Ethereal Dao Sect. It was a medium-class sect in the Cloud Heaven Realm.
In the Cloud Heaven World, there were many Heaven Realm experts. For tens of thousands of years, they had been conquering everywhere, seeking to occupy other small worlds.
The Ethereal Dao Sect's invasion of the Fire Source World could be traced back to 10,000 years ago.
However, at that time, the Fire Source Realm was jointly controlled by the Tang Mountain Sword Sect and the Blazing Sun Palace. Their strength was enough to resist them, and they had never given the Ethereal Dao Sect too many chances.
After the decline of the Blazing Sun Palace, the Ethereal Dao Sect seized the opportunity to invade on a large scale and constantly encroached on other territories. Now they had already occupied 70% of this world.
