Su Qingwan, a modern history student, accidentally passed through her soul and became a concubine in the cold palace who could not survive three chapters in the ancient novel. She was also bound to the "favorability exchange skill" system - the initial favorability value returned to zero, and she even had a negative opinion of the emperor, prince, and general, and was in a difficult situation.
In order to protect herself, she relies on the system's novice skills to break through: she uses simple medical skills to help Emperor Xiao Jingyuan detoxify from acute poisons, uses her connections to find rare medicinal materials to save Prince Xiao Jinran's mother and concubine, and uses trauma medicine to treat General Lu Zhanting's old injuries. This not only unlocks benefits such as palace connections and material supplies, but also attracts the attention of the originally indifferent powerful officials, starting the "everyone competes for favor" mode. Different from traditional palace battles, Su Qingwan did not participate in the competition between the concubines. Instead, she used the exchanged detoxification skills, Qinggong and other skills to help other concubines solve their problems. Even the heroine of the original book, Queen Shen Mingyue, became her "assistant". The Queen Mother even took the initiative to mediate the Shura field between the male protagonists, making the whole process zero-torture and sweet.
As the plot progresses, she helps Xiao Jinyuan resolve the poisoning at the palace banquet, quell the rebellion of his political enemies, helps Xiao Jinran give up fighting for the throne and focus on guarding him, and allows Lu Zhanting to stay in Beijing with him on his own initiative. She also reaches a confidentiality agreement with the imperial doctor Xie Yunshu, who is also a book wearer. In the end, Su Qingwan counterattacked from a deposed concubine in the cold palace to a concubine in charge of assisting the harem. Faced with the ultimate emotional choice of the system, she could choose to build a deep relationship as an emperor and empress with her favorite male protagonist, or start an open ending with everyone guarding her. She was also rewarded by the system - the ability to travel freely between modern and ancient times, truly realizing the perfection of going in both directions. The entire book is interspersed with interactive designs where readers vote to decide plot branches. It is both sweet and refreshing. It is an innovative work in the field of ancient novels and books.
