The Qihuang Kingdom is run by women. As the head eunuch, Yan Lang’s dream was to wander aimlessly in life, and resign with honor while disguising herself as a man. However, Yan Lang unexpectedly encountered the biggest failure of her career when the new empress ascended to the throne. Wait a moment! Who could explain to her why the empress was a man? Yan Lang panicked and barely managed to beg him to spare her life. Before she could even celebrate, he forced a pill down her throat. "All this drug will do is to keep you in check. Behave well, and I will make sure you have nothing to worry about," he said. "Just be a good empress! Starting today, I’ll be your loyal subject during the day, and serve you well at night," she said. Every day, Yan Lang wandered on the edge of life. It wasn’t until one day that the empress discovered her secret that Yan Lang, the provincial commander, was a woman!
