Fire Style Concept

The relationship between the ninja clans and the Kage was like that between shareholders and professional managers.

A ninja clan council involving the interests of powerful clans was equivalent to a shareholders' meeting; a jonin meeting involving votes on critical affairs was similar to a corporate executive meeting.

Rather than the birth of a regime, Konoha's founding was more like the establishment of a military conglomerate.

During the reigns of Konoha's First and Second Hokage, the Senju Clan and Uchiha Clan—the two major "controlling shareholders" behind Konoha's founding—handled practical affairs. The Senju Clan was by far the strongest at the time and held absolute control, so it firmly occupied the Hokage position for two generations, effectively serving as both chairman and general manager.

During the First Great Ninja War, the Senju Clan donned armor and charged into battle, taking part in every conflict of the war. The once-mighty number one clan in the Ninja World had been drained dry by endless attrition, leaving very few young and middle-aged Senju ninja and severely weakening its strength. Meanwhile, the Uchiha Clan had been kept suppressed within the village. Aside from Kagami Uchiha's branch, which was allowed to fight, most members spent their youth grinding away in the Konoha Military Police Force. Yet because of this, the clan preserved its strength.

Third Hokage Sarutobi Hiruzen's appointment had been both the Second Hokage's final wish and the result of compromise among the ninja clans.

—The fully preserved Uchiha Clan was simply too strong. Especially without the Senju Clan to restrain it, if an Uchiha became Hokage, Konoha would practically take on the shape of the Uchiha.

Uchiha Tokimitsu had risen from a young ninja clansman to the commander of a border force not only because his clan had entrusted its members to his command, but also because the village higher-ups had All Along been painstakingly seeking to weaken the powerful clans.

However, the Hokage and his advisers probably had not expected that the Northwest Border Defense Force, which had faced the most critical situation and the greatest disparity in strength, would, after being reinforced by Uchiha Clan ninja, sweep away the unstable factors in the Land of Grass in one push. It had even taken the initiative to enter the Land of Earth and suppress Iwagakure until it could only remain behind closed doors.

It was like a professional manager who had intended to send a shareholder's foolish son to take over a subsidiary on the verge of bankruptcy, hoping the shareholder's family would lose money and face humiliation—only for that young master to display astonishing prowess, turn losses into profits in one stroke, and leave the group's management humiliated yet helpless.

After withdrawing from the front lines and returning to the Garrison Camp, Uchiha Tokimitsu dumped all the miscellaneous affairs onto Staff Officer Nara Kohei and began considering his ninjutsu training.

Ever since childhood, Uchiha Tokimitsu had received Elder Setsuna's instruction. His training had followed the standard Uchiha ninja curriculum, and as a ninja powerhouse with a thousand-year legacy, the Uchiha Clan naturally possessed every kind of training material. Moreover, as the Radical Faction's next-generation Heir, nearly all of the Uchiha Clan's secret ninjutsu manuals and data had been open to him. Combined with his extraordinary Spiritual Power and the comprehension granted by the wisdom of his previous life, his progress in ninjutsu training had been astonishing, far surpassing his peers.

The Uchiha Clan's attainments in ninjutsu were undeniably profound, especially its vast collection of Fire Style secret manuals. But that also posed a problem: if Uchiha Tokimitsu followed the Uchiha Clan's training path completely, then at best, his achievements would likely only reach the level of Uchiha Madara's younger brother, Uchiha Izuna—because he lacked Indra's Chakra enhancement.

Uchiha Tokimitsu's greatest advantage was his absolute control over Chakra and his abnormally immense Spiritual Power. Naturally, his disadvantage was that his physical constitution was not much different from that of ordinary Uchiha clan members. Since Chakra was refined from a combination of physical energy and Spiritual Energy, his relatively ordinary physique limited the amount of Chakra he possessed.

His research direction was also clear: to devise a ninjutsu system based on Fire Style.

Fire Style generally manifested as high-temperature, explosive, high-damage attacks. Uchiha Tokimitsu's idea, however, was to grant Fire Style the properties of refinement and sublimation.

Like the immortal cultivators and qi practitioners in the cultivation chronicles he had read in his previous life, he would use Samadhi True Fire as the tempering flame for his life-bound Golden Core and continuously elevate himself.

"First, I need a Golden Core..."

Uchiha Tokimitsu's idea was naturally just wild, unconstrained speculation, but that was not much of a problem. Fire Style was the Uchiha's greatest specialty, after all. Even if he messed something up, he could fix it.

There had been countless different accounts of the Golden Core in the various materials and biographies of his previous life. In the age of declining Dharma, all related cultivation materials had long been lost, but they shared one common feature: the Golden Core was one of the products of dual cultivation of life and nature.

Gold referred to an indestructible nature, while core referred to a perfected round form. Hence the name Golden Core.

Indestructible perfection was precisely Uchiha Tokimitsu's dream in this life.

