Reborn in the Eighties: The Timid Old Lady Turns the Tables

[Period setting + putting scumbags in their place + reborn + building wealth + no forgiveness or reconciliation + a lightly ensemble cast] In her previous life, Grandma Qian cared for her paralyzed mother-in-law and her mentally ill younger brother-in-law, and raised five children. She worked tirelessly like an old ox, while her family drained her dry. Her husband went into business overseas and became a billionaire. Grandma Qian thought her good days had finally arrived, but he promptly kicked her out with nothing and brought home the woman he'd loved for years... With no choice, Grandma Qian survived by collecting scraps, until a freight truck hit her and left her partially paralyzed. Her sons took her compensation money and abandoned her in a rundown shack to die. Eldest son: “I'm the eldest legitimate grandson of the Lu family, a man of status. How could I look after an old woman who collects trash?” Second son: “Mom, you always play favorites. I never get any of the good stuff.” Third son: “Mom, can you stop making trouble and getting in the way of my studies?” Her beloved youngest daughter: “Wait for me, blondie!” Only the daughter who was least loved, whom she had thought the least of, and who was so poor that Grandma Qian sold her, gave her a proper burial. When Grandma Qian opened her eyes again, she was back on the day she was supposed to arrange a marriage for her eldest son, the very day she was going to sell her second daughter... Duan Xiao was a workaholic. He had only recently built a business empire when he took a bad fall at a celebratory banquet and died in his prime. Luckily, he didn't end up in the underworld. Unluckily, he transmigrated into a book, becoming a cold-hearted, impossibly handsome and dashing military officer. His good mood didn't last long: he discovered he was a cannon-fodder character...
