Starting from Receiving a Call from My Deceased Mother, I Started to Connect to Another World.

"Pier 7" [Urban Superpowers + Suspense and Puzzle Solving + Parallel World + Ordinary People's Survival] At 2:17 in the morning, emergency dispatcher Shen Yan received a call. It was his mother who asked for help. But she has been dead for eight years. Eight years ago, he was busy on duty and missed six phone calls from his mother. Every time he changed his phone after that, he would save the number that he could no longer reach. This time, he answered. From that night on, Shen Yan had a map in his mind: a sealed corridor leading to another hospital, and an abandoned dock hiding a still-functioning city. On the other side of the door, there was someone with the same face as him, living a life he had never had. There are also people who are using these doors to bring back lost people. Shen Yan wanted to know if her mother was among them. Until he discovered that in that distress call, there was a voice from tomorrow afternoon that had not yet happened. And the person on the phone was desperately trying to stop him from saving people.
