Hong Kong Police Internal Affairs: I Track Down the Iron-Blooded Inspector of the Fourth Detective

In 1962, the British Hong Kong Police Force was in its darkest heyday. Only the protagonist enters the most unpopular, offending, and most special power [Police Internal Affairs Division]. He doesn't catch street thieves, he doesn't get involved in club disputes, and he doesn't curry favor with the four detectives. Only do one thing: investigate the police team, investigate the criminal police, investigate the fee chain, investigate the four private frauds, and investigate foreigners for harboring corruption. The contrast between the times: In troubled times where everyone is collaborating, the protagonist uses "system rules" as a knife, does not involve gangs or corruption, and specializes in attacking the deep-rooted cancer of the police force in the 1960s. He is the first iron-blooded police king in Hong Kong history to overturn the four detectives pattern with police compliance.
