Rebirth in the 70S: the Rough Man's Treasure

In her previous life, Lin Qingqing became an unruly woman due to her cousin's calculations. She was defrauded of all her money by a scumbag, and finally lost her life in a car accident. After her death, her ex-husband held her body and cried bitterly. Later, he helped her avenge her death. After returning from rebirth, on the second day of her wedding, Lin Qingqing decided to attack her husband and protect her parents. Slap the scumbag in the face, tear apart the best relatives with her hands, and trample under her feet all those who have offended her. He thrives by cooking delicious food and leads his family to live a happy life. Love, career and life bring three good harvests. The 21st century independent woman who has traveled through time cannot understand how she can't beat Lin Qingqing even though she already has her own cheating tool. I'm so angry, what's the problem? Until she suspected that the system was a traitor sent from the opposite side.
