Tan Rou only learned that she wasn’t the Tan family’s daughter when she was seventeen years old. She went from being a rich young lady to living in the slums. The parents she adored belonged to someone else, and this series of knockdowns was hard for a seventeen-year-old girl to accept. She wailed like a child for the sake of proving this was all a lie. The vicious words she spouted had hurt her biological family but she didn’t notice. She thought the Tan family was her real family despite them seeing her as an eyesore, and was even naive enough to want to befriend the Tan family’s real daughter, Tan Jing. Alas, the latter drugged her drink and arrange for a thug to rape her. Tan Jing even brought their classmates along to catch them in the act so Tan Rou was now tainted for life. After being reborn, she looked down at the man she was stepping on. Tan Rou swore not to be a useless wretch in this life or be bullied to death. She would stomp on those who wronged her and make it up to her real family. They wouldn’t have had to die tragically on the streets in the past life had it not been for her. Tan Rou turned completely evil after crawling back out of Hell. Everyone claimed that the real young lady was educated and talented, while the fake young lady was arrogant and incompetent. Tan Rou scoffed upon hearing this. She held back her brother from trying to stand up for her. “We have all the time in the world. Let’s just wait and see.” Just as everyone was waiting for Tan Rou to make a fool of herself… A top-class perfumer, a top scholar, a world champion… The fake young lady’s multiple identities kept getting exposed one after another, bumping her up to number one on the trending search, shocking the world. Wait, where was the promised humiliation?

Back in 1996, when the daughter of the Old Xie family, Xie Wanying, said she wanted to be a doctor, many laughed. "Phoenix begets phoenix, dog spawns dog. A truck driver’s daughter becoming a doctor is as likely as a sow climbing a tree." "I’m not just going to be a doctor, I’m going to be a female chest surgeon," said Xie Wanying. Her words provoked even greater waves of disdain within the doctors' community. Relatives who were doctors ridiculed her mercilessly: "Do you know how high the admission scores are for medical students? Do you think you can make it?" "There are zero female chief chest surgeons in the country. Who do you think you are!" A bunch of people mocked her: "You'll probably only get into a third-rate medical college and end up as a health worker in a small county town. It's easy to imagine what sort of marriage you'll have." After the college entrance exams, Xie Wanying entered the top surgical class in the country with the highest science scores in the province, with department heads in the Capital’s top-tier hospitals vying for her from her internship beginnings. "Student Xie Wanying, come to our digestive surgery department." "No, she must come to our urological surgery—" "Pediatric surgery is in short supply of female doctors like student Xie Wanying." Circles of relatives and friends: … At this time, Xie Wanying independently completed the youngest Tetralogy of Fallot surgery in the country, represented the national association of chest surgery at an international medical forum, and published the world’s first minimally invasive heart valve repair surgery, becoming truly the foremost surgeon in the field of female surgery! As for the marriage concerns that everyone "worried" about: A brother from the Returned Overseas Faction, a hot bachelor within the Capital, changed his QQ profile picture to Junior Sister Xie. The young CEO, a handsome man, came to the hospital every day with flowers, keen to offer a diamond ring. Not to mention, a whole host of suitors had long since worn a path to the Old Xie Family's doorstep...
