Let's review our options on how we can split the team optimally.
First things first, I am not letting Guo Fu wander alone. The stories of a farmer boy coming into a big city only to be conned out of his last shirt by the first scoundrel he meets are so common, they are almost a cliche. And something tells me that if it happens, the guy would not just meekly stand aside and weep in a corner, but, given his natural talents and a keen sense of justice, will try to restore it, oblivious to the fact that he will find none in this town. The big guy is staying with us, both for his good and ours.
Next, Wu brothers are a natural choice for another team. They know each other well, they are accustomed to teamwork, and so they can be trusted to watch each other's backs. Taking them with us seems like a waste, though. They do not add insight to our group, nor do they pack too much of a punch. They are a good choice to cover more ground. Splitting them further than that would be stretching our forces too thin, as one of them would have to wander the city by himself, or with Bai Juitian that they all come to dislike, neither of which is great.
Finally, Bai Juitian. I have to admit, I find it disturbing how
complacent cooperative the guy have become in a matter of minutes, considering both our standing with his sect and with him personally. This is a far cry from a man that had challenged us, wounded, to a duel that would put our life at stake, yet claimed it to be a non-lethal match. I can presume that he was manipulated into issuing this challenge by a third party, the same one that provided him with a healing powder he so conveniently happened to have on him at the time. Still, I am wary of him. Keep your friends close, and your enemise closer, as they say. Which is why I would designate him to the same team with Jing and Guo Fu. It maintains a nice balance between brute force (BJ&GF), smarts (BJ&XJ), and morale (Guo Fu will support Jing, whatever we choose, so we should be in control of the situation).
Of course, Bai Jiutian can form a one-man team on his own, but that would require you to trust him to do his own thing, which I am reluctant to do yet. Pairing him with Wu brothers seems unnecessary, and bad for the morale of all involved.
Two to three teams seem optimal to me.
Now we just have to decide where to send them. I would not send the brothers to the brothel, nor to the bandits. These seem like bad ideas. I didn't notice much diplomatic talents in any of them, so that excludes the Manor, and probably the beggars, too. The market and the tavern seem like a good bet. They can look at the wares and collect rumors as well as anybody else.
If we want to make Bai Jiutian a separate team, I would probably send him to the brothel. Not only for shits and giggles, but he is a natural charmer, he is the one with the money, and maybe getting laid will loosen the stick that is stuck in his ass.
I am not sure what I would like to do myself, though.
Edit: All right.
A1,5 - Jing & Fu & Jiutian to the Manor, brothers to the tavern.
Failing that, I choose what
The Brazilian Slaughter did and switch Fu to the Wu brothers team.
I wouldn't worry about splitting our group, as long as we are reasonable about it. Wu brothers are the best young disciples from the most powerful orthodox sect in all of China. They can handle themselves. As for the trio of BJ&XJ&GF, they are, basically, unstoppable.
I am hesitant to pair just Jing and Juitian, though, without Guo Fu as a buffer between them. Should irreconcilable differences in opinions arise, what are you going to do? Should Bai Juitan decide that he knows better how to handle the case, how are you going to convince him otherwise? It is better to maintain 2 against 1 ratio in such matters, and Guo Fu is the only one that has somewhat normal relationship with Young Master Bai - that increases the chance that Jiutian would actually listen to him.
