Chapter 48: Joining Forces Against Otsutsuki Kaguya, Boastful Words
It was no surprise to Uchiha Jobu that Otsutsuki Kaguya had left herself a means of resurrection. He had simply forgotten that, in the original plot, Uchiha Madara had been backstabbed by Black Zetsu at the very moment he had already gained invincible power. He had been the strongest god in the entire Ninja World, yet Black Zetsu had still managed to land a successful strike.
It turned out that Black Zetsu was not powerful. Rather, during the divine battle a thousand years ago—or perhaps even earlier—Otsutsuki Kaguya had left part of her data inside the Ten-Tails, giving herself a chance to resurrect.
No matter who became the Ten-Tails Jinchūriki, Otsutsuki Kaguya could be reborn through their body. But without Black Zetsu's sudden intervention, even if Otsutsuki Kaguya had resurrected, it would have taken an extremely long time.
Just like Isshiki, she would have needed to accumulate power slowly, restoring her data bit by bit. The process might have taken one or two hundred years, or even longer.
However, when Naruto: Shippuden ended and the story of Boruto, the son of the Seventh Naruto, began, Momoshiki Otsutsuki had driven part of his data into Boruto Uzumaki's body before dying. It had not only become Boruto Uzumaki's cheat ability but also his caretaker.
Thus, when Otsutsuki Kaguya seized his body, Uchiha Jobu could clearly see the Ten-Tails residing within him transforming his Sage Body at an even higher level. Even the strength of the chakra in his body could still be increased.
"Damn it! If I didn't have a system, but only this lousy treasure-chest-opening cheat, would I still be suppressed by an old hag like you?!"
For the first time ever, Uchiha Jobu felt that his cheat ability was pathetically weak.
