After transmigrating into the body of a silver-haired half-vampire girl, she opens her eyes to find herself lying beside an unfamiliar river.
An old hunter takes her in and gives her a knife. She doesn't know how to use it, but her body remembers.
She doesn't know who she is. Chen Mo? Lyra? Or are neither of those right?
All she wants is somewhere to survive. The Seven Border Cities are being devoured by the undead, and she has a few ways of waging war in her head that don't belong to this world.
Before the river runs red with blood, first figure out who belongs where.
Later, people start calling her the Silver Fox.
"Little lion."
"Don't call me that, silver-haired fox."
"Then don't look at me like that. As if I'm going to steal your bone."
"You are stealing. My soldiers and my food."
"But I'll share half with you."
"...You're crazy."
Two people who can't stand each other fight one battle after another, because they have no choice.
She doesn't want to fight.
But her mind won't let her stop.
