In 2035, the holographic online game "Abyssal Era" swept the world, and real crimes resonated strangely with virtual data. The sunny and cheerful college student Gu Chengze accidentally awakens the "data backtracking" golden finger, which allows him to enter the virtual reconstruction space of the crime scene and capture the erased fragments of the truth. Gu Chengze, who appears to be an ordinary player, is actually a "virtual profiler" specially hired by the police. When a serial killer uses game mechanics to create a perfect secret room in reality, Gu Chengze shuttles between the neon-lit cyber city and the crisis-ridden virtual copy, breaking down the criminals' psychological defenses with his sunny smile. However, all clues point to a man behind the scenes hidden deep in the code - the "architect", who is planning the ultimate crime that combines reality and reality. Gu Chengze must uncover layers of fog within a high-energy text of 80,000 words, and use wisdom and courage to end this cross-dimensional cat-and-mouse game.
