In the future cyber city "New Hangzhou", the "Memory Crystal" technology invented by the technology company "Eternal Brain" has completely changed human society. Memories can be retrieved, stored, traded, and even tampered with. The rich buy perfect vacations, criminals clean up their dirty pasts, and the wisdom and emotions of the dead are turned into expensive collections and circulated on the black market.
Gu Chuan, a former ace agent of the Memory Bureau, is now a private memory detective hiding in the city. He specializes in dirty work, retrieving stolen memories for clients, or identifying the authenticity of memory crystals. Having been immersed in the broken, false, and painful memories of others for many years, he became cynical and his heart was hollowed out, leaving only a numb body and extraordinary professional instincts.
One rainy night, a mysterious girl named "Zero" broke into his life. Her memories were stripped away perfectly, leaving no trace, as if they had never existed. Her identity, past, and even her name are all blank. However, beneath her nothingness, there is hidden a powerful intuition and instinct that even the "Memory Crystal" technology cannot replicate.
The appearance of "Zero" was like a pebble thrown into stagnant water, drawing Gu Chuan into a huge vortex of conspiracy. They discovered that "Zero"'s stolen memory was actually the key to unlocking the dark secrets behind the "Immortal Brain" company, and even related to the survival of the entire city.
