As instructed by the police chief, Xiao Luo was to pick three auxiliary policemen to make up his team, and he picked Liu Tieguo, Ye Qiu, and Wang Lihu. He hadn't planned on pulling Liu Tieguo into this, not since he owed Liu Tieguo a favor, and he really did not want to put him in any danger. But in the end, Liu Tieguo insisted, and Xiao Luo couldn't dissuade him from being a part of the team.
As for the other two, Ye Qiu and Wang Lihu were both born troublemakers, and that was well known among the police officers in the station. They had worked for two years, but yet a promotion was nowhere in sight for them. It wasn't because they did not have the necessary skills and experience, but rather because they would often get into trouble.
For instance, they were supposed to mediate a dispute between city patrol officers and melon farmers. Not only did they fail to resolve the conflict, they even sided with the melon farmers and beat up the city patrol officers.
