I Told You Not to Mess with Her, So Why Are You Crying After Getting Beaten?

[Absurd comedy and meme references + real and fake heiresses + System + mysticism + villainess heroine]

Nan Yin, the great villain of the cultivation world, was cast by the Heavenly Dao into other small worlds to undergo tribulations after she killed the Chosen One with a single sword strike. She suddenly became the real heiress whom the Nan family had just brought home.

Faced with an unfamiliar environment and a new identity, the Villain System frantically found Nan Yin a hundred books about real and fake heiresses to help her cram.

After reading all one hundred crash-course books, Nan Yin felt terrifyingly powerful. She was about to test her skills and turn the Nan family upside down when she discovered that the fake heiress was a genuine pushover who took being useless to the extreme.

Her parents, who were always stern and unhappy, were actually severe social anxiety sufferers.

Her aloof genius eldest brother had a personality disorder and was ostracized by his coworkers.

Her second brother, a leading figure in the medical field, was secretly a lovesick second male lead devoted to the heroine of a tragic romance.

Her third brother, a top-tier star, was nothing but a stepping stone for the reborn male lead of an urban fantasy!

Looking at the whole family of cannon fodder, Nan Yin turned her attention to outsiders instead, wielding her mighty blade with pinpoint precision. One strike apiece, and she was completely unstoppable!

Nan Yin: Is there anything I should watch out for when playing the villain here?

Villain System: Just try to keep it down a little.
