The so-called sacrifice is actually a live human sacrifice.
Or, to be more precise, the sacrifice of the life of a being of the same species as the sacrificer.
Life sacrifice is not only limited to Evil Gods; it also exists among True Gods. Some clergy, when activating certain special Divine Arts, often sacrifice their own soul and life.
After all, although Soul Power and life power are not as high-ranked as Divine Power, they are one of the origin powers of the world and can be directly absorbed and utilized by the Divine.
However, True Gods possess rationality and a sense of rules, whereas Evil Gods are often obsessive and mad.
Many True Gods disdain the method of life sacrifice as a means of killing the chicken to get the eggs, but for the Evil Gods, it's the easiest way to please them.
After all... what Evil Gods love to see most is the massacre and chaotic slaughter among living beings.
