This Assassin Isn't Exactly Proper

Fan Tiantian, who came from the 21st century and has a master's degree in obstetrics and gynecology and the dual identity of a killer, time-traveled to a twelve-year-old girl in the Qian Dynasty in an accident. Fan Tiantian accidentally picked up an unconscious teenager, and later discovered that he turned out to be Zhao Xiao, the former crown prince of the Great Yong Dynasty who had his parents killed by the Qian Emperor's conspiracy to usurp the throne. Two helpless teenagers struggled to survive in troubled times. In a few years, Fan Tiantian relied on his wisdom and knowledge to not only earn huge wealth for Zhao Xiao, but also to train Zhao Xiao with a "shadow" secret guard team that was widely heard of and a nationwide intelligence network called "Thirteen Fragrances". With the change of dynasties, mercenaries from various local governments took pride in themselves. Fan Tiantian and Zhao Xiao led their men to occupy Hanzhong, launched an uprising, and raised the banner of national restoration. In five years and dozens of battles, Zhao Xiao grew from a boy who was dancing spoons to a domineering king, but Fan Tiantian was always the most concerned and important person in his heart.
