She said, "I'm sorry. But that's how far I can help you with this matter."
He was satisfied. He said, "Thank you for your help. This much is good enough already."
"But I have other questions, and I don't want to take much of your time. Is it appropriate to keep asking you since you're the superior commander of the army?"
She replied with a smile, "Do not worry. I am currently attending to my duties in the army just as I am speaking with you. I have divided my body in a way so I can do both things at once. I won't be able to continue in this state forever, but I can manage for a while."
He decided to ask her if demigods can reach him in the core of the world. The question was at the tip of his tongue, but he hesitated to ask it.
He hesitated because he doesn't trust her. He doesn't think that it is inappropriate not to trust her because he has no reason to trust her.
