Hunt Ghosts with Science, Stay Away from Superstition

Ghost Hunting and Taoist Stories, No Female Lead, but a Male Lead Is Fine

Looking for Realistic Ghost-Hunting Novels About Taoist Priests and the Like

Ghost Hunting with a System: Human or Ghost Protagonists Are Both Fine, but No Horror-World Settings

Looking for Stories About Catching, Killing, and Brutally Exorcising Ghosts, With Ghosts Terrified of the Protagonist

The protagonist can have a heroine or not, but the protagonist shouldn’t be a woman. Those stories aren’t interesting to me. I want a normal guy who’s so terrifying that even ghosts are scared of him when he’s hunting them. A System is optional!!!

Paranormal Stories with a Touch of the Occult, Serious and Grounded, Without Over-the-Top Posturing
