In a dark Underground Base.
Zetsu emerged from the rock wall.
"Damn it... the Rinnegan was destroyed after all..."
Black Zetsu cursed under his breath, then walked over to one side of the rock wall.
Several transparent containers stood there, holding four intact Rinnegan eyes.
It was hard to imagine that Black Zetsu had actually hidden away two pairs of the Rinnegan, known as the Sage's Eye.
Black Zetsu had existed in the shinobi world for over a thousand years and had witnessed several reincarnations of Asura and Indra. Each time, he stirred up trouble, messing with Indra's reincarnation's mind.
The Rinnegan had been successfully awakened three times, and Madara Uchiha had been the third.
Black Zetsu wasn't panicking over the destruction of Nagato's Rinnegan precisely because he still had these two pairs.
Besides those two pairs of Rinnegan, Black Zetsu had accumulated quite a few other means over the past thousand years.
The first was reviving the Ten-Tails using portions of the tailed beasts' chakra.
Black Zetsu had begun this experiment long ago, and it had been quite successful. But actually reviving the Ten-Tails and casting Infinite Tsukuyomi would take a very long time, because... the chakra he had gathered was far too little compared to that of the actual Nine Tailed Beasts.
In the original story, when Obito failed to capture the Eight-Tails and Nine-Tails, he had used the brothers Kinkaku and Ginkaku, who possessed nine-tails chakra, along with an octopus tentacle from the Eight-Tails as substitutes.
Beyond that, Black Zetsu had also created the Land of Earth's Dust Release and taught it to the Tsuchikage of that time.
Dust Release was immensely powerful and had a chance of destroying the moon. What Black Zetsu hadn't expected was that each successive Tsuchikage would be worse than the last.
