After the Great Collapse, the world was reduced to a wasteland shrouded in acid rain and radioactive dust. The surviving humans huddled in the last giant city "New Arc City" - a cyberpunk fortress managed by the supreme AI "Pangu". Here, prosthetic body modification, neural access, and data flow are necessities for survival, while human nature and memory have become commodities that can be traded. However, in the shadow of this jungle of neon lights and steel, the ancient power of Eastern fantasy has not died. The forgotten "runes" and "mantras" resonate with the underlying code of the city in an incredible way, becoming the only taboo power that can challenge the divine power of AI and repair the trauma of the world. The story tells the story of a wasteland boy who makes a living by scavenging and cracking data, and meets a mysterious girl carrying an ancient inheritance. Together, they will uncover the deepest secret of the world: Is the end of technology a new life or another destruction?
