A Martial Dao Great Power cultivates a True Soul.
Above the True Soul is the Yin God.
A Yin God is a deity of the Netherworld, the epitome of Supreme Yin and Wuji. In a way, it can be considered to have already gained some of the power of a Divine Spirit.
Once a Yin God sheds its physical body, over time it can easily become a terrifying existence like an undying Resentful Spirit King, a Ghost King, or an undying Nether God.
In this world, there are also Martial Artists who abandon their physical bodies, specializing in Yin Refining Body to become a Nether God.
However, it is difficult for a Nether God to survive. As far as Qin Feng knew, for such an existence, the Nine Great Celestial Tribulations would be countless times more ferocious, making them nearly impossible to endure.
According to the legends of the Sea Race, the Ancient Times were more than a million years ago.
