Shen Guan, a police officer from the general archives department, lost his girlfriend seven years ago and has buried the sadness. Seven years later, a copycat murder case with surprisingly similar techniques tore his dusty memory apart again. When he followed the clues and stepped into the legendary "Bell Tower District" where physical laws are disordered, what greeted him was not the truth, but a fatal chase and an icy fall. At the moment of death, his consciousness was pulled back to the same day seven years ago, but he entered the body of another victim. He must use this borrowed time to start a time-spanning game with his past close friends, enemies, and even himself in the body of another identity. Can we usher in a new life by changing the past? Or is this just another echo leading to a deeper abyss?
