On the Seventh Day After Her Death, the True Heiress Uses Metaphysics to Dish the Dirt?

【Imposter Heiress + Fortune-Telling + Gossip + Breaking Free of Shackles, the Entire Plot Goes Off the Rails!】 Lu Xianyu died, came back to life, and died again. In her first life, her fate had been switched and the author had it in for her. With those two disadvantages stacked, she died in the most perfunctory way imaginable. Now in her third life, she returned to the night of the seventh day after her first death and came back as a corpse. Naturally, she would take revenge on everyone who had wronged her. Her first target was Pei Xianchan. Her second was the birth mother of Pei Xianyu, the fake heiress. Pei Xianchan liked the Eighth Prince, so Lu Xianyu would help make that happen. Lu Xianyu saw that Pei Xianchan wasn't a member of the Pei family. Her mother had been cuckolding the marquis for years. And she and the Eighth Prince might even be... cousins? What a juicy piece of gossip! Lu Xianyu was delighted, and waited for the truth to come out. As for Pei Xianyu's birth mother, she would be much harder to deal with. She was a member of the Wu clan, but the clan had vanished a century ago. No one across the entire Tianlu Continent could find them. They had been lying low in secret for years. Whatever they were plotting had to be something earth-shattering, enough to shake the whole Tianlu Continent. No rush. Her daughter had become Lu Xianyu's disciple, so she had no doubt she'd find the woman eventually.
