The river of blood was cut into two. The Invisible Sword eventually pierced through the boundary of the Netherworld Dharma Formation and stabbed into the Netherworld Old Daoist's heart, which exploded with a loud bang.
The unparalleled radiant light shone and brightened the dark North Sky Heavenly Region for a moment.
The explosion continued. The barrier of the Netherworld Dharma Formation was pierced through and it was collapsing at an extremely fast speed.
Standing on the blood river that was about to wither, Jian Wushuang slowly spat out a mouthful of turbid breath. A hidden red light flashed in his left hand.
The river of blood was formed by the condensation of killing intent and death aura. It could easily contaminate the soul and cause the besiegers to lose their way.
However, there was one thing that allowed Jian Wushuang and the others to easily avoid being devoured by the blood river.
