Forensic assistant Ling Che was on the verge of death due to an explosion, but was accidentally bound to the "Crime Insight System" from the future. This golden finger gives him a terrifying ability: he can "recreate" the crime scene from a first-person perspective, experience the victim's despair, and gain insight into the murderer's thinking trajectory. Tianqiong City, this smart city under the light of science and technology, is being shrouded in the shadow of high-intelligence and high-tech crimes. The serial killer codenamed "Shadow Dancer" comes and goes without a trace, leaving no trace at the scene, and traditional police forces are helpless. Ling Che relied on the system to break through the fog many times, but he also suffered mental shock and moral torture. With the upgrade of the system and the unlocking of "criminal psychology traceability" and "future crime early warning", he can not only gain insight into the deep motivations of criminals, but also foresee future bloody crises. When he is targeted by a more powerful awakened force, can he stick to his true heart and become the salvation of Sky City in the shadow puzzle where technology and supernatural powers are intertwined?
