Shinfū was the reincarnation of Orochimaru from his previous life.
The wind he brought helped Sasuke rekindle the flame of conviction!
—Immeasurable Void!
Sasuke unleashed the Rinne Sharingan dōjutsu that had ended Māra all those years ago!
As that pitch-black realm enveloped the void... every blazing spectacle Shi Mei had conjured with Daikokuten faded into oblivion!
The ninjas' attacks, however, remained intact. They surged skyward all at once and struck Shi Mei without inflicting any damage.
The reason was simple: Void Māra had already adapted to these attacks.
Purging every phenomenon within the Dharma Realm that arose from chakra other than the caster's—this was what Immeasurable Void could accomplish regardless of the disparity in strength!
But after all these years of subjugation and evolution, everyone had already adapted to Immeasurable Void.
Thus, the phenomena they created would not be purged.
"Sasuke!!" Seeing Sasuke recover his resolve, everyone found their pillar of strength again.
Shi Mei said, "Oh? Immeasurable Void. You finally used it. But you should know perfectly well, shouldn't you? This is nothing more than a way to prolong your last gasp..."
Shinfū came to Sasuke's side, his voice hoarse. "In my previous life, I sealed a technique within my soul and brought it into this body through reincarnation. Shinfū's power cannot activate it. But you can, Sasuke-kun—with the condition that you stand on the brink of utter desperation."
Sasuke asked, "Even Shi Mei doesn't know this technique exists?"
Shinfū said, "Clairvoyance and Ten Directions aren't truly all-penetrating. There is one place in this world that even Shi Mei's divine sight cannot reach."
"That is the world after death, Underworld Yomi."
"Before my reincarnation, I made a bargain with the King of the Underworld. He sheltered me, keeping Shi Mei from sensing me."
"How do I use that technique?"
