"It's natural to crave power, but I hope you aren't foolish enough to get yourselves killed."

Uchiha Ensei had prepared One's Own Life Reincarnation as a fallback for himself.

Because he practiced the Spirit Transformation Technique, his soul had gained a degree of independence. Even if his body was damaged, he could survive briefly in spirit form.
