When celestial objects merge and strange phenomena occur in the sky, nine dragons drag a bronze coffin through the North Star, a forbidden zone, a burial island, descending to the earth. It is rumored that there is an emperor's treasure buried on the island that can enhance internal energy during training. The leaders of the sects in the North Star and the wanderers want to go to the island to seize the weapon. Among them is Ji Kong, an orphan (played by Feng Lijun). Ji Kong was adopted by his master in the sword house since he was young. His master, noticing his natural talent, paid a high price and forged thousands of swords for the holy land and sent him to the Yunxiao holy land to practice. Ji Kong and his fellow disciple go to the island together to vie for the emperor's weapon and aim for the position of the emperor.
