The Northern Wilderness Hill was located at the central region of the Great Thousand World. During the Primordial Age, a vast supercontinent used to exist on this piece of land, which was known as the Northern Wilderness Continent.
During the Primordial Age, the Northern Wilderness Continent was the most bustling region in the Great Thousand World. However, when the Extraterritorial Race invaded the Great Thousand World, the Great Thousand World suffered one defeat after another.
Then, at the crucial moment, the Immortal Emperor stepped out and formed the Great Thousand Alliance with the forces and clans of the Great Thousand World. He then set up the Great Thousand Palace and worked with his new allies to fend off the Extraterritorial Race and prevent the Great Thousand World from imploding.
