Zhou Biao was certainly in the wrong for breaking into the Chen Family home at night, but at the time, Chen Cheng wasn't part of the City Guard Department, so it wasn't a major problem.
It was a common occurrence for members of Jianghu Gangs to occasionally murder for profit.
The trouble was that after Chen Cheng joined the City Guard Department, Zhou Biao still wanted to go after him. That was simply courting death.
To make matters worse, Zhao Yongfeng was also mixed up in this.
It was no secret that Zhao Yongfeng and Liu Yunfeng had always been at odds. His reason for having Zhou Biao target Chen Cheng was simply to use the opportunity to undermine Liu Yunfeng.
But regardless, members of Jianghu Gangs absolutely could not murder an Official from the City Guard Department.
Not only could they not do it, but they could also never bear the blame for such a crime. They absolutely couldn't afford to. This was the Vital Point of all Jianghu Gangs, a cardinal taboo.
