Isekai Adventure in the Dimensional Cube-Chapter 1284 - 928: Domain Expansion

There’s an automatic vending machine here. Gojo Satoru invited Reiger for a fruit juice, while he himself magically produced a suspicious canned drink that seemed alcoholic, sipping it leisurely.

"So, how was it? Did you gain anything worthwhile?"

Once Reiger opened his drink and took a sip, Gojo Satoru cheerfully asked this.

What he was referring to needed no further questioning.

"Not bad." Reiger replied straightforwardly, "The [Red Blood Manipulation] from the Kamoi Family surprised me, Todo Aoi’s [Boogie Woogie] also shows great potential and is worth exploring, and I even saw a girl using [Simple Domain]. That’s quite impressive."

"The one from the New Shadow Style? That’s indeed impressive." Gojo Satoru stroked his chin and said, "But you probably won’t see much use for a simple domain, right? With your abilities, you’d quickly learn even a true domain expansion."

"But at least I haven’t yet, right?" Reiger continued sipping his drink and casually responded, "As for domain expansion, who knows how long it will take me to learn it?"

"I see..." Gojo Satoru took a sip of his drink as well, fell silent for a moment, and suddenly said, "In that case, would you like to see my domain?"

Hearing this, Reiger was taken aback.

Before he could react, Gojo Satoru had already extended his hand and formed a hand sign.

"————"

In that instant, an inexplicable sensation welled up naturally in Reiger’s heart.

Instinct had already warned him that what was coming was extremely dangerous.

"Domain Expansion."

The voice of the strongest Curse Mage of this era echoed between heaven and earth at that moment.

"[Limitless Void]."

In the blink of an eye, the world turned black.

It was a darkness that spread like a tide.

The darkness wasn’t terrifying, nor was it evil; instead, it felt as vast and boundless as the cosmic space.

The space seemed to be infinitely expanding and simultaneously contracting.

Gravity seemed to appear around and then as if completely vanished.

In a place either near or far, a galaxy seemed to sweep across.

Being in such a space, for Reiger, it felt as if even time had lost its meaning, as if he had entered the actual universe, drifting endlessly.

"This is my innate domain."

Without knowing when, Gojo Satoru’s figure appeared behind Reiger, placing a hand on his shoulder, saying so.

"The domain is the spellcaster’s heart-world."

"Domain expansion, in essence, projects the heart-world using cursed energy to construct a field, integrating one’s innate techniques to unfold a barrier."

"Here, the master of the domain is everything; they are the center and the deity of this place."

Gojo Satoru explained with the demeanor of a teacher.

"Everyone’s domain is different because everyone’s heart-world and innate techniques differ."

"Like the juvenile center Curse Spirit you have encountered, after its incubation, the unfolded incomplete domain was its heart-world. As soon as it integrates its innate techniques, it will form a true domain."

"And a true domain, once expanded, grants the spellcaster immense power."

Gojo Satoru raised three fingers.

"First: When the expander of the domain is within the domain, they receive a status boost, similar to a buff in a game."

"Second: When the expander of the domain activates the innate techniques within the domain, the technique will unconditionally hit the opponent—absolute technique hit rate."

"Third: While inside the domain, there is a certain chance that the opponent’s techniques will be neutralized. In other words, no matter how troublesome the spellcaster you encounter, as long as you drag them into your own domain, there’s a way to solve them."

Miwa Kasumi’s [Simple Domain] is a weakened version of such a domain, known as the domain of the weak.

Though simplified, it also retains a part of the domain’s effects, hence Reiger’s [Infinity Techniques] was interfered with by Miwa Kasumi’s [Simple Domain], and the invincible was neutralized, allowing Miwa Kasumi’s attack to penetrate the invincibility and reach Reiger.

Of course, relying solely on the [Simple Domain] to completely conquer [Infinity Techniques] is still too difficult. Miwa Kasumi’s slashing speed was slowed down. If Reiger were serious, she might not have even had the chance to cut Reiger’s finger and would have been dodged directly by Reiger.

Had Miwa Kasumi expanded an actual domain at that time, it would have been a different story.

Anyone capable of expanding a domain can hit an [Infinity Techniques] user.

Thus, the best way to deal with [Infinity Techniques] is domain expansion.

However, domain expansion represents the pinnacle of curse battles, the ultimate of curses, not something everyone can learn.

Curse Mages who understand domain expansion are at least grade one Curse Mages, and among grade one, nearly ninety percent of people don’t know domain expansion. Below grade one, it is unnecessary to mention; anyone who learns it will be immediately recommended as a grade one Curse Mage.

If two of the same grade fight, and one can expand a domain, that person basically wins unconditionally.

Additionally—

"Each spellcaster’s domain generates different power based on different innate techniques."

"For example, take me. After domain expansion, I pull opponents into the inner side of infinity, forcing their brain to repeat countless ’perceptions’ and ’transmissions’ for survival, generating a lot of useless information, causing the brain to lose functionality, leaving them to stand there awaiting death. Only I and whom I touch can remain unaffected."

"This is my domain—[Limitless Void]."

As this statement ended, in the next second, the whole cosmic space began to shrink, gradually vanishing.

Reiger and Gojo Satoru returned to the atrium, to the side of the automatic vending machine, as if nothing had just happened.

But Gojo Satoru’s hand was still on Reiger’s shoulder, proving that everything just now was no illusion.

"How was it? With your learning capability, you should be able to grasp the principles of domain expansion at a mere glance." Gojo Satoru patted Reiger on the shoulder, saying, "As another user of [Infinity Techniques], if you learn domain expansion, you might acquire the same [Limitless Void] as I have?"

"But who knows, whether your domain and mine are the same."

The domain involves barrier techniques, as well as the spellcaster’s heart-world.

If Reiger constructs his innate domain using cursed energy, there’s a strong possibility of expanding a domain entirely different from Gojo Satoru’s.

But if the innate techniques applied within the domain are the same, even with different views of the world, Reiger might eventually acquire the power of the [Limitless Void] domain.

In other words, if Reiger applies [Infinity Techniques] to his expanded innate domain, he might get the same effect of causing the enemy’s brain to dysfunction, making them stand idle to die.

And if Reiger applies an innate technique other than [Infinity Techniques] within the innate domain, it will result in a different domain.

"I think if you learn domain expansion, you will become very terrifying."

Gojo Satoru remarked as if in admiration.

"Yuta can also mimic other people’s techniques, but this ’mimicry of others’ techniques’ is his technique itself, so the domain he expands will only apply this technique, gaining power related to it."

"But you are different; the techniques you learn become as if they are your own. You can fully choose according to the situation, freely applying different techniques within the domain to gain different domains."

"With this capability, you may become the first Curse Mage in the world of sorcery to possess multiple domains."

"By then, you would become more powerful than me."

Just as Gojo Satoru was speaking these words endlessly, Reiger suddenly spoke.

"Are you anxious?"

The single question left Gojo Satoru speechless.
