"Cruel Underworld" is an excellent novel that thinks about human nature and explores society. It records the entire process of a very small number of people accumulating wealth through criminal means during China's transformation period and eventually leading to destruction. The tragedy of a "ruthless" character's self-destructive life is presented in a realistic style. In the 1980s, Zhong Tielong, who came from a poor family, was admitted to the mathematics department of a key university, but after graduation, he went astray step by step. With their ruthless power, by the turn of the millennium, Zhong Tielong and his subordinates had become an unstable factor disrupting the normal order of Changyi City. After repeatedly violating the bottom line, Captain Chen of the Criminal Investigation Brigade vowed to arrest him and bring him to justice. Rise and fall in an instant. The work still has important practical significance for today's society and has profound enlightenment and warning effects. It is a classic worth reading.
