Tailed Beast Chakra Fusion, Base Exposed

"Leader.

Suspicious individuals have been spotted spying near the organization.

We still don't know which side they belong to."

Before the words had even faded, Uchiha Mu's expression darkened.

Without waiting for the others to discuss a response, he moved abruptly. Using Scar of Space to teleport in an instant, he appeared directly above the group of spies.

He did not use his full strength, relying only on refined chakra and the oppressive force of his Sharingan to suppress his opponents.

His strikes were swift and decisive. The battle ended in mere seconds, and he subdued every spy, quickly uncovering their identities.

Once the threats around the perimeter had been dealt with, the base returned to its peaceful order.

The entire "Void" Organization was flourishing, its cohesion growing ever stronger and its strength steadily increasing.

After arranging the organization's various affairs, Uchiha Mu

went into seclusion, devoting all his energy to fusing tailed beast chakra.

Back when he was in the ANBU, he had collected portions of the chakra of One-Tail Shukaku and Three-Tails Isobu.

One-Tail Shukaku's chakra

was violent and domineering, containing immense earth-nature power and tremendous explosive force.

It could easily trigger earthquakes and control sand and stone.

Three-Tails Isobu's chakra, on the other hand, leaned toward water nature.

Heavy and enduring, it possessed extremely powerful defensive capabilities. It could control water currents and exert one hundred percent of its strength in water.

Both types of tailed beast chakra contained boundless power.

If he could successfully fuse them, not only would Uchiha Mu's chakra reserves soar, but he would also gain control over both earth- and water-nature tailed beast power, bringing a qualitative leap in his combat strength.

But he also understood that tailed beast chakra was violent and difficult to control.

Fusing two types of tailed beast chakra with different natures and properties was even harder than reaching the heavens. The slightest mistake could result in backlash from the tailed beast chakra, shattered meridians, and death by explosion.

Throughout history, countless shinobi

had attempted to fuse multiple types of tailed beast chakra, yet all had ultimately failed. They either died from the backlash or were controlled by tailed beast chakra, reduced to mindless monsters.

But Uchiha Mu showed no fear.

He possessed the Eternal Mangekyō Sharingan,

which could forcibly suppress the violent aura of tailed beast chakra.

He possessed the time-reversal ability of the Domain of Time. Even if an error arose during the fusion process, he could rewind time in time and correct it.

These were the foundations of his confidence in fusing tailed beast chakra.

The base's secret chamber was pitch-black, with only a faint chakra glow emanating from Uchiha Mu's body.

He sat cross-legged with his eyes closed, his hands forming seals. Chakra slowly surged around him, forming a massive chakra vortex that enveloped him.

Then, his fingertips shifted slightly, and two entirely different streams of chakra silently emerged from his body.

One was earth-yellow chakra, violent and domineering, radiating a dense earth-nature aura. It was One-Tail Shukaku's chakra. The other was pale-blue chakra, heavy and enduring, radiating a dense water-nature aura. It was Three-Tails Isobu's chakra.

The moment the two streams of chakra appeared, they repelled one another and crashed toward each other with piercing roars. Even the walls of the secret chamber trembled slightly, as though they might collapse at any moment.

Uchiha Mu frowned faintly and slowly opened his eyes. The Eternal Mangekyō Sharingan activated instantly, patterns swirling within his scarlet pupils as they radiated cold, overwhelming pressure.

"Quiet down!"

He shouted softly, and the Sharingan's power erupted at full force. A powerful spiritual force instantly enveloped the two streams of tailed beast chakra, forcibly suppressing their violent auras and preventing them from colliding.

Under the Sharingan's suppression, the two streams of tailed beast chakra gradually calmed down, though they still stirred slightly, trying to break free of the Sharingan's restraint.

Uchiha Mu did not relax in the slightest. Using his own chakra as a medium, he slowly injected it into the two streams of tailed beast chakra, drawing them together bit by bit as he attempted to fuse them.

The fusion process was excruciating.

Though the two streams of tailed beast chakra were suppressed by the Sharingan, they remained violent.

They collided and tore through Uchiha Mu's meridians as though they intended to rip them apart.

The agonizing pain made Uchiha Mu's entire body tremble. Cold sweat slid down his forehead, soaking his clothes, while his face turned pale as paper.

Under the impact of the two streams of tailed beast chakra, his meridians

had already developed tiny cracks, and his chakra began to fall into disorder. If this continued, his meridians would sooner or later rupture completely.

Yet he never gave up.

He gritted his teeth, enduring the intense pain through sheer willpower. At the same time, he controlled the Sharingan to continuously suppress the violent auras of the two streams of tailed beast chakra, using his own chakra to gradually harmonize their properties and correct deviations in the fusion.

Whenever cracks appeared in his meridians, whenever his chakra became disordered, he activated the Domain of Time and rewound time by three seconds, returning to the instant the fusion had gone wrong and starting again.

Once, twice, three times...

He did not know how many times he had rewound time or how much pain he had endured. Blood even seeped from the corner of his mouth.

But his gaze remained firm, without the slightest wavering.

He knew that if he endured just a little longer, if he could successfully fuse these two streams of tailed beast chakra, his strength would undergo a qualitative leap. He would be able to protect the "Void" Organization better,

fight the Akatsuki Organization better, and take another step closer to his goal of rebuilding the Uchiha Clan.

He did not know how much time passed. Perhaps a day, perhaps two, perhaps three...

Suddenly, a gate of light opened in his mind.

The two tailed beasts became entwined as one, looking down at Uchiha Mu from above.

Neither side spoke. They merely gazed at each other in silence.

A powerful chakra aura suddenly erupted within the secret chamber. It far surpassed anything from before, heavy and violent as it elevated the powers of both earth and water nature.

It swept through the entire secret chamber and even spread throughout the whole base.

Uchiha Mu slowly opened his eyes. A flash of golden light passed through his scarlet Sharingan.

Chakra surged around him like tides. Earth-yellow and pale-blue chakra intertwined, forming a new and even more immense chakra that coiled around his body.

He slowly rose to his feet and moved his body. The intense pain from before

had completely vanished, replaced by an unprecedented feeling of ease. The chakra within him was full and condensed, while his meridians had become even tougher under the nourishment of tailed beast chakra.

"Success."

He spoke softly, his voice carrying a trace of relief and joy.

He could clearly feel that his chakra reserves had directly doubled, far surpassing those of an ordinary peak Kage-level shinobi. Even against a Super Kage-level expert, he could easily suppress them.

At the same time, his level had reached the limit of Kage level. He was only one step away from Super Kage level.
