Is there a novel with a warm system where the female lead does not have a couple, a money-making system, and a money-spending system? Can there also be a plot where the female lead has a couple?

I recommend the book,"After Dressing Up as an Exquisite Evil Granny, I Made a Fortune with the System Farming." It was an ancient romance novel about business and farming. The female protagonist had transmigrated into the ancient evil granny, but she calmly used the golden finger system to make a fortune in ancient times. She opened a chain of restaurants and lived a happy single life. This book had both a money-making system and a money-spending system. There was also the female protagonist's independent business and farming, which completely met the requirements of the question. Moreover, this book had no CP, so there was no need to worry about the female lead's emotional interference. I hope you like this fairy's recommendation. Muah ~😗
