Gu Long
The 9th Prince aka "Iron Fingers" wants the royal seal to become emperor. To get it he must kill the current emperor and his two new born sons elder brother Tao Hing and younger Wong Szu Tai, and their bodyguards Gu Long and Li Chin. Gu Long and Li Chin escapes with the boys and they end up separated, Tao Hing goes under the care of the "3 Holy Fools" at Shaolin temple and Szu Tai under the care of the Prime Minister (Ku Feng) and are unaware of each other's whereabouts or existence. Tao Hing is raised by the 3 Holy Fools who are forbidden to come out of their dwelling due to corruption in Shaolin Temple and learns the secret Yijin Jing, however he is naive and knows nothing of his lineage though he carries the royal seal. He constantly gets into fights with a traitorous monk who secretly works for the 9th Prince but bests him in every scuffle. Wong Szu Tai however being raised by the Prime Minister and Gu Long is well aware of the existence of his brother (though he does not know who he is), the evils of the 9th Prince, and getting revenge. Gu Long tells him the only way to beat the 9th Prince is to go to Shaolin and get the Yijin Jing. The 9th Prince hears of the existence of Wong Szu Tai and visits the Prime Minister. He attempts to test if Wong knows kung fu but Wong holds back as he realizes he cannot beat the 9th Prince.
