Just as Sukuna was savoring the joy of this increase, an extremely faint yet incredibly sharp 'gaze' pierced through the domain's barrier and landed upon him.
It was the perception of Six Eyes!
Although Sukuna had tried his best to conceal it, the leap in Cursed Energy level was like a bonfire suddenly lit in the darkness. It ultimately failed to completely hide from that man possessing supreme insight.
Tokyo Jujutsu High, edge of the training ground.
Satoru, who was sucking on a lollipop while supervising the sparring match between Yuji and Fushiguro Megumi, paused slightly.
The small round sunglasses on his face slid down his nose, revealing the Six Eyes beneath. His gaze was not focused on the students before him, but pierced through multiple buildings towards a direction in the city—the location where Sukuna's aura had briefly erupted and then rapidly subsided.
"Oh my?" Satoru let out an enigmatic hum, a playful curve appearing on his lips.
"It's only been a few days since we last met, and that old man's stock seems to have increased quite a bit. Quite fast, huh."
He instantly ruled out the possibility of Sukuna having consumed another finger. The fingers under the High School's surveillance showed no anomalies, and Sukuna's current vessel, Utaha, had also been in sight. Thus, there was only one answer—
"It seems that besides Kasumigaoka, our King of Curses has found another incarnation body."
Satoru murmured, but his eyes showed little worry. Instead, they were filled with the curiosity of discovering a new toy,
A bold and crazy thought arose in his mind. He needed confirmation, needed to personally experience just how far Sukuna had reached in this state.
At the same time, this was also an excellent 'teaching demonstration' to let the young Jujutsu Sorcerers beside him personally feel the oppression of top-tier combat strength.
"Hey, Sukuna—" Satoru suddenly raised his voice, the sound seeming to pierce through space and directly resonate in Sukuna's consciousness within the distant domain,
"Looks like your meals have been good lately, your Cursed Energy has increased quite a bit. How about it? Interested in stretching your limbs right here on our High School grounds?"
At these words, Fushiguro Megumi, standing nearby, sharply turned his head, his eyes instantly filling with terror.
"Gojo-sensei! What kind of joke are you making?! Fighting inside Jujutsu High?! Do you intend to flatten the entire school—no, this entire mountain?!"
He could hardly imagine the catastrophic consequences if existences like Satoru and Sukuna fought all out within Jujutsu High.
That was not combat, it was a natural disaster.
Sukuna within the domain, upon hearing this sudden challenge, was first stunned, then an uncontrollable, pure battle ecstasy erupted in his heart like a volcano.
"Hahahaha!!!" His unrestrained laughter echoed in the domain.
"You brat with the Six Eyes, you certainly know how to pick a time. Perfect, I also urgently need a punching bag to test this newly acquired power. As you wish."
Before the words even finished, Sukuna's will, driving Utaha's body, turned into a blur almost imperceptible to the naked eye, rushing towards Satoru at astonishing speed.
Inside the dedicated training barrier of Jujutsu High, the previously peaceful atmosphere vanished, replaced by a suffocating solemnity.
Satoru stood casually in the center of the field, his Six Eyes behind the sunglasses locked onto 'Utaha', controlled by Sukuna, just stepping into the barrier.
Fushiguro Megumi, along with the alerted Yuji, Nobara, and the others, were protected at the edge by a powerful barrier technique, only able to watch nervously.
"Then, let's begin!"
Before Satoru's voice faded, Sukuna's figure had already vanished.
The next instant, he appeared to Satoru's side, delivering a seemingly simple straight punch imbued with terrifying Cursed Energy, enough to blast through steel plates, straight towards Satoru's ribs.
However, when the punch was still a fraction of an inch away from the target, its speed suddenly decelerated, as if sinking into an invisible mire, finally halting in mid-air, unable to advance an inch further—it was Satoru's absolute defense, the neutral form of Limitless, Infinity.
"Hmph, petty tricks." Sukuna scoffed, not dodging or blocking.
The moment Sukuna's fist was blocked, a peculiar Cursed Energy, resembling flowing black water, rapidly spread from the surface of Utaha's body, enveloping her.
This layer of black Cursed Energy was not for attack or defense, but exhibited a neutralizing and permeating characteristic. It acted like a powerful solvent, quietly seeping in and dissolving Infinity.
This was Domain Amplification—an advanced technique achieved by highly compressing one's own domain and enveloping the entire body, thereby neutralizing or even invalidating the effects of the opponent's technique upon contact.
Under the effect of Domain Amplification, Infinity that kept Satoru invincible was temporarily eliminated.
"What?!" A trace of genuine surprise flashed in Satoru's eyes.
In the split second that Infinity was neutralized, Sukuna's counterattack arrived. A fist, carrying the wild power of Sixteen-Finger Cursed Energy, incompatible with this young girl's frame, smashed fiercely into Satoru's palm.
Bang!
A muffled, heavy roar erupted, and a shockwave exploded outward from the two of them, nearly blinding the students standing further away.
Satoru was forced to slide back several meters by the immense force before stabilizing his stance.
Boom! Boom! Boom! Boom! Boom!
Dull, heart-stopping impact sounds exploded within the training barrier, dense like a sudden downpour hitting a tin roof, yet heavy as giant hammers striking bedrock.
The source of the sound was two figures moving at speeds that almost completely exceeded the limits of the naked eye.
One moment, Satoru appeared to be standing casually in place.
The next instant, his figure materialized to Sukuna's left, delivering a sharp hand chop that whistled as it tore through the air toward his neck.
Almost in the same frame, Utaha's body, controlled by Sukuna, arched backward with incredible flexibility and reaction speed, narrowly evading the strike. Simultaneously, his left leg lashed out like a whip, wrapped in maximally compressed Cursed Energy, sweeping at Satoru's lower body.
Boom!
Satoru did not meet the attack head-on. His figure flickered, his true body already appearing behind Sukuna. His fist, enveloped aimed for the back of the neck.
Yet, Sukuna acted as if he had eyes on his back, twisting his body and swinging his arm, his elbow strike covered in Domain Amplification meeting the incoming punch precisely.
The moment fist met elbow, there was no loud explosion, but rather a sound like overburdened glass shattering—a distinct "crack."
The 'Infinity' of Limitless and the 'Neutralization' of Domain Amplification collided fiercely at the microscopic level, canceling each other out and unleashing a distorted force field.
The two separated immediately, sliding backward, but the instant their toes touched the ground—
Bang!
Whoosh!
Satoru's figure vanished again, reappearing mid-air, bringing down a downward kick with the crushing force of a falling meteor.
Sukuna neither dodged nor evaded, driving his right fist upward toward the sky, the black light of Domain Amplification condensing like a drill on his knuckles.
Leg and fist collided, and a visible, ring-shaped shockwave blasted outward, utterly pulverizing the already cracked stone floor beneath them.
Countless fragments of rock were further shattered and vaporized by the residual impact of dozens, even hundreds, of exchanges resulting from the high-speed movement and Cursed Energy clash that followed immediately after.
