After Rebirth, I Became the Apprentice of My Mortal Enemy

Shock! The Lord of the God Realm is suspected to be a disciple of the previous Demon Lord! (1V1) As the Lord of the God Realm, Luan Ge has stayed in the Nine Heavenly Palace for a hundred thousand years. She is tired of it, completely tired of it, and she wants to change her life! But she died inexplicably! She was also reborn into a world whose name she didn't even remember! Several old men in the sect were silent for a moment, and they were all overjoyed, what a good seedling! Our sect has a promising future! After entering the sect, she only wanted to use various genius treasures to make a shell for herself to restore her cultivation. Just as she was admiring her perfect future body, a crimson magic burned the shell she made completely. "Disciple, why are you doing this?" Ning Huai, the master in this life, looked at her with a smile, and she could only tremble with her golden elixir cultivation. Who will tell her why the previous Demon Lord who was rumored to have died three thousand years ago became her master? ! Why is he, an upright Immortal Sect who is obsessed with this continent, so comfortable in the world? ! That master whose purpose is to benefit the common people is the previous Demon Lord Qi Yuan who slaughtered countless cities? ! Luan Ge said, this is simply unbelievable!
