Victorious Fighting Buddha Sun Wukong asked Daode Tianzun to upgrade his Ruyi Bang, a magic staff. Yet the golden furnace suffered accidental sabotage, causing the Ruyi Bang to fall to the mortal realm and go missing. Afraid of irritating Sun Wukong, Daode Tianzun sent his disciple Silver Horn to go to the mortal realm secretly to look for it. Having lost his celestial power in this world, Silver Horn made acquaintance with the village bully, Haiwa, in a fight with the bandits. And Haiwa, under Silver Horn's threats and temptations, agreed to look for the Ruyi Bang. By the Laoyao River, Haiwa was forced to reveal his true self, the Ruyi Bang, at a critical moment in the battle with the Nine-Head Worm, which solved the mystery that had haunted Haiwa for 18 years. However, Su Wukong made his appearance at this time, making Silver Horn and Haiwa wonder if there was turmoil in Heaven. Who sabotaged the golden furnace? Who was upgrading the Ruyi Bang? What was the secret behind Victorious Fighting Buddha's origin? In the sky-shielding flood brought by the merged evil monster, how would the Ruyi Bang sacrifice itself to save the day for the peace of the world?...
