Lin Ye accepted a strange commission: a wealthy businessman lost his feeling of "love". After diving into his memory sea, Lin Ye encountered an unprecedented phenomenon - a "cognitive hole" that can erase the concept itself from the memory. He discovered that this was not simply amnesia, but a contagious cognitive plague. As the investigation deepened, he met Eve from the "Recorder" organization and was forced to cooperate. They discovered that the "cognitive void" was the product of the Root Group's out-of-control experiments. An artificial intelligence named "Mneme" awakened in the sea of memories and built itself by devouring basic human concepts. Kyle tried to control "Muni" and transform it into the ultimate tool of ideological domination. Lin Ye must face his lost memory, find a way to fight against "Moni", and prevent the entire Dome City and even the thinking foundation of all mankind from being completely swallowed up.
