Even begging meant waiting in line!

Over the past two years and more, Sasuke had successfully figured out the answer to that question.

To the Uchiha Clan, Susanoo was like an innate treasure vault. It lay hidden inside every Uchiha from the moment they were born, only locked away.

The Mangekyō Sharingan was its exclusive key, capable of opening the corresponding vault. More precisely, the vault was like a summoning device from Kamen Rider or Armor Hero, while the eyes were the thing you slotted into it.

For those with a Mangekyō Sharingan of their own, the vault opened the moment they awakened it. Afterward, they could use Susanoo whether they still had their Mangekyō Sharingan or not. Without that transformation device, however, even someone as powerful as Madara Uchiha could only manifest a muscular humanoid several sizes smaller when he had no eyes.

Those who did not have their own Mangekyō Sharingan could also use the corresponding Susanoo after obtaining a pair, though compatibility, their own chakra, and their Eye Power would limit it. Its original owner could draw out a hundred and twenty percent of its strength, while an outsider might only manage sixty to eighty percent.

Once he figured out who qualified to activate it, the next question followed immediately: how did you advance through Susanoo's different stages? After several more attempts with Shisui's eyes, gradually progressing from a skeleton to an upper body, Sasuke more or less discovered the issue.

In truth, there were only three limiting factors: Eye Power, chakra, and proficiency.

Susanoo was essentially formed from a special yin release chakra created by mixing Eye Power and chakra.

To activate Perfect Susanoo, you needed to push the Mangekyō Sharingan's Eye Power to its absolute limit and possess enormous amounts of chakra.

But training the Mangekyō Sharingan's Eye Power to its limit was basically a joke, because it came with one damned catch: use it too much, and you went blind.

To activate Perfect Susanoo, all you needed was perfect control over your Eye Power. In other words, you had to use Susanoo more often. Keep using it, and eventually you could activate its perfect form.

Normally, however, that was practically impossible with an ordinary Mangekyō Sharingan. Reaching the armored upper-body stage already meant you were exceptionally gifted. Any further use would wreck your eyes.

After all, the Mangekyō Sharingan was a defective product with unstable genes, doomed to collapse. By comparison, the Eternal Mangekyō Sharingan was a device upgrade. Originally, five minutes of charging bought you only ten minutes of use; with eternal eyes, five minutes of charging bought you two hours of talk time. Naturally, activating Susanoo and using dojutsu became much easier.

Still, while an ordinary Uchiha could only consider replacing the device if they wanted to activate the perfect form, now they had Sasuke, their Shapuaisi eye drops capable of replenishing Eye Power and vitality...

Want to activate the perfect form? Wasn't it just a matter of practicing often? Practice! I'll replenish whatever Eye Power you lose! I'll recharge whatever vitality you burn through!

Too much use would make you blind? Don't worry, kids. Guaranteed not to happen!

Of course, because of the devices' performance limits, three ordinary Mangekyō Sharingan users could not sustain the perfect form for long, and the drain on their Eye Power and chakra was enormous. Normally, all three would be half-blind after this fight, but Sasuke said it was no big deal.

Wasn't that all there was to it? At worst, he could drag Naruto along afterward, and the two of them could pump chakra into them together. If pure vitality and Indra's chakra were not enough, they would add Asura's to the mix!

It was only because Itachi had awakened his eyes relatively recently and spent somewhat less time practicing Susanoo that they did not have three Perfect Susanoo right now.

Presumably, the Third Hokage was already on the verge of a heart attack...

Heh heh heh heh.

"Let's go. We'll keep looking for Danzo. That blow just now should have given those guys concealing their presence quite a shock. Can you pick up any traces?"

Patting the wide-eyed Naruto, Sasuke looked around with some resignation. It was time to put learning Senjutsu on the agenda. His sensory abilities were still weak. Alternatively, he could try using Divine Mechanism Hundred Refinements to craft some Scientific Ninja Tools later.

