(System, ghosts and monsters, one heroine, satisfying, leveling up to survive, Daoist arts... Adapted from traditional Chinese metaphysics. Please don't mind.)
Yulin transmigrates to a parallel world, Blue Star, where folk supernatural arts have fallen into decline, and activates the Daoist Arts System.
Ghosts and monsters are returning. Every night, hundreds of ghosts roam the streets, appearing in large numbers to slaughter humans.
While celebrities fill their homes with Buddha statues, the protagonist draws yellow talismans by hand and slays ghosts barehanded.
Every time he slays a ghost and saves someone, he can improve his Daoist arts.
The art of drawing talismans lets him face fierce ghosts alone.
Talismans and formations let one person fight a horde of ghosts.
Talismans combined with modern technology.
Runes carved onto firearms? Rune bullets?!
Carved onto a longsword? Flying on a sword?!
Using the Eight Trigrams to divine and calculate, drawing upon the energy of heaven and earth...
As Yulin saves more and more people, the entire world seems to revolve around him.
The nation's top officials:
"Wonderful, the Immortal Yulin is here!"
Other countries:
"We must do everything we can to curry favor with the Supreme Immortal Yulin!"
The ghosts and monsters:
"The elderly and children go first!"
"Run! There's a ghost!!"
The protagonist isn't a saint; they only protect their own allies. I've always written this character based on this template, so I hope there's no misunderstanding. New author, new book, please offer your support and understanding.
