In order to save his sister Lina, whose memory is constantly crumbling, Memory Weaver Kane accepted a dangerous commission from Silas, an executive of the Forever Memory Group: to repair a broken memory called the "Original Code" from the beginning of the "Grey Mist". During the repair process, Kane discovered that this memory was not accidentally damaged, but was artificially encrypted and torn. He gradually became involved in the secret war between the Yongyi Group and the Silent Whisperers, and uncovered the shocking secret of the gray fog - it is not a natural phenomenon, but an out-of-control weapon designed to erase a specific history. Kane's ultimate goal changes from saving his sister to choosing between "false peace" and "painful truth" and deciding the future of the entire Isham.
