This carries on right from where Xiao Xiao 7 ended, and ends itself with a big "To Be Continued" at the end. Unfortunately, this looks like the last of that particular series of movies as the rest of the Xiao Xiao series is not related to this.
It's a shame as this was a good episode, with some impressive looking visuals that was let down by its lack of resolution and mostly, its lack of action. Apart from the scene at the start and the scene where the man gets hit by the van, most of this entry was just driving. Long drawn out scenes of driving. And talking on the phone to set up an ambush. And then more driving. How fun.
This seems like it was more of a filler episode between the badassness of Xiao Xiao 7 and whatever was to follow in the sequel to this. It seems like a way of drawing out the story by moving locations after just having the Kingpin locked down. Thats why it doesn't work so well here with no followup to it - its actually mostly boring.
Come back from deepest darkest China and finish this series of movies! :D
