[Traditional Fantasy + Invincible Protagonist + No System + Pure Action + Ruthless + Villain Protagonist + No Female Lead + Empress] A thousand years ago, Ye Tian and Mu Yao ventured into a forbidden zone on the Tianwu Continent and awakened the will of a dark being. Ye Tian chose to bind himself to the darkness for a thousand years. Mu Yao, however, inherited the legacy of the Tianwu Emperor, and a thousand years later became an unparalleled empress. Ye Tian was trapped in the forbidden zone for a thousand years, while his former junior sister wanted him dead. For a thousand years, the forbidden land tormented him with the source of the uncanny. He endured it all, asking only that his beloved remain safe. Now, it had all become a laughingstock. “I will make sure the heavens can never cover my eyes again!” Ye Tian fell to the demonic path in a single day, becoming the source of a dark upheaval! I am darkness, I am the uncanny, I am the source of destruction. From then on, he seized the secrets of heaven, extinguished the path to immortality, and destroyed the road to emperorship. He unleashed a dark upheaval, bringing countless Supremes and Saints to their deaths! A struggle for supremacy in a golden age? No one in this era will become a Great Emperor! For this is my age of darkness! When Ye Tian's cultivation surpassed that of a Great Emperor, the lofty Empress of Yaochi lowered her proud head. In tears, she begged Ye Tian to forgive her, saying she regretted what she had done. “Heh. The only thing you regret is losing your cultivation as a Great Emperor! Today, I will kill you and scatter your soul!”
