"We'll win!" Obito's heart was filled with confidence.
The undefeated legend of Shisui in internal battles is already a thing of the past; he has undergone multiple transformations amidst various unexpected events. Obito is confident he can defeat the two-year-younger Shisui.
Although Shisui activated his Sharingan earlier, Obito was the first to reach the Three Tomoe level—proof that he has surpassed Shisui.
Obito was already pondering who his opponent in the second round would be.
Obito and Shisui walked together to the open field, assuming their stances and forming the Seal of Opposition.
"Begin!" Nohara Rin shouted after seeing that the two were ready.
As soon as Rin's voice fell, both of them intensely concentrated their breaths to enhance physical abilities, and with Instant Body Jutsu, charged at each other.
Bang bang!!
Fists and feet intertwined, constantly producing sounds of bodily collision, making it difficult to determine a victor for the moment.
At that moment, Shisui suddenly shifted to defense and seized the opportunity to use Instant Body Jutsu to widen the distance.
He understood his strengths and weaknesses; due to his younger age, Obito's body was taller. Though it seemed like an impasse, prolonged combat would be advantageous for Obito.
"Fire Release: Great Fireball Jutsu!"
Obito did not choose to chase immediately because he knew Shisui excelled in Instant Body Jutsu. A blind pursuit could lead to mistakes.
A large amount of Chakra gathered in Obito's throat, and then instantly transformed into Fire Attribute Chakra, spewing out as flames.
Whoosh!!
A massive orange-red fireball quickly formed, towering five meters high, and struck towards Shisui.
As an Uchiha who frequently uses the Great Fireball, Shisui knew all its characteristics. To conserve Chakra, Shisui did not use Ninjutsu to neutralize it but used his agile maneuvering to evade.
Generally, Shisui's Chakra is abundant, and there's no need for special conservation since as an Uchiha with Three Tomoe Sharingan, he has much more Chakra than ordinary ninjas.
However, this battle is different; Obito, his opponent, also has Three Tomoe Sharingan as an Uchiha. He wanted to use Armament to break the stalemate, so he must reserve some Chakra for Armament Aura.
Seeing Shisui not using a Fire Release to neutralize the Great Fireball but instead chosen to dodge, Obito quickly launched a ferocious attack, first unleashing numerous shurikens followed by Instant Body Jutsu advancing to launch various swift Taijutsu attacks.
When using the Great Fireball, Obito had already prepared two attack plans.
If Shisui uses Fire Release to neutralize, he will immediately use a stronger Fire Release to suppress. Obito is confident in his Fire Release as he can enter the Breath of Flame Chakra Mode.
If Shisui avoids confrontation, Obito will take the opportunity to deplete more of Shisui's stamina and inflict some minor injuries.
Faced with Obito's swift offensive, Shisui calmly opened his Three Tomoe Sharingan to enhance his abilities.
Obito also immediately concentrated Chakra, activated Sharingan, and continued to maintain his suppressive stance.
"Indeed, I'm stronger now," Obito thought to himself.
He had judged his superiority based on Kakashi's previous battle with Shisui, but because it had been a long time since that fight, and Obito hadn't sparred with Shisui during this period, before the battle, Obito only strategically underestimated Shisui, not feeling entirely confident about victory.
After several rounds of exchanges, Obito could confirm Shisui's strength was inferior to his; in overall ability, he had surpassed Shisui significantly.
Testing concluded, Obito focused his breath to the utmost, entering the Breath of Flame Chakra Mode, preparing to defeat Shisui in one go.
The Breath of Flame Chakra Mode not only greatly enhances Nature Transformation capabilities and strengthens Fire Release power, but also significantly boosts physical capabilities, with almost no drawbacks except for high Chakra consumption.
Feeling the endless power surging within his body, Obito couldn't help but smile.
In the Breath of Flame Chakra Mode, he can unleash Fire Release without forming seals, and its power is immense—what could Shisui use against him?
"Fire Release: Impatiens Fire Jutsu."
Obito clasped his hands together, then opened his mouth to unleash a barrage of small fireballs towards Shisui.
Shisui quickly retreated, his hands moving rapidly, finally succeeding in using Ninjutsu as the numerous fireballs were about to reach him.
"Fire Release: Impatiens Fire Jutsu!"
Though they used the same Ninjutsu, with Obito already in Breath of Flame Chakra Mode, not only was the number of fireballs more than Shisui's, but even their size was significantly larger.
With the same Nature Transformation, and even the same Ninjutsu, naturally, the stronger one wins. Obito's fireballs crushed Shisui's and continued to strike towards him.
Facing such a wide-ranging attack, Shisui could only try to protect himself with Chakra and frantically maneuver.
But the distance was too close, making Shisui invariably take damage, and Obito's Sharingan clearly saw Shisui's injuries.
"Shisui, although I count as your clan brother, I can't let you off in matters like this." Obito felt a little guilty, believing victory was certain.
Thinking about the many tasks he'd have to do if he failed, the little guilt in Obito's heart quickly disappeared, exploding with Chakra as he charged straight at Shisui.
Before injury, Shisui barely managed a fifty-fifty Taijutsu fight against his normal state, but now Obito had entered Breath of Flame Chakra Mode and Shisui was injured, giving Obito a ninety-ten advantage.
Actually, Obito felt it was a total victory, but he thought it might seem a bit arrogant, so he generously gave Shisui a ten percent chance.