Uchiha Tokimitsu gradually recalled the ninjutsu data he had read in the past. The benefit of powerful Spiritual Power was an extremely strong memory; as long as he had examined something carefully, he could generally remember it through serious recollection.

"The Golden Core is the result of dual cultivation of life and nature..."

Then accordingly, for Uchiha Tokimitsu, perhaps it should be Fire Style Chakra plus Yin Release Chakra—Fire Style Chakra represented the union of physical energy and Spiritual Energy, while Yin Release Chakra represented the ultimate sublimation of Spiritual Power, which was "life."

He carefully circulated the Chakra within his body.

"Qi flows through the dantian..."

But where was the dantian?

That question left Uchiha Tokimitsu dumbfounded.

He had often heard and read terms like dantian, Ren and Du, but figuring out how to locate them was a major problem.

Forget it. No need to dwell on it. In his previous life's five-element theory, the heart belonged to fire, so he would first gather Chakra at the Heart Position.

As the Chakra gathered, Uchiha Tokimitsu clearly felt his heartbeat accelerate and his blood surge, as though he had been injected with adrenaline. Then his body temperature began rising rapidly.

He hurriedly refined Yin Release Chakra from his head and directed it to the Heart Position. Like a coolant, the Yin Release Chakra, under the control of his will, forcibly suppressed the volatile nature caused by Fire Style's inherent instability.

Carefully sensing the gradually stabilizing Fire Style Chakra, Uchiha Tokimitsu slowly adjusted the ratio between Fire Style and Yin Release Chakra.

Under the effect of the two Chakra attributes, he clearly felt the originally incomparably violent Fire Style Chakra gradually become tame, beginning to display the properties he wanted in accordance with the concept in his mind.

In the end, the ratio of Fire Style Chakra to Yin Release Chakra stabilized at roughly two to one.

"Thump, thump..."

His heartbeat gradually grew louder and faster, yet his body temperature did not rise along with it. Soon, the Chakra circulation gradually stabilized, and his heartbeat slowly returned to a steady rhythm.

Within Uchiha Tokimitsu's inner perception, red Fire Style Chakra and black Yin Release Chakra rotated and merged in the form of Yin-Yang Fish, fusing to produce a purple energy.

"The union of two Chakra attributes... Is this the power of a Golden Core, or a Kekkei Genkai...?"

Uchiha Tokimitsu muttered inwardly. Even he was not quite sure.

Kekkei Genkai had two forms. The common one in the Ninja World was the fusion of two Chakra nature transformations to produce a new release, such as Scorch Release, which was Fire Style plus Wind Style, and Ice Style, which was Water Style plus Wind Style. The other was an ability gained when a certain bodily organ differed from that of ordinary people, such as the Uchiha Clan's Sharingan, the Hyuga Clan's Byakugan, and the Kaguya Clan's Shikotsumyaku.

As for the Chakra power produced by combining Yin Release and Fire Style, should it be called "Yin-Fire Style"?

"Yin-Fire Style is a bit of a mouthful. 'Yin Fire' sounds better..."

Uchiha Tokimitsu showed tremendous interest in this new type of Chakra power that had emerged through exploration, completely ignoring whether casually experimenting with Chakra might affect his body.

He then fused Fire Style and Yin Release Chakra in other parts of his body, only to find that the efficiency was always inferior to transforming them at the Heart Position.

Perhaps that had something to do with the properties of the five viscera as well.

But how was this circulation supposed to be maintained?

That stumped Uchiha Tokimitsu.

His current Chakra circulation relied on conscious control while sitting in meditation. The greatest problem was making this Chakra circulation cycle continue on its own.

After all, the newly formed "Yin Fire" Chakra power was still far too weak. He had yet to discover any special effects beyond promoting blood circulation, much less form a concrete technique.

After much thought, combining the ninjutsu data he had read in this life with the messy and varied settings from his previous life, Uchiha Tokimitsu thought of a way to use Sealing Jutsu to maintain the Yin Fire circulation.

That was Sealing Jutsu.

For a truly suitable solution, Tsunade's Yin Seal would have been the best choice. But even the Uchiha Clan could not possibly possess the Sealing Jutsu Secret Techniques of the Senju and Uzumaki clans, so Uchiha Tokimitsu could only search through the Sealing Jutsu data he had read for an applicable technique.

"Four Symbols Seal..."

After recalling it for a while and considering his own circumstances, Uchiha Tokimitsu found a Sealing Jutsu that might be suitable.

The so-called Four Symbols Seal was a sealing formula that formed a closed loop through the circulation of four attributes to seal foreign power.

But Yin Fire was actually the combination of Yin Release and Fire Style.

So he intended to simplify the Four Symbols Seal in order to create a circulation using two Chakra attributes.

After another round of experimentation, Uchiha Tokimitsu worked out a simplified casting method for the Four Symbols Seal.

