It's something that has helped save peoples' lives countless times before, after all, of course he'll continue being suspicious so long as the need for it arises. He tilts his head sideways, patiently waiting to see if the stranger continues speaking despite not being understood, but he stops, holds up a finger instead, prompting Sizhui to tighten his own mouth a little more. Okay, well, that's an odd gesture, followed by another equally peculiar motion with his other ear and then—

Sizhui can't help gasping softly when he's able to understand him all of a sudden. Magic? Is he some kind of foreign cultivator? They've talked about such things, though never once in his life did he think he might encounter one. “Yes...” he lets himself trail off momentarily, raises his own hands, dispelling the barrier long enough to step past it.

The white is present, certainly, there's a distinct lack of a sword at the moment, however. See, he'd assumed it was someone from his home, someone who might've gotten lost and needed directions elsewhere, but this... this is something different entirely. “How did you get here?” Business before pleasure and all.
