At this moment, Yang Xiaotian arrived at the entrance of the Inner Hall.
The doors of the Inner Hall were tightly closed, with countless Sword Dao patterns etched above them.
Yang Xiaotian took a look and then, with a wave of his hands, unleashed the Sword Qi of the hundredth Stone Sword.
Instantly, the patterns of Sword Dao lit up, and the doors of the Inner Hall slowly opened.
As the doors opened, a vast hall appeared before Yang Xiaotian.
The hall was several thousand square meters, with a floor made from polished Mysterious Iron Stone. A large bookshelf stood to the left wall, and the right was adorned with a variety of swords.
Yang Xiaotian stepped forward to browse through the books on the shelf, finding Swordsmanship Manuals, Cultivation Techniques, and manuals for punches and palm strikes, but predominantly sword techniques.
All these martial arts, at the minimum, were Innate Top Martial Techniques.
Many were Divine Skills.
