Chapter 656: Nightmare Lord! Condensing the Law Seal

The Abyss Ancestor is the only existence throughout the ages that is undying and indestructible.

It truly achieved an everlasting life like that of an immortal.

Because of this, although the Abyss Ancestor hid in the human world, its power remained the goal that cultivators desperately sought throughout the vast long time.

However, this kind of power is too terrifying, shrouded in mystery, defying heaven and untouchable; when mortals dabble with it, misfortune is bound to follow.

Like when the Ancestor of the Imperial Spirit Palace rebelled against the Sunset Sect in his pursuit of the power of the Abyss Ancestor and the secret to everlasting life, he used the blood of the Abyss Ancestor as a foundation and countless living creatures as experiments, attempting to fully grasp the secrets of the Abyss Ancestor.
