Gu An did not use his Divine Sense to investigate the Cultivator at the Profound Heart Realm inside the Library Hall, as Divine Sense cannot be used for Life Span Detection, and there was no point in using it. If the other party had cultivated some Miracle Skill that could detect the probing of higher realms, it would inevitably cause unnecessary problems.
After returning to Profound Valley, Gu An went upstairs and then took out the map scroll and the book given to him by Xu Lu.
This book was entitled "Chronicles of the World," and it recorded the general situation of various places. In this book, one could find information about all the regions on the map.
Gu An carefully examined it, searching for a suitable place for his breakthrough.
