A survivor of the apocalypse transmigrates into a book, into the body of a vicious cannon-fodder female character, and finds herself with three children, all of whom are major villains. She also meets a lucky girl who, like her, was switched at birth. With no other choice, she teams up with the lucky girl. In the 1970s, they make soap, open a factory, and get rich together. The three kids start turning out a little crooked and want to kill people, so she takes them to run a pig farm where they slaughter pigs every day. At last, the kids say they're exhausted. The children pull all sorts of outrageous stunts, and she forces them back onto the straight and narrow. Then the man she hasn't seen in years comes back. She kicks him out, but he shamelessly clings to her again. All she can do is take the kids, drag the man along, open factories, buy a house, take the college entrance exam, fight the scheming tea girl, and climb back to the top of her life.
