Hakushi is trying every possible means to strip away the dark parts from Zero-tailed Chakra.
The extracted 'darkness' can be used to make a special poison that induces mental fatigue in enemies.
It can be said that the Chakra and darkness from Zero-tailed are rare treasures in the Ninja Realm.
Even a tiny bit of waste would be a pity to Hakushi.
"Mr. Hakushi, the data has been recalculated, and the utilization rate seems to be a few percentage points higher than before."
Nohara Rin, dressed in a white coat and wearing a white mask, sat in front of the computer, compiling the data and reporting the latest experimental data to Hakushi.
"It seems that the technology for a fully grown-tailed beast is still far off."
The Chakra of Tailed Beasts is hard to utilize.
The negative energy contained within is even more terrifying than that found in Zero-tailed, making it difficult to remove.
If this power were to directly affect a human body, it would cause the user to lose sanity and inflict an indelible trauma on the body and spirit.
In the Ninja Realm, currently, only the Eight-tailed Jinchuriki Killer Bee of Hidden Cloud Village, the foster brother of the Fourth Raikage, can perfectly utilize Tailed Beast power.
Hakushi greatly admires such figures, who can resolve the resentment within Tailed Beast Chakra and merge seamlessly with the beast; it's not something accomplished with a simple word.
It's because Eight-tailed Jinchuriki Killer Bee possesses an extraordinarily broad-minded persona, allowing him to coexist peacefully with the Tailed Beast, gaining its trust and recognition.
This method is leagues superior to the violent control exerted by Wood Style and Sharingan over Tailed Beasts.
As far as Hakushi knows, despite the many years that have passed in the Ninja Realm, only Killer Bee has truly understood the boundless heart of Tailed Beasts.
Figures like the First Hokage and Uchiha Madara did not achieve this; their utilization of Tailed Beast power always carried a selfish side.
Hakushi considers himself equally selfish.
He's not a person with the open-mindedness of Killer Bee, but it doesn't prevent him from appreciating figures like Killer Bee.
If he could have a face-to-face conversation, it might greatly enhance his research into Tailed Beasts.
"Unfortunately, the Seven-tailed within me harbors a large prejudice against me and has always been unwilling to communicate."
Rin smiled helplessly.
After returning from Shikkotsu Forest, she has been living in the research institute of the First Military Region in the Land of Demons, helping both in its hospital and research facilities.
Obito spent half a year barely mastering Natural Energy before returning from Shikkotsu Forest to serve as an ordinary patrol guard with the Uchiha clan members in the military region.
"Humans selfishly define Tailed Beasts as uncontrollable forces of danger, labeling them as symbols of 'calamity' and 'evil' while ignoring their own will, imposing various restrictions on their freedom; this itself reflects our arrogance. Ninjas who can become perfect Jinchuriki are one in a million. It's enough to just strive in that direction."
Hakushi comforted Rin with a smile.
Rin is only about thirteen to fourteen years old now, and her life dealing with Tailed Beasts is still long, so there's no need to rush.
"Should the research continue?"
Rin asked.
"Of course. I sympathize with the Tailed Beasts from the perspective of an impartial third party, criticizing humanity. In reality, I am part of humanity. I notice the dominance of the strong over the weak; similarly, the benefits Tailed Beasts bring to humanity is something I value. The will of the Tailed Beasts does not need much consideration. Perhaps if the Seven-tailed within you heard my statements, it would be sneering dismissively right now."
Hakushi suddenly said with a laugh.
"Indeed, its mood is not very good right now."
Rin chuckled bitterly.
Hakushi's manner of mocking... no, mocking Tailed Beasts, would surely sow resentment and dissatisfaction among them.
This dissatisfaction clearly infiltrated Rin's body, allowing her to feel the heavy resentment of Tailed Beasts towards humanity.
This is an unbreakable deadlock between Tailed Beasts and humans for eternity.
The Tailed Beast has its stance; humans have theirs.
Stripping away all notions of righteousness and evil, the essence is thus.
"Alright, I'll leave this to you for now, Rin. I need to go out for a while."
Hakushi took off his white gloves, threw them into the trash can, and prepared to leave the laboratory.
It was time to visit the shrine, according to the date set over a year ago, to see his newly born foster daughter.
