Zhou Yanqing is a third-year student specializing in criminal investigation at the Guangdong Provincial Police Academy in Huaguo. All she wanted was to complete her practical training, graduate, and join the police force as planned. But just before a closed training exercise, she was chosen by a cold, emotionless “Criminal Investigation System.”
From that day on, she began traveling through parallel worlds.
A training base cut off by torrential rain, an ancient county town governed by rigid ritual, a foreign manor with unfamiliar rules, a modern metropolis concealing undercurrents... In each world, she must assume a new identity and enter the investigation, digging out the truth bit by bit with limited authority, limited time, and limited clues.
The System won’t solve cases for her. It only gives her rewards when each investigation is complete.
Footprint analysis, crime-scene observation, interrogation strategies, timeline reconstruction, behavioral pattern analysis...
What she receives is never the answer, but the ability to get closer to it.
But as she solves more and more cases, Zhou Yanqing gradually realizes that these worlds aren’t isolated from one another, and the System didn’t choose only the cases. It chose her, too.
She’s pursuing more than the killer.
She’s also chasing the altered timelines, the buried responsibility behind each murder, and the real truth hidden at the end of countless parallel worlds.
