In order to prevent the revival of the ancient evil god, the two shuttled between the human world and the netherworld, and fought against the fallen angels, witch priests and other forces. While mastering the "Taixu Sword Body", Ye Mo gradually uncovered the mystery of his life experience - he was actually a hybrid descendant of gods and demons.
