After the Legitimate Daughter Went Mad, She Beat Every Household and Palace Scheme with Memes

I, Shen Qingyuan, the legitimate eldest daughter of the Marquis's household, was honest, dutiful, gentle, and virtuous in my previous life. Yet my stepmother set me up, my half-sister harmed me, my father sold me off, and I died mysteriously in the palace.

Reborn, I finally understood: good people die young, bad people live a thousand years, going crazy is the safest option, and making jokes is the surest way to stay alive!
