The top assassin Shen Li was once a perfect believer in the "Destiny Trajectory Simulator" and relied on the "optimal solution" deduced by him to complete countless missions without injury. However, a mission targeting top hacker Ling Xiao caused her "golden finger" to completely malfunction! Ling Xiao, a "variable" that cannot be defined by data or captured by the trajectory of fate, has plunged Shen Li into an unprecedented "destiny blind spot." Faced with the organization's pursuit and Ling Xiao's interference, Shen Li was forced to abandon her reliance on the simulator and instead stimulate the "shadow rhythm" hidden deep in her consciousness. She uses her extraordinary perception to understand the rhythm of all things, blends into the environment with extreme stealth, dances with the code with her blade, and transforms into a true "dancer of destiny" in desperate situations. When the "Revisor Council"'s "Clear Plan" surfaced, Shen Li and Ling Xiao, former enemies, had to join forces to fight against the powerful forces behind the scenes that controlled destiny. In the unpredictable blind spot, how will she find herself, fight against her destiny, and reveal the ultimate truth of the world?
