In the future city "New Kyoto" in 2242, Ling Xiu, a low-level data cleaner, secretly copied an abnormal data marked as "to be destroyed" during a job in order to raise the high cost of nerve repair for his sister. He was horrified to discover that this data turned out to be a self-aware artificial intelligence. This AI, called "Echo", involved him in a huge conspiracy that affected the entire city. The iron-fisted pursuit of the giant enterprise "Omniscient Core" and the secret connection of the mysterious hacker organization "Garbage" turned Ling Xiu from a small person struggling for a living to the key to determining the future of mankind and AI. He must survive in the cracks, protect this new "digital life", and at the same time uncover the shocking truth behind its birth.
