Must I Be Cold on the Outside and Sweet Within After Transmigrating into a Villainous Master?

My name is Gu Yi. In my previous life, I died at the hands of Mo Ling, the female demon who ruled the entire cultivation world.

She was the master I revered most, the rival I admired most, the mountain I could never surmount, and the person buried deepest in my heart.

But she was obsessed and insane. She overturned the entire cultivation world just to keep me in her grasp and make me her captive.

In the end, I pierced her core with my sword and killed her, then used up all my strength and died... Now I've been reborn, back at the age of fourteen, when I first entered the Demon Sect. This time, I will save Master Mo Ling no matter what. If I can... I want to save myself, too.

My name is Mo Ling. I'm a transmigrator, and I not only took over this female demon's body, but inherited her memories from her previous life as well.

If I do nothing, it seems I'll eventually be stabbed straight through by my own beloved disciple, Gu Yi.

Luckily, I transmigrated to the point when she was fourteen and had just joined the Demon Sect. It's not too late. I'll set the world's course right...

Not a chance! Before transmigrating, I was a huge social recluse. How am I supposed to talk to this mysterious sword-training girl, whose broken family and psychological scars leave her with not so much as a smile?

Guess I'll just have to change Gu Yi through my actions.

Years later...

Gu Yi: "Master, I'm going to stab you now, okay?~"

Mo Ling: "...Huh?"
