The Unlicensed Detective's Path to Breaking the Case

Wu Heng is an unlicensed detective who relies on his keen observation and reasoning skills to solve various difficult cases in the shadows of the city. However, long-term high-pressure work and inner loneliness gradually eroded his spiritual world. In the process of investigating a case, Wu Heng was on the verge of mental collapse and split into a personality named "1". "1" Is cold, rational, and possesses extraordinary insight and calculation ability. He seems to be Wu Heng's other self deep in his heart. Whenever Wu Heng is in trouble, "1" will appear to help him solve the puzzle and even predict the murderer's next move. However, the appearance of "1" also brought new problems: Wu Heng began to be unable to distinguish reality from illusion, and even doubted whether "1" really existed, or whether he himself was just a shadow of "1".
