I Have Too Many Older Brothers to Count

Lu Jingjing, female. Her father is unknown, and her mother is a heartthrob to everyone. As a young woman weighing a whopping 120 kilograms, Big Lu tried every possible way to save herself... and failed spectacularly at every one of them. At last, one day, Big Lu sold herself to the System. Under the terms of their contract, she set off on a cross-dimensional quest to find her father. All she had to do was get all seven Lu Dads in seven parallel worlds to acknowledge Lu Jingjing as their daughter, and the System would help her slim down to 50 kilograms. That was the simple-sounding core of the contract. The tricky part was: One, Lu Jingjing had never seen what her dad looked like. Two, the System said that her dad was different in every world. Three, her dads were rich and powerful, and not easy to get close to. Four, her dads' sons.
