So a couple of things. First, I'm thinking about Gan Guangli and how miserable he must feel when he hears about Renxiang going out on missions like this and him unable to be there fighting to support her. Just the worst! Once he makes it into the inner sect, vibe is going to be so much different in the "Cai Group".
Second, a completely unrelated topic.
It honestly surprises me how little emphasis is put on gathering information about your opponents, or even your allies. Or at least, how little emphasis we've seen on it from Ling Qi's POV. So much of these Cultivator fights isn't just power vs. power, but more a kind of counter and counter-counter where knowing what to expect from your enemies (and for that matter from allies) would be a crucial aid to victory. Knowing exactly what your enemy's arts are and how they are likely to attack you and defend against attacks has got to be worth multiple stages of difference in a hypothetical "you know everything about them and they know nothing about you" fight.
Now of course it's going to be tough to know exactly what sort of powers an enemy people like the Shishigui or the Cloud Nomads are going to bring to the table, but one can imagine briefings that go into stuff like, "Common abilities are X, Y, and Z; whereas A and B are things we've never seen from them. Cloud Nomads with N mount type frequently seem aligned with P type abilities." Etc. An on the other side, while I certainly understand why Young Masters will want to keep their secrets, understanding the abilities of your allies and what they are weak against and what they are strong against would sure be a huge help on a battlefield where split second decisions have to be made.
You can even imagine an entire character concept built around it, the woman who has memorized the details of every art ever observed and recorded and can make a pretty good guess on at least the broad strokes of an enemy's techniques just from seeing a single ability in action. Seems like it could be a big deal!
Of course, maybe circumstances just haven't been right to see that sort of thing in Ling Qi's perception. Still, it would kind of cool if for example, someday we had to join to go after a Cyan foe with a bunch of other Greens and it was proceeded by an extended discussion of everything known about their abilities and specific assignments made as to who is going to try to what to hinder and confuse them and where their likely vulnerabilities are. Just go deep tactical at least once. (I know *players* have sometimes done that for certain duels, most notably the Princess in the Tournament, but it hasn't been as big a part of the narrative.)
I keep going back and forth on whether or not this would be effective. Surprisingly, for all my love of that specific counter it feels like my conclusion is that it'd be misguided in this case.
My first immediate thought was that, in terms of how effective it'd be, this hits a pretty hard ceiling at late Green: that's when people can't take in outside Arts any more, they have to create them all themselves. Even if someone's an Coldstar Blade user from a long line of Coldstar Blade users, they're still going to create their own unique spin on it. You can be pretty sure ice, fire, swords, and duality will be involved, but that conceptual space is only going to get wider and more complicated as they go up the chain, and specific counters will grow less useful.
But then again, once people are past that point, they're in more conceptual territory: they move further from typical human mindsets and into a territory more governed by adherence to specific rules and ideas. So knowing their concepts gives you an idea of where to shiv them in the philosophical and/or literal back.
But my thought after
that was that if you put a big emphasis on always attacking people at their weak points, then they tend to fix them, and finding flaws and fixing them is how you advance in all forms of cultivation. So it feels like implementing that on a large scale--"okay, Red+Yellow Army, these are the Cloud Barbarians, they are weak in these very specific ways"--would, failing genocide, result in enemies that are militarily
and philosophically stronger, because the two are highly intertwined. And given that people are disproportionately stronger at higher levels of cultivation, it strikes me that putting your enemy's army through the crucible makes things worse for you in the long term, not better. It might be useful as something you do very rarely, for very short periods of time, but how much restraint do large organizations typically show with the Tragedy of the Commons?
My thought after
that was that it'd be possible to make an individual Way of it, because if you were sufficiently good then you'd be able to win fights the first or second time so that they didn't have time to temper themselves... But defining yourself by other people in an adversarial sense feels like it'd be a pretty dead-end Way. (Unless you ID the protagonist and you're willing to play Vegeta all your life.) I'm not sure how you'd focus that sort of Way in on yourself instead of others, unless it was tied to some conviction related to breaking the rules of nature and the universe through edge cases, which seems like it'd get you someone from the Ministry of Integrity smiling and asking pointed questions.
