In 2125, osteophagia swept across the world like a plague, and flesh and blood rotted and disintegrated amidst invisible erosion. Chen Yan, a 22-year-old neuroengineering researcher, is the loneliest traveler in this disaster - his relatives in the welfare institution have long passed away, and his only mentor Lin Shen fell at the gunpoint of the extremist organization "Human Purity Alliance" in order to protect the "Blue Core" consciousness uploading technology.
Blue nucleus, this superconducting chip cultivated with neural stem cells, holds the hope for human beings to break free from the shackles of flesh and blood, and has become a prey coveted by all forces. Chen Yan, who was infected with osteophagocytosis, had bruises on his left wrist that were spreading day by day, and the countdown to death was tightening amid nerve pain. He must escape with the Blue Core, and amidst the pursuit of the Pure Alliance and the risk of losing control of his technology, he must complete the unfinished experiment of his mentor - to let his consciousness break free from the decaying skin, and in the symbiosis of machinery and flesh and blood, he can open a way for humanity on the verge of extinction.
When the blue core was embedded in his temple, and the light blue data flow was entangled with the dying synapses, Chen Yan became an "alien" between flesh and steel. What he will face is not only the pain of body modification and the crazy siege of the alliance, but also the ultimate torture of "survival" and "authenticity" in the depths of human nature. In this rusty world, can the lone traveler's fire ignite the mechanical dawn?
