Yuki Tsukumo's judgment was correct.
In the end, a Simple Domain is merely an emergency measure.
In the original story, Yuki Tsukumo used her Simple Domain to counter Uraume's Domain Expansion, yet within mere seconds, her Simple Domain was stripped away, and she was directly hit by Uraume's Domain Expansion.
But that was Uraume!
In the original story, Master Tengen personally admitted that Uraume was the only barrier master in a millennium who could be mentioned in the same breath as Kenjaku.
The only one to receive such an honor was Kenjaku.
In this aspect, even Satoru Gojo and Ryomen Sukuna were far inferior to Uraume.
So Kenjaku could strip away Yuki Tsukumo's Simple Domain in seconds, but Yuki Tsukumo should not dream of stripping away Mahito's Simple Domain in seconds!
Mahito laughed loudly.
"It's enough!"
Mahito dragged Kirigiri forward, moving faster and faster!
He felt the vibration of the Cursed Energy core in his spiritual world, as if his very breath vibrated with the core's tremors.
At this moment, his perception expanded to encompass the entire Domain Expansion; not a single ripple in space could escape him.
He had entered the awakened state of Black Flash!
Yuki Tsukumo clearly knew just how troublesome it was once a Jujutsu Sorcerer entered the Black Flash state, let alone when the opponent was the once-in-a-millennium King of Curses!
Her body drifted backward like a ghost, yet Garuda in her hand descended from the sky like a tyrannical blade cleaving heaven and earth.
Kirigiri possessed the world's most powerful cutting ability; even Garuda would be severed the moment they made contact.
But Garuda gave Kirigiri no chance to use its cutting ability.
Enormous mass compression was released with Garuda's swing, the sight akin to a peerless swordsman unleashing a blade aura!
Attracted by the excessive mass, the flying slash continuously drew in surrounding meteorites mid-flight.
The gravitational pull, so strong that even light could scarcely escape, caused the entire flying slash to appear as a profound darkness.
The immense pressure caused the ground to crack open as the flying slash passed, like an abyssal chasm.
While dragging the blade, Mahito suddenly raised his hand.
Kirigiri traced an exceptionally clear arc with his motion—Cutting Line!
Kirigiri collided with the black flying slash.
Mahito could distinctly feel as if he had struck some incredibly hard metallic object.
The increased mass had turned even the air into a solid, unknown substance surpassing diamond.
In the original story, Yuki Tsukumo's Virtual Mass was truly just Virtual Mass; it could only increase offensive power, not defensive power.
But after Domain Expansion, everything changed.
Virtual Mass could cover all phenomena and seemed to impart real mass as well.
An attack carrying the mass of an entire planet was flying towards you—this was the Star Rage Mahito had to face.
Mahito tightly gripped Kirigiri's hilt with both hands and roared.
Kirigiri began to advance with his roar, cleaving through the dark flying slash!
A silver light burst forth from the darkness, and Mahito followed Kirigiri forward.
Yuki Tsukumo stopped her retreat and swung Garuda once more.
The dark flying slash reappeared!
But it wasn't just one.
After the first swing, she immediately swung again without hesitation—three swings!
A torrential downpour of dark flying slashes appeared incessantly, pouring down like a rainstorm, resembling a meteor shower.
Mahito stole a glance at the ground.
The ground of the Domain Expansion: Sumeru Vajra Karma Wheel was composed of countless gravitational ripples.
These ripples shifted with Yuki Tsukumo's movements; they were like the moon orbiting the Earth, constantly revolving around Yuki Tsukumo.
The gravitational ripples were struck by the dark flying slashes, yet no tremendous sound or explosion occurred.
The gravitational ripples, cooperating with the force of the flying slashes, concaved downward.
Even upon directly hitting the ground, the countless gravitational ripples expanded infinitely outward, using the entire barrier to bear the load.
It was utterly silent, bearing any amount of force.
Mahito immediately understood.
This Domain Expansion was specifically reinforced to counteract mass increase.
