In the modern city of Hongdu, which is made of steel and concrete, spiritual energy is as thin as dust, and cultivation has become an unattainable legend. Takeaway boy Lin Yuan, a low-income young man struggling to make ends meet, accidentally stumbled into an abandoned old house on his way to deliver orders to avoid a heavy rainstorm, and accidentally picked up a broken ancient book covered with patina. This inconspicuous piece of "trash" is actually a fragment of the Jiuxiao Xuantianjian, a treasure left behind in the ancient world of cultivation.
The fragments of the ancient mirror were quietly integrated into Lin Yuan's body, not only giving him a weak sense of spiritual energy and a strong body, but also allowing him to see "qi" and "evil" invisible to ordinary people. In order to survive, he used this "eye of the sky" ability to work part-time as a "metaphysical consultant" who dealt with urban ghost stories and Feng Shui phenomena, quietly exploring the whereabouts of other fragments in the shadows of the city.
At the same time, Su Li, the beautiful owner of the mysterious antique shop "Wangyouzhai", looks cold and distant, but is actually a "lawful person" sent to the human world by the reclusive cultivation sect "Tianyin Pavilion" to secretly maintain the boundaries between cultivation and secularity. She was keenly aware of the abnormal fluctuations in Hongdu's aura, and the source pointed directly at the seemingly ordinary delivery boy. Su Li shoulders the responsibility of monitoring and evaluation. If Lin Yuan loses control or exposes the secrets of the world of cultivation, she will "erase" him at all costs.
