Can you recommend some good novels about female agents, female assassins, and female mercenaries?

😋I recommend the following novels about female agents, female killers, and female mercenaries: "The Queen of the Secret Service: The World": A modern female secret service agent transmigrated into a four-year-old girl, gradually blooming herself and becoming a queen. "Concubine is always happy: Prince, don't be too bad": The female killer Leng Qian traveled through time to become the Fujin of the Tenth Prince during the reign of Kangxi. She disrupted the historical trend of the Qing Dynasty and discovered that there was a big secret in this world. "Special Agent Boss: The World Without makeup": The 21st century's ultimate female special agent transmigrated to a fantasy continent where martial arts were respected. The strong were respected, and the strong were cool. "The World-toppling Female Mercenary: A Concubine's Daughter Is Too Arrogant": A top-notch female mercenary from the modern era, cold, arrogant, domineering, and deeply involved in many conspiracies. "Female Mercenary Time Travel 3: Crazy Concubine: A female mercenary from the modern era becomes the princess of a dynasty. She and the king love each other and kill each other. The plot is wonderful. I hope you like this fairy's recommendation. Muah ~😗
