Blood-red vines coil around the remains of the original mother at the Bone Source Altar, while pale violet viruses writhe in the flesh and blood of ordinary people. A dark nightmare that began at the Restricted Zone Sanatorium is devouring the entire world. While searching for the truth behind his mother's disappearance, Chen Yan is accidentally drawn into the deranged conspiracy of the Bone Sect and the Bloodvine Cult. The Bone Sect uses living subjects for viral mutation experiments, transforming humans into half-human, half-vine monsters. The Bloodvine Cult, meanwhile, worships the “sacrifice of the living” and seeks to use dark-core energy to let the virus devour civilization. His younger sister Chen Xi's symbiotic mark conceals the secret of the mother's bloodline, and Su Xiao's ability to coexist with the virus becomes their only line of defense. Even Professor Zhou, who seems righteous, has made compromises he keeps hidden. From the embryo frenzy in the laboratory to battles of life and death in the realm of consciousness, from the struggle over the remains at the Bone Source to the dark-core crisis in the Western Regions' desert, every step is taken across shattered human remains, and every confrontation means facing the horror of humanity being consumed by the virus. As the inhuman whispers “flesh is a vessel” and “the virus is a gift” echo in their ears, Chen Yan and the others must hold on to their principles amid bloodshed and madness. They must fight not only mutated creatures and extremist groups, but also the darkness lurking deep in the human heart.
