I Used the Return System to Corrupt the Entire Demon Realm

Su Man, the sect master of the Hundred Flowers Sect, led her entire sect through countless hardships, eventually becoming the number one sect in the Immortal Realm.Who knew that during the Immortal Sect Grand Ceremony, she would be betrayed by her most beloved disciple and lover, her body destroyed and her dao extinguished! After being reincarnated on Earth and living a new life, she gained a lot.After experiencing birth, aging, sickness, and death, when she opened her eyes again, Su Man discovered that she had been reborn into her own world, and had become the saintess of the Demon Realm, the enemy of the entire Immortal Realm.Just as Su Man wanted to break away from the Demon Realm, she was bound by a hundredfold return system.Return to the Immortal Realm?Are you kidding me? Wouldn't it be better to transform the Demon Realm into the sacred land of the six realms?
