Chapter 801: Azure Blood Dragon Ancestor

```

At this moment, within the Qianren Cave Mansion, Yang Xiaotian arrived at a certain palace.

Inside the palace, there were many books piled up.

Although eroded by the passage of time, these books still appeared as good as new, emitting a faint fragrance.

The entire palace was filled with a power similar to that of the Ages Grand Formation.

It seemed that the Qianren Sword Ancestor also had considerable research on the Ages Grand Formation.

Yang Xiaotian approached these books and casually flipped through them, only to discover that they encompassed everything, including swordsmanship manuals and array formation secret books, as well as various books on astronomy and geography.

Yang Xiaotian took out that secret book of the Qianren Sword Formation and read it carefully from beginning to end, then reviewed some of the cultivation techniques and ultimate arts left by the Qianren Sword Ancestor.
