Isekai Adventure in the Dimensional Cube-Chapter 1241 - 904: Black Flash

The next day, the students and teachers of the Jujutsu High, along with the sorcerers, were shocked to find that the school buildings, damaged just a few days ago, had returned to normal overnight.

It wasn’t just the school buildings; even the forests outside the city were fully restored overnight. The scenes of devastation as if struck by a natural disaster had completely disappeared.

This caused quite a stir among the sorcerers and left Gojo Satoru and Yaga Masamichi astonished.

"It really got fixed overnight?"

Gojo Satoru’s expression was one of disbelief.

"......"

Yaga Masamichi said nothing, just furrowed his brows, lost in thought.

While everyone at the Jujutsu High was amazed by the overnight restoration of the school and the forest, Reiger had already returned to the clearing in the forest.

He wasn’t developing the "Limitless Curse Technique" and "Ten Shadow Techniques" like before. Instead, he stood in front of a rock, gazing at it thoughtfully.

After a long pause, a surge of curse energy suddenly emerged from Reiger’s body.

The curse energy flowed like "Flowing Flames," rushing toward one of Reiger’s hands, where he gathered it.

Then, Reiger raised the hand full of curse energy and slowly clenched it into a fist.

A second later, the curse energy gathered in Reiger’s hand suddenly transformed, bursting out like black lightning.

"Boom!"

Reiger slammed his fist imbued with black lightning heavily onto the rock in front of him, unleashing a formidable force that shattered the rock.

A giant rock as tall as a person was smashed so easily; if ordinary people saw it, they’d certainly be amazed, right?

Of course, for sorcerers with curse energy, it’s not too difficult.

For instance, if Itadori Yuji mastered curse energy, he should be able to do the same.

But essentially, what Reiger did was much more complicated than simply enhancing his fist with curse energy and then striking.

After delivering this strike, Reiger immediately felt the astounding changes in the curse energy flowing within him.

More accurately, the flow of curse energy was now much smoother and easier than before, flowing naturally and calmly, as if entering a state of original simplicity, touching a realm that’s hard for others to reach, very mysterious.

"Is this the Black Flash?"

Feeling the curse energy in his body flowing much more smoothly and naturally than before, Reiger showed a thoughtful expression again.

—The Black Flash.

This isn’t a curse technique but an art passed down among sorcerers.

When sorcerers strike and use curse energy to enhance the power of the blow, if the discrepancy between the strike and the impact of curse energy is within 0.000001 seconds, a unique spatial distortion phenomenon occurs.

This is a phenomenon that only appears with sorcerers, a natural change of curse energy.

Once this phenomenon occurs, the power of the sorcerer’s attack is increased to 2.5 times the usual.

Yes, not 2.5 times, but to the power of 2.5.

This means that just by this fact alone, a sorcerer’s strike can go from a normal attack to a deadly blow.

This is the technique that Reiger calls the Black Flash.

"I thought it would be much harder, but it’s just like this."

Reiger smiled and said something that other sorcerers would surely collectively roll their eyes at if they heard.

A discrepancy between the strike and curse energy impact within 0.000001 seconds?

Is this a discrepancy humans could easily control?

Such minuscule discrepancies are almost beyond human control.

In other words, within the world of sorcery, no sorcerer can purposely deploy the Black Flash like Reiger.

Those who have used the Black Flash either succeeded by chance or were in a heightened battle state, with adrenaline surging and senses and instincts enhanced, allowing them to succeed after several attempts.

As for Reiger, who succeeds at it with a casual try?

Unfortunately, there is absolutely none in the world of sorcery.

Even Gojo Satoru couldn’t achieve it.

The reasons Reiger succeeded so easily are mainly due to three factors.

Firstly, his curse energy manipulation skill has reached a level comparable to those with the Six Eyes, allowing him to smoothly channel curse energy within tiny time discrepancies.

Secondly, the development ability "High-Speed Combat" enhances his nerve reflexes and reaction to inhuman levels, allowing him to quickly adjust curse energy to keep up with the strike speed even within such minuscule time.

Thirdly, the existence of the Transparency World allows him to fully grasp his muscle movements. The enhanced senses also allow him to effectively control the force of his strike without losing control of the flowing curse energy.

With these three factors combined, the Black Flash, a technique nobody else in the world of sorcery could deliberately use, can now be casually employed by him.

"If Gojo and Fushiguro were still here, they’d probably think I’ve made another historical achievement, right?"

