Fifty thousand years ago, the war between immortals and demons devastated all life, and countless small worlds were destroyed. Demon Emperor Yu Yuan was killed by two immortal emperors, Changsheng and Kaiyang, and his three souls were sealed in the heavenly treasure Linglong Bi. In order to prevent the three realms of immortals, demons and humans from falling into the flames of war, Heaven automatically lowered the triple barrier. Humans cannot reach the immortal and demonic realms without ascending and experiencing thunder tribulations. The power of the immortal and demonic tribes is absolutely suppressed after entering the human world. From then on, the Three Realms were at peace, but unexpectedly, the Snow God Leng Fei who was guarding the Linglong Wall unexpectedly died unexpectedly in the forbidden area. When the two Immortal Emperors arrived, Yu Yuan Tianhun escaped into the human world!
