Sixty years ago, a cataclysm forever altered the human world. Species evolved at an unprecedented pace, forcing humanity to retreat behind towering walls in a desperate bid for survival. Three years ago, Gu Chen's father mysteriously disappeared, branded as a traitor to humankind. His younger sister was infected with a deadly virus, transforming her into a blood-dependent "Infected," a pariah hunted by society. Abandoned and cast aside, the siblings struggle to survive in the slums, a place rife with violence and crime, where their lives seem trapped in endless darkness.
However, when an unexpected lockdown exposes his sister's identity, her life is thrust into imminent danger. To protect her, Gu Chen is forced to stain his hands with blood, embarking on a path fraught with peril and harrowing choices. In a world where tyranny and chaos coexist, Gu Chen leads a double life. By day, he is a respected coroner, uncovering the grim truths behind deaths and shedding light on hidden darkness. By night, he becomes a secret guardian, standing in the shadows alongside his sister, fighting against their merciless fate.
In this era steeped in violence, greed, and corruption, survival demands cold determination. The hidden conspiracies and the inescapable burden of their identities are both their driving force and their greatest shackles. This is a relentless struggle for survival, a profound test of family, faith, and courage.
