Killing One-Eyed Wolf meant thoroughly dissolving the gang in Nan City, but Yun Jian had never thought to expand her forces to said city—not now, at least.
Nan City's economic development was weaker in comparison to Zhe Province and Zhe Province alone was enough on Yun Jian's plate, so she currently was not planning to expand her influence.
That said, Yun Jian's ultimate goal for Falcon Hall was not limited to Zhe Province.
Yun Jian contacted Duan Lei after that and had him take care of the corpses of One-Eyed Wolf and the others. After all, these people were felons who sold human organs. There were more than thousands of families that were broken apart due to them when Duan Lei tabulated the aftermath!
For the crime that One-Eyed Wolf and his men did, they would be sentenced to death too if they were taken to the police alive. Nonetheless, Yun Jian could not be simply killing them either, even if they would be given the death sentence by the police.
