I recommend "Don't be too cold, Your Highness." The female lead was a good-for-nothing fool who had transmigrated to become a concubine, but she had a space and a bunch of good friends. She could refine pills, refine weapons, and tame beasts. Her strength could not be underestimated. At the same time, she was not easy to bully and was good at fighting back. Although the male lead was cold, he doted on the female lead. This was a fantasy romance novel. The female protagonist was very powerful, so it was definitely recommended by a strong female lead. I hope you like my recommendation. Muah ~
