Spoiled or Deceived? I'll Send the Entire Marquis's Household to Hell

【Two powerful leads + revenge on scumbags + true and fake heiresses + everyone begs for forgiveness + decisive and ruthless + strong female lead】 Born the legitimate daughter of a marquis, she was framed by villains and accidentally lost as a child. Ten years later, she returns in triumph, only to find herself outshone by an adopted stand-in heiress. The fake heiress frames her, and after her birth parents use her for all she’s worth, they cast her aside. Her brothers look down on her, and her relatives ignore her. In this life, she won’t try to please her cold, heartless parents and brothers ever again. Once the truth comes to light, she rises to untouchable heights. Even if they kneel and beg her to forgive them, she’ll never be a fool who lets herself be used again! Mu Yu kills gods when she meets them and Buddhas when she sees them. Since you can’t tell good people from bad, she’ll send your whole family to hell… Only one man, cloaked in sheep’s clothing, gives a cold snort and says, “My Yu’er is the person in the world who deserves to be cherished most.”
