Even Kusana had to admit that this was an attempt spanning worlds, a great innovation combining ninjutsu and Devil Fruit abilities.
That was right!
Madara's revival this time had not succeeded solely because of Living Corpse Reincarnation; it had also required the help of the Paramecia-type Soul-Soul Fruit.
The Paramecia-type Soul-Soul Fruit could freely manipulate human souls, allowing them to inhabit all kinds of objects and anthropomorphize them, but it could not place them into human corpses or people other than the user.
Living Corpse Reincarnation, meanwhile, was a technique that transferred one's consciousness into another person's body, achieving a different kind of immortality.
After Madara's original Impure World Reincarnation body collapsed, his soul could not return to the Pure Land because it was in another world. In the end, Orochimaru used the Devil Fruit to gather it.
However.
The Soul-Soul Fruit had one drawback: it could not extract the soul of a powerful person who did not fear the Devil Fruit User.
And Madara... would he fear Orochimaru?
That was simply a joke. Let alone Orochimaru, even someone far stronger than Madara probably could not make him feel fear.
Thus, Orochimaru had still gone through quite a bit of trouble to collect Madara's soul.
Fortunately, this was not another world. Otherwise, the instant Madara's soul appeared, it likely would have returned directly to the Pure Land.
In the end, after gaining control of the soul and modifying the Living Corpse Reincarnation technique so the soul could temporarily enter a transfer station, then cultivating a clone of Madara using the cells he had left behind, they had finally succeeded in reviving Madara in a certain sense.
Of course~
This also owed much to Orochimaru being an expert at toying with souls. He had already revived himself multiple times through Living
