[] The future changes with every step, never be certain you know what is coming
This is an insight based around the future being not 100% certain until the moment it becomes the present, and probably insures Ling Qi will always have an element of self doubt. Also I don't think it really has much to do with heart demons as that seems more like Ling Qi wants her cake, and wishes to eat it, but regardless this fits well with her other insights at a quick glance.
[] To journey and seek knowledge is virtue unto itself
Huh I'm... honestly alright with this insight.
This is an insight for one who wishes to seek out the tribes within the Wall to learn their culture, and traditions. Now working that into the duties given to CRX, whatever LQ's fief requires, and other unknowns will be difficult, but not impossible imo.
This would build off of Ling Qi's desire to reduce casualties seeing as seen in the Yuan He interlude even a prisim cannot protect the world, and thus seeking out knowledge to understand the other side to avoid conflict seems like an approach to doing so. Like it won't matter for the current conflict unless it drags on for centuries, but if/when Shenhua wins an actual understanding of at least some of the CN culture seems like it would be useful saving lives that while not particularly important in the grand scheme of things seems rather important to LQ herself.
Also it is very much so biting the bullet, and including a hard virtue into Ling Qi's Way, which if you want one is probably best to do sooner rather than later as the trend for Shenhua's expectations are "past results become the new minimum threshold for success". This seems like an external pressure that can incrementally leading to your Way being built around your job/duty.
