I Became a Vicious Supporting Role in the '70s

After a car accident leaves her bedridden, factory worker Shen Meng discovers a spatial power, but its side effects manifest as disturbing nightly dreams. Fearing a future of scarcity, she liquidates her assets to stockpile supplies. Another accident during a supply run leads to Shen Meng transmigrating into a 1970s period novel. She is now a vicious supporting character destined for a tragic end, having opposed the female protagonist, Jinli. Not only is her reputation ruined, leading to her death, but her four children suffer psychological issues due to neglect and abuse, resulting in their own tragic fates. Furthermore, her soldier husband is left mentally impaired after an attack and drowns in a winter river. To alter this grim destiny, Shen Meng, inhabiting the original body, vows to redeem her reputation and guide her children, descendants of a hero, towards a better path. She commits to filial piety and nurturing her family towards prosperity. Meanwhile, her husband, formerly distant, begins to show her increasingly passionate attention.
