Banished Immortals who retained all their memories, as appeared in transmigration novels, were as rare as phoenix feathers and unicorn horns throughout all of Shenzhou. In modern times, the only ones with this possibility were of the Demon Emperor of the Xi Clan and the Holy Emperor Venerable, Master of the Heaven Splitting Dao. For ordinary cultivators, even a Banished Immortal who retained some memories was a terrifying existence, let alone one with complete memories.
Most Banished Immortals did not have any memories of their past lives, possessing only a vague intuition that told them how to utilize Spiritual Energy— and this intuition often stemmed more from firsthand experience than from the deeper theories upon which the Modern Cultivation Method was based. They didn't even know if they continued the "personality" from their past lives; if we go by empiricism's "memory equals self" stance, they could be considered as having been reborn entirely.
