Verification

The ruthless methods shattered every bone in Han's limbs.

An iron chain was used to constrict his mouth.

This stripped Han of his last shred of resistance.

The next step is the final experiment to verify whether Katsuki's theory is correct, so no mistakes are allowed.

"Ninjutsu, Six Pillars Void Realm."

It erected a protective barrier of emerald green light, providing yet another layer of protection.

"... Han, let's take a gamble! Let's see if you'll be the first Jinchuriki to have their Jinchuriki Tailed Beast and survive..."

Black patterns appeared on Han's chest, intricate and mysterious, seemingly containing an unknown order within the chaos. These were multiple seals set up by Katsuki to seal the Five-Tails and Han's Chakra.

In order to carry out the experiment smoothly, it is necessary to remove these unnecessary seals and retain only the original seals.

"Untie!"

With a gentle touch of the finger, the dazzlingly intricate patterns began to twist and move as if alive, slowly dissipating like unraveling silk.

"BOOM!!"

The Five-Tails 'Chakra, which had been suppressed for a long time, suddenly erupted like a volcano awakening.

The vast aura flashed by and disappeared in an instant, not lasting for long.

Because Katsuki took action.

"Ninjutsu, Empty Cup."

His right palm struck out like lightning, landing heavily on Han's chest. In an instant, an invisible binding force spread out, cutting off the channel through which the Five-Tails was about to unleash its power within Han's body, and forcibly distorting the flow of energy. The Tailed Beast Chakra converged towards Han's chest.

A crimson, ominous Chakra light shone, like sparks trapped in an invisible cage. Though unwilling, they were powerless to resist the restraining force. The intense aura was suppressed, and the room returned to normal.

The Five-Tails' wild and untamed power flowed slowly along a fixed path into Katsuki's palm, like flowing into an empty, bottomless pit. No amount of Chakra could fill this unfathomable void.

The Uzumaki Clan's top-tier technology for extracting Tailed Beast.

--Empty Cup.

Empty Cup signifies a cup that can never be filled.

Using itself as a vessel, serving as both the caster and the recipient, it can extract Tailed Beast single-handedly without the need for any third or even fourth party's intervention, while also creating new Jinchuriki. This is the Empty Cup.

Of course, this is a secret Secret Technique that only the Uzumaki Clan can master. It was created by the ancestors of the Uzumaki Clan based on the bloodline and physical characteristics of the Uzumaki Clan. Even if outsiders possess an equally large amount of Chakra, they cannot perform this technique without the sealing properties of the Uzumaki Clan's Chakra.

Han leaned against the cold wall, his eyes glazed over, devoid of any light.

He was completely broken by Katsuki's beating. The mental torture and physical pain caused this tough man to break down completely. Even now, as the Five-Tails is being slowly peeled from his body, he shows no reaction whatsoever.

But--

Katsuki doesn't need his mental response.

His research focused on the fluctuations of the physical body.

"Wow! Has it already begun to decline? That's fast... but it's still within the margin of error..."

A total of twelve Shadow Clone crouched around, constantly monitoring Han's reaction. If it weren't for the limited space inside the Six Pillars Void Realm, this number might have been several times higher.

Before even one-tenth of the Five-Tails' stripping process was complete, Han's body showed signs of decay; cell activity suddenly decreased, and his heart rate began to slow...

As time progressed, the separation of the Five-Tails also accelerated.

Two-tenths... Four-tenths... Five-tenths...

When more than half of the Five-Tails had been removed, Han's life functions once again suffered a major disruption.

The heartbeat remained at a low level and did not decrease further, while the cells in the body seemed to have lost control, abnormally swelling, rupturing cell membranes, and resulting in cell necrosis.

Multiple experiments were conducted over the past three days.

Katsuki twice used the Empty Cup to extract the Five-Tails' Chakra. Each time, he stopped the experiment when he had extracted about seven-tenths of the chakra and fed it back to the Chakra.

Because once the extraction exceeds seven-tenths, the cells in Han's body begin to undergo irreversible necrosis.

"Has necrosis begun?"

"Do it!"

Five-tenths is a threshold.

The Shadow Clone placed their hands on Han's limbs and began to heal his necrotic cells. As long as they did not reach the threshold of seven-tenths, these cells still had the potential to recover.

Katsuki's idea was based on this period of recovery.

While the Jinchuriki's necrotic cells are still within the recovery period, Medical Ninjutsu is used to heal the cells that would otherwise take time to slowly recover as quickly as possible.

Then maintain this state, that is, keep the cell necrosis in a reversible state permanently, so that even if the 70% threshold is exceeded, it will not fall into an irreversible state of cell necrosis.

This is the theory of Jinchuriki healing established by Katsuki.

At first glance, it seems like a very simple theory with nothing special about it, but upon closer examination, it is also impossible to find a direct and compelling reason to refute it.

The simpler the truth, the harder it is to break!

The four Shadow Clone around him each performed their duties, using their physical abilities to heal the necrotic cells in different parts of his body, while the main body cut a wound on its left palm, and drops of blood flowed into Han's mouth.

The necrosis of cells did not suddenly occur in a certain part, but rather, as the power of the Five-Tails, which was both a radiation source and a safety valve, weakened, the cells that were originally forcibly calmed down by the Five-Tails 'Chakra began to go berserk, resulting in an outbreak that spread throughout the entire body.

It can be said that the moment the Tailed Beast is extracted, a large number of cells in the Jinchuriki's body die, which affects vital organs such as the internal organs and brain, and death will follow.

"... We'll soon find out whether our theory will work..."

A Shadow Clone muttered to itself, while the main body of Katsuki was completely focused on casting the Empty Cup, steadily drawing upon the Five-Tails' power...

Up to seven-tenths.

In an instant, seven-tenths of the Five-Tails' Chakra was extracted, and Han's body began to tremble violently. Unfortunately, the bones in his limbs were broken, and apart from writhing in place like a worm, Han could not perform any other movements.

"Keep it up, hang in there!"

"Damn, our Chakra is being used up way too fast! At this rate, we'll be gone in just three minutes."

The Shadow Clone started shouting.

As Han broke through the limit, his body experienced a rapid decline in vital functions. At this point, the extraction of the Tailed Beast was irreversible. Even if the extraction was stopped now, the death of the Jinchuriki could not be stopped.

More than seven- Tailed Beast Chakra was extracted, representing the transfer of the Tailed Beast's main will. The remaining three- Tailed Beast Chakra is like a tree without roots or a source of water; once this portion of Chakra dissipates and is exhausted, the body's decline will be inevitable. Logically speaking...

But this time was different. Katsuki's Shadow Clone spared no expense in using Chakra to heal the cells that were rapidly dying.

What's even more special is that Katsuki used her own blood; the immense life force soothed the cell death and physical collapse caused by the fading of the Tailed Beast Chakra...
