Chen Ji's instincts were seemingly correct, but unfortunately, it only led to him tripping up. It was just a big fan of Xiaoxi. It really seems his reputation is good enough to at least warrant a delay in the assassination of Xiaoxi. And for him to intimidate his own handler into not letting anyone touch her is interesting.
Wen Jie's become extremely suspicious of him though, and that's definitely going to be a hinder to him getting to Xiaoxi.
