In the "new pulse" of the future city where neon lights flash and information flows, Lin Mo is an amnesiac and lives a mechanical life. One day, he accidentally got a strange metal cube. At the moment of contact, unfamiliar memory fragments flooded into his mind - cutting-edge technology, secret meetings, and a face that he felt familiar but could not remember. These "echo fragments" do not belong to him, but they are extremely real. He realizes that his memory may not have been lost, but was deliberately deprived and replaced. In order to find his true identity, Lin Mo entered the underground black market of memory trading, only to find that he was being tracked by a huge and dangerous force. The journey to retrieve the past has already staked his future.
