I, the Classic of Mountains and Seas, Hold a Black Household Registration in Zhenshi

She sent me a voice message the night she disappeared. The last three seconds were screaming. Three years. I found nothing. Until that system bound me - dark red, with rough pixels, like a web game from twenty years ago. It told me that what she shouted in that voice message was not "Help", but "Brother, run quickly." There is a scar on the index finger of my right hand, which was caused by smashing the wall on the day my sister disappeared. Pinch it every morning to make sure you are still looking. The system said she was SSS-level file CY-0731. Said she was the "seventh generation". I was also given a "Zhenshi Household Registration Book". The first person to register was the cashier at the convenience store downstairs who had been feeding cats for twenty years. She said her name was Su Daji. The household registration was canceled three thousand years ago. She asked me what to write in the note. I said, "She's her own." That night I heard three knocks on the other side of the wall - thump, thump, thump. #SystemStream#Myth Reconstruction#Urban Fantasy#Suspense Decryption#Healing#Tearjerker#Single Female Lead#Brain Hole#Contrast Cute#Cthulu#Shuangwen#Knock three times
