Jing Uchiha's heart jolted. Through his Rinnegan, he saw Kazan's battered body rapidly regenerating.
It was not healing through Medical Ninjutsu. His body was regenerating on its own, his blood boiling and every cell within him pulsing.
An inhuman body!
Jing Uchiha had never seen anything like it. Even with the First's cells integrated into his body, he could not achieve this. His cells were nowhere near as active as Kazan's.
"A Sage Body!?" Black Zetsu could not hide the tremor in his voice.
Jing Uchiha did not recognize the change in Kazan's body, but Black Zetsu knew exactly what it was.
It was a Sage Body like that of Asura, the Sage of Six Paths' younger son—a body almost impossible to kill.
"How could this happen?" Black Zetsu could not understand it.
Kazan had never possessed Asura's reincarnated Chakra. He did not even have a trace of Otsutsuki blood. He was an ordinary human, yet he had developed a Sage Body.
Genius was no longer enough to describe Kazan. Konoha's Ghost God had taken a crucial step into the realm of the Six Paths.
And he had not followed the path of Black Zetsu's mother, Kaguya Otsutsuki, who had devoured the Chakra Fruit and used the planet's energy to evolve.
Kazan had transformed and evolved through his own training.
A talent born once in an age!

Kazan threw another punch without retreating. His fist, wreathed in Crimson Lightning, sealed off the space around Jing Uchiha and slammed into his chest.

Kazan spat blood again, but his smile did not fade.
Few people in the world could hurt him anymore. Now, though, he was taking the force of his own attacks.
Blood spilled from
