It seems that the whereabouts of the Nine Nether Divine Pot are known to the Nine Nether Fairy, or else she wouldn't be so vigilant after hearing Basil Jaak's response.
"Where did you get the Nine Nether God Pill you possess?"
After forming a barrier of wary True Qi, the Nine Nether Fairy asked Basil Jaak the second question, clearly with hostility.
"Heh, with such hostility towards me, do you think I'll tell you anything? Do you think you're interrogating a criminal?"
Facing the hostility of the Nine Nether Fairy, Basil Jaak certainly wasn't going to comply easily. Why should he answer whatever she asked?
"Who exactly are you, speaking so boldly? What's your name?"
Despite Basil Jaak's evasive response, the Nine Nether Fairy felt quite embarrassed but persevered and asked Basil Jaak another question.
