Mist Ninja,
A dark voice sounded in the Mizukage's Office,
"Madara."
"Are we really going to keep wearing down the Mist Ninja like this?"
Black Zetsu asked,
"The Seven Ninja Swordsmen of the Mist have all fled and turned traitor."
"The Mist Ninja leaders have realized something is wrong."
"They'll probably make a move against Karatachi Yagura before long..."
"Besides,"
"Karatachi Yagura might not be able to hold out much longer..."
With his Mangekyo ability, Obito Uchiha could control both Karatachi Yagura and the Three-Tails at the same time, but it came at a cost.
As the leader of his village, Karatachi Yagura wasn't entirely powerless to resist. That resistance placed an enormous strain on his mental energy,
and even if Obito Uchiha released the Genjutsu now, the loss of his spiritual essence would still hasten Karatachi Yagura's death.
Obito Uchiha controlled Karatachi Yagura and said coldly,
"Whatever happens, Karatachi Yagura is still the Mizukage."
"The Mist Ninja leaders won't act so quickly."
"Besides,"
"Karatachi Yagura can hold out for quite a while yet."
"If it comes to it, we'll transplant Hashirama Cells into him and keep him going a little longer."
"The pain he caused Rin won't be settled just because he's dead!"
Black Zetsu fell silent, at a loss for words.
He couldn't exactly say, "Don't blame the Mist Ninja. It was all Uchiha Madara's doing."
"But the Mist Ninja really are of little use now,"
"apart from the Three-Tails..."
"But Nagato hasn't grown strong enough yet. We can't tip him off."
According to the timeline, Nagato was still getting used to the power of the Rinnegan. He hadn't yet reached the peak combat strength he would later command through the Six Paths of Pain.
"We should give up this damp land."
Obito Uchiha said indifferently,
Black Zetsu
