The Sin Clan was not simply a race, but a group of truly powerful races. In ancient times, almost every one of them was no weaker than the Human Clan. They had competed and flourished alongside them, being considerably mighty.
A hundred thousand years ago, the most fierce Divine War erupted among the various races. They contended for the most prosperous and wealthy territories, affecting the entire Gulan Continent. Ultimately, in the Divine Battlefield, the most terrifying Divine War in history took place, and these races all suffered defeat. The victorious Human Clan exiled them to the Land of Chaos, on the other side of the Abyss Valley.
Moreover, they were forced to make a Heavenly Dao oath, forbidding them from crossing the Divine Battlefield and traversing the Abyss Valley for a hundred thousand years, or else they would suffer the punishment of the Heavenly Dao oath, with their race obliterated.
