"She's a jian," Magnus says, promptly, with an expression on his face like he's puzzling out the differences in techniques. "Double-edged, and can accommodate one- or two-handed fighting. No shields, traditionally. And yours is a longsword, which can also accommodate one- or two-handed fighting, but the shortest longswords are generally still longer than the longest jian. I think maybe that's part of the difference. Even though Bichen is pretty long for a jian, I bet when you train with one there's an expectation of closer quarters than training with a longsword. And both of those are different from Norse swords like Jack... like, Norse swords are still double-edged... and a little longer than most jian, but still in the same blade-length ballpark... but they're specifically meant to be used with a round shield and against non-sword weapons like axes. Longswords and jian both can be used in more ways than most," with a strong emphasis, "Viking swords, because most Viking swords aren't the strongest sword in the world and can't fly themselves around." He's definitely making direct eye contact (hilt contact?) with Jack as he says this, but then he blinks and looks away, as if something new has occurred to him.

"Hanguang-jun, was the backflip a way of building space in close combat? ...when you're fighting other cultivators, does that open you up to attacks that you can't block, or does it serve as a kind of block because you're moving so fast? Does it even work? I think Lancelot could probably interrupt one next time, and it would probably knock you off-balance." It's a very Magnus-Chase-during-Battle-Practice-type move, which is to say it's not very economical of movement, and sometimes someone might drop a chunk of masonry on your head halfway through if you're not careful about it.
