A young man raised in a Taoist temple, Lu Qingxuan, enters the bustling metropolis for the first time. Unversed in worldly affairs with his Taoist aura, he relies on folk wisdom from ancient books to handle mundane trivialities, causing quite a few hilarious blunders. However, bizarre incidents happen successively in the city; after putting on matching black wooden prayer beads, many people inexplicably suffer from insomnia and irritability. A mysterious hooded figure haunts them like a shadow, and eerie symbols frequently appear. Chen Mo, an office worker who took him in, and Lin Xiaoxiao, a warm-hearted neighbor, stay by his side. A scam under the guise of folk customs is surging undercurrents, and the newly arrived young Taoist approaches step by step, through everyday events, the astonishing conspiracy hidden behind the metropolis.
