NARUTO: SECOND GOD OF SHINOBI

---

Hiruzen Sarutobi stood on the rugged training grounds of Hokage Mountain, the evening sun casting a warm golden glow over Konoha.

Five hours had passed since he began his ambitious task of creating new jutsu, and beads of sweat traced their way down his brow, evidence of the intense concentration he had poured into his work.

He glanced at the scrolls scattered around him, each one filled with intricate details of his newly crafted techniques.

With a sense of accomplishment, he thought, "Now, it's time to start on the S-rank Rasengan series."

He inhaled deeply, feeling the familiar rush of chakra coursing through his body. As he prepared to create the first S-rank jutsu, his mind raced with possibilities.

The Wind Release Rasengan was his target, a jutsu that relied on integrating the fierce nature of wind with the stability of chakra.

Hiruzen made the necessary preparations, his hands moving fluidly, almost instinctively.

The Rasengan began to swirl into existence, vibrant hues of blue and white merging as he infused it with wind chakra.

He felt the power thrumming at his fingertips, a wild force that he needed to tame.

As the wind chakra surged, Hiruzen grimaced.

The gusts brushed harshly against his skin, and he realized that controlling this level of wind was not without consequence.

"Tekkai!" he grunted, hardening his muscles, but even that did little to quell the pressure. The wind lashed at him, tugging at his robes and slicing through the air.

"It's too powerful," he thought, frustration bubbling beneath his composed exterior.

He paused, strategizing. "I need a containment ring to stabilize its energy."

With deft fingers, Hiruzen quickly crafted a ring of chakra, blending simple chakra with wind energy.

As the containment ring formed around the Rasengan, he felt a sense of relief.

The wild winds calmed, becoming manageable under his careful guidance. 

"Now we're talking," he said, a grin spreading across his face. He could already envision the destructive potential of this jutsu. 

He launched the Wind Rasengan toward a nearby rock hill, the air crackling as the energy propelled it forward. 

Boooooooommmm!

The explosion shook the ground, sending fragments of rock flying in all directions.

Hiruzen's heart raced as the wind chakra sliced through the hill, creating a devastating shockwave that radiated outward, obliterating everything in its path.

The range of destruction astounded him, and he couldn't suppress a chuckle of exhilaration.

"I'll call this jutsu 'Wind Release: Rasengan,'" he declared, noting the details in a scroll with a flourish.

Pride swelled within him as he sealed the jutsu, feeling the weight of its potential resting in his hands.

With the first S-rank jutsu under his belt, he felt a renewed sense of energy.

"Now for the Fire Release Rasengan," he said, determination shining in his eyes. 

Hiruzen began forming another Rasengan, this time infusing it with vibrant flames. The heat radiated from the swirling sphere as he combined fire chakra with his own.

The Rasengan glowed a fierce red and white, crackling with raw power.

He knew he needed to contain its explosive energy, just as he had with the wind variant.

He prepared the containment rings again, this time ensuring that they were strong enough to handle the intense heat.

With a confident thrust, he launched the Fire Rasengan at the same hill. 

Boooooooommmm!

The explosion was monumental, flames engulfing the area and incinerating everything within a radius of 150 meters.

The ground melted beneath the force of the blast, leaving behind a smoldering crater.

Hiruzen stood in awe, watching the fire dance in the air, leaving nothing but devastation in its wake.

"Fire truly lives up to its reputation for destruction," he remarked, marveling at the power he wielded.

He quickly jotted down the details, sealing the new jutsu into his scroll with a sense of accomplishment.

Next came the Lightning Release Rasengan. Hiruzen's pulse quickened as he envisioned the raw, penetrating force of lightning.

He constructed a denser Rasengan, picturing a thick stone hill that would serve as his testing ground.

The air crackled around him as he infused the jutsu with lightning chakra, the energy sizzling at his fingertips.

With a swift throw, he unleashed the Lightning Rasengan. 

Crack! Boooooooommmm!

The hill disintegrated before his eyes, the Rasengan tearing through it as if it were made of paper.

Hiruzen's jaw dropped, marveling at the sheer power of the lightning-infused attack.

A pit was left in its wake, deeper than he had anticipated. 

"Impressive penetration," he nodded, recording the jutsu with a satisfied smile.

Hiruzen's focus sharpened as he prepared to create the Earth Release Rasengan.

He visualized a heavier, denser orb, channeling yellow and brown chakra as he shaped it.

The weight felt substantial in his hands, a testament to the power he intended to unleash.

As he hurled the Earth Rasengan at a newly formed hill, the ground beneath him trembled.

Upon impact, the earth shook violently, and the area around the Rasengan pressed down as if gravity itself had intensified.

A deep pit formed, and Hiruzen could feel the raw power emanating from the jutsu.

"This is the raw power of earth," he murmured in awe, taking meticulous notes for the scroll.

Moving on to the Water Release Rasengan, Hiruzen carefully constructed a swirling orb of water chakra.

The Rasengan glimmered, its outer layer resembling a ring of cascading waves.

This time, he aimed for a combination of cutting and penetrating capabilities, blending the strengths of wind and lightning.

He threw the Water Rasengan with precision.

Whoooooooosh! Boooooooommmm!

It sliced through the hill with incredible accuracy, creating a pit that left a 10-meter deep cavity in the ground. 

"This may be the most versatile jutsu yet," he noted, impressed. 

Finally, Hiruzen turned his attention to the Yin Release Rasengan.

He infused the Rasengan with a swirling black chakra, creating an orb that danced with shadow. 

When it struck the hill, the destruction was on a whole new level.

The energy rippled outward, extending over a 300-meter radius, completely annihilating everything in its path. 

"If someone were caught in this, they'd face death at the hands of their own spirit," Hiruzen explained, the seriousness of the jutsu weighing heavily on him.

The Yang Release Rasengan followed, its effect targeting the physical body directly.

As he formed it, he could feel the power thrumming beneath his fingertips.

When he threw it, it left a massive area of devastation, rivaling the Yin release in strength.

"These two are particularly dangerous," he said, marking them as among the most potent jutsu in his arsenal. 

After countless hours of hard work and unwavering focus, Hiruzen finally sat down, his energy waning yet his spirit soaring.

He had successfully created a total of 17 Rasengan jutsu, including 14 elemental variations and three pure chakra arts, with eight categorized as S-rank and nine as A-rank.

Exhausted but exhilarated, he leaned back, gathering his thoughts.

"My chakra reserves are too low for the large-scale ninjutsu I need," he mused, contemplating his next move. 

A new idea sparked in his mind, illuminating his thoughts. "I should create a seal that compresses and increases chakra, then gradually releases it over time." 

Determined, he set to work on this new project, fully engaged in the intricate details of seal creation.

As he sketched the symbols, he could almost feel the potential flowing through his veins. 

"This could enhance my abilities exponentially," he thought, his resolve strengthening with each stroke of his brush. 

Hours passed as he immersed himself in his task.

As he worked, the sun dipped lower in the sky, painting the horizon in shades of orange and purple.

Hiruzen paused for a moment, allowing himself to reflect on the journey he had taken to reach this point. 

"Each jutsu I create is a step forward, to strengthen the village development," he murmured, a smile touching his lips.

With the final strokes of his brush, he completed the seals.

Hiruzen stood, stretching his arms overhead, invigorated by the night air.
