Luo Fei checked Guan Er’s violin box and found the powder hidden in the secret compartment. Qin Xiaoman followed Luo Fei to the library to look up information, and found out that whenever the orchestra performed in a certain place, there would be drugs there. After careful analysis, Luo Fei deduced that Xiao Lang’s orchestra was secretly selling drugs.
