He's all set to protest her calling Shen laoshi pretty, because even if it's true (it probably is, given how goo-goo-eyed lao Zhao's been at him since day one) it's... undignified and disrespectful. Calling him dumb is probably even moreso, but he's still very very angry at him about sacrificing himself and inspiring lao Zhao to follow him, so that he's not even going to consider protesting. But any thought of that flees his mind as she continues.

"YE-FORKING-ZUN?!?!" he yowls at the top of his lungs. "What do you mean calling HIM ge?! Did you miss the part where he's an EVIL OVERLORD WHO PLOTTED WORLD DOMINATION FOR TEN THOUSAND YEARS, TORTURED LAO ZHAO AND MURDERED SHEN LAOSHI!?!?!?!" he screeches.
