[Demon-slaying and evil-exorcising] + [character traits] + [true love] + [multiple heroines]
Shen Gui transmigrated into a strange world and became a wandering Daoist priest.
With the help of a System that let him see ghosts' character traits, he took on small exorcism jobs to scrape by.
Until one night, while staying in a ruined temple, he was visited by a female ghost in a wedding dress, her face covered by a red veil.
He couldn't beat her or escape, and she possessed him.
In his muddled consciousness, he saw fragments of her life: a grand Shen family mansion, a mountain, and a sinister ghost wedding.
Shen Gui made a Daoist pact with her: “I'll help you fulfill your last wish, and you'll leave me alone.”
The female ghost agreed, leaving behind a rusty copper token before falling into a deep sleep inside him.
From then on, he carried an unknown vicious ghost with him and used a copper token whose inscriptions he couldn't make out to ask around for the whereabouts of a mansion belonging to a family named Shen.
A human sacrifice concealed by a mining company, a scheme to nurture evil spirits in the ancestral grave of a wealthy merchant in Fengtian City, a fox immortal who had attained the Dao in the Changbai Mountains…
He only wanted to uncover the secret of the copper token, but one bizarre incident after another kept pushing him forward.
The upgrade flow has average folklore descriptions, mainly about fighting monsters and upgrading and a few female protagonists. It's okay, and it's good for being a source of food.
