Some details
Despite their names, Essence, Perfected, and Heaven immortal did not prevent dying from old age; they just extended one's lifespan to many thousands of years.

Golden Immortals would not die of old age (although they could still be killed), and thus truly immortal.

Once a Golden Immortal, a Qi cultivator could still become stronger and become a Perfected Golden Immortal, which may be the same as ninth-stage Golden Immortal. Beyond that one could become a Zenith Heaven Immortal (sometimes called Zenith Heaven Golden Immortal); and cultivate that until sixth stage.

After that, one could cultivate the Three-Corpse Slaying Technique, which could bring one to the Quasi-Saint Level.
