Zhang Tie rubbed his eyes as he raised his head from the pile of books.
He was occupied in books for a whole day.
All the books were about human lives and network before the Catastrophe. Besides, there were some gnosis about cultivation and notes of clan elders of Huaiyuan Palace. Those books were collected in the library of Hidden Dragon Island while those gnosis and notes were collected in Yiyang Mountain; especially the gnosis and notes which contained many secrets of Huaiyuan Palace and various knowledge of the knight's world and could only be read by elders of Huaiyuan Palace.
Although it took Zhang Tie one day to read them, it was worthy.
