The information provided by Ichimaru Gin was very useful.
When Aizen Sousuke parted with Ichimaru Gin, he was still pondering the story Ichimaru Gin had mentioned, that there seemed to be more than one person who had created the Hogyoku in this world.
According to the information Aizen Sousuke knew, Yakushi Kabuto hadn't existed for long, yet he had crossed time and broke through the spiritual boundaries of the Shinigami. Perhaps the so-called White Zetsu Armor played a role in that.
Aizen Sousuke contemplated the derivative Black Zetsu from when he created the Hogyoku, his brows furrowing slightly. Perhaps he could wait for Black Zetsu to complete its mission and return, and then try to see if Black Zetsu, like the Hogyoku, could be integrated into his body...
After all...
Black Zetsu had devoured many souls and Hollows; its spiritual power was quite formidable, and maybe at that time, it could give him a higher foundation.
Black Zetsu was a derivative from his previous failure to create the Hogyoku...
Now he still had a complete and successful Hogyoku within his body.
The power of Black Zetsu and the power of the Hogyoku complemented each other. Coupled with the spiritual power of the Shinigami he possessed inside, it might be another means of breaking limits.
As Aizen Sousuke pondered, he slowly paced into Orochimaru's laboratory, a laboratory even he found somewhat overwhelming.
Orochimaru was still tirelessly researching the upper limits of Hollow power, always attempting to break through the limits of quality via quantity. Just within this laboratory, there was a Vasto Lorde-level Hollow and two Achyukas-level Hollows.
These Hollows, which could rival the Captain of the Shinigami outside, were mere test subjects in Orochimaru's experiments.
"What a rare guest..."
Orochimaru put down his experimental apparatus, took off his gloves, and casually invited Aizen Sousuke to sit down, chuckling as he said, "Hehehe... shouldn't you be researching Hogyoku in your own laboratory at this hour?"
"There's something I want to inquire about, Mr. Orochimaru."
Aizen Sousuke didn't sit down; he simply stood at the door, watching Orochimaru, and softly said, "How much does Mr. Orochimaru actually know about Uehara Naraku?"
"The most gifted Shinigami in the world."
Orochimaru opened his palm, his mouth curling into a sinister smile: "Since he was twelve, I've coveted his body... As long as I can obtain it, I will become the god of all worlds!"
This was no lie!
Back when Orochimaru defected from the Akatsuki, he encountered a pursuit by Uehara Naraku. It was his first humiliating memory, and since then, Orochimaru often paid attention to Uehara Naraku.
Taijutsu, Immortal Technique, Ninjutsu, Genjutsu, Chakra...
Uehara Naraku possessed virtually no weaknesses.
Moreover, Uehara Naraku had experienced another world, where he established the Akatsuki's rule like a god. In that world, Yakushi Kabuto acquired some miraculous abilities and thoroughly surpassed Orochimaru's power.
As for the Bleach World, Uehara Naraku showed no discomfort, and it wasn't long before he exhibited powerful talent, breaking through the limits of the Shinigami.
That kid...
Seemed to have never had limits of power!
Aizen Sousuke didn't know all this; he was just still pondering, and the atmosphere in the laboratory gradually became somewhat heavy.
Until much later.
Aizen Sousuke suddenly raised his head, looked at Orochimaru, and said, "Then... does Mr. Orochimaru know that Naraku's power has already surpassed Uchiha Madara?"
"Hehehe..."
Orochimaru's face showed no surprise; he merely grinned and slowly shook his head, then suddenly nodded, "Wasn't this destined to happen? I did warn you back then..."
"Actually Naraku is hiding his power."
Aizen Sousuke interrupted Orochimaru.
"Hahahahahahahaha!"
But the next moment, Orochimaru suddenly split his mouth wide open, nearly laughing loudly, "How interesting... Aizen...
Do you still think there will be any good people among the Uehara Race? The Uehara Race... are there any naive people? I've long suspected that kid's disguise!"
"Perhaps the naive person is me."
Aizen Sousuke lightly shook his head and continued, "When life and death in the world have no meaning, there will be no boundaries between good and evil either."
"Exactly."
Orochimaru very much agreed with Aizen Sousuke, but he spoke again, "However, you don't have to worry too much... even if that Uehara Naraku kid becomes a god, with the Hogyoku you've obtained, you can evolve to another dimension."
At this point, Orochimaru suddenly smiled and said, "Now that you've obtained the Hogyoku, we can't delay any longer, can we? When can my revenge begin?"
"Very soon."
Aizen Sousuke looked at Orochimaru and softly said, "Please start preparing, Mr. Orochimaru... After the final experiment, be ready for war!"
As the final insurance, the final power boost, Aizen Sousuke wanted to wait for Black Zetsu to return and absorb Black Zetsu into his body.
This world...
Ultimately belongs to the powerful.
While Aizen Sousuke was actively leading war preparations, secretly sending Black Zetsu to try to incite unrest between the Uehara Race and the Quiet Spirit Court, he awaited the final opportune moment.
Fortunately, Black Zetsu brought him some bad news.
Initially, Aizen Sousuke wanted to plan a little longer, but a sudden change forced him to abandon the idea of sitting on the sidelines!
