The system explained, "Just a minor Demon God. He does not belong to the Ninja World. He must have exiled an item carrying his belief into this Ninja World, where someone discovered the power within it and manifested it as a type of Ninjutsu."
"He also devours other people's souls to gain greater strength, which nourishes his true body."
"However, even his true body only comes from a Low-tier Plane, so he will not be very powerful. Separated by the endless cosmos, his Belief Projection is even weaker, possessing less than one ten-thousandth of his power. Naruto, your Spirit Passage Fist can break it," the system said.
Hearing the system's words, Naruto fixed his gaze on the Shinigami's projection and began to ponder.
Naruto had actually learned about the S-rank sealing Ninjutsu, Reaper Death Seal, from his father, Minato Namikaze, long ago. When Minato Namikaze passed all the Ninjutsu he had learned in his life down to Naruto, he had also passed the Reaper Death Seal on to him.
Naruto had also learned from his father that Minato Namikaze had used the Reaper Death Seal to seal half of the Nine-Tails' Chakra—its yin-nature Chakra—as well as part of his own soul, inside the Shinigami's stomach.
If that was the case, couldn't he take the Nine-Tails' yin-nature Chakra and part of his father's remaining soul back from the Shinigami's stomach?
Although, according to the system, once he stepped onto the Eternal path in the future, he would already have extracted enough remnants of his father's and mother's souls from his Adamantine Seal to revive them.
Still, just as the system had said, a minor Demon God dared covet his father's remaining soul.
Once his body became sanctified in the future, he would definitely cross endless time and space to beat that
