Crazy batch of sober and reborn heroine (a hot 80s daughter-in-law who was squeezed to death by her mother-in-law in her previous life) + mean mother-in-law (identity swapped with the heroine after rebirth); rebirth memory + group buying group system + two-way identity swap;
In her previous life, she was a hot daughter-in-law from the 1980s. She was exploited by a top-notch mother-in-law and betrayed by a scumbag husband. She eventually died of exhaustion and was reborn with overwhelming hatred. Coincidentally, the top-notch mother-in-law was also reborn due to an accident. Their rebirth instantly triggered a two-way identity swap - the heroine assumed the identity of the mother-in-law (who had the economic power and voice of her husband's family), and the mother-in-law assumed the identity of the heroine (who was oppressed by the whole family and dependent on others).
The heroine relies on the rebirth memory + group buying system to "rectify the family tradition" as a mother-in-law: stop sucking blood from her parents' family, force the scumbag husband to make progress, punish the weird sister, and at the same time use the system to engage in group buying side business (reselling eighty-year-old scarce materials) , making a lot of money; the mother-in-law, in her role as the heroine, experienced the harsh oppression of her previous life - being discussed by the neighbors, being indifferent to the scumbag, and being disliked by her parents. She also had to deal with the heroine's counterattack, and she went from being arrogant and domineering to being embarrassed.
While using her mother-in-law's identity to accumulate capital and collect evidence of the bad husband and her mother-in-law's previous lives, the heroine took advantage of the opportunity of identity swapping to let her mother-in-law witness her evil deeds. Finally, after swapping back her identity, she tore apart the scumbag husband and the best mother-in-law in public, divorced to stop the loss, and counterattacked with the system and wealth to become an 80-year-old female boss!
