A person's innate spiritual root is hidden deep within their soul.
Generally speaking, even a powerhouse who has reached the Ninth Transformation of the Saint Immortal Stage would be unable to interfere with someone's innate spiritual root without damaging their soul.

Unless, that is, one possesses special techniques specifically designed for innate spiritual roots. Yet, such techniques exist only in legends. At the very least, Li An had never heard of anyone who had mastered them.
