Obito and Black Zetsu truly had not expected that damned fellow to have discovered their presence long ago.
Not only had he discovered them, he had even pinpointed their locations!
The chakra bursting from him now, in particular, carried the unmistakable power of Yin-Yang Release, leaving them utterly incredulous.
Both of them knew exactly what kind of power Yin-Yang Release was.
After all, Obito had been taught by Madara and Black Zetsu, and he had half a White Zetsu body as well as the Mangekyō Sharingan.
He could already be considered qualified to learn Yin-Yang Release, and he would also need to control the Tailed Beasts in the future.
Thus, Obito already knew some Yin-Yang Release, and there was naturally no way he could miss the change in the power within Xia Yan.
He was genuinely bewildered now. Yin-Yang Release was so difficult to learn. Why had this fellow mastered it?
Black Zetsu's expression was also extremely ugly. He was now even more certain that this damned fellow most likely had an Ōtsutsuki backing him as well.
Despite the clear presence of the Tailed Beasts in the Shinobi World, this fellow had a Nine-Tails inside him, and the technique he used had even manifested an Ōtsutsuki's phantom.
Now that he had displayed the power of Yin-Yang Release as well, it thoroughly confirmed that the fellow before him was exactly what he had suspected!
"Damn it, where did she come from? How long has she been here, and what did she come here for?"
Black Zetsu had instinctively taken the phantom that appeared behind Xia Yan during his previous technique to be an Ōtsutsuki.
But he had no time to think further now. Xia Yan had already begun to move!
Although Xia Yan could go straight after Black Zetsu and Obito,
