Modern medical researcher Shen Zhixia accidentally entered the game world and became the lowest medical girl because she helped her best friend test the palace fighting game "Feng Yi Tian Xia". She has no golden fingers and relies solely on her professional medical knowledge to decipher the palace's poisonous scheme - first, she uses intravenous injection to revive the unconscious palace maid, then uses urine testing to expose the imperial concubine's false accusation of abortion, and even uses acupuncture to heal the old injury of Emperor Gu Tingyuan. During the process, she discovered that the emperor in the game was highly similar to Gu Tingyuan, who worked as a ride-hailing driver in reality (in reality, Gu Tingyuan drove part-time because his father was seriously ill, and the game was an independent work he made in his spare time). The two tested each other in the game and gradually got closer in reality. In the end, Shen Zhixia used medical skills to resolve the ultimate crisis (helping the emperor detoxify), returned to reality, and found love with Gu Tingyuan. Highlights: The contrast between modern medicine and ancient palace battles, the two-way interaction between the game and reality, and the healing feeling of the underlying counterattack.
