Ma Feilong is the 19th generation descendant of Ma's Thunder Fist. However, he was knocked down by a female passerby in public in an accident, which made him lose his reputation overnight and became a "master of a different generation". Later, Ma Feilong learned from a reporter that the female passerby was a big shot. She turned out to be a legendary figure in Hong Kong's Western boxing world, a woman who once had an undefeated record of 40 fights - Chen Zhen!
