In the future Blue Star, a giant mechanical city called "Nova City" rises from the ground. The steel forest reaches into the sky, and neon lights and shadows interweave into the never-ending day. Human beings coexist with highly developed artificial intelligence (AI) and mechanical bodies, and the city itself is a huge and sophisticated living body. However, under this seemingly perfect steel maze, a mysterious "code ghost" began to erode the city's neural network, causing abnormal AI behavior, frequent failures of key systems, and even threatening human survival.
The protagonist Ling Feng, a promising urban system architect, lost part of his memory due to an accident and was implanted with an experimental neural interface, which allowed him to perceive and interpret data flows in a unique way. When his mentor, one of the creators of Nova City's AI core "Source Point", disappeared mysteriously and was accused of being the originator of the "Code Ghost", Ling Feng was forced to embark on the path to pursue the truth.
He wanders between the city's upper-class elite areas and the dangerous lower-level abandoned areas, dealing with loyal AI assistants, mysterious data brokers, and giant corporate forces trying to cover up the truth. Ling Feng not only has to uncover the true face of the "Code Ghost" and retrieve his lost memories, but he also has to face a difficult choice about the future of mankind and AI. In this cold steel maze, can he find the warmth of humanity and prevent a huge crisis that could subvert the entire Blue Star civilization?
