Zi Shi Didn't Speak

The rules of the city: Anyone who speaks at midnight will be silenced on the spot. Chen Sangeng, a watchman at the bottom, can hear the last words of the deceased from the watcher's voice - at the cost of forgetting a memory every time he hears it, up to a limit of forty-nine times. Others spell golden fingers, but his golden fingers are like a noose. The voice that called his name at midnight was neither living nor dead... When the time comes, does he still dare not to speak?
