Beyond this seemingly peaceful world lies a mysterious town shrouded in mist: Yougu Town. Here, the boundary between reality and illusion grows blurred, and time no longer flows according to the usual rules.
Li Ming, an ambitious young investigative reporter, enters this eerie town to investigate a strange series of disappearances. He soon discovers that he has become entangled in far more than an ordinary case.
In Yougu Town, Li Ming encounters a mysterious old man in black robes, Su Yuqing, a nurse who knows the town's secrets, Lao Zhang, an eccentric antique shop owner, and Officer Liu, a secretive police chief. Everyone seems to be hiding something, and the town's ancient well lies at the center of every mystery.
As his investigation deepens, Li Ming gradually lifts the many veils hiding the town: an ancient cult, a secret passage to another world, and even the shocking truth about his own origins. He realizes that his connection to Yougu Town is far closer than he ever imagined.
Caught between reality and the supernatural, Li Ming must face his destiny and become the “gatekeeper” connecting two worlds. Every choice he makes will affect not only the fate of the town, but also the balance of the entire world.
