Immortal Emperor Ling Xuan is betrayed by the one he loves most. His cultivation is crippled, his memories erased, and he is cast into an abyss ten thousand feet deep. Everyone believes he has become a cripple. But in his amnesiac state, his supreme dual-polarity divine and demonic Emperor Arts awaken completely. He crushes Immortal Venerables with his bare hands, slaughters his way through the Demonic Ruins, and scatters the Dao across the Three Realms. As the Demon Venerable falls and the Demonic Eyes emerge, he has forgotten his own name, but he has never forgotten to protect the mortal world.
