Ascension飞升
fēishēng
The leap from the mortal world to a higher plane of existence, the traditional endgame of a cultivator's path.
Feisheng, "flying ascension", is the moment a cultivator outgrows the mortal world: after surviving the final tribulation, they rise bodily into a higher realm, whether that is the immortal world, the god realm, or another layer in a stacked cosmology. Web novels love multi-world structures precisely because ascension resets the ladder; the strongest person in one world arrives at the bottom of the next.
Ascension also explains the genre's power vacuum logic: the ancients were stronger "because the world's qi was richer then", and the mighty are absent "because they ascended". Series like Stellar Transformations and Renegade Immortal structure their entire runs around successive worlds and the ascensions between them.
