Lu Mingyue, an orphan girl with a criminal record, has been living in the East Palace since she was a child. She started out as a smoky kitchen handyman and by chance became the personal nanny of the young prince Xiao Heng.
The palace was cold and cold, and everyone sought advantages and avoided disadvantages. Everyone else abandoned the destitute prince, but she stayed by his side and endured hardships for several years.
After the death of the late emperor, she, who had no heirs according to her ancestral rule, was sent to an ancient royal temple to become a nun. She stayed there for three years, secretly gathered her confidants, met strange people, and silently polished her city and vision in the mud.
The new emperor Xiao Heng came to power and insisted on taking her back to the palace despite numerous obstacles from the court's powerful family members and the Queen Mother. The general queen was humiliated in every possible way because of her background, and the favored concubine secretly spread stigma and framed her. Lu Mingyue tolerated the plot step by step, deposed the domineering queen, and monopolized the real power of the harem.
Instead of clinging to love, she borrowed the emperor's trust to enter the court, promoted talents from poor families, and gradually disintegrated the power that had dominated Dayu for hundreds of years, and opened a new pattern of two saints co-ruling with Xiao Heng.
The two have been dependent on each other through thick and thin since childhood, and have been deeply concerned for half their lives. However, trapped in the cage of imperial power, it is difficult to love each other, and they are full of involuntary regrets.
After the emperor died of illness, she put down the clan rebellion, purged the remaining remnants of the government and the public, broke the shackles of the secular world for thousands of years, and rose from a dusty maid to the top of the Ninth Five-Year Plan to become the founding empress of the country.
The revenge that has been endured for half a life is finally settled, including the cold fate of the noble family in the deep palace, and the vigorous counterattack to conquer thousands of miles of mountains and rivers.
