Kabuto's Mission

"By sealing the Nine-Tails' container, made of White Zetsu material, inside Kushina Uzumaki's body, while maintaining a wisp of Nine-Tails Chakra output, and combining this with the power of Yin–Yang Release, we were barely able to keep this 'trauma' to her life force in a balanced state..."

The laboratory was built on the side of the attic closest to the mountain, and it was also the largest part of the entire attic. Some of the more secretive experiments were even hidden deep within the mountain.

In the laboratory, Kushina Uzumaki's body lay quietly on the research table, with countless cables connected to her body. Bright light illuminated her body in every detail, but only faint breaths came out of her nostrils, making her seem like a living dead.

Various data flashed across the screen in front of Kato Osamu, but his brows furrowed more and more. Encountering Shinigami was something he had never experienced before, which made him feel even more urgent.

To see the whole leopard from a single spot, both Black Zetsu and the Shinigami are beings created using Yin–Yang Release, and the Tailed Beasts are the same.

A person's strength is reflected in every technique they use. If they can eliminate, or even fully understand, the way that damage is caused, then they will understand the gap between themselves and that being.

He hoped to glean some insight into the mastery of Yin–Yang Release from the damage caused by this Yin–Yang Release, but he was currently completely clueless.

"It seems a bit too early now..."

With a soft sigh, Kato Osamu conjured countless rune chains in his hand, which slowly climbed up Kushina Uzumaki's body, completely sealing this special 'experimental subject' away. Perhaps only when Yin–Yang Release reaches a higher level will he have the opportunity to glimpse the mysteries of this 'trauma'.

"Knock knock..."

"Master Kato..."

Kabuto appeared in the laboratory. After cleaning up the dishes with Rin, he couldn't wait to come into the laboratory. His gaze fell on Kushina Uzumaki, and he frowned slightly.

"What exactly happened to this test subject...?"

Kato Osamu turned to look at Kabuto, seemingly deep in thought. After a moment of contemplation, she slowly spoke, saying that some things were hardly secrets.

"She was originally the wife of the Fourth Hokage, named Kushina Uzumaki. The Uzumaki Clan is naturally blessed with strong physiques; you should have sensed that through the activity of her cells..."

Kushina Uzumaki

Kabuto's eyes widened suddenly as he looked at Kushina Uzumaki's figure, which seemed completely different from before.

He never imagined that the woman lying so calmly on the lab table was actually the wife of the Fourth Hokage. His understanding of her was still vaguely limited to that of a war orphan— Konoha, Sand Shinobi, Kazekage, Hokage —these people and events were lofty figures he could never reach.

Unexpectedly, the Fourth Hokage's wife is now lying right in front of him...

"Lord Kato... could it be...?"

Kabuto's throat bobbed, as if he were thinking of the Konoha 'Nine-Tails Rebellion' that had shocked the entire Shinobi World a few days ago. Although Konoha had classified the details of the incident as top secret, some information had still spread Shinobi World...

Especially the death of the Fourth Hokage...

"It's probably as you think..."

Kato Osamu smiled slightly, saying nothing more, seemingly unconcerned by Kabuto's shocked gaze. Instead, he took out another scroll from his pocket and handed it to Kabuto.

"This 'experimental subject' is no longer needed for the time being. I will seal her away and entrust her with other tasks..."

"Yes..., Lord Kato!"

A brighter light seemed to burst forth in Kabuto's eyes, and his gaze towards Kato Osamu now seemed to carry a hint of admiration.

"This scroll contains a 'Hashirama Cells,' a pair of Sharingan from the Uchiha Clan, a piece of flesh and blood Hyuga the Hyuga clan, and a piece of Kushina Uzumaki's muscle tissue..."

"What you need to do is very simple... compare the genetic material of these materials to determine if there is any possibility of homology..."

Kabuto's eyes held a hint of disbelief. "Lord Kato... you suspect...?"

"Yes, you guessed right, these families may have blood ties..."

Kato Osamu's voice lowered a bit. He realized that there was no need or possibility to hide these things, and perhaps because he rarely had anyone to talk to about these matters, he couldn't help but say a little more.

"A long time ago, when I first came into contact with Hashirama Cells, I was limited by a special energy they possessed and was unable to conduct deeper research. But later I discovered that the Sharingan can, to some extent, suppress this special energy in Hashirama Cells..."

"Even the original rejection reaction to the foreign body will be greatly reduced as a result..."

"And so I began to have doubts..."

"Later, I met someone in Kusagakure who gave me a sudden, almost magical inspiration..."

"This person transplanted the Sharingan from the Uchiha Clan, but the first transplant failed. After all, if transplants could be performed successfully so easily, the Sharingan would already be everywhere in the Shinobi World..."

"However, with the help of the Uzumaki Bloodline, this person's second transplant was successful..."

"I can't remember his name anymore, but this incident remains vivid in his memory..."

"White Zetsu Cells, you should have seen them before. These cells can save an Uchiha Clan who is nearly dead and fuse perfectly with them. And the most amazing thing is that White Zetsu Cells are almost identical to Hashirama Cells, except that they lack that special energy..."

"It's absolutely impossible that there isn't a deeper connection between these three bloodlines..."

Kabuto seemed to be processing Kato Osamu's words. He didn't quite understand why the information he heard in those few short minutes was more valuable than everything else in his entire life.

"Then... what about the Hyuga Clan?"

"This is another guess... Just do as I say for now..."

Kato Osamu didn't explain anything further. If the first step of his thinking was wrong, then there was no point in mentioning the second step...

"The difficulty isn't too high, it just might take a lot of time..."

"Lord Kato! I will definitely finish it as soon as possible!"

"No need to rush..."

Thinking of Hashirama Cells, Kato Osamu couldn't help but think of the Senjutsu of Ryūchi Cave. Natural Energy is a special kind of energy. According to the Snake Sage, it was an energy that existed even before Chakra appeared on this Shinobi Continent. All Three Great Sage Lands have methods for cultivating this energy. Or rather, it is precisely because of this that the Three Great Sage Lands were able to become the Three Great Sage Lands.

"Looks like I'll have to go to Ryūchi Cave..."

"Let 'Zabuza to return..."

The Kusagakure is currently nominally led by Zabuza, but in reality, it's just a rabble. He's heading to Ryūchi Cave, and he probably won't be back for a while. There are some things that still need to be prepared...
