After Transforming, My Nemesis Trained Me into a Yandere

[Gender transformation, single heroine, training, with a System]

My name is Gu Xinxuan. Now it’s Gu Xinxuan, and I’m the chief disciple of the Qingyun Sect.

Hailed as “the greatest sword embryo in three hundred years.”

White robes like snow, swordlight like frost.

A pillar of the righteous path.

But my cultivation has been stuck for a long time.

When I faced my archenemy, Yin Wujie, once again, I lost.

But he didn’t kill me. He fed me a Yin-Yang Union Pill and turned me into a woman. Then he disguised himself as me and took me back to the Qingyun Sect.

Endless humiliation.

Torment.

On the surface, I swore I’d never give in, but inside, I actually wanted him to keep pretending to be me.

Then I’d only have to be his slave.

But sadly, he’s leaving to seek out stronger opponents.

I won’t allow it!

He’s mine, and I’m the only one he’s allowed to torment!

I’ll bind him to me, and we’ll never part, not for all eternity!

My name is Yin Wujie. I’m a transmigrator.

Something went wrong with the way I transmigrated. I landed straight into a game-over and was captured by the strongest demonic faction, the Nine Nether Demon Palace, becoming their newest recruit.

Luckily, I had the System’s beginner’s gift pack. Otherwise, I’d have been done for.

Wait, what?

Why are all these damn System missions related to Gu Xinxuan? He’s at the Qingyun Sect, and I’m at the Nine Nether Demon Palace. System, are you messing with me?

Years later, I finally defeated Gu Xinxuan.

The System issued a mission.

[Turn Gu Xinxuan into a woman and make her completely loyal to you. Reward: a ticket home.]

Yin Wujie clutched the bottle containing the Yin-Yang Union Pill, hesitated a little, but still fed it to him.

Uh, is Gu Xinxuan acting strange?

I feel like the way she looks at me is a little off.

Damn it!

She’s actually pretty good-looking?

Holy crap, what if there’s something wrong with me too?
