I Opened My Eyes to a Killing. Since I'm Reborn, Why Waste Time?

[Both leads are reborn + no forgiveness + successful revenge + unapologetic wish fulfillment + sweet romance] Yan Zhuxing had to die before she understood. The so-called story of a magpie’s nest being taken over by a cuckoo was a lie the Yan family had fed her for more than a decade! They took advantage of her youth, destroyed her spirit, and even planned to sell her bones to the Grand Tutor’s grandson for a ghost marriage. Reborn on the day she was forced to kneel in the snow and do laundry, she snapped the neck of the vicious servant. In this life, she would send every member of the Yan family to meet the King of Hell. ...Xie Yining jolted awake from a nightmare. He had dreamed that, just before he was pierced by a thousand arrows and killed on the battlefield, a woman had stepped in front of him. At last, he found her. She was the fake heiress despised by everyone in the marquis’s household, the villainess they all hated. He ordered his subordinates to find out what she liked, hoping to win her favor. His subordinate reported, “Your Highness, that young lady’s tastes are rather unusual. She likes killing people.” Xie Yining replied, “Oh, that’s great. She kills, I’ll hand her the knife. She dumps the bodies, I’ll dig the pits. I’m happy to do it.”
