With amazing costumes and outstanding martial arts, this series features an all star cast including Roger Kwok & Sonija Kwok. During the Tang Dynasty, when land was still undiscovered with just a mass amount of water, and there were outbreaks of incurable diseases. God sent two of his immortals, Tong and Hung, to seek a cure from the Mountain of Medicine. Unfortunately, along the way, they were blocked by the East Sea King and the two immortals had problems getting to the Mountain of Medicine. Just then the apparition of Kwan Yin appeared and she informed the two immortals that in order to defeat the East Sea King, they must locate the other six immortals and battle the East Sea King together. The two immortals then set waves to find the other six disguised immortals amongst the human kind.
