The exact origin of the Evil Infested Ridge had been long forgotten. It is not a Burial Ground nor an Ancestral Earth, and can not be trully compared with them, but still it is a rare ground with treasures and riches. The Evil Infested Ridge had an abundance of godly ores, a plethora of spirit medicines and herbs, and it is inhabited by Heavenly Beasts and Longevity Spirits of various types and age.

Cleansing Incense Ancient Kingdom
Immortal Emperor Min Ren placed a seal inside of the Evil Infested Ridge that prevented anyone above the Ancient Saint level from entering. Even a Virtuous Paragon would be killed if they tried to force their way in, and only another Immortal Emperor could enter without problem.[?]
Difficult Dao Era
The situation changed by the end of the Emperors Era. When the Cleansing Incense Ancient Kingdom was destroyed by the Heavenly God Sect, the Cleansing Incense Ancient Sect lost control over almost all its former territory, including the Evil Infested Ridge.
In the eyes of various nations and sects, the Evil Infested Ridge was an alluring treasury and all of them wanted a part of it. So, even though the Heavenly God Sect defeated Cleansing Incense Ancient Sect, it did not dare to own the Evil Infested Ridge alone and had to share it with the rest of the world. However, only grand sects and powerful nations were qualified to enter the Evil Infested Ridge, while the small sects and ordinary cultivators could not enter.
To the Cleansing Incense Ancient Sect the most humilating part was not the lose of the Evil Infested Ridge per se, but their inability to enter it ever since. Because of their decline in power, the Sect was treated as a third-rate one and thus was not qualified to enter the Ridge.