Since it balanced and circulated two types of Chakra, he would call it the "Yin-Yang Seal."

"Tiger—Dragon—Dog—Tiger..."

Uchiha Tokimitsu slowly formed hand seals while sensing the changes in the Chakra within his body.

"...Boar—Rat—Rooster!"

After Uchiha Tokimitsu's adaptation, the newly created Yin-Yang Seal was completed with a total of seven hand seals.

"Yin Fire Sealing Jutsu: Yin-Yang Seal!"

Finally, he pressed his palms together. Two types of Chakra Energy were refined from within his body and gathered at the Heart Position, then manifested in his palms through his blood vessels.

The Fire Style Chakra gathered in his left hand appeared as a flame, while the Yin Release Chakra gathered in his right hand appeared as a mass of Black Qi. With his palms pressed together, the two manifested Chakras began colliding and merging under the restraint and suppression of Spiritual Power and Sealing Jutsu, eventually becoming a purple sphere of light in his palms.

"Success!"

Uchiha Tokimitsu was extremely excited.

He was very satisfied with the result.

As an ordinary person without a research background, successfully creating a new ninjutsu by combining the wild ideas of his previous life with the ninjutsu data he had read in this one was already quite impressive. Especially since this newly created Sealing Jutsu could form an effective Chakra circulation system—it could not have been more perfect.

After separating his hands, a tomoe formed in each palm. The Fire Style manifestation in his left hand was a red tomoe, while the Yin Release manifestation in his right hand was a black tomoe.

Even with his hands apart, he could still sense some mysterious connection between the Chakra in his palms, maintaining the rotational circulation of the Yin Fire Chakra Yin-Yang Fish at his Heart Position.

And when he pressed his palms together, as long as he gathered Chakra separately in each hand, the inducement of the Yin Fire Chakra in his heart and the gathering of the two Chakra attributes in his hands would naturally cause Yin Fire Chakra to manifest outwardly.

In other words, if Uchiha Tokimitsu could devise techniques based on this Yin Fire power, he could essentially achieve something similar to First Hokage Senju Hashirama's exclusive secret ninjutsu ultimate technique—the Clap-and-Manifest Technique!

Uchiha Tokimitsu took out the bottle of Military Rations Pills from the Ninja tool bag at his waist, opened the cap, and poured them straight into his mouth without even looking, completely disregarding their side effects.

What he most wanted to explore now was the specific application of Yin Fire power, and that required a massive amount of Chakra to support.

Once the Military Rations Pills entered his stomach, their nutrients began producing large amounts of Chakra Energy as they were digested with the aid of Chakra and intestinal movement.

"Clap!"

Uchiha Tokimitsu pressed his palms together, and a mass of purple light slowly burst forth between them.

Under the control of his Spiritual Power, the purple light gradually took the form of flames, while the Chakra no longer dispersed into the outside world under the restraint of his Spiritual Power.

Slowly, the purple flames began spreading from his palms, yet they did not scorch his clothing.

The purple flames passed over his wrists, head, chest, waist, and legs...

In a short while, Uchiha Tokimitsu's entire body was enveloped in purple aura flames.

He casually reached out and touched the ground.

"Sizzle, sizzle, sizzle, sizzle!"

A hole was rapidly burned into the ground, and its edges even took on a glassy appearance.

Uchiha Tokimitsu could not help clicking his tongue in amazement.

He was quite satisfied with this Chakra Energy that had come about through a fortunate accident. At the very least, its destructive power was exceptionally outstanding.

At least based on how it felt to him now, the elemental damage of Yin Fire Chakra was controllable.

If it was merely released outward, it formed an aura around his entire body, causing no harm to the objects on him. He also felt pleasantly warm and extraordinarily comfortable. But if, under the control of his Spiritual Power, he loosened his restraint over the Yin Fire power, it could form a special composite property combining incineration and explosive force.

To melt the sand and gravel in the ground, its instantaneous temperature was probably between 2,000 and 3,000 degrees. That far exceeded the temperature produced by ordinary Fire Style.

Uchiha Tokimitsu was very satisfied with this. From the effect alone, he had already thought of many possible applications—for example, using a method similar to Scorch Release to form fireballs that could burn enemies into Flying Ash in an instant.

"The future is bright, the future is bright..."

At this moment, Uchiha Tokimitsu was grinning from ear to ear, Not at all as composed as he usually was.

Purple aura flames swirled around his body as protection, while two fireballs formed casually and flew beside him. Gods would fall before gods, Buddhas before Buddhas—nothing could stand in his way...

Especially the aura flames covering his whole body, just like a Super Saiyan...

"Super Saiyan!"

Uchiha Tokimitsu jolted, raised his hands to look at the purple aura flames rising and falling around his body, and fell into deep thought.

"Should this state be called Super Uchiha Mode or Yin Fire Chakra Mode...?"
