In short, cultivation genre contains action and it's like an enlightenment aspect gained by the soul (this can be mental, physical, psychic, etc. and covers various elements of either nature or something unknown) which can be increased through willpower, (not everyone can have cultivation potential) consumption of specific/precious pills, gaining opportunities (fate/destiny) , legacies, secret treasures specifically cultivation, Qi absorption and so on.
Cultivation follows romance in general due to improvement in body and it being harder to live a lonely life above 100s and 1000s of years as they are defying heaven. As a side effect, they face inner demons of their karmas, whether good or bad. That also depends on the plot how they utilise their wits on different aspects.
Does it have a tragic ending?
