Many transmigration fantasy novels have plots where a good-for-nothing becomes a genius. I recommend the following to you: 1. In <<The Unparalleled Divine Doctor's Defiant Demonic Concubine>>, the female protagonist became a good-for-nothing and a dandy young lord after transmigrating. However, her cultivation improved by leaps and bounds, and she became a powerful divine doctor with ease when she refined pills and weapons. 2. "The Traitor's Counterattack: The Evil Prince Dotes on Concubine Nitian". The female lead was considered a cripple, but later cultivated to become an alchemy expert and even met the love of the Evil Prince. 3. In <Abandoned Daughter Counterattack: A Genius Alchemist>, the female protagonist was considered a good-for-nothing, but later became a genius Alchemist and turned the tables on her to become an expert. 4. "The Ghost Emperor's Wife: Lady Nitian". The female protagonist was considered a good-for-nothing, but later became the Lady Nitian and started a rebellious love affair with the Ghost Face King. I hope you like my recommendation. Muah ~
