Xiao Ge dies and is reborn in the prehistoric world, born after Pangu split the heavens and earth, as a minor cultivator. Fearless of the powerful figures of the Six Realms, he uses his knowledge of prehistoric legends to launch a series of heists. First, he steals top-grade elixirs while the Three Pure Ones are in seclusion, boosting his cultivation. Then he snatches the innate spiritual treasures Jieyin and Zhunti are gathering for the Western Religion. Disguised as an insider, he sneaks into Spirit Mountain and steals the Buddha treasure of the Tathagata, escaping from Guanyin. At the Peach Banquet, he poses as a heavenly soldier and plunders the Heavenly Court's treasury.
His heists bring Xiao Ge a rich haul and send his cultivation soaring. He builds a faction and declares war on anyone who refuses to submit, defeating his enemies with spells that combine the power of magical treasures. After fierce battles, the strongest in the Six Realms submit. Xiao Ge is worshipped by the Six Realms at the Lingxiao Palace and reigns supreme over the prehistoric world.
