Li Xingwen transmigrated. He had arrived in his own body, and after collapsing by the roadside, he was taken in by the Liu Dong family of Ryuudou Temple.
Since this wasn't Fuyuki City, Li Xingwen didn't think much of it at the time.
But when he discovered that the martial arts he'd practiced in his previous life just to strengthen his body had, in this life, developed mysterious powers that should have existed only in fantasy, he realized that there was definitely something wrong with the world he'd transmigrated into.
Perhaps the mysterious has a power of attraction, because one strange incident after another kept happening.
At night, the dead wandered the streets, and the one creating them seemed to be a vampire.
A student at the school where he worked turned out to be a demon young lady.
A guest who called herself Medea came to stay at Ryuudou Temple, the very place that had once taken him in.
Faced with threats both overt and covert, Li Xingwen clenched his fists.
