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 replaced by the original heroine. She dies at birth. The original heroine takes her place as the daughter of the Tian Shui Sect's leader. When she grows up, she becomes a player, allies with the demon realm to conquer the Tian Shui Sect for her own selfish reasons, slaughters her fellow disciples, and even turns around to falsely accuse the sect of conspiring with the demon realm. Facing the fate of being sacrificed, Jiang Xin thinks that maybe she should never have been born. But since she's already here... Jiang Xin watches her mother trust 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 in alarm, investigates at once, and tears apart her wicked sister's lair. Jiang Xin watches her father struggle to maintain the seal. [This formation is so simple. Just add a couple of strokes and it'll be stable. What is Dad even busy with?] Her father, out of spiritual power and about to be swallowed by demonic energy: !!! My precious girl, save me! [Senior Brother, you sealed the ferocious beast inside yourself, but died when the heroine broke the seal. The beast still became one of the heroine's fish! You're just a walking fish tank!] [Second Senior Brother...] [Waaah, every one of my senior brothers had it worse than the last. They all died at the heroine's hands.] Jiang Xin cries and cries, then realizes that the whole sect has defied fate, and the heroine's harem has been blown to pieces. Her parents are healthy, her senior brothers haven't been bewitched, and the Tian Shui Sect has become the number one sect. Even she, though still learning to walk, has become a great figure admired by all!
