Ritual murders have occurred one after another in Shenjiang City - Internet celebrities were interrogated to death by barrage in live broadcast rooms, financial fraudsters were locked in their own vaults and starved to death, and university associate professors were made into living sculptures in abandoned studios.
A line of blood is left at the scene of each case, corresponding to an ancient original sin.
When Lu Ci, the deputy captain of criminal investigation, was chasing the murderer, he discovered that the serial murderer not only knew his actions well, but was also secretly related to the death of his sister. Su Mian, a criminal psychologist sent by the provincial department, read the chilling truth from the crime scene - there may be more than one murderer.
What is even more disturbing is that the victim in each case has had an intersection with a person codenamed "L". And this "L"'s last email lay quietly in Lu Ci's inbox, with only one sentence written on it:
"You may not remember me. But I remember you."
