Looking back at Black Zetsu's various actions, why was he so cautious?
To put it bluntly...
Was it not because he lacked confidence in his'storytelling' abilities? Thus, he could only exploit Uchiha Madara's arrogance and conceit, slowly guiding Madara toward his goal step by step, only daring to truly reveal himself when Madara was old and frail.
His goal was to give Madara no time to think!
What was he afraid of?
Was it not the fear that Uchiha Madara would calm down and slowly contemplate the 'Infinite Tsukuyomi'?
According to his original plan, he would wait until the nine Tailed Beasts were collected, then have Uchiha Madara brought back via Edo Tensei, and then use the contingency in Nagato's Rinnegan to cast the Outer Path — Samsara of Heavenly Life Technique to fully resurrect Uchiha Madara.
At that time...
The resurrected Uchiha Madara could directly become the Ten-Tails Jinchuriki. In his excitement, Madara wouldn't have the mind to think so much and would use the Infinite Tsukuyomi in a short time. Then, Black Zetsu would take the opportunity to launch a sneak attack on Uchiha Madara, allowing 'Mother' to reappear using Madara's body.
But, what about now?
The sudden rise of that fellow Uchiha Jin had completely wrecked his schemes.
With a great enemy like Konoha present, the Nine-Tailed could not be captured at all!
He had previously thought about delaying as much as possible, thinking at worst they'd wait until the other Tailed Beasts were collected before letting the Edo Tensei Madara deal with the enemy Konoha. The problem was, they couldn't wait for that day anymore!
Uchiha Jin was far too troublesome!
It would still take some time for the Three-Tails and Six-Tails to resurrect. He feared that before these two Tailed Beasts could return, Uchiha Jin would have already led the Allied Shinobi Forces to completely wipe out the Akatsuki Organization.
Therefore, sigh!
After a helpless sigh, Black Zetsu, limited by his lack of wits, still chose to leave this decision to the seemingly 'reliable' Nagato.
There was no other way!
He had to pick the tallest among the dwarves.
Although Nagato himself was incredibly foolish, at the very least, within the Akatsuki Organization, Nagato was considered the one with the best brain!
As for whether to bring Madara back via Edo Tensei, he would listen to what Nagato had to say first.
Even though Nagato was not of the same mind as him, at least before the Tailed Beasts were collected, they were all grasshoppers on the same string—fairly good allies for the current stage.
Meanwhile, on the other side...
Obito was quite displeased with Black Zetsu's proposal.
Perhaps he was indeed very grateful to Uchiha Madara at the beginning, but after so many years of growth, no matter how stupid he was, he had sensed the cursed seal Madara had planted in his body and understood that he was merely a pawn for Uchiha Madara.
Of course...
He also had great trust in the Infinite Tsukuyomi, yet he did not want Madara to be the one to cast it. He believed he was fully capable of replacing Uchiha Madara.
If Uchiha Madara were truly brought back via Edo Tensei, he really had no confidence that he could control him!
However...
Obito did not show his displeasure.
He wasn't sure if Black Zetsu, as Madara's shadow, held control over the cursed seal in his body, so he naturally looked toward Nagato nearby.
In response...
After thinking carefully for a moment, Nagato spoke slowly in a calm tone:'Since our plans are barely being completed, I feel there is no need to use Edo Tensei on Uchiha Madara.'
'Konoha's strength is indeed terrifying, but as long as they cannot assemble the Allied Shinobi Forces, then in the face of the current chaotic Ninja World, the Akatsuki Organization can easily hide. Even Konoha shouldn't dream of finding us.'
'So, let's wait!'
'Wait for the Three-Tails and Six-Tails to resurrect. Capture these two Tailed Beasts first, then think about how to capture the Nine-Tailed.'
'In the meantime, what our Akatsuki Organization needs to do is truly hide ourselves within the Ninja World; we must not easily let Konoha discover our hiding place.'
'Therefore, during this period, we must not only hide but also appear from time to time to assassinate Ninjas from Other Ninja Villages, keeping the entire Ninja World in chaos as much as possible.'
'Besides that, we must save Konan!'
'No matter what the price, I must rescue Konan. I need both of you to help me with your full effort in this regard.'
'I'm sure you both understand how important Konan is to me.'
'Any objections?'
After pondering for a long time, Nagato finally gave his thoughts.
Yes!
Having truly witnessed the power of Senju Hashirama, Nagato was naturally more wary than ever of that 'Asura of the Ninja World' who could rival Senju Hashirama.
Unless truly forced into a corner, he did not want to bring Madara back via Edo Tensei!
Nagato couldn't manage plans that were too far off.
What he could do was try to keep the Akatsuki Organization from clashing with Konoha before the Three-Tails and Six-Tails resurrected—to put it bluntly, to stall for as much time as possible.
Only after capturing those two Tailed Beasts would be the day to truly go head-to-head with Konoha.
As for whether to bring Madara back via Edo Tensei, that could wait until the actual war began.
Of course, before that...
He had to rescue Konan, and for that, he didn't hesitate to pressure Black Zetsu and Obito a bit.
There was no other choice!
After truly seeing Konoha's current strength, he had already abandoned the arrogant title of 'God.' So even though he vaguely knew Obito and Black Zetsu had their own agendas, he still chose to force the two to help him rescue his Konan.
Although his words were subtle, he believed the two would surely understand.
And indeed, they did.
Both Black Zetsu and Obito were quite displeased in their hearts.
They didn't care at all about Konan's life or death. As long as they could keep Nagato's Rinnegan, even the rest of the Akatsuki Organization could be sacrificed.
Especially since Konan's strength was only so-so; the help she could provide for Akatsuki's future plans was actually quite limited.
Since Konan had already been captured by Konoha, in their eyes, they might as well consider her dead.
However, it was a pity.
They also knew the friendship between Konan and Nagato, so the word 'refuse' simply couldn't be spoken. After all, now was not the time to fall out with Nagato.
Thus, after pondering for a bit, Obito slowly nodded: 'No problem, I will help you.'
To be honest...
After hearing Nagato's previous words, he truly felt a sense of relief in his heart.
If Madara were really brought back via Edo Tensei, he would definitely be restricted.
Considering he had Kamui in hand and could leave even if he couldn't save Konan, he agreed despite his displeasure.
But after agreeing, he added another sentence: 'Nagato, you must also do me a favor. It is time for my eye to be retrieved.'
'Fine, no problem!' Nagato nodded.
Now that he knew Obito's identity, he naturally knew that Obito's other eye was in the hands of Konoha's Kakashi.
Meanwhile, on the other side...
Black Zetsu also spoke: 'I will provide intelligence support!'
