The Sage's Appearance

Konoha

Hokage Building

On the rooftop of the Hokage Building at night, Naraku cross-legged, holding a blue Cursed Seal liquid that he had successfully prepared by replacing Jugo's bodily fluids with Hero Water, while four Anbu stood beside him carrying lanterns for illumination.

"The Cursed Seal, when imbued with a treasure like the Hero Water, can enhance the absorption of Natural Energy without causing physical mutations."

Unlocking the human body's thresholds: powerful ninjas Jonin develop their body's thresholds differently from ordinary people.

Whether it's the Strength of a Hundred Technique, the Eight Inner Gates, or some other unique Taijutsu, they are all methods to unlock the potential threshold of the human body. There is absolutely no need to force it open in such a brutal and dangerous way as Cursed Seal.

"As long as the Cursed Seal is stable enough and can absorb Natural Energy, then it is the most promising Ninjutsu."

Naraku held a vessel filled with blue liquid in front of him, examining it closely.

Naraku's Cursed Seal differs somewhat from Orochimaru's. The Heaven and Earth Cursed Seal serves as a reference, while Orochimaru's ordinary Cursed Seal is the primary focus of his research.

A high survival rate is essential for significantly expanding and enhancing the strength of subordinates. Implanting one hundred and having fifty die is meaningless to Naraku.

No one in the Uchiha Clan relies on increasing their physical strength to enhance their combat power. They only need to absorb Natural Energy and release their Chakra by unlocking their potential through the Cursed Seal.

After Naraku's improvement, the ordinary Cursed Seal possesses the stability of the Heaven and Earth Cursed Seal, while also eliminating the mutation process of state two.

Compared to Orochimaru's Cursed Seal, each has its advantages. After all, growing an extra pair of hands or wings, once one becomes familiar with the new limbs, can greatly enhance combat power. It's just that these mutations occurred in Naraku himself, Naraku somewhat unhappy about.

Naraku pondered for a moment, then without further hesitation, he took the needle in his right hand, inserted it into the back of his neck, and injected the blue liquid.

"Natural Energy, come!"

Naraku roared inwardly. As the liquid was injected, Naraku Chakra surged. Three black Tomoe appeared an inch below his spine at the back of his neck. A gentle breeze stirred on the top floor of the Hokage Building as Naraku's Chakra fluctuated.

"My body should have already reached the potential and physical threshold that the Cursed Seal can unleash, so the danger to me is limited."

About ten minutes later, Naraku's Chakra stabilized. The injection of the Cursed Seal, as Naraku had anticipated, carried limited risks and posed no threat to Naraku, who was extremely familiar with the human body.

After all, Naraku's Medical Ninjutsu and Taijutsu were exceptionally superb.

"Next up is Cursed Seal Level 2..."

Naraku's palm rippled, and a wooden barrel appeared in the field. Naraku's palm rippled again, and a small medicine jar appeared.

"You four, prepare to use the Four Black Mist Formation and the Black Sealing Method Seal!"

"Yes, sir!" X4

The four Anbu replied in unison.

Naraku took out five talismans, wrote the Black Sealing Method Seal on them, and handed them to Uchiha Tekka, a member of the Anbu codenamed Tetsu, before sitting down in the wooden barrel.

"I've made so many 'Awakening Heart Pill,' and I still don't know what they taste like..."

Naraku poured out the Awakening Heart Pill, glanced at it, and swallowed it in one gulp. About five seconds later, Naraku felt extremely uncomfortable all over his body, as if he was about to suffocate.

"No wonder they were all choking themselves, looking like they were in terrible pain."

Naraku recalled the appearance of his previous experimental subjects and now he understood the feeling.

Naraku did not resist the drug's effects; instead, he cooperated by closing his eyes, relaxing his mind, and falling into a deep sleep.

"Four Black Mist Formation!"

The four Anbu had cooperated many times in Qingcha Town before and were very familiar with this scene. Soon, the black mist emanating from their palms condensed above the wooden barrel.

Four Anbu pressed their hands down, filling the wooden barrel with black mist and concealing Naraku's figure.

"Black Sealing Method Seal!"

Uchiha Tekka threw five Sealing Tag into the wooden barrel. As if under control, the Sealing Tag symmetrically adhered to the edge of the barrel in a five-pointed pattern.

Naraku's consciousness was in a deep sleep. In his hazy state, he felt his body was light, as if he were floating in the sky. In the sky, countless strange mists surged into Naraku's body.

"Um!?"

After an unknown amount of time, Naraku from the wooden barrel. His Chakra fluctuated slightly, five Sealing Tag fell, and then a burst of black energy surged from above the barrel.

After a while, the black mist gradually thinned out, revealing Naraku's figure.

"Is this Natural Energy?"

