Upon hearing the maid's explanation, Xu Zimei glanced back at the Black Mountain Old Demon.
The other party seemed somewhat embarrassed.
After all, he truly didn't understand this Ancient Library.
Previously, when he was in the Heavenly Burial Grounds, he existed in the form of the Black Mountain.
He wasn't familiar with many of the detailed aspects.
He only knew some general directions.
Xu Zimei directly asked, "What are valuable items, and what are ordinary items?"
"Our master's interests are very unique, it's hard to say.
Perhaps a story related to the old days might be considered a valuable item."
"Or maybe an old book."
"It depends on my master's interpretation."
The maid replied with a smile.
"But ordinary items are easier to identify."
"As long as they are things coming out from the Heavenly Burial Grounds carrying the ancient aura, they can access the first-level books."
"If they have phenomena of the old days, then they can enter the second level for reading."
