Yu'er didn't respond to Ming Ze but he knew that the spirit did exactly what he asked. Ming Ze could feel her aura spreading throughout the room, touching every book.
Only moments later, several books flew towards him.
When he saw the books, he showed a strange expression because they looked older than the other books that also looked very old. They even had a few tears.
He then picked up the book that had the best condition.
Much to his surprise, the cover of the book was a drawing of a black dragon and a figure with two horns.
Although the two were drawn in a simple manner, Ming Ze was certain that they depicted the Calamity Dragon and the Underworld King.
The title of the book was (The Story of the Separation of the Heaven Realm from the Nine Realms,) written by Ancestor Hong.
