At that moment, Tobirama Senju suddenly came to a realization. He finally understood why he had miscounted one person.
It turned out that the last one could not be considered a person at all, because that fellow was named Black Zetsu.
If Black Zetsu learned what Tobirama Senju was thinking, he would definitely confront him face-to-face without hesitation.
After all, he was Kaguya Otsutsuki's third son. How could he not be counted as a person?
While Tobirama Senju was deep in thought, Black Zetsu quietly began moving in secret.
Like a ghost, he silently crept up beside Uchiha Yato, trying to close the distance so that he could possess him.
To avoid attracting anyone's attention, Black Zetsu had deliberately turned himself into a black cat.
That way, even if someone happened to catch sight of him, they would only take him for an ordinary cat and would not suspect a thing.
But Black Zetsu seemed to have forgotten that this was a battlefield. Even the dumbest person would know that no ordinary creature could possibly appear here.
Black Zetsu secretly calculated that as long as he was given a suitable opportunity, he would charge at Uchiha Yato with lightning speed and possess him in an instant.
Once Uchiha Yato was under his control, the rest of the plan would become effortless.
Black Zetsu would make full use of Uchiha Yato's power and drag everyone present into a massive storm.
"Given the current situation, shouldn't we step in too?"
Madara Uchiha knew Black Zetsu's abilities all too well. The reason he asked was actually to gauge the attitudes of the two people beside him.
Back in his own world, after Uchiha Yato killed Hanzo of the Salamander, Madara Uchiha now felt that Black Zetsu had been pulling strings behind the scenes.
