I recommend the ancient romance novel,"The Mistress Shocks the World," to you. The female protagonist is famous in the business world and is also a mafia lady. Later, she transmigrated to another world and became a concubine's daughter. In the end, she became the mistress of the house. This book has elements of the underworld and strong women. It meets your needs. I hope you like this fairy's recommendation. Muah ~😗
