In the near future, memories can be read and stored. Ling Chen is a top memory submariner. He can dive into the sea of other people's broken consciousness and salvage the lost fragments. However, he was unable to retrieve the painful memory of his wife and daughter's car accident, and that blank space became his eternal nightmare. A mysterious commission leads him deep into the consciousness of a deceased technology giant, where the client claims there is a will that could change the world. When Ling Chen dived into the storm-raging sea of memory filled with defense mechanisms, he was shocked to discover that the seemingly isolated island of memory was inextricably linked to his forgotten past. The truth was far more cruel than he imagined.
