My Master Is the Demon Lord

One day, Jiang Fei realized that she had actually transmigrated into an old-school Mary Sue master-disciple novel.

And she was one of the cannon-fodder characters.

So she decided to come ashore and take revenge on the scumbag.

However, by the time Jiang Fei crawled up from the seabed, a hundred years had passed in the cultivation world.

Over those hundred years, seas had become fields and fields had become seas, buildings had risen and fallen, and a great many things had happened.

For instance, one villain had single-handedly turned the cultivation world into the demons' domain and driven her beloved senior brothers off to the desolate Demon Capital...

Jiang Fei: "..."

P.S. 1. The heroine's true form is a jellyfish.

2. Both leads are each other's first and only, happy ending.

Theme: When your heart has somewhere it longs to go, why fear a long and difficult road?
