In the new arc city where neon lights and acid rain intersect, the tentacles of technology extend to every corner of human consciousness. Ling Xi, a promising "memory stalker", is now a private investigator who can only take on small jobs on the edge of the city. His specialty is diving into other people's memories to find forgotten truths. A bizarre commission broke his decadent daily life: a mysterious woman named Nighteye claimed that her memory had been erased for a week precisely, and the blank space in this memory was like an ever-expanding black hole, beginning to swallow up her perception of reality. After Ling Xi sneaked into Ye Tong's consciousness, he discovered that the memory area was not blank, but a piece of scorched earth burned by malicious code, hiding a shocking secret that could plunge the entire city into chaos. This is not only a pursuit of memory, but also a fatal game on the boundary between reality and illusion, humanity and technology.
