Sarutobi Hiruzen and Mitokado Homura, among others, did not interrupt the battle, merely watching silently from the side.
The shurikens both carried were soon exhausted, for a ninja couldn't carry hundreds of shurikens on them, only about the same amount.
However, Uchiha Fugaku had slightly more shurikens, with the last two being caught by Uchiha Yoichi through the center hole with his fingers, then thrown back again.
"Almost evenly matched..."
The Second Elder murmured, not interrupting the two battling; however, the earlier shuriken throwing technique was quite impressive, even his Sharingan in the dark could hardly capture all the shurikens, yet the two in battle saw it clear as day.
After the shuriken throwing ended, Uchiha Fugaku and Uchiha Yoichi almost simultaneously performed Sealing, planning to decide the battle with Ninjutsu.
Uchiha Masato to the side said with a slight frown: "Why is Mr. Yoichi slower?"
Though very brief, they still noticed it.
Uchiha Kenji said softly: "He wants to defeat the opponent with the same Ninjutsu that Fugaku uses, so he's waiting for Fugaku to complete his Seals..."
This is a very confident display, and Uchiha Yoichi had no intention of using his best Taijutsu from the beginning—or else Uchiha Fugaku would lose even faster, as the Konoha Lightning Fang is renowned for swordsmanship and speed.
However, being slow by one second has its disadvantages; if the Ninjutsu is the same, the opponent might seize the initiative.
"What is that..."
The distant watching Uchihas all showed surprise, while Sarutobi Hiruzen and the others couldn't see anything, as they did not have the Sharingan and couldn't see the Chakra changes in Uchiha Yoichi.
Upon completion of Sealing, a surge of much stronger Chakra erupted from within Uchiha Yoichi's body, resembling the scorching heat of a volcanic eruption to them.
"Fire Release: Great Fire Extinguishing!"
"Fire Release: Great Fire Extinguishing!"
Two masses of flame, so hot they could burn everything, spewed forth, instantly dyeing the dark night sky with the redness of the fierce flames.
Upon the collision of the fire seas, the flames scattered instantly.
However, at the moment the flames collided, even without Sharingan, the onlookers could clearly see that Uchiha Yoichi's Fire Release was stronger than Uchiha Fugaku's, and significantly so!
'Not good!'
Uchiha Fugaku's vigilance surged, for if his Great Fire Extinguishing was just a dozen meters of flame, then Uchiha Yoichi's was a sea of fire thirty to forty meters wide.
In an instant, his Great Fire Extinguishing was consumed and, along with the fire he spewed, surged toward him.
Dodging was already too late, the range was too broad, the power too great, and Uchiha Fugaku couldn't use Water Release. In an instant, he made a decision, and the Three-Tomoe in his eyes quickly transformed into the Mangekyo Sharingan.
Swish swish!
A waterfall-like torrent suddenly appeared, directly extinguishing Uchiha Yoichi's Great Fire Extinguishing.
"Water Release?"
Not only Uchiha Yoichi was stunned, but the observing Great Elder, Elder Kenji, and others were also surprised, as they remembered that Uchiha Fugaku couldn't use Water Release.
"No, it's not Water Release!"
Uchiha Yoichi saw Uchiha Fugaku's Mangekyo Sharingan and said affirmatively, "This must be your Mangekyo ability, capable of creating Water Release... or rather, it's similar to Izanagi, a Pupil Technique."
"Chigaeshinohokami, it allows me to convert the Illusion Techniques I create into real phenomena, indistinguishable from reality!"
Uchiha Fugaku sealed his hands again, continuing to refine Chakra, "With this Pupil Technique, I am invincible!"
Rumble!
A bolt of lightning struck from the sky, but disappeared suddenly after striking Uchiha Yoichi; it was a Genjutsu.
Boom boom!
Stone spikes erupted from the ground around Uchiha Yoichi, attacking his abdomen directly, but in the next moment, they were shattered by the Lightning Armor that suddenly wrapped around Uchiha Yoichi's body.
Uchiha Yoichi had already broken free from that Celestial Thunder Genjutsu.
