Liu Ming casually took a book from the shelf, glanced through it, and his expression changed slightly.
The book in his hand was surprisingly a tome recording the forbidden knowledge of ancient formations of the Ancient Demon Clan.
Liu Ming had some understanding of formations, and the formations recorded in this tome seemed incredibly profound. If Qian Rupin were here, she would probably jump with joy.
Liu Ming sighed lightly, took another tome, and found it still discussed formations.
He stepped back, glanced at the bookshelf beside him a few times.
Both sides consisted of two independent bookshelves each, making a total of four.
Each bookshelf was marked with an ancient demon rune. Although Liu Ming couldn't understand the meaning of these runes, he vaguely guessed they were used to differentiate the content of the bookshelves.
He had just looked through the tomes on the first bookshelf on the left.
