Lin Ling has a secret: she can slip inside other people's spatial rings.
In an apocalypse overrun by the uncanny and riddled with forbidden zones, she becomes the ultimate stowaway, hiding in the spatial rings of powerful people.
Until she slips into the ring of Ye Ran, a top wasteland hunter, and finds it packed with strange spoils: a singing skull, a diary that oozes black blood, and a faded employee badge bearing the name “Lin Ling.”
Worse still, Ye Ran seems to know she's in there. Before entering a dangerous forbidden zone, he deliberately taps the ring's inner wall. “Little mouse, time to pay your rent.”
Forced to go from a master of keeping her head down to the ultimate support, Lin Ling uses her uncanny perspective to help him crack the rules of death.
When the two venture deep into the S-rank forbidden zone known as the “Flesh Factory,” Lin Ling sees countless sleeping copies of herself in a giant cultivation tank, while Ye Ran points his gun at her “original.” “Now tell me your real name.”
