but that isnt the only lesson she has learned. One bit that striking forward can bank on, is on having confidence in her allies abilities (like what she did with Zhengui).
You cant really say any of the choices are "worse" fit for her, you just have to decide what she would grow into from this choice.
Specifically in terms of the baggage from the Forest King dream, I can 100% confidently say charging the enemy is
objectively worse in narrative terms. It creates a further muddling of an already tangled messy bundle of trouble, without any real contribution of value to it. Just self-contradiction and probably self-loathing later on.
You're right that Ling Qi has learned other lessons since, and I wouldn't have immediately jumped to the Forest King/Bloody Moon connection in relation to this event
except that Ling Qi has already strongly evoked it. It's actively in play in the scene and its development, in a way nothing else has been emphasized. The idea that it won't be a significant dimension of character progression or meaning of choice in the event doesn't hold water in the context of its prominence in the scene already. That being any at all versus the total lack for anything else. I don't expect it to be the
only factor, but it can't not be a primary factor, in terms of narrative continuity.
The other thing is her various other philosophies probably more ably align with
Let them come? Like her TRF insight, or advanced insight, or even SCS insight for the plan's dynamism. FVM seems valid at first glance, but the fact that charging the enemy takes on relative risk on behalf of the people we're supposed to defend undermines it, and FSS's doesn't seem applicable outside of keeping determination in the face of setbacks, which is neutral. She learns non-insight lessons too, but those are the easiest to hit(and remember).
Specifically on the matter of having confidence in her allies abilities, you can criticize both paths. With one, she's trusting her allies to not die, yes, but taking on the burden of fighting half the force by herself. With the other, she's dedicating herself to their protection, yes, but is also acting on the premise that their power wedded to her own is important and potent enough to be her primary goal in resolving the conflict favorably. She's gotten a bit snobby about other cultivators, so that isn't a small thing.
