Plot
Detective Ding Qi accidentally gains the ability to time travel five times a day. These are not infinite loops, each cycle resets at midnight, and everyone loses all memory of previous iterations, except for a select few who retain all their memories. Ding Qi leverages the first four iterations to gather clues and evidence, enabling him to prevent crimes by the final loop. The plot intensifies when a cryptic murder warning surfaces from a suspect named "Squid". Ding Qi grows suspicious that "Squid" may also possess time loop abilities, given the changes in the subsequent loops. As the investigation deepens, it leads to a genetic biotechnology organization MOMA, where executives died one after another. Each clue may conceal a trap; each ally may harbor betrayal. Ding Qi's special ability makes him both invincible and fragile; each cycle tests his resolve and grants deeper insight into his powers. Thus begins an intense pursuit across time and space, as Ding Qi and his team race to gradually unravel the mystery that could alter their reality.- Time Cycle Perceiver: A person who has full recollection of the previous four cycles.
- Ultimate Cycle Day: The 5th and final loop, the most challenging cycle due to the presence of others like Ding Qi, who retains their memories and continuously alter the course of events.
- Mobius Strip: Where the detective’s pursuit and the villain’s evasion spiral cyclically through cracks in time and space. Truth and deception become indistinguishable.
