('Of course, this alone probably isn't enough to discover one's Martial Path and break through to the Apprentice Realm.') Rui noted.
For example, if their Martial Path happened to be related to a non-standard field like poison, then no amount of self-awareness of their existing style and combat would be able to allow them to discover their Martial Path until they were actually exposed to poison.
Of course, it was highly unlikely that they had Martial Paths related to poison. Now that Rui had gained access to some lesser-known secrets of the impact of one's personal experiences throughout their life on their Martial Path, he knew that their life experiences would almost certainly not morph their Martial Path into something niche and esoteric.
Furthermore, Rui already had some suspicions about their Martial Paths.
