Well what sort of answers are you expecting to get from them if not similarly broad ones? A step by step flowchart of the exact plans that Ahura had to assassinate so and so to gain power? Jing doesn't have the power to demand such answers from them (if he even trusted anyone aside from himself with them, an absolute ruler with divine authority doesn't have to spell everything out for followers to accept the plan) even if he weren't pretty badly injured as he is now. He can only really rely on Yunzi's goodwill to get him anywhere, which is probably already short due to Qilin and I imagine won't be getting much better if Jing starts whining about all the answers she owes him.
