The rain in Nancheng was like a string of beads that had been torn apart by someone, crackling on the asphalt road and splashing water half a foot high. Lin Feng parked the police car outside the iron gate of an abandoned factory in the suburbs. The wipers swung wildly from side to side, but they still couldn't wipe away the rain on the windshield. He opened the car door, and a fishy smell mixed with rust and dirt hit his face, making him shiver with coldness.
