But the Ethereal Slaughter Art wasn't all that Tang Yin had at his disposal.
BANG
Tang Yin's hair was suddenly overtaken by darkness from its original bloody crimson shade. His abyssal black eyes instead, turned crimson. It was as if his hair and eyes had exchanged colour. Abyss Emperor Transformation!
Whatever small amount of Devouring Principles wafted through the darkness rapidly changed course and surged towards Tang Yin in a spiral. However, in the Hectic Chasm Holy Land, Space Principles reigned dominant. All other Principles were almost non-existent except for Darkness Principles, Shadow Principles, Gravity Principles, Time Principles and Earth Principles.
Tang Yin had to wait for a couple of minutes for all of the surrounding Devouring Principles to gather. Usually, he would be able to finish the Abyss Emperor Transformation within a second.
However, this was only because of the average quantity of Devouring Principles lingering in the air.
