Watching the Spiral Sword appear, Kakashi's expression remained unchanged.
The Susanoo had taken another step toward completion.
But this was what made it interesting!
At this moment, the golden wind blades and flames faded from the White Fang, and lightning wrapped around Kakashi's body!
Lightning Release Chakra Mode!
As early as three years ago, Hiruzen Sarutobi had already handed over the entire set of Lightning Release Taijutsu to Kakashi, including the Hell Stab.
Although using Lightning Release Taijutsu to fight a Susanoo might seem a bit unqualified...
That depended entirely on whose Lightning Release Taijutsu it was!
When the Fourth Raikage faced Madara Uchiha's Susanoo, he could only take a beating. However, the Third Raikage had withstood a Wind Style: Rasenshuriken with his bare flesh!
Kakashi was naturally not the Fourth Raikage, but the Shisui Uchiha before him was not Madara Uchiha either!
"Die!"
Seeing Kakashi acting so arrogantly, actually intending to take the Spiral Sword head-on with his physical body, Shisui Uchiha roared in rage.
The Spiral Sword spun frantically, stabbing toward Kakashi with the momentum to destroy all things!
Azure lightning wrapped around Kakashi's body as he met the Spiral Sword head-on with absolute speed, only...
At some unknown point, a shade of purple dyed Kakashi's body!
It seemed like a while, yet also like a fleeting instant; the azure lightning around Kakashi transformed into soul-shaking purple thunder!
Purple Electricity!
A powerful technique derived from the Lightning Blade (Raikiri) by Kakashi in Boruto!
Whether in destructive power or piercing capability, it was far superior to the Lightning Blade!
Kakashi had been researching how to create Purple Electricity for a long time but had made no headway.
The only thing that gave Kakashi inspiration was Madara Uchiha achieving the Six Paths Mode.
Yin Release: Lightning Dispatch.
One could tell from the name that this was a technique fusing Yin Release and Lightning Release.
It further elevated the power of both nature transformations, using Lightning Release as the carrier and Yin Release as the essence. This brand-new technique attacked enemies over a wide range in a branching tree pattern.
Aside from this, Kakashi couldn't figure out how to create Purple Electricity.
But just now, having clearly understood exactly how Yin Release existed, Kakashi—who had already researched this for a long time—instantly comprehended the various principles within, as if enlightened by a sudden epiphany.
Already extremely skilled in Lightning Release, once he understood the essence of Yin Release, the birth of Purple Electricity came naturally!
It was just like how Madara Uchiha, who faced the Allied Shinobi Forces using only Fire Release, Wood Release, and the Sharingan, was able to immediately use several brand-new techniques like Yin Release: Lightning Dispatch and Gale Style: Light Fang upon achieving Six Paths Mode due to his understanding of Yin and Yang Release.
Purple thunder wrapped around Kakashi's body. At this moment, Kakashi's state could no longer be described simply as the Lightning Release Chakra Mode.
Based on the Lightning Release Chakra Mode, this current state was faster and stronger than Lightning Release Taijutsu!
As for what to name it...
Kakashi planned to ask Guy whenever he had free time.
But right now, the White Fang in Kakashi's hand hummed, seemingly in joy, delight, and excitement over this brand-new power!
"Rising Tiger: Thunder: Purple Electricity."
Endless purple thunder wound around the blade. The chakra aura radiating from that lightning caused Shisui Uchiha, who was currently in a state of madness, to feel a chill in his heart even through the Susanoo.
But at this moment, retreat was absolutely impossible!
"Die!"
Like a roaring beast, the Susanoo let out a hideous low growl as the Spiral Sword in its hand collided with the Purple Electricity!
Purple and green intertwined.
Lightning and fire entangled.
Piercing force and rotation collided.
An instant became eternity!
The moment the two touched, the outcome was already revealed.
Wrapped in violent thunder, the White Fang crushed the Spiral Sword—which was dozens of times larger than itself—like it was smashing rotten wood!
It even went on to shatter the Susanoo's entire arm!
Shisui Uchiha looked at this scene in disbelief. He could not accept that the power granted to him by his family bloodline was inferior to Kakashi, who possessed no Kekkei Genkai!
"Die for me!"
Amidst Shisui Uchiha's roar, the crimson magatama on the chest of the half-body Susanoo once again erupted with its previous power!
However, for Kakashi, who was now clad in the Lightning God Armor, this move no longer posed a threat.
Especially since the essence of the lightning in this Lightning God Armor had been changed to a combination of Yin Release and Lightning Release.
The two could not be mentioned in the same breath.
With just a Body Flicker, purple thunder erupted violently, and countless clouds of steam were trampled out of the lake surface beneath his feet!
What?!
Shisui Uchiha was both shocked and furious. The Mangekyō, which had been able to detect Kakashi's movements just moments ago, could surprisingly no longer capture his figure!
"This is the end, Shisui."
When Kakashi reappeared, he was already in mid-air. He slashed out a single stroke!
Violent purple blade light engulfed the field of vision. The lightning pierced through the Susanoo's body, and the sharp edge sliced open the defense the Uchiha Clan took the most pride in!
With just this one slash, the Susanoo disintegrated instantly!
The residual power of that slash transformed into thunder, instantly sweeping over Shisui Uchiha's body!
Shisui Uchiha, wrapped in lightning, growled hoarsely, trying to erupt with Susanoo once more.
But the White Fang was already pressed against his neck.
The winner was decided.
"You..."
Shisui Uchiha looked at the man before him, his lips moving, wanting to say something.
A pale white blade light flashed and vanished.
The massive head sank into the water.
Shisui Uchiha's broken body crashed to the ground, his bright red blood dyeing the lake a piercing crimson.
Looking at Shisui Uchiha's headless corpse, Kakashi flipped his wrist. A sealing scroll appeared, and he sealed Shisui Uchiha's body inside without hesitation.
Glancing at the head sinking to the bottom of the lake, Kakashi raised his hand and brought the blade down.
The head, along with the Mangekyō Sharingan, shattered apart and was devoured by the fish in the water.
Having done all this, Kakashi did not linger and turned to leave.
Now that Shisui Uchiha was dead, there wouldn't be any abnormalities in the short term. But once it exceeded three days, the Uchiha Clan would definitely make a move.
As one of the rare experts within the clan, Shisui Uchiha's every move could affect the hearts of the Uchiha.
Without having taken on a mission, a ninja—even if training—could not simply vanish for three days.
When that time came, he could toss Shisui Uchiha's body out to cause chaos among the Uchiha.
Then, by making trouble from the inside, he could detonate this barrel of explosives.
At that point, Kakashi would have a justifiable reason to eliminate the hawks within the Uchiha Clan.
It was just that at that time, Danzō Shimura would certainly use the opportunity to lead the measures he had already prepared to attack Kakashi.
But compared to the Uchiha Clan, Danzō Shimura was even filthier.
To deal with that guy, Kakashi wouldn't even bother finding an excuse. He just needed to go into the Konoha archives and dig out the Root's movements during the Nine-Tails' attack, as well as evidence of the other party assassinating the Third Hokage.
Once the Uchiha Clan and Danzō Shimura fell, the remaining Koharu Utatane would be even easier to handle.
He just hoped that old hag wouldn't fail to appreciate his kindness.
