Alchemy Waste? No, It's the Queen of Elements!

Song Sisi, a social animal in a modern laboratory, died suddenly and traveled through ancient times, becoming a penniless orphan with unknown origins. After being rescued by Su Mubai, a gentle country doctor, she originally wanted to live in peace, but due to the pressure of life, she had to return to her old business - packaging modern chemical knowledge into "alchemy", starting from making soap and purifying salt, improving her life step by step and shocking her neighbors. However, her "whimsical ideas" not only attracted the gentle protection of Su Mubai, the warm-hearted brother next door, but also attracted the serious injury of Mo Yu, a sinister intelligence organization who pretended to have amnesia. She also aroused the strong interest of Xiao Yu, the third prince who paid a private visit incognito and had the world in mind. Xiao Yu concealed his identity and approached her as a gentle and talented person, intending to recruit her to serve his grand hegemony. Song Sisi was unknowingly involved in the increasingly turbulent undercurrent: Mo Yu's enemy's temptation, Xiao Yu's careful calculation, and all the forces eyeing her "alchemy"... Between dependence and misunderstanding, warmth and calculation, protection and harm, she must use her own wisdom and knowledge to survive in a strange era, and finally make her own choice.
