Lady Ghost, This Humble Monk Offers His Greetings!

One hundred thousand years ago, the Three Realms were ruled by the divine, human, demon, and fiend races. Each race had its own territory. Though they had their differences, they did not interfere with one another. Then, dissatisfied with the status quo, the divine race joined forces with the fiends to launch a surprise attack on the demons. After wiping them out, they allied with humanity to destroy the fiends. In the end, humanity was not spared either. From then on, the divine race took complete control of the Celestial Realm and called themselves the Heavenly Gods, masters of the realm. Humans and demons in the Mortal Realm were forbidden from ascending to immortality. The fiends were as powerful as the divine race, so the Heavenly Gods hunted them down to extinction. The few fiends who survived fled into the Bottomless Abyss, living in a land without sunlight.

To obtain divine and fiend stones for cultivation, the Heavenly Gods mercilessly forced human and demon laborers to mine them in the Kunlun Mountains. At last, humans, demons, and fiends could no longer endure the divine race's rule and began their path of resistance.
