It is a science fiction masterpiece that combines elements of cyberpunk and Eastern immortality. The protagonist, Chen Xing, was originally a low-level scavenger in the New Demon City. He accidentally swallowed the "Taotie", a soldier-level prosthetic body with the ability to devour and evolve, and was involved in the life-and-death game between the scavenger alliance and the mysterious sect. In order to control his mutating right arm, he was forced to join the Scrap Iron Gang. He became famous in the first battle of the Kowloon Walled City. He also sneaked into the "Medicine Man Training Base" outside the sect and uncovered a terrifying conspiracy of living people to make "human elixir prosthetics".
As Taotie devoured various prosthetic bodies and gained supernormal abilities such as teleportation and poisonous fog, Chen Xing encountered a double crisis: he was a "living weapon" competed by various forces, and he also faced the mental tear caused by the backlash of Taotie's consciousness. The black market queen Red Scorpion's distant warning and the alchemist's exploration of the origin of the prosthetic body make the truth even more confusing. When the sect launches the "Return of Ten Thousand Souls" plan in an attempt to devour the consciousness of the entire city, Chen Xing must make a choice between preserving himself and detonating Taotie energy to destroy the conspiracy - this ultimate experiment of human-machine symbiosis may completely rewrite the evolutionary laws of cyber cultivation.
