Mo Yuyan seemed to sense the doubts of Gu Xijiu. She laughed, "The palace master had marked all these books. Therefore, whoever had read it would leave a trace on it, which could not be concealed from the palace master."
What type of mark could he possibly do? Would he able to use a magnifying glass to identify the fingerprints of the reader?
Gu Xijiu browsed through the bookshelves for a moment before she took down a book to read.
Mo Yuyan paused for a moment as if she wanted to stop her but did not speak out.
The palace master had just ordered this person to be watched over and said that she could wander freely. Therefore, it should not be a big deal for Squire Gu to read some books.
The book that Gu Xijiu took was about alchemy, but she had put it down after she read through only a few pages.
The alchemy was rather simple. The books which the Firmament Stone showed her were much better and advanced.
