Eastern Azure, Horn Pavilion.
Xu Xuan sat motionless within, quietly contemplating the Dao arts of this place.
The [Central Earth Boundary Book] lay before him, its pages constantly turning and flickering with mysterious radiance. He devoured the Dao treatises within, tirelessly extrapolating the Dharma method for that boundary of Wu Earth.
Aside from this book, three other objects lay before him.
A clay statue, a treasured painting, and a great drum.
They were precisely the three treasures of Wu Earth: [Wu Venerable], the [Restore Mountains and Rivers Again Diagram], and the [Imperial Mandate Drum].
Xu Xuan wished to cultivate the arts of Wu Earth, and Eastern Azure had been exceedingly generous, sending over the Wu Earth treasures he had seen in the past and placing them all at his disposal.
The most useful among them... was naturally the [Restore Mountains and Rivers Again Diagram]. Xu Xuan was refining it with all his strength. This object already possessed the power to evolve a world of its own, making it immensely useful for mastering that Wu Earth art.
In recent days, Mist Marsh had sent a reply, and Hou Ni had delivered the news.
Vast Marsh had explained his difficulties, saying that the Purple Mansion Dragon Kings could not leave and thus could offer little help. However, he could bring out a supreme treasure kept in reserve, and was currently working to secure it.
It seemed to be something exceedingly precious, involving "greater yin."
For now, this counted as good news. Xu Xuan had never expected much from Mist Marsh anyway. After all, none of those Purple Mansion Dragon Kings could leave their grotto-heavens, rendering them of little use.
Over the past few days, Xu Xuan had also approached Cave Azure, naturally hoping to learn Tianyu's arts-especially the so-called [Expounding the Dao].
