Bronze Divine Hall.
Yuan Tiangang curiously looked around, feeling that this place radiated ancientness and vicissitude, with some human skeletons and broken weapons scattered in the corners.
Inside, there were no legendary cultivation techniques; the images of cultivation techniques on the exterior walls of the divine hall were likely just a ruse.
They misled one to believe that there were powerful techniques inside, but upon entering, one would find it's not the case. By then, it would probably be too late.
The patterns on the walls were ancient, mostly depicting the ascension of the Winged People. The largest image was of the Winged People worshiping the moon.
Xu Xuan sat cross-legged under a tree, meditating and cultivating his Qi.
