Just like that, Soji temporarily settled down in one of Orochimaru's research bases.
The next day, Orochimaru handed the forbidden technique Living Corpse Reincarnation over to Soji.
Of course, with time being urgent, Soji immediately began studying Living Corpse Reincarnation at Orochimaru's research base.
Whenever he encountered something he did not understand, Soji would take the initiative to ask Orochimaru.
This greatly accelerated Soji's progress in learning the forbidden technique Living Corpse Reincarnation.
Strictly speaking, this was the first time Soji had formally studied a ninjutsu under Orochimaru since becoming his disciple!
And as a teacher instructing a student in ninjutsu, Orochimaru truly could be considered wholeheartedly dedicated.
Since he had decided to pass the forbidden technique Living Corpse Reincarnation on to Soji, Orochimaru would not hold anything back simply because it involved the secret of his immortality.
With Orochimaru, the pioneer, guiding him, coupled with Soji's naturally far faster learning speed in ninjutsu compared to ordinary people, he quickly got the hang of the forbidden technique Living Corpse Reincarnation.
To put it plainly, the hardest part of learning Living Corpse Reincarnation was figuring out how to split off one's own soul.
Furthermore, after splitting one's soul, one had to ensure it did not cause overly severe harm to oneself!
Take Orochimaru, for example. After perfecting Living Corpse Reincarnation, the only weakness left to him was his drastically reduced resistance to genjutsu.
Even after Orochimaru later transplanted the Byakugan, his resistance to genjutsu could only be called average.
Of course, this weakness was practically nonexistent for Soji.
He refused to believe that, with his level of Dojutsu Power, anyone could still control him with genjutsu.
Unless Kaguya Otsutsuki was resurrected!
Once Soji mastered Living Corpse Reincarnation, he could use the Spirit Transformation Technique to freely control the souls he had
