The Water Release: Super Great Waterfall Technique was a ninjutsu Uzumaki Rin had modified from the original Great Waterfall Technique. He had increased both its impact force and water volume, pushing its power close to the S-rank level.
However, the true purpose of this technique was not raw destruction—it was to create a favorable battlefield, transforming the surroundings into a vast ocean.
Facing such a technique, Sakumo Hatake could only choose to evade. Taking it head-on was simply not an option. His strengths lay in kenjutsu and Lightning Release; when it came to other types of ninjutsu, he might not necessarily surpass Rin.
But neither kenjutsu nor Lightning Release provided powerful defensive techniques.
So he could only dodge.
At the same time, he couldn't help but feel a trace of envy toward Rin's immense chakra reserves. To forcibly create an entire ocean out of nothing—this level of chakra was far beyond what a normal person could possess.
"Rin is amazing…" Kurenai's eyes sparkled with admiration.
"Damn it… is this his true strength?" Asuma was also shocked by the towering waves. He hadn't expected Rin to have been hiding this much power.
They had all attended the Academy together—so why was Rin this strong?
The unwillingness burned in his chest.
At that moment, instructors from nearby training grounds also sensed the sudden surge of chakra and rushed over. Meanwhile, Hiruzen Sarutobi had already begun watching through his crystal ball.
When the waves of the Super Great Waterfall Technique subsided, the entire training ground had turned into an ocean.
Both Rin and Sakumo now stood atop the water's surface.
"If you think changing the battlefield is enough to defeat me, then I can only say you're too naive," Sakumo said calmly. "A qualified shinobi must maintain full combat capability in any environment—just like this."
The moment he finished speaking, he charged toward Rin at incredible speed.
That speed… is it from Lightning Release stimulating his cells?
Rin was startled. Sakumo's speed was almost on par with the Body Flicker Technique.
Slash!
A streak of white light flashed—
Rin's body was cut in half.
But instead of dispersing into smoke, his body turned into a pool of water.
"Uncle White Fang, I know I'm far inferior to you in close combat, so I already left that position. Now the real battle begins… please, take this!"
Rin's voice echoed from another direction. Beside him stood three Shadow Clones.
"Water Release: Water Dragon Bullet Technique!"
"Water Release: Rain Formation!"
"Water Release: Water Continuous Bullets!"
The three clones rapidly formed hand seals, releasing three different Water Release techniques.
The Water Dragon Bullet Technique was a single-target attack, while the Rain Formation and Water Continuous Bullets were wide-area techniques.
All three were signature techniques of Tobirama Senju.
Even the Water Dragon Bullet—normally a B-rank jutsu—had been elevated to A-rank due to Tobirama's improvements, and Rin executed it using Tobirama's original hand seal method learned from the Sealing Scroll.
Facing three A-rank Water Release techniques, even Sakumo felt a headache coming on.
He could dodge the Water Dragon Bullet, but the other two large-scale attacks were impossible to avoid entirely.
So after evading the Water Dragon Bullet with a Body Flicker—
The blade in his hand finally erupted with white chakra light.
Slash! Slash! Slash!
Boom! Boom! Boom!
White arcs flashed through the air as countless water bullets and descending water blasts were cut apart by the chakra-infused White Fang blade.
Apart from scattered droplets splashing onto him, Sakumo remained completely unharmed.
Rin wasn't surprised.
He never believed three techniques alone could defeat a Kage-level opponent—that would be nothing but a fantasy.
So while Sakumo was surrounded by the barrage, Rin quietly threw eight special kunai in all directions.
By the time Sakumo broke free from the large-scale assault and prepared to locate Rin—
He discovered something alarming.
Nine Rins stood around him, forming a perfect circle—
all simultaneously forming hand seals.
Not good!
Sakumo's expression changed instantly.
He could tell at a glance—this next attack would be far more dangerous than anything before.
But by the time he attempted to retreat—
it was already too late.
The nine Rins completed their hand seals and slammed their palms onto the water's surface.
"Water Release: Nine Dragon Vortex Formation!"
Roar!!!
Nine massive water dragons materialized in front of them.
The moment they appeared, they began spiraling in unison, accelerating the vortex's rotation.
At the same time, the nine dragons rose into the sky, dragging massive volumes of water upward.
The water beneath Sakumo's feet began spinning violently.
He had no choice but to move to the very center of the vortex—otherwise, he would be pulled into the swirling current.
Even though he knew the center was just as dangerous…
he had no other option.
By now, the nine water dragons had ascended over a hundred meters into the sky, carrying enormous amounts of water with them.
From miles away, people could clearly see the colossal dragons twisting through the air.
"Will… will Teacher Sakumo be alright?" Kurenai asked anxiously, her pride in Rin's strength mixed with worry.
"I… I don't know… he should be fine… right?" Asuma stammered, his mind completely blank as he stared at the massive water dragons.
Whoosh! Whoosh! Whoosh!
At that moment, instructors and students from other training grounds arrived.
"What's going on? Is there an enemy attack?"
"Who used such a powerful Water Release?"
"Why is Uzumaki Rin here? What happened?"
The crowd was stunned, staring at the nine massive dragons in disbelief.
"Asuma, what happened?" asked Inoichi Yamanaka.
"I-it's Rin… he's fighting Teacher Sakumo… we failed the test, and Rin sent us away before continuing the fight alone," Asuma explained.
"Father…!" Kakashi Hatake exclaimed, completely stunned.
"What?! Uzumaki Rin is fighting White Fang? And… White Fang is inside that?!" Inoichi's face changed drastically. The other Jonin were equally shocked.
This battlefield—
could a newly graduated Academy student really create this while fighting the White Fang?
Wasn't this the level of a clash between two Kage-level experts?
"Yes… Teacher Sakumo is trapped inside… will he be in danger?" Kurenai asked anxiously.
No one could answer.
To say there was no danger would be a lie—the power of this technique was obvious even from the outside.
But to say there was danger…
this was the White Fang of Konoha, a Kage-level powerhouse second only to the Hokage. How could he possibly be harmed by a fresh graduate?
Just as everyone stood there, stunned and uncertain—
Minato Namikaze spoke with a grave expression.
"White Fang-senpai is in danger… and very serious danger."
"Because this… is a secret-level Water Release technique."