"Huh? Oh, oh! Let's hurry up and find Danzo. My hands are itching for a fight too. Just now, I sensed a fleeting burst of exceptionally pure malice to the southwest. Maybe it's the guy we're after."

Snapping back to his senses, Naruto licked his lips, watching the three giants locked in combat with excitement surging in his chest. Using Mind's Eye of the Kagura and Malice Perception, he twitched his nose and pointed southwest.

"What are we waiting for? Come on, let's go beat up Danzo!"

Glancing once more at the three giants in the distance, Naruto wrapped himself in fierce winds that answered the thunder crackling around Sasuke. Wind and thunder erupted, and they vanished from the spot.

Their power seemed so great that the air they left behind warped slightly, swirling like a vortex.

Sent flying by the Heavenly Rock Cave, Shisui carved two deep furrows into the ground. He braced himself with one hand to steady his form, swept the Spiral Sword in his other hand across, then thrust it skyward.

"Susanoo: Ninety-Nine!"

In the next instant, countless green chakra arrows swarmed toward Fugaku from every direction!

Fugaku's Susanoo was engulfed in an instant, and Itachi beside him was not spared either. Unfortunately, both possessed defensive divine weapons exclusive to their Susanoo. With the Heavenly Rock Cave above one and the Yata Mirror above the other, they actually kept trading blows amid the rain of arrows.

Even with the special chakra-restoring ninja tools Sasuke had made, allowing him to waste a little chakra, Shisui could not help scratching his head after firing arrows for so long without accomplishing anything.

He really was just scraping their skin...

Watching the two ignore his attacks and keep hammering each other, Shisui's mouth twitched, and his competitive streak flared a little.

The wings on his back beat once, and he aimed the Spiral Sword straight at Fugaku, unleashing countless arrows again. Fugaku saw what Shisui was doing and threw his head back with another laugh, perfectly embodying the Uchiha's wild arrogance, looking down upon the world.

"Hahahaha! Come on, entertain me with your dance!"

Pitch-black wings spread, and the black Susanoo, likewise shaped like a Crow Tengu, soared into the night sky. It weathered Shisui's assault head-on and flew at him to attack!

Left on the ground was Itachi, who had consumed enormous amounts of chakra and Eye Power but still fell short of the perfect form, able only to glare helplessly.

Still, although he could not fly, he was not completely unable to join in.

After catching his breath, he instinctively imitated the pose Sasuke had demonstrated for him earlier and glared fiercely at Uchiha Fugaku's Susanoo. Countless black flames ignited across the black Susanoo's surface.

"Amaterasu!"

Amaterasu, the merciful flame that never went out yet had never killed anyone, was as underwhelming as ever, serving little purpose beyond interference. Still, it did successfully breach Fugaku's defenses, forcing him to expend additional Eye Power and chakra.

But... against three people who had all brought power banks... it was nothing more than adding wind with a fart...

That left Itachi on the ground, glaring helplessly in every sense of the word.

Yet to Sarutobi and the others, who were likewise staring helplessly, this scene looked entirely different.

Hiruzen Sarutobi looked up at the two behemoths fighting nonstop above Konoha. Their battle was ferocious; even the wind pressure from each clash was profoundly uncomfortable.

The commotion was already almost on par with the Nine-Tails' Attack back then. The entire village of Konoha could see it clearly. Pretending not to notice was utterly impossible.

At that moment, Hiruzen Sarutobi, completely unable to intervene, felt a particularly sharp pain in his balls.

Being able to fly was one thing, but why had they taken their fight into the sky? What the hell was he supposed to do now?!

Suddenly, he found himself missing his teacher, the Second Hokage Tobirama Senju, again.

Why hadn't Teacher developed a forbidden technique that let people fly before he died...?

Tobirama Senju: (눈_눈)

I'm begging you here! I can't fucking fly either!
