The Future SS-Rank Ninjutsu

While Izayoi and Hinata were accompanying Hanabi on a shopping trip.

Beneath a massive waterfall along the Naka River near the Uchiha Clan.

If a member of the Hyuga Clan were here and activated their Byakugan, they would discover a cave beneath the waterfall.

At that moment, tremendous noises echoed from within the cave, though they were concealed by the roar of the waterfall.

If one touched the rock walls around the waterfall, they could also feel the occasional tremors.

A blue glow tore through the darkness within the cave.

A blue-white sphere rapidly swelled, like a water-filled balloon.

Then, the basketball-sized energy sphere flew into the darkness.

Boom—

As the explosion rang out, shockwaves roared and gravel scattered everywhere.

The Dust Mist did not rush out of the cave before being dispersed by the gusts.

Once everything had settled, another energy sphere appeared and shot deeper into the darkness, setting off another violent explosion.

The cave had clearly been blasted open by energy spheres like these.

"The core is complete. Next, I can create smaller spheres inside it."

Izayoi's Shadow Clone appeared at the illuminated cave entrance, sorting through today's gains.

Izayoi had already grasped the basics of the anime-original Super Hurricane Combination Sphere: enlarging the Rasengan to a size second only to the Big Ball Rasengan.

This had taken Izayoi a full two years.

Izayoi finally understood why Naruto Uzumaki still needed Shadow Clone assistance to use the Big Ball Rasengan after training for three years.

For someone who could not even perform a one-handed Rasengan, turning it into that size while maintaining its balance and keeping the chakra from exploding was practically impossible.

Even Izayoi had spent two full years raising his Chakra Control to this level.

If it were merely a matter of gathering chakra together into something so massive, it would not have been especially difficult.

The hard part was gathering so much chakra together and making it spin at ultra-high speed.

This was practically hell-level difficulty!

After all, the Rasengan was already the pinnacle of Shape Transformation, with an A-rank learning difficulty.

The Big Ball Rasengan was definitely somewhere between A-rank and S-rank.

No wonder S-rank ninjutsu were called ultimate techniques that could not be mastered with absolute certainty, no matter how much effort one put in or how great one's talent was.

Simply creating such a large energy sphere was already this difficult.

Creating five spheres within it would be no less difficult than Naruto Uzumaki perfecting Wind Release: Rasenshuriken.

Then simultaneously injecting five different Nature Transformations into those five smaller spheres... just thinking about it made his head hurt.

If he succeeded, setting aside its power for now, its learning difficulty would definitely exceed S-rank—SS-rank.

Even Asura Otsutsuki could not accomplish that.

Yet it had become Izayoi's goal.

His current potential was even more astonishing than that of Asura Otsutsuki, who had needed to obtain power from Hagoromo Otsutsuki.

If purple-grade Chakra Control was not enough, then he would raise the Chakra Control Talent Perk to gold grade.

As long as he successfully developed the Super Hurricane Combination Sphere, he would be able to rely on a single move for everything, just like Naruto Uzumaki.

No matter what enemy he faced, he could solve it with a Rasengan.

Sitting cross-legged before the waterfall, Izayoi's Shadow Clone continued gathering chakra between his hands, creating a basketball-sized energy sphere. This time, however, he did not throw it.

Only after training until he had no chakra left did the Shadow Clone turn into a puff of white mist and vanish.

All the fatigue and experience fed back to the Main Body.

Izayoi, who was holding Glutinous Rice Balls and feeding them to Hanabi, merely raised an eyebrow before returning to normal.

Even Hinata, who had been secretly watching him the entire time, did not notice the change in Izayoi.

Ever since mastering the Rasengan and attempting to develop the Super Hurricane Combination Sphere, Izayoi had rarely trained with his Main Body.

He always had his Shadow Clones train in the cave. Even when his Main Body trained, it was only while accompanying Hinata at the abandoned Training Grounds.

He was absolutely certain that Hiruzen Sarutobi had spied on him with Crystal Ball Telepathy.

Over the past two years, Izayoi had fought Sasuke Uchiha once every week or two.

He did not believe that the unstructured sparring matches between himself and Sasuke Uchiha had failed to draw Hiruzen Sarutobi's attention.

After all, before Itachi Uchiha left the Hidden Leaf Village, he had first reported to him, then gone to threaten Danzo Shimura.

If he had not been worried about the Byakugan being discovered, Izayoi would have been unable to resist activating it to check whether Anbu were monitoring the area.

