Yong Ruo was a sensible and tough girl. She transmigrated into ancient times, into a poor, weak flower girl. But she got a strange system for healing, beauty, birth control… and many more.

He wanted to live with her for a lifetime and vowed not to marry anyone else. ‘Stressed! This is more than I bargained for!’ ‘Won’t you marry a main wife when you became an emperor?’ ‘Won’t you empty the side chambers?’ ‘Can you live with a single person all your life?’ ‘Can I not get pregnant? I don’t want any kids.’ Would the flower girl counter-attack to become a queen?
