Su Tanxin, the concubine of the conquered country, was sent to the Dayuan Kingdom as an abandoned son to get married, and became the most inconspicuous presence in the harem of the ruthless emperor Xiao Xuance. Everyone in the palace thought that she had no foundation and was weak and could be bullied. As everyone knows, Su Tanxin is the only direct disciple of a hidden master in perfumery. She uses incense as a blade and the art of perfumery as a strategy.
When she first entered the palace, she used soothing incense to solve the concubine's insomnia and gain respite. She then used unique spices to lure out harmful insects and slap domineering nobles in the face. She cleverly set up a "fragrance array" trap to make opponents who tried to frame her suffer the consequences. She worked step by step, from being a bullied princess, to attracting the attention of the manipulative emperor. From the initial use and testing, Xiao Xuance was gradually impressed by her extraordinary wisdom and unique "scent way", and finally fell in love with her deeply.
When the conspiracies in the harem intersect with the struggle for the heir of the previous dynasty, Su Tanxin uses her superb perfume-making skills to identify strange poisons, treat noble people, pass on secret messages, and control people's hearts. She stirs up huge waves in a silent place, and finally uncovers the mastermind behind the attempt to overthrow the dynasty. She joins hands with the emperor to create a prosperous age, ascends to the throne, and honors the world as her mother.
