Are there any novels about female agents, killers, or rebirth?

I can recommend a few to you! 1. "Crazy Concubine: The Supreme Third Miss": The female lead, Piao Wu, was the top professional assassin of the organization's secret agents. After being betrayed by her closest person, she was reborn as the abandoned Third Miss. However, her unyielding personality destined her to have a storm and show the temperament of a strong female secret agent. 2. "Reborn National School Hunk: Killer on Campus": The female protagonist, codename R, was a special agent killer. In an accident, she transmigrated to a useless middle school student, but she still fought with the scumbag sister and abused the scumbag boy on campus, showing the true colors of a strong female agent. 3. "Rebirth Junior High School: Young Master Mu, Your Wife Has Fallen Again": The female protagonist, Shi Ling, was a handsome male boss who was reborn as a fat otaku junior high school student in the era of the recuperation of spiritual energy. She concealed her identity as a special agent and exploded in the eSports circle, showing the strength of a female special agent. I hope you like this fairy's recommendation. Muah ~😗
