Madara Uchiha stared in disbelief at the phantom slowly appearing in the sky and struggled to speak. "Th-this... impossible. How could this be possible?"
The black chakra on Madara Uchiha's chest slowly formed Black Zetsu's head. He grinned smugly. "You didn't see that coming, did you, Madara Uchiha? You never imagined I'd leave a Forbidden Spell in your chest. The moment you activate Infinite Tsukuyomi, the Forbidden Spell in your chest activates too. I placed it on you while you were still alive, so you couldn't detect it at all. Heehee, hahaha..."
Madara Uchiha stared incredulously at the phantom formed from Black Zetsu's chakra before him. "You say you placed that Forbidden Spell on me while I was alive? Impossible. How could you tamper with my body without me noticing a thing? That's impossible."
Black Zetsu laughed smugly. "Nothing is impossible. How do you think I evaded Hagoromo's pursuit? I, Black Zetsu, was born of Mother, after all. Though I didn't inherit Mother's tremendous power like Hamura and Hagoromo, I can conceal my presence from everyone. Even Hagoromo couldn't detect my existence. Tampering with your body was child's play. Hahaha! You never expected this, did you, Madara Uchiha? You thought victory was assured and everything was under your control, never imagining that you, too, were merely one of my pawns. Though there were plenty of unexpected setbacks along the way, and even I died without knowing how, you still completed Infinite Tsukuyomi. That makes it all worthwhile. Mother will descend upon this world once more, and everything will be hers to decide."
Madara Uchiha roared in defiance, "Impossible! How could I, Madara Uchiha, let you succeed? I am myself! Everything must be decided by me!" He tried to regain control of his body, but it could no longer move. With
