In 2008, a grand global sporting event is held in China. "GG Bond," a struggling elementary school student who is obsessed with martial arts novels and constantly fantasizes about becoming a martial arts master, is one day taken hostage by robbers attempting to steal the "Koh-i-Noor" diamond. During the struggle, he accidentally falls through a time tunnel and ends up on an island called Olympus, 1,800 years in the past. The residents of Olympus Island are all sports experts, and the island is filled with exaggerated, even insane sports arenas, where only sports champions earn everyone's respect. The "Koh-i-Noor" diamond is the island's sacred artifact and the key for "GG Bond" to return to 2008. The island's rule states: to climb the Mountain of Light and retrieve the "Koh-i-Noor" diamond, one must win championships in all the island's sports events. "Superman Qiang," a sports prodigy determined to become the island's chief, becomes "GG Bond's" formidable rival.
