I'm reading a fictional book which deals with Japanese mythical/fantasy themes. One chapter describes dead people being resurrected through a complex operation in which their bodies were reworked and the procedure was referred to as "死鬼手技" by the man who conducted it.
Could someone help me understand the "死鬼" part? The only thing I can find is a Chinese definition meaning "devil" and my guess was "dead demons" but what would "dead demons" have to do with it?
