I Cultivate the Demonic Dao in the Immortal Sect

She had once made enemies of the Three Realms, and once believed one man was her destined partner. But she ended up reduced to ashes in the Nine-Bend Yellow River Formation. A mighty Demon Venerable reduced to a lovesick fool: truly the greatest disgrace of the Three Realms! As she fell apart, she finally understood. She sacrificed her primordial spirit and forcibly stole the Mountains and Seas!!! Her life soul was remade, time turned back, and she returned to ten thousand years ago. This time, she would never be a lovesick fool again. She would not only become the Demon Venerable, but the absolute ruler of the Three Realms! She would make the Heavenly Emperor pay and leave him nowhere to run! Because scumbags deserve to die! The world is divided into three realms: the Immortal Realm, the Demon Realm, and the Mortal Realm. The Immortal Realm lies at the utmost heights of heaven, the Demon Realm in the depths beneath the earth, and the Mortal Realm in the glittering world of mortals. This woman brings a people-summoning System with her, and begins in the Mortal Realm... “The Immortal Sect's female disciple is the Demon Venerable. The scumbag Heavenly Emperor must die!”
