After struggling for three years in a world overrun by zombies, Chi Le accidentally finds a rusted pocket watch. From then on, she gains the ability to transmigrate between parallel worlds once every 72 hours.
One world is hell. The other is paradise.
In the apocalypse, she is a lone wolf willing to risk her life for a single supply. Here, she becomes Chi Yue, a college student who still has group assignments to turn in.
The three-day countdown keeps her alive.
With her left hand, she digs gold bars and antiques out of the ruins. With her right, she ransacks the supermarket.
In the morning, she struggles to stay awake in class. In the afternoon, she trades goods for medicine and maps in the city.
Until Yi Sa, the annoying guy who always watches her with a half-smile, accidentally grabs her hand just as she transmigrates at the last possible moment.
"Chi Yue, why do you smell... like blood?"
Before he can finish speaking, the world spins around them.
When he opens his eyes again, the setting sun is blood-red, the air reeks of decay, and zombie groans draw closer from every direction.
The pampered young master turns deathly pale, while Chi Le has already drawn her dagger, her gaze cold as ice.
"Welcome to my world, Young Master Yi."
"Here, staying alive is the only rule."
Later...
When they fight back-to-back in a ruined city,
when he takes a lethal blow for her, his once-expensive shirt stained red with blood,
when the countdown reaches zero again, yet he still doesn't release her hand.
Yi Sa wipes the blood from the corner of his mouth and grins recklessly. "Chi Le, can that busted watch of yours... bring a plus-one?"
