Change of Marriage in the Era, I Was Eating Melon in the Courtyard and Watching the Fun

(Rebirth of the era + spiritual spring space + sister exchange + control group + filthy parents + eating melons in the courtyard) What should I do if I go back to the 1970s and find that my step-sister has also been reborn, and that she has snatched away her future engagement partner? Laughing to death, an old man who is married and has three children can take it if he wants. Lin Chunxia, ​​who had worked hard for more than ten years to turn a bad hand into a good one, just wanted to change her life, eat and drink, and watch the excitement. As a result, I didn't expect that my short-lived brother-in-law from the previous life would become attached to me accidentally, and the world seemed to have turned into a sieve, with time-travelling, reborn, lucky heroines, and real and fake daughters all appearing one after another... ********* Lin Xiulan, who has been in poverty all her life, has been envious and jealous of her step-sister her whole life. After discovering that she was reborn, she immediately snatched away her step-sister's richest husband, just waiting for her husband's rapid rise to make her the richest wife that everyone envied. But she didn't want to wait and wait until she turned into a yellow-faced woman. Why did the promised richest husband turn into a coward who only drank and lost his temper at home? Look at the step-sister marrying her short-lived husband in her previous life. She doesn't have to take care of the housework or have to work hard to take care of the children as a stepmother. She is held in the palm of her hand and pampered like a princess... The short-lived husband was not short-lived, and later became the richest man. Why!
