In 2008, the global sports event was held in China. One day, the underachiever of a primary school, "GG Bond" -a third grader who dreamed of becoming a martial arts expert all day long - was kidnapped by bandits who robbed the "Coynor Diamond". In the fight, he fell into a space-time tunnel and returned to an island named Olympus 1800 years ago. The residents of Olympus Island are all sports experts. The island is full of various exaggerated and even crazy sports arenas. Only sports champions will be respected by everyone.
