After Overhearing the Junior Sister’s Thoughts, the Entire Sect Goes on a Killing Spree

Jiang Xin transmigrates into a book and becomes the sacrifice whose bloodline is to be exchanged for the original heroine's. She dies at birth. The original heroine takes her place as the daughter of the Tianshui Sect's leader. She grows up to play the field, then joins forces with the Demon Realm for her own selfish ends, destroys the Tianshui Sect, slaughters her fellow disciples, and even turns around to accuse the sect of colluding with the Demon Realm. Facing her impending fate as a blood sacrifice, Jiang Xin can't help thinking that maybe she should never have been born. But since she's already here... Jiang Xin looks at her birth mother, who trusts her wicked aunt completely. [Mom, your sister is so jealous of you she's gone mad. The pills she's giving you are poisonous!] Her mother, just about to take the medicine, jolts and immediately investigates, then tears her wicked sister's lair apart. Jiang Xin looks at her birth father, struggling to maintain the seal. [It's such a simple formation. Add a couple of strokes and it'll be stable. What is Dad even doing?] Her father, whose spiritual energy is depleted and who is about to be consumed by demonic energy: !!! Save me, precious girl! [Senior Brother, you used yourself as a prison to seal the ferocious beast, but died when the heroine broke the seal. The beast still became one of her fish! You're nothing but a mobile fish tank!] [Second Senior Brother...] [Waaah, every one of my senior brothers has it worse than the last. They all die at the heroine's hands.] As Jiang Xin cries, she discovers that the entire sect has defied fate, and the heroine's harem has been blown apart. Her parents are healthy, her senior brothers haven't been bewitched, and the Tianshui Sect has become the number one sect. Even she, though she can barely walk, has become a revered powerhouse!
