Crimson Blood Manipulation Technique grants a burst of power far exceeding that of ordinary people, and the blessing of Hymn of Prayer pushes the punch speed beyond its limits.
Rin's right fist, wrapped in black and red chaotic Cursed Energy, struck fiercely at the Lightning Cursed Spirit's face with a sharp, air-tearing sound.
However, this time, the Cursed Spirit abandoned all defensive postures.
Just before the punch reached him, his pale body transformed into a crackling mass of blue electricity, vanishing from Rin's sight as if melting into the air.
"Hmph."
Rin snorted, his Crimson Sharingan already having caught the trajectory of the surging electricity.
The moment the Cursed Spirit's form reassembled behind him, he twisted his waist sharply, his left arm sweeping out like a steel whip, a hook punch cutting through the air straight for the opponent's vital spot.
But the punch still found nothing.
The mass of electricity instantly teleported again, appearing beside Rin in the blink of an eye, and the Cursed Spirit's reassembled fist, wrapped in dazzling electric light, solidly struck his cheek.
"Bang!"
A dull thud sounded, and Rin's body flew backward like a kite with a broken string, his black hair swept up by the airflow, a stinging sensation of electrical burn lingering on his face.
But he quickly adjusted his posture in mid-air, and the surging Cursed Energy around him formed an invisible barrier, forcefully deflecting most of the impact, stopping only a few meters after landing steadily on the ground.
The lightning effect on the Cursed Spirit's fist had already been nullified by the defensive layer formed by the Hymn of Prayer, causing no substantial damage.
Rin raised a hand to wipe a trace of blood from the corner of his mouth, looking at the Cursed Spirit opposite him, his eyes not grave, but instead burning with intense interest.
This Cursed Spirit's formidable strength was far more than just surface-level speed.
He could completely transform himself into electricity, achieving displacement similar to spatial flickering; this application of Cursed Technique was truly bizarre.
Rin knew very well that even if he copied this Cursed Technique with his Sharingan, he would never be able to use it like his opponent.
The fundamental reason lay in the completely different forms of existence between the two.
Cursed Spirits are composed of pure Cursed Energy; as long as their core is intact, no matter how their body decomposes and reassembles, they can recover as before.
But he was a human being of flesh and blood; if he forcibly converted his body into electricity, he would likely be torn apart by the powerful energy instantly, perishing before he could even use Reverse Cursed Technique.
This was the unique advantage of Cursed Spirits.
Although they cannot master Reverse Cursed Technique to heal themselves, they can push the power and applicability of their own Cursed Techniques to the extreme.
Just like Choso's Crimson Blood Manipulation Technique, when humans use it, they are limited by the total amount of blood in their body, and without understanding Reverse Cursed Technique, they could easily risk their lives due to excessive blood loss if they are not careful.
But Choso can simulate blood with Cursed Energy, naturally allowing him to expend it without restraint, maximizing the destructive power of Crimson Blood Manipulation Technique.
The Lightning Cursed Spirit before him was also like this; the transformation into an electrical form gave him an absolute mobility advantage in close combat.
Rin stretched his neck, his bones making a crisp sound, and black and red Cursed Energy once again gathered around him, the tomoe in his Sharingan spinning rapidly.
"How interesting."
A cold smile played on his lips.
The Cursed Spirit also noticed the white light surrounding Rin; his lightning-covered fist, which should have severely injured Rin, was now unable to cause any substantial damage.
The Cursed Spirit clearly had a backup plan.
The moment Rin mobilized his dark Cursed Technique to interfere with the trajectory, he once again transformed into a dazzling lightning bolt, ignoring the obstruction of the aura, and instantly appeared beside Rin.
His pale fist, wrapped in crackling electricity, struck fiercely at Rin's arm with enough force to shatter rock.
"Still the same old trick."
A sharp glint flashed in Rin's eyes; his Sharingan precisely captured the trajectory of the converging electricity.
