Chapter 30
He began preparing his masterpiece. Using **Copy** on himself was a paradox he had avoided, but now he attempted it. He focused not on copying his living body, but on creating a template of his biological and chakra data as it was *right now*. He poured a massive amount of chakra into creating a single, perfect, inert copy of his own form—a lifeless shell, a perfect replica.
Then, using fuinjutsu principles learned from Tobirama and his own devoured knowledge, he worked on a seal matrix. The idea was a "Soul Anchor" seal, incredibly complex and theoretical. If his body was killed, his consciousness—his memories, his skills, his very soul—could theoretically transfer to this prepared, vacant vessel. It was a lich's phylactery, a ninja's failsafe.
