This wave of attacks was clearly the result of Obito's careful planning, rather than a stroke of luck.
Namikaze Minato felt that as long as the opponent's strength was not much superior to Obito's, most ninjas in the Ninja World, unaware of Obito's intel, would fall prey to this trick.
The quick release of Breath of Flame Chakra Mode without seals really has an advantage in one-on-one situations.
Boom! Boom! Boom!
The three Kakashis strangled by flames all turned into white smoke and dissipated in front of everyone.
"Eh, how come they're all Shadow Clones?" Yamato looked surprised.
He had been worried just now that Kakashi might suffer serious injuries from this Fire Release, but unexpectedly all three Kakashis were clones.
The next moment, a hand silently reached out from behind Obito.
Whoosh!
Obito's body moved swiftly, causing Kakashi's hand to miss.
Realizing that Obito had discerned his strategy, Kakashi did not hesitate for a moment, immediately erupted with chakra and rushed forward, raising his hand to strike Obito.
Crackle!
Dazzling purple lightning appeared in Kakashi's palm, transforming it into a purple lightning blade.
"Fire Release: Flame Fist!"
Obito compressed the flames onto his fist and fiercely swung a fire fist to meet Kakashi's lightning palm.
Clatter!
Rumble!
Purple arcs and fiery sparks continually shot out to the surroundings, a violent explosion sounded.
The powerful impact forced Obito and Kakashi to simultaneously retreat a distance.
"Heh heh, Kakashi, this time I've seen through all your intentions. Let's see how you're going to win this time," Obito felt immensely proud.
Though it looked even now, he was actually in the lead.
Because Kakashi's endurance in battle was inferior, just dragging it out like this would ensure Obito's victory.
The most satisfying thing for Obito was that he successfully saw through each of Kakashi's attacks.
Kakashi used to always say he only charged without tactics; he wanted to see what Kakashi would say after losing this time.
"Three Shadow Clones, one Purple Lightning, I want to see how many more attacks you can organize," Obito silently calculated Kakashi's remaining chakra amount.
The chakra consumed by Earth Flow Wall wasn't much, but Purple Lightning took a lot.
Following up, Obito dismissed Breath of Flame Chakra Mode.
Using Sharingan alongside Breath of Flame Chakra Mode was too extravagant; usually, one alone sufficed.
"Earth Release: Rock Pillar Spear!"
Kakashi, whom Obito thought would lose, still maintained the previous attack rhythm, soon launching another assault on Obito.
Kakashi didn't use Breath of Thunder Chakra Mode, but employed many different abilities.
The combination of these various Lightning Release, Earth Release, and high-speed swordsmanship caused considerable trouble for Obito, but couldn't bring him down.
Obito's smile grew wider.
"Haha, using so many ninjutsu, even if he enters Breath of Thunder Chakra Mode next, he won't have extra chakra to use ninjutsu," Obito laughed crazily inside, already seeing the victory scene.
In his view, Kakashi underestimated his opponent in this fight, treating him like the old Obito, wrongly assessing his resilience.
"Let me teach you a painful lesson."
"Fire Release: Great Fireball Jutsu!"
Obito opened his mouth and spat a huge fireball towards Kakashi, whose chakra was almost spent; it was Obito's turn to attack.
Whoosh!
Facing the incoming fireball, Kakashi opted for Instant Body Jutsu to dodge.
Obito, on the other hand, pursued relentlessly, exploding with chakra and chasing after him.
The fight suddenly reversed, both sides changing roles.
"Could Obito win this time?" Nohara Rin felt a bit surprised; she favored Kakashi more.
Of course, it wasn't looking down on Obito; it's just that Kakashi had shown better performance previously.
"Not necessarily; Kakashi hasn't used Breath of Thunder Chakra Mode yet," Might Guy shook his head.
He believed Kakashi would win this time.
If you ask why, it's because of an instinct for his close friend!
"Breath of Flame Chakra Mode!"
Taking advantage of the situation, Obito re-entered Breath of Flame Chakra Mode, intending to go all out and defeat Kakashi within two minutes.
Facing the aggressive Obito, Kakashi pressed both his palms together, intertwining the ring finger and pinky, extending the other three fingers straight to form a Tiger Seal.
"Yang Seal: Release!"
With Kakashi unlocking the Yang Seal, the massive chakra sealed within automatically channelled the Breath of Thunder Chakra Mode, greatly enhancing Kakashi's physical ability and aura.
"Hmm?" Obito sensed something was amiss.
The Sharingan, while not as precise as the Byakugan for observing chakra, could still estimate generally.
"This can't be right; how can Kakashi still have so much chakra? Where did he get all that chakra!"
Obito stared at the massive chakra erupting from Kakashi's body, astonished and puzzled.
This was the same Kakashi who used to collapse after one full-force slash, right? Obito wanted to report Kakashi for cheating; how could someone increase their chakra so much in a short time?
"Haha, truly a close friend," Might Guy laughed heartily, crossing his arms.
"Time to prepare a stronger new move for a close friend," Might Guy thought.
Recently, Might Guy planned to utilize all his Taijutsu knowledge, developing a whole new Taijutsu, one that can only be used when Breath of Rock Chakra Mode and the Sixth Gate of Eight Gates are combined.
Though Mokgetsu taught excellent Taijutsu, Might Guy believed creating himself was meaningful.
Because he understood his own body the best, the ninjutsu he developed is sure to suit him perfectly.
Additionally, when he grows up, he can teach it to his disciples.
Kakashi drew out the White Fang Short Blade from behind, stepping half-forward with his right foot, sliding his left foot back, while tilting his body to the left in sync with the motion.
"Flash Step: Divine Speed!"
Brilliant yellow lightning exploded on Kakashi, propelling him like a real bolt of lightning.
Sensing the situation, Obito had already begun retreating, but for the rapidly bursting Kakashi, the distance was too short, quickly catching up to Obito.
"Fire Release: Fire Dragon Flame Bomb!"
Obito hurriedly relied on the support from Breath of Flame Chakra Mode, rapidly converting burning chakra into Fire Attribute Chakra, spitting out a massive flame to stop Kakashi's approach.
"Thoughtless Slash!"
Purple lightning continuously cycled from Kakashi's palm to the White Fang Short Blade, elongating it into a purple Tachi.
Crack!
A crisp and bright lightning sound emerged, a dazzling purple slash flashed, splitting the flames directed at Kakashi in two, immediately dispersing.
Bang.
Before everyone figured out the reason for Kakashi's impressive display, Obito fell to the ground, a scorch mark with lightning evident on his chest.
However, when everyone noticed the ground ahead of Obito, they knew Kakashi showed mercy.
The ground before Obito became a scorched black rut.
If Kakashi's slash hit Obito directly, they might have ended up with two halves of Obito instead.
"Remarkable, such a slash, even White Fang-senpai might not manage," Namikaze Minato was amazed in his heart.
Judging by the single attack output capability alone, Namikaze Minato felt White Fang might not necessarily surpass current Kakashi.
Of course, Kakashi's overall strength is certainly at a significant gap, as a ninja's true power is gauged by overall ability, not just high single output.
Nevertheless, Namikaze Minato felt this was already extraordinary, considering Kakashi was merely a teenager, not an adult in his twenties.
"Kakashi wins." Mokgetsu announced the result.
For Mokgetsu, who knows everything, this was a fight without suspense.
After mastering the Yang Seal, Kakashi in full condition was at a different level from Obito.
Kakashi had always been limited by chakra amount; the additional chakra from the Yang Seal held great significance for him.
PS:
This session really turned into an endless battle.
Managed to finish by half-past three.
