Lin Yue, a modern social animal, wakes up and transforms into the cannon fodder Xia Dongchun in "The Legend of Zhen Huan" who cannot survive three episodes. She is also bound to a "cheating system" and her first task is to "survive three episodes." Knowing the direction of the plot, she worked step by step to avoid "one foot red", used her wit to resolve the difficulties of her mother-in-law and the pressure of Concubine Hua, and snatched her life back from the gate of hell.
When she first entered the harem, she tried to hug Zhen Huan's thigh but failed. Instead, she was regarded as a thorn in Concubine Hua's side and was forced to bear the humiliation while copying scriptures. In the Princess Wen Yi incident, she took a risk to save the princess and formed a brief and complicated bond with Cao Qinmo; facing Concubine Hua's fatal frame-up, she narrowly escaped death and secretly planned a counterattack. Zhen Huan became suspicious of Concubine Hua because she was making things difficult for her. The two went from testing to joining forces, and each showed their magic in the confrontation with Concubine Hua, but they were still unable to shake her foundation.
As Shenmeizhuang's false pregnancy crisis, An Lingrong's darkening, Chun'er's death and other incidents unfolded one after another, Lin Yue gradually gained a foothold in the turbulent harem. She helped Zhen Huan escape by feigning death, raised her fourth elder brother with her own hands to pave the way for the future, and even caught a glimpse of the shocking secret of Chun Yuan's death while dealing with the Queen and Concubine Hua. However, just when she thought she could move forward steadily as Xia Dongchun, the system suddenly issued a new command - random identity switching.
