In another manhwa, it is said that the scent of the Mt Hua's peach blossom flowers is **NOT** the mark of the epitome of their swordsmanship.
It is a by-product of a using ki to trigger pheromones to smell like the flower. But this also meant certain ki **leaking**. The true perfection of this is to eliminate the leaking ki and hence become 100% efficacious, where the ki flows back as a loop, becoming ever-flowing, never-ending. In Chinese this is called 连绵不断，生生不息.
