After the research on Soulfire came to an end, Ian did not stop exploring. According to the records left by the future version of himself, there are two core solutions for the construction of "Magic Domain".
In order to verify the practical value of these theories, Ian entered a room of Chamber of Secrets that was blessed with high-level defensive techniques to ensure that the destructive force erupted during the test would not spread to the outside world.
Ian decided to start with the first option. He put aside his reserve as Empire Overlord, followed the enthusiasm for extraordinary power deep in his heart, formed a mysterious mark with his hands, and chanted in a low voice. "Domain Expansion: Wizarding World."
In an instant, the surrounding space was violently shaken and reorganized. Ian found himself in an independent space that seemed to be nothing. However, under the originally empty shell, it was filled with extremely rich magic power.
What amazed him even more was that every trace of magic in this space was deeply imprinted on his soul, which meant that he had absolute control here.
In order to test the amplification effect of the field, Ian cast a basic elemental spell - Fireball. With the terrifying magic density in the field, the power of this fireball was at least 20% higher than that of the outside world.
However, after the initial excitement, Ian's keen insight quickly calmed him down. "There are too many flaws in the plan in this field." He frowned and analyzed.
In essence, this technique is just an extreme variant of Sealing Magic. The caster constructs a closed space through Sealing Arts, then spreads his own magic into it and imprints it with Soul Imprint. Although extremely high concentrations of magic can greatly amplify spells and can repel any other form of energy, its underlying logic is not stable.
The first fatal weakness is the consumption of magic power. In order to maintain the stability of the sealed space and fill it with magic power, Arcanist must overdraw a massive amount of its own reserves, which will cause the remaining magic power in the caster's body to become extremely dangerous after Domain Expansion.
Although the excellent Arcanist can make up for this by manipulating the magic in the environment, this is ultimately a huge hidden danger.
The deeper problem is that this kind of field based on Sealing Arts is "too easy to be destroyed." The ultimate goal of building a field of Ian is to confront the "Divine Kingdom" of the gods head-on.
According to the data collected so far, the gods are almost omniscient and omnipotent in their own kingdom. If a ninth-level god can cut off the opponent's induction, he can even seal the tenth-level existence in that small area. If the god chooses to hide in the kingdom of God, the difficulty of hunting will increase exponentially.
Currently, Empire's only means of fighting against the Divine Kingdom is to use Floating City for external bombing, but this has not been tested in actual combat. Ian is worried that Divine Kingdom Projection may interfere with the core functions of Floating City.
He urgently needs a "Magic Domain" that can directly invade and disintegrate Divine Kingdom at the dimensional level. He even had a crazy idea: to kill the Bleach spirit within the Divine Kingdom and completely crush the arrogance of those gods.
In addition, in the future, Ian tried to imitate the logic of <Jujutsu Kaisen> and replaced "Innate Curse Technique" in the spell system with an arcane model. However, in actual operations, it was found that Arcanist is known for its variability, and solidifying a single spell into a field limits the upper limit of combat.
Even if future versions enchant the sealed space as an alchemical product, it can only carry up to 7 spells, which is far from meeting Ian's requirements for universal combat.
Therefore, this plan was eventually eliminated from the official version by Ian in the future, and was only used as a reference plan for wizards or contractors who specialize in a few powerful spells.
"Master, don't you feel embarrassed at all about the middle-level seal gesture just now?" Morgana jumped out and turned on the poisonous tongue mode without mercy. Ian responded calmly without changing his expression, "As an emperor who is committed to building a huge harem, 'shamelessness' is one of the basic qualities that are necessary." "Okay, I'm embarrassed for you." Morgana turned over Byakugan.
Ian ignored the artificial intelligence's ridicule and began to test the second and more promising method. He looked solemn, clasped his hands together and shouted, "Domain Expansion: Truth Manifestation."
The space changes again. This time, Ian is not in nothingness, but sitting on a majestic golden throne, with a majestic gate towering into the clouds behind him.
The giant door is engraved with ancient religious totems that symbolize Truth and knowledge, such as a single eye, a triangle, and a lotus. At the foot of the throne is a bookshelf that extends to the end of the line of sight. Massive books are suspended in the air or scattered on the ground. The entire space is filled with an almost substantial arcane brilliance.
"Exquisite." Ian praised. The core breakthrough of this plan lies in "Soul Dimension Projection". In the future, Ian will solve the problem of how to directly map Arcanist, the origin of the runes - Soul Dimension, to the real world.
In this mode, the domain will evolve into a specific form based on the nature of the caster. As the lord of the Empire and obsessed with knowledge, Ian presents the vision of the throne, Gate of Truth and endless the Library. When he cast Fireball again, a certain page in the sky flipped, and the power of the spell instantly increased by at least 40%.
Ian calmly analyzed the source of this increase in Sea of Consciousness. This bonus is not just from the resonance of magic power, but also from the direct mobilization of the cluster of "Soulfire" deep in the soul. He asserted that once he can completely control Soulfire in the fourth dimension, this increase will usher in a qualitative leap.
However, Morgana's words once again poured cold water on it: "The idea is great, but its popularity is worse than the first one." "Indeed," Ian said with a bitter smile.
According to future research data, the pure Soul Dimension Projection is actually a layer of phantom that cannot interfere with reality. If you want it to produce physical-level lethality, it must be combined with a real "Subspace" that can be generated instantly to create a high-dimensional Fusion.
This is the core bottleneck: the caster must have the ability to "instantly open up Subspace". And in today's huge Arcane Empire, apart from Ian himself, there are actually less than 50 space system Arcanist people who can do this.
Space Magic is inherently obscure and difficult to understand, let alone achieve this level of attainment. Even if preparation time is given to open up space in advance, its extremely high threshold destined that this technology cannot be promoted in the mass army.
"At least, we have seen the direction of progress clearly." Morgana concluded. "That's right." Ian nodded in approval.
The next key point in realizing the "complete body Domain Expansion" is to find a method that can directly allow Soul Dimension to interfere with reality without the need for a physical medium (such as Subspace).
Just like the Divine Kingdom of those ancient gods, the domain itself is the embodiment of the will without the need for a carrier to be Truth. In the magic Warpath leading to the legendary peak, this level called "Domain" has been opened by Ian himself, a gap full of hope.
