In the dead of night, a shadow streaked across the sky, landing in the courtyard after evading the surveillance camera on the wall. The security office at the gate was still lit, and inside people bustled about.
The shadow didn't linger but proceeded straight in, seeming very familiar with the surroundings, always able to easily dodge under the cameras without leaving evidence.
The City Police Department building is six stories tall; the first floor is the incident handling hall, the basement is the morgue, and the holding area for temporary detainees is behind the hall.
The shadow bypassed the empty hall and directly entered the third floor, if memory serves correctly, the archives should be in the innermost room on the third floor, while the research department is on the fourth and fifth floors, and the director's office and conference room are on the sixth floor.
