Which novels could he recommend that had powerful female leads and good transmigration fantasy novels with assassins or secret agents in their past lives?

😋I recommend the following novels to you, I hope you will like them: "Defiant Little Demon Concubine: Beauty Preceptor": The female protagonist is the world's number one assassin agent. She transmigrated to the body of the good-for-nothing Third Miss of the Vermillion Bird Continent. She practiced magic, controlled divine beasts, refined pills, and abused scumbags and evil women. Accompanying her was the mysterious state preceptor. The two of them were strong and united. The plot was not bad! "The Cold King's Favorite: The Defiant Secret Concubine": The female protagonist was a peerless assassin from the 25th century. She transmigrated to the Great Xuan Kingdom's Feng Clan's useless missy in the Starfall Continent. She turned the world upside down, killing rats, beating up lackeys, tearing apart white lotuses with her bare hands, and stepping on scheming women. The plot reversal was stunning! "Secret Agent Miracle Doctor: The Two-Faced Assassin Concubine": The female lead was a top ace assassin in Country Z. Her body was the body of the young lady who was regarded as a good-for-nothing in the Tianxun Continent after changing her soul. She became obsessed with cultivation, but she became a great person in both ways. The emperor tried his best to win her over, but her heart was captured by a black-bellied killer. The plot was full of ups and downs. I hope you like this fairy's recommendation. Muah ~😗
