He was summoned by the female 8-Essence Paragon after she sacrificed 60% of her longevity.
He has the body of a monkey and uses a staff (think Sun Wukong) (See footnotes).
His exact background is shrouded in mystery, thus, it is unknown whether he actually hails from one of the former 3000 Lower Realms or somewhere else.
During the two thousand years in which Meng Hao was away from the Mountain and Sea Butterfly, Dao Fang received extensive support from the Immortal God Continent and the Devil Realm Continent and managed to reach the 9-Essences realm.
However, even though Dao Fang managed to reach the 9-Essences realm, the dao of the ninth essence was forced upon him and was not his own dao. This made his battle prowess plummet and it would require at least four of him to battle a true 9-Essences Paragon.
- Sun Wukong, also known as the Monkey King, is a god figure who features in a body of legends, which can be traced back to the period of the Song dynasty. He appears as a main character in the 16th century Chinese classical novel Journey to the West. (Source: Wikipedia) Visit Mythology Wikia for more details.
