In the future, quantum computing and consciousness digitization technology will be highly developed, and humans will be able to transform literature, film and television, and animation works into "data corridors" that can be immersed in experiences. The protagonist Ling Xia is a "corridor restorer". Her consciousness can penetrate the data barrier and enter the world of works that are logically disordered due to the audience's strong "regret emotion". In these worlds, those characters that make readers feel uncomfortable (such as scientists who died unjustly, misunderstood reformers, and self-sacrificial guardians) are trapped in a "regret closed loop", constantly repeating tragic endings, and even causing the data of the entire work to collapse.
Ling Xia's mission is to enter these worlds with "logical anchors" and use non-emotional intervention methods (such as providing key information, repairing technical loopholes, and revealing hidden truths) to break the characters' tragic fate and allow them to move to a more reasonable ending according to their own will, thereby repairing the corridor data. Her tool is a "sequencer" that can analyze the rules of the world. It can access the background information of the work to a limited extent, but excessive intervention will trigger a "data storm" and endanger her own consciousness.
