Deep Sea Mystery

Lu Chen picked up a soaked letter at the beach. His name was on the envelope, and there was only one sentence written inside: Don't go home tonight. That night, a black stone slab was exposed on the beach at low tide, and something in the sea called his name. The black ocean that he had dreamed about repeatedly since he was a child was becoming clear little by little. The dead man in the dream had his face. The old files in the city read: Three hundred years ago, a man named Lu Chen also disappeared. "I've seen you many times." The silver-haired girl said. "Welcome back." Hai Hai said. He had walked this road six times, and each time he died before the light came on. This is the seventh time.
