Is there any novel recommendation about the heroine's rebirth in another world, involving battle aura and magic?

I recommend "The Demon Lord" to you. The main character of this novel has experienced two transmigration, to the Leou Continent and the Dou Qi Continent respectively. She had magic and the ability to make magic potions. She was sold at a sky-high price at the auction and was sought after by many aristocratic families and experts. Under Elder Bing's guidance, the female protagonist cultivated a cultivation technique that had been researched for thousands of years. She cultivated both battle energy and magic, and finally embarked on the path of the peak of the strong. Let's see how the female lead leads to success step by step. I hope you like my recommendation. Muah ~
