He's expecting something so shameless from him, and as soon as Wei Ying does that, Lan Wangji spins to try and buck him off, knowing full well that the lock of his feet will be a tight one, but at the very least, it should keep him from being able to sit up properly to punch him.

The force of the spin should pull him up slightly from the ground enough so that Lan Wangji can lurch forward and slam him back into it, and then pin him down onto the ground with his hips and his hands.

The crowd stops passing around money and stops cheering to look, uh, confused as to what is happening to this fight. To be honest.
