Azaroth was facing the Sect Master of the Night Mountain Sect and his group of close comrades. He responded to the Sect Master's words, "I never said I brought an army with me. Why would I need an army to deal with you when I have personally arrived?"
The question he asked was rhetorical. Azaroth wasn't expecting an answer from the Sect Master of the Night Mountain Sect. However, the Sect Master of the Night Mountain Sect didn't know that. He answered Azaroth, "You are overconfident if that's what you truly believe this."
Azaroth smirked at those words and spoke, "We'll see about that." After saying those words, he moved from his spot, leaving a dust cloud at his position.
