I Became a Vicious Supporting Role in the '70s Novel

Shen Meng, a factory worker, survives a car accident that awakens a spatial power. However, the power brings troubling dreams, prompting her to sell her possessions and hoard supplies in preparation for hardship. A second accident sends her to the 1970s, transmigrated into a vicious supporting character whose tragic fate included a ruined reputation, an accidental death, and her four children suffering psychological issues from abuse and neglect, leading to their own tragic ends. Her soldier husband, previously mentally impaired after an ambush, tragically drowns in a winter river. Determined to alter this grim destiny, Shen Meng resolves to improve her reputation, guide her children, and steer her hero's descendants away from ruin. Assuming the original body's life, she vows to be filial, nurture her children, and build a prosperous future for her family. Amidst these efforts, her husband, who once held a distant relationship with her, begins to view her with growing passion.
