Which novels had female protagonists with the surname Liu and who were very powerful?

Answer 1

"The Lucky Lady is Beautiful and Delicate" is a book that fits your requirements very well. The female lead is limited by her family background and can't get married, but because of her amazing bones and incomparable strength, she can get the man she likes. He was a tall and powerful blacksmith, and he would later become the legendary General of the North. I hope you like my recommendation. Muah ~
