The towering red walls cannot lock away the hidden edge; the strict palace rules cannot trap the tenacious soul.
Shen Yinwei, the daughter of a loyal minister of the former dynasty, kept her name anonymous to avoid further trouble in the family, and entered the palace as a medical woman, considered a low-level talent. She kept in mind the family motto of "hide one's strength and keep one's humbleness" and just wanted to survive quietly in the palace. However, an unexpected encounter made her remembered by the cold and sinister emperor Murong Heng.
The turmoil in the harem, the arrogance and domineering concubine Hua Guifei, the snobbery and difficulty of the housekeeper, and the open and secret attacks among the concubines forced her to put away her gentleness, rely on family medical skills to resolve the crisis, and use her thorough wisdom to manage every step of the way. She went from being an inconspicuous talent in the remote West Cross Courtyard to becoming a being that even the court and harem did not dare to underestimate. However, she encountered a vicious plot when she was pregnant with Liujia, and was heartbroken because of the emperor's balancing act.
Murong Heng, the iron-blooded emperor who ascended the throne at a young age, was accustomed to using tactics to balance the court and regarded emotions as a fetter. It wasn't until Shen Yinwei turned around and left that he realized that the neglected sincerity had already been planted deeply. On the way to pursue his wife, he put down his imperial figure and clumsily but sincerely made up for his mistakes. After watching the gentle woman in the past transform into a powerful man with power and strategy, he realized that "a thousand miles away is not as good as your smile."
From surviving within the palace walls to fighting side by side against rebellion, from misunderstandings to relying on each other for life and death, they test, pull, and redeem each other in the whirlpool of power and intrigue. Shen Yinwei used his strength to defeat all those who looked down upon him, vindicated the injustice of his family, and worked hand in hand with Murong Heng to create a prosperous age; Murong Heng turned from a cold-hearted emperor to a maniac who dotes on his wife, and promised her "only you in this life, no concubines in the harem."
