The Hsien jumped from one cadaver to another by touching each one with his hand, reanimating corpses while he inhabited them. It cannot remain within a corpse indefinitely as the cadaver continues to decay despite the presence of the Hsien within it. The Hsien can only exist within a corpse for only several hours (or perhaps a couple of days). If the corpse is destroyed, in particular the brain, the Hsien dies with it.
There does not seem to be a limit to how many bodies a Hsien can jump through. In the morgue, the Hsien was shown jumping in and out of five bodies quickly in order to reach a corpse at the end of the row of tables that held cadavers.
Literally, "an immortal", living on or above the earth, but within natural things, a material immortality in which the body was still needed, however preserved in a "lightened" form. Hsien were Taoist immortals, supposed to have partaken the elixir of life, and in early illustrations they often appear as feathered men. The ancient Chinese believed in the existence of drugs which could be taken for this purpose.
