At two o'clock in the morning, electronic forensics expert Lu Li received a high-temperature carbonized occipital bone fragment, along with a line of text:
"This is the seventh number. The first six can no longer be tested."
Three years ago, his master died in an "accidental explosion" and three fingers of Lu Li's left hand were blown away. The physical evidence he personally extracted was inconsistent with the files on file.
Now, the murderer is back.
Case of corpse dumping on a rainy night - the takeaway rider had a perfect alibi because his GPS trajectory was falsified using an algorithm.
Elevator secret room case - surveillance showed that no one entered or exited during the time of the crime because the murderer tampered with the log of the floor controller.
AI voiceover case - the deceased "personally" admitted that she was still alive because someone had cloned her voiceprint using deep forgery.
Behind every case, there is the same codename: Gray Owl.
An archive destruction network that allows the dead to "legally disappear" from the world.
Lu Li's crippled left hand tapped on the table, and the rhythm of the Morse code was messed up for the first time.
The evidence collection tools used by the murderer were written in his own hand.
