At this moment, in order to deal with Jiang Chen, Primordial Heavenly Sovereign had devoted all his energy to him, thereby neglecting his own defense.
And this, was the opportunity for the Ancestor of Underworld River.
Previously, protected by the Celestial Cloud, the Ancestor of Underworld River was uncertain about breaking through the defense of this treasure, and hence had not made a move until now.
However, now, in order to suppress Jiang Chen, Primordial Heavenly Sovereign had sacrificed the Celestial Cloud, and without the protection of this treasure comparable to an Innate Treasure, the defense of Primordial Heavenly Sovereign had undoubtedly greatly weakened, providing the Ancestor of Underworld River a chance to kill him.
In his earlier days before achieving Tao, Primordial Heavenly Sovereign would never have made such a basic mistake, neglecting his own defense in order to suppress an enemy.