Reiger’s eyes flickered slightly.

"As described in the original work, the distance between those who have experienced using [Black Flash] and those who haven’t, to the core of curse energy, can be said to be worlds apart."

Once [Black Flash] is successfully unleashed even once, the Curse Mages will enter a strange state or realm, much like Reiger at this moment.

In this state, they are much closer to the core of sorcery, and the flow of their curse energy undergoes a fundamental change.

In a nutshell, it is being able to more deeply understand the essence of curse energy, to more clearly perceive the true meaning of sorcery.

This will greatly influence the power and potential of a Curse Mage, having a significant promoting effect on their growth.

Just like Reiger at this moment, he had a feeling that if he were to use [Limitless Sorcery] and [Ten Shadow Techniques] now, the power of these two techniques would change significantly, and even the difficulty in controlling them would undergo a fundamental change.

Therefore, Reiger was pondering the technique of [Black Flash] here, trying to successfully use it.

However... the thing Reiger wanted to attempt was not just this move, [Black Flash].

"Space distortion occurring when the disparity between strike and curse energy impact is within 0.000001 seconds?"

"So, the reason this move’s power increases so much is not due to the disparity between strike and curse energy, but because of this phenomenon of space distortion?"

"A phenomenon of curse energy that can cause spatial distortion... could it be possible to incorporate this move into my swordsmanship?"

Reiger was considering such matters.

Or rather, he was thinking about [Dimensional Slash].

This was originally an ultra-tier final skill used by players of a profession called "World Champion" in "YGGDRASIL," capable of cutting space.

Even [Present Break], a tenth-tier magic, is just a degraded version of this skill, and Reiger could only attach [Present Break] to his sword in the state of activating [Lost Revelation], enabling the use of this skill.

Such use of [Dimensional Slash] is more of a magic than a skill.

Without using [Present Break], this move cannot be executed.

Without activating [Lost Revelation], this move cannot be executed either.

And [Lost Revelation] is a magic with a time limit, which would be too troublesome if executing [Dimensional Slash] every time requires the consecutive activation of two magic assists.

But if one relies solely on technique to accomplish something like "cutting space," even Reiger felt that it was a bit demanding.

At least, Reiger had not yet succeeded in accomplishing this.

This shows that relying solely on technique to cut space is something that happens only in mythical stories and fantasy novels.

But now, Reiger felt that he might have found a solution.

"If I can integrate [Black Flash] into my use of swords, then even slashes could trigger the phenomenon of space distortion."

"And if I can further use curse energy to control this distortion phenomenon, converting impact into slashing, won’t the distortion phenomenon turn into a cutting phenomenon?"

"Space cutting... isn’t that [Dimensional Slash]?"

This is what Reiger wanted to try.

If he could truly accomplish it, not only would the idea of [Dimensional Slash] long envisioned be fulfilled, but [Dimensional Slash] would also possess power similar to that of [Black Flash]?

Cutting phenomena... aren’t they more destructive than distortion phenomena?

By then, the increase in power shouldn’t just be 2.5 times, right?

"Sure enough, curse energy and sorcery can be integrated into close combat systems."

"The fact that Curse Mages in this world generally engage in hand-to-hand combat proves this point."

"Highly offensive curse energy and sorcery might not match magic in terms of functionality, but they certainly exceed it in power."

After mastering both [Limitless Sorcery] and [Ten Shadow Techniques], Reiger also felt that the plasticity and flexibility of sorcery exceeded that of magic.

Take [Limitless Sorcery] for example, it has both the positive and reverse manipulations of techniques, and even advanced uses beyond that, plus numerous derived uses that, once fully developed, can yield amazing effects in various ways.

[Ten Shadow Techniques] is the same, with its fundamental effect being the summoning of shikigami. But the different ways of using shikigami bring about various changes in combat.

In contrast, magic’s effects are all fixed.

[Fireball] gathers a mass of flame and shoots it out to attack enemies.

[Thunder Strike] gathers and shoots out lightning.

The influence a magician can exert on them is injecting magic power to change their power or range of effect.

But with sorcery, even if you fire off a fireball, you can change its quantity, direction, or scatter during its course, employing it in various ways.

That’s precisely why Reiger was interested in the system of curse energy and sorcery.

"Once an idea germinates, it must be tested."

With a direction in mind, Reiger immediately took out the Hermit from the dimensional cube’s storage space.

Before long, black lightning appeared frequently here, letting curse energy permeate the area.