The internal barrier was almost impervious to destruction from heavy mass impacts, making it incredibly sturdy—likely the most robust Domain Expansion in the world.
Right, only the world's most robust Domain Expansion could withstand the world's strongest stats monster in attack and defense.
Mahito immediately extinguished the idea of deliberately luring Yuki Tsukumo to attack his internal barrier to destroy it.
Now, only two methods remained to defeat Yuki Tsukumo.
First: Seize the right moment, use Kirigiri's Cutting Line to open a breach in this Domain, and escape from within.
This would force Yuki Tsukumo to retract her Domain Expansion.
Based on the phenomenon of Cursed Technique Burnout that inevitably occurs after a Domain Expansion, Yuki Tsukumo would be unable to use Star Rage for a short time.
Seize this opportunity to kill her.
This was difficult.
As mentioned earlier, the gravitational ripples on the ground constantly followed Yuki Tsukumo's movements, indicating she could likely perceive all of Mahito's actions through them.
Now that Yuki Tsukumo had deduced Kirigiri's ability, she would not give him this chance.
Second—
—Confront and kill her head-on!
Before the Simple Domain is stripped away, directly kill Yuki Tsukumo!
Is this really a difficult choice?
Mahito laughed heartily and charged into the meteor shower.
He swung his blade mid-air.
Each massive swing cleaved through a dark flying slash.
He spun in the air, Kirigiri spinning with him, like a storm covering all the flying slashes.
The black meteor shower Yuki Tsukumo unleashed was completely cleaved apart by Mahito's sword storm!
Yuki Tsukumo felt the fervor in her heart slowly igniting.
At this moment, she actually felt a sense of honor.
She found great joy in battling the King of Curses.
This wasn't based on hatred or prejudice, but the pure joy belonging to a warrior.
She certainly knew that for the Lord of Cursed Spirits, the best choice was actually to solidify his defense, then take advantage of her momentary lapse to use the Tsukumogami's ability to cut an opening in the Domain Expansion and escape.
If the King of Curses truly decided to do that, all Yuki Tsukumo could do was rack her brains to stop him.
The battle would shift from overt combat to a covert battle of wits.
That would be the normal progression.
Yuki Tsukumo was also prepared for such a scenario.
But the Lord of Cursed Spirits did not choose that path—he chose a frontal assault!
Just like a warrior charging forward without hesitation, his eyes held no thought of escape or retreat.
In his eyes, there was only a mortal enemy locked in a life-or-death struggle.
Yuki Tsukumo felt, incredibly, the conviction of the King of Curses—so pure and unadulterated.
How could one not feel honor, not feel fervor, when fighting such an opponent?
Yuki Tsukumo only felt her body beginning to heat up.
This was her Cursed Energy, without her conscious control, beginning to flow and circulate at high speed.
Her body had already begun its final warm-up before her own brain could even react.
She let out a high-pitched roar.
"I'm right here, Mahito!"
"Come on, bring it on!"
An overwhelming killing intent fused with force permeated the entire Domain Expansion.
Yuki Tsukumo raised both hands high.
In her palms, Garuda rotated in mid-air.
This serpent-like Cursed Tool Shikigami spun between Yuki Tsukumo's hands in the pattern of an Ouroboros.
An immense oppressive force suddenly contracted.
At the center of Garuda's rotation appeared a black void.
In the original story's life-and-death battle between Yuki Tsukumo and Kenjaku, at the very end, Yuki Tsukumo realized that, having lost the initiative, she could not possibly defeat Kenjaku.
So, she released the limits of her Cursed Technique, hoping to take Kenjaku with her in a self-destructing form.
And in the side notes, it was written thus:
"Within a black hole possessing both ultra-high density and supermassive gravity, not only matter but even light cannot escape."
"It is said that compressing the Earth to a density of about 2 centimeters could produce one."
"Whether gravity, mass, or time, if delved into infinitely—!"
A simulated black hole appeared at the center where Garuda formed its Ouroboros rotation.
