Even though Chu Wanning didn't enjoy physical contact he held Wei Wuxian close. The height and the fall is terrifying but not as much as if he were on a sword. It was strange perhaps but the worst has already happened: they're free falling. But unlike relying on a sword while flying, he can at least rely on himself.

So while his heart is hammering in his chest, he isn't pale and shaking. He twists in the air so he's facing the dragon coming towards them, holding out his hand to cast a barrier...right over the dragon's mouth. It wouldn't stop it from opening or closing but it would prevent them from being in between those jaws if they close while also preventing it from biting anyone else. At least, for now.

The barrier glimmered gold and another flick of his wrist creates another barrier, this one blue, right under them. A barrier for blocking wind more than anything but it catches the air and slows them as they fall.

He tried to adjust their position, to put himself on the bottom both to keep an eye on the dragon (but also so he'd fall first).

"Don't let go." The words are a command but the way he holds onto Wei Wuxian is firm but not painfully so.
