Jiang Yingli, a merchant girl, lives a stable life and marries the unpopular King Su as a concubine. Unexpectedly, as soon as her husband Xiao Chenglan ascended the throne, she lowered her position to avoid the spotlight, but was extremely favored by the emperor - sitting on the dragon's throne, riding on the dragon to chase her, and his blatant doting made her the target of public criticism. Xiao Chenglan used the country as a tactic to clear out the aristocratic family, kill her old enemies, and protect her from a humble background all the way to the position of queen. After four years of secret love, she became the sole favorite of the palace. She went from timidly surviving to taking charge of the sixth palace, giving birth to a prince, and finally stood side by side with him in the turbulent times, sharing the emperor's only preference and the stability of the prosperous age.
