I recommend the following time-travel novels. The female protagonists are all very powerful ~ 1. "Crazy Wife Evil Emperor is too black-bellied": The female protagonist was the black-bellied and powerful queen of the 21st century mercenary world. She was also the genius young master of an ancient martial arts aristocratic family. She had transmigrated to the Fengyun Continent and used her powerful martial arts to fight against magic. 2. "Spacetime Savior: The female protagonist is a transmigrator without a system or a cheat. However, she continues to grow stronger in various spacetime battles and becomes a spacetime saviour. 3. "The Concubine is Alluring": The female protagonist is a transmigrator with a strong aura and excellent cooking skills. She transmigrated from an advanced civilization and was hunted down by all kinds of crazy people. However, she gradually rose to power with her powerful abilities. I hope you like my recommendation. Muah ~
