The Prince of Lanling was a figure from a thousand years ago.
A millennium has passed, which, by any calculation, doesn’t amount to many generations. An ordinary person might live to be eighty or ninety, and with a focus on longevity, perhaps over a hundred. As for a martial artist, even one with the lowest level of cultivation could easily live past a hundred.
The Eighth Realm is a major threshold for martial artists. Before reaching it, one might live to be 160 or 170. Once a martial artist crosses into the Eighth Realm, their lifespan increases dramatically; living to two hundred is no problem at all. And the Ninth Realm? Although Jiang Chen has never met anyone in the Ninth Realm and doesn't know how long they can live, a reasonable estimate would be five hundred years.
