You Want to Steal My Pocket Dimension? Fine, I'll Be the Villain

[Transmigrate into a book + exile + personal growth + everyday life + putting scumbags in their place + reclaiming her luck!] Jiang Xuxu took a tumble and woke up as a minor character in a novel, one who died before long. The whole family were minor characters destined to die! Her stepson would die on the road, and her good-for-nothing husband was doomed to an early death too. She'd planned to lie low at the place of exile for a couple of years, then wait for the reborn heroine to take the world by storm and ride her coattails back to the capital to enjoy the good life! But who could have guessed the reborn heroine would be a scheming black-hearted woman? The people she was taking the world by storm against were Jiang Xuxu and her family. She wanted Jiang Xuxu's treasures, and the lives of her whole family as well. So what if Jiang Xuxu was a doomed minor character? So what if the other woman was the heroine? She'd knock the heroine flat with one punch and reclaim her life as a rich woman! Jiang Xuxu: That good-for-nothing, I only saved you on a whim. Don't latch onto me and mess up my life! Good-for-nothing Gu Jingchuan: What? (๑•̌.•̑๑)ˀ̣ˀ̣ Madam wants a baby in each arm? Your husband can certainly manage that! Jiang Xuxu: Watch my lips: g-u-n P.S. The heroine grows into her abilities. She doesn't start out unleashing her full power!
