'Soul', a thing in a superposition of existence and non-existence.
The soul is a pseudo-proposition; when observed, it cannot be found, yet some indirect evidence confirms that this thing truly exists.
Even elves can't figure out what the soul actually is.
Say it exists, but it doesn't truly reside within the body;
Say it doesn't exist, yet there are various signs indicating the soul's existence.
The soul is like a mischievous little thing, especially fond of playing hide-and-seek with people, and its hide-and-seek skills are unrivaled, no matter how the ghost-like searcher tries, it can't be found.
Just like now, they are observing the soul through Yulia's 'memory event' and have confirmed that the soul exists and can carry memories.
If you really go looking for it, you won't find it.
After listening to Yevgenia's explanation, Yulia fell silent, then sighed and stopped dwelling on the issue of the soul.
