The Detective's Evening Reasoning

At ten o'clock in the evening, the Criminal Investigation Detachment of the Municipal Bureau. Shen Yuan took off her bloodshot contact lenses and looked at the clueless serial murder case on the whiteboard. She is the only daughter of "Shen's business empire" and has a net worth of hundreds of billions, but she has to remain anonymous to work as a backbreaking detective. Unable to solve the case, she dropped the coffee cup on the table irritably. "Old Zhou, tell me, how did this murderer do it?" Standing behind her was her driver, Lao Zhou. This veteran, who was said to have flown fighter jets in the army, handed over the thermos cup and said calmly: "Miss, please swap the identity information of deceased No. 4 And deceased No. 1, And everything will be clear." Shen Yuan was stunned and turned back to look at the whiteboard. Three seconds later, the entire case collapsed and reorganized in her mind like dominoes. ... This case is solved. This is a story about a "rebellious young lady detective" and a "sweeping monk driver who takes care of her" teaming up to conquer crime.
