Longkong City is the sacred ground of martial arts across the land. They say anyone who can fight their way up all twenty-four floors of the Martial Arts Tower can reach the pinnacle of the martial path. Twenty years ago, the Three Great Elders conquered and seized control of Longkong City. The city's original guardians, the Five Remarkable Masters, were defeated and went into seclusion. Each began searching for the next generation of martial arts successors. To everyone's astonishment, their chosen successor was Fei San, a good-for-nothing who had loved martial arts stories since childhood but was bullied at every turn.
By a twist of fate, Fei San arrived in Longkong City, even as the forces behind the city began closing in on him. There, he encountered reclusive martial arts masters including Ding Bu'er, the Mad Hermit, Mr. Lazy Dragon, and Xiao Ma. He also gained extraordinary abilities through a stroke of good fortune and fell in love with Han Xiao, an heir to one of the guardian families. With the guardians' help, Fei San eventually reached the pinnacle of the martial path, defeated the Three Great Elders, and became the new generation's guardian of Longkong City.