He did not dodge, slightly raising his left arm, and the Hymn of Prayer around him instantly surged, pure white Cursed Energy forming a dense defensive layer, solidly blocking the outside of his arm.
Based on past experience, this would be enough to nullify the Cursed Spirit's lightning attack.
But just as the fist touched the defensive layer, a strange smile suddenly appeared on the Cursed Spirit's pale face.
An alarm blared in Rin's mind, and the next second, a sharp pain shot through his arm, as if an invisible sharp blade had directly penetrated the defensive layer and savagely cut into his flesh.
"Not good!"
Rin reacted extremely quickly, immediately turning sideways and retreating rapidly, putting several meters of distance between himself and the Cursed Spirit.
He looked down at his arm, only to see a deep wound, visible to the bone, from which blood continuously gushed; the pure white Hymn of Prayer Cursed Energy flickered at the edge of the wound, but it had failed to block this sudden attack.
"Sure-hit effect?!"
Rin's pupils contracted sharply; he instantly understood the crucial point.
It wasn't that the Hymn of Prayer had failed, but that the Cursed Spirit's attack had an added sure-hit property, which could only be achieved within a Domain, and it was without opening a Domain!
This completely overturned his understanding of Cursed Techniques.
One must know that even a thousand years ago, very few people could directly integrate a sure-hit effect into a single attack without relying on a Domain.
The intricacy and power of this Cursed Technique far exceeded Rin's expectations.
"Hahaha! Your defense finally doesn't work anymore!"
The Cursed Spirit looked at the wound on Rin's arm and burst into maniacal laughter, his azure pupils filled with mockery:
"Without your defense, how will you block my attacks? Now, it's time to show me your fear!"
He stared intently at Rin, expecting to see panic and fear appear on the young man's face, just like the Jujutsu Sorcerers he had defeated in the past.
But the next second, the smile on his face froze; Rin not only showed no fear but, covering his arm, threw his head back and let out a hearty, wild laugh.
"Wonderful! Absolutely wonderful!"
Rin's voice was full of excitement, his Crimson Sharingan fixed on the Cursed Spirit, like a hunter spotting his most precious prey:
"Adding a sure-hit effect without opening a Domain... this Cursed Technique is simply tailor-made for me!"
He instantly thought of Gojo Satoru's Limitless Cursed Technique.
If he could master this sure-hit attack, even when facing that unsolvable Limitless Defense in the future, he could directly hit the opponent's main body without opening a Domain!
This discovery made his blood boil, and the look in his eyes towards the Cursed Spirit was filled with undisguised desire, as if the opponent was not a deadly enemy, but a rare treasure that could make his strength leap forward.
The Cursed Spirit was completely bewildered by Rin's reaction.
He looked at the young man laughing uncontrollably before him, feeling the almost greedy gaze in his eyes, and involuntarily took two steps back, a strange chill rising from the bottom of his heart.
"You... are you crazy?"
The Cursed Spirit's voice trembled slightly:
"Your defense has failed; aren't you afraid I'll kill you?"
"Kill me?"
Rin slowly stopped laughing, his black hair wildly dancing behind him due to the surging Cursed Energy.
Black and red Cursed Energy began to gather in his palm:
"You can't die before you teach me this trick."
Before his words finished, Rin's figure suddenly shot out; this time, he no longer passively defended but actively launched an attack.
Black and red Cursed Energy surged towards the Cursed Spirit like a tide, the tomoe in his Sharingan spinning rapidly, not only capturing the opponent's trajectory but also frantically analyzing the principle of that sure-hit Cursed Technique.
The Cursed Spirit felt his scalp tingle as Rin rushed towards him.
He had originally thought he held the trump card for victory, but now he realized that this young man before him wasn't scared at all.
He was completely aroused by this powerful Cursed Technique, stirring up an even crazier desire.
The initiative in this battle had, unknowingly, undergone a revolutionary reversal.
