Deep in the dark underground, the elderly Madara, aged almost beyond recognition, nearly died of rage because of Black Zetsu.
Had the Demonic Statue of the Outer Path not been sustaining his life, how could the elderly Madara have survived such a blow?
Mouthful after mouthful of blood spilled from his lips, like the fragments of his shattered dream.
In the textbook from another world, Tobirama had written an exceptionally detailed account to prevent Black Zetsu's serial scams from happening again, listing that lump of sludge's many crimes-
They included turning the brothers Indra and Asura against each other, making the Senju and Uchiha enemies for generations, and altering the Uchiha Stone Tablet, along with many other things the elderly Madara knew or had never known.
Tobirama had even written that Black Zetsu's goal was to cast Infinite Tsukuyomi, gather all the chakra in the world, and resurrect Kaguya, the Progenitor of Chakra.
Faced with this horrifying truth, however unwilling the elderly Madara was to believe it, he had to admit-
The struggles, sacrifices, and efforts of more than half his life had all been for an outright lie.
At that moment, despair consumed him. He even considered abandoning everything, severing the tubes behind him that sustained his life, and seeking release in the elusive Pure Land.
But Madara could not accept it.
His revenge, his dreams, his unfinished work... everything burned through his soul like fire.
All around him lay devastation. White Zetsu corpses sprawled in heaps, piled like mountains. Only Uzumaki Zetsu had escaped, cowering in a corner, trembling and curled into a ball of terror.
The instant he realized he had been deceived, the elderly Madara snapped. He summoned all the remaining White Zetsu, then slaughtered them.
He roared for Black Zetsu to show himself at once!
