In 2077, Interpol's ace team, technical expert Ling Yunche and operational expert Mu Wanxing, were caught in the turbulence of time and space while hunting down space-time criminals, and both died.
When they woke up again, they found themselves back in the year 2000, a "prehistoric era" when BP machines had not yet been eliminated and dial-up was required to access the Internet. They also turned back into "rookie" police officers who had just graduated from the police academy and were assigned to the city bureau's archives.
Facing the dusty unsolved case files, Mu Wanxing smiled: "I have seen standard answers to these cases in future crime museums."
Facing the dilapidated 586 computer, Ling Yunche sighed: "Forget it, let's start from scratch. Let's get you a 'Skynet' system to play with."
As a result, colleagues in the Municipal Bureau were shocked to discover:
The quiet file administrator Ling Yunche can hack into the server of an international gambling group with a few lines of code; the beautiful trainee policewoman Mu Wanxing can accurately draw a suspect's appearance ten years from now with a blurry surveillance screenshot.
While others are still struggling with fingerprint comparison, they have already used "homemade" DNA sequence matching and facial recognition.
The criminals were completely devastated: What happened to the police this time? We felt like we were running naked!
