At the Evidence Center of Binhai City Public Security Bureau, a bizarre explosion kicked off a crime that lasted for thirty years.
Senior criminal police officer Li Jianguo stood in front of the blackened warehouse. In front of him was a perfect secret room: the door was locked from the inside, the vent was only the size of a palm, and surveillance showed that no one entered or exited before the explosion. The directional blasting accurately destroyed seventy-six pieces of evidence in the unsolved cases, but only bypassed the key evidence of the "Splendid Garden Falling Case" - as if an invisible hand was controlling everything.
As the investigation deepened, Li Jianguo discovered that this was not an isolated case. In the past five years, key exhibits in 17 unsolved murder cases have been "accidentally" damaged one after another: blood samples were inexplicably degraded, fingerprint membranes were mysteriously damaged, and surveillance videos were magnetized... On the surface, they were improperly preserved, but in fact they were a carefully planned "evidence annihilation project."
Su Xiao, the newly transferred criminal investigation technical consultant, discovered military-grade carborane in the explosion residue through spectral analysis - this is not a material that ordinary criminals can obtain. What's even weirder is that all the clocks at the scene stopped at 3:27, which is exactly the same as the time of death in an unsolved case thirty years ago.
The truth began to emerge when Li Jianguo discovered a black notebook filled with incriminating evidence in the underground secret room of the archives. The owner of the notebook is the "Five Musketeers" - the five elites who dominated the police force thirty years ago. Now, including Deputy Director Wang Zhigang and Prosecutor General Liu Zhenmin, they all hold high positions.
There was a yellowed photo on the last page of the notebook. The bloody words on the back made Li Jianguo feel like he was struck by lightning: "When the last guardian falls, the maze will be opened to the real owner."
