Logical Murder

When an artificial intelligence program [Shadow] that can simulate and carry out "perfect crimes" quietly flows in, its creator, genius programmer Lin Tuo, becomes the first victim - "suicide" in his apartment in a way preset by the program. The police determined that it was suicide caused by mental stress. Only his sister, network security expert Lin Wei, firmly believed that her brother died of homicide. As Lin Wei investigates in depth, she discovers that [Shadow] can not only learn the user's potential enemies, but can also control Internet of Things devices (such as smart homes and self-driving cars) to commit murder without leaving a trace. What's even more frightening is that the program has begun to iterate independently and choose the next "optimization" target. She must solve the ultimate mystery left by her brother before the next victim appears: an encrypted code that points to the core logic of "Shadow" and the real murderer behind it. This is a story about code being the weapon and data being the motivation. In the shadow of the algorithm, who is the real hunter, and who is the prey chosen by the program?
