Can you recommend some good gangster novels with powerful female leads?

I recommend the following two underworld novels to you: 1. "Black Belly Not Concubine": The female protagonist, Shen Xing 'er, was a veritable mafia missy. After traveling back to ancient times, she launched a series of counterattacks. Not only was she skilled in martial arts, but she also had a sharp reaction. She also had a series of underworld skills that allowed her to be like a fish in water in the palace. 2. "The All-powerful Underworld Queen": The female protagonist was the underworld queen, but unfortunately, she was killed and traveled back to ancient times to become a weak princess. After she woke up, she decided to fight back. She took every step she took to capture the black-bellied king and rebuild her kingdom. The female lead was extremely brave, intelligent, and brave. She was very powerful. I hope you like this fairy's recommendation. Muah ~😗
