So Hao Ren instantly gave up asking how the sprite could forget such a piece of important information, and instead got the sprite to explain more on what she knew about the Lair of Nightmares so better understand the thing...

Like what the sprite had said earlier, she did not know too much about the Lair of Nightmare.
