Rules descend, and the world becomes a hunting ground for eerie tales.
Chen Mo can see the gray annotations behind every rule. He thinks he's found the cheat sheet for clearing the game.
Until he discovers a line of text on the back of a photograph:
[One of today's annotations is false. Find it, or you'll be dead by morning.]
The countdown to death in the supermarket's freezer section, the weeping ghost in the elevator's mirrored side, the rules that appear on their own and predict the future... The "answer key" he depends on to survive is dragging him into the abyss.
When the official search team comes after him, and his companions risk their lives for him in the mirror world, Chen Mo finally understands:
These eyes are not a gift. They are a mark.
He is changing from someone who solves rules into the rules themselves.
And the only way to break the deadlock is to find the seven rule nodes,
then shut them down one by one with his own hands.
