Naruto System in One Piece - Chapter 262

Five years ago, Qiao Nian was schemed against by her sister, Qiao Xin. After spending a night with a stranger, Qiao Nian got pregnant. She did not know who the father of the child was, and eventually gave birth to a stillborn. Under the machinations of her mother and sister, Qiao Nian was stripped off of her shares in Qiao Group and sent to a mental hospital.Five years later, her younger sister, Qiao Xin, was going to be married off to the Second Young Master of the Gu family. He was rumored to be extremely ugly. On the day he was born, the doctor predicted that he would not live past twenty years old. Her mother could not bear to see Qiao Xin marry such a person and thought of Qiao Nian, who was still locked in the mental hospital. Overnight, Qiao Nian was taken out of the hospital to replace Qiao Xin in her marriage into the Gu family.Her mother said, “It's a good thing that Qiao Nian, this good-for-nothing, can replace Xin'er to be a living widow in the Gu family. If Xin'er were to marry into that family, I would be heartbroken.”Qiao Xin said, “Mom, don't say that about Sister. If it weren't for her, I wouldn't know what to do. I'm just worried that Sister wouldn't agree.”Her father said, “Xin'er, you're too kind. Have you forgotten how Qiao Nian slandered you five years ago? She has no self-restraint. She got pregnant before marriage and even gave birth to a stillborn child. We're treating her well enough by letting her marry someone from the prestigious Gu family! What right does she have to be picky?”Qiao Nian sneered. Back then, the scheme against her had only succeeded due to a freak combination of factors, causing her to suffer. She was going to get back at all of them! Everyone thought that her actions were borne from a combination of a loser's mentality and mental illness, but little did they know that this marriage would be a strong union as impactful as Mars crashing into Earth! Taking advantage of her brilliant skills in medicine, Qian Nian made various trashy people and scumbags eat their words. In the blink of an eye, her multiple identities shocked the world as each of them got exposed. It turned out that she was rich enough to rival a country!Later on, Second Young Master Gu placed a pair of Qiao Nian's miniature clones in front of her. Faced with these two children who resembled her and Gu Zhou, Qiao Nian blinked in shock. “When did I give birth to your children?”
