The dense green Chakra surged around Shisui, quickly forming a half-skeleton over four meters tall, overlooking all creatures around him.
"What kind of Ninjutsu is this?!" Yamato exclaimed in shock.
He had only been in school for a few months, yet these seniors seemed as if they had been cultivating for years, each reaching new heights of strength.
"It's truly a powerful Kekkei Genkai; besides Dojutsu, it possesses such formidable abilities."
Seeing Shisui use Susanoo, Kakashi couldn't help but recall Uchiha Madara's eighty-meter-tall blue giant, a power that was truly despair-inducing.
However, Kakashi estimated that reaching the level of Madara's Susanoo should be quite difficult. Before Senju Hashirama became strong, the Uchiha Clan only stood equal to the Senju Clan.
"Shisui actually mastered it. I originally wanted to save my first usage for Kakashi." Obito thought to himself, feeling a hint of regret.
He had intended to catch Kakashi off guard with Susanoo, but now he had to use it.
If he entered the Breath of Flame Chakra Mode to use Green Flame, he could probably break through this level of Susanoo's defense. However, Shisui also knew Green Flame, and used it even better than he did.
"Susanoo!"
Obito erupted with a massive amount of Chakra, as light blue Chakra surged around him, rapidly forming a light blue Susanoo similar in size to Shisui's Susanoo.
Bang!!
The massive fists of the two half-skeleton Susanoo collided, the air from the collision causing the surrounding leaves to rustle noisily.
"Turns out Obito knows it too." Shisui wasn't too surprised.
They had unlocked the Mangekyo Sharingan together, so it was normal for Obito to master Susanoo.
"Even Obito-senpai knows this!" Yamato felt overwhelmed.
He felt immense pressure; with seniors like these being so strong, how long would it take for him to catch up—or would he ever catch up?
He truly bought into Shimura Danzo's nonsense. With seniors around, Konoha wouldn't need him to protect it.
Boom!!
Under the control of Shisui and Obito, the green and blue skeleton giants fought fiercely, shattering the ground beneath them.
But the two had similar Dojutsu strengths, both having only recently mastered Susanoo, so the battle reached a stalemate once again.
"Sorry, Shisui, but since you were born two years later, don't blame me for using this tactic." Obito felt a little guilty.
He preferred winning honorably rather than using such tactics.
But he truly wanted to become the strongest disciple, so he had to use strategies when necessary.
Just as Obito thought of prolonging the standoff, Shisui's attack style suddenly turned aggressive, causing both skeleton Susanoo to develop numerous cracks.
"Susanoo·Dominating Fist!"
Shisui suddenly unleashed a massive amount of Chakra, allowing a substantial flow of Armament to the Susanoo's fists, hardening them by enveloping them with a significant amount of Armament Chakra.
His Armament color had always been the strongest within the team, and exceptionally so, but he previously lacked enough Chakra to fully utilize it.
Now with abundant Chakra, he researched combining Armament with other abilities.
A black and blue pair of giant fists collided, and the blue fist instantly shattered, dissolving into light particles dissipating in the air.
Obito immediately thought of using Armament on his Susanoo for defense but suppressed the idea when he realized something.
Crunch!!
The dark giant fist relentlessly struck Obito's Susanoo, causing it to crack all over retreated within its body until it fractured and vanished.
Finally, the massive black fist smashed toward Obito.
Confronting the giant black fist that almost matched his height, the unarmed Obito felt exceptionally helpless.
"Rumble!!"
A huge explosion sounded, the ground shattered more severely under the blow, mud and stones shot out in all directions, dust smoked, and yellow haze permeated the air.
"Did Shisui-senpai win?" Yamato vaguely saw a hint of green in the yellow fog, which was Shisui's Susanoo.
Kakashi shook his head, knowing Obito's Mangekyo ability wouldn't be easy to resolve.
As Kakashi predicted, after the smoke cleared, Obito stood in front of Susanoo without visible injuries.
Whew!
Shisui hadn't thought he could resolve Obito so easily, continuing to manipulate Susanoo to smash towards Obito.
"Breath of Flame Chakra Mode!"
Obito maximized his breath, greatly enhancing his physical and Fire Release capabilities.
Swish!
Obito swiftly touched his toes to the ground, dodging Susanoo's attack, while converting a large amount of Chakra into Fire Attribute Chakra.
"Fire Release: Green Flame!"
The incredibly high-temperature cyan flame spewed from Obito's mouth, transforming into a cyan thread shooting towards Susanoo.
Shisui immediately manipulated Susanoo's left hand to shield in front of him; Obito aimed at the position where his body was.
"Indeed, that blow consumed a lot of Shisui's Chakra!" Seeing Shisui didn't use Green Flame to counter, Obito thought internally.
He hadn't used Armament to enhance Susanoo's defense because he considered something.
His Armament wasn't as strong as Shisui's, and using Armament on something as large as Susanoo also consumed more Chakra.
Using Armament was not as good as directly ignoring Susanoo and avoiding attacks with Void Kamui.
Having consumed a lot of Chakra, Shisui certainly couldn't maintain Susanoo for long, nor could he use Fire Release to counter his Green Flame.
Under the terrifying high temperature of Green Flame, Shisui's Susanoo, already slightly cracked, developed more significant openings.
Facing the damaged Susanoo, Obito felt significantly less pressure, using Void only once to exhaust Shisui until unable to maintain Susanoo.
Seizing the chance when the situation was dire, Obito unleashed Chakra and charged at Shisui.
Shisui struggled to resist, but due to overconsumption of Chakra and stamina, he soon fell into a disadvantage.
Obito seized Shisui's attacking fist with his left hand, and his right fist was about to smash through Shisui.
"Will Obito-senpai win?" Yamato felt surprised at the turn of the battle.
Bam!
Just then, a stone next to them transformed into Shisui's form, fiercely swinging a fist covered by Armament at Obito's side waist.
Shisui knew Kamui was troublesome, so why had he spent a large amount of Chakra destroying Obito's Susanoo? To look cool?
Of course not, because his goal wasn't just to break the impasse; he also wanted to use himself as bait, drawing Obito into a trap.
If he was in a good state of health, Obito would certainly be very cautious, using the most stable method to win against him.
Conversely, if his stamina and Chakra were mostly depleted, Obito wouldn't miss the opportunity to strike while Shisui was down.
So, amidst Susanoo's attack and the cover of dust, Shisui split out a Shadow Clone, having it use Transformation Jutsu to hide around him waiting for a chance.
Kamui void was indeed very powerful, but Obito had to revert to physical form when attacking, thus presenting the Shadow Clone a chance.
"A senior is always a senior."
Seeing the battle twist again, Yamato conceded; he truly didn't know who would win.
"I want to be first!"
At this critical moment, Obito's eyes shook violently, completing Void Kamui at an unprecedented speed.
The dark fist of Shisui's Shadow Clone pierced through Obito's body, as if hitting an illusionary specter.
Bam!
Obito, like a ghost, passed through Shisui's Clone, then physically grasped Shisui attempting a final struggle with the other hand and punched fiercely.
Shisui's body flew backwards and crashed to the ground, and the Shadow Clone dissipated.
"Obito wins."
Mokgetsu announced the result of the battle.
"Whew." Obito panted heavily, sitting down directly on the ground.
Even now, he could still feel his heart racing; it was truly thrilling just now. Had Shisui's Clone moved a little faster, the outcome might have been completely different.
