Lu Yin, a dashing soldier king who thrived in modern society, was thrown into a world of female supremacy by a mysterious force in an accident. In this world, women are the masters of the family, and men have become accessories that need to be "virtuous and virtuous". Worst of all, his true identity is an undercover agent sent by the "Reverse Alliance" - an organization dedicated to overthrowing the female order. In order to complete the task, he must disguise himself as a weak, meek "good man" and sneak into the powerful Lu family. But here, his elder Mrs. Lu, who was mean and venomous, became the biggest obstacle. She disliked Lu Yin in every way, finding faults and humiliating him everywhere. However, Lu Yin is a dashing soldier at heart, how could he just accept his anger? So, while polluting this twisted world with the spirit of modern venomous tongue-lashing, he secretly planned subversion. When everyone thought he was a pushover, he showed his fangs and told the world: You know nothing about power.
