As soon as he's up Lan Wangji's leg, he shakes it as if the limb has offended him. In a way, it has. What on Earth is Wei Ying planning to do up there, anyway, turn back into a human and rip off his pants? Good Gods and Immortals in Heaven, what on Earth could that boy be thinking?

The audience isn't sure they like this part of the fight, as they can't see Wei Ying anymore. They're only treated to this view of Lan Wangji shaking his leg and it's not even a particularly enjoyable dance to watch.

At least one of them grows bored and yells at them to actually fight.
