"It's over..." Mai's face was as pale as paper, despair drowning her like ice water over her head.
Inside a Special Grade Cursed Spirit's domain, any Cursed Technique's effect would be greatly diminished or even negated unless one possessed a domain of the same level to counter it or could break it with brute force far exceeding the opponent's.
Meanwhile, the caster themselves would receive immense buffs and a sure-hit effect.
They couldn't even move, they could only wait to be ground into dust by this hell of "teeth".
"A death struggle?"
Sukuna's voice remained steady, even carrying a hint of pleasure.
He controlled Utaha's body, standing in the center of this hell of flesh and teeth as if he were at a bizarre art exhibition rather than a lethal killing space.
Those four crimson eyes turned slightly, scanning this horrific cage composed of countless sharp teeth.
"It has some form at least, slightly better than that haphazardly flailing lump of meat from before... just a tiny bit." He critiqued, his tone as flat as if he were reviewing a slightly novel side dish.
"Gurgle... hiss..."
On the domain's "sky" and "ground," those pale giant teeth began to vibrate, grow, and grind frantically, producing a scalp-numbing clattering sound.
The next moment, countless visible gray-white saw-toothed shockwaves, composed of Cursed Energy condensed to the extreme, rained down like a storm from every angle—up, down, left, and right—aiming to shred the only "foreign object" in the domain: Sukuna!
Every saw-toothed impact contained the "sure-hit" rule of the domain, along with the terrifying power to completely chew and digest anything it touched. This was the domain's absolute kill strike.
However, faced with this lethal strike capable of instantly annihilating a Grade 1 Jujutsu Sorcerer, Sukuna simply raised his "hand."
No, it wasn't a defense, nor was it a prelude to an attack. He simply widened those four eyes again.
Hum—
That strange, space-trembling hum rang out again, but clearer and more soul-piercing than before.
In Sukuna's four eyes, the eerie crimson light surged. The brilliant white points at the core of his pupils spun frantically, and the surrounding dark red runes combined, disassembled, and recombined at a speed exceeding the limits of vision.
Kamiutsushi: Full Activation!
In his "vision," the despairing domain, the seemingly flawless attacks, the pervasive "gnawing" rule—its internal structure, the flow nodes of Cursed Energy, the "anchor points" of the rule's power, and even the subtle "inharmonious frequencies" and "structural cracks" that existed because the Cursed Spirit was heavily injured and the domain was on the verge of collapse...
Everything was laid bare under the gaze of those four demonic eyes, as if placed under a high-powered microscope and analyzed frame by frame by the top parsing software.
"Found it." The corners of Sukuna's lips curled into an extremely cold arc.
It wasn't the domain's "strongest point," nor was it the location of the Cursed Spirit's core.
In an instant of billions of calculations and analyses, Kamiutsushi discerned the most fragile and vulnerable "Rule Stress Singularity" of this hastily expanded and imperfect domain—a minuscule logical paradox created during the domain's construction due to the Cursed Spirit's heavy injuries.
It was like a microscopic stress crack on a precision machine caused by forced assembly. Usually harmless, but if struck precisely with the right amount of force at the right time... there was no need to expand one's own domain to counter it.
That would be brute force, a waste.
Before eyes that saw through all rules, a so-called domain was nothing more than a slightly complex model full of loopholes.
Just as the countless gray-white saw-toothed shockwaves were about to drown him, Sukuna moved. Or rather, he controlled Utaha's body to take a light step forward with a seemingly casual yet profoundly mysterious movement.
Simultaneously, he raised his right index finger and lightly tapped the air toward a molar-like protrusion three inches to the upper left that looked no different from the other giant teeth.
There was no world-shaking explosion of Cursed Energy, no flashy or dazzling light from a Cursed Technique.
Only a wisp of extremely condensed, almost imperceptible black Cursed Energy, like the finest needle, shot from his fingertip and accurately entered a sesame-seed-sized dark red Cursed Energy vortex at the tip of that "tooth" that was vibrating at a specific frequency.
That was the domain's "Stress Singularity," the most inconspicuous yet fatal "Redundant Coupling Point" among the hundreds of core flow nodes maintaining the "gnawing" and "enclosure" rules of the entire domain.
Crack.
A sound so faint it was almost inaudible, like the first crack appearing in glass.
The next second—
BOOM!!!
The entire Infinite Maws Hell suddenly stalled. All the saw-toothed shockwaves that were violently closing in froze and solidified less than a centimeter from Sukuna's body, as if they had hit an invisible wall.
Then, centered on the "tooth" that was struck, a massive, distorted black crack, as if space itself were shattering, spread out frantically.
Wherever the crack passed, the writhing flesh membrane, the pale giant teeth, the viscous saliva, the blood-vessel-like patterns...
Everything that composed the domain distorted and fluctuated violently like a reflection in water after a stone is thrown, and then disintegrated inch by inch.
"Im... possi... ble..."
From the depths of the domain came the final hiss of the Cursed Spirit's remaining consciousness, filled with extreme horror and bewilderment.
It couldn't understand why its domain—the final trump card it had bet everything on—would collapse from within like a sandcastle with its foundation removed the moment it was expanded, before its attacks could even touch the opponent.
There was no explosion, no impact.
The collapse of the domain was a breakdown at the level of "rules," an erasure of its very foundation. The dark red hell of flesh and teeth faded and became transparent like a bleached phantom, revealing the dilapidated workshop of the real world behind it.
A massive invisible hand plunged ruthlessly into the core area of the Cursed Spirit's mountain of flesh.
Squelch!
Accompanied by a tooth-aching tearing sound, a massive hand was suddenly pulled out from the collapsing mountain of flesh. Firmly pinched between its fingertips was a withered, twisted, dark-colored finger that radiated heart-palpitating power fluctuations.
It was precisely one of Sukuna's twenty lost fingers.
With the finger removed, the Cursed Spirit's remaining mountain of flesh let out a final, unwilling wail before rapidly melting and evaporating like snow under sunlight, turning into black ash that scattered through the air until it completely vanished.
Sukuna clearly felt the power of Kamiutsushi. The Cursed Energy he consumed to kill this Special Grade Cursed Spirit was negligible. He could have easily killed it using his slashing techniques but still, this was impressive.
