Yang Huai understood.
Immortals and gods who wielded terminal Great Daos such as destruction and endings were, because of their paths, mostly inclined to hasten the great momentum of heaven and earth toward its end, using it to cultivate.
The orthodox immortals and gods, however, more often entered major worlds about to step into twilight to cultivate, borrowing the momentum and strife of heaven and earth to comprehend the mysteries of the Great Dao.
Yet some demons, devils, immortals, and gods cared for none of that. They would actively interfere with heaven and earth, slaughter living beings, and force the world to prematurely head toward destruction and its end, thereby obtaining the Great Dao mysteries or cultivation resources they required.
