The blood-colored vines on the altar of the Bone Origin are entangled with the remains of the original mother, and the lavender virus is crawling in the flesh and blood of civilians - a dark nightmare that started in the "Forbidden Sanatorium" is devouring the entire world. In order to find out the truth about his mother's disappearance, Chen Yan accidentally got involved in the crazy conspiracy of the Bone Sect and the Blood Vine Sect: the Bone Sect used living bodies to conduct virus distortion experiments, transforming humans into half-human, half-vine monsters; the Blood Vine Sect even believed in "sacrifice of living people" and tried to use dark core energy to let the virus devour civilization. The companion mark of sister Chen Xi hides the secret of her mother's bloodline. Su Xiao's virus symbiosis ability has become the only line of defense. Professor Zhou, who seems to be just, actually has an unknown compromise behind his back. From the embryo frenzy in the laboratory to the life-and-death game in the consciousness space, from the fight for the remains in the bone source to the dark nuclear crisis in the sand sea of the Western Regions, every step involves broken human tissue, and every confrontation faces the horror of humanity being swallowed by the virus. When the anti-human whispers of "flesh and blood are containers" and "viruses are gifts" echo in their ears, Chen Yan and others must stick to the bottom line in the blood and madness - they have to fight not only aberrations and extremist organizations, but also the darkness hidden deep in the human heart.
