The master of a lineage, or a Primordial Ancestor, was among the most special existences in the Eight Domains of Heaven and Earth.
They received the boundless favor of Heaven and Earth's will, born with the supreme potential to reach the realm of a Young Venerable.
The level of their existence was extraordinary.
A Primordial Ancestor who was extremely firm and yang was even more terrifying.
For such an existence, there were typically two paths.
Either they could preserve their vital essence, embracing yang while bearing yin to achieve self-perfection.
Or they could unleash it, uniting yin and yang to be reborn from destruction.
But once unleashed, unless another Primordial Ancestor who was their yin-yang counterpart appeared, the consequences would be dire.
There were two examples: one was the Thunder Saint Venerable, the other the Bliss Demon Venerable.
