Mobius

"When a detective learns he can rewind time, he uses his ability to solve complex cases — until he encounters a meticulous killer with their own power".

Mobius (2025 Chinese series) follows detective Ding Qi, who gains the power to loop a single day five times to solve crimes, but finds himself in a time-loop battle with a mysterious killer (Suspect X) who might have the same ability, uncovering a conspiracy within a genetic research group in a city resembling Macau.
