How to annoy a god

Xiang Yu continued to step in and out of the door, a mocking smile playing on his lips. "So I can't go outside?" he asked innocently, knowing full well he was irritating the old man.

"Will you stop doing that?" he said, exasperation clear in his voice. If this idiot didn't have his son's divine sense inside of him he would have left him on that forest floor. 

Xiang Yu's smile widened. "Doing what?" he repeated, feigning ignorance. Right on the verge of losing his temper, the old man snapped his fingers, and the door disappeared. 

He took a deep breath, trying to maintain his composure. "You are here because I need your help saving Han Xin."

Xiang Yu's expression turned to that of confusion. "Who? I don't know anyone surnamed Han."

The old man, "…" Was he doing this on purpose? This little demon was like a toddler persistently pushing his buttons.
