Invisible String

My mother died tragically, leaving only a watch that stopped at 3:17 and a strange black snake symbol - you thought it was an ordinary murder until you discovered that your beloved former FBI father had personally destroyed key evidence! The Black Snake Society relies on antique smuggling to launder money, and uses the logic of the Enigma cipher machine to set up a trap. The truth that the founder faked his death a hundred years ago is inextricably linked to the secret compartment of my ancestral home. And you, in order to find out the truth about your mother's murder, step by step into the shocking scam set by your great-grandfather. The antique desk used in the secret room murder case, the modified pen used in the poison murder case, the secret warehouse behind the church password lock... The clues of the six serial cases all point to the same taboo - is my family an "accomplice" of the Black Snake Society? His father's pen is both a murder weapon and a code carrier, his mother's diary contains holographic warnings, and even the retired police detective's instructions are full of temptations. When the time code of 3:17 was cracked and the prototype of the time travel device surfaced, I realized that the so-called "invisible string" was tied to a perfect crime that spanned half a century, and at the same time was tied to the unexplainable life-and-death game between my father and me. Truth or family affection, you can only choose one!
