According to legend, three thousand years ago, foreign enemies invaded northern China. The emperor borrowed dragon balls from Shenlong in order to gain great power. The emperor promised to return the dragon balls to Shenlong after winning the battle. Unexpectedly, the emperor died in battle, and the whereabouts of the dragon ball was unknown since then, and Shenlong was trapped in the mountains because of the loss of the dragon ball and could not return to the heaven. More than three thousand years have passed in a blink of an eye, and there is only one man named Wu Dong left in the family who guarded the Dragon Ball. After Wu Dong's family search and investigation for generations, he has determined the whereabouts of the Dragon Ball. The Dragon Ball is in the emperor's tomb, and was buried with the emperor as a funerary object. But now that the archaeological team has unearthed the emperor's tomb, it is almost impossible for Wu Dong to get back the Dragon Ball. At this time, Australian boy Josie came to China with a Sino-Australian archaeological team to find his father, because Josie's father was the captain of the Chinese archaeological team. At the airport, Josie met a girl named Xiaoling by accident. Xiaoling's mother, Dr. Li, happened to be a colleague of Josie's father. Josie's father and Dr. Li were at the excavation site of the emperor's tomb at this time. So Josie and Xiaoling walked together, they didn't know that the tomb robbers were quietly following behind them.
