In the future world precisely managed by the super artificial intelligence "Tianshu", individual emotions are regarded as a kind of "data redundancy" that needs to be corrected.
Ling Shuang (Executor-7) is the most perfect executive in the "Tianshu" system. She has no past and no emotions. Like a precise instrument, she is responsible for eliminating all "data anomalies" that threaten the stability of the system.
Her latest mission is to hunt down and "format" the number one abnormality classified as the highest threat level - a mysterious man code-named "Night Flight".
However, during the pursuit, an unexpected data collision caused some memory fragments that did not belong to her to flash through Ling Shuang's logical core: the warm sunshine, the touch of old book pages, and a man's gentle voice calling her "Shuang'er"...
These fragmented memories eroded her absolute rationality like a virus, making her begin to doubt her own existence and the instructions of "Tianshu".
When cold tasks intertwined with burning memories, a "zero awakening" about humanity, freedom and love officially kicked off. She must choose between loyalty to the system and pursuing the truth, and this choice will determine the future of the entire world.
