Dongfang Poxiao, a skilled bounty hunter, chases a treasure thief named Gao Dawei and learns of the Western smuggling syndicate, the Shamen Organization, from an informant, Bano. He also discovers the existence of the legendary "Five Treasures of the Northern King". Teaming up with adventurer Ouyang Xue, he uncovers an ancient desert ruin and retrieves one of the treasures. Meanwhile, his ex-lover Su Na and rival Lei Zu obtain another treasure, the "Northern King’s Cauldron", and betray him, joining forces with the Shamen Organization. Ouyang Luo, the richest man in the Western Regions and a guardian of the Northern King’s legacy, recognizes Dongfang Poxiao as the reincarnation of the Northern King and swears loyalty to him. With the help of his trusted allies—the calm Qing Shuang and fiery Hong Lian—Dongfang Poxiao unravels a grand conspiracy involving three powerful families and the smuggling syndicate. At an auction, Dongfang Poxiao exposes a fraud involving counterfeit relics, leading to a chaotic battle. Using the power of the Northern King’s Ring, he forces three family heads to confess their crimes. However, the Shamen Organization’s leader, Liu Lie, challenges him to a deadly game—hide and seek with the Northern King’s Cauldron as the prize.