Naraku's skin was grayish-black, and his long, curly black hair had grown even longer, trailing on the ground. A reddish-yellow light emanated from Naraku's body, and after the light faded, his skin returned to its normal color.

Naraku felt the already terrifying surge of Chakra within his body increase even further, and it gained a strange rhythm.

The Cursed Seal Level 2, which is based on the Hero Water, appears outwardly normal, except for a yellow-red, magma-like glow emanating from an inch below Naraku's cervical spine at the back of his neck.

Naraku back down in the barrel, sensing the changes in his Chakra and his body.

"You guys go home after get off work!"

Naraku seemed to realize something and gave instructions to his four Anbu guards.

"Hi!" X4

The four Anbu guards wanted to watch a little longer, but the Lord Hokage had spoken, so they had no choice but to retreat and go home.

If Naraku hadn't been worried that using Shadow Clone would disperse his Chakra and affect his entry into Cursed Seal state, he would never have let anyone notice this scene.

After the guards left, Naraku formed a hand seal.

"Drink!"

Naraku a soft shout, and the air above the mansion Naraku forth as if in a riot, converging into his body.

Visible Chakra surged from Naraku's body. This Chakra, which could be seen externally, returned to Naraku's body under Naraku control and eventually condensed in his lower abdomen, specifically in the dantian area.

The ultimate Chakra, like a thick fog, was drawn by Naraku to his lower abdomen, specifically his dantian. After Naraku's powerful compression, it was as if rain was falling from Naraku's dantian; the Chakra, at its most intense, transformed into raindrops, which pattered down into his dantian.

After the raindrops filled one-fifth of Naraku's dantian, Naraku's Chakra disappeared, seemingly all of it gathering in his lower abdomen.

"In the Shinobi World, no matter how powerful a ninja is, they all combine physical energy and spiritual energy to form Chakra."

Chakra is like air; no matter how excellent one's bloodline, it cannot be changed. Even with my vast Chakra Uchiha Nara is only as dense as fog when refined.

Now, with the addition of Natural Energy, coupled with my unparalleled Chakra reserves, I have liquefied my Chakra in one fell swoop. This should be the first time in the history of the Shinobi World that I have achieved this!

Naraku sensed the Chakra in his dantian, and a wide grin spread across his face, overjoyed.

Naraku's original Chakra reserves were already considered to be at their peak in the Shinobi World.

Naraku's immense Chakra, combined with the enhanced spiritual energy from the Mangekyō Sharingan, brought his spiritual energy to its peak, which then nourished his body.

Then, through the Chimera Technique, he devoured various outstanding ninjas who had merged, especially Uzumaki Akayuki, who was devoured by Naraku. Uzumaki Akayuki was someone whose physical energy had reached its peak, and he used this energy to nourish his spiritual energy.

The convergence and condensation of various forces made Naraku's Chakra reserves arguably the limit that humans could achieve in the Shinobi World.

Most ninjas 'Chakra is just a wisp of gas on their bodies, sparse and mediocre.

Naraku's Chakra was as thick as mist. Compared to other ninjas observed by the Sharingan, a single drop of Naraku's liquefied Chakra was equivalent to the entire Chakra of Jonin.

In the Shinobi World, there are powerful Ninjutsu and various secret techniques to enhance strength, but there is no technique that can unify the body's strength.

There are techniques without limits; the bizarre and powerful nature of Ninjutsu means that there is nothing Ninjutsu cannot do, only things that cannot be imagined.

And yet, none of these powerful Ninjutsu are methods for Chakra, enhancing, or Chakra.

Having lived two lives, Naraku had a different view on the use of energy than the natives; he believed that Natural Energy was an infinite form of energy.

As long as Naraku can absorb it and contain it, then he can achieve the sublimation of life.

"This method of absorbing Natural Energy was improved through Orochimaru's Cursed Seal and aided by the rare and precious Hero Water. It can be considered a rudimentary form of a technique, but it's not entirely accurate..."

Sensing the immense energy of the liquid Chakra within his body, Naraku couldn't help but feel joy.

"Gasic energy, liquefy it, liquefy the energy, then solidify it. Liquefaction is successful! Consume the remaining Hero Water, and the energy should soon be solidified into a pill!"

Naraku pondered for a moment, then thought of the Three Sacred Lands, and couldn't help but slightly curl his lip.

"A snake, a frog, Katsuyu —three little demons who have lived for a thousand years dare to be so arrogant, calling themselves immortals. We will capture them sooner or later!"

Naraku closed his eyes, stretched his hands towards the sky with his fingers spread, and looked on with a look of ecstasy as if he were asking for something.

"The immortal of the Shinobi World, I alone..."

On the top floor of the Hokage Building, two scarlet lights shone like the eyes of a ferocious beast opening.
