A mysterious black book, a star map that flickered with countless stars, and a saber that seemed to be formed by countless feathers appeared in front of Chu Zhou at the same time.
At the same time, a message entered Chu Zhou's mind, telling him the name and origin of such a thing.
"So, this civilization ruin was left behind by the ancient Zenith civilization, the Woox civilization. These three things are the three treasures of the Woox civilization: the Book of Profound, the ancient map of the Starry Sky, and the Divine Wing Saber."
Chu Zhou was pleasantly surprised and continued to read the information in his mind.
As the name suggested, the Book of Profound was engraved with the 36 most dazzling Profound Meanings of the Woox civilization. It was also the most important inheritance of the Woox civilization.
