At four o'clock in the morning, the fishing bay was still immersed in the thick ink-like night. Only the old LED light on the west side of the pier shone dimly, reflecting the fine ripples on the sea surface with cold white. Jin Kaiyin wrapped himself in a dark blue velvet jacket and walked out of the house. His rubber boots made a dull creaking sound when he stepped on the wet stone pavement. The salty smell of sea water from the roadside drainage ditch came up and over the edge of the soles of his boots, and a chill spread around his ankles.
