The veiled young mistress

Yin Zhu looked at the magic circle which was hovering over her head and her eyes widened. Even if she did not know anything about magic or elves, she knew that this magic circle was not simple—— she stepped away from the range of the magic circle and then turned on her heels to get out of the library, the man who opened the secret room right behind her but because Yin Zhu was walking while skulking behind the shelves the man could not see her. 

However, as soon as she arrived at the wooden doors she realized that they have been shut close and could not be opened anymore.

'What's going on? Just what kind of secret is hiding inside that secret room for Situ Xun to deploy such a strong magic circle?' Yin Zhu's heart was beating wildly as she hid behind the bookshelves while looking at the man who banged his fists on the surface of the door with a vicious look on his face.
