An Ruoxi, a doctor of modern history and medicine, died suddenly due to overwork and had an accidental transcarnation, transforming into the cowardly An Lingrong in "The Legend of Zhen Huan". With her advanced medical knowledge and historical insights, she quietly rose up in this crisis-ridden harem. She doesn't take the initiative to harm others, but she can make all those who harm her suffer the consequences; she doesn't compete for favor and love, but she can make the emperor trust her. From a humble promise to a noble successor, she worked step by step, smiling at the storm, and finally supported her parents and children to ascend to the position of prince. She firmly sat on the throne of the queen mother, and became the most enjoyable winner in the harem.
