Chakra Solidification

Konoha

Hokage Building

On the rooftop of the Hokage Building, after Naraku finished dealing with the Root matter and making proper arrangements for Shisui and Itachi, he began to contemplate his own situation.

Natural Energy, nearly eight years of liquefied Chakra, has long filled my dantian, but it still cannot be compressed and condensed into a solid; it is always just a little bit short.

After activating the Cursed Seal, the absorption of Natural Energy was rapid, and the liquefied Chakra had filled the dantian. However, this liquefied Chakra also seemed to be inexplicably dissipating.

Naraku's condition had persisted for two years. Naraku understood that there was no shortcut to this kind of training that plundered Natural Energy; only arduous practice would suffice.

He had always thought that he hadn't mastered the skills enough to solidify his power, but after two years of this, Naraku realized that it might not be that his training was lacking, but rather that he was missing something.

"Chakra dissipating... why is that?"

The reason for the failure of Chakra solidification has been troubling Naraku for a long time. After Danzo's death, Naraku became more relaxed and recently focused on his training.

Naraku thought for a moment, then walked to the center of the Hokage Building rooftop, sat cross-legged, placed his hands on his knees, and decided to compress his Chakra once more.

The three black Tomoe on the back of Uchiha Nara's neck emitted a magma-like light, which quickly spread throughout Naraku's entire body.

After Naraku emitted a magma-like glow, the light began to fade, Naraku's skin turned somewhat grayish-black. This grayish-black color lasted for about two seconds before his skin color changed again, returning to its original fair complexion.

After this transformation, Naraku exuded a powerful aura, which was caused by the condensation of a massive amount of Chakra.

Within Naraku's dantian, the blue Chakra cluster, upon closer inspection, resembled stagnant liquid water. The Chakra liquid seemed to receive some command and began to slowly rotate.

Naraku his eyes tightly, controlling the compression of Chakra within his body, while simultaneously absorbing Natural Energy through the Cursed Seal and injecting it with new Natural Energy.

"Still this feeling? Why...?"

No matter how much Chakra was injected, Chakra showed no signs of solidifying. The liquid clumped together, slowly rotating, neither tightened nor compressed.

"I really don't believe it!"

The repeated failures over the past few months left Naraku. A surge of impulse arose in his heart, and he clasped his hands together in a hand Hand Seals, forcefully controlling and compressing the Chakra liquid.

The more Naraku compressed it, the more the previously imperceptible Chakra dissipation became visible, with a large amount of Chakra dissipating and returning to nature.

"So it really is Chakra leakage! In that case, I won't let you leak it!"

Naraku had only vaguely sensed that his Chakra seemed to be dissipating, but this breakthrough in compression confirmed Naraku suspicions.

Naraku immediately formed hand Hand Seals; Naraku a master of Fuinjutsu, he instantly had a solution.

"The Yin Seal is complete!"

Naraku formed a total of 128 hand seals. The Yin Fuinjutsu is extremely complex to form, and once formed, one will benefit from it for life.

With Naraku's soft shout, black patterns appeared all over his body, seemingly following the same path as his meridians. Under Naraku's control, the black patterns converged on his lower abdomen, forming a pale purple rhomboid mark.

The lower abdomen, which had originally been filled with chakra, seemed to have undergone some changes; the dissipated Chakra could no longer escape. Furthermore, due to the sealing and compression of the Yin Fuinjutsu, the Chakra fluid mass began to shrink.

Sweat beaded on Naraku's forehead as he sensed changes within his body. This training was showing initial success, something that had never happened before.

"So tired! Is this Chakra even mine...?"

The liquid Chakra in Naraku's dantian was the essence of Naraku entire body. Under the intense pressure, Naraku felt as if he could no longer control this powerful Chakra, and even the power to manipulate and compress it slowed down slightly.

Now that things had come to this, Naraku could not give up halfway. The Yin Seal: Release, and powerful Chakra surged through his body once again, causing the black patterns that had disappeared before to reappear.

At the same time, Naraku's God Cursed Seal frantically stimulated his body's potential and absorbed Natural Energy.

With the infusion of multiple forces, the previously dormant Chakra compression started again, and the Chakra liquid in the dantian began to slowly rotate once more, shrinking in size with each rotation.

About half an hour later, Naraku in sweat, and the fist-sized ball of Chakra liquid in his dantian had been compressed to the size of a steel ball, seemingly reaching its limit.

"Success or failure hinges on this!"

Naraku mobilized all the Chakra within the Yin Seal in his chest, combined with the absorbed Natural Energy, and frantically suppressed his body's potential, compressing Chakra ball the size of a marble.

The Chakra ball, the size of a marble, started spinning a little faster, its size decreasing as it spun. Eventually, it condensed into Chakra ball the size of a mung bean.

As the Chakra ball took shape, dark clouds filled the sky, and darkness gradually fell.

"It's done? Hahahaha!"

Naraku's Chakra ball was compressed to its limit, turning into a solid, pea-sized ball of Chakra, radiating an aura comparable to that of Tailed Beast.

Sweating profusely, Uchiha Nara realized he had successfully broken through and couldn't help but burst into hearty laughter in joy.

Boom!

The once clear sky darkened, as if it were about to rain. Accompanied by a deafening clap of thunder, Naraku finally noticed the situation in the sky.

"This is?"

Naraku felt a sense of crisis, a sense of being locked in by the gaze of a terrifying creature, and couldn't help but swallow hard.

"Why does this feel like a heavenly tribulation? This is the Hokage Building, we can't be struck down here!"

Naraku had some guesses about the dark clouds. He formed a hand Hand Seals with his right hand, disappeared, and arrived on a hill in the Naka River.

The Naka River is a beautiful place, and Naraku often comes here. He even carved the Flying Thunder God Mark on a Daishi.

