Forty-nine days later, a mournful howl echoed throughout the Underworld.
Sitting atop the Cumulated Thunder Cloud, Xu Yang wore an indifferent expression, calm like a still ancient well.
After forty-nine days and relying on the cultivation of a Daoist Celestial Master, as well as Luotian Dajiao, the Thunder Series Divine Skills, the Xuanyuan Divine Sword, and other numerous means including Skill Traits, he had finally dispersed the Yang God and soul of the Black Mountain Old Demon.
Although the Yang God was shattered and the soul scattered, Black Mountain did not collapse and destruct.
After all, this was a mountain range, a part of Yin Mountain's Earth Vein that existed for untold time.
Its size was too vast, its potentiality too profound, and its resources too abundant!
Even with the Xuanyuan Divine Sword drawing the essence of earth, it could not refine it in a short period of time.
