Under the neon lights of bustling cities, there is a juncture of yin and yang invisible to ordinary people.
Lin Chen, the last descendant of the declining Xuanmen family, guards an antique shop called "Qi Men Pavilion", fortune telling and feng shui during the day, and drawing talismans to catch ghosts at night. He thought he was just guarding his ancestral business in this life, but because of a "nightmare case", he bumped into Su Qing, a reporter who was looking for the truth.
From haunted old houses to ancient tombs densely packed with institutions, from evil spells that tamper with fate to conspiracies that shake the dragon's veins, Lin Chen holds the yellow talisman and steps on the compass. With Su Qing's "modern assistance", he gradually uncovers the truth behind the urban anecdotes - all of this is closely related to the mysterious death of his grandfather, the ancient secret treasure guarded by the family, and a mysterious organization called "The Underworld Society".
When the fortune teller calculated the calamity of death, when the Feng Shui array trapped the resentful spirits, and when the rice dumplings in the ancient tombs opened their eyes, Lin Chen understood: the so-called successors of Xuanmen not only guard the craftsmanship of their ancestors, but also the balance of yin and yang in the world.
And Su Qing also gradually discovered that the charms written by this seemingly cold young man could ward off evil, and the temperature in the palm of her hand could warm the heart. Even her worldview, which did not believe in ghosts and gods, quietly collapsed and was rebuilt in the battles fought side by side.
"Lin Chen, where will you go for the next case?"
"First calculate your luck today - well, the hexagram shows that it is right in front of you."
Qi Men Dun Jia in the modern city, the symbiotic game between man and spirit, an urban adventure that begins with strange news and ends with protection, begins here.
