The seventh-floor library is never open to the public because the most dangerous "books" in the world are stored there.
Lin Xi, an ancient book restorer, stole the forbidden key in search of his missing grandfather. She successfully found the "Minghai Secret Book" mentioned in her grandfather's notes, but found that the cover of the book was as warm as skin and the texture was pulsating like blood vessels.
When she tried to put it back in horror, a mysterious voice sounded behind her: "Miss, what you are holding is not a book, but a dragon's eye."
In an instant, the truth of the old world collapsed before her eyes. Knowledge comes alive, memory becomes a cage, and her touch has awakened the sleeping abyss... ——For mortals to peep into the secrets of gods, the price will be all yours.
A very nice book
