Just so happens...
In that illusionary world, there was also mention of a Genjutsu called Infinite Tsukuyomi and another Genjutsu called Limited Tsukuyomi, both capable of creating similar world changes.
To be honest...
Orochimaru couldn't quite distinguish them.
However, the ending of the story seemed to have too many flaws.
If Orochimaru were Akihara Kagura, if anyone in the Ninja World were Akihara Kagura, they wouldn't possibly let the Ninja World go, and would definitely plunder all the Chakra.
"Who knows what that guy is thinking..."
Uchiha Sasuke raised his eyebrow slightly and said slowly, "Maybe it's because his power is too great, he doesn't care about that trivial Chakra..."
"Truly arrogant, just like the Uchiha..."
Orochimaru's lips curled into a light smile, as if implying something.
"Sasuke-kun..."
"I'm more curious about something else..."
"Four years ago, on that night of the clan massacre..."
Orochimaru stared intently at Uchiha Sasuke, referring to the truth revealed by the omnipotent Akihara Kagura in the illusion, asking about the truth that Akihara Kagura spoke of.
"What state has your Sharingan reached?"
"Single Tomoe Sharingan."
Uchiha Sasuke didn't lie, he even reached to touch his eye socket, "On that night, it was the first time I awakened the Sharingan..."
It was also...
What Uchiha Sasuke couldn't comprehend.
Yet someone once told him, it was because his Sharingan was too powerful that he only awakened the Single Tomoe Sharingan, instead of gaining more power.
"..."
Orochimaru found the credibility of this memory even lower.
This kid must be joking, right?
His parents and clan were all killed by his own brother, though Uchiha Sasuke's natural talent didn't seem bad, he only awakened the Single Tomoe Sharingan that night?
This kid...
Just how much power did he gain that night?
Such that he even fell into such a powerful Genjutsu and didn't want to wake up?
Orochimaru's thoughts leaned towards the idea that Uchiha Sasuke fell into his own Genjutsu.
Because of the clan massacre incident four years ago, the shock Uchiha Sasuke received was too great, awakening the Indra Chakra, the reincarnation of the Six Paths Sage's eldest son, within his body.
The strength of the Indra Chakra made Uchiha Sasuke fall into his own Genjutsu, thinking he experienced a false world, gaining power from that false world, but the false power was due to the Yin Attribute Chakra's feedback to the real soul...
In the memory after all...
There was indeed Genjutsu that allowed entry into a false world.
Even in the illusion, those surviving Uchiha, including Uchiha Sasuke, gained power through Akihara Kagura's Limited Tsukuyomi Genjutsu.
All evidence indicated...
Uchiha Sasuke had fallen into his own Genjutsu.
Yet this kid still believed he experienced a real world, wanting to return to that false world, gaining power yet falling into madness...
Orochimaru genuinely didn't think Uchiha Sasuke was lying.
After all...
The dark-haired boy seemed like a madman unable to accept reality, could a twelve-year-old intentionally create the impression that he's a madman to others?
"Alright."
"Let's discuss the important matter now..."
"How can I return to that world?"
Uchiha Sasuke's expression was seriously intense, as if he was discussing a proper matter, "Do I have to live until reaching the point where I entered this false world?"
"There may be another way."
Orochimaru squinted his eyes, offering another suggestion, "But I need massive financial support, Sasuke-kun needs to cooperate fully with me to execute another plan..."
"Hehehehe..."
Orochimaru's lips curved up, he slyly proposed his initiative, "We need to find an opportunity soon to get rid of that old man; the old man is always watching everything in Konoha, it's hard to escape his surveillance for whatever we plan to do secretly..."
After all...
Killing the Third Hokage...
Was also an important goal for Orochimaru in coming to Konoha!
Orochimaru wanted to kill his teacher, Third Hokage Sarutobi Hiruzen, to prove he was on the right path, and also wanted his ally Shimura Danzo to regain power, providing more funding for his experiments.
At that time, after the Uchiha massacre event, Shimura Danzo was stripped of his Hokage Assistant position and his Root organization by Sarutobi Hiruzen due to his involvement in the event, causing Danzo to only work in the shadows over the years, assisting Orochimaru less and less...
But now...
Orochimaru also wanted to help Danzo gain power first!
Moreover...
There was now an additional important reason!
Once Shimura Danzo had power, he could force or capture Uchiha Sasuke from within Konoha, and Orochimaru would have the chance to take over Uchiha Sasuke's body!
Of course,
now wanting to kill the Third Hokage clearly couldn't bypass Uchiha Sasuke.
Uchiha Sasuke, with his immense strength, would certainly interfere with his plans!
"..."
Uchiha Sasuke tapped his fingers against his arm.
Whether it was the Third Hokage's handling of the relationship between the Uchiha Clan and Konoha, or Shimura Danzo's passive role in the Uchiha massacre incident, Uchiha Sasuke, with a mature mind, felt no special fondness for the Third Hokage.
Honestly...
Choosing not to intervene...
This was already fair enough in Uchiha Sasuke's heart.
