Wearing Books from 70: the Xu Family's Sister-In-Law Tells the Truth

Where is this? Who I am? I vowed not to be picky about food and lose weight anymore, I wanted to eat meat. Who would have thought that I would wake up and change places, and become the best sister-in-law in a novel I read before. The mother of three brothers and one daughter slave, she is the best, lazy, greedy and selfish, ugh... I can't live anymore. Wait, we can still save him. It's not impossible to survive with a system. Wow! Whitening cream, raw jadeite, hundreds of years of ginseng, here I am in the 1970s!
