In the super city "New Ark" of the 22nd century, under the cold steel sky, human taste has been unified by synthetic nutritional paste.
He is K, the top executive of the Eternal Dynamics Group, a perfect prosthetic body composed of metal, code and killing.
He is Ling, the chef at the last "late night canteen" in Diyuan Old Street, an ordinary person who protects the fireworks of the world with fire, ingredients and warmth.
An unexpected energy resonance forcibly swapped the souls of the two worlds.
When the soul of a chef lives in a killing machine, can he use the wisdom of a spatula to dance on the tip of the knife and preserve his humanity in the whirlpool of conspiracy?
When the killer's soul is trapped in the mortal body, can he find the long-lost pain, hunger and heartbeat in the reality of daily necessities?
This is a journey of dislocation between body and soul. Ling must control a priceless prosthetic body against a vast empire that seeks to use code to control human tastes and thoughts. And K, on the most primitive streets and alleys, uses a fragile body of flesh and blood to protect the warmth he has never had.
When the code encounters the power of the sword, and when the prosthetic body tastes the taste of fireworks, they will jointly reveal a secret that can subvert the entire era, and finally answer the ultimate question: Is it the body or the soul that defines us?
