Grandmaster of Demonic Cultivation: You Never Saw Me

Standard blurb:

Wei Wan is Wei Wuxian's younger sister, with the childhood name Qingqing.

She got lost as a child and nearly fell into the hands of human traffickers. Thankfully, she was found, but the successive deaths of her parents left her with an obsessive streak.

"What's mine is mine. Even if I throw it away, no one else is allowed to pick it up!"

When they first meet, the girl sits atop a wall and brazenly behaves outrageously toward the elegant young man.

At Golden Carp Terrace, she brazenly pulls off the young man's forehead ribbon and belt, tying him to a chair. He submits to her helplessly.

"You're mine, and mine alone.

"Your eyes are mine, your hands are mine, and your life is mine, too."

"You're mine, too."

"Lan Xichen! Hurry up and get me some lip rouge!"

"Coming."

Unhinged blurb:

Everyone knows there's a little demon girl in Yiling. You can't provoke her, and you can't get away from her. If you anger her, you won't even need her to lift a finger before you're already dead.

What? You want to know why?

Her brother is Wei Wuxian, the Yiling Patriarch. Is that enough?

Her brother's husband is Lan Wangji, who always goes wherever chaos breaks out. Is that enough?

Her husband is Lan Xichen, the Zewu-Jun of the Gusu Lan clan. Is that enough?

Her senior sister is Jiang Yanli, the most cherished member of the Jin clan. Is that enough?

Her nephew is Jin Rulan, the Jin clan's second most cherished member. Is that enough?

Her senior sister's younger brother is Jiang Wanyin of the Yunmeng Jiang clan. Is that enough?

Her brother is sworn brothers with Nie Huaisang of the Qinghe Nie clan. Is that enough?

What? Still not enough?

Her mother, Cangse Sanren, had a junior fellow disciple named Xiao Xingchen. Is that enough?

And behind her is the entire Yiling Wei clan. Surely that's enough?

What? You want to know what to do if you happen to offend her?

Buddy, come on. I'll treat you to a good meal. After that, it's time for you to hit the road.

Warnings:

1. Original female lead x Lan Xichen

2. The heroine is obsessive, but mostly just likes to act spoiled

3. The original story won't be copied directly, and there are many changes to canon. Read with caution.

4. I feel for Wei Wuxian and the others, and I'll do my best to make things right.

5. Wei Wuxian won't die, and he'll keep his own body.

6. The heroine is incredibly powerful! This is important.

7. She'll focus on her ambitions at first, then the romance later. (Isn't thirteen years enough time for them to fall in love? "Waggles eyebrows")

Theme: Giving closure to the things that still hurt
