After Dying a Horrible Death and Being Reborn, I Stole the Scumbag's Home!

(Transmigration to ancient times + spatial storage + household intrigue + substituted bride + face-slapping and revenge + comeback, strong 1v1 partnership) Her stepsister didn't want to marry Xue Lingfei, the adopted son of the prince's household, who had a title but no real standing, so she forced Hua Yunchu to take her place. Hua Yunchu managed his affairs inside and out, swallowed her pride, and helped him rise to the highest ranks of court. But he believed her stepsister's lies, thinking Hua Yunchu had forced herself on him. Together with her stepsister and her biased parents, he poisoned her day after day. On the day she gave birth, he even forcibly took the baby away, leaving mother and child dead. Only as she lay dying did Hua Yunchu learn that Xue Lingfei had always loved her stepsister. He'd married her only to use their child's umbilical cord blood to save her stepsister. She and her child died, while the scum of a man and his vile lover rose to wealth and power. Reborn in a new life, she discovers that the cheat-code spatial System is actually her hapless best friend. If she's not going to take down the scumbags, what is she waiting for? She exposes the scumbag man and his poisonous sister's affair, costing them their chance at power. She uncovers her adoptive mother's schemes and sends her to prison. She destroys her scumbag father's ambitions and ruins his reputation. She takes down anyone who stands in her way, whether they're Buddha or demon, and shows tenderness to just one person. But this young prince, rumored to have been betrothed to her as a child, isn't he supposed to be a dissolute playboy? Who is this young war god, capable of bringing peace to the world with his pen and conquering it on horseback with his sword? But that's not the point. I only wanted to use you as a shield. I never meant to get myself involved, okay? Young Prince: It's easy to invite a god in, but hard to send one away. A Chu, since you've gotten involved with me, you're stuck with me for life. Don't even think about leaving! Meanwhile, her hapless best friend: I'm just here for the gossip. Don't drag me into this!
