When the Rain Falls into the Abyss

On a rainy night by the seaside, former detective Lu Chen's detective agency received a panicked woman seeking help - her husband, Chen Ming, an architecture professor who studied the repair of a century-old bell tower, disappeared mysteriously, but the police hastily closed the case with "voluntary departure". Lu Chen realized that there were many doubts and sneaked into the closed bell tower which was under repair late at night. He found dried blood on the third floor and found an old diary and a mysterious copper key from the secret compartment that recorded the strange secrets of the Republic of China. The ghosts in black robes from a hundred years ago, the sound of footsteps in the middle of the night, and the hidden conspiracy in the bell tower emerged one after another. A black figure with a scar suddenly appeared to obstruct the investigation, and they fought fiercely with him. As the clues are peeled off layer by layer, a dark secret that spans the ages gradually becomes clear, and the whereabouts of Chen Ming's life and death are hidden deep in this chilling bell tower.
