The Earth Immortal Realm!
An expanse stretching boundless across four states and four seas, the true extent of the Earth Immortal Realm eludes definition, ranging from the Thirty-Three Heavens up high to the eighteen levels of the Netherworld down low, and even to the mythical yet manifest extremities of Heaven and Earth.

Western Continent, Little Yan Mountain!
Teeming with green hills and winding waters, the Little Yan Mountain is a picturesque locale devoid of demonic creatures or lingering immortals, housing only beasts and birds yet to awaken their spiritual wisdom. Indeed, it could be deemed an earthly paradise.
