My Young Master Fu Yi

After the female demon cultivator Ao Lingshuang died a hundred years ago, a young woman named Yan Fu used a sacrificial spell a century later to summon her back to the mortal realm. After returning, she met the young master Fuyi, only to discover that their ancestors had arranged their marriage a hundred years ago. Fuyi took her back to Yunjia, insisting that he would marry her and make her his Dao companion.

Fuyi was a sword cultivator from a major orthodox sect, a model for all the immortal sects. Ao Lingshuang, on the other hand, was a demon cultivator guilty of every imaginable evil. They stood on opposite sides of good and evil, so how could they ever be together?
