Ace female agent Qin Shumei sacrificed herself while defusing a bomb, crossing into a period novel to become a universally despised, harsh mother-in-law in the year 1960. The original owner was lazy, favored boys over girls, treated her eldest son's family like beasts of burden, and raised her youngest son into an ungrateful wretch. On the first day of her time travel, her daughter-in-law suffered a difficult labor, and she pulled a wooden cart running ten miles to deliver her to the medical station; her granddaughter was about to be sold to human traffickers, and she fought off the thugs bare-handed. Heading up the mountain to hunt wild boars, setting up stalls to earn ration tickets, opening a pig farm to get rich, kicking away troublemaking villains who came to her door, she slaps faces and punishes scumbags all the way with no one able to stop her. From a vicious mother-in-law spurned by the whole village to the head of the family with the toughest fists—the sky of this family will be propped up by her!
