The summary is quite misleading. I thought I was going to read yet another clichéd urban cultivation story, but this is actually more of a supernatural horror story with a relatively light and comedic tone. MC is basically a spirit hunting exorcist, as his cultivation techniques are particularly effective against spirits, evil or otherwise. Spirits with quirks similar to ghosts in horror stories are the antagonists in this story, so far no mention of any spirit beasts or the like. I like how the MC is to evil spirits basically what they are to ordinary humans: their worst nightmare. Writing quality is decent, translation has some problems (mainly with gender pronouns), but I've read worse.
No romance so far, MC seems uninterested in such pursuits. He seems mildly sociopathic; he mostly acts ethically, but I get the feeling that it's more because he knows intellectually the difference between right and wrong and what is lawful or criminal, rather than it being an instinct coming from his conscience and empathy towards fellow human beings.
Anyway, in conclusion, it's a fairly amusing and entertaining read, different from the most popular cultivation story formulas. I can recommend it, particularly if you like ghost stories and supernatural mystery.
