Black Zetsu forced himself to calm down...
The entire Konoha Village, along with the reanimated Senju Hashirama and Uzumaki Mito, became targets for Aomi's Dojutsu absorption, and were already wasted...
The good news is that the audacious Aomi actually dared to pull Kaguya out from the moon, which naturally attracted the attention of the Six Paths Sage.
"That guy, no matter how strong he is, can't be stronger than the Six Paths Sage who has been operating in the Pure Land for thousands of years, unless he is able to obtain his mother's power... Uchiha Aomi will at least have to remain isolated underwater for a while, unable to move freely in the Ninja World..."
"Otherwise, as soon as he reappears, the Six Paths Sage will assume that mother has escaped, and will impose a strong counterattack!" Black Zetsu analyzed in his heart, feeling some enlightenment, keeping up with Aomi's thought process.
That's right!
Aomi had anticipated this step, which is why he had Senju Tobirama resurrected to provoke the people of Konoha Village, as well as stir Uchiha Madara's thoughts...
To provide him with a constant source of power to combat Kaguya while he was temporarily unable to move in the deep sea!
In Black Zetsu's view, the Six Paths Sage was also being schemed against by Aomi.
The Six Paths Sage hiding in the Pure Land had long been guessed by Black Zetsu, who had been searching for Asura and Indra Chakra for a millennium...
Only Black Zetsu chose to hide, but Aomi pretended to seal Kaguya to make him hesitate, bolder and reckless!
If it weren't for the Six Paths Sage being in the Pure Land...
Black Zetsu truly feared Aomi's unreasonable Dojutsu might even bind Kaguya's rebellious offspring, which would indeed be troublesome!
The bad news is, although Kaguya isn't in a complete state, she is not suppressed by Aomi, but with her intellect, being alone with Aomi always makes Black Zetsu worry that Kaguya might be talked into a daze...
"In any case, whatever Uchiha Aomi wants to do, I must oppose it!"
Black Zetsu took a deep breath and thought to himself: "Since he wants to quietly be alone with mother Kaguya underwater, then I must find a way to disrupt his progress!"
"He wants Senju Tobirama to draw the attention of Uchiha Izuna and Uchiha Madara now... then I must prevent him from succeeding! The White Zetsu Network is under my control..."
"I must let the unaffected Uchiha Madara and Uchiha Izuna silently enhance their strength!"
"This way, even if they encounter Senju Tobirama later, these two will have enough Dojutsu power to perceive or resist Aomi's Dojutsu. Even if emotions arise, they will merely be bound by him, not significantly empowering him!"
Informed openly about his "Dojutsu" by Aomi, Black Zetsu racked his brain trying to counter Aomi with reverse thinking.
The idea was truly good, and the approach was correct...
The only error was that, whether Uchiha Madara, Uchiha Izuna, or the Six Paths Sage, were all already bound by Aomi.
If Aomi knew Black Zetsu's thoughts, perhaps he would give him a thumbs up, but he would also smile and ask it— "Zetsu, when did you get the illusion that I haven't bound their minds?"
To gain the upper hand, Black Zetsu focused his gaze on Obito.
Not knowing Aomi's true identity, Uchiha Madara and Uchiha Izuna, thinking they can defeat Aomi through their own means...
It's truly difficult!
Meanwhile, Black Zetsu's public identity as Uchiha Madara's "Yin Yang Release creation" fundamentally prevents communication with them.
However, only Uchiha Madara might still attempt some means...
But with the presence of Uchiha Izuna, Black Zetsu, noticing this Uchiha's ambiguous attitude towards the Eye of the Moon Plan, worriedly feared exposing more flaws, possibly bringing Kaguya into the mix.
So, the one and only communication line is with Uchiha Obito!
"If I merge with Obito, making him my Jinchuriki..."
Excitement flashed in Black Zetsu's eyes: "I can actively protect his mind and try to offset or weaken Uchiha Aomi's Dojutsu tied to him..."
"I can also pass the power mother left me onto Obito, letting him grow stronger before Uchiha Aomi notices!"
Black Zetsu had some foundation to work on.
It could control Uchiha Obito who, albeit in a weakened state, still had Ten-tails' power within...
And could stand behind Uchiha Madara, stabbing him through the heart with a claw, urging Kaguya's descent...
In daily battles, Black Zetsu wasn't effective, but if acting as an inner strategist, applying its key singular-use power for nurturing Obito's chakra and Dojutsu, it was highly suitable!
Thus...
The issue before it was how to explain its identity to Uchiha Obito?
Thinking was very optimistic!
However, each time Black Zetsu considered meeting Uchiha Obito in the form of a pitcher plant or as a little black figure...
Its heart was filled with reluctance, even a hint of fear!
If Uchiha Obito liked it because of the body named Uchiha Rin, then Black Zetsu would soon become the laughingstock of the Ninja World for centuries!
What a mockery it would be...
But that said, if Uchiha Obito, even facing this form, still treated it like he treated Uchiha Rin before...
Wouldn't it mean that Uchiha Obito truly liked its soul?
Even though it had no soul.
Such gain and loss emotions continuously stimulated Black Zetsu's heart...
"That guy, his position in Obito's heart might be second only to mine..."
