The following is one of the transmigration novels that I am most confident in recommending to you: "The Divine Phoenix Is Not a Concubine." At first, the female protagonist was thought to be a good-for-nothing who could be bullied by anyone, but in fact, she (he) was a rare genius. She became powerful through alchemy, refining, imperial treasures, and taming beasts, becoming a character with a dual personality. Although she was cold and heartless at first, through her interaction with the male lead, she gradually became gentle and became the male lead's absolute love. I hope you like my recommendation.π