"Impressive Pupil Technique, those stone spikes felt like real Earth Release, and that waterfall, so you can use Pupil Techniques to unleash all Ninjutsu, and Sealless ones at that..."
Uchiha Yoichi quickly discerned the nature of the Chigaeshinohokami Pupil Technique, realizing its true power wasn't just in the instant release of Sealless Ninjutsu, but like Yin-Yang Release, if enough Pupil Power was available, it could create anything.
"This is just the beginning, Uchiha Yoichi!"
Boom boom boom!
The ground on both sides of Uchiha Yoichi suddenly shook, then from his body emerged towering earthen walls like clamps, intending to trap him.
"Mountain Earth Jutsu of the Hidden Rock Village?"
From afar, Sarutobi Hiruzen showed shock upon seeing Uchiha Fugaku use this Jutsu; the earlier Water Release had already surprised him, and now Uchiha Fugaku was using an Earth Release he had never used before.
And it was Advanced Earth Release Ninjutsu, something even he couldn't use.
Uchiha Yoichi propped apart the gigantic earthen walls with his hands, wrapped in the powerful Lightning Armor; although strong, the Earth Release wouldn't affect his Lightning Armor.
The earthen walls didn't completely close, leaving a gap just wide enough for one person before stopping, seemingly meant to fix Uchiha Yoichi in this line.
Seeing he and Uchiha Fugaku aligned, Uchiha Yoichi's face displayed exaggerated panic, "Not good!"
"Too late, try my other Pupil Technique, Amaterasu!"
Blood vessels appeared in Uchiha Fugaku's right eye's Mangekyo, and blood even seeped from the corner of his eye—a black flame appeared where his gaze converged.
Originally aimed at Uchiha Yoichi's head, but suddenly blocked by the hand he extended.
"Ah...."
Hearing the scream, Uchiha Fugaku gasped, "Heh, the Amaterasu Fire burns everything, can never be extinguished. Although it didn't hit your head, your arm is finished—this battle is your loss!"
"Ah, so I've lost?"
The scream disappeared from Uchiha Yoichi's face, suddenly turning very calm, even with a hint of a smile.
Uchiha Yoichi then shook his arm, unable to shake off the Amaterasu Fire, then said, "Uchiha Fugaku, your two Pupil Techniques are formidable, but you just awakened the Mangekyo, shouldn't have been eager to challenge me..."
"For instance, with this Amaterasu, at least shave off a layer of flesh and it no longer threatens me..."
Afterward, Uchiha Yoichi condensed a Lightning Release Chakra Blade with his left hand, swiftly sliced off the skin attached to the Amaterasu Fire.
This ruthlessness caused Uchiha Fugaku to tremble slightly upon witnessing, but he steeled himself before speaking: "Your right hand's already useless, with what now do you..."
Before finishing, Uchiha Fugaku watched amazed as Uchiha Yoichi's right hand rapidly regenerated, within just five seconds it looked as good as new, as if it had never been injured.
Ōmononushi no kami, where the gaze fixes, life is bound to appear.
Uchiha Yoichi had planned to try out this Pupil Technique, hence why he hadn't evaded the Amaterasu with speed earlier, and now it seemed the effect was satisfactory.
"This, this is your Mangekyo Pupil Technique...."
Looking powerless, Uchiha Fugaku realized that even with the joint power of his two Pupil Techniques, he couldn't take down Uchiha Yoichi, and that was despite Yoichi not having used Taijutsu or Swordsmanship.
"Next up...."
"Next, it's time for the final move—I have no interest in wasting more time with you, Uchiha Fugaku."
After speaking, Chakra surged from Uchiha Yoichi's body, rapidly forming bones, muscles, and armor, from a semi-humanoid into a full sixty-plus meter tall Susanoo form.
With wings on its back, a sword at its waist, deep blue Chakra armor resembled a divine being under the night sky, as Uchiha Yoichi stood atop Susanoo's head, looking down at Uchiha Fugaku.
"It's your turn, Uchiha Fugaku!"
