Let's do a quick review of Choices&Consequences
A.
+ We gain fame and a lot of attention. Defeating 4 of the Heroic Youths alone is no mean feat.
+ We defeat 4 of our marks for the purposes of Zhang's mission
+ We get a first-hand experience of what Taishan Sect is capable of.
- Attention is a dual-edged sword. We will probably lose our 'merchant noob' identity.
- Too much risk. This is a team game, and 4-on-1 are not good odds. If we lose personally, we might fail our team, too, since we are one of their best fighters, along with Murong Yandi.
-
treave just mentioned that they also have a technique relying on Pressure Points. It is meant to be performed by 7 people, but so is Qixing Beitou Formation. Even if we succeed, we risk revealing our invulnerability to this attack type to everyone present.
B.
+ We avoid attention and keep to the shadows.
+ We get to observe, though not experience, the techniques of both Yandi and Taishan sect.
- Too much risk. This is a team game, and 4-on-1 are not good odds. If Yandi loses, we might fail as a team. Yandi have shown us that he is good at defense, but his offensive capabilities are yet unknown.
C.
+ We trounce them with minimal effort. Jing and Yandi can hold them off by themselves, but together they can finally go on the offensive.
+ The attention would be split between us and Yandi. We might be able to explain our victory away by letting him take all the credit. Something tells me that he is going to do so anyway.
- We won't gain much information or fame for this action, but we get to progress further.
D.
+ Teambuilding. Our team can use some.
+ Guo Fu gets his chance to shine.
+ We avoid attention and keep to the shadows.
- Our team coordination is far worse than those of our opponent's. We might hamper each other's efforts.
Of these, C seems the safest bet. I am not too concerned with laying low, so I like the sound of A, fame-wise, but it carries too much risk (since the Pressure Points immunity is one of our top secrets), and its other benefits are debatable. Yes, we defeat 4 of Heroic Youths, but does it mean they won't fight us if we challenge the other 3? They act like a unit, afrer all. Then again, if it does, it sounds like a good way to split them. But nah, too much uncertainity.
Edit: and
treave pretty much confirmed that we'll have to defeat all 7 of them at once anyway.
