Feng Cangwu enshrouded the room with his battle qi in case that Zhang Tie was discovered by the two knights outside while his question was to confirm Zhang Tie's identity.
Why would he confirm Zhang Tie's identity? Because Feng Cangwu didn't believe that Zhang Tie could do that evil thing in Fuhai City.

Feng Cangwu might have thought about the existence of the disguised Zhang Tie. Therefore, he asked, "Who're you?"
Of course, Zhang Tie felt reassured after listening to such a question.
"It seems that you've changed a lot during the past months. When you came here at the beginning, you were as proud as a peacock and only nodded at everything. Generally, you would not tell the female servants to take a rest at such a moment!" Zhang Tie uttered.
