Corpse Whispers at Pier 7

Only Xu Yan could see the last twenty-seven seconds left by the dead man. Before the old building in Chunxili was demolished, Fang Qiaoyun, who lived in No. 402, Died. Her mouth was sewn shut with black thread, and she held a brass key in her hand. Before she died, she only said one sentence: "404, the door is open." But there was no 404 in that building. What's even weirder is that the deceased's cell phone received a call from ten years ago. The caller was Xu Yan's sister Xu Tang, who had already fallen to her death. In order to investigate old cases, Xu Yan had to reunite with Lin Wanzhou, a forensic doctor who had been separated for three years. One can hear the remnants of the deceased, while the other only believes in autopsies and evidence. A pier on a rainy night, an abandoned freight elevator, erased surveillance cameras, and a death list with the names of four people on it. When the corpse whispers at Pier Seven rang out again, Xu Yan realized that there had never been more than one person pushing his sister downstairs.
