In the "Cyber New City", a giant city with highly advanced technology in the future, memory is no longer a private wealth, but a data stream that can be edited, deleted or even implanted. Ling Shuo, a top "memory coder", has become famous in the industry of repairing or optimizing memories for customers with his extraordinary technology and calm and rigorous attitude. However, during a "memory reconstruction" task for an upper-level client, he accidentally discovered a "void memory fragment" that had been deliberately erased but strangely retained. This fragment pointed to a mysterious woman named Liu Yi. As Ling Shuo investigates further, he discovers that Liu Yi's past is closely related to the secret research of a huge technology giant, the "Eternal Heart Group", and this tampered memory is actually the key to subverting the order of Cyber City and even rewriting human cognitive freedom. Ling Shuo and Liu Yi are drawn into a life-and-death vortex surrounding memory and truth. They must reveal the shocking conspiracy of the "Eternal Heart" and regain the free will that belongs to all mankind before their memories are completely swallowed up.
