Lin Yue, chief consultant to the Gatekeepers, an elite international law enforcement organization, is ambushed while investigating a cold case involving players around the world. When he wakes up again, he has been reborn as an ordinary high school student who failed his college entrance exams, and forcibly bound to Oracle Era, a newly launched virtual reality game. Stranger still, the bizarre murders appearing in the game bear an uncanny resemblance to the case he investigated in his previous life. His talent isn’t combat: it lets him see “criminal profiles” in the game world. The backstories and motives of every NPC and player, along with hidden clues, appear before his eyes as visualized text and probabilities.
