Outside the Black Prison Soul Extinguishing Formation.
The Abyss Demon Emperor along with the Ten Great Demon Kings could only watch helplessly as Xiao Yi broke the formation.
They were the sustainers of the formation, unable to move rashly, lest the formation self-destruct without being attacked.
Xiao Yi stood before the Formation Eye of the Great Formation.
Countless bizarre Fire Attribute Soul Powers fiercely bombarded the Guardian Soul Power at the Formation Eye.
Two Soul Powers, one Fire Attribute and the other Yin Cold Attribute, clashed head-on, creating a deadlock.
Xiao Yi frowned and coldly shouted, "Break for me."
Inside his body, the Fire Control Beast Martial Soul was instantly mobilized.
The impact of the Fire Attribute Soul Power sharply increased.
Soul Power was controlled by the inherent attribute's Martial Soul; the strength was also linked to the strength of the controlling Martial Soul.
Of course, it was also related to the level of the Soul Master.
