The Nine Yang Celestial Skill was the Enlightenment Technique created by the Nine Yang Supreme, Yang Xiao's master from his first life and one of the most terrifying and powerful experts in Heaven and Earth.
It contained two Saint Emperor Level Divine Techniques.
The World-Destroying Divine Wheel.
And the Indestructible Golden Body.
These two Saint Emperor Level Great Divine Techniques were terrifyingly powerful. They were the Supreme Divine Techniques the Nine Yang Supreme had relied on to attain the Dao. In his first life, Yang Xiao's foundation was fixed, so he never had the chance to learn them.
He had coveted them for quite some time back then.
Now, rebuilding his life, he naturally had to build a solid foundation.
He had to master these two Supreme Divine Techniques.
