Sanzo hasn't stayed among the living by means of fair fights, not at all. He was not about to give Cassian any space to recover and lunged after him, aiming another blow for just under Cassian's ribcage. Good luck spouting insults when you really can't breathe!

The cigarette had been dropped at some point but Sanzo didn't give a shit, right now he just wanted to knock the shit out of Cassian.