Just as Naraku teleported here, the dark clouds in the sky moved rapidly from Konoha towards this location, and their size increased considerably.

"Is this really a heavenly tribulation? Isn't this the Shinobi World? What's going on?!"

Naraku watched the dark clouds in the sky chasing after him, somewhat speechless.

Lightning flashed across the sky, as if it had been gathering power for a long time, and a dazzling bolt of lightning struck Naraku directly.

Naraku had just achieved energy solidification and his life had been sublimated. He was originally eager to try and withstand the power.

However, due to the inexplicable sense of crisis in his heart, Naraku ultimately did not try to withstand the attack or use Ninjutsu. Instead, he simply activated his Chakra, transforming the solidified Chakra into Chakra shield and placing it in front of him.

Boom!

The ultimate Chakra shield was shattered by the lightning, which struck Naraku, causing Naraku a slight tingling sensation, but not enough to be unbearable.

Having experienced Naraku, I have a general idea of what to expect.

Boom!

Before Naraku rest, a second bolt of lightning struck down.

"Uchiha Flame Formation!"

Naraku hand Hand Seals, creating a semi-circular protective shield Naraku. This time, it was infused with elemental properties, unlike before when it was simply Chakra.

"Thank goodness."

The protective shield was shattered, but it neutralized the lightning.

Boom!

Naraku the Uchiha Flame Formation once more, a semi-circular red light flashed, Naraku again.

"Not good!"

The third bolt of lightning cleaved through the protective shield, its momentum still strong as it struck Naraku.

In the critical moment, a black skeleton materialized in front of Naraku, blocking the lightning that had been partially neutralized by the fire array, and the skeleton was shattered in the process.

"It's finally over..."

Naraku a sigh of relief.

The sky grew even darker, with lightning flashing through the dark clouds, which seemed to be baring their teeth in a rage.

Boom!

An even thicker bolt of blue lightning struck Naraku from above.

The hill beside the Naka River was shattered by lightning, and this small hill, which had been in Konoha for more than fifty years, disappeared forever.

"Ahem, I remember Zensui and Inabi said before, 'Chop three times...'"

Amidst the rubble, Naraku coughed twice, barely Susanoo form in a moment of crisis, recalling the words of Inabi Zensui.

Rumble! Rumble! Rumble!

Lightning flashed across the sky, the thunder was deafening, and the sky grew even darker.

Naraku kept a close eye on the dark clouds in the sky. A dazzling light Flash Cut within the clouds, and an increasingly thick bolt of lightning struck down.

"Susanoo!"

Naraku's Chakra surged, his eyes flashing red, and a black giant in full armor enveloped him from the upper body, his right hand Naraku a sharp sword that pierced straight towards the lightning.

The black longsword instantly melted away, and the heavily armored black giant also collapsed directly. Fortunately, it neutralized most of the lightning's power. Naraku only paralyzed by the attack, but he was not completely powerless to resist.

"This is the fifth one, could there be more?"

Naraku gazed at the darkening sky and the suffocating pressure, swallowed hard, and guessed that there was more to come.

"Ninja Art: Creation Rebirth!"

Naraku immediately activated a forbidden medical technique, clearing the paralysis and restoring all his injuries.

"Susanoo! Perfect Form!"

Before the lightning could strike, Naraku bloodshot, and he activated his Ninjutsu. This time, the heavily armored giant grew legs, standing tall and reaching hundreds of meters in height.

As tall as the Green Mountain in the forests of the Land of Fire not far away, the people of Konoha could all notice the black giant not far from the village.

The dark clouds in the sky seemed to be enraged, and a bolt of lightning several times thicker than the previous one struck down.

The towering black giant, before the thunder, was like a mouse and a big cat, engulfed by the terrifying white light of the thunder.

Lightning struck the ground, cracking the earth. The water level of the nearby Naka River dropped by half during the lightning, evaporated directly.

After the lightning subsided, in the crater, Uchiha Nara's figure solidified, his right eye turning grayish-white.

"Is this a case of them determined to kill me?"

Naraku's left eye pulsed with power, while his grayish-white right eye regained its eerie red color. The joy of his previously solidified Chakra was long gone; he had consumed most of his Chakra during the breakthrough and had only just stabilized his state.

He was struck by lightning six more times in a row, Chakra was almost depleted. Naraku didn't even know why he was being struck. If it happened a few more times, he would probably be in real trouble.

Naraku's Dōjutsu and Ninjutsu require Chakra to activate; his eye power is almost equivalent to Yin Release Chakra. Without Chakra, even the strongest techniques are useless.

Fortunately, after the Six Paths of lightning struck, the dark clouds in the sky dispersed, the sky cleared, and rays of light shone on Naraku.

Naraku looked up at the sky, a look of relief at surviving a disaster on his face, and wiped his forehead.

Under the glow of the seven-colored clouds, Naraku comfortable all over, his Chakra began to recover, and the solid Chakra ball the size of a mung bean in his dantian seemed to have undergone some inexplicable changes.

Naraku sat cross-legged, placed his hands on his knees, and enjoyed the nourishing glow of the sunset while introspecting within his body.

"I see. With the Yin Seal added, the absorbed Natural Energy no longer dissipates. It's a pity that the original Fuinjutsu Chakra in my chest is completely depleted. Is this Chakra ball the size of a mung bean called Golden Core?"

"Although the Cursed Seal is not the best way to absorb Natural Energy, it is better than nothing. By absorbing Natural Energy, combining it with one's own energy, and compressing it to the extreme, one has finally reached the Golden Core realm."

"Cursed Seal, compression, Yin Seal —this is truly a Shinobi World technique now. It should be given a name; let's call it the Uchiha Profound Art..."
