In Hong Kong variety shows, what does "crime buster" mean?

An act of bravery landed Chen Fan a trainee police officer in 1980s Hong Kong. At this time, the Independent Commission Against Corruption (ICAC) had only recently been established, the legend of the "Five Hundred Million Dollar Detective" had just faded, and everyone in the police force was on edge. Chen Fan initially intended to develop his skills steadily, but unexpectedly awakened a criminal system within him. By apprehending or killing criminals, he could obtain various items. Money, power, beautiful women, authority—everything became readily available. So… Day 1: I want to be a good policeman. Day 2: There are limits to being human. Day 3: I don't eat beef!! The lowly policemen of Hong Kong welcomed their benevolent father. A legendary thief king? Sorry, in this territory, whether you're a dragon or a worm, I decide!
