant, which could not be interrupted.

For ordinary people, an individual could not withstand the torment of centuries. If it were a family passing down the chant through generations, the differences between individuals would make it difficult to ensure the chant was performed flawlessly.

Those who needed the Ars Magna often lacked the talent to complete it, while those who had the ability often disdained such grand magic.

Li Mo needed this grand magic. Its potential was immense.

He wanted to transform his body into an independent vessel for accumulating mystery. This was similar to a Magic Crest, but it still needed to resonate with a foundation to be used. Even from the perspective of magic in the "A Certain Magical Index" world, magic required human thought and belief to function.

A thought or belief known to many could be used. However, something known only to one person could not. This was why techniques like "Thororm's Spell" and "Light of Judgment" failed. But techniques that strengthened the body internally could still be used.

—The interior of the human body was more conducive to accumulating mystery. It wouldn't affect the outside world, nor would it generate backlash from altering the external environment.

In a sense, in the concept of mystery, the human body was a small world. Using the Ars Magna, Li Mo could solidify the concept of this "small world," creating a worldview unique to himself. Even in a world like Teyvat, which lacked Earth's culture, he could still establish the necessary ideological framework.

As for how to use the Ars Magna to create a worldview unique to himself, Li Mo already had a model in mind: the "Simulated Universe Chart," which existed in the same universe as the "Shadow of the Dragon."

The "Simulated Universe Chart," also known as the "Blueprint of Another Universe" or "The Divine Blueprint for Creating a Universe," was a powerful blessing that projected one's own universe onto the external world, interfering with reality.

Of course, something of that level couldn't be replicated with the Ars Magna. What Li Mo borrowed was merely the prerequisite ability.

The "Simulated Universe Chart" was the ability to project one's own "universe" onto the external world. The prerequisite was to possess a "universe." What Li Mo replicated with the Ars Magna was precisely this.

The Ars Magna allowed one to replicate what they believed in within a certain domain. If something couldn't be believed, it couldn't be replicated. Conversely, if you didn't believe in something, you couldn't manifest it.

In the world of *A Certain Magical Index*, a alchemist named Aureolus Izzard completed the Ars Magna, becoming nearly invincible within his domain. Yet, he ultimately failed due to his own wavering beliefs.

By limiting the Ars Magna to the interior of his body, Li Mo could minimize the influence of external ideologies. He then fixed the magic's purpose to "solidify mystery." Once the Ars Magna was completed, the process would begin to operate. The **Spiritual Foundation** within his body would become the mystery from another world!

The goal of solidifying mystery was to use techniques that couldn't be employed in other worlds. Using techniques from other worlds would further reinforce his belief in "solidifying mystery." This cycle would continue, solidifying his thoughts, and the drawbacks of the Ars Magna would not manifest.

Once the mystery was solidified within his body, how could he then influence the external world?

Li Mo's choice was... "Personal Reality".

The development of **esper abilities** in Academy City gave him the perfect inspiration. The essence of it was to damage and distort the human brain to a certain extent, creating a **Personal Reality** unique to oneself, and then projecting that distortion onto reality, thereby altering it.

Li Mo borrowed the latter half of this concept—using the distortion of **Personal Reality** to twist reality.

He was no genius and couldn't independently create his own techniques from scratch. But his strength lay in absorbing and piecing together the concepts of others' techniques.

Using the **Ars Magna** as the technical foundation, the **"Simulated Universe Chart"** and **"Personal Reality Development"** as the conceptual framework, and supplementing it with other techniques, Li Mo created a grand magecraft—

"Pseudo-Simulated Universe Chart: Mystery Foundation"!

The incantation began, its tone and rhythm nearly perfect.

What followed was centuries of perseverance. To prevent any mishaps that could ruin everything, Li Mo brought himself to his peak condition. The nine-tailed celestial fox revealed its full form.

And so, time flowed relentlessly onward.
