Until that morning, a careless jump of the algorithm allowed him to glimpse a perfect murder thousands of miles away - the screen shook, one person fell, and the live broadcast was interrupted.

When he tried to pursue the truth, he found that the murderer had already targeted him through the same random network. A deadly hunt led by algorithms, spanning virtuality and reality, begins. When every push may be a warning of death, the only thing Zhou Ming can rely on is to be one step ahead of the murderer and jump into the next unknown...
