Although somewhat shocked, Indra had not forgotten what he was doing.
Suppressing his urge to question Isamu about Ninjutsu, he looked at him and said,
"Isamu, I admit that you're a genius. However, you should understand that for Dōjutsu users like us, Ninjutsu is secondary. Our eyes are our true power. Stop wasting time and show me just how strong your ocular power really is!"
Crack! Crack!
As he spoke, an enormous amount of purple Chakra erupted from Indra's body.
Massive skeletal structures rapidly formed around him.
Indra slowly rose into the air as his two-hundred-meter-tall Semi-Perfect Susanoo took shape, complete with flesh and legs.
"As you wish!"
Isamu's pupils contracted slightly.
A vast amount of blue Chakra burst from his body as well, and within moments, a blue Semi-Perfect Susanoo materialized around him.
"Oh?"
Garuda watched with great interest.
"So this is Uchiha Isamu's Susanoo? To be comparable to Brother Indra's… truly remarkable."
She knew Indra's strength better than anyone.
Since the departure of the Six Paths Sage, Indra had been the only person capable of fully awakening the power of the Sage's Eye.
Yet now, another individual capable of reaching the same level had appeared.
The situation was becoming increasingly interesting.
Inside the purple Susanoo, Indra floated calmly while holding a sword in one hand.
His Susanoo mirrored the motion.
In appearance, Indra's Susanoo looked nearly identical to the one Uchiha Sasuke would possess in future generations.
However, its power was on an entirely different level.
Meanwhile, Isamu floated inside his blue Susanoo.
Unlike Indra, he wielded a longsword formed from a Truth-Seeking Orb with both hands.
His Susanoo resembled Uchiha Madara's more closely.
It possessed a face on both the front and back and had four arms.
The two forward arms each wielded a massive sword.
BOOM! BOOM! BOOM!
Indra's Susanoo launched relentless attacks.
Isamu answered each strike without yielding an inch.
The giant swords collided repeatedly, causing the earth itself to tremble.
The basin, already situated below the surrounding terrain, continued sinking under the impact of their battle.
The destructive force produced by two two-hundred-meter Susanoo was terrifying.
And these weren't ordinary users.
They were both Six Paths-level powerhouses.
"Not bad, Isamu."
Floating within his Susanoo, Indra looked at him calmly.
"I can't say hearing that makes me happy."
Power suddenly surged within Isamu's eyes.
His Susanoo let out a thunderous roar.
Violent energy exploded outward, instantly forcing Indra backward.
At the same time, Isamu himself was pushed back several steps by the recoil.
Caught off guard by the sudden burst of power, Indra was forced to retreat multiple steps.
His Susanoo nearly lost its form.
After stabilizing himself, a strange light flashed in his eyes.
For years, he had fought countless opponents.
Aside from Ashura, no one had ever forced him back even a single step while using Susanoo.
Yet today, he had retreated.
And not just one step.
"Interesting, Isamu."
A slight smile appeared on Indra's face.
"Now I'm going to get serious."
"Prepare yourself."
The immense purple energy surrounding his Susanoo suddenly became unstable.
The giant sword disappeared entirely.
In its place appeared a massive blade formed purely from Chakra.
The purple Susanoo gripped the weapon with both hands and raised it high overhead.
Then it swung downward.
"Blade Aura Rampage!"
The enormous Chakra blade slashed through the air.
Instantly, five terrifying hundred-meter blade waves shot toward Isamu.
Faced with the attack, Isamu did not hesitate.
The remaining two arms of his Susanoo each formed another sword.
All four arms slashed simultaneously.
Four massive blade waves erupted forward.
BOOM! BOOM! BOOM! BOOM!
The blade waves collided head-on.
A devastating hurricane exploded outward.
The entire basin and surrounding mountain range shook violently.
The night sky was illuminated as though daylight had arrived.
"Ahhh!"
"This is insane!"
The weaker spectators were blown backward by the violent winds.
Many desperately clung to trees to avoid being swept away.
Seeing this, Garuda frowned.
"Your strength isn't sufficient to stay here."
"Retreat farther away before you're caught in the aftermath."
Truthfully, even she had not expected Isamu to possess such overwhelming power.
The fact that he could contend with Indra head-on was simply unbelievable.
"Understood!"
The spectators didn't hesitate.
They immediately fled farther into the distance.
Originally, they had come hoping to watch Isamu embarrass himself.
Instead, they had become the joke.
They couldn't even withstand the shockwaves from the battle.
What was there left to watch?
The four blade waves canceled each other out.
However, Indra's fifth wave continued forward.
"Hm?"
"There's still one left."
Isamu instantly reacted.
His Susanoo rolled aside.
The blade wave narrowly grazed its body.
Without losing any momentum, the attack continued onward.
It struck a mountain over a thousand meters tall in the distance.
BOOM!
A massive mushroom cloud rose into the sky.
The entire mountain collapsed instantly.
Nothing remained.
Seeing a thousand-meter mountain erased so casually, even Isamu felt a chill in his heart.
Such power was terrifying.
One slash had produced five massive blade waves.
Indra truly lived up to his reputation.
Using nothing but an Eternal Mangekyō Sharingan to reach the Six Paths level, his talent was simply monstrous.
If he ever awakened a Nine-Tomoe Rinnegan, his power would likely reach an entirely new realm.
"Oh?"
"You dodged it."
Indra looked down at the crouching Isamu.
"You've got some skill."
"But at this rate, neither of us will win."
"Where is your Perfect Susanoo?"
"Hurry up and use it."
"Perfect Susanoo?"
A faint smile appeared on Isamu's face.
He still remembered Madara's words:
Once the Eternal Perfect Susanoo appears, someone must die.
Because of that, he had no intention of using it until absolutely necessary.
Instead, he pressed his hands together and began rapidly forming hand seals.
Seeing this, Indra frowned.
"Isamu."
"Didn't I already tell you?"
"We are Dōjutsu users."
"Ninjutsu means nothing to us."
"No matter how powerful your Ninjutsu may be, it cannot break through the defense of my Susanoo!"
