章 508: Challenging Wolf King

The pioneer of soul path — the legendary Gu Master at the apex of rank nine, Spectral Soul Demon Venerable once said:

"In this huge world, the best option for soul strengthening is Dang Hun mountain, and for soul refinement, the best choice is Luo Po valley. One mountain and one valley, with both, one can obtain great success in soul path and sweep every obstacle in this world!"

Thus, Dang Hun mountain and Luo Po valley became known as the soul cultivator's sacred lands.

Fang Yuan was well aware of how huge a help these two sacred lands could provide since obtaining Dang Hun mountain.

His thousand man soul was cultivated through the guts Gu on Dang Hun mountain.

Guts Gu was the number one Gu in increasing the foundation of the soul; it had no side-effects and its efficiency was extremely high as well.
