"I will try to turn Ten-Tails' corpse into a weapon."
Kazuki didn't refuse upon hearing this.
The Uchiha Clan's Gunbai was made from the branches of the God Tree, and as long as it wasn't a Six Paths level battle, it could play a huge role. Even in a Six Paths level battle, it might not be unable to participate.
"Oh, right, recently I've gained some new insights, and this is also the path the Sage of Six Paths is currently taking. Compared to Kekkei Mora, this kind of power is more suitable for the Ninja World."
Kazuki thought for a moment, then continued, "At least I feel that learning Six Paths Yin-Yang Power is much easier than Kekkei Mora."
Kazuki believed that Hagoromo would definitely realize this in the future, but he wasn't afraid of Hagoromo overthinking things. Rinnegan's ocular techniques were incredibly diverse, so any new ocular technique appearing was understandable.
Kazuki's ocular techniques were incredibly diverse, so why couldn't a technique that allowed him to observe and learn others' powers appear now?
"This is still too far-fetched for us." Tobirama said with a bitter smile.
He was still in the Edo Tensei state. His resurrection was still a long way off, and even if he were resurrected, he probably wouldn't be able to participate in battles against the Ōtsutsuki, at most only providing support.
Just like in the past battles between Hashirama and Madara, Tobirama couldn't participate directly. Providing support and occasionally disrupting was all he could do, a testament to his confidence in the Flying Thunder God Technique.
However, Tobirama knew that Ōtsutsuki might also be skilled in space-time jutsu, and perhaps even have a superior perception of space than them.
But this was the first method Tobirama had thought of.
While conducting his research, Tobirama also researched Sage Mode.
Hashirama was always researching a universal Sage Mode, so Tobirama naturally wouldn't miss out.
With his Edo Tensei body, he wasn't afraid of being consumed by Natural Energy. Currently, he had learned Sage Mode, but ordinary Sage Mode was a long way from Six Paths Sage Mode.
"Take your time. You can start thinking about resurrection." Kazuki narrowed his eyes.
"If Ōtsutsuki arrive this time, it will be an opportunity for you, as the Rinnegan possesses Rinne Tensei."
"So you want those Ōtsutsuki to resurrect us?" Hashirama became curious.
During this time, he had actually been somewhat idle. He had already researched ordinary Sage Mode, and he didn't have Tobirama's research capabilities. Aside from researching the so-called Six Paths Sage Mode, he had nothing else to do.
But how could Six Paths Sage Mode be researched by a dead person?
He could at most do the preparatory work. As for the follow-up, that would have to wait until he was resurrected.
Even with Madara, Hashirama found it difficult to visit him frequently. After all, at the end of the day, Madara was officially an adversary.
If Fugaku and Black Zetsu on that side noticed, it might affect Madara's plan.
"I have that idea." Kazuki's lips curved into a smile.
Black Zetsu could control Obito to perform Rinne Tensei, so why couldn't he do the same?
As long as he wanted to, not only could Tobirama, Hashirama, and Madara be resurrected, but Kagami and Mito could also be resurrected. Anyway, it would only cost one Ōtsutsuki's death.
Sacrifice others, not oneself.
If Kazuki were to perform Rinne Tensei, he would not die, but he would lose some of his power.
A technique that reverses life and death is not so easy to achieve. It's very difficult to do without paying some price.
Especially for Hashirama and Madara, resurrecting them completely is extraordinarily difficult.
Tobirama said, "I have to say, you are very bold. Before you became Hokage, many of your methods were unconstrained. I don't know whether to say you're ignorant, or that you're skilled and therefore daring, but if there's an opportunity, I wouldn't mind trying."
"Afterward, I will adjust my and big brother's Edo Tensei to their optimal state, and even add some of Madara's power into them. As for Madara's side, you will need to adjust him yourself."
Towards the end, Tobirama actually found it very difficult to say.
They actually had to inject Madara's power into their bodies.
There was no other way. There were only a few Uchiha with the most excellent bloodline that had appeared so far.
Indra and the like, Tobirama couldn't even consider. He didn't know how many years Indra had been dead, and they couldn't find Indra's corpse. Instead, there was one reincarnation of Indra Chakra.
Kazuki was theoretically the most suitable and the strongest, but his power was too immense.
Even if Kazuki had suppressed his power, it was not something he could easily contend with.
Injecting Kazuki's cells might lead to them being directly devoured by his cells. Even diluting with White Zetsu cells wouldn't work.
Instead, Madara's cells were the best choice.
Perhaps because Madara had once transplanted Hashirama's cells, the vitality displayed by his cells was even greater than that of Hashirama's cells. However, his cells could be diluted with White Zetsu cells. In other words, Madara was the best transplant material.
Once upon a time, everyone considered Hashirama's cells a panacea, but Tobirama had to admit that Madara's strategic value was actually superior to Hashirama's, especially for those who wanted to awaken the Sharingan.
Nawaki, Kushina, and others were actually already being injected with Madara's cell solution. It was just that this situation was difficult for Tobirama to accept.
He knew it was the correct choice, but wouldn't their bloodline be contaminated by the Uchiha?
And by Madara, whom he disliked the most.
However, if one were to truly consider it, it seemed that Hashirama's cells were the first to contaminate Madara.
For the future, even Tobirama had no choice but to inject himself with Madara's cell solution.
