Lu Xuan traveled through the prehistoric human race and was accepted as a closed disciple by the plague god Lu Yue. He practiced hard for fifty-six years to reach the peak of refining the void and combining the Tao. He received the innate spiritual treasure Nine Dragon Robe and the ferocious beast Fei to help him overcome the tribulation of immortality. He became an immortal before Zixiao preached and attracted the attention of the heavens. When he was anointed as a god, he helped the Four Saints of Kowloon Island avoid death and change the outcome of the plague array. He was authorized by the leader to leave a ray of true spirit to transcend the list of gods.
