Liu Zhiwei gave up her old name and assumed the pseudonym "Su Qing". As the daughter of a pharmacist, she successfully blended into the new generation of beautiful women by virtue of her proficiency in pharmacology and her insight into the weaknesses of personnel in the palace. She started out as the lowest-ranking prostitute. She appears to be docile and non-competitive, but in reality she is ruthless and decisive. She used her past life memories and unparalleled pharmacological knowledge to bring down those who framed her one by one: the hypocritical sister, the concubine who was swaying, the treacherous minister who framed Zhongliang... Every time she struck, she was precise and ruthless, but she was completely eliminated.
Her sudden rise attracted the attention of Duan Wang Xiao Xuanjing, who seemed to be frail and sickly, but was actually dark and tolerant. Xiao Xuanjing was the younger brother of the current emperor, but because his biological mother died young and he was "frail", he was left out and secretly accumulated strength. He discovered that Su Qing's means and resourcefulness were far beyond that of an ordinary prostitute. After several trials, the two formed the most secret alliance. Su Qing cleared the obstacles in the harem for him and provided him with dirty information about his former opponents; Xiao Xuanjing became her most solid backing, providing her with protection and power.
On the road to revenge, Su Qing's identity was on the verge of being exposed several times, but she and Xiao Xuanjing worked together to resolve them. In the end, after defeating all her enemies and turning her own sister into a madwoman, Su Qing stood in front of the regretful emperor and revealed her true identity. When the emperor collapsed, Xiao Xuanjing launched a palace coup to replace him.
The new emperor ascended the throne and Su Qing was canonized as queen. She was not a canary in captivity, but the only person who stood side by side with the new emperor and shared the mountains and rivers. She truly realized the counterattack of returning from hell and taking charge of the world.
