Huang Zhen is a fringe reporter at a newspaper, struggling at work and facing a romantic crisis. At thirty, his life is trapped in the dead end of mediocrity, until an anonymous text message shatters the peace.
A jade pendant patterned with blue scales and an incomplete ancient family genealogy reveal a family secret spanning a thousand years. He never imagined he could be the legendary "living key," bearing a blood curse passed down through generations. The memories sleeping deep in his bloodline conceal a secret powerful enough to overturn his fate.
In a sealed place shrouded in mist, eerie sacrificial rites, secretive clanspeople, and encroaching shadows leave him teetering on the edge of life and death at every turn. As "protection" clashes with "plunder," and "truth" interweaves with "lies," he is forced to struggle in the depths of human nature. Will he become a pawn controlled by others, or break free of the chains of fate?
A thousand years of grudges, an international conspiracy, and a battle of human nature: the ultimate struggle to protect conscience and justice begins the moment he takes hold of the blue-scaled jade. Beneath the blood curse, no one can escape unscathed. And the so-called fate may have had its twist planted a thousand years ago.
