Rinne Rebirth.
Obito was no stranger to this ninjutsu, which only the Rinnegan could perform.
In Madara Uchiha's original plan, Nagato was to use this technique to resurrect Madara Uchiha so he could personally carry out the Eye of the Moon Plan.
But neither Nagato nor Obito had any intention of bringing Madara Uchiha back into the world.
Being powerful while alive was one thing, but expecting to keep a firm grip on their actions even after death was pure wishful thinking.
Besides, the conditions for using Rinne Rebirth were extremely demanding, and the caster paid with their life. Black Zetsu isn't bringing it up now because he wants me to use it, is he?
After thinking it over, Obito looked at Zetsu beside him and said coldly, "We'll discuss it later. Even he couldn't turn this situation around. Don't forget, Orochimaru still has the reincarnated First Hokage. What could Madara do even if he came back?"
After the battle in the Land of Rice Fields, Obito had witnessed the strength of the First and Second Hokage. They were indeed far stronger than the current Five Kage.
Both the First Hokage's masterful Wood Release and Tobirama's Flying Thunder God Technique had caused him considerable trouble.
Yet Nagato had still trapped the First Hokage inside Planetary Devastation. Madara Uchiha, whose reputation matched the First Hokage's, was probably no better.
Even if a Madara Uchiha of that strength were resurrected, he could not play a decisive role in the current situation.
Zetsu remained expressionless beside him. Hashirama Senju and Madara Uchiha were the strongest chakra reincarnations he had ever seen. Their strength was beyond anything Obito could imagine. Underestimating them like this would only cost Obito dearly.
But warning him was not Zetsu's responsibility. Letting Obito retain that confidence would better serve
