On the twelfth day of the apocalypse, the whole city was engulfed in white fog. The fog people only chased the sound, not the light.
Chen Xu discovered that if you touch the dead person's cell phone, you can play back the last image of him before his death - every cell phone is a way to survive.
"On the twelfth day, go west" "Don't play back the phone again" "Don't let her speak"...
A text message from the future, a mobile phone that always stops at 12:00, a girl whose singing can dispel the fog, and an iron tower in the west of the city that archives living people as "samples."
The more he read, the more he discovered: the fog was not a natural disaster, but was "fed" by someone using signals.
And he is the only one who can play back the truth.