Having his Shadow Clones train all this time, Izayoi had long since controlled the amount of chakra they used, keeping the fatigue feedback within acceptable limits.

After Hanabi finished her glutinous rice balls, Izayoi took her around to play some more, giving her Shoulder Rides as he used the Body Flicker Technique, climbed trees, and walked on water.

Although Hanabi had yet to begin training, she had watched Hinata and Neji Hyuga fight, and had also watched Hinata train and spar with Izayoi. Just like in the original story, she had developed the desire to become someone as gentle and strong as her sister.

Thus, aside from being a little greedy when it came to food, Hanabi did not enjoy playing with children her own age. She preferred having Izayoi take her leaping across rooftops and walls, experiencing the thrill of a "Roller Coaster."

Once she reached the age to extract Chakra and began training, she would definitely become even clingier.

"Nii-chan, goodbye."

"Bye-bye."

After playing with Hanabi until dusk, Izayoi finally smiled and waved goodbye to his clingy Little Sister-in-Law.

Then, rather than going home, he went to the market to buy some ingredients before using the Body Flicker Technique to head for the vast, deserted Uchiha Clan Estate, where Sasuke Uchiha was the only one left.

"You're here."

Sasuke Uchiha, who had been training in the courtyard, looked at Izayoi carrying two bags with fighting spirit written all over his face.

"Let's eat first. We can fight afterward, and take a break while we're at it," Izayoi said with a smile.

"Fine."

Sasuke Uchiha did not refuse.

After night fell, the two ate Hot Pot on the engawa.

Late at night, two small figures darted through the clan estate, shooting into a forest like arrows.

Bang bang bang...

Whoosh whoosh whoosh...

The sounds of impacts, heavy objects hitting the ground, and thrown weapons slicing through the air rang continuously through the nighttime forest.

Boom—

Before long, an explosion rang out, and crimson flames blossomed.

However, the flames were quickly extinguished.

Half an hour later, the two small figures emerged from the forest.

Under the moonlight, Izayoi and Sasuke Uchiha presented a stark contrast.

Izayoi's clothes were neat and spotless.

Sasuke Uchiha, on the other hand, was dressed in tattered clothes, his body covered in burn marks.

Even the exposed skin still bore faint scars.

Yet despite his exhaustion, the young man's eyes gleamed brightly, showing that he had gained quite a lot.

"I won again."

Izayoi looked at Sasuke Uchiha and smiled. "As agreed, I'm going to take a look at your family's Jutsu Library."

"Go ahead. There's only a few things in there anyway," Sasuke Uchiha said indifferently.

After the Uchiha Clan was wiped out, the bodies of its members had been buried by the village.

In exchange, all the scrolls had been confiscated.

Even the inheritance left in the house consisted of only a few low-level Release Technique scrolls.

Sasuke Uchiha had asked the Third Hokage about it. The village had not touched his family's high-level ninjutsu scrolls; they had probably been taken away by Itachi Uchiha.

Sasuke Uchiha did not care much about the village taking his clan's scrolls.

Because the Third Hokage had promised him that once he became a ninja and grew strong enough to take over the Uchiha Clan, he could apply to the village to reclaim the land deed and ninjutsu scrolls.

Right now, he did not yet have the strength to safeguard those things.

Izayoi knew that Hiruzen Sarutobi had been telling the truth.

Aside from secret techniques such as Izanagi and Izanami, the Uchiha Clan's ninjutsu scrolls truly contained nothing worth coveting.

Compared to a powerful Uchiha combatant, such things were simply not worth being greedy for.

Just like the inheritance left behind by Izayoi's parents.

However, Sasuke Uchiha's family Jutsu Library was still very useful to Izayoi.

His mastery of Shape Transformation was extremely high, but his Nature Transformation was practically nonexistent.

Training in the Five Elements Release could improve his Nature Transformation.

If he wanted to perfect the Super Hurricane Combination Sphere, Izayoi had to master all five Nature Transformations and make them strong enough to merge with the Super Hurricane Combination Sphere.

For Wind Release Nature Transformation, Izayoi could draw upon Naruto Uzumaki from the original story for reference. As for the other four Nature Transformations, he could only gain his own understanding through practicing ninjutsu.

Or, after graduation, he could ask his Guidance Jonin for instruction.

Of course, there was another shortcut that would grant him the highest level of Nature Transformation without any training.

That was... awakening the Rinnegan or the Tenseigan!
